Jonathan > thank you for the remarks and for the samples too.
Neil > I corrected this small bug, indeed the script didn't care of the
options you fed it with. And if you prefer nederlands default output,
just change in lilymusic.py line 38
lily_out_style = "italiano"
into
lily_out_style = "nederlands"
For today, I give up finding an easy way to parse a complex .ly file...
i'll try later :D
Nevertheless, the script should run better. To launch it, you may copy
the part containing only the notes into a separate file
ex : from
clarinet = { ... } or \new Staff {... }
extract { ... } (with the braces) and copy into a new file
to use it :
python lilymusic.py --out_style="nederlands" < test.ly > new.ly (thx carl)
to download it (new version) :
http://dl.free.fr/pXHJyTc5P
+ handle comments and multiline comments
+ put a \include "italiano.ly" on top according to the chosen style
! corrected bug : you can now use --out_style
TODO
- handle properly \key indications

This is a good idea, Yota. I was going through some of my first
Lilypond files today and found that I had written them in absolute
mode and wished I'd had a script to convert them to relative. I did
them by hand since they were very short, but for anything longer, a
script like yours would be very helpful.
I ran your script on the test file "in.ly" included in your archive
and it seemed to work fine (the absolute pitches were changed to
relative) but then I couldn't get the resulting file to compile in
lilypond. I worked on it for a few minutes but couldn't find the
problem and gave up.
I also ran the python script on one of my own files and had problems
with it. First of all, it doesn't seem to recognize comments
properly, as it goes through my comments changing them as if they were
pitch indications. It did the same thing to the title in my Header
block and even added a stray { that caused errors when trying to
compile. Also, I use the default Dutch pitch names, and while it read
them correctly, it also changed them to the Italian pitch names in the
conversion process.
I wish I could help tweaking the code, but I have no idea how to write
in Python. I'll be glad to test the script out when you make changes
to it, though. Hope it helps to see these samples.
Best,
Jonathan

Good evening everybody,
Being unable to find a nice tool to handle lilypond sources, I
designed mine.
I worked on this little script which (even if its buggy) should
perform some essential tasks:
- convert absolute music to relative music
- transpose the source (from bes to c for example)
- change the naming scheme
in the future I hope it will also
- shrink R1 R1 R1 R1 R1 R1 R1 R1 R1 R1 R1 stuffs into R1 * 11
the parser is very naive and need to be improved, but the code should
be flexible enough to let some room for improvements.
if you wanna play with it, download it from
http://dl.free.fr/mQx7nFhQQ , expand it and use python. The main
script is lilymusic.py ; to be feeded from the stdin.
ex : cat in.ly | python lilymusic.py
feedback appreciated
... now goin' to bed
