[[!template text="""When I'm talking about Lisp here,""" start="00:00:21.400" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""I'm talking about the idea of Lisp,""" start="00:00:22.880" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""so the family of languages that are Lisp.""" start="00:00:27.560" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""But given that there's no formal specification of Lisp,""" start="00:00:30.120" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""so the opinion might vary. I will expect that Lisp,""" start="00:00:34.720" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""most of the Lisp have these kind of features.""" start="00:00:40.600" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""The first one is homoiconic:""" start="00:00:44.440" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""the code is data, basically.""" start="00:00:46.240" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""They also have a REPL: read-eval-print loop.""" start="00:00:49.800" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""That is very powerful and can help in development.""" start="00:00:52.560" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Also, I think a good Lisp""" start="00:00:57.760" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""should have a powerful macro system.""" start="00:01:00.360" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""I'm good with compile-time macros,""" start="00:01:03.320" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""but read-time is also interesting.""" start="00:01:05.760" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""There's a lot of Lisp that you can choose.""" start="00:01:07.600" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""There's the main three ones, of course,""" start="00:01:10.280" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""with Scheme, Common Lisp, and Clojure.""" start="00:01:12.000" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Scheme by Guile, Common Lisp by Common Lisp,""" start="00:01:13.840" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""and Clojure by Clojure or ClojureScript.""" start="00:01:19.675" video="mainVideo-emacsen" id="subtitle"]]

[[!template new="1" text="""Why Emacs Lisp was chosen""" start="00:01:26.640" video="mainVideo-emacsen" id="subtitle"]]

[[!template text="""So let's talk about Emacs Lisp.""" start="00:01:26.640" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""I didn't mention Emacs Lisp.""" start="00:01:28.080" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""I'm going to talk about why Emacs Lisp""" start="00:01:29.680" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""was chosen for an Emacs editor.""" start="00:01:32.520" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""We're going to explore this kind of design of the Emacs.""" start="00:01:35.600" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""And Emacs Lisp is the main language of it. Why?""" start="00:01:39.160" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Given that there were a few alternatives at the time,""" start="00:01:42.280" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""why Emacs Lisp was chosen?""" start="00:01:44.960" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""So RMS, Richard Stallman, needed a Lisp,""" start="00:01:48.160" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""and there wasn't one available at the time.""" start="00:01:51.920" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Keep in mind, this was the early 80s.""" start="00:01:54.280" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Stallman was writing at that point the GCC, I think,""" start="00:01:57.040" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""and he was writing the core components""" start="00:02:03.241" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""of what is going to become GNU.""" start="00:02:07.975" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""He needed an editor. He wanted Lisp. He wanted Emacs.""" start="00:02:10.441" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""So he wrote Emacs Lisp. So at that time,""" start="00:02:15.500" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""the functionality was more important than &quot;perfection.&quot;""" start="00:02:20.281" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""What I mean [by] &quot;perfection&quot; is: we programmers""" start="00:02:24.600" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""sometimes like to make everything good""" start="00:02:26.640" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""or very, very good when sometimes, indeed,""" start="00:02:33.360" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""it's more important that it works""" start="00:02:36.480" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""to do the task that it should.""" start="00:02:39.120" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""And it's not a bad language.""" start="00:02:42.920" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""It's not that bad. At that time, it was mostly nice.""" start="00:02:44.200" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Today, it's good enough, I think.""" start="00:02:50.240" video="mainVideo-emacsen" id="subtitle"]]

[[!template new="1" text="""Other "Emacsen"""" start="00:02:54.841" video="mainVideo-emacsen" id="subtitle"]]

[[!template text="""He wasn't the first one, the GNU Emacs,""" start="00:02:54.841" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""nor the only one, of course.""" start="00:02:59.461" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""There were others: Hemlock, Zmacs, and Climacs...""" start="00:03:02.541" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Two of them, I think, were written in Common Lisp,""" start="00:03:06.440" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""and Zmacs was written in a Lisp from a Lisp machine,""" start="00:03:08.981" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""so it was an implementation of Emacs.""" start="00:03:14.480" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Not GNU Emacs, but the original idea""" start="00:03:16.640" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""of Emacs for a Lisp machine.""" start="00:03:19.040" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""So Hemlock was written in Common Lisp,""" start="00:03:22.080" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""but it's no longer used and no longer developed,""" start="00:03:23.760" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""as far as I know. And Climacs, it was developed,""" start="00:03:26.080" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""but it was abandoned, I think.""" start="00:03:29.000" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""So three of them failed for different reasons.""" start="00:03:31.520" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Zmacs was because of the Lisp machine market crash,""" start="00:03:33.640" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""and yeah, it also failed.""" start="00:03:37.880" video="mainVideo-emacsen" id="subtitle"]]

[[!template new="1" text="""Why not Common Lisp?""" start="00:03:38.581" video="mainVideo-emacsen" id="subtitle"]]

[[!template text="""So Emacs got alone. And in the 90s, interesting to explore,""" start="00:03:38.581" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""some people suggest that why""" start="00:03:44.040" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""now that we have a standard Lisp, right,""" start="00:03:46.480" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""because Common Lisp was standardized in '94,""" start="00:03:49.680" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""why don't we change Emacs Lisp to Common Lisp?""" start="00:03:52.560" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""These are the other reasons I think are important,""" start="00:03:56.720" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""because that's why Stallman didn't choose Common Lisp.""" start="00:03:59.000" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""But I think the main one""" start="00:04:01.160" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""that I didn't write here""" start="00:04:02.040" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""is that Stallman wasn't a big fan of Common Lisp,""" start="00:04:03.760" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""and he was at the time the main developer""" start="00:04:09.040" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""and maintainer, of course, for Emacs.""" start="00:04:12.680" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""So he chose not to move to Common Lisp.""" start="00:04:14.041" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""But other reasons may be why...""" start="00:04:16.440" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Because he had a late and painful standardization.""" start="00:04:18.480" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Keep in mind, the first book that Guy Steele wrote""" start="00:04:22.920" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""was in 1984. The standardization finished in 19--""" start="00:04:28.040" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""sorry, in 1984 was the first book""" start="00:04:32.240" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""and the standardization finished in 1994.""" start="00:04:38.280" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""So, like, 10 years of difference from one to the other.""" start="00:04:44.421" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""10 years of a lot of talk, a lot of money,""" start="00:04:48.120" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""and a lot of pain probably.""" start="00:04:51.880" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""The Lisp usage declined in the 90s""" start="00:04:56.400" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""due to the AI winter.""" start="00:04:59.200" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""We all know about the Lisp machine market crash.""" start="00:05:00.960" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""And the failure of commercial Lisp machine was""" start="00:05:03.360" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""inevitable at that point.""" start="00:05:08.840" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""So all the potential Emacs friends died.""" start="00:05:12.240" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""And also a lot of Emacs Lisp was already available.""" start="00:05:17.161" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Emacs was already an amateur utility.""" start="00:05:21.280" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Unix won the war of the operating system, as we know,""" start="00:05:24.560" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""and Emacs Lisp was available in Unix,""" start="00:05:29.960" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""or in GNU/Linux, as we know,""" start="00:05:33.840" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""which is the most successful implementation of Unix.""" start="00:05:36.920" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Sorry, BSD. Okay.""" start="00:05:40.480" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""So Emacs won by being the &quot;better&quot; alternative.""" start="00:05:44.208" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""I'm quoting &quot;better&quot; here because""" start="00:05:48.400" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""I think Emacs does have a better design""" start="00:05:50.000" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""and, well, it was the one that survived, right?""" start="00:05:53.700" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""Which is the more important thing for a software or,""" start="00:05:56.960" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""you know... So Emacs won by being free,""" start="00:06:00.040" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""also in price, which I think the Lisp machine wasn't.""" start="00:06:05.160" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""So that was also very good. It was included.""" start="00:06:08.400" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""It had, and it still has, of course,""" start="00:06:11.520" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""a nice collection of packages""" start="00:06:14.560" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""that improve the standard functionality.""" start="00:06:15.880" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""It was easy to extend because of the nature of Lisp.""" start="00:06:20.680" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""And it has a very good integration with GNU/Linux,""" start="00:06:23.480" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""of course. It was created to write it.""" start="00:06:26.040" video="mainVideo-emacsen" id="subtitle"]]
[[!template text="""It makes sense that it's very good""" start="00:06:29.400" video="mainVideo-emacsen" id="subtitle"]]
