Re: Defining a variable for path names

I have two different versions of each of my lilypond files, each with a
different header.  At the top of each file, I have this:

\include "C:/songs/lilypond_header_file_1.ly"
%\include "C:/music/lilypond_header_file_2.ly"

I'd like to be able to use a global variable that is set in only one place
(maybe somewhere in C:\Program Files
(x86)\LilyPond\usr\share\lilypond\current\ly) 

Do *not* store such a configuration inside the LilyPond installation because it would be trashed when you uninstall or update LilyPond.
Use a location in your documents folder instead.

to determine which header file
to use.  That way, at the top of each file I could write something like

\include "$header_file"

and I would know that whenever I compile a given file, it would use the
header file that I specified.

How do I do this?

It's actually quite easy.

Write

\include "C:/songs/lilypond_header_file_1.ly"
%\include "C:/music/lilypond_header_file_2.ly"

in a file "lilypond_header.ily"
and save that in a central place where you want to maintain this choice (e.g. the toplevel directory where you store all your LilyPond projects).

In any actual music file simply write

\include "C:/path/to/lilypond_header.ily"

This way all your scores refer to that central configuration file, and you can edit this file to make all scores use one or the other header file.

Thanks.
