Question (solutions below)

With version 2.24 there seems to be no more lilypond-windows.exe, which (without having to know details) did create PDFs, and/or in case of errors log-files.

Now, using v2.24, I have to link .ly-files to lilypond.exe. which works fine, even by doubleclicking .ly-files, but only if these files do not contain fatal errors. Otherwise all error messages disappear together with the command-line that appears for a split second, and no other output is generated. I would create a decent command with options for that, but the documentation on command line usage seem to be meant for Liunx users only since several options I tried in command line are answered with error messages.

lilypond --log-file [...] -> unrecognized option --log-file

lilypond -log-file [...] -> unknown log-level og-file (which I understand)

lilypond file.ly &>all.log -> "syntax error"

I don't use Frescobaldi as in the installation guide, for now I wanted to keep going with Notepad++ and use only the lilypond framework as I did before.

I'm not sure, if this part of Stack Exchange is the appropriate one, but my experience shows, that there are a lot of you knowing much more than just the basic usage of lilypond. I'd appreciate any help.

Possible solutions

1. using the answer from @Lazy I wrote a batch file lily.bat you can drag your .ly-file on, and which does the following:

  • change to my Lilypond directory
  • execute lilypond with generating a log file in the folder of the .ly-file
  • move the generated music-sheet PDF (if it exists) from the lilypond folder to the folder of the .ly-file
cd "\Lilypond 2.24.0\bin"
lilypond.exe %1 1>"%~dpn1".log 2>&1
if exist "%~n1".pdf ( move "%~n1".pdf "%~dpn1".pdf )

2. using the answer from @ABOU SAMRA Jean I made a shortcut from lilypond.exe, you can drag your .ly-file on.

  • In the shortcut-properties I specified the target as "G:\Lilypond 2.24.0\bin\lilypond.exe" -dlog-file=out"
  • In the field Start in I simply put %cd%

This generates the music-sheet PDF and a log file in the folder of the .ly-file. Unfortunately, for the log-file's name I (due to a pure lack of knowledge) cannot use the name from the .ly-file. If anyone knows how, I gladly edit this section again.

    The expansion flags can be combined, you don't need to write "%~d1%~p1%~n1", only %~dpn1.

The log-file option is documented here: https://lilypond.org/doc/v2.24/Documentation/usage/command_002dline-usage.html#advanced-command-line-options-for-lilypond. As explained at the beginning of that section, the correct syntax is

lilypond -dlog-file=x file.ly
  • Thank you! This is a line that can be used in windows shortcuts and is therefore my favourite method. It still isn't perfect, but nevertheless my favourite solution. (Details in my initial questions - I added your answer as a possible solution to my question)

  • Just as an explanation: Both answers are equally usable and I had a hard time to decide which answer should be "the one". But since I seem to be using this solution now, I vote for this one. No other reason.

lilypond.exe file.ly 1>all.log 2>&1 should do it I believe.

  • Does Windows recognize that syntax? That's something that would work in bash or other Unix shells, but I wouldn't expect it to work in Windows.

  • @Ramillies Yes, it does.

  • This works and I used it in a batch file (.ly-file can be drag&dropped). I added this as a possible solution to my initial question. Thank you!
