Re: How to append a git version to an output filename

[Noeck]

Hi,

when I've seen the inclusion of git information on lilypondblog [1], I
liked it and adapted it to my taste:

Of course one can include a whole git log in the score, but the only
thing I was interested in is this: If I have a printed score or a PDF, I
want to know which version that was. All the rest I can look up in git.
And the versioning, I do with tags because I like it more than
hexadecimal hashes.

I have a tag for each year and each commit since then is counted, so
what I write on the score looks like:

   Version 2018.25

It's derived from `git describe`, the full command is:
git describe --long --dirty='+' | sed 's/-/./' | sed -r 's/-g[0-9a-f]+//g'

I like the combination of `git describe` and tags a lot. That's my
personal optimum between usefulness and beauty for both technical and
non-technical readers of the score.

Cheers,
Joram
