[http://www.lilypond.org LilyPond] is a great music engraver, and you can include LilyPond in ConTeXt source using [httphttps://modulesgithub.contextgardencom/adityam/filter the filter module] with some setup.net/t-lilypond This is different from using the lilypond module-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:

\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-dtall-page-formats=pdf -dseparate-page-formats=pdf -o"lilytemp/\externalfilterbasefile" "\externalfilterinputfile"}]

==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|-| time || yes/no || yes || count the time (i.e. show time signature, draw bars, split the staff)?|-| clef || yes/no || yes || show the clef?|-| 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 measure numbers?|-| 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)|}

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 -dtall-page-formats=pdf -dseparate-page-formats=pdf -daux-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}, ...]

</texcode> Please look up the meaning of settings in [http://lilypond.org/doc/v2.24/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). To give LilyPond measures to ConTeXt, you would need to write them into a temp file (using Scheme) and read that in again (using 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. == 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>. == Automatical width adaption == If you want to set your note line width automatically to your 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>\stoplilypondinclude "../mysettings.ly"\include "texsettings.ly"

You must comment/delete the "line-width" setting in mysettings.ly, otherwise it won’t work. == Font hints Example == Here's an example of placing score snippets in the body of the text, with fonts in the score & body matching: <texcode>\def\LILYTEMP{lilytemp} % name of folder for LilyPond/buffer files \def\ParseLilypondFile#1% #1 is the name of the output file {\ctxlua{thirddata.parselilypondfile("#1")}} \startluacode thirddata = thirddata or {}

LilyPond depends on the fonts that pango/fontconfig can find. But -- create temp folder if missing if not even all of those will work, elfs.gisdir("\LILYTEMP") then lfs. no fonts from the TeX tree mkdir(don't know why"\LILYTEMP"), only one face per font file etc.Therefore it doesn't use ConTeXt's font setup. end

If you want to know which fonts of your system LilyPond can see with which names, try function thirddata.parselilypondfile(name) -- include all systems (pages) lilypond -dshow-availablename is like \LILYTEMP/mainfile-fonts anytemp-lilypond-21.pdf logs.report(The 3rd parameter is necessary"LILYPOND","name='" .. name .. "'") local scname = string.gsub(name, '%.pdf$', but can be anything'-systems.count') local syco = tonumber(io.loaddata(scname))or 0

LilyPond for nr = 1, syco do logs.report("LILYPOND","including system no." .. nr) context("\\setupfloats[location=right,frame=off]\\placefigure[none]{}{\\externalfigure[" .. string.gsub(name, '%.pdf$', 's default text font is Century Schoolbook-' .. nr) .. You can use it in ConTeXt like this:"]}") end end\stopluacode

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:
