Hi Aditya et.al.,
I'm using t-filter with LilyPond for my songbooklets like this:
-----
\def\readPDFfile#1{\externalfigure[#1]}
\usemodule[filter]
\defineexternalfilter[lilypond]
[continue=yes,
readcommand=\readPDFfile,
directory=lilytemp/,
output={\externalfilterbasefile.pdf},
filtercommand={lilypond -dbackend=eps -dinclude-eps-fonts -dno-gs-load-fonts -o"lilytemp/\externalfilterbasefile" "\externalfilterinputfile"}]
-----
Now, I'd like my lilypond sections/buffers to have different names than just numbers; I'd prefer some unique IDs or even manually set names to be able to re-order them without the need of re-compiling.
I.e. if I change the order of songs in my songbook, all LilyPond snippets must get recalculated, even if they didn’t change.
Sorry if that’s mentioned in t-filter’s docs - I didn’t see it.
There are some more enhancements that I’d like to implement, e.g. checking the resulting files if there are several pages or using single notelines to let ConTeXt do the page breaking (like lilypond-book does with LaTeX). I guess that would be as simple as replacing my \readPDFfile with some Lua code - can you give me a hint how to do that?
Greetlings, Hraban

Does
\startlilypond[name=one]
....
\stoplilypond
what you are looking for? (see the docs for how this behaves behind the
scenes)

See grph-inc.*. I'll post an example later on how to handle single page
and multipage pdfs differently.

Oh, so simple? Great, that’s exactly what I meant. Since I would normally set [name=\currentcomponent], can I make that default?

Thanks, handling of multipage PDFs might help, but I’d try a different approach: LilyPond can generate EPS/PDF for single note systems and writes the number of them into a simple text file. I’d parse that with Lua and place all those small PDFs. I just need a clue how I must define t-filter’s "readcommand" as a Lua function.

Unfortunately no. The name key is reset at every `\startexternalfilter`;
otherwise it will be difficult to mix `name=....` with normal usage.

Something like this:
\def\ParseLilypondFile#1%
% #1 is the name of the output file
{\ctxlua{thirddata.parselilypondfile("#1")}
\startluacode
thirddata = thirddata or {}
function thirddata.parselilypondfile(name)
--- parse "name" file as you wish and
--- generate approapriate context(...) commands
--- to write back to ConTeXt
end
\stopluacode
\defineexternalfilter[lilypond]
[
.....
readcommand=\ParseLilypondFile,
....
]

What do you think about using UIDs (or maybe some hash value of the buffer) instead of serial numbers? It might help with other uses of t-filter to be able to re-order the filter sections without re-compiling.

Thank you very much! It’s been a while since I wrote my last Lua code for ConTeXt...
I’ll just update the LilyPond wiki page (and then delete everything about the old LilyPond module).
