This would probably make a good plugin.
It should be possible, at least for languages who's lexer supports
folding and where folding is roughly equivalent to scope. Maybe
something like:
* find the current line's fold level
* walk backwards each line until the fold level decreases
- store that line's start position
* walk forwards each line until the fold level decreases
- store that line's end position
* for each character/cell in between start and end, change style
Indeed, most languages are folded with respect to scope. I hadn’t
thought of that because I don’t tend to use folds much. This is more or
less the kind of simple algorithm I had in mind, but more general than
the concrete brackets/parens example. Good idea.
You could probably also do something similar but calculate the XY pixel
coordinates of a box around the scope and draw an overlay window at
that
box's size and position, allowing input to go through to the Scintilla
widget underneath (similar effect to XCode's scope highlighting). This
is kind of a similar effect as my "blackout" experiment except around
the scope box instead of the whole editor widget:

Interesting idea. I think I’d do it the simpler and less radical way
though.
Sounds like writing a little plugin is going on my to-do list then.
Just for fun I made a little experiment doing what I was talking about:

Nice! Could scope detection potentially also be used to add local
variables to autocompletion?
I'm not sure but I doubt it, it's just using Scintilla fold points as
described in the simple algorithm above (roughly).
PS: The video didn't play in VLC (stuck on first frame) but did with
ffplay.
Dunno, plays here locally in VLC. IIRC it's using H.264 in an AVI container.
Cheers,
