[JW Lua] Antw.: How to mark objects to be excepted from automatic processing?

[Bart Visser]

Hi Thomas,

I can think of three options, which you've probably thought about yourself as well (but I write it down anyway :-)).

1. Add an Expression-category, and move those expressions that you want to be left alone (not a very good solution, but it should work)

2. Add something to the comment-field of the Expression. This isn't displayed anywhere but can be read (and altered) by JW Lua.

3. A more troublesome way could be to create a hidden page-text where you add the ID's of the expressions you want to be left alone. You could even delete the page-text, it keeps it's value as a FCTextBlock, but is not visible in the score. I've experimented with something like this when I a script to read certain PageText-properties, uniq to the file. I've made a script write a json-string to a hidden PageText and could read the json-string back into another script that needed the values.

Maybe this helps. I'm interested to hear what you come up with in the end.

Cheers,


Bart Visser
