[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-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 -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/v2.18/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...

Things that have not been implemented yet include:* set the text font (default should be ConTeXt's bodyfont instead of Normally, your LilyPond's)* make lilypond call back on ConTeXt for included TeX (cfsnippets just get a running number. [http://lsr.dsi.unimi.it/LSR/Item?id=107])* get information from lilypond about the baselineIf you re-order your scores, for runeach one gets re-in music fragments* tell lilypond how much space is left on the first page* check and probably work on proper multi-page music* LilyPond variablesrendered.

You can avoid that if you name your LilyPond uses fontconfig for font search. At least on MacOS X it's very restricted what kind of fonts it can use - only single-style TrueType (including dfont). I didn't manage yet to use fonts from the TeX tree. (That doesn't seem snippets: just add <tt>[name=myfunnyname]</tt> to be fontconfig's fault - it writes appropriate font cache files everywhere<cmd>startlilypond</cmd>.)

To remember:* see [http://lilypondIf you have just one LilyPond part per component (e.org/doc/v2g.9/Documentation/ LilyPond Docssongs in a songbook), you could use <tt>[name=\currentcomponent]!* How do we handle version</syntax changes of LilyPond?tt>.

At the moment it's not possible to change LilyPond's fonts -- this goes after "create temp folder" io.savedata("\LILYTEMP/texsettings.ly", "\\paper { line-width = " .. string.gsub(number. The text font is Century Schoolbooktodimen(tex. You can use it as ConTeXt's default font like this:dimen.textwidth),"pt","\\pt") .. " } \n")

You must comment/delete the "line-width" setting in mysettings.ly, otherwise it doesn’t work. == 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 {}  -- 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 ..

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

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

=== 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.
