Is there a (scintilla) lexer for reStructuredText? With a quick look at lexer names, I didn't see one.
No, the ReST filetype does not have syntax highlighting.
With that same quick look, I came across the lexer LexTxt2tags.cxx and looked at that a little--it looks like some of the stuff there is (or could be easily adaptable for my lexer for Foswiki / TWiki. What is that lexer for--is there a markup language named Txt2tags?
Oh, ok, I googled, yes there is, and I guess I'll spend a little time (a few minutes) looking at that. (For Lex: it will save me from thinking about lexing UTF-8, recursive descent parsers, switch / case statements, and if / else chains ;-)
Yes txt2tags and markdown are both lightweight markup languages, similar to wiki markup but of course annoyingly different in detail, just like wikis.
Cheers Lex
