So I'm going to talk today + +00:04.180 --> 00:10.000 +about a fun rewrite I did of the BinDat package. + +00:10.000 --> 00:00:12.400 +I call this Turbo BinDat. + +00:00:12.400 --> 00:00:14.001 +Actually, the package hasn't changed name, + +00:14.101 --> 00:16.801 +it's just that the result happens to be faster. + +00:16.901 --> 00:19.521 +The point was not to make it faster though, + +00:19.621 --> 00:22.241 +and the point was not to make you understand + +00:22.341 --> 00:23.440 +that data is not code. + +00:23.540 --> 00:27.120 +It's just one more experience I've had + +00:27.120 --> 00:31.280 +where I've seen that treating data as code + +00:31.381 --> 00:33.522 +is not always a good idea. + +00:33.622 --> 00:36.162 +It's important to keep the difference. + +00:36.162 --> 00:38.880 +So let's get started. + +00:38.881 --> 00:40.642 +So what is BinDat anyway? + +00:40.742 --> 00:43.602 +Here's just the overview of basically + +00:43.602 --> 00:44.962 +what I'm going to present. + +00:45.062 --> 00:47.842 +So I'm first going to present BinDat itself + +00:47.843 --> 00:00:49.039 +for those who don't know it, + +00:00:49.039 --> 00:00:51.923 +which is probably the majority of you. + +00:51.923 --> 00:55.363 +Then I'm going to talk about the actual problems + +00:55.363 --> 00:58.882 +that I encountered with this package + +00:58.882 --> 01:01.843 +that motivated me to rewrite it. + +01:01.843 --> 01:05.043 +Most of them were lack of flexibility, + +01:05.044 --> 01:09.924 +and some of it was just poor behavior + +01:09.924 --> 01:13.364 +with respect to scoping and variables, + +01:13.364 --> 01:16.324 +which of course, you know, is bad -- + +01:16.424 --> 01:20.724 +basically uses of eval or, "eval is evil." + +01:20.724 --> 01:24.884 +Then I'm going to talk about the new design -- + +01:24.985 --> 01:28.005 +how I redesigned it + +01:28.105 --> 01:31.365 +to make it both simpler and more flexible, + +01:31.365 --> 01:32.965 +and where the key idea was + +01:33.065 --> 01:35.205 +to expose code as code + +01:35.305 --> 01:37.525 +instead of having it as data, + +01:37.625 --> 01:39.605 +and so here the distinction between the two + +01:39.706 --> 01:44.085 +is important and made things simpler. + +01:44.085 --> 01:46.405 +I tried to keep efficiency in mind, + +01:46.405 --> 01:52.405 +which resulted in some of the aspects of the design + +01:52.505 --> 01:54.886 +which are not completely satisfactory, + +01:54.886 --> 01:57.046 +but the result is actually fairly efficient. + +01:57.146 --> 01:59.286 +Even though it was not the main motivation, + +01:59.287 --> 02:02.967 +it was one of the nice outcomes. + +02:02.967 --> 00:02:06.006 +And then I'm going to present some examples. + +02:06.007 --> 02:08.167 +So first: what is BinDat? + +02:08.267 --> 02:10.567 +Oh actually, rather than present THIS, + +02:10.667 --> 02:12.407 +I'm going to go straight to the code, + +02:12.507 --> 02:14.246 +because BinDat actually had + +02:14.346 --> 02:16.647 +an introduction which was fairly legible. + +02:16.748 --> 02:21.128 +So here we go: this is the old BinDat from Emacs 27 + +02:21.128 --> 02:23.448 +and the commentary starts by explaining + +02:23.448 --> 02:25.848 +what is BinDat? Basically BinDat is a package + +02:25.948 --> 02:30.247 +that lets you parse and unparse + +02:30.247 --> 02:31.527 +basically binary data. + +02:31.627 --> 02:34.648 +The intent is to have typically network data + +02:34.749 --> 02:35.849 +or something like this. + +02:35.949 --> 02:38.328 +So assuming you have network data, + +02:38.328 --> 02:41.528 +presented or defined + +02:41.628 --> 02:44.569 +with some kind of C-style structs, typically, + +02:44.669 --> 02:46.009 +or something along these lines. + +02:46.109 --> 02:49.120 +So you presumably start with documentation + +02:49.120 --> 02:52.809 +that presents something like those structs here, + +02:52.810 --> 02:57.130 +and you want to be able to generate such packets + +02:57.230 --> 03:00.249 +and read such packets, + +03:00.349 --> 03:02.090 +so the way you do it is + +03:02.190 --> 03:04.570 +you rewrite those specifications + +03:04.670 --> 03:06.010 +into the BinDat syntax. + +03:06.110 --> 03:07.529 +So here's the BinDat syntax + +03:07.529 --> 03:10.490 +for the the previous specification. + +03:10.491 --> 03:11.610 +So here, for example, + +03:11.610 --> 03:16.970 +you see the case for a data packet + +03:16.970 --> 03:20.411 +which will have a 'type' field which is a byte + +03:20.411 --> 03:24.091 +(an unsigned 8-bit entity), + +03:24.091 --> 03:26.411 +then an 'opcode' which is also a byte, + +03:26.411 --> 03:30.731 +then a 'length' which is a 16-bit unsigned integer + +03:30.732 --> 03:34.092 +in little endian order, + +03:34.092 --> 03:38.732 +and then some 'id' for this entry, which is + +03:38.732 --> 03:43.531 +8 bytes containing a zero-terminated string, + +03:43.531 --> 03:47.531 +and then the actual data, basically the payload, + +03:47.532 --> 03:51.453 +which is in this case a vector of bytes, + +03:51.453 --> 03:54.812 +('bytes' here doesn't doesn't need to be specified) + +03:54.812 --> 03:58.172 +and here we specify the length of this vector. + +03:58.172 --> 03:59.773 +This 'length' here + +03:59.773 --> 04:02.252 +happens to be actually the name of THIS field, + +04:02.252 --> 04:03.853 +so the length of the data + +04:03.854 --> 04:06.574 +is specified by the 'length' field here, + +04:06.574 --> 04:08.574 +and BinDat will understand this part, + +04:08.574 --> 04:12.333 +which is the the nice part of BinDat. + +04:12.333 --> 04:15.774 +And then you have an alignment field at the end, + +04:15.774 --> 04:18.253 +which is basically padding. + +04:18.253 --> 04:20.574 +It says that it is padded + +04:20.575 --> 04:23.295 +until the next multiple of four. + +04:23.295 --> 04:25.855 +Okay. So this works reasonably well. + +04:25.855 --> 04:27.455 +This is actually very nice. + +04:27.455 --> 04:30.335 +With this, you can then call + +04:30.335 --> 04:32.975 +bindat-pack or bindat-unpack, + +04:32.975 --> 04:37.774 +passing it a string, or passing it an alist, + +04:37.774 --> 04:40.415 +to do the packing and unpacking. + +04:40.416 --> 04:43.296 +So, for example, if you take this string-- + +04:43.296 --> 04:45.856 +actually, in this case, it's a vector of bytes + +04:45.856 --> 04:49.456 +but it works the same; it works in both ways-- + +04:49.456 --> 04:53.536 +if you pass this to bindat-unpack, + +04:53.536 --> 04:57.456 +it will presumably return you this structure + +04:57.457 --> 05:00.017 +if you've given it the corresponding type. + +05:00.017 --> 05:01.776 +So it will extract-- + +05:01.776 --> 05:05.617 +you will see that there is an IP address, + +05:05.617 --> 05:08.017 +which is a destination IP, a source IP, + +05:08.017 --> 05:09.857 +and some port number, + +05:09.857 --> 05:12.977 +and some actual data here and there, etc. + +05:12.977 --> 05:18.017 +So this is quite convenient if you need to do this, + +05:18.018 --> 05:20.898 +and that's what it was designed for. + +05:20.898 --> 00:05:27.537 +So here we are. Let's go back to the actual talk. + +05:27.538 --> 05:34.338 +I converted BinDat to lexical scoping at some point + +05:34.339 --> 05:37.299 +and things seemed to work fine, + +05:37.299 --> 05:42.819 +except, at some point, probably weeks later, + +05:42.819 --> 05:47.139 +I saw a bug report + +05:47.139 --> 05:53.058 +about the new version using lexical scoping + +05:53.059 --> 05:56.339 +not working correctly with WeeChat. + +05:56.339 --> 06:00.580 +So here's the actual chunk of code + +06:00.580 --> 06:02.820 +that appears in WeeChat. + +06:02.820 --> 06:08.420 +Here you see that they also define a BinDat spec. + +06:08.421 --> 06:14.741 +It's a packet that has a 32-bit unsigned length, + +06:14.741 --> 06:18.500 +then some compression byte/compression information, + +06:18.500 --> 06:23.780 +then an id which contains basically another struct + +06:23.780 --> 06:26.901 +(which is specified elsewhere; doesn't matter here), + +06:26.902 --> 06:28.661 +and after that, a vector + +06:28.661 --> 06:33.382 +whose size is not just specified by 'length', + +06:33.382 --> 06:35.142 +but is computed from 'length'. + +06:35.142 --> 06:39.142 +So here's how they used to compute it in WeeChat. + +06:39.142 --> 06:42.822 +So the length here can be specified in BinDat. + +06:42.822 --> 06:43.941 +Instead of having + +06:43.942 --> 06:45.863 +just a reference to one of the fields, + +06:45.863 --> 06:48.903 +or having a constant, you can actually compute it, + +06:48.903 --> 06:52.502 +where you have to use this '(eval', + +06:52.502 --> 06:54.743 +and then followed by the actual expression + +06:54.743 --> 06:58.103 +where you say how you compute it. + +06:58.103 --> 07:01.463 +And here you see that it actually computes it + +07:01.464 --> 07:04.904 +based on the 'length of the structure -- + +07:04.904 --> 07:07.783 +that's supposed to be this 'length' field here -- + +07:07.783 --> 07:11.223 +and it's referred to using the bindat-get-field + +07:11.223 --> 07:14.503 +to extract the field from the variable 'struct'. + +07:14.503 --> 07:17.943 +And then it subtracts four, it subtracts one, + +07:17.943 --> 07:19.467 +and adds some other things + +07:19.468 --> 07:22.185 +which depend on some field + +07:22.185 --> 07:26.905 +that's found in this 'id' field here. + +07:26.905 --> 07:28.425 +And the problem with this code + +07:28.425 --> 07:30.425 +was that it broke + +07:30.425 --> 07:32.745 +because of this 'struct' variable here, + +07:32.745 --> 07:35.145 +because this 'struct' variable is not defined + +07:35.145 --> 07:38.105 +anywhere in the specification of BinDat. + +07:38.106 --> 07:41.866 +It was used internally as a local variable, + +07:41.866 --> 07:45.306 +and because it was using dynamic scoping, + +07:45.306 --> 07:47.386 +it actually happened to be available here, + +07:47.386 --> 07:50.826 +but the documentation nowhere specifies it. + +07:50.826 --> 07:52.506 +So it was not exactly + +07:52.506 --> 07:55.546 +a bug of the conversion to lexical scoping, + +07:55.547 --> 07:58.906 +but it ended up breaking this code. + +07:58.906 --> 08:01.226 +And there was no way to actually + +08:01.226 --> 08:05.066 +fix the code within the specification of BinDat. + +08:05.066 --> 08:08.287 +You had to go outside the specification of BinDat + +08:08.287 --> 08:10.427 +to fix this problem. + +08:10.427 --> 08:14.346 +This is basically how I started looking at BinDat. + +08:14.347 --> 08:17.808 +Then I went to actually investigate a bit more + +08:17.808 --> 08:19.627 +what was going on, + +08:19.627 --> 08:22.108 +and the thing I noticed along the way + +08:22.108 --> 08:25.787 +was basically that the specification of BinDat + +08:25.787 --> 08:29.528 +is fairly complex and has a lot of eval + +08:29.528 --> 08:30.748 +and things like this. + +08:30.749 --> 08:32.288 +So let's take a look + +08:32.288 --> 08:35.068 +at what the BinDat specification looks like. + +08:35.068 --> 08:36.589 +So here it's actually documented + +08:36.589 --> 08:40.269 +as a kind of grammar rules. + +08:40.269 --> 08:45.308 +A specification is basically a sequence of items, + +08:45.308 --> 08:47.389 +and then each of the items is basically + +08:47.389 --> 08:51.248 +a FIELD of a struct, so it has a FIELD name, + +08:51.249 --> 08:53.249 +and then a TYPE. + +08:53.249 --> 08:54.510 +Instead of a TYPE, + +08:54.510 --> 08:56.590 +it could have some other FORM for eval, + +08:56.590 --> 08:58.989 +which was basically never used as far as I know, + +08:58.989 --> 09:00.190 +or it can be some filler, + +09:00.190 --> 09:02.750 +or you can have some 'align' specification, + +09:02.750 --> 09:05.150 +or you can refer to another struct. + +09:05.150 --> 09:07.390 +It could also be some kind of union, + +09:07.391 --> 09:10.430 +or it can be some kind of repetition of something. + +09:10.430 --> 09:12.430 +And then you have the TYPE specified here, + +09:12.430 --> 09:18.271 +which can be some integers, strings, or a vector, + +09:18.271 --> 09:21.631 +and there are a few other special cases. + +09:21.631 --> 09:25.310 +And then the actual field itself + +09:25.311 --> 09:28.192 +can be either a NAME, or something that's computed, + +09:28.192 --> 09:30.752 +and then everywhere here, you have LEN, + +09:30.752 --> 00:09:32.480 +which specifies the length of vectors, + +00:09:32.480 --> 00:09:34.672 +for example, or length of strings. + +09:34.672 --> 09:37.632 +This is actually either nil to mean one, + +09:37.632 --> 09:39.072 +or it can be an ARG, + +09:39.072 --> 09:40.952 +where ARG is defined to be + +09:40.952 --> 09:42.672 +either an integer or DEREF, + +09:42.673 --> 09:46.673 +where DEREF is basically a specification + +09:46.673 --> 09:48.833 +that can refer, for example, to the 'length' field + +09:48.833 --> 09:51.956 +-- that's what we saw between parentheses: (length) + +09:51.956 --> 09:56.273 +was this way to refer to the 'length' field. + +09:56.273 --> 09:59.793 +Or it can be an expression, which is what we saw + +09:59.794 --> 10:02.834 +in the computation of the length for WeeChat, + +10:02.834 --> 10:04.914 +where you just had a '(eval' + +10:04.914 --> 10:06.334 +and then some computation + +10:06.334 --> 10:10.274 +of the length of the payload. + +10:10.274 --> 10:12.354 +And so if you look here, you see that + +10:12.354 --> 10:14.674 +it is fairly large and complex, + +10:14.674 --> 10:18.514 +and it uses eval everywhere. And actually, + +10:18.515 --> 10:20.675 +it's not just that it has eval in its syntax, + +10:20.675 --> 10:23.395 +but the implementation has to use eval everywhere, + +10:23.395 --> 10:25.314 +because, if you go back + +10:25.314 --> 10:27.475 +to see the kind of code we see, + +10:27.475 --> 10:29.538 +we see here we just define + +10:29.538 --> 10:34.195 +weechat--relay-message-spec as a constant! + +10:34.195 --> 10:37.314 +It's nothing than just data, right? + +10:37.315 --> 10:38.836 +So within this data + +10:38.836 --> 10:41.076 +there are things we need to evaluate, + +10:41.076 --> 10:42.356 +but it's pure data, + +10:42.356 --> 10:44.356 +so it will have to be evaluated + +10:44.356 --> 10:46.596 +by passing it to eval. It can't be compiled, + +10:46.596 --> 10:50.196 +because it's within a quote, right? + +10:50.196 --> 10:52.836 +And so for that reason, kittens really + +10:52.837 --> 10:55.956 +suffer terribly with uses of BinDat. + +10:55.956 --> 10:59.957 +You really have to be very careful with that. + +10:59.957 --> 11:02.037 +More seriously, + +11:02.037 --> 11:05.157 +the 'struct' variable was not documented, + +11:05.157 --> 11:07.797 +and yet it's indispensable + +11:07.797 --> 11:08.996 +for important applications, + +11:08.996 --> 11:11.157 +such as using in WeeChat. + +11:11.158 --> 11:13.078 +So clearly this needs to be fixed. + +11:13.078 --> 11:15.481 +Of course, we can just document 'struct' + +11:15.481 --> 11:18.038 +as some variable that's used there, + +11:18.038 --> 11:19.798 +but of course we don't want to do that, + +11:19.798 --> 11:23.398 +because 'struct' is not obviously + +11:23.398 --> 11:25.398 +a dynamically scoped variable, + +11:25.398 --> 11:29.317 +so it's not very clean. + +11:29.318 --> 11:31.939 +Also other problems I noticed was that the grammar + +11:31.939 --> 11:35.239 +is significantly more complex than necessary. + +11:35.239 --> 11:38.199 +We have nine distinct non-terminals. + +11:38.199 --> 11:39.639 +There is ambiguity. + +11:39.639 --> 11:44.919 +If you try to use a field whose name is 'align', + +11:44.919 --> 11:48.679 +or 'fill', or something like this, + +11:48.680 --> 11:50.920 +then it's going to be misinterpreted, + +11:50.920 --> 11:54.920 +or it can be misinterpreted. + +11:54.920 --> 11:58.760 +The vector length can be either an expression, + +11:58.760 --> 12:02.280 +or an integer, or a reference to a label, + +12:02.280 --> 12:03.720 +but the expression + +12:03.720 --> 12:06.360 +should already be the general case, + +12:06.361 --> 12:08.041 +and this expression can itself be + +12:08.041 --> 12:09.401 +just a constant integer, + +12:09.401 --> 12:13.961 +so this complexity is probably not indispensable, + +12:13.961 --> 12:15.641 +or it could be replaced with something simpler. + +12:15.641 --> 12:17.401 +That's what I felt like. + +12:17.401 --> 12:19.161 +And basically lots of places + +12:19.161 --> 12:21.721 +allow an (eval EXP) form somewhere + +12:21.721 --> 12:25.081 +to open up the door for more flexibility, + +12:25.082 --> 12:26.922 +but not all of them do, + +12:26.922 --> 12:29.482 +and we don't really want + +12:29.482 --> 12:31.001 +to have this eval there, right? + +12:31.001 --> 12:33.802 +It's not very convenient syntactically either. + +12:33.802 --> 12:36.042 +So it makes the uses of eval + +12:36.042 --> 12:38.362 +a bit heavier than they need to be, + +12:38.362 --> 12:41.722 +and so I didn't really like this part. + +12:41.723 --> 12:42.603 +Another part is that + +12:42.603 --> 12:45.183 +when I tried to figure out what was going on, + +12:45.183 --> 12:46.666 +[dog barks and distracts Stefan] + +12:46.666 --> 12:50.043 +I had trouble... Winnie as well, as you can hear. + +12:50.043 --> 12:50.923 +She had trouble as well. + +12:50.923 --> 12:53.083 +But one of the troubles was that + +12:53.083 --> 12:55.002 +there was no way to debug the code + +12:55.002 --> 12:57.562 +via Edebug, because it's just data, + +12:57.562 --> 13:00.523 +so Edebug doesn't know that it has to look at it + +13:00.524 --> 13:02.683 +and instrument it. + +13:02.683 --> 13:05.644 +And of course it was not conveniently extensible. + +13:05.644 --> 13:07.164 +That's also one of the things + +13:07.164 --> 13:08.487 +I noticed along the way. + +13:09.084 --> 13:12.844 +Okay, so here's an example of + +13:12.844 --> 13:15.484 +problems not that I didn't just see there, + +13:15.485 --> 13:18.684 +but that were actually present in code. + +13:18.684 --> 13:22.124 +I went to look at code that was using BinDat + +13:22.124 --> 13:24.285 +to see what uses looked like, + +13:24.285 --> 13:28.765 +and I saw that BinDat was not used very heavily, + +13:28.765 --> 13:30.365 +but some of the main uses + +13:30.365 --> 13:33.884 +were just to read and write integers. + +13:33.885 --> 13:37.565 +And here you can see a very typical case. + +13:37.565 --> 13:41.726 +This is also coming from WeeChat. + +13:41.726 --> 13:43.565 +We do a bindat-get-field + +13:43.565 --> 13:48.445 +of the length of some struct we read. + +13:48.445 --> 13:50.685 +Actually, the struct we read is here. + +13:50.685 --> 13:51.646 +It has a single field, + +13:51.647 --> 13:53.006 +because the only thing we want to do + +13:53.006 --> 13:56.287 +is actually to unpack a 32-bit integer, + +13:56.287 --> 13:58.287 +but the only way we can do that + +13:58.287 --> 14:01.647 +is by specifying a struct with one field. + +14:01.647 --> 14:04.847 +And so we have to extract this struct of one field, + +14:04.847 --> 14:07.246 +which constructs an alist + +14:07.246 --> 14:09.647 +containing the actual integer, + +14:09.648 --> 14:11.887 +and then we just use get-field to extract it. + +14:11.887 --> 14:15.007 +So this doesn't seem very elegant + +14:15.007 --> 14:16.528 +to have to construct an alist + +14:16.528 --> 14:20.368 +just to then extract the integer from it. + +14:20.368 --> 14:21.648 +Same thing if you try to pack it: + +14:21.648 --> 14:25.007 +you first have to construct the alist + +14:25.007 --> 14:31.247 +to pass it to bindat-pack unnecessarily. + +14:31.248 --> 14:33.248 +Another problem that I saw in this case + +14:33.248 --> 14:35.729 +(it was in the websocket package) + +14:35.729 --> 14:39.568 +was here, where they actually have a function + +14:39.568 --> 14:41.169 +where they need to write + +14:41.169 --> 14:43.888 +an integer of a size that will vary + +14:43.888 --> 14:45.888 +depending on the circumstances. + +14:45.889 --> 14:49.650 +And so they have to test the value of this integer, + +14:49.650 --> 14:52.210 +and depending on which one it is, + +14:52.210 --> 14:54.449 +they're going to use different types. + +14:54.449 --> 14:56.290 +So here it's a case + +14:56.290 --> 14:59.490 +where we want to have some kind of way to eval -- + +14:59.490 --> 15:02.530 +to compute the length of the integer -- + +15:02.531 --> 15:08.130 +instead of it being predefined or fixed. + +15:08.130 --> 15:10.211 +So this is one of the cases + +15:10.211 --> 15:16.531 +where the lack of eval was a problem. + +15:16.531 --> 15:20.051 +And actually in all of websocket, + +15:20.051 --> 15:22.611 +BinDat is only used to pack and unpack integers, + +15:22.612 --> 15:24.612 +even though there are many more opportunities + +15:24.612 --> 15:26.772 +to use BinDat in there. + +15:26.772 --> 15:29.331 +But it's not very convenient to use BinDat, + +15:29.331 --> 00:15:35.890 +as it stands, for those other cases. + +15:35.891 --> 15:39.732 +So what does the new design look like? + +15:39.733 --> 15:44.132 +Well in the new design, here's the problematic code + +15:44.132 --> 15:46.373 +for WeeChat. + +15:46.373 --> 15:49.012 +So we basically have the same fields as before, + +15:49.012 --> 15:50.853 +you just see that instead of u32, + +15:50.853 --> 15:53.733 +we now have 'uint 32' separately. + +15:53.733 --> 15:55.332 +The idea is that now this 32 + +15:55.332 --> 15:59.093 +can be an expression you can evaluate, + +15:59.094 --> 16:04.054 +and so the u8 is also replaced by 'uint 8', + +16:04.054 --> 16:07.253 +and the id type is basically the same as before, + +16:07.253 --> 16:08.854 +and here another difference we see, + +16:08.854 --> 16:11.654 +and the main difference... + +16:11.654 --> 16:13.494 +Actually, it's the second main difference. + +16:13.494 --> 16:15.174 +The first main difference is that + +16:15.175 --> 16:18.694 +we don't actually quote this whole thing. + +16:18.694 --> 16:23.095 +Instead, we pass it to the bindat-type macro. + +16:23.095 --> 16:25.095 +So this is a macro + +16:25.095 --> 16:27.574 +that's going to actually build the type. + +16:27.574 --> 16:29.254 +This is a big difference + +16:29.254 --> 16:30.535 +in terms of performance also, + +16:30.535 --> 16:32.694 +because by making it a macro, + +16:32.695 --> 16:34.296 +we can pre-compute the code + +16:34.296 --> 16:37.255 +that's going to pack and unpack this thing, + +16:37.255 --> 16:38.936 +instead of having to interpret it + +16:38.936 --> 16:41.096 +every time we pack and unpack. + +16:41.096 --> 16:43.815 +So this macro will generate more efficient code + +16:43.815 --> 16:45.815 +along the way. + +16:45.815 --> 16:48.695 +Also it makes the code that appears in here + +16:48.695 --> 16:50.296 +visible to the compiler + +16:50.297 --> 16:54.617 +because we can give an Edebug spec for it. + +16:54.617 --> 16:57.497 +And so here as an argument to vec, + +16:57.497 --> 16:59.016 +instead of having to specify + +16:59.016 --> 17:00.937 +that this is an evaluated expression, + +17:00.937 --> 17:02.777 +we just write the expression directly, + +17:02.777 --> 17:05.096 +because all the expressions that appear there + +17:05.096 --> 17:07.417 +will just be evaluated, + +17:07.418 --> 17:11.418 +and we don't need to use the 'struct' variable + +17:11.418 --> 17:14.137 +and then extract the length field from it. + +17:14.137 --> 17:16.938 +We can just use length as a variable. + +17:16.938 --> 17:18.698 +So this variable 'length' here + +17:18.698 --> 17:20.778 +will refer to this field here, + +17:20.778 --> 17:23.578 +and then this variable 'id' here + +17:23.578 --> 17:25.897 +will refer to this field here, + +17:25.898 --> 17:27.738 +and so we can just use the field values + +17:27.738 --> 17:30.459 +as local variables, which is very natural + +17:30.459 --> 00:17:31.679 +and very efficient also, + +00:17:31.679 --> 00:17:34.618 +because the code would actually directly do that, + +17:34.618 --> 17:37.899 +and the code that unpacks those data + +17:37.899 --> 17:40.299 +will just extract an integer + +17:40.299 --> 17:42.219 +and bind it to the length variable, + +17:42.219 --> 17:47.579 +and so that makes it immediately available there. + +17:47.580 --> 17:51.340 +Okay, let's see also + +17:51.340 --> 17:54.220 +what the actual documentation looks like. + +17:54.220 --> 17:57.739 +And so if we look at the doc of BinDat, + +17:57.739 --> 18:01.180 +we see the actual specification of the grammar. + +18:01.181 --> 18:03.181 +And so here we see instead of having + +18:03.181 --> 18:06.461 +these nine different non-terminals, + +18:06.461 --> 18:08.061 +we basically have two: + +18:08.061 --> 18:10.781 +we have the non-terminal for TYPE, + +18:10.781 --> 18:15.021 +which can be either a uint, a uintr, or a string, + +18:15.021 --> 18:17.421 +or bits, or fill, or align, or vec, + +18:17.421 --> 18:19.901 +or those various other forms; + +18:19.902 --> 18:22.621 +or it can be a struct, in which case, + +18:22.621 --> 18:23.981 +in the case of struct, + +18:23.981 --> 18:27.502 +then it will be followed by a sequence -- + +18:27.502 --> 18:30.142 +a list of FIELDs, where each of the FIELDs + +18:30.142 --> 18:33.902 +is basically a LABEL followed by another TYPE. + +18:33.902 --> 18:37.342 +And so this makes the whole specification + +18:37.343 --> 18:39.823 +much simpler. We don't have any distinction now + +18:39.823 --> 18:42.862 +between struct being a special case, + +18:42.862 --> 18:46.383 +as opposed to just the normal types. + +18:46.383 --> 18:49.263 +struct is just now one of the possible types + +18:49.263 --> 18:52.543 +that can appear here. + +18:52.543 --> 18:53.263 +The other thing is that + +18:53.263 --> 18:55.742 +the LABEL is always present in the structure, + +18:55.743 --> 18:58.384 +so there's no ambiguity. + +18:58.384 --> 19:00.304 +Also all the above things, + +19:00.304 --> 19:03.103 +like the BITLEN we have here, + +19:03.103 --> 19:04.384 +the LEN we have here, + +19:04.384 --> 19:07.504 +the COUNT for vector we have here, + +19:07.504 --> 19:10.224 +these are all plain Elisp expressions, + +19:10.224 --> 19:13.024 +so they are implicitly evaluated if necessary. + +19:13.025 --> 19:14.705 +If you want them to be constant, + +19:14.705 --> 19:16.705 +and really constant, you can just use quotes, + +19:16.705 --> 19:20.145 +for those rare cases where it's necessary. + +19:20.145 --> 19:21.905 +Another thing is that you can extend it + +19:21.905 --> 19:25.505 +with with bindat-defmacro. + +19:25.505 --> 19:30.225 +Okay, let's go back here. + +19:30.226 --> 19:32.706 +So what are the advantages of this approach? + +19:32.706 --> 19:34.625 +As I said, one of the main advantages + +19:34.625 --> 19:39.346 +is that we now have support for Edebug. + +19:39.346 --> 19:41.426 +We don't have 'struct', 'repeat', and 'align' + +19:41.426 --> 19:42.946 +as special cases anymore. + +19:42.946 --> 19:44.625 +These are just normal types. + +19:44.625 --> 19:48.066 +Before, there was uint as type, int as type, + +19:48.067 --> 19:49.267 +and those kinds of things. + +19:49.267 --> 19:51.110 +'struct' and 'repeat' and 'align' + +19:51.110 --> 19:53.267 +were in a different case. + +19:53.267 --> 19:54.387 +So there were + +19:54.387 --> 19:56.787 +some subtle differences between those + +19:56.787 --> 19:59.027 +that completely disappeared. + +19:59.027 --> 20:02.626 +Also in the special cases, there was 'union', + +20:02.626 --> 20:05.027 +and union now has completely disappeared. + +20:05.027 --> 20:07.827 +We don't need it anymore, because instead, + +20:07.828 --> 20:09.588 +we can actually use code anywhere. + +20:09.588 --> 20:11.908 +That's one of the things I didn't mention here, + +20:11.908 --> 20:17.268 +but in this note here, + +20:17.268 --> 20:19.747 +that's one of the important notes. + +20:19.747 --> 20:21.987 +Not only are BITLEN, LEN, COUNT etc. + +20:21.987 --> 20:23.028 +Elisp expressions, + +20:23.028 --> 20:26.788 +but the type itself -- any type itself -- + +20:26.789 --> 20:29.029 +is basically an expression. + +20:29.029 --> 20:32.709 +And so you can, instead of having 'uint BITLEN', + +20:32.709 --> 20:36.628 +you can have '(if blah-blah-blah uint string)', + +20:36.628 --> 20:38.149 +and so you can have a field + +20:38.149 --> 20:40.549 +that can be either string or an int, + +20:40.549 --> 20:44.789 +depending on some condition. + +20:44.790 --> 20:46.869 +And for that reason we don't need a union. + +20:46.869 --> 20:47.910 +Instead of having a union, + +20:47.910 --> 20:50.710 +we can just have a 'cond' or a 'pcase' + +20:50.710 --> 20:53.590 +that will return the type we want to use, + +20:53.590 --> 20:55.109 +depending on the context, + +20:55.109 --> 21:00.950 +which will generally depend on some previous field. + +21:00.951 --> 21:03.750 +Also we don't need to use single-field structs + +21:03.750 --> 21:05.351 +for simple types anymore, + +21:05.351 --> 21:09.271 +because there's no distinction between struct + +21:09.271 --> 21:11.271 +and other types. + +21:11.271 --> 21:17.191 +So we can pass to bindat-pack and bindat-unpack + +21:17.191 --> 21:20.951 +a specification which just says "here's an integer" + +21:20.952 --> 21:24.392 +and we'll just pack and unpack the integer. + +21:24.392 --> 21:26.472 +And of course now all the code is exposed, + +21:26.472 --> 21:29.192 +so not only Edebug works, but also Flymake, + +21:29.192 --> 21:30.392 +and the compiler, etc. -- + +21:30.392 --> 21:33.111 +they can complain about it, + +21:33.111 --> 21:38.871 +and give you warnings and errors as we like them. + +21:38.872 --> 21:44.553 +And of course the kittens are much happier. + +21:44.553 --> 21:48.153 +Okay. This is going a bit over time, + +21:48.153 --> 00:21:51.272 +so let's try to go faster. + +21:51.273 --> 21:53.752 +Here are some of the new features + +21:53.753 --> 21:54.794 +that are introduced. + +21:54.794 --> 21:56.314 +I already mentioned briefly + +21:56.314 --> 22:00.633 +that you can define new types with bindat-defmacro. + +22:00.633 --> 22:04.474 +that's one of the important novelties, + +22:04.474 --> 22:08.794 +and you can extend BinDat with new types this way. + +22:08.794 --> 22:10.714 +The other thing you can do is + +22:10.714 --> 22:16.233 +you can control how values or packets + +22:16.234 --> 22:20.315 +are unpacked, and how they are represented. + +22:20.315 --> 22:22.555 +In the old BinDat, + +22:22.555 --> 22:24.315 +the packet is necessarily represented, + +22:24.315 --> 22:28.634 +when you unpack it, as an alist, basically, + +22:28.635 --> 22:30.396 +or a struct becomes an alist, + +22:30.396 --> 22:31.676 +and that's all there is. + +22:31.676 --> 22:34.076 +You don't have any choice about it. + +22:34.076 --> 22:35.596 +With the new system, + +22:35.596 --> 22:38.076 +by default, it also returns just an alist, + +22:38.076 --> 22:41.916 +but you can actually control what it's unpacked as, + +22:41.916 --> 22:46.396 +or what it's packed from, using these keywords. + +22:46.396 --> 22:49.596 +With :unpack-val, you can give an expression + +22:49.597 --> 22:53.357 +that will construct the unpacked value + +22:53.357 --> 22:56.957 +from the various fields. + +22:56.957 --> 22:59.197 +And with :pack-val and :pack-var, + +22:59.197 --> 23:02.557 +you can specify how to extract the information + +23:02.557 --> 23:05.116 +from the unpacked value + +23:05.117 --> 00:23:08.077 +to generate the pack value. + +23:08.078 --> 23:12.637 +So here are some examples. + +23:12.637 --> 23:15.358 +Here's an example taken from osc. + +23:15.358 --> 23:17.438 +osc actually doesn't use BinDat currently, + +23:17.438 --> 23:22.478 +but I have played with it + +23:22.479 --> 23:23.758 +to see what it would look like + +23:23.758 --> 23:26.159 +if we were to use BinDat. + +23:26.159 --> 23:28.638 +So here's the definition + +23:28.638 --> 23:30.638 +of the timetag representation, + +23:30.638 --> 23:35.279 +which represents timestamps in osc. + +23:35.279 --> 23:37.998 +So you would use bindat-type + +23:37.998 --> 23:40.559 +and then you have here :pack-var + +23:40.559 --> 23:42.080 +basically gives a name + +23:42.080 --> 23:48.559 +when we try to pack a timestamp. + +23:48.559 --> 23:51.520 +'time' will be the variable whose name contains + +23:51.520 --> 23:54.159 +the actual timestamp we will receive. + +23:54.159 --> 23:57.520 +So we want to represent the unpacked value + +23:57.520 --> 24:00.240 +as a normal Emacs timestamp, + +24:00.240 --> 24:02.480 +and then basically convert from this timestamp + +24:02.480 --> 24:06.401 +to a string, or from a string to this timestamp. + +24:06.401 --> 24:10.080 +When we receive it, it will be called time, + +24:10.080 --> 24:12.240 +so we can refer to it, + +24:12.240 --> 24:15.360 +and so in order to actually encode it, + +24:15.360 --> 24:18.320 +we basically turn this timestamp into an integer -- + +24:18.320 --> 24:20.799 +that's what this :pack-val does. + +24:20.799 --> 24:23.442 +It says when we try to pack it, + +24:23.442 --> 24:26.082 +here's the the value that we should use. + +24:26.082 --> 24:27.760 +We turn it into an integer, + +24:27.760 --> 24:30.320 +and then this integer is going to be encoded + +24:30.320 --> 24:36.162 +as a uint 64-bit. So a 64-bit unsigned integer. + +24:36.163 --> 24:38.960 +When we try to unpack the value, + +24:38.960 --> 24:40.720 +this 'ticks' field + +24:40.720 --> 24:45.679 +will contain an unsigned int of 64 bits. + +24:45.679 --> 24:50.559 +We want to return instead a timestamp -- + +24:50.559 --> 24:53.924 +a time value -- from Emacs. + +24:53.924 --> 24:59.363 +Here we use the representation of time + +24:59.363 --> 25:02.799 +as a pair of number of ticks + +25:02.799 --> 25:06.720 +and the corresponding frequency of those ticks. + +25:06.720 --> 25:09.120 +So that's what we do here with :unpack-val, + +25:09.120 --> 25:12.004 +which is construct the cons corresponding to it. + +25:12.004 --> 25:16.400 +With this definition, bindat-pack/unpack + +25:16.400 --> 00:25:19.039 +are going to convert to and from + +00:25:19.039 --> 00:25:21.760 +proper time values on one side, + +25:21.760 --> 25:26.159 +and binary strings on the other. + +25:26.159 --> 25:27.520 +Note, of course, + +25:27.520 --> 25:30.320 +that I complained that the old BinDat + +25:30.320 --> 25:36.080 +had to use single-field structs for simple types, + +25:36.080 --> 25:37.039 +and here, basically, + +25:37.039 --> 25:39.840 +I'm back using single-field structs as well + +25:39.840 --> 25:41.120 +for this particular case -- + +25:41.120 --> 25:44.640 +actually a reasonably frequent case, to be honest. + +25:44.640 --> 25:49.279 +But at least this is not so problematic, + +25:49.279 --> 25:51.840 +because we actually control what is returned, + +25:51.840 --> 25:54.159 +so even though it's a single-field struct, + +25:54.159 --> 25:56.640 +it's not going to construct an alist + +25:56.640 --> 25:58.320 +or force you to construct an alist. + +25:58.320 --> 26:02.720 +Instead, it really receives and takes a value + +26:02.720 --> 26:07.367 +in the ideal representation that we chose. + +26:07.367 --> 26:10.007 +Here we have a more complex example, + +26:10.007 --> 26:12.488 +where the actual type is recursive, + +26:12.488 --> 26:18.640 +because it's representing those "LEB"... + +26:18.640 --> 26:20.400 +I can't remember what "LEB" stands for, + +26:20.400 --> 26:22.559 +but it's a representation + +26:22.559 --> 26:25.600 +for arbitrary length integers, + +26:25.600 --> 26:27.520 +where basically + +26:27.520 --> 26:33.360 +every byte is either smaller than 128, + +26:33.360 --> 26:36.799 +in which case it's the end of the of the value, + +26:36.799 --> 26:39.760 +or it's a value bigger than 128, + +26:39.760 --> 26:42.159 +in which case there's an extra byte on the end + +26:42.159 --> 26:44.490 +that's going to continue. + +26:44.490 --> 26:46.640 +Here we see the representation + +26:46.640 --> 26:52.240 +is basically a structure that starts with a byte, + +26:52.240 --> 26:53.679 +which contains this value, + +26:53.679 --> 26:56.000 +which can be either the last value or not, + +26:56.000 --> 26:59.770 +and the tail, which will either be empty, + +26:59.770 --> 27:01.279 +or contain something else. + +27:01.279 --> 27:04.000 +The empty [case] is here; + +27:04.000 --> 27:07.039 +if the head value is smaller than 128, + +27:07.039 --> 27:11.840 +then the type of this tail is going to be (unit 0), + +27:11.840 --> 27:16.492 +so basically 'unit' is the empty type, + +27:16.492 --> 27:20.880 +and 0 is the value we will receive when we read it. + +27:20.880 --> 27:25.520 +And if not, then it has as type 'loop', + +27:25.520 --> 27:28.240 +which is the type we're defining, + +27:28.240 --> 27:30.491 +so it's the recursive case, + +27:30.491 --> 27:35.132 +where then the rest of the type is the type itself. + +27:35.132 --> 27:37.120 +And so this lets us pack and unpack. + +27:37.120 --> 27:39.600 +We pass it an arbitrary size integer, + +27:39.600 --> 27:42.240 +and it's going to turn it into + +27:42.240 --> 27:48.492 +this LEB128 binary representation, and vice versa. + +27:48.492 --> 27:52.480 +I have other examples if you're interested, + +27:52.480 --> 00:27:56.093 +but anyway, here's the conclusion. + +27:56.094 --> 27:58.320 +We have a simpler, more flexible, + +27:58.320 --> 28:01.039 +and more powerful BinDat now, + +28:01.039 --> 28:03.454 +which is also significantly faster. + +28:03.454 --> 28:06.799 +And I can't remember the exact speed-up, + +28:06.799 --> 28:08.720 +but it's definitely not a few percents. + +28:08.720 --> 28:12.640 +I vaguely remember about 4x faster in my tests, + +28:12.640 --> 28:16.815 +but it's probably very different in different cases + +28:16.815 --> 28:20.159 +so it might be just 4x, 2x -- who knows? + +28:20.159 --> 28:23.374 +Try it for yourself, but I was pretty pleased, + +28:23.374 --> 00:28:28.335 +because it wasn't the main motivation, so anyway... + +28:28.336 --> 28:31.135 +The negatives are here. + +28:31.135 --> 28:34.480 +In the new system, there's this bindat-defmacro + +28:34.480 --> 28:36.720 +which lets us define, kind of, new types, + +28:36.720 --> 28:40.895 +and bindat-type also lets us define new types, + +28:40.895 --> 28:45.360 +and the distinction between them is a bit subtle; + +28:45.360 --> 28:48.080 +it kind of depends on... + +28:48.080 --> 28:50.880 +well it has an impact on efficiency + +28:50.880 --> 28:53.520 +more than anything, so it's not very satisfactory. + +28:53.520 --> 28:56.737 +There's a bit of redundancy between the two. + +28:56.737 --> 28:59.039 +There is no bit-level control, just as before. + +28:59.039 --> 29:02.097 +We can only manipulate basically bytes. + +29:02.098 --> 29:03.360 +So this is definitely not usable + +29:03.360 --> 29:09.058 +for a Huffman encoding kind of thing. + +29:09.058 --> 29:10.880 +Also, it's not nearly as flexible + +29:10.880 --> 29:12.240 +as some of the alternatives. + +29:12.240 --> 29:13.760 +So you know GNU Poke + +29:13.760 --> 29:20.017 +has been a vague inspiration for this work, + +29:20.018 --> 29:22.480 +and GNU Poke gives you a lot more power + +29:22.480 --> 29:25.059 +in how to specify the types, etc. + +29:25.059 --> 29:26.579 +And of course one of the main downsides + +29:26.579 --> 29:28.018 +is that it's still not used very much. + +29:28.018 --> 29:29.283 +Actually, the new BinDat + +29:29.283 --> 29:31.039 +is not used by any package + +29:31.039 --> 29:33.059 +as far as I know right now, + +29:33.059 --> 29:35.279 +but even the old one is not used very often, + +29:35.279 --> 29:36.799 +so who knows + +29:36.799 --> 29:38.799 +whether it's actually going to + +29:38.799 --> 29:41.520 +work very much better or not? + +29:41.520 --> 29:44.399 +Anyway, this is it for this talk. + +29:44.399 --> 29:46.683 +Thank you very much.

-00:51.680 --> 00:00:54.879 -able to modify itself while running - -00:54.879 --> 00:00:56.640 -um so you shouldn't be static and you - -00:56.640 --> 00:00:59.280 -shouldn't never restart for - -00:59.280 --> 00:01:01.359 -any reason like in engineering max you - -01:01.359 --> 00:01:03.280 -can't predefine every function or every - -01:03.280 --> 00:01:05.680 -functionality the way you want - -01:05.680 --> 00:01:09.360 -and extensibility should not be limited - -01:09.360 --> 00:01:11.040 -with this i mean that if you add a new - -01:11.040 --> 00:01:12.560 -package shouldn't be a difference you - -01:12.560 --> 00:01:14.960 -shouldn't have an api - -01:14.960 --> 00:01:18.560 -to extend the software and the entire uh - -01:18.560 --> 00:01:20.640 -software itself should be the external - -01:20.640 --> 00:01:22.640 -api code - -01:22.640 --> 00:01:25.360 -i'll argue that's also - -01:25.360 --> 00:01:26.640 -um - -01:26.640 --> 00:01:28.320 -should be list base - -01:28.320 --> 00:01:29.759 -but - -01:29.759 --> 00:01:32.880 -um it's controversial so - -01:32.880 --> 00:01:34.720 -yes they're going to get this definition - -01:34.720 --> 00:01:37.280 -and then extend upon it so - -01:37.280 --> 00:01:38.880 -bear with me - -01:38.880 --> 00:01:41.920 -so right now uh genuine max is the best - -01:41.920 --> 00:01:44.079 -emacs that we have that's not the only - -01:44.079 --> 00:01:46.320 -one uh - -01:46.320 --> 00:01:48.479 -not even the first one imax but it's the - -01:48.479 --> 00:01:49.680 -best one that we have the one that we're - -01:49.680 --> 00:01:51.759 -using the one that we that i'm using - -01:51.759 --> 00:01:54.079 -right now and the one that we're here - -01:54.079 --> 00:01:55.280 -for - -01:55.280 --> 00:01:57.759 -but as we all know it's not perfect i'm - -01:57.759 --> 00:01:59.759 -going to highlight some - -01:59.759 --> 00:02:02.479 -um imperfection that all that we should - -02:02.479 --> 00:02:05.119 -know i guess that you must have - -02:05.119 --> 00:02:07.360 -so the first one is that uh i would - -02:07.360 --> 00:02:09.440 -argue that inmate lisp is a good lisp - -02:09.440 --> 00:02:11.280 -but it's not a general purpose - -02:11.280 --> 00:02:13.280 -programming language - -02:13.280 --> 00:02:15.040 -you can do pretty crazy things with - -02:15.040 --> 00:02:16.959 -emacs but i will argue that you can do - -02:16.959 --> 00:02:18.400 -also do that with - -02:18.400 --> 00:02:20.640 -brain [ __ ] i'm not comparing them i know - -02:20.640 --> 00:02:22.239 -with my list so much better than brain - -02:22.239 --> 00:02:24.720 -[ __ ] but that's not an argument in - -02:24.720 --> 00:02:26.480 -mclisp it's - -02:26.480 --> 00:02:29.599 -a language for an editor - -02:29.599 --> 00:02:32.080 -not for writing - -02:32.080 --> 00:02:34.720 -game engine for example - -02:34.720 --> 00:02:37.040 -um it's not the fastest lisp we all know - -02:37.040 --> 00:02:40.239 -this is um - -02:40.239 --> 00:02:42.319 -not in the middle i will say was really - -02:42.319 --> 00:02:44.720 -slow now it's getting better maybe with - -02:44.720 --> 00:02:46.480 -the c integration - -02:46.480 --> 00:02:49.200 -um thanks to andrea it can be even - -02:49.200 --> 00:02:51.680 -better but we'll see and has limited - -02:51.680 --> 00:02:55.360 -concurrency this will still be the case - -02:55.360 --> 00:02:58.159 -it has shared threats first i know - -02:58.159 --> 00:03:00.000 -it's not perfect and it's also not that - -03:00.000 --> 00:03:01.040 -fast - -03:01.040 --> 00:03:03.360 -and even though this for some people is - -03:03.360 --> 00:03:04.480 -not an issue - -03:04.480 --> 00:03:06.080 -i'll argue that for me it's an issue - -03:06.080 --> 00:03:07.920 -which is the canoe emac score is written - -03:07.920 --> 00:03:09.840 -in the c - -03:09.840 --> 00:03:13.519 -um i'm not a big fan of c i mean i have - -03:13.519 --> 00:03:15.519 -wrote things about c in the past and - -03:15.519 --> 00:03:16.840 -it's - -03:16.840 --> 00:03:20.560 -okay as a language but um i prefer i'll - -03:20.560 --> 00:03:22.800 -be in lisp so i can hack on it easily - -03:22.800 --> 00:03:24.720 -and really find it while it's running - -03:24.720 --> 00:03:27.440 -all in just one language so you don't - -03:27.440 --> 00:03:29.920 -have to learn two languages to get into - -03:29.920 --> 00:03:30.959 -it - -03:30.959 --> 00:03:33.120 -um even though it's just ten percent of - -03:33.120 --> 00:03:35.599 -emacs right but still there needs to be - -03:35.599 --> 00:03:38.799 -maintained and yeah - -03:38.799 --> 00:03:41.120 -i don't like that uh kind of uh a max - -03:41.120 --> 00:03:43.040 -aspect but just - -03:43.040 --> 00:03:45.360 -this was just my opinion okay so while - -03:45.360 --> 00:03:46.720 -you're like you know mac's pretty good - -03:46.720 --> 00:03:48.400 -you should use it - -03:48.400 --> 00:03:50.319 -you probably use it if you're here and - -03:50.319 --> 00:03:53.280 -use it every day it's great - -03:53.280 --> 00:03:54.239 -so - -03:54.239 --> 00:03:56.560 -some people in the past - -03:56.560 --> 00:03:58.080 -wanted to write - -03:58.080 --> 00:04:00.480 -an e-max of course and not the emacs - -04:00.480 --> 00:04:02.400 -and they think about different things - -04:02.400 --> 00:04:04.799 -and they attempt to write similar emacs - -04:04.799 --> 00:04:07.680 -like things i'm going to um - -04:07.680 --> 00:04:09.519 -i know there's a lot of more way more - -04:09.519 --> 00:04:12.879 -emacs than the one i'm going to say now - -04:12.879 --> 00:04:16.000 -but i just going to - -04:16.000 --> 00:04:18.639 -focus on the emacs that uh meets the - -04:18.639 --> 00:04:20.639 -criteria are not like - -04:20.639 --> 00:04:23.280 -uh the linux turbo's emacs right which - -04:23.280 --> 00:04:24.479 -is just a c - -04:24.479 --> 00:04:28.400 -simple e max to write c for me that may - -04:28.400 --> 00:04:30.160 -be uh - -04:30.160 --> 00:04:32.400 -an e max for the people but not for me i - -04:32.400 --> 00:04:34.639 -wouldn't argue that that's not - -04:34.639 --> 00:04:36.720 -really an emacs just an editor with - -04:36.720 --> 00:04:38.560 -commands similar to imax - -04:38.560 --> 00:04:40.160 -but - -04:40.160 --> 00:04:43.120 -i digress okay so the language i will - -04:43.120 --> 00:04:45.120 -argue that common lisp may be the best - -04:45.120 --> 00:04:46.320 -language - -04:46.320 --> 00:04:47.759 -period - -04:47.759 --> 00:04:49.600 -sorry about that the best language for - -04:49.600 --> 00:04:51.520 -writing emacs also - -04:51.520 --> 00:04:53.759 -um it's a timeless standard reaching in - -04:53.759 --> 00:04:57.520 -the 1990s is fast and reliable - -04:57.520 --> 00:05:00.160 -it's a great lisp i will argue that the - -05:00.160 --> 00:05:01.840 -best lisp but i don't want to get any - -05:01.840 --> 00:05:03.280 -trouble so i would just say it's great - -05:03.280 --> 00:05:04.400 -lisp - -05:04.400 --> 00:05:06.880 -um has good library support doesn't have - -05:06.880 --> 00:05:08.720 -like a huge library like i would say - -05:08.720 --> 00:05:12.160 -python or c but pretty - -05:12.160 --> 00:05:14.800 -robust and good library - -05:14.800 --> 00:05:18.000 -similar to mclisp which may seem as a - -05:18.000 --> 00:05:21.120 -historical accident which maybe it is - -05:21.120 --> 00:05:23.919 -but also in this case has some - -05:23.919 --> 00:05:26.160 -interesting properties that will - -05:26.160 --> 00:05:29.280 -be discussed - -05:29.280 --> 00:05:30.960 -later - -05:30.960 --> 00:05:32.400 -okay so - -05:32.400 --> 00:05:33.600 -um - -05:33.600 --> 00:05:35.280 -taking common lisps a language to write - -05:35.280 --> 00:05:36.479 -an imax i'm going to get some - -05:36.479 --> 00:05:37.759 -technologies in documentation that we - -05:37.759 --> 00:05:40.720 -can use to write an e-max in common lisp - -05:40.720 --> 00:05:43.440 -so the first one is mcclaim which is an - -05:43.440 --> 00:05:45.039 -implementation of a - -05:45.039 --> 00:05:47.120 -common lisp interface standard - -05:47.120 --> 00:05:50.320 -this is great i mean i loved how - -05:50.320 --> 00:05:52.720 -this is written how it is defined i like - -05:52.720 --> 00:05:54.479 -standard things - -05:54.479 --> 00:05:57.440 -um mclean it's a marvelous tool i will - -05:57.440 --> 00:05:59.759 -argue that it's the best - -05:59.759 --> 00:06:01.280 -um toolkit - -06:01.280 --> 00:06:03.039 -i wouldn't say there's a toolkit because - -06:03.039 --> 00:06:05.360 -it's way more extense than it but it's - -06:05.360 --> 00:06:07.919 -great i would highly recommend if you - -06:07.919 --> 00:06:10.639 -want to write a gui application in - -06:10.639 --> 00:06:14.400 -common lisp well mcclain is great - -06:14.400 --> 00:06:18.400 -also some people thought about - -06:18.400 --> 00:06:20.160 -libraries for writing emac style - -06:20.160 --> 00:06:22.720 -application so to create an emacs some - -06:22.720 --> 00:06:24.720 -people already thought about this and - -06:24.720 --> 00:06:26.479 -wrote a paper - -06:26.479 --> 00:06:27.440 -um - -06:27.440 --> 00:06:29.840 -one of them was robert strand - -06:29.840 --> 00:06:32.319 -which is the guy more interested in in - -06:32.319 --> 00:06:34.880 -imax like things - -06:34.880 --> 00:06:36.479 -and this paper is great you can get a - -06:36.479 --> 00:06:37.759 -lot of information how you can write - -06:37.759 --> 00:06:39.360 -your application get - -06:39.360 --> 00:06:41.039 -similar functionality and all the things - -06:41.039 --> 00:06:43.600 -that i said before - -06:43.600 --> 00:06:45.840 -and also the same - -06:45.840 --> 00:06:47.039 -of the - -06:47.039 --> 00:06:49.199 -robert strand or the guys that wrote - -06:49.199 --> 00:06:52.240 -that paper also wrote clefo which is - -06:52.240 --> 00:06:54.479 -a library for text editor buffer but - -06:54.479 --> 00:06:57.599 -more important it's also a definition - -06:57.599 --> 00:06:59.599 -so this video - -06:59.599 --> 00:07:02.639 -out there will where he explains - -07:02.639 --> 00:07:03.599 -um - -07:03.599 --> 00:07:05.919 -what clapper is so he wrote an - -07:05.919 --> 00:07:08.479 -implementation of clover but it's more - -07:08.479 --> 00:07:12.000 -of like a - -07:12.000 --> 00:07:12.880 -um - -07:12.880 --> 00:07:14.400 -yeah - -07:14.400 --> 00:07:17.599 -like a standard like a way to write - -07:17.599 --> 00:07:20.639 -uh how buffers or work in emacs - -07:20.639 --> 00:07:23.280 -and i think it's better - -07:23.280 --> 00:07:25.599 -in some ways that what imac genuine mac - -07:25.599 --> 00:07:26.960 -does right now - -07:26.960 --> 00:07:29.039 -um in other ways it's really interesting - -07:29.039 --> 00:07:31.759 -and i just have had a lot of fun - -07:31.759 --> 00:07:33.360 -implementing it so - -07:33.360 --> 00:07:35.919 -i'm using it more or less - -07:35.919 --> 00:07:38.080 -uh so yeah that's some great - -07:38.080 --> 00:07:40.479 -documentation great foundation so you - -07:40.479 --> 00:07:42.080 -don't have to - -07:42.080 --> 00:07:43.599 -i mean it's - -07:43.599 --> 00:07:44.879 -really - -07:44.879 --> 00:07:46.319 -interesting to write everything by - -07:46.319 --> 00:07:48.080 -yourself because you are - -07:48.080 --> 00:07:49.120 -a great - -07:49.120 --> 00:07:51.440 -programmer and you you want to have - -07:51.440 --> 00:07:52.879 -control of everything i understand - -07:52.879 --> 00:07:54.800 -everything from the ground up but we - -07:54.800 --> 00:07:56.720 -have to understand that - -07:56.720 --> 00:07:58.879 -an imax it's a really complex - -07:58.879 --> 00:08:00.639 -application - -08:00.639 --> 00:08:01.759 -and - -08:01.759 --> 00:08:03.120 -i will say that if you have some - -08:03.120 --> 00:08:05.520 -foundation it will be easier and you - -08:05.520 --> 00:08:08.479 -don't have to rewrite the wheel 20 times - -08:08.479 --> 00:08:10.080 -right - -08:10.080 --> 00:08:12.720 -okay so attempts uh the same guy robert - -08:12.720 --> 00:08:13.680 -strand - -08:13.680 --> 00:08:16.879 -have two climax which is emacs and emacs - -08:16.879 --> 00:08:19.360 -like thing written in common lisp - -08:19.360 --> 00:08:21.599 -um the first ones the third one is - -08:21.599 --> 00:08:23.360 -abandon and the second one is a work in - -08:23.360 --> 00:08:24.840 -progress - -08:24.840 --> 00:08:27.039 -um it's really interesting the second - -08:27.039 --> 00:08:29.440 -one uses in fact the clefor buffer - -08:29.440 --> 00:08:32.159 -implementation one question - -08:32.159 --> 00:08:36.880 -and the first one is just a mcclaim um - -08:36.880 --> 00:08:39.200 -front end remax so it's really tight the - -08:39.200 --> 00:08:40.800 -so the the - -08:40.800 --> 00:08:42.959 -interface retired with the api so it's - -08:42.959 --> 00:08:44.880 -basically i'm sickly - -08:44.880 --> 00:08:48.320 -um software that's similar to an emacs - -08:48.320 --> 00:08:49.360 -right - -08:49.360 --> 00:08:51.760 -and the third one it's a lem project - -08:51.760 --> 00:08:54.240 -which is a common lisp editor that aims - -08:54.240 --> 00:08:56.320 -to be really close to remax and it - -08:56.320 --> 00:08:59.519 -probably fits the criteria but - -08:59.519 --> 00:09:01.600 -and uses the encourages for the - -09:01.600 --> 00:09:03.279 -interface for as i know and it's really - -09:03.279 --> 00:09:05.200 -commonly focused so it even has some - -09:05.200 --> 00:09:08.560 -major modes for other languages but - -09:08.560 --> 00:09:09.839 -i mean it's - -09:09.839 --> 00:09:11.279 -um - -09:11.279 --> 00:09:13.440 -it's mainly for common lisp written by - -09:13.440 --> 00:09:15.680 -common lisp and for common list - -09:15.680 --> 00:09:18.080 -developers - -09:18.080 --> 00:09:21.839 -um so i decided to write my own emacs - -09:21.839 --> 00:09:23.839 -but i don't want to write everything - -09:23.839 --> 00:09:25.680 -from scratch - -09:25.680 --> 00:09:28.720 -because i'm not a creator programmer - -09:28.720 --> 00:09:29.839 -and also because probably there's - -09:29.839 --> 00:09:33.040 -something that some people already tried - -09:33.040 --> 00:09:34.640 -and the first thing i noticed with all - -09:34.640 --> 00:09:36.480 -these attempts - -09:36.480 --> 00:09:38.959 -that they fail in compete with emacs so - -09:38.959 --> 00:09:41.920 -to say they don't have an imax conf - -09:41.920 --> 00:09:43.839 -and they don't support genuine max - -09:43.839 --> 00:09:45.440 -packages - -09:45.440 --> 00:09:46.880 -and that's a big deal because they're - -09:46.880 --> 00:09:49.519 -more of the thousands packages out there - -09:49.519 --> 00:09:51.040 -under great - -09:51.040 --> 00:09:53.120 -and imagine they want to convince - -09:53.120 --> 00:09:54.800 -someone to say hey try this editor - -09:54.800 --> 00:09:57.440 -instead of x thing - -09:57.440 --> 00:09:59.839 -i would say okay can i use git things so - -09:59.839 --> 00:10:02.079 -i have to write a git - -10:02.079 --> 00:10:02.959 -um - -10:02.959 --> 00:10:04.640 -liar - -10:04.640 --> 00:10:07.360 -maggot or mode and i want to play tetris - -10:07.360 --> 00:10:09.440 -the other road so that's - -10:09.440 --> 00:10:10.640 -really - -10:10.640 --> 00:10:12.640 -hard for one person to do - -10:12.640 --> 00:10:14.079 -so someone - -10:14.079 --> 00:10:16.240 -thought similar so they say okay i'm - -10:16.240 --> 00:10:18.079 -going to rewrite the maxi aph common - -10:18.079 --> 00:10:19.200 -lisp - -10:19.200 --> 00:10:21.440 -it was this is what back in 2005 by sol - -10:21.440 --> 00:10:22.399 -bets - -10:22.399 --> 00:10:24.000 -sabits - -10:24.000 --> 00:10:26.000 -but it was banjo in 2007. the project - -10:26.000 --> 00:10:27.600 -was called lice - -10:27.600 --> 00:10:28.640 -and - -10:28.640 --> 00:10:31.600 -it was a really interesting approach - -10:31.600 --> 00:10:34.880 -um it wasn't finished and it was lost in - -10:34.880 --> 00:10:35.920 -time - -10:35.920 --> 00:10:37.440 -so my idea was to continue with the - -10:37.440 --> 00:10:38.880 -project so the foundation was really - -10:38.880 --> 00:10:40.320 -interesting even though i didn't like - -10:40.320 --> 00:10:42.160 -some other - -10:42.160 --> 00:10:43.760 -designing choices - -10:43.760 --> 00:10:45.360 -um but i want to continue with projects - -10:45.360 --> 00:10:47.519 -finished you cannot see emacs api add a - -10:47.519 --> 00:10:49.839 -compatibility layer to use canoe max - -10:49.839 --> 00:10:52.000 -packages that's the selling point right - -10:52.000 --> 00:10:53.760 -so you don't have to - -10:53.760 --> 00:10:56.000 -use new things - -10:56.000 --> 00:10:57.839 -i like my emacs i just want to have my - -10:57.839 --> 00:11:00.560 -emacs with commodities that's it and - -11:00.560 --> 00:11:02.959 -also better probably a better buffer - -11:02.959 --> 00:11:05.519 -implementation so the idea now that uh - -11:05.519 --> 00:11:07.839 -having an imaginativity layer - -11:07.839 --> 00:11:10.320 -is there improving e-max upon it right - -11:10.320 --> 00:11:13.040 -you can use the e-max api or the new one - -11:13.040 --> 00:11:14.880 -depending on your needs - -11:14.880 --> 00:11:15.760 -you can also have that that - -11:15.760 --> 00:11:19.120 -compatibility of both - -11:19.120 --> 00:11:21.920 -so um i come up with cedar - -11:21.920 --> 00:11:25.839 -um cedar is my attempt is a nice - -11:25.839 --> 00:11:27.120 -fork - -11:27.120 --> 00:11:30.079 -i will say the hug for hard fork because - -11:30.079 --> 00:11:32.399 -i change um - -11:32.399 --> 00:11:35.200 -a lot of things and add a lot of things - -11:35.200 --> 00:11:37.519 -but it's similar still similar - -11:37.519 --> 00:11:38.320 -um - -11:38.320 --> 00:11:39.680 -and for this demo i'm going to use the - -11:39.680 --> 00:11:41.839 -cidar and courses branch we want to test - -11:41.839 --> 00:11:44.880 -it out because the other ones are a work - -11:44.880 --> 00:11:46.560 -in progress so one - -11:46.560 --> 00:11:48.079 -it's the mclean - -11:48.079 --> 00:11:49.519 -club for implementation which is not - -11:49.519 --> 00:11:51.360 -finished and doesn't run - -11:51.360 --> 00:11:54.560 -and the other one is with the visual - -11:54.560 --> 00:11:54.959 -that's to explain here but basically - -11:54.959 --> 00:11:57.200 -and debugger - -11:57.200 --> 00:11:59.600 -it's an interesting debugger similar to - -11:59.600 --> 00:12:01.839 -slime - -12:01.839 --> 00:12:04.560 -which is the superior lisp - -12:04.560 --> 00:12:07.279 -for re max let's begin with max so it's - -12:07.279 --> 00:12:12.079 -increases base also like um - -12:12.079 --> 00:12:13.760 -like limb - -12:13.760 --> 00:12:16.959 -but um way more easy simple - -12:16.959 --> 00:12:19.279 -um i - -12:19.279 --> 00:12:22.880 -write well i translate more or less this - -12:22.880 --> 00:12:24.560 -list mode functionality - -12:24.560 --> 00:12:26.079 -and it has similar - -12:26.079 --> 00:12:28.079 -genuine max api - -12:28.079 --> 00:12:29.600 -we'll see that in the demo - -12:29.600 --> 00:12:31.600 -um it's usable but i work in progress - -12:31.600 --> 00:12:33.279 -instead of functionality right now i'm - -12:33.279 --> 00:12:35.279 -not focusing on stability yet i'm - -12:35.279 --> 00:12:38.240 -focusing finish the mclean front end - -12:38.240 --> 00:12:41.120 -which i'm not even halfway there - -12:41.120 --> 00:12:42.720 -but i hope to finish it - -12:42.720 --> 00:12:45.519 -maybe next year who knows - -12:45.519 --> 00:12:46.959 -finish the compatibility layer from the - -12:46.959 --> 00:12:48.399 -new max packages i seen this i think - -12:48.399 --> 00:12:50.959 -this is doable i know how to do it i - -12:50.959 --> 00:12:52.639 -just need time - -12:52.639 --> 00:12:53.600 -maybe - -12:53.600 --> 00:12:55.760 -a little bit of caffeine - -12:55.760 --> 00:12:57.040 -coffee - -12:57.040 --> 00:12:59.279 -so uh let's go with the demo right - -12:59.279 --> 00:13:02.079 -so uh let's open terminal what's this - -13:02.079 --> 00:13:04.800 -anchor base let's go to quick lisp - -13:04.800 --> 00:13:06.800 -log there - -13:06.800 --> 00:13:11.279 -um and let's run it - -13:11.279 --> 00:13:13.760 -okay so now that we're here um it give - -13:13.760 --> 00:13:16.000 -us the welcome thing this is the main - -13:16.000 --> 00:13:17.519 -buffer it's like we'll say the emacs - -13:17.519 --> 00:13:19.200 -buffer when you enter - -13:19.200 --> 00:13:21.040 -um so we know that it's firming this is - -13:21.040 --> 00:13:22.800 -not hardcoded - -13:22.800 --> 00:13:25.040 -okay and now we see it's a major mode in - -13:25.040 --> 00:13:27.200 -the bottom right lisp - -13:27.200 --> 00:13:29.360 -it's lisp interaction and - -13:29.360 --> 00:13:32.880 -this is the name of the buffer right - -13:32.880 --> 00:13:35.600 -um okay so we have a couple of buffers - -13:35.600 --> 00:13:38.240 -we have scratch which is the fundamental - -13:38.240 --> 00:13:40.720 -mode and messages all right - -13:40.720 --> 00:13:42.399 -okay so - -13:42.399 --> 00:13:44.639 -let's get some interesting things first - -13:44.639 --> 00:13:46.399 -uh let's open a file - -13:46.399 --> 00:13:48.959 -so i think it's in - -13:48.959 --> 00:13:51.199 -programming - -13:51.199 --> 00:13:53.440 -a max - -13:53.440 --> 00:13:56.480 -conf 2021 and let's go to c there - -13:56.480 --> 00:13:58.079 -let's go to demo - -13:58.079 --> 00:14:00.000 -so let's open a file so - -14:00.000 --> 00:14:01.440 -um - -14:01.440 --> 00:14:03.040 -phone lock is not yet - -14:03.040 --> 00:14:04.399 -um - -14:04.399 --> 00:14:06.240 -well it's implemented so it's there but - -14:06.240 --> 00:14:07.920 -it's not active by default - -14:07.920 --> 00:14:09.680 -so let's open - -14:09.680 --> 00:14:11.360 -uh mx - -14:11.360 --> 00:14:13.600 -and let's go lisp - -14:13.600 --> 00:14:16.079 -interaction mode - -14:16.079 --> 00:14:17.279 -right - -14:17.279 --> 00:14:19.199 -so this when you show me here is the - -14:19.199 --> 00:14:21.680 -implementation of the kill sex sex - -14:21.680 --> 00:14:24.240 -express s expression command - -14:24.240 --> 00:14:28.880 -which is exactly the same point by point - -14:28.880 --> 00:14:31.279 -from the emacs one you can go right now - -14:31.279 --> 00:14:32.959 -umax and ask - -14:32.959 --> 00:14:35.279 -how is skills s expression defined this - -14:35.279 --> 00:14:36.480 -is the same - -14:36.480 --> 00:14:38.560 -and this is how you define a key so we - -14:38.560 --> 00:14:41.920 -have we can say uh describe - -14:41.920 --> 00:14:43.839 -symbol - -14:43.839 --> 00:14:46.399 -the package will be - -14:46.399 --> 00:14:48.399 -cedar and the symbol is - -14:48.399 --> 00:14:50.480 -global map - -14:50.480 --> 00:14:51.610 -global map - -14:51.610 --> 00:14:53.279 -[Applause] - -14:53.279 --> 00:14:54.240 -so - -14:54.240 --> 00:14:56.160 -it's a top level global keymap - -14:56.160 --> 00:14:58.480 -thank you for the information - -14:58.480 --> 00:15:02.160 -um but you can also say okay uh can i - -15:02.160 --> 00:15:05.120 -say okay - -15:05.120 --> 00:15:08.000 -global map - -15:08.000 --> 00:15:10.079 -okay i'll be giving this a key map so - -15:10.079 --> 00:15:11.600 -even though i want to aim to have the - -15:11.600 --> 00:15:12.480 -same - -15:12.480 --> 00:15:15.920 -um api the - -15:15.920 --> 00:15:17.760 -um sorry - -15:17.760 --> 00:15:20.079 -uh the back thing so the back end is - -15:20.079 --> 00:15:22.480 -going to be class oriented and not same - -15:22.480 --> 00:15:24.720 -any max but the return expression should - -15:24.720 --> 00:15:27.680 -be really similar so if we say current - -15:27.680 --> 00:15:29.759 -buffer - -15:29.759 --> 00:15:31.759 -it will give us the buffer it's not the - -15:31.759 --> 00:15:33.759 -same in emacs but it's a buffer object - -15:33.759 --> 00:15:35.519 -and we can also ask - -15:35.519 --> 00:15:37.519 -about let me try to remember - -15:37.519 --> 00:15:39.440 -oh there we are - -15:39.440 --> 00:15:40.639 -um - -15:40.639 --> 00:15:41.839 -but for - -15:41.839 --> 00:15:45.680 -name we can close this and open one here - -15:45.680 --> 00:15:48.079 -and we can say okay so we have this - -15:48.079 --> 00:15:48.959 -thing - -15:48.959 --> 00:15:50.959 -that will give us the name so uh this is - -15:50.959 --> 00:15:52.800 -similar to the emacs api - -15:52.800 --> 00:15:54.399 -as we saw we - -15:54.399 --> 00:15:55.120 -so - -15:55.120 --> 00:15:57.519 -briefly we have a lot a couple of - -15:57.519 --> 00:15:58.639 -commands - -15:58.639 --> 00:16:00.240 -um - -16:00.240 --> 00:16:02.160 -kills expression also have a little bit - -16:02.160 --> 00:16:03.759 -of - -16:03.759 --> 00:16:06.639 -help kill word kill line - -16:06.639 --> 00:16:07.680 -region - -16:07.680 --> 00:16:08.959 -kill buffer - -16:08.959 --> 00:16:11.440 -all things that we expect from emacs - -16:11.440 --> 00:16:12.800 -um - -16:12.800 --> 00:16:14.320 -and yeah this is there's a couple of - -16:14.320 --> 00:16:16.160 -things i may show but i think this is - -16:16.160 --> 00:16:18.320 -good enough i don't have enough time if - -16:18.320 --> 00:16:20.720 -you want more information - -16:20.720 --> 00:16:22.800 -so let's go back to it let's close the - -16:22.800 --> 00:16:25.680 -buffer does it work no it doesn't work - -16:25.680 --> 00:16:28.079 -okay now the head buffer no ah let's go - -16:28.079 --> 00:16:29.920 -to cedar - -16:29.920 --> 00:16:32.320 -okay so if you want more information - -16:32.320 --> 00:16:32.870 -um - -16:32.870 --> 00:16:34.399 -[Applause] - -16:34.399 --> 00:16:36.880 -first of all thank you very much um - -16:36.880 --> 00:16:39.040 -sorry i don't have enough time to show -

00:00:33.250 +for static and integrated Emacs tools. -00:27.039 --> 00:00:29.679 -into the repo and these other lines here +00:00:33.350 --> 00:00:35.367 +And to understand better what -00:29.679 --> 00:00:33.200 -are tests for these lines +00:00:35.467 --> 00:00:37.650 +CLEDE is, one first has to understand -00:33.200 --> 00:00:35.120 -there's a lot of information here so let +00:00:37.750 --> 00:00:40.133 +the base that I use... -00:35.120 --> 00:00:40.480 -me organize them in a more visual way +00:00:40.233 --> 00:00:43.767 +so the foundation that I use for CLEDE. -00:40.480 --> 00:00:42.960 -this is our file in lua +00:00:43.867 --> 00:00:46.050 +Um, so it is CEDET-- -00:42.960 --> 00:00:45.760 -lua sees this thing as a as a multi-line +00:00:46.150 --> 00:00:47.417 +and specifically Semantic-- -00:45.760 --> 00:00:47.760 -comment but we are going to see it as a +00:00:47.517 --> 00:00:49.733 +so we first have to talk about and -00:47.760 --> 00:00:51.920 -test block and eev mode is active and so +00:00:49.833 --> 00:00:50.417 +understand what it is. -00:51.920 --> 00:00:54.480 -f8 does the right thing +00:00:50.517 --> 00:00:53.817 +So CEDET is a collection -00:54.480 --> 00:00:57.360 -uh these three lines here set up the +00:00:53.917 --> 00:00:55.183 +of Emacs development environment tools. -00:57.360 --> 00:01:00.079 -target buffer running a lower apple you +00:00:55.283 --> 00:00:57.233 +It was created by Eric Ludlam -01:00.079 --> 00:01:03.520 -can see the the prompt of the rebel here +00:00:57.333 --> 00:01:00.767 +(I hope to say that name right) -01:03.520 --> 00:01:05.360 -and these lines here are sent to the +00:01:00.867 --> 00:01:02.333 +in the late 90s, and -01:05.360 --> 00:01:07.200 -rebel +00:01:02.433 --> 00:01:04.833 +the idea was to create entire IDE for Emacs. -01:07.200 --> 00:01:09.680 -and when we type f8 on the line that +00:01:04.933 --> 00:01:10.433 +CEDET is still integrated into Emacs, -01:09.680 --> 00:01:10.720 -starts +00:01:10.533 --> 00:01:11.717 +and it has a lot of interesting things -01:10.720 --> 00:01:13.600 -with the red star like these lines here +00:01:11.817 --> 00:01:14.033 +that are not used for too many people, -01:13.600 --> 00:01:15.759 -what if it does is that it sends the +00:01:14.133 --> 00:01:16.167 +so I'm going to explain some of those. -01:15.759 --> 00:01:18.240 -rest of the line sorry it +00:01:16.267 --> 00:01:18.417 +First, let's go with the good ones that -01:18.240 --> 00:01:21.119 -executes the rest of the line as lisp +00:01:18.517 --> 00:01:21.233 +one that I use for CLEDE and that can -01:21.119 --> 00:01:23.920 -so it executes the three effects here +00:01:21.333 --> 00:01:23.167 +be used for other projects as well. -01:23.920 --> 00:01:26.240 -executes these lines as lisp and they +00:01:23.267 --> 00:01:28.450 +Some of the features that -01:26.240 --> 00:01:29.520 -set up the target buffer here +00:01:28.550 --> 00:01:32.450 +CEDET has is parse generators -01:29.520 --> 00:01:31.759 -and when we type f8 on the line that +00:01:32.550 --> 00:01:35.217 +so we have Wisent and Bovine. -01:31.759 --> 00:01:34.159 -does not start with the red star +00:01:35.317 --> 00:01:38.350 +Wisent is basically a Bison clone -01:34.159 --> 00:01:36.640 -the f8 sends the line to the target +00:01:38.450 --> 00:01:40.200 +that was written in Emacs Lisp -01:36.640 --> 00:01:38.799 -buffer and moves down +00:01:40.300 --> 00:01:43.117 +that you can also specify grammars. -01:38.799 --> 00:01:41.040 -and this line loads this file under +00:01:43.217 --> 00:01:45.617 +It's a really big and rather complex -01:41.040 --> 00:01:45.200 -apple and these lines are tests +00:01:45.717 --> 00:01:47.350 +tool to work with, -01:45.200 --> 00:01:47.520 -so we just saw how to use an existing +00:01:47.450 --> 00:01:49.183 +and it's secretly used for, as far as -01:47.520 --> 00:01:50.000 -test block let's now see how to create a +00:01:49.283 --> 00:01:51.667 +I know, two languages. -01:50.000 --> 00:01:52.640 -new test block we just have to run this +00:01:51.767 --> 00:01:53.317 +They're not also well supported, -01:52.640 --> 00:01:55.680 -meta x e insert test block +00:01:53.417 --> 00:01:55.317 +but we'll get into that later. -01:55.680 --> 00:01:58.079 -or meta x euat +00:01:55.417 --> 00:01:58.133 +Also Bovine, which is a way more -01:58.079 --> 00:02:01.439 -and the result depends on the major mode +00:01:58.233 --> 00:01:59.867 +simple tool, like you can... -02:01.439 --> 00:02:03.920 -uh let's see let's understand that that +00:01:59.967 --> 00:02:01.733 +you don't need grammar files, -02:03.920 --> 00:02:06.079 -by looking at the source code +00:02:01.833 --> 00:02:07.350 +you can write just in plain Emacs Lisp. -02:06.079 --> 00:02:08.720 -eeit is an alias to this function here +00:02:07.450 --> 00:02:10.917 +And you also have utilities to work with -02:08.720 --> 00:02:10.640 -and this function is just five lines of +00:02:11.017 --> 00:02:16.550 +those generated tag trees, so to say. -02:10.640 --> 00:02:12.800 -code plus a dot string +00:02:16.650 --> 00:02:23.533 +These are not AST parsers like real Bison; -02:12.800 --> 00:02:14.560 -and the dot string explains that if the +00:02:23.633 --> 00:02:25.617 +they are tag-based so they basically get -02:14.560 --> 00:02:16.480 -major mode is full mode then this +00:02:25.717 --> 00:02:27.533 +tags and extract information from them, -02:16.480 --> 00:02:18.800 -function tries to call +00:02:27.633 --> 00:02:30.083 +and I can use that information -02:18.800 --> 00:02:21.360 -a function called e insert test plot +00:02:30.183 --> 00:02:31.000 +with Emacs Lisp -02:21.360 --> 00:02:24.800 -test full mode if that function exists +00:02:31.000 --> 00:02:33.567 +to contextually understand better -02:24.800 --> 00:02:27.280 -and that if that function does not exist +00:02:33.667 --> 00:02:36.267 +the language that you're parsing, -02:27.280 --> 00:02:29.680 -then it yields an error +00:02:36.367 --> 00:02:37.083 +but in general, -02:29.680 --> 00:02:32.080 -and here's an example of one such +00:02:37.183 --> 00:02:40.083 +this decision was made (as far as I know) -02:32.080 --> 00:02:34.239 -function that's a function that +00:02:40.183 --> 00:02:43.217 +because of the Emacs Lisp -02:34.239 --> 00:02:37.280 -inserts a test block in haskell mode +00:02:43.317 --> 00:02:44.217 +limitation of the time. -02:37.280 --> 00:02:40.319 -and here we can see two functions like +00:02:44.317 --> 00:02:50.233 +So Emacs was a rather -02:40.319 --> 00:02:42.480 -this one for haskell mode and one for +00:02:50.333 --> 00:02:52.167 +slower Lisp-- slow Lisp-- -02:42.480 --> 00:02:46.080 -javascript mode +00:02:52.267 --> 00:02:55.850 +so they decide to just use -02:46.080 --> 00:02:48.560 -uh these functions look quite similar +00:02:55.950 --> 00:02:58.750 +tag-based thing instead of a parse-- -02:48.560 --> 00:02:49.440 -but +00:02:58.850 --> 00:03:02.333 +I mean-- an AST-based one. -02:49.440 --> 00:02:52.720 -their effects look quite different +00:03:02.433 --> 00:03:05.167 +And Semantic give you some utility with -02:52.720 --> 00:02:55.760 -to make this comparison here i started +00:03:05.267 --> 00:03:06.250 +that as Senator, for example, give you -02:55.760 --> 00:02:57.280 -by writing +00:03:06.350 --> 00:03:07.667 +some semantic navigation. -02:57.280 --> 00:02:59.680 -by creating seven files each one in a +00:03:07.767 --> 00:03:09.750 +So CEDET is way more than this, -02:59.680 --> 00:03:01.120 -different language +00:03:09.850 --> 00:03:12.433 +but this is not a CEDET talk. -03:01.120 --> 00:03:03.040 -and initially each one of these files +00:03:12.533 --> 00:03:13.983 +So if you want to get more information, -03:03.040 --> 00:03:04.959 -only had a comment with the name of the +00:03:14.083 --> 00:03:16.350 +you can go to the official webpage. -03:04.959 --> 00:03:08.239 -language so c haskell javascript org +00:03:16.450 --> 00:03:19.933 +I have to say that it is outdated, and -03:08.239 --> 00:03:10.560 -mode etc +00:03:20.033 --> 00:03:22.933 +Emacs changed some things over the years -03:10.560 --> 00:03:13.040 -and in each one of these files i typed +00:03:23.033 --> 00:03:24.067 +because CEDET was merged into Emacs -03:13.040 --> 00:03:16.959 -meta x eeit to insert the test block +00:03:24.167 --> 00:03:27.767 +in 2011, as far as I know. -03:16.959 --> 00:03:18.800 -so here we can see that these test +00:03:27.867 --> 00:03:30.417 +You can also go to the official Emacs -03:18.800 --> 00:03:20.319 -blocks are different +00:03:30.517 --> 00:03:32.883 +documentation (the manual), which will get -03:20.319 --> 00:03:22.080 -for example the syntax for multi-line +00:03:32.983 --> 00:03:35.317 +more information about every tool, -03:22.080 --> 00:03:24.000 -comments is different depending on the +00:03:35.417 --> 00:03:38.317 +but it's a really interesting thing, and -03:24.000 --> 00:03:25.200 -language +00:03:38.417 --> 00:03:40.883 +I'm really sad that it is forgotten. -03:25.200 --> 00:03:27.760 -uh this block here that selects which +00:03:40.983 --> 00:03:43.233 +So let's go with the bad things: -03:27.760 --> 00:03:30.319 -rebel to run is also different +00:03:43.333 --> 00:03:46.483 +that CEDET is an abandoned project. -03:30.319 --> 00:03:33.200 -this line here that shows how that +00:03:46.583 --> 00:03:48.217 +This has some benefits like it's not -03:33.200 --> 00:03:34.879 -tells the repo to +00:03:48.317 --> 00:03:50.550 +going to change that much, -03:34.879 --> 00:03:37.680 -load the current file is also different +00:03:50.650 --> 00:03:52.367 +but it's, of course, not ideal. -03:37.680 --> 00:03:39.680 -depending on the language +00:03:52.467 --> 00:03:56.833 +Most of the tooling that CEDET -03:39.680 --> 00:03:41.840 -in some cases i had to improvise a bit +00:03:56.933 --> 00:03:58.100 +have right now are surpassed -03:41.840 --> 00:03:43.360 -for example +00:03:58.200 --> 00:03:59.633 +by other packages. -03:43.360 --> 00:03:46.400 -uh to implement test blocks in shell +00:03:59.733 --> 00:04:02.650 +And at first, I know Eric was working -03:46.400 --> 00:03:48.560 -mode i had to use this +00:04:02.750 --> 00:04:07.467 +with C at the time so he totally has -03:48.560 --> 00:03:52.560 -this with syntax using a rear document +00:04:07.567 --> 00:04:10.533 +"real support" so you can use CEDET -03:52.560 --> 00:03:55.280 -in tcl i also had to improvise a bit and +00:04:10.633 --> 00:04:13.033 +for other languages, but -03:55.280 --> 00:03:57.840 -in some cases i had to improvise a lot +00:04:13.133 --> 00:04:15.383 +to work really like an IDE, more or less, -03:57.840 --> 00:04:01.120 -for example in org mode there isn't an +00:04:15.483 --> 00:04:17.017 +it's all the... -04:01.120 --> 00:04:03.360 -obvious rebel to run and there isn't an +00:04:17.117 --> 00:04:19.517 +C is the only language supported, -04:03.360 --> 00:04:05.280 -obvious way to load the +00:04:19.617 --> 00:04:21.667 +and maybe some simple C++, but that's it. -04:05.280 --> 00:04:08.080 -the current org file into the repo so +00:04:21.767 --> 00:04:24.017 +It needs more documentation. -04:08.080 --> 00:04:11.680 -the default action of meta x eeit +00:04:24.117 --> 00:04:25.683 +People really don't know how to use it -04:11.680 --> 00:04:14.400 -in log mode is just to insert this thing +00:04:25.783 --> 00:04:28.583 +because, I have to say, rather complex -04:14.400 --> 00:04:15.439 -here +00:04:28.683 --> 00:04:30.067 +to get a project working with it, -04:15.439 --> 00:04:17.519 -that we can use to run a +00:04:30.167 --> 00:04:33.717 +and then make use of Semantic -04:17.519 --> 00:04:22.320 -shell in a rebel +00:04:33.817 --> 00:04:36.667 +because [it] needs some maintenance and -04:22.320 --> 00:04:23.199 -so +00:04:36.767 --> 00:04:38.567 +to update the code. -04:23.199 --> 00:04:25.680 -these functions are quite similar and in +00:04:38.667 --> 00:04:41.083 +But I will argue that even with these -04:25.680 --> 00:04:27.440 -the beginning i was writing all of them +00:04:41.183 --> 00:04:44.383 +deficiencies, it's usable, and -04:27.440 --> 00:04:29.680 -by hand but then i got bored and i wrote +00:04:44.483 --> 00:04:47.517 +I use the foundation of base for -04:29.680 --> 00:04:32.320 -a function to help you write functions +00:04:47.617 --> 00:04:49.533 +parse infrastructure for other languages. -04:32.320 --> 00:04:33.840 -like that +00:04:49.633 --> 00:04:52.367 +I will say that with Common Lisp was -04:33.840 --> 00:04:35.759 -this function is called +00:04:52.467 --> 00:04:53.983 +rather easy because -04:35.759 --> 00:04:38.080 -find e-uit-links and it creates a +00:04:54.083 --> 00:04:56.033 +CEDET already have Emacs Lisp parser -04:38.080 --> 00:04:39.919 -temporary buffer +00:04:56.133 --> 00:04:57.900 +even though it's not great. -04:39.919 --> 00:04:41.680 -and the contents of this temporary +00:04:58.000 --> 00:05:00.483 +It's easy to adapt and to use. -04:41.680 --> 00:04:43.440 -buffer depends on the major mode for +00:05:00.583 --> 00:05:04.000 +It's not used in an Emacs -04:43.440 --> 00:04:45.680 -example if the current mode is python +00:05:04.100 --> 00:05:05.433 +right now because, well, -04:45.680 --> 00:04:48.880 -mode then running this function here +00:05:05.533 --> 00:05:08.883 +Emacs know very well itself, -04:48.880 --> 00:04:51.840 -creates a temporary buffer that lets me +00:05:08.983 --> 00:05:11.600 +but it's there. -04:51.840 --> 00:04:53.840 -write the support for +00:05:11.700 --> 00:05:17.583 +So these, of course, are static parsers -04:53.840 --> 00:04:56.880 -test blocks into python mode or rewrite +00:05:17.683 --> 00:05:19.517 +so you don't need to run any -04:56.880 --> 00:04:59.040 -the function that supports test blocks +00:05:19.617 --> 00:05:21.883 +other language-specific tools, which is -04:59.040 --> 00:05:00.880 -and python mode +00:05:21.983 --> 00:05:24.400 +an advantage for some things. -05:00.880 --> 00:05:03.600 -so if i'm in python mode and i run this +00:05:24.500 --> 00:05:27.133 +And this was basically CEDET is, -05:03.600 --> 00:05:06.639 -i get a temporary buffer like this +00:05:27.233 --> 00:05:30.283 +and I use the parse infrastructure -05:06.639 --> 00:05:08.800 -in which this thing is my template for +00:05:30.383 --> 00:05:31.333 +and some tools -05:08.800 --> 00:05:11.120 -the function usually this thing is +00:05:31.433 --> 00:05:34.333 +to create a parser for Common Lisp. -05:11.120 --> 00:05:13.039 -totally wrong i have to rewrite to this +00:05:34.433 --> 00:05:36.700 +Well, more or less. *laughs* -05:13.039 --> 00:05:13.919 -string +00:05:36.800 --> 00:05:37.900 +Let's go to details. -05:13.919 --> 00:05:16.400 -but the rest is right you can see python +00:05:38.000 --> 00:05:39.850 +So I will say that it's not a parser -05:16.400 --> 00:05:18.720 -mode here in the name of the function so +00:05:39.950 --> 00:05:42.433 +by itself because, as we all know, -05:18.720 --> 00:05:21.360 -we have to edit this and save that to +00:05:42.533 --> 00:05:44.500 +to parse a macro-based language -05:21.360 --> 00:05:22.840 -our home +00:05:44.600 --> 00:05:46.833 +is really hard. -05:22.840 --> 00:05:25.520 -slash.mx and by the way these things +00:05:46.933 --> 00:05:48.450 +Mostly if you cannot have contextual -05:25.520 --> 00:05:28.880 -here hyperlinks to many different things +00:05:48.550 --> 00:05:52.800 +information because if you create code -05:28.880 --> 00:05:31.600 -this elias piper link here +00:05:52.900 --> 00:05:56.033 +at compile time or runtime is really hard -05:31.600 --> 00:05:34.160 -points to the source code to the section +00:05:56.133 --> 00:05:59.233 +if you don't have run time, right? -05:34.160 --> 00:05:35.280 -in which +00:05:59.333 --> 00:06:00.950 +Basically, CLEDE can be described -05:35.280 --> 00:05:36.400 -these +00:06:01.050 --> 00:06:02.600 +as a Semantic extension. -05:36.400 --> 00:05:38.400 -functions are defined +00:06:02.700 --> 00:06:03.867 +So basically it's like, -05:38.400 --> 00:05:40.320 -so you can see this here the function +00:06:03.967 --> 00:06:07.133 +you can have Semantic -05:40.320 --> 00:05:41.759 -that supports c +00:06:07.233 --> 00:06:09.817 +and use it with Common Lisp code -05:41.759 --> 00:05:43.440 -the function for haskell the function +00:06:09.917 --> 00:06:11.600 +and some Common Lisp Emacs tools. -05:43.440 --> 00:05:46.400 -for javascript etc +00:06:11.700 --> 00:06:17.350 +So Bison (which is not Bison) is -05:46.400 --> 00:05:49.440 -and that's it this is a five-minute talk +00:06:17.450 --> 00:06:21.650 +Bovine, and Semantic and Senator -05:49.440 --> 00:05:50.960 -so i can't say much +00:06:21.750 --> 00:06:24.750 +for navigating tags, -05:50.960 --> 00:05:52.639 -if you want more information or if you +00:06:24.850 --> 00:06:26.367 +and then communication with SLIME, SLY, -05:52.639 --> 00:05:55.120 -want to see real world examples how i +00:06:26.467 --> 00:06:28.733 +and inferior Lisp. -05:55.120 --> 00:05:58.000 -use test blocks etc etc see this page +00:06:28.833 --> 00:06:30.450 +That means... I will show that later, but -05:58.000 --> 00:06:00.479 -here and i do not have time to explain +00:06:30.550 --> 00:06:32.800 +basically, you can parse the buffer, -06:00.479 --> 00:06:02.560 -this by the way here +00:06:32.900 --> 00:06:34.167 +get some tags, -06:02.560 --> 06:06.080 -so that's it thanks +00:06:34.267 --> 00:06:35.967 +get information about the tags that you want, + +00:06:36.067 --> 00:06:38.017 +and then send some of that information + +00:06:38.117 --> 00:06:43.900 +to the SLIME, SLY, or inferior Lisp REPL buffer, + +00:06:44.000 --> 00:06:45.717 +so you can get both things + +00:06:45.817 --> 00:06:48.483 +at the same time. + +00:06:48.583 --> 00:06:50.217 +And given that it's a Lisp language, + +00:06:50.317 --> 00:06:53.300 +this can be pretty interesting. + +00:06:53.400 --> 00:06:57.600 +Also I wrote some common package integration, + +00:06:57.700 --> 00:06:59.217 +so even though there's not + +00:06:59.317 --> 00:07:00.300 +a Common Lisp standard, + +00:07:00.400 --> 00:07:05.100 +there's some libraries that are used + +00:07:05.200 --> 00:07:07.583 +by basically everyone. + +00:07:07.683 --> 00:07:09.417 +They're not part of the standard, + +00:07:09.517 --> 00:07:11.000 +but yeah. + +00:07:11.100 --> 00:07:13.900 +A lot of people use it: like `asdf`, + +00:07:14.000 --> 00:07:15.550 +which is the package manager, + +00:07:15.650 --> 00:07:18.967 +I will say it's [`asdf` is] the + +00:07:19.067 --> 00:07:21.783 +definition packages, so to say, + +00:07:21.883 --> 00:07:23.667 +better than packages itself + +00:07:23.767 --> 00:07:26.317 +and have more features. + +00:07:26.417 --> 00:07:28.383 +I wrote a nice integration with it + +00:07:28.483 --> 00:07:29.500 +and also `fiveam`, + +00:07:29.600 --> 00:07:34.417 +which is a well-known test package. + +00:07:34.517 --> 00:07:39.300 +I just wrote this as an example + +00:07:39.400 --> 00:07:41.883 +on how we can do with CLEDE. + +00:07:41.983 --> 00:07:43.633 +Let's look at the features, + +00:07:43.733 --> 00:07:46.267 +and then we go to a demo. + +00:07:51.367 --> 00:07:54.000 +You can go to the repository. + +00:07:54.100 --> 00:07:56.550 +Currently, it's not in Melpa + +00:07:56.650 --> 00:07:57.917 +although I wanted + +00:07:58.017 --> 00:08:01.250 +to merge it-- I mean, to add it-- + +00:08:01.450 --> 00:08:04.667 +to Melpa in the future. + +00:08:04.767 --> 00:08:06.367 +I want to clean the code and + +00:08:06.467 --> 00:08:07.417 +add some more features; + +00:08:07.517 --> 00:08:09.650 +I'm working on that and now + +00:08:09.750 --> 00:08:12.567 +like an eagle, so to say... + +00:08:12.667 --> 00:08:15.533 +but yeah, you can go here and then check + +00:08:15.633 --> 00:08:18.833 +all the features and test it. + +00:08:18.933 --> 00:08:20.733 +To install is pretty easy: + +00:08:20.833 --> 00:08:22.500 +just "add to path" thing. + +00:08:22.600 --> 00:08:23.650 +You don't need any external dependencies; + +00:08:23.750 --> 00:08:25.817 +everything's in Emacs. + +00:08:25.917 --> 00:08:28.467 +This was tested with Emacs 27, + +00:08:28.567 --> 00:08:29.883 +but probably going to work + +00:08:29.983 --> 00:08:32.750 +with Emacs 25 onwards so + +00:08:32.850 --> 00:08:34.267 +it shouldn't be any problem. + +00:08:34.367 --> 00:08:38.633 +So let's go with the features. + +00:08:38.733 --> 00:08:42.783 +This is some CEDET integrations, + +00:08:42.883 --> 00:08:44.417 +and first, like I said, it has + +00:08:44.517 --> 00:08:48.000 +support for SLY, SLIME, and inferior Lisp. + +00:08:48.100 --> 00:08:49.517 +If you are Common Lisp developer, you + +00:08:49.617 --> 00:08:52.267 +probably know a SLIME and a SLY, + +00:08:52.367 --> 00:08:53.483 +and inferior Lisp is basically + +00:08:53.583 --> 00:08:57.800 +just stock Emacs REPL. + +00:08:57.900 --> 00:09:00.817 +I support all three equally, so to say, + +00:09:00.917 --> 00:09:05.583 +and we have also `fiveam` integration, + +00:09:05.683 --> 00:09:08.867 +the ability to-- as I'm going to show later, + +00:09:08.967 --> 00:09:10.883 +you have the ability to send a test-- + +00:09:10.983 --> 00:09:16.233 +either packages or an entire suite of tests, + +00:09:16.333 --> 00:09:21.350 +and `asdf`, which currently I'm just + +00:09:21.450 --> 00:09:23.517 +supporting basic project navigation + +00:09:23.617 --> 00:09:25.433 +and some information, + +00:09:25.533 --> 00:09:28.517 +but it's a work-in-progress. + +00:09:28.617 --> 00:09:29.783 +I also have some general activities + +00:09:29.883 --> 00:09:31.917 +that are not directly related to CEDET + +00:09:32.017 --> 00:09:34.050 +but part of the CLEDE package, which + +00:09:34.150 --> 00:09:35.500 +is CLEDE highlight. + +00:09:35.600 --> 00:09:36.817 +It's highly inspired by the + +00:09:36.917 --> 00:09:41.167 +Emacs re-factor `erefactor`. + +00:09:41.267 --> 00:09:43.950 +Basically, you have some nice + +00:09:44.050 --> 00:09:47.883 +highlights for lint variables. + +00:09:47.983 --> 00:09:49.467 +I want to expand that to also + +00:09:49.567 --> 00:09:53.133 +support parameters and function stuff, + +00:09:53.233 --> 00:09:56.300 +but it's not a high priority for me. + +00:09:56.400 --> 00:09:58.117 +But yeah, I sometimes use this; + +00:09:58.217 --> 00:10:01.950 +it's pretty neat when you have a big lint. + +00:10:02.050 --> 00:10:05.333 +Also some refactoring utilities... + +00:10:05.433 --> 00:10:06.700 +some of those can be said + +00:10:06.800 --> 00:10:08.400 +that it's overlapped with some... + +00:10:08.500 --> 00:10:12.467 +because it is a string base, it doesn't + +00:10:12.567 --> 00:10:15.983 +have too much context information, + +00:10:16.083 --> 00:10:17.967 +but yeah, some sort of + +00:10:18.067 --> 00:10:22.167 +`replace-symbol-in-region` and `symbol-tag`. + +00:10:22.267 --> 00:10:23.867 +And then some CLEDE commands. + +00:10:23.967 --> 00:10:25.500 +This is the thing that I use all the time. + +00:10:25.600 --> 00:10:26.067 +It's like you're going to find + +00:10:26.167 --> 00:10:29.067 +some commands to send to a REPL. + +00:10:29.167 --> 00:10:31.367 +I will show some example, but basically, + +00:10:31.467 --> 00:10:32.983 +you have already an example. + +00:10:33.083 --> 00:10:34.333 +You define a list of commands, + +00:10:34.433 --> 00:10:37.867 +you put name, and then you put the + +00:10:37.967 --> 00:10:39.300 +Common Lisp code that you want to send. + +00:10:39.400 --> 00:10:41.550 +Given that, you're writing this + +00:10:41.650 --> 00:10:43.483 +Emacs Lisp in your configuration. + +00:10:43.583 --> 00:10:46.867 +You can have some runtime information + +00:10:46.967 --> 00:10:49.450 +when the code is sent, right? + +00:10:49.550 --> 00:10:53.450 +so insert, get a variable value, or whatever. + +00:10:53.550 --> 00:10:56.133 +OK, `imenu` integration. + +00:10:56.233 --> 00:10:58.967 +Yes, Semantic... + +00:10:59.067 --> 00:11:02.450 +CEDET has a great `imenu` utilities + +00:11:02.550 --> 00:11:05.600 +to have a better `imenu`. + +00:11:05.700 --> 00:11:10.383 +`imenu-list` also works really well. + +00:11:10.483 --> 00:11:12.917 +So you have better... when you go to a file + +00:11:13.017 --> 00:11:15.200 +that you don't fully know what is inside, + +00:11:15.300 --> 00:11:20.533 +it's better to navigate having like a tree. + +00:11:20.633 --> 00:11:22.383 +Yeah, this one's the thing is going + +00:11:22.483 --> 00:11:24.783 +to show that Senator, which is + +00:11:24.883 --> 00:11:26.633 +Semantic navigator, and then some + +00:11:26.733 --> 00:11:30.217 +Semantic-specific tools like `complete-jump`, + +00:11:30.317 --> 00:11:32.750 +which I don't use this one too much + +00:11:32.850 --> 00:11:35.300 +because we have SLY/SLIME, + +00:11:35.400 --> 00:11:39.083 +but they're there, so yeah. + +00:11:39.183 --> 00:11:41.433 +Like I said, Common Lisp library support, + +00:11:41.533 --> 00:11:44.333 +which is duplicated. + +00:11:44.433 --> 00:11:47.017 +OK, so let's go to the demo. + +00:11:47.117 --> 00:11:50.983 +Um. + +00:11:51.083 --> 00:11:53.567 +Let's go to the demo file. + +00:11:53.667 --> 00:11:55.300 +Right. + +00:11:55.400 --> 00:11:58.250 +First, we have to do is enable CLEDE. + +00:11:58.350 --> 00:11:59.433 +This is pretty easy: + +00:11:59.533 --> 00:12:03.400 +we call `clede-start`, right, + +00:12:03.500 --> 00:12:05.100 +and now it's started. + +00:12:05.200 --> 00:12:08.100 +CLEDE is not an asynchronous parser so + +00:12:08.200 --> 00:12:10.900 +Semantic (in this case, Bovine) is not. + +00:12:11.000 --> 00:12:15.917 +If the file is large, it may take some time. + +00:12:16.017 --> 00:12:16.017 +It shouldn't because we have + +00:12:16.117 --> 00:12:19.117 +powerful computers, but if your + +00:12:19.217 --> 00:12:21.917 +computer is not that powerful, + +00:12:22.017 --> 00:12:22.933 +it may take a while. + +00:12:23.033 --> 00:12:26.117 +To see the information that has been + +00:12:26.217 --> 00:12:31.167 +parsed, we're going to call `bovinate`. + +00:12:31.267 --> 00:12:33.767 +Oops... oops... + +00:12:33.867 --> 00:12:36.033 +Oh! I have to-- sorry... + +00:12:36.133 --> 00:12:43.267 +Let's enable Semantic again. + +00:12:43.367 --> 00:12:45.217 +Let's start... `bovinate`... + +00:12:45.317 --> 00:12:48.117 +OK, so... + +00:12:48.217 --> 00:12:49.917 +This is the information that + +00:12:50.017 --> 00:12:52.983 +currently CLEDE is taking from the buffer. + +00:12:53.083 --> 00:12:55.517 +So we can see it's taking this, and + +00:12:55.617 --> 00:12:58.550 +it doesn't know what it is, + +00:12:58.550 --> 00:13:02.167 +so this is the tag name... + +00:13:02.267 --> 00:13:02.850 +this is the type, + +00:13:02.950 --> 00:13:03.733 +and these are some information + +00:13:03.833 --> 00:13:05.750 +and the location. + +00:13:05.850 --> 00:13:08.150 +OK, so we know that this is a variable, + +00:13:08.250 --> 00:13:10.150 +and it has the full value. + +00:13:10.250 --> 00:13:13.233 +You know this is a package, right, + +00:13:13.333 --> 00:13:15.450 +because it's defined as a package. + +00:13:15.550 --> 00:13:18.100 +It doesn't understand what this is. + +00:13:18.300 --> 00:13:18.967 +This node is a function + +00:13:19.067 --> 00:13:19.817 +because of the `fun`, + +00:13:19.917 --> 00:13:23.133 +and some of this is code, + +00:13:23.233 --> 00:13:25.917 +and it also understands some tests + +00:13:26.017 --> 00:13:27.667 +because it has `fiveam` integration. + +00:13:27.767 --> 00:13:31.000 +If it detects that has some test here + +00:13:31.000 --> 00:13:34.517 +it will know that, indeed, it is test. + +00:13:34.517 --> 00:13:40.317 +So let's try some, first, `imenu`. + +00:13:40.417 --> 00:13:42.550 +So we can see here we have... + +00:13:42.650 --> 00:13:44.750 +I understand that this have + +00:13:44.850 --> 00:13:46.600 +some sort of `fiveam` switch + +00:13:46.700 --> 00:13:49.350 +and some tests defined. + +00:13:49.450 --> 00:13:51.000 +It understands this package, and + +00:13:51.100 --> 00:13:52.783 +it'll give you some variables-- `defuns`, + +00:13:52.883 --> 00:13:55.117 +and it also will give you some misc + +00:13:55.217 --> 00:13:59.917 +for things that doesn't know what it is. + +00:14:00.017 --> 00:14:00.983 +And you can also + +00:14:01.083 --> 00:14:04.417 +navigate with this-- like this `imenu`. + +00:14:06.000 --> 00:14:12.000 +So, um, let's go first with some Senator. + +00:14:12.000 --> 00:14:14.867 +So with Senator, we can navigate, + +00:14:14.967 --> 00:14:16.200 +go to the next stack, previous stack, + +00:14:16.300 --> 00:14:20.783 +all this, um, top-level `s-expression` + +00:14:20.883 --> 00:14:22.467 +are basically a tag, even though + +00:14:22.567 --> 00:14:28.467 +it's code... you can navigate, right. + +00:14:28.567 --> 00:14:31.333 +Um, copy/kill this or some other stuff. + +00:14:31.433 --> 00:14:34.017 +Um, some interesting thing that we can + +00:14:34.117 --> 00:14:38.717 +do is let's launch SLY, right. + +00:14:38.817 --> 00:14:44.317 +Um, let's load `fiveam`, + +00:14:44.417 --> 00:14:45.500 +and let's send some tests. + +00:14:45.600 --> 00:14:51.467 +We can say, OK, `clede-fiveam-send-current-test`, + +00:14:51.567 --> 00:14:53.033 +and it will-- OK, have to compile + +00:14:53.133 --> 00:14:54.750 +this file first. + +00:14:54.850 --> 00:14:55.983 +OK, you don't like this... + +00:14:56.083 --> 00:14:58.367 +you compile the tests. + +00:14:58.467 --> 00:15:03.667 +OK... um... well... + +00:15:03.767 --> 00:15:05.017 +I don't have-- yeah, I don't have + +00:15:05.117 --> 00:15:11.833 +the switch here so let's... + +00:15:11.933 --> 00:15:14.733 +OK, yeah because I guess it's getting... + +00:15:14.833 --> 00:15:19.583 +sorry about this... + +00:15:19.683 --> 00:15:22.983 +Let's say we're going to send this test... + +00:15:23.083 --> 00:15:28.667 +It isn't working... + +00:15:28.767 --> 00:15:36.967 +OK, why are you not working... + +00:15:37.067 --> 00:15:38.450 +maybe because we have to go + +00:15:38.550 --> 00:15:47.083 +to the package `fiveam`. + +00:15:47.183 --> 00:15:49.133 +Yes, sorry... um... + +00:15:49.233 --> 00:15:51.550 +Yeah, so we're gonna go here, and + +00:15:51.650 --> 00:15:54.117 +we can say `fiveam-send-tests`, + +00:15:54.217 --> 00:15:55.250 +and there we have it. + +00:15:55.350 --> 00:15:56.200 +It will send the test + +00:15:56.300 --> 00:16:00.217 +that we are currently in, right. + +00:16:00.317 --> 00:16:01.883 +So that's the thing. + +00:16:01.983 --> 00:16:04.000 +Another interesting thing that I said is + +00:16:04.000 --> 00:16:08.450 +`clede-highlight-minor-mode`. + +00:16:08.550 --> 00:16:11.567 +Basically, work in `let`'s context + +00:16:11.667 --> 00:16:13.450 +to know where to highlight + +00:16:13.550 --> 00:16:17.117 +all the variables, + +00:16:17.217 --> 00:16:20.217 +and we can disable. + +00:16:20.317 --> 00:16:21.833 +What else do we have? + +00:16:21.933 --> 00:16:24.100 +So we have framework integration. + +00:16:24.200 --> 00:16:25.900 +You can go `clede-` and + +00:16:26.000 --> 00:16:27.717 +see what more commands are. + +00:16:27.817 --> 00:16:29.767 +`commands-run` are basically a way + +00:16:29.867 --> 00:16:31.617 +to define commands, you have a variable, + +00:16:31.717 --> 00:16:35.317 +which is `clede-commands-list`. + +00:16:35.417 --> 00:16:37.233 +Let's explain that you can get + +00:16:37.333 --> 00:16:39.817 +some system working + +00:16:39.917 --> 00:16:42.617 +or whatever command you want, right. + +00:16:42.717 --> 00:16:46.083 +Also you have `asdf` basic integration. + +00:16:46.183 --> 00:16:48.067 +You can go to a definition file + +00:16:48.167 --> 00:16:51.050 +of some of the systems are already loaded. + +00:16:51.150 --> 00:16:53.667 +For example, let's go to here, + +00:16:53.767 --> 00:16:55.550 +and we go to the definition file-- + +00:16:55.650 --> 00:16:57.917 +there's the file, right? + +00:16:58.017 --> 00:16:59.000 +This is used because I'm sending + +00:16:59.100 --> 00:17:00.800 +commands for the REPL, so this + +00:17:00.900 --> 00:17:04.117 +functionality is not provided + +00:17:04.217 --> 00:17:09.167 +by CEDET or Semantic, + +00:17:09.267 --> 00:17:11.633 +but I can also get some sort + +00:17:11.733 --> 00:17:19.717 +of information for `asd` file, + +00:17:19.817 --> 00:17:21.550 +which is a work-in-progress, + +00:17:21.650 --> 00:17:23.100 +but you can go to some component file + +00:17:23.200 --> 00:17:24.150 +when you have a big `asd` file + +00:17:24.250 --> 00:17:25.200 +with lots of components + +00:17:25.300 --> 00:17:27.783 +and some other interesting thing. + +00:17:27.883 --> 00:17:30.283 +Like I said, that's a work-in-progress, + +00:17:30.383 --> 00:17:34.967 +Yes, so this is most of the functionality. + +00:17:35.067 --> 00:17:37.000 +The most interesting thing, I think, + +00:17:37.100 --> 00:17:40.267 +is the base for the foundation. + +00:17:40.367 --> 00:17:43.000 +So you can expand: let's go to source code, + +00:17:43.100 --> 00:17:48.333 +for example, that `fiveam`. + +00:17:48.433 --> 00:17:49.900 +So as we can see here, this is + +00:17:50.000 --> 00:17:53.433 +the `fiveam` integration, and to add it, + +00:17:53.533 --> 00:17:58.233 +I just define some new functions, + +00:17:58.333 --> 00:18:01.983 +and then you use this... + +00:18:02.083 --> 00:18:04.150 +set up a new form parser that we use + +00:18:04.250 --> 00:18:06.400 +to get some information + +00:18:06.500 --> 00:18:09.150 +about the `s-expression` top-level, + +00:18:09.250 --> 00:18:10.433 +and we define the names, + +00:18:10.533 --> 00:18:11.617 +we define information we want to take + +00:18:11.717 --> 00:18:13.700 +from the symbol and everything else. + +00:18:13.800 --> 00:18:17.133 +Also some [??] types + +00:18:17.233 --> 00:18:19.367 +that would be going to be added + +00:18:19.467 --> 00:18:21.067 +to the `imenu` thing: + +00:18:21.167 --> 00:18:24.033 +for example, `imenu test switch and test`. + +00:18:24.133 --> 00:18:27.317 +And then, these are, for example, + +00:18:27.417 --> 00:18:29.333 +some function to send information + +00:18:29.433 --> 00:18:33.483 +to the SLY, SLIME, or inferior Lisp + +00:18:33.583 --> 00:18:37.050 +depending on the Lisp that you're using. + +00:18:37.150 --> 00:18:39.400 +So I do not have more time. + +00:18:39.500 --> 00:18:40.367 +Sorry about that. + +00:18:40.467 --> 00:18:44.917 +Thank you very much. + +00:18:45.017 --> 00:18:46.383 +My name is Fermin. + +00:18:46.483 --> 00:18:49.733 +You can send me a mail in my mail, + +00:18:49.833 -->

+ +02:13.308 --> 02:20.128 +Unfortunately, not really as few as we would like. + +02:20.234 --> 02:25.294 +In GNU Emacs, we have about 1500 primitives, + +02:25.400 --> 02:27.970 +and the main reason for that is performance. + +02:28.071 --> 02:30.961 +Actually, GNU Emacs was written + +02:31.064 --> 02:34.292 +when performance was a big issue, + +02:34.393 --> 02:36.493 +and nowadays certain parts + +02:36.594 --> 02:38.486 +are still performance-critical. + +02:38.591 --> 02:40.295 +We have a lot of C code; + +02:40.395 --> 02:46.331 +30% of the GNU Emacs codebase is C code, + +02:46.435 --> 02:49.177 +and we have to maintain this. + +02:49.279 --> 02:52.859 +But not only that, this is the main barrier + +02:52.959 --> 02:55.579 +for people that tried in the past + +02:55.681 --> 02:57.663 +to change the Emacs Lisp implementation. + +02:57.765 --> 02:59.101 +Because not only do you have to + +02:59.202 --> 03:01.582 +replace these primitives, + +03:01.683 --> 03:03.907 +all of them or part of them, + +03:04.012 --> 03:06.384 +but sometimes they also share (these primitives), + +03:06.484 --> 03:07.952 +internal data structures. + +03:08.055 --> 03:09.745 +For instance, it's very difficult to say: + +03:09.846 --> 03:12.826 +Now I want to go from C + +03:12.926 --> 03:13.906 +to a different programming language + +03:14.006 --> 03:15.638 +for implementing these primitives. + +03:15.740 --> 03:17.028 +So this has been, effectively, + +03:17.128 --> 03:20.380 +the main barrier for doing this work. + +03:20.486 --> 03:22.090 +Another interesting aspect + +03:22.190 --> 03:23.870 +about the GNU Emacs implementation + +03:23.970 --> 03:26.190 +is that Lisp can run interpreted + +03:26.291 --> 03:28.647 +or byte-compiled for performance, + +03:28.752 --> 03:30.632 +and the byte compiler itself + +03:30.733 --> 03:32.673 +is written in Emacs Lisp. + +03:32.773 --> 03:35.033 +This implies that GNU Emacs has to go through + +03:35.134 --> 03:37.214 +a bootstrap procedure in order to be built. + +03:37.319 --> 03:38.715 +But it's kind of interesting + +03:38.815 --> 03:41.835 +for something that started as a text editor, + +03:41.937 --> 03:43.101 +or something like it. + +03:43.203 --> 03:47.877 +The byte-code that is Emacs Lisp + +03:47.979 --> 03:50.279 +when it's been byte compiled, + +03:50.379 --> 03:53.079 +it's running on a stack-based virtual machine + +03:53.180 --> 03:55.146 +that is implemented in C. + +03:55.253 --> 03:59.741 +OK, so I've listed a bunch of areas + +03:59.842 --> 04:02.074 +where Emacs Lisp could improve: + +04:02.178 --> 04:06.924 +Namespace, Extensibility, Performance, + +04:07.025 --> 04:11.239 +and Debuggability, and Diagnostic, we could say. + +04:11.346 --> 04:14.326 +This activity, this project in particular, + +04:14.428 --> 04:17.088 +is affecting primarily Performance + +04:17.189 --> 04:21.314 +and the performance area the Execution Engine. + +04:21.414 --> 04:22.570 +That said, + +04:22.671 --> 04:25.855 +I think it has an impact also on Extensibility, + +04:25.957 --> 04:27.811 +and I hope it will have an impact also + +04:27.913 --> 04:29.779 +on programming diagnostics, + +04:29.881 --> 04:32.501 +so giving better warnings, [unknown]. + +04:32.604 --> 04:36.694 +So which are the benefits + +04:36.795 --> 04:39.215 +of increasing the Emacs Lisp performance? + +04:39.316 --> 04:42.976 +Indeed, we will have, if we do that, + +04:43.078 --> 04:45.668 +programs that run faster. + +04:45.774 --> 04:48.738 +But the main implication of that + +04:48.840 --> 04:50.760 +is that we could write less C; + +04:50.860 --> 04:52.940 +we could maintain and debug less C. + +04:53.041 --> 04:56.437 +That is kind of a time-consuming task. + +04:56.542 --> 04:59.502 +And we could also allow for + +04:59.603 --> 05:01.723 +writing performance-critical extensions + +05:01.824 --> 05:03.804 +directly in Lisp + +05:03.909 --> 05:06.305 +without having to use systems like + +05:06.406 --> 05:09.686 +[I think there's a bunch.] + +05:09.927 --> 05:14.791 +These are very consistent benefits. + +05:14.899 --> 05:16.669 +OK, Project Goals, + +05:16.769 --> 05:18.829 +but I think the title of this slide + +05:18.930 --> 05:21.520 +maybe should be Project Requirements. + +05:21.623 --> 05:23.231 +So when I started this activity, + +05:23.331 --> 05:26.943 +I set some requirements for the project, + +05:27.049 --> 05:29.469 +with the main goal in mind: to go upstream. + +05:29.570 --> 05:31.494 +So I wanted to create something, + +05:31.594 --> 05:34.250 +a modified implementation of GNU Emacs, + +05:34.353 --> 05:36.675 +that was compatible + +05:36.776 --> 05:38.596 +as close to 100% as possible + +05:38.696 --> 05:40.514 +to the current implementation. + +05:40.620 --> 05:42.720 +And when I say "current implementation," + +05:42.820 --> 05:44.758 +I don't refer to what + +05:44.859 --> 05:46.879 +the Emacs Lisp Programming Manual specifies + +05:46.980 --> 05:49.804 +as expected behavior of the implementation, + +05:49.907 --> 05:52.207 +but really the implementation itself. + +05:52.309 --> 05:53.841 +This is because there are a lot of corner cases + +05:53.942 --> 05:56.390 +that are not specified by the manual, + +05:56.493 --> 05:58.093 +but programs do rely on that, + +05:58.193 --> 06:00.523 +and given there is a ton of Emacs Lisp + +06:00.625 --> 06:01.935 +already around, + +06:02.037 --> 06:05.437 +compatibility was definitely a major requirement. + +06:05.541 --> 06:07.727 +I wanted to produce something that had + +06:07.827 --> 06:09.587 +reduced impact on the Emacs codebase, + +06:09.687 --> 06:11.543 +at least as much as possible. + +06:11.644 --> 06:14.724 +So I didn't want to rewrite all of GNU Emacs. + +06:14.827 --> 06:17.609 +Indeed, because it would have been + +06:17.710 --> 06:21.068 +too much work for one single person, + +06:21.171 --> 06:25.371 +but also still thinking + +06:25.473 --> 06:29.153 +to an upstream outcome all of this time. + +06:29.258 --> 06:31.974 +Another requirement was to have + +06:32.076 --> 06:34.700 +no, or very reduced, impact on the user, + +06:34.804 --> 06:36.456 +so I didn't want to change + +06:36.556 --> 06:38.604 +the way Emacs is used by you. + +06:38.708 --> 06:40.618 +And last but not least, + +06:40.718 --> 06:42.848 +introducing new dependencies, + +06:42.951 --> 06:45.379 +those dependencies had to be Free Software, + +06:45.479 --> 06:47.191 +possibly GPL, + +06:47.295 --> 06:49.995 +and also an important requirement + +06:50.097 --> 06:52.941 +is that these dependencies had to be + +06:53.043 --> 06:55.143 +some kind of trusted software that we know + +06:55.243 --> 06:56.681 +is going to be maintained in the future. + +06:56.781 --> 06:59.261 +Given Emacs has been around since forever, + +06:59.363 --> 07:01.183 +and will be around forever and ever, + +07:01.285 --> 07:05.265 +this was another very important point. + +07:05.367 --> 07:08.707 +A little bit of history of this project/ + +07:08.808 --> 07:10.648 +a quick timeline. + +07:10.748 --> 07:14.388 +2019, in May, I did my first commit, + +07:14.490 --> 07:17.110 +I think it was when I tried to write + +07:17.210 --> 07:20.230 +my first primitive function ever in C, + +07:20.332 --> 07:21.752 +in GNU Emacs. + +07:21.852 --> 07:24.832 +And this was an attempt to try to compile + +07:24.934 --> 07:30.314 +a function that, once executed, returning [?] + +07:30.415 --> 07:33.755 +That was it. Six months after (about), + +07:33.857 --> 07:37.057 +I had something that was kind of working, + +07:37.157 --> 07:42.797 +So I was able to start up a semi-standard Emacs + +07:42.899 --> 07:44.879 +and then to compile and load, + +07:44.981 --> 07:47.221 +and replacing most of the functions + +07:47.321 --> 07:50.921 +that I had defined floating in my Lisp universe. + +07:51.022 --> 07:54.202 +Those functions are the functions + +07:54.304 --> 07:55.944 +that are essentially composing Emacs, + +07:56.044 --> 07:57.884 +at least the Lisp side of Emacs. + +07:57.984 --> 08:01.084 +A lot of features were missing, + +08:01.186 --> 08:03.426 +like I had no Garbage Collector support, + +08:03.526 --> 08:07.006 +no bootstrap, I was not optimizing these functions + +08:07.108 --> 08:10.068 +Because optimization [would be broken]. + +08:10.169 --> 08:12.749 +No image dump support, etc. + +08:12.850 --> 08:16.330 +But I think this proved the design could work. + +08:16.431 --> 08:19.171 +So I sent to email to emacs-devel. I said + +08:19.272 --> 08:20.852 +I have this stuff I'm working on, + +08:20.953 --> 08:24.613 +and I wanted some feedback from the upstream + +08:24.714 --> 08:27.534 +to see if there was some interest. + +08:27.635 --> 08:30.455 +I believe the outcome of this was positive + +08:30.557 --> 08:32.837 +because about one month after, + +08:32.937 --> 08:35.697 +I pushed my branch within the Emacs git + +08:35.798 --> 08:38.438 +as a feature branch, and shortly after, + +08:38.539 --> 08:42.679 +we started to use the bug tracker to track bugs. + +08:42.779 --> 08:45.479 +So essentially we moved the development + +08:45.580 --> 08:50.040 +on the upstream infrastructure. + +08:50.140 --> 08:55.620 +I believe two years after the first commit, + +08:55.721 --> 08:57.781 +the project was merged + +08:57.882 --> 09:00.922 +after literally hundreds of bugs solved, + +09:01.022 --> 09:03.842 +and improvements, suggestions [unknown] + +09:03.943 --> 09:08.623 +and this was about six months ago. + +09:08.723 --> 09:12.363 +Before discussing how the native compiler works, + +09:12.464 --> 09:14.224 +I think it's worth looking at + +09:14.324 --> 09:17.644 +how Lisp is implemented in GNU Emacs. + +09:17.745 --> 09:19.305 +We have Lisp_Objects + +09:19.405 --> 09:21.945 +floating around our Lisp universe, + +09:22.045 --> 09:23.905 +and they are internally represented in this way. + +09:24.006 --> 09:25.606 +We have what is called a tagged pointer, + +09:25.706 --> 09:27.406 +that is just a regular pointer + +09:27.506 --> 09:29.286 +that is pointing to the area of memory + +09:29.386 --> 09:31.926 +where we hold the real data of the object. + +09:32.027 --> 09:34.187 +But within this tagged pointer, + +09:34.287 --> 09:36.747 +we reserve a few bits + +09:36.848 --> 09:38.968 +to indicate the type of object we are pointing to. + +09:39.068 --> 09:40.528 +This is important because + +09:40.628 --> 09:42.288 +each time we access an object, + +09:42.388 --> 09:46.168 +we have to typically check those bits + +09:46.269 --> 09:49.029 +to check that the object we are manipulating + +09:49.129 --> 09:50.529 +is of the right kind, + +09:50.630 --> 09:52.530 +remove those bits, and, if we are happy, + +09:52.630 --> 09:55.810 +access the object, otherwise [unknown]. + +09:55.910 --> 09:57.690 +All the objects are like this, + +09:57.791 --> 09:59.731 +except for typically Fixnums, + +09:59.831 --> 10:01.031 +that are small integers + +10:01.131 --> 10:04.891 +that we manage to fit directly within the pointer. + +10:04.992 --> 10:07.292 +Also for manipulating Fixnums, + +10:07.392 --> 10:09.412 +we have to check the tag bits each time. + +10:09.513 --> 10:13.173 +Whenever we are not sure of the type of object + +10:13.273 --> 10:16.493 +we are manipulating (read: almost every time), + +10:16.594 --> 10:18.914 +we have to check those bits and remove those bits + +10:19.014 --> 10:21.754 +before doing any manipulation on the Fixnum. + +10:21.854 --> 10:26.014 +How Emacs Lisp is byte-compiled and executed + +10:26.115 --> 10:27.775 +in, let's call it, "Vanilla". + +10:27.875 --> 10:30.055 +If we have a Lisp expression of this kind: + +10:30.156 --> 10:32.776 +We take the variable 'a' we do plus 2, + +10:32.876 --> 10:34.876 +and then we multiply the result by 3, + +10:34.976 --> 10:37.376 +the byte compiler will produce this LAP code. + +10:37.477 --> 10:38.497 +LAP code is essentially + +10:38.597 --> 10:40.017 +the assembly for the byte-code, + +10:40.117 --> 10:43.697 +so it's the "intermediate representation" + +10:43.798 --> 10:48.458 +that will assembled into byte-code. (.elc files) + +10:48.558 --> 10:50.738 +How is this program executed? + +10:50.839 --> 10:53.639 +As I mentioned, it's executed in a virtual machine + +10:53.739 --> 10:55.699 +that is stack-based, + +10:55.800 --> 10:58.540 +but we start with an execution stack that's empty, + +10:58.640 --> 11:01.680 +and a stack pointer pointing to its bottom. + +11:01.780 --> 11:04.280 +And we execute the first instruction, + +11:04.380 --> 11:07.120 +that is pushing in the stack the value of 'a', + +11:07.220 --> 11:10.360 +in this case, 100. Then we push the constant 2. + +11:10.460 --> 11:12.400 +Then we do the summation, + +11:12.500 --> 11:14.040 +and we have the result in the stack. + +11:14.140 --> 11:16.860 +Same: we push the constant 3, + +11:16.960 --> 11:17.620 +we do the multiplication, + +11:17.720 --> 11:19.260 +and we will be able to return. + +11:19.360 --> 11:22.700 +Now, what's good and what's bad about this? + +11:22.800 --> 11:25.800 +A good thing is that it's very simple + +11:25.900 --> 11:27.460 +to start from Lisp + +11:27.560 --> 11:31.320 +and compile this kind of LAP output. + +11:31.420 --> 11:34.240 +At least it's reasonably simple. + +11:34.340 --> 11:36.240 +The compiler is not that complex. + +11:36.340 --> 11:39.000 +The bad thing is that all this machinery + +11:39.100 --> 11:40.660 +-- push and pop, etc. -- + +11:40.760 --> 11:44.320 +it's very different from how a modern CPU works. + +11:44.420 --> 11:45.720 +Because modern CPUs, + +11:45.820 --> 11:47.660 +they are not stack-based anymore + +11:47.760 --> 11:50.900 +but they have instead a fixed number of registers, + +11:51.000 --> 11:54.020 +and they work with assignment and operation + +11:54.120 --> 11:55.040 +within these registers + +11:55.140 --> 11:57.040 +that are generally called "general-purpose." + +11:57.140 --> 11:59.260 +So to execute this LAP program, + +11:59.360 --> 12:00.760 +there is another program, + +12:00.860 --> 12:02.600 +that is the implementation of the VM itself + +12:02.700 --> 12:06.400 +that is doing conversion during runtime. + +12:06.500 --> 12:08.320 +So it's interpreting the LAP program + +12:08.420 --> 12:11.360 +and it's converting it into instructions + +12:11.460 --> 12:13.180 +that we can execute on the CPU. + +12:13.280 --> 12:14.940 +This conversion is done each time + +12:15.040 --> 12:17.100 +we will run some byte-code. + +12:17.200 --> 12:19.760 +And it's something that we want to avoid. + +12:19.860 --> 12:21.560 +Instead of this live conversion, + +12:21.660 --> 12:26.220 +we want to convert once: + +12:26.320 --> 12:28.920 +our Lisp program into native code, + +12:29.020 --> 12:32.380 +that is, a binary program that can be executed + +12:32.480 --> 12:34.400 +directly by our CPU. + +12:34.500 --> 12:36.680 +We want to save all this unnecessary conversion + +12:36.780 --> 12:39.000 +that we do each time we are running a program + +12:39.100 --> 12:39.760 +while we are running it. + +12:39.860 --> 12:42.060 +And we want to do this process just once, + +12:42.160 --> 12:43.740 +when we are compiling. + +12:43.840 --> 12:46.240 +That's the main goal of this activity. + +12:46.340 --> 12:50.200 +How is the byte compiler implemented? + +12:50.300 --> 12:53.940 +As any compiler it's a pipeline of transformations. + +12:54.040 --> 12:58.560 +We go through macro expansion, closure conversion, + +12:58.660 --> 13:02.120 +we have a bunch of source level optimization. + +13:02.220 --> 13:03.940 +Then we go into LAP, + +13:04.040 --> 13:06.800 +that's the transformation we are interested in, + +13:06.900 --> 13:10.600 +and after a few optimizations on LAP, + +13:10.700 --> 13:14.140 +LAP is assembled into byte-code. + +13:14.240 --> 13:16.880 +So if we [list it] + +13:16.980 --> 13:19.320 +in terms of intermediate representations, + +13:19.420 --> 13:23.600 +we can simplify this pipeline like this. + +13:23.700 --> 13:26.100 +We start with Lisp, and at a certain point + +13:26.200 --> 13:29.520 +we are manipulating the program in LAP form, + +13:29.620 --> 13:31.980 +and then at the end we produce the byte-code + +13:32.080 --> 13:34.560 +that is the .elc file that [you run] + +13:34.660 --> 13:37.660 +What I wanted to realize was something like this. + +13:37.760 --> 13:41.200 +I wanted to start from LAP, do something, + +13:41.300 --> 13:44.600 +and jump into GCC using libgccjit + +13:44.700 --> 13:45.560 +and in particular + +13:45.660 --> 13:48.000 +the libgccjit Intermediate Representation + +13:48.100 --> 13:50.340 +that we will discuss. + +13:50.440 --> 13:53.120 +Now, why I wanted to do something like this? + +13:53.220 --> 13:57.300 +Essentially, writing a compiler from scratch + +13:57.400 --> 14:01.520 +for Emacs Lisp would have been a very big task. + +14:01.620 --> 14:05.120 +So I wanted to rely on, as much as I could, + +14:05.220 --> 14:07.180 +the Emacs Lisp byte compiler, + +14:07.280 --> 14:10.280 +because I had to produce something + +14:10.380 --> 14:12.920 +that was as compatible as possible + +14:13.020 --> 14:14.240 +to the current implementation. + +14:14.340 --> 14:18.340 +So this was (I believe) a very good idea + +14:18.440 --> 14:20.520 +to save an enormous quantity of work + +14:20.620 --> 14:22.340 +and to produce something + +14:22.440 --> 14:24.940 +that was compatible in terms of semantics + +14:25.040 --> 14:26.820 +with the original implementation. + +14:26.920 --> 14:30.660 +Also, I didn't want to implement a code generator + +14:30.760 --> 14:32.860 +for each architecture we were targeting, + +14:32.960 --> 14:35.900 +nor wanted to implement all these optimizations + +14:36.000 --> 14:37.840 +that are already in GCC, + +14:37.940 --> 14:40.120 +so I thought it was a good idea + +14:40.220 --> 14:44.720 +to rely on an existing compiler like GCC [?]. + +14:44.820 --> 14:47.240 +Let's talk about libgccjit. + +14:47.340 --> 14:50.180 +It was added by David Malcolm in GCC 5 + +14:50.280 --> 14:55.680 +It allows you to describe a C-ish semantic to GCC + +14:55.780 --> 14:57.380 +and have it compile. + +14:57.480 --> 15:01.400 +It's good for [reading] Jitters or AoT compilers. + +15:01.500 --> 15:04.400 +And if we talk about GCC: + +15:04.500 --> 15:07.180 +it's a compiler, it's a very good one, + +15:07.280 --> 15:09.340 +it has support for a remarkable number + +15:09.440 --> 15:11.640 +of target architectures. + +15:11.740 --> 15:15.080 +It's also very good at generating [fast code], + +15:15.180 --> 15:17.980 +and it's been around for a long time; + +15:18.080 --> 15:21.200 +I believe it's like 1 year younger than Emacs. + +15:21.300 --> 15:23.220 +It's still very well maintained, + +15:23.320 --> 15:25.840 +and we can assume it will be maintained + +15:25.940 --> 15:28.920 +for quite a while. And, as I mentioned, + +15:29.020 --> 15:31.120 +this was a very important point. + +15:31.220 --> 15:33.860 +Also, it's GPL; it's Free Software, + +15:33.960 --> 15:36.120 +and it's developed under the GNU umbrella, + +15:36.220 --> 15:40.360 +so I thought it was a very good option. + +15:40.460 --> 15:43.300 +So we can imagine a simple translation + +15:43.400 --> 15:46.400 +that goes from LAP to this subset of C + +15:46.500 --> 15:48.880 +that we can describe to libgccjit. + +15:48.980 --> 15:52.880 +This simple translation we can see here, + +15:52.980 --> 15:55.680 +it's actually pretty trivial. + +15:55.780 --> 15:58.500 +Instead of doing operations + +15:58.600 --> 16:02.060 +within the execution stack we have seen before, + +16:02.160 --> 16:05.080 +we have just an array that is replacing it, + +16:05.180 --> 16:07.380 +and it's called 'local' in this case, + +16:07.480 --> 16:12.360 +and we have assignments within this array, + +16:12.460 --> 16:15.140 +so that they are done in place of the original + +16:15.240 --> 16:17.100 +push and pop activity of the stack. + +16:17.200 --> 16:18.280 +The nice thing is that, + +16:18.380 --> 16:20.260 +when you have done this translation, + +16:20.360 --> 16:23.160 +GCC will be able to optimize this, + +16:23.260 --> 16:25.840 +and remove all the unnecessary operations, + +16:25.940 --> 16:27.180 +and generate code + +16:27.280 --> 16:29.660 +for the specific CPU you are targeting, + +16:29.760 --> 16:32.020 +[which will be running your code]. + +16:32.120 --> 16:34.920 +This sounds great; it sounds like + +16:35.020 --> 16:37.440 +a very simple and effective translation, + +16:37.540 --> 16:39.920 +and in fact the first iteration of my compiler + +16:40.020 --> 16:41.120 +was doing just this. + +16:41.220 --> 16:45.320 +It was essentially a big C function + +16:45.420 --> 16:48.240 +that was taking LAP and doing this conversion + +16:48.340 --> 16:50.120 +describing the output to libgccjit. + +16:50.220 --> 16:53.720 +Unfortunately, if you do this, + +16:53.820 --> 16:55.740 +you will discover that you have + +16:55.840 --> 17:00.080 +a performance upper bound limit of about 3x. + +17:00.180 --> 17:04.360 +So it was an option, + +17:04.460 --> 17:06.560 +but I thought it was a good occasion + +17:06.660 --> 17:08.980 +for trying to do something more. + +17:09.080 --> 17:11.640 +And doing something more means + +17:11.740 --> 17:13.680 +implementing a smarter compiler + +17:13.780 --> 17:17.180 +that is doing some advanced analysis on the code, + +17:17.280 --> 17:18.640 +and will be able to perform + +17:18.740 --> 17:20.700 +Lisp-specific optimizations + +17:20.800 --> 17:22.480 +-- optimizations that take advantage of + +17:22.580 --> 17:24.960 +the specific Lisp semantics, + +17:25.060 --> 17:27.760 +something that GCC is not aware of. + +17:27.860 --> 17:31.240 +And while I was thinking about that, + +17:31.340 --> 17:34.000 +I thought that having a smarter compiler + +17:34.100 --> 17:38.120 +had also other advantages, like a smarter compiler + +17:38.220 --> 17:40.120 +that understands the semantics + +17:40.220 --> 17:41.820 +of the programming language being compiled + +17:41.920 --> 17:43.680 +would be also capable of + +17:43.780 --> 17:45.620 +giving feedback to the programmers, + +17:45.720 --> 17:47.920 +like better warnings and errors. + +17:48.020 --> 17:51.360 +So I was really fascinated about this idea, + +17:51.460 --> 17:53.240 +and I wanted to change my implementation + +17:53.340 --> 17:55.920 +because I was not really happy about it. + +17:56.020 --> 17:58.320 +I had a lot of C code in terms of + +17:58.420 --> 18:02.100 +lines that were not doing any smart job. + +18:02.200 --> 18:07.380 +And I wanted to write all the interesting logic + +18:07.480 --> 18:09.940 +[in Lisp]. + +18:10.040 --> 18:12.560 +So optimizing outside GCC + +18:12.660 --> 18:15.840 +before jumping into GCC, + +18:15.940 --> 18:20.500 +as I mentioned, has two main targets: + +18:20.600 --> 18:23.060 +Either optimize the code before going into GCC, + +18:23.160 --> 18:25.380 +or present to GCC some code + +18:25.480 --> 18:27.740 +that we know GCC can optimize effectively. + +18:27.840 --> 18:30.800 +And also, this will give, as I mentioned, + +18:30.900 --> 18:32.660 +better options for the compiler + +18:32.760 --> 18:34.420 +to provide warnings, errors + +18:34.520 --> 18:36.340 +-- better diagnostics. + +18:36.440 --> 18:38.200 +So this is pretty much + +18:38.300 --> 18:40.640 +what the native compiler looks like nowadays, + +18:40.740 --> 18:42.720 +in terms of passes. + +18:42.820 --> 18:44.560 +We have a list of passes, + +18:44.660 --> 18:46.620 +each of which is taking an input + +18:46.720 --> 18:48.120 +and producing an output. + +18:48.220 --> 18:51.040 +So it's doing either analysis on the program + +18:51.140 --> 18:52.640 +that's being passed, + +18:52.740 --> 18:54.760 +or it's performing a transformation. + +18:54.860 --> 18:57.900 +All of these passes are implemented in Lisp, + +18:58.000 --> 19:00.440 +and only the last pass is implemented in C. + +19:00.540 --> 19:05.060 +That is the one that is talking to libgccjit. + +19:05.160 --> 19:07.760 +To do that, I have introduced + +19:07.860 --> 19:10.640 +a new intermediate representation + +19:10.740 --> 19:13.960 +that I call LIMPLE, as a tribute to GCC GIMPLE, + +19:14.060 --> 19:17.220 +that is the main internal representation of GCC, + +19:17.320 --> 19:20.600 +at least one of the main ones. + +19:20.700 --> 19:25.080 +Introducing a new intermediate representation + +19:25.180 --> 19:27.720 +-- a new way of representing my program -- + +19:27.820 --> 19:29.540 +solved a bunch of problems. + +19:29.640 --> 19:33.200 +First, it allowed me to implement + +19:33.300 --> 19:37.280 +non-trivial analysis and transformations, + +19:37.380 --> 19:40.000 +the ones I needed in my compiler pipeline. + +19:40.100 --> 19:42.160 +But also, it solved the problem of + +19:42.260 --> 19:43.840 +what was the boundary between + +19:43.940 --> 19:46.120 +what I had to implement in Lisp, + +19:46.220 --> 19:48.040 +and what in C. + +19:48.140 --> 19:49.040 +Because once I had + +19:49.140 --> 19:51.860 +my intermediate representation defined, + +19:51.960 --> 19:53.780 +essentially the boundary between Lisp and C + +19:53.880 --> 19:55.640 +is just a function, that is, + +19:55.740 --> 19:57.780 +the one that is implementing the final pass. + +19:57.880 --> 19:59.220 +That is taking, as an input, + +19:59.320 --> 20:01.620 +all of my programs in LIMPLE representation + +20:01.720 --> 20:03.880 +and it's doing [his bit]. + +20:03.980 --> 20:07.980 +So I was convinced this design at least had sense. + +20:08.080 --> 20:10.120 +When we go through some of these passes, + +20:10.220 --> 20:12.600 +just to give you an idea of what these are doing: + +20:12.700 --> 20:14.560 +the first pass is just responsible for + +20:14.660 --> 20:18.100 +spilling the LAP from the byte compiler + +20:18.200 --> 20:20.160 +that effectively here we are using as a front end + +20:20.260 --> 20:21.780 +for our compiler pipeline. + +20:21.880 --> 20:24.040 +The second pass, called 'limplify', + +20:24.140 --> 20:27.920 +will be in charge of converting LAP into LIMPLE. + +20:28.020 --> 20:31.260 +LIMPLE is an intermediate representation + +20:31.360 --> 20:32.860 +that is Control Flow Graph based, + +20:32.960 --> 20:34.700 +and it's capable of SSA. + +20:34.800 --> 20:38.640 +So we can have a look to what this means. + +20:38.740 --> 20:41.300 +Let's assume we have our LAP program, + +20:41.400 --> 20:42.520 +as any program, + +20:42.620 --> 20:43.960 +that's a simple list of instructions + +20:44.060 --> 20:45.640 +that we will execute one after the other. + +20:45.740 --> 20:47.360 +Some of these instructions + +20:47.460 --> 20:49.200 +are special instructions + +20:49.300 --> 20:51.240 +that we call conditional branches, + +20:51.340 --> 20:52.800 +where we check for a condition, + +20:52.900 --> 20:54.320 +and if this is verified, + +20:54.420 --> 20:56.940 +we jump to a different address within the program. + +20:57.040 --> 20:59.580 +(Addresses that here we are calling 'labels'.) + +20:59.680 --> 21:03.440 +So we can split our program in chunks, + +21:03.540 --> 21:08.200 +and those chunks we execute without interruption, + +21:08.300 --> 21:10.460 +so we always enter from the top of those, + +21:10.560 --> 21:12.600 +and we exit from the bottom. + +21:12.700 --> 21:15.980 +We can name those, and split them apart, + +21:16.080 --> 21:18.980 +and these are what we call basic blocks. + +21:19.080 --> 21:22.360 +And now we have a bunch of these basic blocks + +21:22.460 --> 21:23.380 +that are floating, + +21:23.480 --> 21:25.020 +and they are not any more sorted. + +21:25.120 --> 21:25.920 +This is what is called + +21:26.020 --> 21:28.680 +a Control Flow Graph based representation. + +21:28.780 --> 21:31.400 +Now we can get into the SSA topic. + +21:31.500 --> 21:33.900 +That stands for Static Single Assignment. + +21:34.000 --> 21:35.860 +I don't want to get into the details, + +21:35.960 --> 21:36.720 +but just give you a feeling. + +21:36.820 --> 21:38.480 +I added into our basic blocks + +21:38.580 --> 21:41.400 +in our Control Flow Graph a few assignments. + +21:41.500 --> 21:43.840 +We will transform this into SSA + +21:43.940 --> 21:45.040 +just for the variable 'x', + +21:45.140 --> 21:47.360 +just for the sake of demonstrating it. + +21:47.460 --> 21:49.760 +This is done through a number of phases + +21:49.860 --> 21:51.760 +that are essentially some analysis, + +21:51.860 --> 21:52.600 +mainly renaming. + +21:52.700 --> 21:55.560 +But the outcome, the one we see here, + +21:55.660 --> 21:59.120 +looks quite similar to the original one, + +21:59.220 --> 22:01.120 +but we can see that the variable 'x' + +22:01.220 --> 22:01.960 +has been renamed. + +22:02.060 --> 22:03.400 +And now we don't have anymore just one, + +22:03.500 --> 22:06.140 +but a number of these variables. + +22:06.240 --> 22:08.000 +The interesting property is that + +22:08.100 --> 22:10.880 +each of these variables is assigned just once. + +22:10.980 --> 22:13.240 +And this allows for the compiler + +22:13.340 --> 22:16.760 +to do prediction of the value of that variable, + +22:16.860 --> 22:19.040 +depending on the position + +22:19.140 --> 22:19.840 +within the Control Flow Graph. + +22:19.940 --> 22:21.980 +This is very important. For instance, + +22:22.080 --> 22:23.440 +a very simple case is 'x1' + +22:23.540 --> 22:27.440 +that we see is assigned once by definition, + +22:27.540 --> 22:29.300 +in particular here at the beginning. + +22:29.400 --> 22:31.040 +Here it's very simple to understand + +22:31.140 --> 22:33.080 +that x1 will have the value 3. + +22:33.180 --> 22:35.380 +While, for instance, it's more difficult to prove + +22:35.480 --> 22:37.060 +what is going to be the value of x5, + +22:37.160 --> 22:38.620 +because it's calling a function, + +22:38.720 --> 22:41.940 +or we don't know at the moment what x4 is. + +22:42.040 --> 22:46.240 +So the compiler will gain the capability + +22:46.340 --> 22:48.460 +to do prediction on all the variables, + +22:48.560 --> 22:50.620 +and the more we get information on one variable, + +22:50.720 --> 22:54.980 +the more we can prove about the others. + +22:55.460 --> 22:57.280 +Coming back to our passes, the next one + +22:57.380 --> 22:59.320 +is forward propagation. + +22:59.420 --> 23:00.600 +This pass is responsible for + +23:00.700 --> 23:03.240 +doing what I briefly mentioned just before: + +23:03.340 --> 23:07.160 +doing proof over all the different variables + +23:07.260 --> 23:09.620 +in different positions of the Control Flow Graph, + +23:09.720 --> 23:12.700 +about the values, types, or ranges. + +23:12.800 --> 23:15.080 +This pass is also responsible for + +23:15.180 --> 23:16.920 +executing functions + +23:17.020 --> 23:18.640 +when we know that the function has no side effect + +23:18.740 --> 23:20.520 +and the pass managed to + +23:20.620 --> 23:22.440 +prove all the values of its argument. + +23:22.540 --> 23:24.800 +So the function is then executed at compile time + +23:24.900 --> 23:26.700 +and it doesn't even exist anymore + +23:26.800 --> 23:27.880 +in the produced code. + +23:27.980 --> 23:30.300 +Then we have another pass, this is + +23:30.400 --> 23:33.420 +an example of a pass that is very specific: + +23:33.520 --> 23:36.120 +it's trying to remove the call to funcall + +23:36.220 --> 23:38.040 +when those are not necessary. + +23:38.140 --> 23:39.760 +There are a couple situations + +23:39.860 --> 23:42.200 +where this is very useful. + +23:42.300 --> 23:45.240 +And not only is this beneficial + +23:45.340 --> 23:47.560 +because we are generating better code, + +23:47.660 --> 23:49.245 +but when we manage to do that, + +23:49.345 --> 23:52.000 +we allow GCC better analysis over the code, + +23:52.100 --> 23:54.440 +because GCC knows nothing about funcall. + +23:54.540 --> 23:57.400 +So if we are calling, from 'foo', directly, 'bar', + +23:57.500 --> 24:01.280 +for GCC it's way easier to do its analysis + +24:01.380 --> 24:03.360 +on top of this code. + +24:03.460 --> 24:06.240 +Another interesting pass we can mention is 'tco'. + +24:06.340 --> 24:08.800 +This is performing Tail Recursion Elimination. + +24:08.900 --> 24:11.880 +It allows a more functional programming style, + +24:11.980 --> 24:13.220 +if you want. + +24:13.320 --> 24:14.280 +We can jump to the last pass + +24:14.380 --> 24:16.200 +that is called 'final', and as I mentioned, + +24:16.300 --> 24:17.520 +this one is responsible for + +24:17.620 --> 24:19.880 +taking our program in LIMPLE representation + +24:19.980 --> 24:24.900 +and describing it to libgccjit in the gccjit IR. + +24:25.000 --> 24:27.480 +That's the main task. It's also + +24:27.580 --> 24:29.520 +defining inline functions + +24:29.620 --> 24:32.400 +for accessing fundamental data types, and so on. + +24:32.500 --> 24:34.460 +This pass is also responsible for + +24:34.560 --> 24:36.280 +using some of the predictions + +24:36.380 --> 24:39.560 +done by previous passes to generate better code. + +24:39.660 --> 24:41.320 +Things we had to add + +24:41.420 --> 24:43.880 +to have all of this machinery work + +24:43.980 --> 24:45.240 +and to be controllable: + +24:45.340 --> 24:47.480 +The first one is an opt called 'native-comp-speed' + +24:47.580 --> 24:49.920 +and it's equivalent to Common Lisp's 'speed'. + +24:50.020 --> 24:51.920 +It represents the optimization level. + +24:52.020 --> 24:53.400 +The default is 2 and is + +24:53.500 --> 24:55.400 +the maximum optimization level + +24:55.500 --> 24:58.600 +that is meant to reflect + +24:58.700 --> 25:00.860 +all the original semantics of Emacs Lisp. + +25:00.960 --> 25:02.480 +So it's the one that should be used by default. + +25:02.580 --> 25:04.640 +The second one is 'compilation unit' + +25:04.740 --> 25:05.960 +and it's a kind of new object + +25:06.060 --> 25:11.080 +that has been added to Emacs. + +25:11.180 --> 25:12.960 +Let's have a look to + +25:13.060 --> 25:14.360 +how the Garbage Collector works in this case. + +25:14.460 --> 25:15.840 +The GNU Emacs Garbage Collector + +25:15.940 --> 25:18.660 +is a simple mark-and-sweep garbage collector. + +25:18.760 --> 25:21.420 +It does a tree walk through all the objects + +25:21.520 --> 25:25.100 +and follows references from one object to another. + +25:25.200 --> 25:27.960 +All the objects reachable during the mark phase + +25:28.060 --> 25:31.240 +will be kept in our Lisp universe. + +25:31.340 --> 25:33.680 +All the other ones will be freed. + +25:33.780 --> 25:35.080 +In this case we have a bunch of functions, + +25:35.180 --> 25:38.760 +'foo1', 'foo2', 'bar1', etc., that are defined. + +25:38.860 --> 25:40.320 +When a function is defined, + +25:40.420 --> 25:42.400 +it's accessible through its symbol, + +25:42.500 --> 25:44.360 +so we have the symbol referring to the function. + +25:44.460 --> 25:47.720 +The function, in this case a native-compiled one, + +25:47.820 --> 25:50.040 +is referring to the compilation unit. + +25:50.140 --> 25:53.020 +The compilation unit is essentially + +25:53.120 --> 25:58.600 +the ELF file that has been compiled, + +25:58.700 --> 26:01.160 +and contains all those functions + +26:01.260 --> 26:03.240 +that came from the original .el file, + +26:03.340 --> 26:05.100 +and that we have loaded into memory. + +26:05.200 --> 26:10.000 +If, for instance, 'bar1 and 'bar2 are undefined, + +26:10.100 --> 26:14.200 +functions [3] and 4 will be no longer reachable, + +26:14.300 --> 26:16.040 +and we will be able to free them + +26:16.140 --> 26:18.160 +and unload the compilation unit. + +26:18.260 --> 26:21.200 +We discussed quite a lot about Control Flow Graph, + +26:21.300 --> 26:23.560 +SSA, and a lot of boring stuff, + +26:23.660 --> 26:25.400 +and I promised you that we are doing + +26:25.500 --> 26:27.320 +a lot of interesting proofs over variables, + +26:27.420 --> 26:30.220 +So let's have some examples of them. + +26:30.320 --> 26:31.840 +Let's jump into a quick demo + +26:31.940 --> 26:34.480 +to see what all of this abstract theory + +26:34.580 --> 26:37.680 +and this esoteric propagation engine can do for us + +26:37.780 --> 26:39.240 +and how the user can interact with it. + +26:39.340 --> 26:42.100 +I've defined a bunch of functions, + +26:42.200 --> 26:45.240 +and I will native-compile and load it. + +26:47.500 --> 26:48.840 +Alright, Emacs Lisp native compiled and loaded. + +26:48.940 --> 26:52.320 +At this point, I can disassemble 'foo1' + +26:52.420 --> 26:56.320 +to make sure it's native code and I'm not lying. + +26:56.420 --> 26:58.500 +These are the instructions + +26:58.600 --> 27:01.320 +that will be executed directly by my CPU + +27:01.420 --> 27:03.620 +when I call this function. + +27:03.720 --> 27:07.520 +Alright, very cool. + +27:07.620 --> 27:16.080 +Now, [Lisp:] (symbol-function #'foo1) + +27:16.180 --> 27:19.720 +Interestingly, this is returning a subroutine, + +27:19.820 --> 27:21.820 +as it would be a primitive function. + +27:21.920 --> 27:23.700 +Because this is native code, + +27:23.800 --> 27:24.840 +even if it's written in Lisp, + +27:24.940 --> 27:26.340 +has been converted to native code + +27:26.440 --> 27:29.200 +as if it's a primitive function. + +27:29.300 --> 27:31.560 +But we can do also a new thing: + +27:31.660 --> 27:34.440 +asking for the type of the subroutine. + +27:34.540 --> 27:38.360 +Alright, very cool. It says this is a function, + +27:38.460 --> 27:40.280 +it's taking one argument of type 't' + +27:40.380 --> 27:41.560 +(that means anything + +27:41.660 --> 27:42.960 +because we don't have any information), + +27:43.060 --> 27:45.200 +and is returning a type 't', + +27:45.300 --> 27:47.380 +so also there we don't have much information. + +27:47.480 --> 27:49.700 +OK, very cool, but not very useful. + +27:49.800 --> 27:53.680 +Let's see #'foo2. #'foo2 is slightly different, + +27:53.780 --> 27:55.840 +it doesn't take any argument, but it's returning + +27:55.940 --> 27:58.040 +an integer included between 3 and 3. + +27:58.140 --> 28:01.360 +Wow, amazing! + +28:01.460 --> 28:04.040 +Let's get into something a little more complex: + +28:04.140 --> 28:09.440 +#'foo3 takes one argument we know nothing about, + +28:09.540 --> 28:11.740 +but it's returning a number. + +28:11.840 --> 28:13.280 +And why it's returning a number? + +28:13.380 --> 28:16.320 +Essentially because 1+ is returning a number, + +28:16.420 --> 28:18.880 +and in all the other cases, + +28:18.980 --> 28:20.640 +it would signal an error + +28:20.740 --> 28:23.380 +if it's not happy about its input argument. + +28:23.480 --> 28:27.760 +Let's have a look to #'foo4. + +28:27.860 --> 28:32.920 +#'foo4 is a little bit more complex. + +28:33.020 --> 28:34.680 +It will return nil + +28:34.780 --> 28:37.400 +if the 'when' condition is not satisfied, + +28:37.500 --> 28:39.720 +so it's type 'null' here. + +28:39.820 --> 28:41.200 +It can return a floating point; + +28:41.300 --> 28:43.600 +we don't do propagation of floating point so far, + +28:43.700 --> 28:47.080 +or it can return any integer between 4 and 9. + +28:47.180 --> 28:52.840 +Wow. Let's go on with #'foo5. + +28:52.940 --> 28:55.760 +#'foo5 is even more complex + +28:55.860 --> 28:57.200 +because other than + +28:57.300 --> 28:59.180 +having to satisfy this condition, + +28:59.280 --> 29:02.280 +we can see that the result of the propagation + +29:02.380 --> 29:03.800 +of this complex condition + +29:03.900 --> 29:05.460 +is propagated also across the 'plus'. + +29:05.560 --> 29:08.240 +So this foo5 can return nil, + +29:08.340 --> 29:09.720 +a floating point we know nothing about, + +29:09.820 --> 29:13.560 +or an integer included between 12 and 24. + +29:13.660 --> 29:18.080 +Let's go on with #'foo6. + +29:18.180 --> 29:23.320 +#'foo6 is returning anything but an integer. + +29:23.420 --> 29:26.520 +I think it should be pretty obvious why, + +29:26.620 --> 29:28.120 +because if it's not an integer we return it, + +29:28.220 --> 29:30.000 +otherwise we signal an error. + +29:30.100 --> 29:32.880 +Let's finish with #'foo7 very quickly. + +29:32.980 --> 29:37.920 +#'foo7 has another very complex condition, + +29:38.020 --> 29:40.320 +at least for me, but it's also interesting to see + +29:40.420 --> 29:42.200 +that we are also propagating values for symbols. + +29:42.300 --> 29:45.160 +So we can return the symbol 'big, + +29:45.260 --> 29:46.980 +the symbol 'small, + +29:47.080 --> 29:51.200 +or an integer included between -100 and 100. + +29:51.300 --> 29:54.440 +Now, the question is: why all of this is useful + +29:54.540 --> 29:56.800 +other than having Andrea very happy + +29:56.900 --> 29:59.560 +when he's playing with this all day? + +29:59.660 --> 30:01.440 +Well, we have to come back one second + +30:01.540 --> 30:04.920 +to how Lisp_Objects are represented within Emacs. + +30:05.020 --> 30:09.480 +Lisp_Objects are represented as machine words, + +30:09.580 --> 30:12.580 +where we reserve a few bits to indicate the type. + +30:12.680 --> 30:15.560 +And every time we access the object, + +30:15.660 --> 30:17.120 +when this is a Fixnum, + +30:17.220 --> 30:19.920 +or a regular object where this is a pointer, + +30:20.020 --> 30:21.600 +we always have to extract these bits, + +30:21.700 --> 30:24.520 +make sure that they satisfy a condition, + +30:24.620 --> 30:27.120 +so make sure that we are going to manipulate + +30:27.220 --> 30:28.580 +the object of the type we expect, + +30:28.680 --> 30:31.040 +and then we can extract the object + +30:31.140 --> 30:32.540 +and do the manipulation. + +30:32.640 --> 30:34.420 +If the compiler managed to prove + +30:34.620 --> 30:37.400 +that the contained object is of the right type, + +30:37.500 --> 30:42.440 +it will be able to not emit the type check, + +30:42.540 --> 30:44.500 +and save a lot of instructions. + +30:44.600 --> 30:48.560 +This is a very powerful optimization. + +30:48.660 --> 30:50.760 +Let's discuss some potential future development + +30:50.860 --> 30:52.000 +in this area. + +30:52.100 --> 30:53.360 +First I think it would be extremely nice + +30:53.460 --> 30:54.920 +to extend the propagation + +30:55.020 --> 30:56.920 +to types that are not built in. + +30:57.020 --> 30:58.160 +There are a lot of cases + +30:58.260 --> 31:00.600 +where we could optimize effectively. + +31:00.700 --> 31:02.520 +For instance when we do + +31:02.620 --> 31:05.720 +a lot of accesses to structures + +31:05.820 --> 31:06.920 +-- lots of stuff like that -- + +31:07.020 --> 31:08.880 +where we keep on checking and checking + +31:08.980 --> 31:10.640 +the same object for the type + +31:10.740 --> 31:13.080 +where it's obvious, where it should be trivial + +31:13.180 --> 31:14.720 +to prove that it's the right type + +31:14.820 --> 31:16.360 +after the first access or things like that. + +31:16.460 --> 31:18.920 +So I believe this is a low-hanging fruit + +31:19.020 --> 31:21.180 +in terms of performance. + +31:21.280 --> 31:23.080 +Also I think it would be really nice + +31:23.180 --> 31:24.720 +to extend the declare mechanism + +31:24.820 --> 31:27.600 +to allow the user to declare argument types. + +31:27.700 --> 31:30.480 +(Optionally. Indeed, optionally.) + +31:30.580 --> 31:32.880 +Doing that would give the compiler + +31:32.980 --> 31:35.120 +a lot of information to propagate value types + +31:35.220 --> 31:36.360 +within the function. + +31:36.460 --> 31:38.840 +But those will allow the compiler + +31:38.940 --> 31:43.040 +to give the user really good diagnostics + +31:43.140 --> 31:45.400 +during compile time. Like the compiler could say: + +31:45.500 --> 31:47.000 +Hey, here you are calling a function + +31:47.100 --> 31:49.200 +that is expecting this argument of this type, + +31:49.300 --> 31:52.000 +but I'm proving that you are calling it + +31:52.100 --> 31:55.200 +with an argument that is of THIS type, + +31:55.300 --> 31:57.840 +and is not a subtype of the expected one. + +31:57.940 --> 32:00.240 +So you are doing something not coherent. + +32:00.340 --> 32:02.800 +This kind of interprocedural logic. + +32:02.900 --> 32:05.000 +And I think the compiler should also take advantage + +32:05.100 --> 32:06.640 +(under certain circumstances) + +32:06.740 --> 32:08.760 +of this interprocedural analysis + +32:08.860 --> 32:12.520 +in order to optimize even more, when possible. + +32:12.620 --> 32:13.720 +Also I think we should + +32:13.820 --> 32:15.480 +work on our [?] to improve the code generation + +32:15.580 --> 32:17.100 +depending on the prediction + +32:17.200 --> 32:18.160 +that the compiler is doing. + +32:18.260 --> 32:20.120 +We already take advantage of those predictions, + +32:20.220 --> 32:22.300 +but I think we could do better. + +32:22.400 --> 32:25.120 +A quick look at some performance results. + +32:25.220 --> 32:28.720 +These are from the elisp-benchmarks package + +32:28.820 --> 32:30.760 +within GNU ELPA. + +32:30.860 --> 32:32.520 +This is the performance uplift, + +32:32.620 --> 32:38.480 +and we can identify about 4 "classes" of results. + +32:38.580 --> 32:41.440 +The first one there is no performance uplift, + +32:41.540 --> 32:42.880 +because there is not much we can do, + +32:42.980 --> 32:44.720 +and the time is probably not spent + +32:44.820 --> 32:46.280 +within the execution engine. + +32:46.380 --> 32:49.000 +And the ones around 3x are the ones + +32:49.100 --> 32:50.680 +Where probably we are not triggering + +32:50.780 --> 32:52.640 +manually specific optimizations, + +32:52.740 --> 32:53.600 +but just the fact + +32:53.700 --> 32:57.100 +that we are converting into native code + +32:57.200 --> 33:00.500 +is giving us this performance uplift. + +33:00.600 --> 33:03.280 +Then there is a bunch of other benchmarks + +33:03.380 --> 33:05.680 +where the Lisp optimizations are triggering, + +33:05.780 --> 33:09.620 +and the uplift is way bigger, + +33:09.720 --> 33:11.900 +and then we have 3 benchmarks that at the time + +33:12.000 --> 33:13.420 +are completely optimized out. + +33:13.520 --> 33:15.580 +That means the compiler became "so smart" + +33:15.680 --> 33:18.160 +that it was able to compute the result + +33:18.260 --> 33:20.160 +in the compile time and just put the result + +33:20.260 --> 33:21.400 +in the generated binary. + +33:21.500 --> 33:23.880 +Let's discuss a little bit the compilation model. + +33:23.980 --> 33:26.080 +This is an Hybrid one; + +33:26.180 --> 33:29.420 +it's both JIT-like and Ahead-of-Time-like. + +33:29.520 --> 33:33.400 +Emacs is composed of what we call an Emacs image, + +33:33.500 --> 33:36.180 +essentially the Emacs binary that we start. + +33:36.280 --> 33:37.720 +It's including all the C code, + +33:37.820 --> 33:41.760 +plus all the Lisp code that we preload. + +33:41.860 --> 33:46.480 +Then we have the rest of the Emacs Lisp codebase + +33:46.580 --> 33:49.440 +that can be loaded just if it's required. + +33:49.540 --> 33:52.760 +Same for the external packages, if we have any. + +33:52.860 --> 33:55.120 +If we build an Emacs Lisp + +33:55.220 --> 33:57.940 +with native compilation enabled, by default, + +33:58.040 --> 34:01.200 +only the Emacs image will be native compiled. + +34:01.300 --> 34:03.920 +All the other code will be compiled + +34:04.020 --> 34:06.720 +on the fly when it's loaded and executed + +34:06.820 --> 34:08.800 +the first time, if it's necessary. + +34:08.900 --> 34:10.880 +Same for the packages, in a transparent way + +34:10.980 --> 34:12.640 +and asynchronous way. + +34:12.740 --> 34:13.480 +Also worth noting + +34:13.580 --> 34:15.400 +that the result of this compilation + +34:15.500 --> 34:17.240 +will be stored into a cache directory + +34:17.340 --> 34:19.900 +within the home directory of the user. + +34:20.000 --> 34:23.600 +So it will be reused in the following sessions + +34:23.700 --> 34:25.440 +if the same file is loaded, + +34:25.540 --> 34:27.520 +without having to recompile multiple times + +34:27.620 --> 34:29.320 +the same file in different sessions. + +34:29.420 --> 34:31.520 +It works a little bit like this: + +34:31.620 --> 34:33.800 +When we load the byte-code for the first time, + +34:33.900 --> 34:35.900 +we spawn a native compilation process. + +34:36.000 --> 34:39.320 +Meanwhile we keep using the byte-code available. + +34:39.420 --> 34:41.180 +When the native compilation is finished, + +34:41.280 --> 34:43.960 +we hot-swap the definition of the functions + +34:44.060 --> 34:46.040 +that are contained in the file + +34:46.140 --> 34:47.960 +and start using the native code transparently. + +34:48.060 --> 34:49.880 +We do this asynchronously, + +34:49.980 --> 34:53.140 +and for more compilation units at the same time, + +34:53.240 --> 34:56.280 +so it looks a little bit like this. + +34:56.380 --> 34:58.560 +Let's try a quick demo of all of this machinery. + +34:58.660 --> 35:00.880 +I've started a fresh Emacs + +35:00.980 --> 35:03.280 +with native compilation support, + +35:03.380 --> 35:05.060 +and at this moment nothing is going on. + +35:05.160 --> 35:07.440 +We will test the machinery with Tetris, + +35:07.540 --> 35:10.460 +because I can't imagine anything better + +35:10.560 --> 35:12.840 +to test this. + +35:12.940 --> 35:15.080 +What I do expect is that when I launch Tetris + +35:15.180 --> 35:17.920 +it will be loaded, it will immediately + +35:18.020 --> 35:20.460 +start execution of the byte-compiled version, + +35:20.560 --> 35:23.000 +so we won't see any delay in the user experience, + +35:23.100 --> 35:25.160 +and in the meanwhile, a parallel process + +35:25.260 --> 35:28.160 +will start to native-compile Tetris itself. + +35:28.260 --> 35:30.200 +When the native compilation will be finished, + +35:30.300 --> 35:33.240 +the functions of all Tetris will be hot-swapped. + +35:33.340 --> 35:36.280 +So we will not see any interruption. + +35:36.380 --> 35:39.680 +So Tetris started, and it's running, + +35:39.780 --> 35:41.600 +we have seen no delay, and in the meanwhile, + +35:41.700 --> 35:43.520 +the native compilation probably already finished, + +35:43.620 --> 35:44.960 +we can have a look. + +35:45.060 --> 35:47.160 +In this I see the native compilation log buffer. + +35:47.260 --> 35:49.720 +So we see that Tetris has been native compiled, + +35:49.820 --> 35:51.760 +and all of its dependencies. + +35:51.860 --> 35:53.840 +Now Tetris is still running, + +35:53.940 --> 36:00.480 +but I can do "C-h f tetris" + +36:00.580 --> 36:02.540 +and we can see that 'tetris' + +36:02.640 --> 36:04.880 +is an interactive native compiled + +36:04.980 --> 36:07.940 +Lisp function, so it has been native-compiled. + +36:08.040 --> 36:13.500 +I can even disassemble if I want. + +36:13.600 --> 36:14.880 +OK, so very cool. + +36:14.980 --> 36:18.020 +I guess we can say this mechanism is working. + +36:18.120 --> 36:20.660 +Also worth noting that if I go back + +36:20.760 --> 36:24.120 +to the *Async-native-compile-log* buffer, + +36:24.220 --> 36:27.960 +we see we have compiled another bunch of files. + +36:28.060 --> 36:31.600 +I think these are because of my 'C-h f', + +36:31.700 --> 36:33.800 +this help function command and disassemble, + +36:33.900 --> 36:34.920 +and so on. + +36:35.020 --> 36:37.720 +The first time you run Emacs, you will have, + +36:37.820 --> 36:41.280 +from time to time, these processes spawned. + +36:41.380 --> 36:43.100 +Emacs is "compiling itself", + +36:43.200 --> 36:45.520 +and it's replacing the byte-code definition + +36:45.620 --> 36:47.640 +with the native one. But after a few sessions, + +36:47.740 --> 36:49.760 +you will not see this anymore, + +36:49.860 --> 36:51.360 +because the output of this compilation, + +36:51.460 --> 36:54.900 +as I mentioned, are stored in the user directory. + +36:55.000 --> 36:57.560 +To conclude: Emacs with native compilation support + +36:57.660 --> 36:59.080 +is coming up in Emacs 28, + +36:59.180 --> 37:01.040 +that is gonna be the next major stable release + +37:01.140 --> 37:02.080 +that will be released. + +37:02.180 --> 37:04.840 +So we ought to celebrate with a big party, + +37:04.940 --> 37:07.320 +I believe. But before going to the party, + +37:07.420 --> 37:09.080 +I'd like to list a few points + +37:09.180 --> 37:11.340 +that I think have been success factors + +37:11.440 --> 37:13.420 +in upstreaming this work. + +37:13.520 --> 37:15.420 +It has been extremely important + +37:15.520 --> 37:18.140 +to get in touch with upstream as soon as possible, + +37:18.240 --> 37:20.680 +as soon as I had a proof of concept. + +37:20.780 --> 37:22.600 +It's been extremely important + +37:22.700 --> 37:24.660 +to involve the community as much as possible, + +37:24.760 --> 37:28.480 +and this included keeping a development blog, + +37:28.580 --> 37:31.600 +and posts about that on emacs-devel, + +37:31.700 --> 37:33.720 +and also producing material, + +37:33.820 --> 37:36.020 +participating in conferences, + +37:36.120 --> 37:38.320 +and giving presentations like the one I'm doing, + +37:38.420 --> 37:40.680 +to explain what I was doing and how it works. + +37:40.780 --> 37:43.040 +It has been extremely important, also, + +37:43.140 --> 37:45.860 +to be able to rely on the upstream infrastructure. + +37:45.960 --> 37:47.540 +So, to develop the software + +37:47.640 --> 37:49.080 +as a feature branch in the official git, + +37:49.180 --> 37:49.960 +but even more, I would say, + +37:50.060 --> 37:51.660 +to use the official bug tracker + +37:51.760 --> 37:52.880 +for solving bugs of this branch. + +37:52.980 --> 37:54.680 +This gave the opportunity + +37:54.780 --> 37:58.160 +to stay really in close touch with maintainers, + +37:58.260 --> 37:59.920 +and senior developers of Emacs. + +38:00.020 --> 38:02.980 +That helped me a lot. And at the same time + +38:03.080 --> 38:04.820 +they were informed about what I was doing + +38:04.920 --> 38:07.360 +and what was the status of this feature branch. + +38:07.460 --> 38:08.800 +Extremely important. + +38:08.900 --> 38:11.160 +And also I think it played a major role + +38:11.260 --> 38:14.120 +to try to design this enormous patch + +38:14.220 --> 38:18.120 +in a way that the impact on the current codebase + +38:18.220 --> 38:21.120 +was minimized (at least as much as possible). + +38:21.220 --> 38:23.660 +And also minimizing + +38:23.760 --> 38:26.240 +the impact on the user operation of the software, + +38:26.340 --> 38:28.040 +in this case Emacs. + +38:28.140 --> 38:29.640 +So yes, mandatory Special Thanks: + +38:29.740 --> 38:33.360 +Emacs developers, and especially maintainers + +38:33.460 --> 38:36.680 +and senior developers like Stefan Monnier, + +38:36.780 --> 38:40.440 +that helped me a lot across this long journey. + +38:40.540 --> 38:42.800 +And, well, all the community + +38:42.900 --> 38:45.160 +that really got so excited about this project + +38:45.260 --> 38:46.240 +and gave me the energy + +38:46.340 --> 38:49.120 +to go through all of this time and development + +38:49.220 --> 38:51.980 +and bugs and solving, etc. etc. + +38:52.080 --> 38:54.920 +So yes, it was a really exciting time, + +38:55.020 --> 38:58.000 +and I think we have to look forward + +38:58.100 --> 39:01.400 +and start thinking about how to improve all this + +39:01.500 --> 39:02.920 +for the following years. + +39:03.020 --> 39:04.300 +And that's it. + +39:04.400 --> 39:06.040 +I think I should be online for questions. + +39:06.140 --> 39:07.480 +Thank you very much. + +39:07.580 --> 39:07.680 +[captions by John Cummings] diff --git a/2021/captions/emacsconf-2021-news--emacs-news-highlights--sacha-chua--main--chapters.vtt b/2021/captions/emacsconf-2021-news--emacs-news-highlights--sacha-chua--main--chapters.vtt new file mode 100644 index 00000000..7afd1e04 --- /dev/null +++ b/2021/captions/emacsconf-2021-news--emacs-news-highlights--sacha-chua--main--chapters.vtt @@ -0,0 +1,34 @@ +WEBVTT + +00:00:00.003 --> 00:00:11.023 +Introduction + +00:00:11.024 --> 00:00:24.987 +Upcoming Emacs 28 release + +00:00:24.988 --> 00:00:57.125 +Org mode 9.5 + +00:00:57.126 --> 00:01:18.107 +Magit major release + +00:01:18.108 --> 00:01:51.283 +Completion + +00:01:51.284 --> 00:02:12.064 +Embark + +00:02:12.065 --> 00:02:44.655 +tree-sitter + +00:02:44.656 --> 00:03:03.656 +Collaborative editing + +00:03:03.657 --> 00:03:41.737 +Graphical experiments + +00:03:41.738 --> 00:04:00.070 +Community + +00:04:00.071 --> 00:04:01.071 +libera.chat diff --git a/2021/captions/emacsconf-2021-omegat--emacs-manuals-translation-and-omegat--jean-christophe-helary--main--chapters.vtt b/2021/captions/emacsconf-2021-omegat--emacs-manuals-translation-and-omegat--jean-christophe-helary--main--chapters.vtt new file mode 100644 index 00000000..51d6ae42 --- /dev/null +++ b/2021/captions/emacsconf-2021-omegat--emacs-manuals-translation-and-omegat--jean-christophe-helary--main--chapters.vtt @@ -0,0 +1,31 @@ +WEBVTT

We welcome speakers of *all backgrounds* and + *all levels of experience*, including newcomers giving their first + talk. What have you found exciting about Emacs lately? What do you + wish someone had told you when you were starting out? What part of + your workflow might inspire someone to get into Emacs or go deeper? + + A great way to get started with writing a proposal is to start by + exploring the programs from previous years: [[https://emacsconf.org/2020/schedule/][2020]], [[https://emacsconf.org/2019/schedule/][2019]], [[https://emacsconf.org/2015/schedule/][2015]], [[https://emacsconf.org/2013/#program][2013]]. + You might also find some neat ideas on the [[https://emacsconf.org/2021/ideas/][ideas]] page. Feel free to + add yours there too! If you're still not sure, come by our IRC + channel =#emacsconf= on =irc.libera.chat= and say hi. You can join + the chat using [[ircs://irc.libera.chat:6697/emacsconf][your favourite IRC client]], or by visiting + [[https://chat.emacsconf.org][chat.emacsconf.org]] in your web browser. + + All kinds of people use Emacs for all kinds of things. We'd love it + if EmacsConf 2021 could highlight interesting perspectives and reflect + the diversity of our community. If you know someone who might have a + good idea for a talk, please reach out to them and encourage them to + submit a proposal. Many people (especially from underrepresented + groups such as women, people of colour, non-developers, etc.) might + not consider themselves expert enough to share their thoughts. If you + let them know that you value their knowledge and maybe even suggest + something that you think others would like to hear more about, they + may realize that they have something worth sharing and that we would + love to hear from them. + + * Important dates + + For EmacsConf 2021, we are planning for 9am to 5pm Toronto/EST + (2pm-10pm UTC) on November 27 and 28. Depending on people's + availability, it might be two half-days. + + | CFP opens | August 5, 2021 | + | CFP closes | September 30, 2021 | + | Speaker notifications | October 15, 2021 | + | Schedule published | October 31, 2021 | + | EmacsConf 2021! | November 27 and 28, 2021 | + + If you are not available during the conference itself but you have a + neat idea that you'd like to share, please propose it anyway! You can + always handle questions after the conference, and we might even be + able to coordinate with other Emacs meetups for regional events (if + you're an Emacs meetup organizer and would like to make this happen + let's [[https://emacsconf.org/contact/][get in touch]]!). + + Please note that although we will try our best to stick to the above + dates in the coming months, given the current state of the world, we + may have to move things around a bit in case of unforeseen events. + Thank you for your patience and understanding. + + * Talk formats + + We'd like EmacsConf 2021 to inspire lots of different people to + explore lots of different things in Emacs. We hope to put together a + stream of quick ideas followed by lots of conversation over IRC and/or + Q&A sessions, with occasional deep dives into topics that many people + might find interesting or useful. + + As you think about your talk, consider what you can share in: + + - *Up to 10 minutes total:* What is the core idea? What do you want + people to do or remember? You can show just enough to get people + interested and then point them to where they can learn more + afterwards. You can answer questions over IRC, the pad, or the + wiki, and there's no limit to how long that conversation can go. + + - *Up to 20 minutes total:* How would you flesh out some of the points + from your 5-10 minute presentation? How can you show the pieces + working together? + + - *Up to 40 minutes total:* What would benefit from a deep dive? + How do you keep it engaging? + + When writing your proposal, please write an outline of what you plan + to talk about if you have 5-10 minutes. If you'd like to propose a + longer talk, outline what you might include if you had more time to + present (up to 40 minutes, including Q&A). + + Here's an example for a potentially 40-minute talk: + + - 5-10 minutes: quick demo of the abc package working together with + xyz package. + - 20 minutes: same as above, with some customization options to + accommodate a different workflow. + - 40 minutes: all of the above, including modifying the behaviour of + the package in order to add something new. + + This flexibility would help us in devising the conference schedule so + that as many people as possible could get a chance to present their + ideas, while still allowing for featuring longer deep dive talks. + + Other session formats such as tutorials, workshops, and hangouts are + welcome as well, in case you would find those other formats preferable + to a traditional talk format. If you're interested in these or other + session types, please let us know [[https://lists.gnu.org/mailman/listinfo/emacsconf-org][publicly]] or [[https://lists.gnu.org/mailman/listinfo/emacsconf-org-private][privately]]. We'll be + happy to work something out with you. + + * Office hours + + We're aware that it can be intimidating to submit a proposal to a + conference, so we thought we'd try to help! This year, we're opening + up the doors of our virtual offices for you to come talk to us about + your proposals with hopes of helping you with any hurdles you may be + facing with preparing your proposal. + + We'd like to publish a schedule of availabilities of volunteers for + holding office hours. Currently these volunteers consist of some of + the EmacsConf organizers, but we'd love to have the help of other + members of the Emacs community as well. If you are a more experienced + Emacs user and would like to help with this, please [[https://emacsconf.org/contact/][get in touch]]! + + Our first office hour this year is planned for Saturday, August 14, + from 3pm to 4pm UTC with zaeph (Leo Vivier) at the following + BigBlueButton room: https://bbb.emacsverse.org/b/ban-qye-fd1-5kw. + + * Submitting your proposal + + Once you're ready to submit your proposal, the [[https://emacsconf.org/2021/submit/][submit]] page has the + instructions on how to submit your talk. + + We use an anonymized submission process to reduce bias and encourage + contribution. Identifying information will be removed from + submissions by a conference organizer who will not participate in + talk selection. The anonymized submissions will then be reviewed by + a selection committee. + + If your talk is approved, we'd love it if you could help us make sure + the conference runs smoothly. After we email you with the time + allotted for your talk, we'll ask you to + + - prepare a prerecording of your talk, or record it with our help if + that'd be easier for you; and + - schedule a short tech-check if you'd like to be able to answer + questions in a live session. + + Don't forget to subscribe to our main mailing list, [[https://lists.gnu.org/mailman/listinfo/emacsconf-discuss][emacsconf-discuss]], + for discussion and announcements about the EmacsConf conference. + + We look forward to your ideas and submissions! + + * Getting involved + + If you would like to help with the conference (planning the sessions, + reviewing proposals, helping with infrastructure, making sessions more + accessible, editing video transcripts, etc.), see our [[https://emacsconf.org/2021/planning/][planning]] page + and come say hi to us at =#emacsconf= on =irc.libera.chat=. + + In addition to the [[https://lists.gnu.org/mailman/listinfo/emacsconf-discuss][emacsconf-discuss]] list, feel free to subscribe to + [[https://lists.gnu.org/mailman/listinfo/emacsconf-org][emacsconf-org]] as well, for discussions related to organizing the + conference by the EmacsConf organizers and volunteers. + + We'd really appreciate your help in making EmacsConf 2021 the best one + so far! + + * Commitment to freedom + + We remain fully committed to freedom, and we will continue + using our infrastructure and streaming setup consisting entirely + of [[https://www.gnu.org/philosophy/free-sw.html][free software]], much like previous EmacsConf conferences. + An article describing our infrastructure and tools is underway, + and will be announced on the emacsconf-discuss list when published. + + + * COMMENT Copyright & License + + Copyright (c) 2020 Amin Bandali, Sacha Chua, David Bremner + Copyright (c) 2021 Amin Bandali, Sacha Chua, Leo Vivier, + Sebastian Crane + + The EmacsConf 2021 Call for Proposals is part of the EmacsConf wiki, + and is dual-licensed under the terms of the Creative Commons + Attribution-ShareAlike 4.0 International Public License; and the GNU + General Public License as published by the Free Software Foundation, + either version 3 of the License, or (at your option) any later + version. + + A copy of these two licenses is available on the EmacsConf wiki, in + the [[https://emacsconf.org/COPYING.CC-BY-SA][COPYING.CC-BY-SA]] and [[https://emacsconf.org/COPYING.GPL][COPYING.GPL]] files. + + * COMMENT How to export this file + + As of the time of writing this document (Org mode version 9.3.7), the + Org links library (=ol.el=) does not yet recognize =ircs= link types, + and will throw an error if you try to export a file containing them, + such as this file. + + To work around that, you can use something along the lines of the + Emacs Lisp code below, by either adding it to your init file, or by + putting the point in the code block and hitting =C-c C-v e= (that is, + hold Ctrl, then hit c followed by v, then release Ctrl, and hit e) to + evaluate the code, working around the issue only for the current + session. + + #+begin_src emacs-lisp :results silent + (org-link-set-parameters + "ircs" + :export + (lambda (link description format) + "Export an ircs link. + See `org-link-parameters' for details about LINK, DESCRIPTION and + FORMAT." + (let ((desc (or description link))) + (pcase format + (`html (format "<a href=\"ircs:%s\">%s</a>" link desc)) + (`md (format "[%s](ircs:%s)" desc link)) + (_ nil))))) + #+end_src + + +<a id="second-cfp"></a> + +### Second (and final) call for proposals (closing Sep 30) :email: + +Sent Sept 27, 2021 to the same lists as the CFP +Included inline Markdown and attached Org version of the CFP + +- E-mail text + + Dear fellow Emacsians, + + This is the second and final Call for Proposals for EmacsConf 2021, + open until September 30.

The times may +move around a bit as we update the schedule, so we'll check in with +you if things change a lot. We've scheduled a few minutes for live +questions and answers via web conference. Will you be available +around this time? If there are more questions, you can also continue +over Etherpad/IRC. + +Please plan to prerecord your ${duration}-minute talk(s) by ${deadline} +at the latest. If you can, please send it in as early as possible. +Submitting your video early lets us ask volunteers to help caption the +video, making your talk more accessible and searchable. + +Please see <https://emacsconf.org/${conf-year}/prepare/> for tips and +instructions on preparing, recording, and sending in your talk.

I know it's a strange time for everyone, so +no worries if other priorities have come up and you don't have the +time for a presentation. + +If you've been having technical issues recording your presentation on +your computer, one of our volunteers could set up a BigBlueButton web +conference with you to record the presentation. You can find a list of +volunteers and their availability at +<https://emacsconf.org/2021/prepare/#tech-check> . It takes a little time +to get the recording out of BBB, so please plan to record your +presentation before Tuesday, November 23. + +If you plan to present live, please go through the self-check at +<https://test.bigbluebutton.org/> . Some speakers have encountered +technical issues with BigBlueButton that they didn't have with Zoom or +Google Meet, so this is something we definitely want to look into +earlier rather than later. If that works for you, please e-mail us +back so that I can keep your timeslot. The tentative schedule for your +talk is on the talk page at ${url} . + +**Please e-mail us your plans before ${deadline}.** I'm +planning to shift the schedule around to give more time to confirmed +speakers for Q&A and possibly live demos. If I don't hear from you by +then (maybe an over-enthusiastic spam filter has been swallowing up +all our mail?), I'll probably reallocate the 10 minutes that had +been set aside for your talk. We might be able to squeeze it back in +afterwards or play a video from you at the end of the conference day, +but it would be nice to get the schedule sorted out instead of +scrambling to fill gaps on the day of the conference. + +Hope to hear from you by ${deadline}! + +Sacha Chua + +(Please use Reply to All to keep emacsconf-submit@gnu.org in the loop.

A few weeks ago, +we excitedly shared the EmacsConf 201 program with you. We're now +happy to share the conference schedule with you, i.e. the program +plus each talk's (approximate) scheduled time slot: + +<https://emacsconf.org/2021/schedule> + +All of the times listed on the schedule are in EST (UTC-5). You can +click on each talk's title to open its page for more information, +including its scheduled time in your local time (displaying local time +requires running a tiny bit of AGPLv3+-licensed free/libre JavaScript +code, included on the talk pages). For prerecorded talks, this time +is also when the talk's video will be made available on the same page. +Please note the '~' tildes near the times, indicating that they are +approximations and not meant to be taken as exact times. + +On November 27 and 28 you will be able to watch the livestreams via +<https://live.emacsconf.org>, which also has details on how to watch the +streams using media players that support streaming (like mpv and VLC). +Also, for Asia-Pacific folks, there will be an alternate stream by +LibreAustralia, at 11:00-17:30 UTC+11 on Sunday, November 28. Please +see the <https://libreau.org/upcoming.html#emacsconf21> page on their +site for more details and how to tune into the alternate stream. + +Last but not least, please see the <https://emacsconf.org/2021> page +of the EmacsConf wiki for more details on watching and participating +in the conference. + +We hope to see you all around on November 27-28 for EmacsConf 2021! + +Amin Bandali, Leo Vivier, and Sacha Chua, +On behalf of the EmacsConf 2021 organizers team + + +<a id="follow-up-prerecs"></a> + +## Follow up regarding prerecorded videos :email: + +EmacsConf is in a few days and I don't think we have your prerecorded +video yet, so I'm getting miiiildly stressed about the schedule. And +you're probably stressing out about it too, so let's go figure out how +we can make this work. + +Option A: If you happen to have the prerecording or can get it done by +tomorrow, we can probably squeeze it in. Please upload it to +ftp-upload.emacsconf.org by following the instructions in +<https://emacsconf.org/2021/prepare#ftp-upload> , or send us a link using +your favourite file-sharing service (especially if FTP is giving you +problems). + +Option B: If you want to present live, it might be an option. I'm a little +worried about the potential for technical issues, since we've had +problems with that in previous EmacsConfs. The tight schedule means +there's not a lot of time to figure things out, and it can be hard to +make something as focused as a prerecorded video when you're doing it +live. We will definitely want to make sure that: + +- your self-serve tech check works: <https://test.bigbluebutton.org> + at your convenience; +- we have your emergency contact information in case of frozen + Internet connection, etc. Please e-mail us the phone number we can + use to call you. We promise to use it only for EmacsConf 2021 + emergency coordination; and +- you check in as early as possible (at least 1 hour before, so we + know if the speaker before you needs to extend) and let us know + that you want to do it live <https://emacsconf.org/2021/speakers> . + We keep adapting the schedule as things come up, so please check + <https://emacsconf.org/2021/schedule/> on the day of the conference. + +If there are technical issues or your talk runs a little over time, we +might have to stop streaming it on the main stream when it's time for +the next talk. We may be able to continue streaming it on the +alternate stream. If so, people can continue watching it there if they +wish to. + +Option C: If you can't make it, that's okay. Life gets crazy +sometimes. Please let us know and we can update the wiki. If you +happen to be able to make a prerecorded video afterwards, we can add +that to the wiki, playlists, and announcements. We hope you can join +us next year. + +Since EmacsConf is **this weekend** (aaaaaaah), please let us know by +tomorrow noon EST (Friday; 9AM PST, 5PM GMT, 6PM CET) so that we can +keep the time allocated for you in the schedule. If we don't hear from +you, we'll probably reallocate the ${duration} minutes reserved for you so +that other talks can have longer Q&A. If you can still make it, check +in early and let us know so that we can try to work out an alternate +stream for you.

If you'd like to present at the conference, please +[[https://emacsconf.org/2021/cfp/][submit your proposal]] by *September 30, 2021*. + +EmacsConf 2021 is about the joy of [[https://www.gnu.org/software/emacs/][Emacs]] and Emacs Lisp. Come share +your experiments and adventures with the Emacs text editor / operating +system / way of life! We welcome speakers of *all backgrounds* and +*all levels of experience*, including newcomers giving their first +talk. What have you found exciting about Emacs lately? What do you +wish someone had told you when you were starting out? What part of +your workflow might inspire someone to get into Emacs or go deeper? + +A great way to get started with writing a proposal is to start by +exploring the programs from previous years: [[https://emacsconf.org/2020/schedule/][2020]], [[https://emacsconf.org/2019/schedule/][2019]], [[https://emacsconf.org/2015/schedule/][2015]], [[https://emacsconf.org/2013/#program][2013]]. +You might also find some neat ideas on the [[https://emacsconf.org/2021/ideas/][ideas]] page. Feel free to +add yours there too! If you're still not sure, come by our IRC +channel =#emacsconf= on =irc.libera.chat= and say hi. You can join +the chat using [[ircs://irc.libera.chat:6697/emacsconf][your favourite IRC client]], or by visiting +[[https://chat.emacsconf.org][chat.emacsconf.org]] in your web browser. + +All kinds of people use Emacs for all kinds of things. We'd love it +if EmacsConf 2021 could highlight interesting perspectives and reflect +the diversity of our community. If you know someone who might have a +good idea for a talk, please reach out to them and encourage them to +submit a proposal. Many people (especially from underrepresented +groups such as women, people of colour, non-developers, etc.) might +not consider themselves expert enough to share their thoughts. If you +let them know that you value their knowledge and maybe even suggest +something that you think others would like to hear more about, they +may realize that they have something worth sharing and that we would +love to hear from them. + +,* Important dates + +For EmacsConf 2021, we are planning for 9am to 5pm Toronto/EST +(2pm-10pm UTC) on November 27 and 28. Depending on people's +availability, it might be two half-days. + +| CFP opens | August 5, 2021 | +| CFP closes | September 30, 2021 | +| Speaker notifications | October 15, 2021 | +| Schedule published | October 31, 2021 | +| EmacsConf 2021! | November 27 and 28, 2021 | + +If you are not available during the conference itself but you have a +neat idea that you'd like to share, please propose it anyway! You can +always handle questions after the conference, and we might even be +able to coordinate with other Emacs meetups for regional events (if +you're an Emacs meetup organizer and would like to make this happen +let's [[https://emacsconf.org/contact/][get in touch]]!). + +Please note that although we will try our best to stick to the above +dates in the coming months, given the current state of the world, we +may have to move things around a bit in case of unforeseen events. +Thank you for your patience and understanding. + +,* Talk formats + +We'd like EmacsConf 2021 to inspire lots of different people to +explore lots of different things in Emacs. We hope to put together a +stream of quick ideas followed by lots of conversation over IRC and/or +Q&A sessions, with occasional deep dives into topics that many people +might find interesting or useful. + +As you think about your talk, consider what you can share in: + +- *Up to 10 minutes total:* What is the core idea? What do you want + people to do or remember? You can show just enough to get people + interested and then point them to where they can learn more + afterwards.

If you're interested in these or other +session types, please let us know [[https://lists.gnu.org/mailman/listinfo/emacsconf-org][publicly]] or [[https://lists.gnu.org/mailman/listinfo/emacsconf-org-private][privately]]. We'll be +happy to work something out with you. + +,* Office hours + +We're aware that it can be intimidating to submit a proposal to a +conference, so we thought we'd try to help! This year, we're opening +up the doors of our virtual offices for you to come talk to us about +your proposals with hopes of helping you with any hurdles you may be +facing with preparing your proposal. + +We'd like to publish a schedule of availabilities of volunteers for +holding office hours. Currently these volunteers consist of some of +the EmacsConf organizers, but we'd love to have the help of other +members of the Emacs community as well. If you are a more experienced +Emacs user and would like to help with this, please [[https://emacsconf.org/contact/][get in touch]]! + +Our first office hour this year is planned for Saturday, August 14, +from 3pm to 4pm UTC with zaeph (Leo Vivier) at the following +BigBlueButton room: https://bbb.emacsverse.org/b/ban-qye-fd1-5kw. + +,* Submitting your proposal + +Once you're ready to submit your proposal, the [[https://emacsconf.org/2021/submit/][submit]] page has the +instructions on how to submit your talk. + +We use an anonymized submission process to reduce bias and encourage +contribution. Identifying information will be removed from +submissions by a conference organizer who will not participate in +talk selection. The anonymized submissions will then be reviewed by +a selection committee. + +If your talk is approved, we'd love it if you could help us make sure +the conference runs smoothly. After we email you with the time +allotted for your talk, we'll ask you to + +- prepare a prerecording of your talk, or record it with our help if + that'd be easier for you; and +- schedule a short tech-check if you'd like to be able to answer + questions in a live session. + +Don't forget to subscribe to our main mailing list, [[https://lists.gnu.org/mailman/listinfo/emacsconf-discuss][emacsconf-discuss]], +for discussion and announcements about the EmacsConf conference. + +We look forward to your ideas and submissions! + +,* Getting involved + +If you would like to help with the conference (planning the sessions, +reviewing proposals, helping with infrastructure, making sessions more +accessible, editing video transcripts, etc.), see our [[https://emacsconf.org/2021/planning/][planning]] page +and come say hi to us at =#emacsconf= on =irc.libera.chat=. + +In addition to the [[https://lists.gnu.org/mailman/listinfo/emacsconf-discuss][emacsconf-discuss]] list, feel free to subscribe to +[[https://lists.gnu.org/mailman/listinfo/emacsconf-org][emacsconf-org]] as well, for discussions related to organizing the +conference by the EmacsConf organizers and volunteers. + +We'd really appreciate your help in making EmacsConf 2021 the best one +so far! + +,* Commitment to freedom + +We remain fully committed to freedom, and we will continue +using our infrastructure and streaming setup consisting entirely +of [[https://www.gnu.org/philosophy/free-sw.html][free software]], much like previous EmacsConf conferences. +An article describing our infrastructure and tools is underway, +and will be announced on the emacsconf-discuss list when published. + + +,* COMMENT Copyright & License + +Copyright (c) 2020 Amin Bandali, Sacha Chua, David Bremner +Copyright (c) 2021 Amin Bandali, Sacha Chua, Leo Vivier, +Sebastian Crane + +The EmacsConf 2021 Call for Proposals is part of the EmacsConf wiki, +and is dual-licensed under the terms of the Creative Commons +Attribution-ShareAlike 4.0 International Public License; and the GNU +General Public License as published by the Free Software Foundation, +either version 3 of the License, or (at your option) any later +version. + +A copy of these two licenses is available on the EmacsConf wiki, in +the [[https://emacsconf.org/COPYING.CC-BY-SA][COPYING.CC-BY-SA]] and [[https://emacsconf.org/COPYING.GPL][COPYING.GPL]] files. + +,* COMMENT How to export this file + +As of the time of writing this document (Org mode version 9.3.7), the +Org links library (=ol.el=) does not yet recognize =ircs= link types, +and will throw an error if you try to export a file containing them, +such as this file. + +To work around that, you can use something along the lines of the +Emacs Lisp code below, by either adding it to your init file, or by +putting the point in the code block and hitting =C-c C-v e= (that is, +hold Ctrl, then hit c followed by v, then release Ctrl, and hit e) to +evaluate the code, working around the issue only for the current +session. + +,#+begin_src emacs-lisp :results silent +(org-link-set-parameters + "ircs" + :export + (lambda (link description format) + "Export an ircs link. +See `org-link-parameters' for details about LINK, DESCRIPTION and +FORMAT." + (let ((desc (or description link))) + (pcase format + (`html (format "<a href=\"ircs:%s\">%s</a>" link desc)) + (`md (format "[%s](ircs:%s)" desc link)) + (_ nil))))) +,#+end_src + +#+end_src +*** Second (and final) call for proposals (closing Sep 30) :email: +:PROPERTIES: +:CUSTOM_ID: second-cfp +:END: +Sent Sept 27, 2021 to the same lists as the CFP +Included inline Markdown and attached Org version of the CFP + +**** E-mail text +:PROPERTIES: +:SUBJECT: [ANN] EmacsConf 2021 Second (and final) Call for Proposals (closing Sep 30) +:END: + +Dear fellow Emacsians, + +This is the second and final Call for Proposals for EmacsConf 2021, +open until September 30.

A few weeks ago, +we excitedly shared the EmacsConf 201 program with you. We're now +happy to share the conference schedule with you, i.e. the program +plus each talk's (approximate) scheduled time slot: + + https://emacsconf.org/2021/schedule + +All of the times listed on the schedule are in EST (UTC-5). You can +click on each talk's title to open its page for more information, +including its scheduled time in your local time (displaying local time +requires running a tiny bit of AGPLv3+-licensed free/libre JavaScript +code, included on the talk pages). For prerecorded talks, this time +is also when the talk's video will be made available on the same page. +Please note the '~' tildes near the times, indicating that they are +approximations and not meant to be taken as exact times. + +On November 27 and 28 you will be able to watch the livestreams via +https://live.emacsconf.org, which also has details on how to watch the +streams using media players that support streaming (like mpv and VLC). +Also, for Asia-Pacific folks, there will be an alternate stream by +LibreAustralia, at 11:00-17:30 UTC+11 on Sunday, November 28. Please +see the https://libreau.org/upcoming.html#emacsconf21 page on their +site for more details and how to tune into the alternate stream. + +Last but not least, please see the https://emacsconf.org/2021 page +of the EmacsConf wiki for more details on watching and participating +in the conference. + +We hope to see you all around on November 27-28 for EmacsConf 2021! + +Amin Bandali, Leo Vivier, and Sacha Chua, +On behalf of the EmacsConf 2021 organizers team +** Follow up regarding prerecorded videos :email: +:PROPERTIES: +:SUBJECT: [need answer by Friday noon EST] EmacsConf 2021: Don't have a prerec from you yet, aaah! +:CUSTOM_ID: follow-up-prerecs +:END: + +EmacsConf is in a few days and I don't think we have your prerecorded +video yet, so I'm getting miiiildly stressed about the schedule. And +you're probably stressing out about it too, so let's go figure out how +we can make this work. + +Option A: If you happen to have the prerecording or can get it done by +tomorrow, we can probably squeeze it in. Please upload it to +ftp-upload.emacsconf.org by following the instructions in +https://emacsconf.org/2021/prepare#ftp-upload , or send us a link using +your favourite file-sharing service (especially if FTP is giving you +problems). + +Option B: If you want to present live, it might be an option.

We may be able to continue streaming it on the +alternate stream. If so, people can continue watching it there if they +wish to. + +Option C: If you can't make it, that's okay. Life gets crazy +sometimes. Please let us know and we can update the wiki. If you +happen to be able to make a prerecorded video afterwards, we can add +that to the wiki, playlists, and announcements. We hope you can join +us next year. + +Since EmacsConf is *this weekend* (aaaaaaah), please let us know by +tomorrow noon EST (Friday; 9AM PST, 5PM GMT, 6PM CET) so that we can +keep the time allocated for you in the schedule. If we don't hear from +you, we'll probably reallocate the ${duration} minutes reserved for you so +that other talks can have longer Q&A.

It + is this miraculous superpower that children have to absorb + everything around them. The ability to learn language is + probably the most obvious example. So, if children can interact + with Emacs, they can start exploring it. Of course, as a text + editor, basic literacy is pretty important. I personally have + not tried teaching young children Emacs, but I believe with the + right kinds of interfaces, it could be possible. +- Q3: How to let my kids exploring Emacs?(No need to answer this. + It's simillar to Q2) + - A: Great question! Much of the early childhood Montessori work + is highly tactile. Abstract concepts are embodied in physical + objects. One example is the "binomial cube" which is a set of + blocks that demonstrates (a + b)^3. Children know nothing about + the math behind it, but by interacting with it as a tactile + puzzle, something about the math concept behind it, the + abstraction, is available to the child and their absorbent mind. + - That is to say... perhaps there are ways to bring Emacs into + the physical world for the very young. I've been fantasizing + about some kind of "physical lisp" where young children can + interact with a sort of physical programming language. I don't + have a lot of concrete ideas on how to get young children + exploring Emacs, but I do believe it is possible. + - For older, literate children, I believe simple things that give + instant feedback are a great way to encourage interaction. Being + able to do something like (set-cursor-color "orange") and see + it work at your finger tips is amazing. I believe that a well + prepared set up where M-x is easy to access and you get some + kind of completion to show you what you can do would go far. + Even ielm could be useful. Children are not nearly as afraid of + a command prompt as some grown ups are. They come to it with + much less preconceptions on how it should be used. + - I would like to think more about this, as giving children the + opportunity to experience Emacs feels critical these days, when + they may be forced into using much non-free software just do do + their school work. +- Q4: How big of an impact does the environment have on the children + that you teach? + - A: the environment is huge. giving children a prepared space + where everything is accessible to them, down at their level, the + correct size, etc, it can lead to amazing things. When I worked + with 1.5-3 year olds, I remember telling people it was like + managing a restaurant where my employees were toddlers. I could + work with a group of children to get food served into properly + sized dishes, beverages poured, ceramic plates and glass cups + set on the tables, napkins folded, and so on all finished in + time to get everyone down for lunch before we had major melt + downs.

I tend to filter out a lot of things that a + new user may pick up and stumble over. + - To re-emphasize: the elements of education are The Learner, The + Guide(s), and The Environment. Montessori focuses on the + Prepared Environment, in order that it can be the most effective + for the child's ability to become an independent, self-realized + person. +- Q5:Do you have a good reference for the Montessori principles + (actually any nice book ref)? + - A: I'd like to find a more modern resource, I'm sure they are + out there. Much of my experience was direct hands-on classroom + time. I've read much of "The Absorbent Mind" which really + lays out a lot of the observations Maria Montessori made of the + young child, 0-6 years old. The other book I've studied is + "The Secret of Childhood". I would like to stress though, a + lot of the knowledge in Montessori is very very similar to + traditional knowledge. When I was learning more about Lakota + culture and parenting, I was finding that Montessori was + expressing much of the same thing. Any resource (book, human, + whatever) that respects children as whole human beings is worth + paying attention to. Another author I've enjoyed is Aletha + Solter, who writes about parenting. +- Q6:How do you think Emacs could improve re: Montessori Principles + (if at all)? + - A: My main takeaway is that we should acknowledge the three + elements of learning: The Learner (user), The Guides + (contributors), and The (Prepared) Environment. Each user coming + to Emacs is an individual with their own mix of internal drives + (human tendencies) that compel them to learn and experience. + Everyone that is a contributor to Emacs (whether in code, on the + web, or in chat) acts as a Guide in the environment (whether + they know it or not). The Prepared Environment could be + considered how the application is set up for users. I think + there is room for a friendlier Prepared Environment, though I am + always amazed at what I can discover where the self-documenting + feature helps me out. Interactive tutorials teaching one how to + learn how to learn Emacs would be tricky, but I think some + interesting work could happen there! + - Another principle is "control of error", meaning, when you + fail at something or make a mistake, it should be obvious, and + hopefully the correction of the error should be obvious as well. + This is hard to do in a huge software environment like Emacs, + but I think there could be some work done in this regard. I'm + reminded of Racket's beginning student languages, which make + error messages more human focused and less computery is a good + example. + - I think the community could also improve as Guides. I have + certainly had many pleasant interactions with Emacs users, but + sometimes you run into things like "RTFM" or "read the + source".

By championing the opportunity for users to also be co-creators (cf.

What I found + fascinating as a non-programmer coming to Emacs was how this + approach works even in Emacs. Particularly if we are taking a + human-based approach to Emacs, it has no weakness here, because + humans can only move forwards from where they are, not where + they want to be.
