Hi, Rick! Yes, this preprocessor looks scary, as well as some advanced
programming with Scheme. But once I got into reading about the GEMA
preprocessor and didn't look as complicated as m4. Maybe it's worth a try.
Another thing I found out that is *really* useful with text editing,
manipulating: Learn Regular Expressions. You can do quite a few tricky
search
and replace tasks. And most of text editors for programmers support them.

Thanks Eduardo,
I am liking the GEMA pre-processor, here is how I implememnted snippet
libraries of canned lilypond code that can be macroized and for
inclusion in lilypond source.
SAMPLE chord library GEMA definition (the macro parameters are root,
chordname, duration with a period delimiter):
GEMA_Chord * * *.=\\transpose c $1 \{ \\relative \{\
\
@cmpi{$2;Maj7;; c e g b;}\
@cmpi{$2;Maj7_1;; c\5 g' b e;}\
@cmpi{$2;6;; c e g a;}\
! etc, etc, etc...\
\
$3 \} \};
SAMPLE of what the lilypond source would look like prior to GEMA resolution:
GEMA_Chord c Maj7 4.
GEMA_Chord c 6 4.
SAMPLE of what GEMA resolves (output to be compiled by lilypond):
\transpose c c { \relative { c e g b4 } }
\transpose c c { \relative { c e g a4 } }
This is much easier than scheme music functions for generating lp source
code. GEMA was pretty easy to figure out how to use by a non-programmer
(like me), in about 2 hours time I was able to make the above chord library
macro. I only have to now change my build scripts to run GEMA ahead of
lilypond. To keep my LP code cleaner I'm prefixing all my future macros
with GEMA_.
In my sample above the @cmpi functions act like a big CASE statement to
output the desired music based on the second parameter (chord name). The
first parameter (the chord root) is appended to a \transpose statement. The
last parameter (the duration) is appended behind the generated notes. In my
chord library I only need to state each chord inversion once (with roots of
c). I expect the library to have a thousand different inversions eventually
so this will help in future productivity in generating chords for all
purposes.
Thanks again
Rick

Has anyone extended \include?
Has anyone on this list extended the \include lilypond command to also do simple token replacement as it is including the text? IOW like this: \include myFile.ly @myToken1=a; @myToken2=25; @myToken3=replace with this Whereby @myToken1, 2 and 3 above will be whole word searched and replaced with the data between the = sign and semi-colon. Or similar? Kind of like a smart \include? If you have done this can you share it or sell it to me?

I know of regular expressions and use them in my text editor searches, etc. but this is more along the lines of making my lilypond music code itself more flexible, I'm happy with many different editors and am trying to avoid creating my lilypond music code libraries in any specific editors snippet library. I'd prefer to keep my libraries as lp \include files, but at some point I'm always needing some pre-processing of the source text prior to lp compilation. Be it token replacement (to change \key perhaps), or a Case statement to \include a parameterized chord inversion selection from a library of chords, etc. -- View this message in context: http://www.nabble.com/Has-anyone-extended-%5Cinclude--tf2871492.html#a8026572 Sent from the Gnu - Lilypond - User mailing list archive at Nabble.com. ___ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user

I use in my scores some functions called \includeScore, \includeNotes,
\includeLyrics, etc. You can look at the sources at
http://nicolas.sceaux.free.fr/lully/ or this article:
http://nicolas.sceaux.free.fr/index.php/2006/06/29/9
The LilyPond distribution has a function that makes a conditional
include: see \includePageLayoutFile in ly/music-functions-init.ly.
But then, there is no textual replacement when parsing LilyPond file;
instead you should use variables.
%% The function definition:
myInclude =
#(define-music-function (parser location filename bindings)
(string? list?)
..set some variables and include the file..
(make-Music 'SequentialMusic 'void #t))
%% Function usage:
\myInclude foo.ily #'((myPadding . 4)
(myString . hello)
(myMusicPattern . #{ c d e f #}))
%% foo.ily:
\score {
\new Staff {
\override TextScript #'padding = \myPadding
s0^\markup \italic \myString
\repeat unfold 4 \myMusicPattern
}
}

Re: Has anyone extended \include?
Thanks, Browsing the manual GEMA looks like it could work to do both substitution and conditional outputting, I'll try it.
