Re: Global Variable vs Edition Engraver

[Craig Dabelstein]

Hi gents,

Thanks for your advice. Jan-Peter, I do something similar with a global "timeline" or structure with barlines, key signatures, repeats, rehearsal marks. I was just wondering if I was behind the times and not keeping up with the EE. I'm just trying to make my code as concise as possible.

Thanks guys,

Craig

Hi Craig, Kieren,

I actually use kind of a global variable for the global time line. So
all repeat signs, time-signatures *and* key-signatures there. Before I
implemented the EE I started with a template-engine where the tamplates
take care of creating the simultaneous music ( << \getMusic meta
\getMusic instrument >> ):
https://github.com/openlilylib/lalily-templates

It takes care of transposing instruments per score. I guess I have to
deal very seldom with changing instruments inside a movement compared to
you. Though it should be possible with an auto-transposer that tracks
for changing transpositions. That way the change of the instrument is
only a matter of setting properties and therefore would be EE compatible:
(I don't remember the state of this snippet ...)
https://github.com/openlilylib/snippets/tree/master/editorial-tools/auto-transpose

Btw, if I am transcribing a piece rehearsal marks found in the original
are placed in that global variable. For other pieces where I insert
rehearsal marks as an editorial addition I use the EE.

Best,
Jan-Peter

I've been using the EE since Jan-Peter let it out of his private stash (aka "Day One"), and I'm still moving stuff over to the EE pile on an ongoing basis. Most recently, I've moved all rehearsal marks and barlines to my EE code; the move before that was clefs.

If you’re putting together a one-page lead sheet for a jazz song, I'm not sure you need the overhead; if you’re putting together an opera with upwards of a dozen different score targets, etc., then it’s almost certainly worth putting *most* things in the EE.

In the musical theatre world, where pit musicians (esp. wind players) can have 6 or more transposing instruments of different kinds and transpositions in a single book, this is a huge question that I still need to answer definitively.
