-00:07.200 --> 00:00:08.400 -blocks - -00:08.400 --> 00:00:10.320 -let's start by demo - -00:10.320 --> 00:00:12.559 -this is a file in lua that defines these - -00:12.559 --> 00:00:14.160 -two functions here - -00:14.160 --> 00:00:16.720 -and with it if we type f8 several times - -00:16.720 --> 00:00:18.000 -here - -00:18.000 --> 00:00:20.880 -the f8s create a lower apple here and - -00:20.880 --> 00:00:24.400 -then they send these lines to the rebel - -00:24.400 --> 00:00:27.039 -where this line here loads this file - -00:27.039 --> 00:00:29.679 -into the repo and these other lines here - -00:29.679 --> 00:00:33.200 -are tests for these lines - -00:33.200 --> 00:00:35.120 -there's a lot of information here so let - -00:35.120 --> 00:00:40.480 -me organize them in a more visual way - -00:40.480 --> 00:00:42.960 -this is our file in lua - -00:42.960 --> 00:00:45.760 -lua sees this thing as a as a multi-line - -00:45.760 --> 00:00:47.760 -comment but we are going to see it as a - -00:47.760 --> 00:00:51.920 -test block and eev mode is active and so - -00:51.920 --> 00:00:54.480 -f8 does the right thing - -00:54.480 --> 00:00:57.360 -uh these three lines here set up the - -00:57.360 --> 00:01:00.079 -target buffer running a lower apple you - -01:00.079 --> 00:01:03.520 -can see the the prompt of the rebel here - -01:03.520 --> 00:01:05.360 -and these lines here are sent to the - -01:05.360 --> 00:01:07.200 -rebel - -01:07.200 --> 00:01:09.680 -and when we type f8 on the line that - -01:09.680 --> 00:01:10.720 -starts - -01:10.720 --> 00:01:13.600 -with the red star like these lines here - -01:13.600 --> 00:01:15.759 -what if it does is that it sends the - -01:15.759 --> 00:01:18.240 -rest of the line sorry it - -01:18.240 --> 00:01:21.119 -executes the rest of the line as lisp - -01:21.119 --> 00:01:23.920 -so it executes the three effects here - -01:23.920 --> 00:01:26.240 -executes these lines as lisp and they - -01:26.240 --> 00:01:29.520 -set up the target buffer here - -01:29.520 --> 00:01:31.759 -and when we type f8 on the line that - -01:31.759 --> 00:01:34.159 -does not start with the red star - -01:34.159 --> 00:01:36.640 -the f8 sends the line to the target - -01:36.640 --> 00:01:38.799 -buffer and moves down - -01:38.799 --> 00:01:41.040 -and this line loads this file under - -01:41.040 --> 00:01:45.200 -apple and these lines are tests - -01:45.200 --> 00:01:47.520 -so we just saw how to use an existing - -01:47.520 --> 00:01:50.000 -test block let's now see how to create a - -01:50.000 --> 00:01:52.640 -new test block we just have to run this - -01:52.640 --> 00:01:55.680 -meta x e insert test block - -01:55.680 --> 00:01:58.079 -or meta x euat - -01:58.079 --> 00:02:01.439 -and the result depends on the major mode - -02:01.439 --> 00:02:03.920 -uh let's see let's understand that that - -02:03.920 --> 00:02:06.079 -by looking at the source code - -02:06.079 --> 00:02:08.720 -eeit is an alias to this function here - -02:08.720 --> 00:02:10.640 -and this function is just five lines of - -02:10.640 --> 00:02:12.800 -code plus a dot string - -02:12.800 --> 00:02:14.560 -and the dot string explains that if the - -02:14.560 --> 00:02:16.480 -major mode is full mode then this - -02:16.480 --> 00:02:18.800 -function tries to call - -02:18.800 --> 00:02:21.360 -a function called e insert test plot - -02:21.360 --> 00:02:24.800 -test full mode if that function exists - -02:24.800 --> 00:02:27.280 -and that if that function does not exist - -02:27.280 --> 00:02:29.680 -then it yields an error - -02:29.680 --> 00:02:32.080 -and here's an example of one such - -02:32.080 --> 00:02:34.239 -function that's a function that - -02:34.239 --> 00:02:37.280 -inserts a test block in haskell mode - -02:37.280 --> 00:02:40.319 -and here we can see two functions like - -02:40.319 --> 00:02:42.480 -this one for haskell mode and one for - -02:42.480 --> 00:02:46.080 -javascript mode - -02:46.080 --> 00:02:48.560 -uh these functions look quite similar - -02:48.560 --> 00:02:49.440 -but - -02:49.440 --> 00:02:52.720 -their effects look quite different - -02:52.720 --> 00:02:55.760 -to make this comparison here i started - -02:55.760 --> 00:02:57.280 -by writing - -02:57.280 --> 00:02:59.680 -by creating seven files each one in a - -02:59.680 --> 00:03:01.120 -different language - -03:01.120 --> 00:03:03.040 -and initially each one of these files - -03:03.040 --> 00:03:04.959 -only had a comment with the name of the - -03:04.959 --> 00:03:08.239 -language so c haskell javascript org - -03:08.239 --> 00:03:10.560 -mode etc - -03:10.560 --> 00:03:13.040 -and in each one of these files i typed - -03:13.040 --> 00:03:16.959 -meta x eeit to insert the test block - -03:16.959 --> 00:03:18.800 -so here we can see that these test - -03:18.800 --> 00:03:20.319 -blocks are different - -03:20.319 --> 00:03:22.080 -for example the syntax for multi-line - -03:22.080 --> 00:03:24.000 -comments is different depending on the - -03:24.000 --> 00:03:25.200 -language - -03:25.200 --> 00:03:27.760 -uh this block here that selects which - -03:27.760 --> 00:03:30.319 -rebel to run is also different - -03:30.319 --> 00:03:33.200 -this line here that shows how that - -03:33.200 --> 00:03:34.879 -tells the repo to - -03:34.879 --> 00:03:37.680 -load the current file is also different - -03:37.680 --> 00:03:39.680 -depending on the language - -03:39.680 --> 00:03:41.840 -in some cases i had to improvise a bit - -03:41.840 --> 00:03:43.360 -for example - -03:43.360 --> 00:03:46.400 -uh to implement test blocks in shell - -03:46.400 --> 00:03:48.560 -mode i had to use this - -03:48.560 --> 00:03:52.560 -this with syntax using a rear document - -03:52.560 --> 00:03:55.280 -in tcl i also had to improvise a bit and - -03:55.280 --> 00:03:57.840 -in some cases i had to improvise a lot - -03:57.840 --> 00:04:01.120 -for example in org mode there isn't an - -04:01.120 --> 00:04:03.360 -obvious rebel to run and there isn't an - -04:03.360 --> 00:04:05.280 -obvious way to load the - -04:05.280 --> 00:04:08.080 -the current org file into the repo so - -04:08.080 --> 00:04:11.680 -the default action of meta x eeit - -04:11.680 --> 00:04:14.400 -in log mode is just to insert this thing - -04:14.400 --> 00:04:15.439 -here - -04:15.439 --> 00:04:17.519 -that we can use to run a - -04:17.519 --> 00:04:22.320 -shell in a rebel - -04:22.320 --> 00:04:23.199 -so - -04:23.199 --> 00:04:25.680 -these functions are quite similar and in - -04:25.680 --> 00:04:27.440 -the beginning i was writing all of them - -04:27.440 --> 00:04:29.680 -by hand but then i got bored and i wrote - -04:29.680 --> 00:04:32.320 -a function to help you write functions - -04:32.320 --> 00:04:33.840 -like that - -04:33.840 --> 00:04:35.759 -this function is called - -04:35.759 --> 00:04:38.080 -find e-uit-links and it creates a - -04:38.080 --> 00:04:39.919 -temporary buffer - -04:39.919 --> 00:04:41.680 -and the contents of this temporary - -04:41.680 --> 00:04:43.440 -buffer depends on the major mode for - -04:43.440 --> 00:04:45.680 -example if the current mode is python - -04:45.680 --> 00:04:48.880 -mode then running this function here - -04:48.880 --> 00:04:51.840 -creates a temporary buffer that lets me - -04:51.840 --> 00:04:53.840 -write the support for - -04:53.840 --> 00:04:56.880 -test blocks into python mode or rewrite - -04:56.880 --> 00:04:59.040 -the function that supports test blocks - -04:59.040 --> 00:05:00.880 -and python mode - -05:00.880 --> 00:05:03.600 -so if i'm in python mode and i run this - -05:03.600 --> 00:05:06.639 -i get a temporary buffer like this - -05:06.639 --> 00:05:08.800 -in which this thing is my template for - -05:08.800 --> 00:05:11.120 -the function usually this thing is - -05:11.120 --> 00:05:13.039 -totally wrong i have to rewrite to this - -05:13.039 --> 00:05:13.919 -string - -05:13.919 --> 00:05:16.400 -but the rest is right you can see python - -05:16.400 --> 00:05:18.720 -mode here in the name of the function so - -05:18.720 --> 00:05:21.360 -we have to edit this and save that to - -05:21.360 --> 00:05:22.840 -our home - -05:22.840 --> 00:05:25.520 -slash.mx and by the way these things - -05:25.520 --> 00:05:28.880 -here hyperlinks to many different things - -05:28.880 --> 00:05:31.600 -this elias piper link here - -05:31.600 --> 00:05:34.160 -points to the source code to the section - -05:34.160 --> 00:05:35.280 -in which - -05:35.280 --> 00:05:36.400 -these - -05:36.400 --> 00:05:38.400 -functions are defined - -05:38.400 --> 00:05:40.320 -so you can see this here the function - -05:40.320 --> 00:05:41.759 -that supports c - -05:41.759 --> 00:05:43.440 -the function for haskell the function - -05:43.440 --> 00:05:46.400 -for javascript etc - -05:46.400 --> 00:05:49.440 -and that's it this is a five-minute talk - -05:49.440 --> 00:05:50.960 -so i can't say much - -05:50.960 --> 00:05:52.639 -if you want more information or if you - -05:52.639 --> 00:05:55.120 -want to see real world examples how i - -05:55.120 --> 00:05:58.000 -use test blocks etc etc see this page - -05:58.000 --> 00:06:00.479 -here and i do not have time to explain - -06:00.479 --> 00:06:02.560 -this by the way here - -06:02.560 --> 06:06.080 -so that's it thanks |
