Hey everybody. I do quite a bit in of work in text formatting languages like groff and nroff, and there are some simple organizational tasks that I think should be fairly easy to automate (i.e. - complex page headers/footers, table of contents, etc.), and so for the past month or so I've been toying with the idea of writing a front end for groff in perl. Until about a year ago my primary platform was Pascal, and having written a few lexical scanners in that language I am very familiar (and incidentally quite dependent on) the use of the pos() function. This function returns the index of a character in a string, and is useful for determining the location of whitespace and tokens. Although I have considered doing this in lex or yacc, I think it would be a shot in the arm for my perl skills to sit down and write a good 'ol lexical scanner in this language. I'm about 90% sure that it's just some library function I'm missing, but it would be helpful if someone could point me in the right direction. Thanks.
