[plt-scheme] Re: What to augment, how to highlight ?

Okay, thanks ;)

However, i always have a prob with string and comment :

[str (concatenation "\"" (repetition 0 +inf.0 (union digit letter
punctuation symbol whitespace)) "\"")]
[comment (concatenation "#" (repetition 0 +inf.0 (union digit letter
punctuation symbol whitespace "é" "è" "ù" "à" "#")) new-line)]

(str
   (values lexeme 'constant lexeme (position-offset start-pos)
(position-offset end-pos)))

(comment
   (values lexeme 'comment lexeme (position-offset start-pos)
(position-offset end-pos)))

The expreg seem to be correct, but the colorer don't function all the
time.
I don't know why ?

Thanks,

Laurent
