I'm going to export this document + +00:05:04.320 --> 00:05:05.120 +to a PDF file. + +00:05:05.120 --> 00:05:08.240 +In this case, the + +00:05:08.240 --> 00:05:10.639 +:file header argument is required, so you + +00:05:10.639 --> 00:05:11.919 +have to provide one + +00:05:11.919 --> 00:05:15.600 +and include the file name. + +00:05:15.600 --> 00:05:17.919 +Again, you can run the code and view + +00:05:17.919 --> 00:05:22.160 +the results. + +00:05:22.160 --> 00:05:25.840 +Here it is. So now let's + +00:05:25.840 --> 00:05:33.680 +export this to a PDF file. + +00:05:33.680 --> 00:05:39.680 +And here it is, what it generates. + +00:05:39.680 --> 00:05:41.440 +Now I'm going to show you the workflow I + +00:05:41.440 --> 00:05:44.000 +used to produce music books in Emacs, + +00:05:44.000 --> 00:05:46.160 +combining Lilypond and LaTeX for a + +00:05:46.160 --> 00:05:48.000 +perfect marriage. + +00:05:48.000 --> 00:05:50.160 +I begin by sketching the first draft of the + +00:05:50.160 --> 00:05:53.039 +manuscript using pencil and paper. + +00:05:53.039 --> 00:05:55.039 +Then I move to Emacs to input the notes + +00:05:55.039 --> 00:05:57.440 +in a git repository. + +00:05:57.440 --> 00:06:00.080 +This is a typical source file. It begins + +00:06:00.080 --> 00:06:01.360 +with a stylesheet + +00:06:01.360 --> 00:06:03.199 +where I set variables and layout + +00:06:03.199 --> 00:06:05.440 +settings, although in general, there's no + +00:06:05.440 --> 00:06:07.039 +need for tweaking the layout + +00:06:07.039 --> 00:06:09.280 +unless you have specific requirements to + +00:06:09.280 --> 00:06:11.199 +do so. + +00:06:11.199 --> 00:06:13.360 +The easiest way to compile the file from + +00:06:13.360 --> 00:06:15.520 +Emacs is by pressing C-c C-l, + +00:06:15.520 --> 00:06:19.280 +so let's do this now, + +00:06:19.280 --> 00:06:21.199 +and the compilation buffer will tell you + +00:06:21.199 --> 00:06:23.759 +if there were any errors in the file. + +00:06:23.759 --> 00:06:26.000 +Now to automate the process of compiling + +00:06:26.000 --> 00:06:28.560 +several files and building the PDF, + +00:06:28.560 --> 00:06:31.280 +I use GNU Make, so all I have to do is + +00:06:31.280 --> 00:06:32.560 +open the shell + +00:06:32.560 --> 00:06:36.000 +and run the make command. Don't worry, + +00:06:36.000 --> 00:06:37.840 +I'll provide a link to the source code + +00:06:37.840 --> 00:06:41.600 +on the last slide. + +00:06:41.600 --> 00:06:43.600 +As I moved forward with the project, I + +00:06:43.600 --> 00:06:46.000 +found at least two things missing. + +00:06:46.000 --> 00:06:48.720 +One, I had no access to a metronome, + +00:06:48.720 --> 00:06:50.479 +at least not from the editor, + +00:06:50.479 --> 00:06:52.960 +so I built one for casual use and made + +00:06:52.960 --> 00:06:55.919 +it available in the MELPA repository. + +00:06:55.919 --> 00:06:59.039 +I also missed bar numbers in the source file. + +00:06:59.039 --> 00:07:00.880 +This is useful when going back and forth + +00:07:00.880 --> 00:07:03.199 +between input and output files without + +00:07:03.199 --> 00:07:04.479 +getting lost. + +00:07:04.479 --> 00:07:06.720 +So I wrote a command for toggling bar + +00:07:06.720 --> 00:07:10.000 +numbers, which I hope you can see on the left. + +00:07:10.000 --> 00:07:12.080 +Also, some expressions are difficult or + +00:07:12.080 --> 00:07:14.160 +slow to write on the keyboard-- + +00:07:14.160 --> 00:07:17.039 +accents and tuplets, for example--so I use + +00:07:17.039 --> 00:07:20.160 +template expansion extensively for this purpose, + +00:07:20.160 --> 00:07:23.440 +mainly ya-snippet. + +00:07:23.440 --> 00:07:25.680 +So what do I think? Well, I think + +00:07:25.680 --> 00:07:28.080 +Lilypond can be a sharp paradigm shift + +00:07:28.080 --> 00:07:31.039 +for people used to GUI alternatives, but + +00:07:31.039 --> 00:07:32.720 +the results are impressive. + +00:07:32.720 --> 00:07:34.639 +You don't have to dive too deeply to + +00:07:34.639 --> 00:07:36.960 +start using Lilypond. + +00:07:36.960 --> 00:07:38.880 +Likewise, the ability to extend the + +00:07:38.880 --> 00:07:40.720 +software, I think, is especially appealing + +00:07:40.720 --> 00:07:42.400 +for music professionals, + +00:07:42.400 --> 00:07:45.199 +enthusiasts, composers, and the academic + +00:07:45.199 --> 00:07:46.560 +community: + +00:07:46.560 --> 00:07:48.400 +for example, allowing users to create + +00:07:48.400 --> 00:07:50.800 +alternative notation systems required in + +00:07:50.800 --> 00:07:53.120 +non-Western music traditions + +00:07:53.120 --> 00:07:56.160 +and other non-conventional requirements. + +00:07:56.160 --> 00:07:58.400 +Also, Lilypond and Emacs both have + +00:07:58.400 --> 00:08:00.720 +extensive and well-written manuals + +00:08:00.720 --> 00:08:04.639 +and active communities of users. + +00:08:04.639 --> 00:08:06.400 +But if you're still not sure where to + +00:08:06.400 --> 00:08:09.599 +start and when to wedge your feet in the deep + +00:08:09.599 --> 00:08:12.160 +but warm pond of lilies, Lilypond, and + +00:08:12.160 --> 00:08:13.680 +Lilypond users, + +00:08:13.680 --> 00:08:15.680 +I invite you to contribute to my + +00:08:15.680 --> 00:08:16.960 +Lilypond projects, + +00:08:16.960 --> 00:08:18.800 +which you can do so from the links on + +00:08:18.800 --> 00:08:20.720 +the screen. + +00:08:20.720 --> 00:08:22.800 +So, thank you all. I look forward to your + +00:08:22.800 --> 00:08:24.639 +comments, and I hope you enjoy the rest + +00:08:24.639 --> 00:08:27.840 +of the conference. |
