Comment removal is usually done as part of lexing, so during lexing

line numbering (and have a split between lexing and parsing) usually
you would annotate lexemes with their source position.

Thanks! And sorry for late reply.
The answer for me means that I should use common method of separate lexem / parser instead of using parsec with Char Parser.

I will do that anyway since it will probably improve the performance of the parser.

One more question:
Do you know If there is a lexing technology which can inter work with Parsec based Parser ?
With inter work I mean that line number information is preserved across lexing/parsing.
