I've removed the Scheme part from the diff at
http://metasyntax.net/geany-erlang.diff so just the Erlang can be applied. I
don't know how Scintilla takes into account different variants of the same
syntax, but there are differences between Common Lisp and Scheme, and
amongst individual Scheme implementations, so I'll go upstream first to talk
with them about that: no point doing it one way if you just have to change
course soon afterward. Note that in the patch I didn't update the build
process for Windows since I don't use Windows and haven't any systems to
test it on. Some of the Erlang highlighting colours may need to be adjusted;
I don't use Erlang a lot yet, and I don't know what people are expected or
desiring, compared with say the angry fruit salad you can get in Emacs -
which I quite like actually but there aren't that many named styles in
Geany. :-)
