Hey, almost perfect, found is_code_style() which is exactly what I need,
thanks a lot!

True, and same for opening ones. Should be relatively easy to fix
though, even if it's perhaps not a change trivial enough to be in 0.19.

It doesn't seems that simple since if I replace pos by pos - 1, the
brace matching indentation breaks…

You mean a complete setting like the indent mode (with different levels,
etc) or simply a kinda boolean setting like "auto-indent parentheses"?
Maybe a complex setting might be interesting to allow not only
alignment, but also Geany-style of extra-indentation that isn't
alignment and even other if somebody needs it.
Ah, and there is another thing I would have to improve bracket matching
indentation when the opening one is indented because of an alignment:
backward parentheses matching after bracket matching. This would fix
indentation of something like:
if (a &&
/* code */
which currently result to:
if (a &&
/* code */
which is obviously wrong here. I mean that the bracket is first matched,
and then if there is a non-balanced parenthesis, it is matched to
finally get the indentation. Well, of course it's probably not enough in
some cases an/or languages, but it would probably fix the majority of
Not sure if it should be completely related to parentheses
auto-indentation and/or matching, or if it should be part of a sort of
"intelligent detection of alignment vs. indentation".
Anyway, I join an updated patch that seems to work very well (at least
for me), thanks to is_code_style()! It still misses settings, and I
would like to know your thoughts about what should depend on which
setting (there's FIXME in the patch for them); and even how you'd like
to see it in the preference dialogue.
