You should always keep discussion on-list, that way you have less risk
of proudly announcing your new feature only to be told you have wasted
your time and you should have done it another way.  Keeping it on-list
means you are more likely to find out early before you do too much
effort. :)

Correct, its better to submit new lexers there.

Geany only supports C++ lexers, lua ones are a Scite feature AFAIK.

The speed difference is probably immaterial, what you need is a clear
easily maintained implementation for submission to Scintilla, so
making it similar to other lexers is the way to go.

Scintilla lexers do not do syntax or semantic checking, they are for
highlighting only and should be tolerant of erroneous code, since it
will exist whilst you are typing.  You would need to put the checking
code elsewhere, in a plugin maybe.
