I'd treat a user's magic comment the same as other magic comments
as a bit more consistent.
While I can appreciate this viewpoint, I have the problem of wanting
to use these for control information - and thus have a validity issue.
BUT, if the user does an Undo followed by a Redo, I have problems -
how to get the protected versions of the styles applied? Since I am
blocked from receiving the [e.g.,] SC_MOD_CHANGESTYLE and restyling
magic comment sequences SYNCHRONOUSLY, I am in a bad spot (I think).
Run the fix up asynchronously. That can cover both user cast magic
and user undo/redo.
You keep saying this (or close variations), but while Windows messages
and messaging are things I find easy to use, my app is using the GTK
widget version of Scintilla, and I do not really have a clear picture
of a) how async messaging would work in this environment, or b) if any
approach would work on all the platforms where GTK is nominally
supported. Besides, explicitly asynchronous control logic can be
headache-inducing (particular when not really necessary).
OTOH, you *could* consider allowing *style* modifications to nest
(like markers) - the code (in Document::SetStyleFor() and
Document::SetStyles()) didn't look too far from being workable already
- I just am a bit unclear about how to handle endStyled.
Key to both of these, of course, is to still track enteredCount, and
be smart about issuing notifications - maybe only allow one level of
recursion, and decide to call NotifyModified a) the first time, or b)
both times, depending on how things will work with nesting (or not)
Redraw() or InvalidateRange() calls... we certainly do not want any
endless loops. :)
I can whip this up too, although a sage word or two regarding
endStyled would be nice.
So I *could* wipe the Undo stack (setting a Save Point is the
equivalent for my app) right after "officially" inserting one or more
of the magic sequences... no Undo to worry about! Is this reasonable,
or too extreme?
If I was your user I'd hate you.
Hey, desperate times call for desperate measures - give me a more
flexible tool (or a better solution) - I certainly don't need [more]
users hating me. ;)
