LyX and LilyPond

[Matthew Isam]

 Thank you to Koji Yokota about some suggestions.My issue was I was trying to get Lyx to auto detect everything and it does not see to want to do that, at least in my case, with 2.26.0.
To setup everything, extract lilypond 2.26.0 someplace. Note the path.
In lyx preferences, file handling, converters find the current entries for lilypond-book or add them if missing. The defaults are below. In each case, I used the bundled with lilypad python, not the system version. Each time you make changes on a converter, be sure to hit "modify" button to save it, and then OK when done. This means I replaced "lilypond-book" in each of the default converters to something like this:
C:\\path\\lilypond-2.26.0\\bin\\python.exe  C:\\path\\lilypond-2.26.0\\bin\\lilypond-book.py
Note I had to use two backslashes.
An example would convert:lilypond-book --latex-program=dvilualatex --lily-output-dir=ly-eps $$i
into this: C:\\path\\lilypond-2.26.0\\bin\\python.exe  C:\\path\\lilypond-2.26.0\\bin\\lilypond-book.py --latex-program=dvilualatex --lily-output-dir=ly-eps $$i

Last, I edited the path in the lyx settings to also have  C:\path\lilypond-2.26.0\bin\
This gave me all the things I needed. The example file with Lyx shows previews and will render to PDF correctly. My own documents work now as well.
Default converters:lilypond book latex =>dviluatex
lilypond-book --latex-program=dvilualatex --lily-output-dir=ly-eps $$i

lilypond book latex =>luatex
lilypond-book --pdf --latex-program=lualatex --lily-output-dir=ly-pdf $$i

lilypond book latex =>pdf latex
lilypond-book --pdf --latex-program=pdflatex --lily-output-dir=ly-pdf $$i

lilypond book latex =>plain
lilypond-book --lily-output-dir=ly-eps $$i

lilypond book latex =>xetex
lilypond-book --pdf --latex-program=xelatex --lily-output-dir=ly-pdf $$i

lilypondsbook platex -> latex playtex
lilypond-book --pdf --latex-program=platex --lily-output-dir=ly-pdf $$i
Thank you for your  help and hope this post helps others.

 Hi Matt,


To get the error to stop on opening the sample I added a converter for lilypond-book(latex)->Latex(plain) and giving it a path like this:$${python}  C:\path\lilypond-2.26.0\bin\lilypond-book.py  $$iorC:\pathtopython\python.exe  C:\path\lilypond-2.26.0\bin\lilypond-book.py  $$i

This looks like a symptom that LyX could not find lilypond. If LyX’s configuration works via Tool->Reconfigure, this need not be set manually.

Once I found 2.20.0-1 on the Lilypond site and installed, put in the path, reconfig I did not have any errors going into the sample LilyPond guide, but still had errors on rendering.

I’m not sure if this helps, but there seem cases that conversion to get pdf from lilypond via dvipdf or its variants fails. Using other paths, e.g. pdflatex or lualatex, may solve the problem.
To use LuaTeX, check Document -> Settings -> Font -> Use non-TeX fonts and choose Document -> View PDF (LuaTeX) when output PDF.
Looking into errors more precisely, running Japanese example file LilyPond_Book.lyx via dvipdf gets the following error raised by dvipdf:

>(Image:./5e/lily-71e9560f-1.eps[PS]Error: /invalidfileaccess in --file—Last OS error: Permission deniedCurrent file position is 409GPL Ghostscript 10.07.1: Unrecoverable error, exit code 1

Ghostscript complains because the following command fails because the file name is single quoted.

rungs -v -dSAFER -dNOPAUSE -dBATCH -dEPSCrop -sPAPERSIZE=a0 -sDEVICE=pdfwrite -dCompatibilityLevel=1.7 -dAutoFilterGrayImages=false -dGrayImageFilter=/FlateEncode -dAutoFilterColorImages=false -dColorImageFilter=/FlateEncode -dAutoRotatePages=/None -sOutputFile='/var/folders/68/mx20w3b146vgt6yfjqlh5gxm0000gn/T/dvipdfm-x.f14af449408d798d54229786a68c3552' -- './5e/lily-71e9560f-1.eps’

I cannot confirm this phenomenon with the English example file, so it may be related to the use of UTF chars.
Koji
