Not that I know. That's certainly a good idea, however I am not sure if RB can help you to highlight. RBParser stops parsing when there is an error, something you don't want to do when highlighting. Also for highlighting you typically are not able/do not want to build an AST beforehand, so RBProgramNodeVisitor is kind of useless. AFAIK in VW the RBHighlighter is implemented as a completely new parser. In Helvetia I use a PetitParser grammar that I "subclasses" to build an AST identical to the RBParser. For syntax highlighting I take the first-class Smalltalk grammar and programmatically transform it to be less strict about errors. Furthermore I attach actions that add the formatting to the parsed text as a side-effect. This is sketched in Section 3.4 of our DYLA 2010 paper: http://bergel.eu/download/Dyla2010/dyla10_submission_4.pdf.
