Highlight certain parts in comments [message #1040317]

Hey,

I was wondering whether it is possible to highlight certain parts e.g. links starting with @file in a comment. For example:

//this is a comment and then I have a link @file://a/link/to.somewhere and now the comment continues

I tried something like

terminal LINK:
	'@file://' -> ' '
;

terminal SL_COMMENT:
	';' (LINK | !( '@' | '\n' | '\r' ) )* ('\r'? '\n')?
;

but there is no node created for the LINK in SL_COMMENT. Is this possible at all?

Thanks in advance,
Maximilian

What about using a datatype rule?
or reparse the comment yourself

At the moment I do parse the comments myself. I was just wondering whether there was a nice 'built-in' solution for that. As the text to be highlighted is in comments (--> they have to be hidden) I need a terminal rule.

I do extensive comment formatting and coloring of comment text in
cloudsmith / geppetto @ github if you are interested in looking at code.

Geppetto has a markdown/rdoc type comment processor (handles
bold, italic, headers, bulleted lists, preformatted etc. etc.)
There is also configurable styling for the comment formatting.
