Beware that the version you interpolate can only be trusted upon if you use git 
also to determine the ‘added/modified files’ state and take the 
‘with-local-modifications’ state into account in your interpolation (either by 
not putting the git version in, or by indicating that it is a locally modified 
state derived from a certain git version)

Ah, that one. Thank you. Now set.

If the path is in |/tmp/|, it means that you did not save your file 
before compiling, so Frescobaldi put the contents of the current editing 
window in a temporay file and compiled that.


If you simply remember to always save before compiling (or turn on 
save-on-compile in the preferences), Frescobaldi will compile your file 
with the directory where it's saved as the current directory. If that's 
inside a Git repository, |git| commands should work.

Thank you for the very  prompt response. I had tried popen, but with no 
luck. I will give it another go.I do not now remember what it originally 
said, if anything.


[Later] The error I am getting now is:
Processing `/tmp/frescobaldi-duowk0s5/tmpz726e77a/testGit.ly'
 Parsing...fatal: not a git repository (or any of the parent 
directories): .git


So, after a bit of faffing around for how to change the TMPDIR in the 
GUI, I changed my whisker-menu (Ubuntu/xfce4) entry to	

bash -c "TMPDIR=$HOME/src/Music/tmp frescobaldi %F"

Doing just
TMPDIR=$HOME/src/Music/tmp frescobaldi %F
did not work.

Lilypond.


How does it fail? It should definitely work. It will just not capture 
the output. See LSR 567  for a 
snippet that uses |open-pipe*| from |(ice-9 popen)| to achive 
essentially the same need as yours.


I realise that being able to do so opens up a massive security hole, 
but that is not a problem here.


LilyPond does not attempt to securely compile the file if it untrusted. 
(There used to exist a |-dsafe| option, but it was found to be 
irreparably broken, and got removed.)
