fix link of filter module
< [[Graphics]] | [[Using Graphics]] >
[http://lilypond.org LilyPond] is a great music engraver, and you can include LilyPond in ConTeXt source using [[moduleshttps://github.com/adityam/filter|the 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 ==
directory=lilytemp/, % directory for LilyPond's files
output={\externalfilterbasefile.pdf},
filtercommand={lilypond -dbackend=eps -dno-gs-load-fonts -dinclude-eps-fonts -ddelete-intermediate-files -o"lilytemp/\externalfilterbasefile" "\externalfilterinputfile"}]
</texcode>
directory=\LILYTEMP/,
output={\externalfilterbasefile.pdf},
filtercommand={lilypond -dbackend=eps -dinclude-eps-fonts -dno-gs-load-fonts -o"\LILYTEMP/\externalfilterbasefile" "\externalfilterinputfile"}]
</texcode>
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
\defineexternalfilter[lilypond][
...
bufferbefore={lilypond::settings},
...]
</texcode>
=== Sample Include File ===
<texcode>
\version "2.1618.02"
#(ly:set-option (quote no-point-and-click))
#(set-global-staff-size 14)
\override PaperColumn #'keep-inside-line = ##t
}
% some example settings
\context { \Staff
\override TimeSignature #'style = #'numbered
Normally, your LilyPond snippets just get a running number. If you re-order your scores, each one gets re-rendered.
You might want can avoid that if you name your LilyPond snippets: just add <tt>[name=myfunnyname]</tt> to add <cmd>startlilypond</cmd>. 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(or name"\LILYTEMP/texsettings.ly", "\\paper { line-width =mymusic" .. string.gsub(number.todimen(tex.dimen.textwidth),"pt","\\pt") .. " } \n") to and then adapt your snippets or preamble buffer:<cmdtexcode>startlilypond\include "../mysettings.ly"\include "texsettings.ly"</cmdtexcode> to avoid unnecessary re You must comment/delete the "line-renderingwidth" setting in mysettings.ly, otherwise it doesn’t work.
