Wisent Parser for font-lock MATCHERS

[Perry Smith]

My apologies if this questions is not appropriate for this list.

Strings in ruby are very complex.  They require a PDA and not just a  
DFA.  I'm mid-way through writing a function to properly recognize a  
ruby string but then paused to consider perhaps I should use wisent  
instead.  I've not used wisent before.  If I'm going down a blind  
alley, please let me know.  Or if there are samples of other wisent  
parser based font-lock matches, that would be of interest to me too.

Specifically, my thoughts are to have a parser (or perhaps parsers) to  
use as the MATCHER function in the various font-lock lists such as  
font-lock-syntactic-keywords and font-lock-keywords.  My fear is that  
the wisent parser is not going to let me hook in like I need to in  
order to properly create a matcher function.

As background, I know about ruby-mode and cedet, semantic.  There is a  
wisent attempt at a Ruby parser but it does not do strings properly  
either.

Thank you,
Perry Smith
