May I suggest

endBy anyToken semi ? -- optionally replace semi by "char ';'", if you ^^^^^^^^

Oops, I confused endBy and manyTill !! Also below. And since maybe there isn't any semicolon, I'd say manyTill anyToken (semi {- try semi, perhaps -} <|> eof)

don't want to skip whitespace

I think this is what you want --- stop at the first semicolon.

If you want to ignore just a final semicolon, you might use

endBy anyToken (optional semi >> eof),

if you want to stop at the last semicolon, whatever comes thereafter, you have a problem, you'd need long lookahead.
