[[!template text="""dropped in and replaced.""" start="00:01:22.087" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""So over the course of the talk,""" start="00:01:26.400" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""hopefully I'll come back to that thesis.""" start="00:01:26.421" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""There's some cruft, I think, in my local.""" start="00:01:49.200" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""All right, so this config block at the top...""" start="00:01:53.160" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""between the code and the documentation.""" start="00:01:58.120" video="mainVideo-orgvm" id="subtitle"]]
[[!template new="1" text="""So the first thing I want to point out""" start="00:02:01.880" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""is that this is written in Node.js,""" start="00:02:04.080" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""You might well come up with a different version of this""" start="00:02:25.760" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""that's even cooler.""" start="00:02:28.760" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""are full of cross links to each other.""" start="00:03:01.421" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""particularly to HTML.""" start="00:03:10.080" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""But it made sense for me to include Markdown, PDF,""" start="00:03:12.280" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""or whatever format I want.""" start="00:03:17.280" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""Because many times, I'm going to look at that file""" start="00:03:18.880" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""and then pop it into an email or upload it somewhere.""" start="00:03:22.760" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""And then finally, it should be, therefore,""" start="00:03:29.480" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""pretty easy to download the document""" start="00:03:33.240" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""rather than view it, once I'm done.""" start="00:03:33.754" video="mainVideo-orgvm" id="subtitle"]]
[[!template new="1" text="""So let's just run a quick demo.""" start="00:03:38.320" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""You'll see I'm still a Windows user.""" start="00:03:42.200" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""Yeah, I'm working on it.""" start="00:03:44.760" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""So all right, first thing that we're going to do""" start="00:03:45.960" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""is fire up the program.""" start="00:03:52.320" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""Actually, for simplicity, let's just""" start="00:03:53.320" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""admit we live in a DOS world.""" start="00:04:00.200" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""to get the application running.""" start="00:04:19.760" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""So with that done, then, I can run out to my localhost.""" start="00:04:22.680" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""And we'll just start by plugging in the name of an Org file.""" start="00:04:25.960" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""So I've got a little Org file that I prepared""" start="00:04:37.560" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""You can see, nothing up my sleeve.""" start="00:05:10.280" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""This is a very basic Org file""" start="00:05:11.960" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""Images work.""" start="00:05:16.560" video="mainVideo-orgvm" id="subtitle"]]

[[!template new="1" text="""All right, let's come back to the documentation.""" start="00:05:29.760" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""I pretty well covered this, I think.""" start="00:05:33.760" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""But you'll need a relatively recent version of Emacs.""" start="00:05:36.680" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""I haven't taken any pains to make this backward compatible.""" start="00:05:39.720" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""To be fair, I haven't tested it extensively.""" start="00:05:43.640" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""It may well work on Emacs 26 or older versions.""" start="00:05:46.000" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""as well as recent builds of 29.""" start="00:05:55.120" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""There's some quick start instructions here,""" start="00:05:57.080" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""which I'm going to take as read.""" start="00:06:02.560" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""You probably saw the key element of this,""" start="00:06:03.900" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""You do-- I will call out Yale.""" start="00:06:11.920" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""If you're trying to play with this yourself,""" start="00:06:13.520" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""don't forget to run the npm install command.""" start="00:06:15.320" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""That'll bring in express.js,""" start="00:06:20.080" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""To use this, we're simply giving the document name""" start="00:06:33.480" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""without the .org extension in whatever file path--""" start="00:06:35.920" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""I also want to call attention to the fact""" start="00:06:50.800" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""that nothing in this program protects you""" start="00:06:52.960" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""from damaging yourself.""" start="00:06:55.880" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""This isn't meant as a production capability.""" start="00:06:57.240" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""This is something that's used to publish""" start="00:07:00.560" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""your own note files""" start="00:07:00.587" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""That's something I'll definitely look at adding,""" start="00:07:06.520" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""but I want people to be careful of it""" start="00:07:08.680" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""while this is in an alpha state.""" start="00:07:12.240" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""So the default response is HTML, and we saw that here.""" start="00:07:14.720" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""But we also can modify the response format.""" start="00:07:22.960" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""We're currently supporting HTML, Markdown, and PDF.""" start="00:07:26.240" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""And that's really enough to select a different format.""" start="00:07:29.800" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""That's really nothing more than adding type. Okay.""" start="00:07:34.280" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""Not sure what's going on there.""" start="00:07:48.040" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""But this, fortunately, this error message""" start="00:08:03.920" video="mainVideo-orgvm" id="subtitle"]]

[[!template text="""that I'd really like to focus on,""" start="00:08:08.840" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""hopefully bringing me back to that thesis.""" start="00:08:10.240" video="mainVideo-orgvm" id="subtitle"]]
[[!template new="1" text="""So as we start to look at code, what we're looking for""" start="00:08:13.520" video="mainVideo-orgvm" id="subtitle"]]
[[!template text="""is really this Emacs Lisp that's getting generated here.""" start="00:08:17.760" video="mainVideo-orgvm" id="subtitle"]]
