Let me give an example. -07:15.520 --> 07:17.319 -So that's it. +00:04:00.000 --> 00:04:04.000 +In the configuration in which I am now, -07:17.320 --> 07:26.039 -If you found these things interesting, just install a recent version of VEV and run the +00:04:04.000 --> 00:04:07.000 +in this file here... the old way of -07:26.040 --> 07:32.159 -tutorial either with this thing here, MetaX client client intro, or by running this exp, +00:04:07.000 --> 00:04:08.000 +generating hyperlinks to this file -07:32.160 --> 07:39.599 -or open this file here in the iv directory and follow the tutorials. +00:04:08.000 --> 00:04:10.000 +with `find-here-links' -07:39.600 --> 07:46.919 -And most things there are well documented, but the thing that I don't use much and that +00:04:10.000 --> 00:04:13.000 +will generate a temporary buffer -07:46.920 --> 07:52.559 -is mostly for demos, which is the thing that creates bidirectional hyperlinks, is not yet +00:04:13.000 --> 00:04:15.000 +like this, and then I would have to -07:52.560 --> 07:55.119 -well documented, but the rest is. +00:04:15.000 --> 00:04:18.000 +choose which one of these hyperlinks I + +00:04:18.000 --> 00:04:21.000 +find best, which one I prefer, and then + +00:04:21.000 --> 00:04:25.000 +copy it to my notes... so instead + +00:04:25.000 --> 00:04:27.000 +of choosing a hyperlink this thing here + +00:04:27.000 --> 00:04:30.000 +shows all the options. + +00:04:30.000 --> 00:04:34.000 +And in the new way, in `M-x kla' + +00:04:34.000 --> 00:04:37.000 +and friends, there's an algorithm that + +00:04:37.000 --> 00:04:39.000 +chooses the best short hyperlink by + +00:04:39.000 --> 00:04:43.000 +itself, and this algorithm is a bit hard + +00:04:43.000 --> 00:04:46.000 +to explain... let me demonstrate it here. + +00:04:46.000 --> 00:04:50.000 +Again, we have all these options here, of + +00:04:50.000 --> 00:04:51.000 +hyperlinks to this file... + +00:04:51.000 --> 00:04:56.000 +and if I type `M-x klf' + +00:04:56.000 --> 00:04:58.000 +it chooses one of them. + +00:04:58.000 --> 00:05:01.000 +And of course I can copy it to my notes, + +00:05:01.000 --> 00:05:02.000 +it's going to work, it's going to point + +00:05:02.000 --> 00:05:05.000 +to here... and so on. + +00:05:05.000 --> 00:05:08.000 +Well, the title of this presentation was + +00:05:08.000 --> 00:05:11.000 +"Bidirectional links with eev"... let me + +00:05:11.000 --> 00:05:13.000 +show what I mean by bi-directional + +00:05:13.000 --> 00:05:15.000 +hyperlinks, and how we can use this thing + +00:05:15.000 --> 00:05:17.000 +to create bidirectional hyperlinks + +00:05:17.000 --> 00:05:19.000 +very quickly. + +00:05:19.000 --> 00:05:22.000 +I will have to use a smaller font... let + +00:05:22.000 --> 00:05:25.000 +me open these two files here. This one at + +00:05:25.000 --> 00:05:27.000 +the left is a program in Haskell, and + +00:05:27.000 --> 00:05:30.000 +this one is a file with my notes on + +00:05:30.000 --> 00:05:31.000 +Haskell. + +00:05:31.000 --> 00:05:35.000 +How do I create a link from... + +00:05:35.000 --> 00:05:39.000 +to this file in Haskell + +00:05:39.000 --> 00:05:42.000 +to put it in this file here? I can put + +00:05:42.000 --> 00:05:45.000 +the cursor here, in any position + +00:05:45.000 --> 00:05:48.000 +after this anchor here, and type + +00:05:48.000 --> 00:05:49.000 +`M-x kla'... + +00:05:49.000 --> 00:05:51.000 +it copies this link here to the kill + +00:05:51.000 --> 00:05:54.000 +ring and then I can can go here and + +00:05:54.000 --> 00:05:59.000 +either insert it with C-y (yank), or + +00:05:59.000 --> 00:06:06.000 +insert it with `M-k kli', that adds a -07:55.120 --> 07:56.119 -So that's it. +00:06:06.000 --> 00:06:07.000 +comment prefix here. + +00:06:07.000 --> 00:06:11.000 +So this is a way to create a link from + +00:06:11.000 --> 00:06:15.000 +here to there in which every + +00:06:15.000 --> 00:06:18.000 +comment has to be given explicitly... + +00:06:18.000 --> 00:06:21.000 +but I also implemented a way to + +00:06:21.000 --> 00:06:23.000 +create the two links at the same time. + +00:06:23.000 --> 00:06:25.000 +I don't use it much, it's mostly for + +00:06:25.000 --> 00:06:27.000 +demos, because it's impressive, I wanted + +00:06:27.000 --> 00:06:29.000 +to show that in this presentation... + +00:06:29.000 --> 00:06:33.000 +Anyway, let me show it here. Note that + +00:06:33.000 --> 00:06:36.000 +that in this file here the point is + +00:06:36.000 --> 00:06:40.000 +here, in this file the point is here... + +00:06:40.000 --> 00:06:43.000 +My trick is going to create a link to + +00:06:43.000 --> 00:06:47.000 +this anchor and put it in this file, and + +00:06:47.000 --> 00:06:49.000 +it's going to create a link to this + +00:06:49.000 --> 00:06:52.000 +anchor and put it in this file... + +00:06:52.000 --> 00:06:57.000 +So, here it goes: `M-x kla2'... ta-da! + +00:06:57.000 --> 00:07:01.000 +it highlighted the true anchors for a + +00:07:01.000 --> 00:07:03.000 +second, and it created these things here + +00:07:03.000 --> 00:07:06.000 +and inserted them with the + +00:07:06.000 --> 00:07:09.000 +right prefixes, I mean, the right + +00:07:09.000 --> 00:07:10.000 +comment prefixes. + +00:07:10.000 --> 00:07:15.000 +And that's it! + +00:07:15.000 --> 00:07:18.000 +So... that's it. If you found this thing + +00:07:18.000 --> 00:07:22.000 +interesting just + +00:07:22.000 --> 00:07:25.000 +install a recent version of eev and run + +00:07:25.000 --> 00:07:28.000 +the tutorial, either with this thing here, + +00:07:28.000 --> 00:07:30.000 +`M-x find-kla-intro', or by running + +00:07:30.000 --> 00:07:35.000 +this sexp, or open this file here in the + +00:07:35.000 --> 00:07:37.000 +eev directory, and follow the + +00:07:37.000 --> 00:07:39.000 +tutorials... + +00:07:39.000 --> 00:07:42.000 +most things that there are well + +00:07:42.000 --> 00:07:46.000 +documented, but the thing that I don't + +00:07:46.000 --> 00:07:47.000 +use much and that is mostly for demos, + +00:07:47.000 --> 00:07:50.000 +which is the the thing that creates + +00:07:50.000 --> 00:07:52.000 +bi-directional hyperlinks, is not yet + +00:07:52.000 --> 00:07:55.000 +well documented, but the rest is. -07:56.120 --> 08:17.400 -Have fun. +00:07:55.000 --> 00:07:57.000 +So: that's it!
