| |
| − | | |
| − | * First you need a working, recent [http://www.lilypond.org LilyPond] installation (version 2.12.x) plus dependencies like GhostScript.
| |
| − | * Install the lilypond module via [[ConTeXt_Minimals#Installing_third_party_modules|ConTeXt minimals]], or get it from [[modules:t-lilypond|ConteXt garden]] or [http://github.com/fiee/ConTeXt/tree/master/t-lilypond/ github] and install it in one of your TeX trees.
| |
| − | * Include the lilypond module

| − | \usemodule[lilypond]
| |
| − | </texcode>
| |
| − | * If you want, you can change the default settings using <tt>\setuplilypond</tt>
| |
| − | * If you need lyrics with accented characters (e.g. umlauts), you '''must''' typeset in UTF-8 encoding (see [[Encodings_and_Regimes]]), because LilyPond doesn't understand anything else. And you need to use UTF-8 without BOM (byte order marker), because ConTeXt doesn't understand BOMs.
| |
| − | * Versions from May 2009 on work with LuaTeX ''only.'' Supported is only the latest beta of MkIV.

| − | == Font hints ==
| |
| − | | |
| − | LilyPond depends on the fonts that pango/fontconfig can find. But not even all of those will work, e.g. no fonts from the TeX tree (don't know why), only one face per font file etc.
| |
| − | Therefore it doesn't use ConTeXt's font setup.
| |
| − | | |
| − | If you want to know which fonts of your system LilyPond can see with which names, try
| |
| − | lilypond -dshow-available-fonts any
| |
| − | (The 3rd parameter is necessary, but can be anything.)
| |
| − | | |
| − | LilyPond's default text font is Century Schoolbook. You can use it in ConTeXt like this:
| |
| − | | |
| − | <texcode>
| |
| − | \usetypescriptfile[type-otf]

| − | == Current workarounds ==
| |
| − | | |
| − | This section lists workarounds needed in some circumstances; we surely hope to move them to [[#Older_Workarounds|'''Older Workarounds''']] as soon as possible!
| |
| − | | |
| − | === Something (LilyPond, GhostScript etc.) isn't found ===
| |
| − | | |
| − | Depending on your setup (path, installation directories, ...) you must call the lilypond app with the full path.
| |
| − | | |
| − | If <tt>pstopdf</tt> can't create PDFs (but LilyPond has made EPS files) it might be that you must set the environment variable <tt>GS_LIB</tt> for GhostScript.
| |
| − | | |
| − | === LilyPond pre-2.12 ===
| |
| − | | |
| − | The module as of 2009-05-03 works only with LilyPond 2.12 (probably also with some versions of 2.11).
| |
| − | | |
| − | For older versions of LilyPond please use an older version of the module. 2008-09 fits LilyPond 2.10
| |
| − | | |
| − | === Typesetting fret diagrams ===
| |
| − | | |
| − | Lilypond has commands to typeset fret diagrams for the guitar chords. The most important one is called <code>\fret-diagram</code> and if you want to use it, you need to play a bit with the catcode of the <code>minus</code> sign since ConTeXt is apparently confused by this. In addition, you can't type the example found in [http://lilypond.org/doc/v2.10/Documentation/user/lilypond/Overview-of-text-markup-commands#index-g_t_0040code_007bfret_002ddiagram_007d-935 the Lilypond documentation] on its own because Lilypond won't accept a score with only markup (the fret diagram) and nothing else; you have to place the markup on the page.
| |
| − | | |
| − | All in all, something like this will work:
| |
| − | | |
| − | <texcode>
| |
| − | \usemodule[lilypond]
| |
| − | \starttext
| |
| − | \catcode`\-=11
| |
| − | | |
| − | D chord:
| |
| − | \blank
| |
| − | | |
| − | \startlilypond
| |
| − | d'' ^ \markup { \fret-diagram #"s:0.75;f:1;6-x;5-x;4-o;3-2-1;2-3-3;1-2-2;" }
| |
| − | \stoplilypond
| |
| − | \catcode`\-=12
| |
| − | | |
| − | \stoptext
| |
| − | </texcode>
| |
| − | | |
| − | If you find a real solution to the <code>catcode</code> problem, please document it here, or report it to the list -- [[User:Arthur|Arthur]]
| |
| − | | |
| − | == Developer's Corner ==
| |
| − | | |
| − | For information how the integration works, please check the module code and its PDF version (both available from [[modules:t-lilypond|LilyPond on Modules]]). Unlike <tt>lilypond-book</tt> for LaTeX, the module does not use a precompiling step and thus can react to local width changes and the like, even if the LilyPond code is stored in a buffer.
| |
| − | | |
| − | Known bugs:
| |
| − | * LilyPond's EPS bounding box is sometimes a bit too small, so sometimes the content is cropped. Perhaps call eps2eps or the like to fix that?
| |
| − | | |
| − | Things that have not been implemented yet include:
| |
| − | * work with existing PDFs on systems where LilyPond isn't installed.
| |
| − | * make lilypond call back on ConTeXt for included TeX (cf. [http://lsr.dsi.unimi.it/LSR/Item?id=107])
| |
| − | * get information from LilyPond about the baseline, for run-in music fragments
| |
| − | * tell LilyPond how much space is left on the first page
| |
| − | * check and probably work on proper multi-page music
| |
| − | * it's not possible to set variables in LilyPond
| |
| − | * lots of features
| |
| − | | |
| − | To remember:
| |
| − | * see [http://lilypond.org/doc/v2.12/Documentation/ LilyPond Docs]!

| |
| − | | |
| − | === Fonts with ConTeXt MkII ===
| |
| − | | |
| − | For the latest versions of the module work with ConTeXt MkIV (LuaTeX) exclusively, so we moved this to "Older":

| |
| − | | |
| − | === LilyPond is not found ===
| |
| − | | |
| − | Calling lilypond from command line in Windows fails.
| |
| − | | |
| − | You have two options:
| |
| − | * modify the module, so that lilypond is called with the whole path (<code>C:/prog/lilypond/usr/bin/lilypond</code> for example instead of <code>lilypond</code> alone).
| |
| − | * place a <code>lilypond.bat</code> somewhere in your search path, calling
| |
| − | c:/prog/lilypond/usr/bin/lilypond %1 %2 %3 %4 %5 %6 %7 %8 %9
| |
| − | | |
| − | Calling lilypond from ConTeXt via shell exit (write18) in MacOS X also fails, even if the shell's path is right. (Seems more like write18 wouldn't use the environment.) Modify the module (try <tt>which lilypond</tt> to get its path).
| |
| − | | |
| − | LilyPond 2.7.26 comes without a command line "version", at least in the MacOS X edition, i.e. the <tt>lilypond.sh</tt> script is missing.
| |

LilyPond is a great music engraver, and you can include LilyPond in ConTeXt source using the filter module with some setup.
Simple Filter Setup
This works with ConTeXt MkII and MkIV, but takes only the first page of multi-pages scores, and you must create the folder "lilytemp" manually:
\def\readPDFfile#1{\externalfigure[#1]}
\usemodule[filter]
\defineexternalfilter[lilypond]
[continue=yes,
readcommand=\readPDFfile,
directory=lilytemp/,
output={\externalfilterbasefile.pdf},
filtercommand={lilypond -dbackend=eps -dno-gs-load-fonts -dinclude-eps-fonts -ddelete-intermediate-files -o"lilytemp/\externalfilterbasefile" "\externalfilterinputfile"}]
Multi Page Filter Setup
This uses Lua and therefore only works with ConTeXt MkIV. It includes all pages of multi-page scores.
It doesn’t look into the complete (multi-page) PDF, but reads a "-system.count" auxiliary file written by LilyPond that contains the number of systems (pages) and includes the single-system PDFs.
\def\ParseLilypondFile#1
{\ctxlua{thirddata.parselilypondfile("#1")}}
\startluacode
thirddata = thirddata or {}
-- create temp folder if missing
if not lfs.isdir('lilytemp') then
lfs.mkdir('lilytemp')
end
function thirddata.parselilypondfile(name)
-- include all systems (pages)
-- name is like lilytemp/mainfile-temp-lilypond-21.pdf
logs.report("LILYPOND name='" .. name .. "'")
syco = 0
for ts in io.lines(string.gsub(name, '
syco = ts*1
end
for nr = 1, syco do
logs.report("LILYPOND including system no." .. nr)
context("\\externalfigure[" .. string.gsub(name, '
end
end
\stopluacode
\usemodule[filter]
\defineexternalfilter[lilypond]
[continue=yes,
readcommand=\ParseLilypondFile,
directory=lilytemp/,
output={\externalfilterbasefile.pdf},
filtercommand={lilypond -dbackend=eps -dinclude-eps-fonts -dno-gs-load-fonts -o"lilytemp/\externalfilterbasefile" "\externalfilterinputfile"}]
LilyPond Settings
Collect your LilyPond settings in a .ly file, put it in your lilytemp directory and include it from within your lilypond block like this:
\startlilypond
\include "mysettings.ly"
...
\stoplilypond
Named Buffers
Normally, your LilyPond snippets just get a running number. If you re-order your scores, each one gets re-rendered.
You might want to add [name=\currentcomponent] (or name=mymusic) to \startlilypond to avoid unnecessary re-rendering.
