[http://www.lilypond.org LilyPond] is a great music engraver, and you can include LilyPond in ConTeXt source using [httphttps://modulesgithub.contextgarden.netcom/adityam/t-lilypond 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: [[Imagehttps:T-lilypond//github.tex]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:

\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"}]

==Multi Page Filter Setup = options ==={| style="border: solid 1px black; padding: 0.5em; vertical-align: top; width: 50%;" |- 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|-| time || yes/no || yes || show time signature?|-| align || yes/no || depends on fragment || ragged-right = (not align)|-| fragment || yes/no || no || typeset only a snippet (instead of a whole line)?|-| barnumbers || yes/no || no || show bar numbers?|}

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) .. "]") end end\stopluacode \usemodule[filter]\defineexternalfilter[lilypond] [continue=yes, cache=yes, readcommand=\ParseLilypondFile, directory=\LILYTEMP/, output={\externalfilterbasefile.pdf}, filtercommand={lilypond -dbackend=eps -ddelete-intermediate-files -o"\LILYTEMP/\externalfilterbasefile/" "\externalfilterinputfile"},]

E.g. for == LilyPond Settings == Collect your LilyPond settings in a songbook you want to place big chunks of LilyPond output (i.e. note staffs) ly file, put it in your text. It behaves lilytemp directory and include it from within your lilypond block like any other graphics, especially similar to embedded [[MetaPost]] codethis:

\relative { \repeat volta 2 { \partial 4 e4 | a2 c4 d | e2 f4 e | d2. c4 | b4. c8 d4 e | a,2 c4 d | e2 f4 e | g,2 a | \partial 2. b2. | } \repeat volta 2 { \partial 4 r4 | f' g f d | e f e c | a b c d | e2include "mysettings. e4 | f g f8 e d4 |ly" e f e c | a c b8 a g4 | } \alternative { { \partial 2. g2. } { \partial 2. a2. } }}

There's nothing to say about this tune yet; my friend heard it from Lúnasa\defineexternalfilter[lilypond][ ... bufferbefore={lilypond::settings}, ...]

== Developer's Corner ==Please look up the meaning of settings in [http://lilypond.org/doc/v2.22/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 (see below).

For information how the integration worksTo give LilyPond measures to ConTeXt, please check the module code you would need to write them into a temp file (using Scheme) and its pdf version read that in again (both available from [http://modules.contextgarden.net/t-lilypond]using Lua). Unlike lilypond-book for LaTeX, For the module does not use a precompiling step and thus can react time being this is left as an exercise to local width changes and the like, even if the lilypond code is stored in a bufferuser.;)

Things that have not been implemented yet include:* set the Unfortunately you can’t define LilyPond’s text font (default should be ConTeXt's bodyfont instead of LilyPond'slyrics)* make lilypond call back on ConTeXt for included TeX (cfsize with an absolute value, but only relative to staff size. [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* LilyPond variables

To remember:* see [http://lilypondNormally, your LilyPond snippets just get a running number.org/doc/v2If you re-order your scores, each one gets re-rendered.9/Documentation/ LilyPond Docs]!* How do we handle version/syntax changes of LilyPond?

--You can avoid that if you name your LilyPond snippets: just add <tt>[[User:ChristopherCreutzig|Christopher Creutzig]name=myfunnyname] after ideas by [[User:Hraban</tt> to {{cmd|Hraban]]startlilypond}}.

If you have just one LilyPond part per component (e.g. songs in a songbook), you could use <tt>[name== Tweaks ==\currentcomponent]</tt>.

At the moment it's not possible == Automatical width adaption == If you want to set your note line width automatically to change LilyPond's fontsyour current text width, try this:  -- this goes after "create temp folder" io.savedata("\LILYTEMP/texsettings.ly", "\\paper { line-width = " .. string.gsub(number.todimen(tex.dimen.textwidth),"pt","\\pt") .. " } \n") and then adapt your snippets or preamble buffer:<texcode>\include "../mysettings. The text font is Century Schoolbookly"\include "texsettings. ly"</texcode> You can use must comment/delete the "line-width" setting in mysettings.ly, otherwise it as ConTeXtdoesn’t work. == Example == Here's default font like thisan example of placing score snippets in the body of the text, with fonts in the score & body matching:

You have two options:\score {* modify the module, so that lilypond is called with the whole path ( <code>C:/prog/lilypond/usr/bin/lilypond</code> for example instead of \new Voice = "mel" { \autoBeamOff \melody } \new Lyrics \lyricsto mel \text \new PianoStaff <<code \new Staff = "upper" \upper \new Staff = "lower" \lower >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 \layout { \context { \Staff \RemoveEmptyStaves } }}

LilyPond 2.7.26 comes without a command line "version", at least in the MacOS X edition, i.e. the <tt>lilypond.sh\stoptext</tttexcode> script is missing.Here's it's relevant content:

#!/bin/sh ## where was the app installed? INSTALLDIR=/Applications if [ "$1" =Too many open files = "--print-appdir" ]; then echo "$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/" $@

Save this as <tt>lilypond.sh</tt>, make it executable With bigger projects and symlink it the above setup you might run into a directory on your path"too many open files" errors, at least in older Linux, e.gOSX and other Unix-like OSes. chmod a+x lilypond.sh sudo ln -s lilypond.sh /usr/local/bin/lilypondAsk your shell about the open files maximum and set it higher:
