* First you need a working, recent [http://www.lilypond.org LilyPond] installation (version 2.10+) plus dependencies like GhostScript.
* Include the lilypond module
* If you want, you can change the default settings using <cmd>setuplilypond</cmd>
* 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.
* The module should work with LuaTeX, thanks to Mojca Miklavec.
== Snippets ==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.
There are some notes \lilyponddef\LILYTEMP{lilytemp} % name of folder for LilyPond/buffer files \def\ParseLilypondFile#1% #1 is the name of the output file { \relativectxlua{bes a c bthirddata.parselilypondfile("#1")}} \startluacode thirddata = thirddata or {} embedded in this line -- 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 .. "'") local scname = string.gsub(name, '%.pdf$', '-systems.count') local syco = tonumber(io.loaddata(scname)) or 0 for nr = 1, syco do logs.report("LILYPOND","including system no." .. nr) context("\\externalfigure[" .. string.gsub(name, '%.pdf$', '-' .. nr) ..

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.== Automatical width adaption ==
LilyPond's default text font is Century Schoolbook -- this goes after "create temp folder" io.savedata("\LILYTEMP/texsettings.ly", "\\paper { line-width = " .. You can use it in ConTeXt like this: string.gsub(number.todimen(tex.dimen.textwidth),"pt","\\pt") .. " } \n")
== Current workarounds ==You must comment/delete the "line-width" setting in mysettings.ly, otherwise it doesn’t work.
This section lists workarounds needed in some circumstances; we surely hope to move them to [[#Older_Workarounds|'''Older Workarounds''']] as soon as possible!== Example ==
=== LilyPond 2.11 ===Here's an example of placing score snippets in the body of the text, with fonts in the score & body matching:
Look for \def\ParseLilypondFile#1% #1 is the lilypond call in <tt>m-lilypondname of the output file {\ctxlua{thirddata.tex</tt> and replace parselilypondfile("-b eps#1" with "-dbackend=eps". Perhaps you must also call the lilypond app with the full path.)}}
Lilypond has commands to typeset fret diagrams for the guitar chords. The most important one is called <code>\fret --diagram</code> and create temp folder if missing 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 thisnot lfs. In addition, you can't type the example found in [http://lilypond.org/doc/v2isdir("\LILYTEMP") then lfs.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 mkdir(the fret diagram"\LILYTEMP") and nothing else; you have to place the markup on the page. end
All in function thirddata.parselilypondfile(name) -- include allsystems (pages) -- name is like \LILYTEMP/mainfile-temp-lilypond-21.pdf logs.report("LILYPOND","name='" .. name .. "'") local scname = string.gsub(name, '%.pdf$', something like this will work:'-systems.count') local syco = tonumber(io.loaddata(scname)) or 0
<texcode> for nr = 1, syco do logs.report("LILYPOND","including system no." .. nr) context("\usemodule\setupfloats[lilypondlocation=right,frame=off]\starttext\catcode`placefigure[none]{}{\\externalfigure[" .. string.gsub(name, '%.pdf$', '-=11' .. nr) .. "]}") end end\stopluacode

'''Beware: These relate to the old version of the module and older versions of LilyPond (earlier than 2.7)! Nowadays, LilyPond and epstopdf get called via texmfstart, that works without patching!''' a2 c}
Calling lilypond from command line in Windows fails. (Seems like a bug in lilypond.)\stoplilypond\input tufte
You have two options:\stoptext* 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</codetexcode> 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).== Too many open files ==
LilyPond 2.7.26 comes without a command line With bigger projects and the above setup you might run into "versiontoo many open files"errors, at least in the MacOS X editionLinux, i.eOSX and other Unix-like OSes. Ask your shell about the <tt>lilypond.sh</tt> script is missing.Here's open files maximum and set it's relevant contenthigher:
#!/bin/sh $ ulimit -n ## where was the app installed? 256 INSTALLDIR=/Applications if [ " $1" == "-ulimit -printS -appdir" ]; then echo "$INSTALLDIR/LilyPond.app/" exit 0 fi # where to put the output export LILYPOND_DESTDIR=`pwd` # run the program python "$INSTALLDIR/LilyPond.app/Contents/Resources/lilycall.py" \ "$INSTALLDIR/LilyPond.app/" $@n 2048
Save this as <tt>lilypond.sh</tt>, make it executable and symlink it into a directory on your path, e.g. chmod a+x lilypond.sh sudo ln -s lilypond.sh /usr/local/bin/lilypond== Deprecation ==
=== The old LilyPond stops module (t-lilypond) doesn't work any more with an 'Unbound variable' error ===recent versions of ConTeXt, therefore we removed its documentation here.
The [http://modules.contextgarden.net/t-lilypond LilyPond module] as of 2005-09-12 uses some commands in its header that work only with LilyPond 2.6 (at least no more with 2.7.25); replace "ly:parser-print-score" with "print-score-with-defaults" and "ly:music-scorify" with "scorify-music" for LilyPond 2.7 series.

< [[Graphics]] | [[Using Graphics]] >
[http://www.lilypond.org LilyPond] is a great music engraver, and you can include LilyPond in ConTeXt source using [[moduleshttps:t-lilypond|//github.com/adityam/filter the lilypond filter module]with some setup. This is different from using the lilypond-book preprocessor with LaTeX. (For LaTeX there’s also a package that works similar to our ConTeXt setup here: [https://github.com/jperon/lyluatex lyluatex].)
== 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:
<texcode>
\def\readPDFfile#1{\externalfigure[#1]} \usemodule[filter]\defineexternalfilter[lilypond] [continue=yes, readcommand=\readPDFfile, directory=lilytemp/, % directory for LilyPond's files output={\externalfilterbasefile.pdf}, filtercommand={lilypond-dbackend=eps -ddelete-intermediate-files -o"lilytemp/\externalfilterbasefile" "\externalfilterinputfile"}]
</texcode>
==Multi Page Filter Setup = options ==={| style="border: solid 1px black; padding: 0.5em; vertical-align: top; width: 80%;" |- style="border: solid 1px black; padding: 0.5em; vertical-align: top; background: #eeeeee;"! option !! values !! default !! meaning|-| staffsize || number (pt) || 20 || height of the staff|-| linewidth || measure || <cmd>localhsize</cmd> || width of the staff|-| betweensystemspace || measure || 54pt || space between systems|-| align || yes/no || depends on fragment || ragged-right = (not align)|-| indent || measure || 0pt || first line indent|-| time || yes/no || yes || count the time (i.e. show time signature, draw bars, split the staff)?|-| clef || yes/no || yes || show the clef?|-| fragment || yes/no || no || typeset only a snippet (instead of a whole line)?|-| barnumbers || yes/no || no || show measure numbers?|-| showempty || yes/no || no || drop empty staves?|-| seriffont || "name" || "Century Schoolbook L" || serif font (e.g. for Lyrics and \markup)|-| sansfont || "name" || "LMSans10" || sans serif font (e.g. for chords)|-| monofont || "name" || "Bitstream Vera Sans Mono" || monospace font (normally not used)|}

You can avoid this \include line following [http://modules.contextgarden.net/dl/t-filter/doc/context/third/filter/filter.txt filter module documentation], section "Prepend and append text".
In short: you can inline your complete LilyPond settings or at least the include line:
<texcode>
\startbuffer[lilypond::settings]
\include "mysettings.ly"
\stopbuffer
</texcode>
=== Sample Include File ===
"mysettings.ly" could look like this:

Please look up the meaning of settings in [http://lilypond.org/doc/v2.18/Documentation/web/manuals LilyPond’s great documentation]! If you’d like to exchange measures like text width between ConTeXt and LilyPond, you could write those into the LilyPond buffer.To give LilyPond measures to ConTeXt, you would need to write them into a temp file (using Scheme) and read that in again (useing Lua).For the time being this is left as an exercise to the user. ;) Unfortunately you can’t define LilyPond’s text (lyrics) size with an absolute value, but only relative to staff size... == Font hints Named Buffers == Normally, your LilyPond snippets just get a running number. If you re-order your scores, each one gets re-rendered. You can avoid that if you name your LilyPond snippets: just add <tt>[name=myfunnyname]</tt> to {{cmd|startlilypond}}. If you have just one LilyPond part per component (e.g. songs in a songbook), you could use <tt>[name=\currentcomponent]</tt>.
If you want to know which fonts of set your system LilyPond can see with which namesnote line width automatically to your current text width, try lilypond -dshow-available-fonts any(The 3rd parameter is necessary, but can be anything.)this:
and then adapt your snippets or preamble buffer:
