Hi all,
I'm looking for a solution to conditionally include a file
if it exists
Oops.
Well, the question is real, but of course I intended to add
more to it ...
The idea is to include a file with a number of music variables
and then include files that contain one music variable each,
overriding one variable from the first included file.
So if no file is included the (empty) variable from the first
file is used, otherwise the individual variable from the
single file.

A first approach may point in a direction, although it doesn't
work at all.
please consider the attached files: collect.ly tries to include 01
through
#(ly:parser-parse-string
(ly:parser-clone parser) "\\include \"01.ily\""))
(an approach that worked successfully in another situation).
But obviously it doesn't understand the content of 01.ily, as I
get
01.ily:4:3: error:
unrecognized string, not in text script or \lyricmode
c d e f g
errors (and subsequently one more for each of the notes).
So how can I include a file containing music
variables through Scheme (in order to generate the filenames to
be included programatically)?
TIA
Urs
