Now I am trying to use the Scintilla again. I tried to write a Scintilla lexer for Ruby today but gave up as it was more complex than I thought. The complex bits are arbitrary characters used for quoting and here documents both of which require quite a bit of maintained state which is hard within the incremental lexing framework of Scintilla. However, Ruby is lexically similar to but simpler than Perl. Unless there is are some more complex lexical features I've missed. So the best place to start is with the subset Perl lexer which has to deal with both extended quoting mechanisms. The current Perl lexer only handles a subset of Perl but is still quite large. I think its quite reasonable to first develop a subset Ruby lexer and then gradually add features. If someone develops a Ruby lexer, I'd like to include it in the Scintilla distribution so it could be used in SciTE and any other editors that use Scintilla.
