How can a user, who wants to use e.g. the measure counter engraver, change the partCombineListener' s Global context without messing with the original lilypond sources? Am I missing something? The whole point of scheme engravers and scheme text spanners is that users can now also implement things in scheme without messing with the lilypond sources... If I understand you right, then the user cannot add new grobs in an include file without messing with the lilypond sources. Would a proper solution be to change the partCombineListener to a context mod and construct the real listener when we need it (i.e. replace the current (ly:parser-lookup parser 'partCombineListener) by the actual creation of the listener from the context in effect when add-quotable or recording-group-emulate is called? However, I don't really have enough knowledge about how to create the actual listener in scheme and insert a given context mod in scheme...
