Hi,

Unfortunately the Scintilla editing component (www.scintilla.org) we
use does not support embedded languages other than rudimentary support
for a few scripting languages in HTML.

This is not done by using a different lexer, but written into the HTML lexer.

To change this you need to change Scintilla (written in C++) to
provide this capability.  Advice on doing that is beyond the scope of
the Geany ML.

Lex
