I found lilypond mentioned on the list, downloaded lilypond-2.10.23-1.darwin-x86.tar.bz2 from lilypond.org, t-lilypond.pdf from ctan and t-lilypond.tex posted by Henning here. When I typeset texexec test.test this test file ... \usemodule[lilypond] \starttext \startlilypond % Telemann, TWV 40:11 \version "2.6.3" \relative c’ { \set Staff.instrument = flute \key fis \minor \time 3/4 \partial 4 r8 fis’8 | fis4. cis8 a cis | fis, a cis fis a fis | b, d fis b d b | eis,, gis cis eis gis b, | a fis’ gis, fis’ cis eis | fis,4 r8 a’ gis fis | e gis, a e’ fis cis | d fis, gis b e d | cis4 \trill r8 cis b a | b dis e gis cis, b | a e’ dis fis b, a | gis4 \trill r8 } \stoplilypond \stoptext ... the result is ... name: dummy file: lilypond_2-lilypond-1 state: unknown What is missing?
