Hello, In order to speed up the compiling time, I wonder if Lilypond has a preprocessor that can filter all the parts of the score which aren't marked by a specific tag.
So, for example, the following code could be compiled only for the chunks included between \START and \END tags: %%%%%%%%%%%%%%%%%%%%%%%% \START { \END % This will be filtered d' d' d' d' \START c' c' c' c' \END % This will be filtered d' d' d' d' \START } \END %%%%%%%%%%%%%%%%%%%%%%%% Is there anything already built-in in Lilypond for this? Of course it is trivial to make a script for doing the job, but it would be desirable if Lilypond already had this feature... Best, P
