How to ignore comments in the LaTeX file with ispell (within Emacs if possible)

Question

I'm writing a text with Latex in English but written my comments in Finnish. When I'm running the spell checking with ispell, I got to run through all the comments. Is there a handy way to skip the comments with the ispell? If that could be done with emacs, that would be double handy =)

One way would be to run the ispell within console and process the input with sed, for example, but I'd like to have my changes straight on the file...

Answer 1

(setq ispell-check-comments nil)

Answer 2

You'd have to dig in the code a bit, but when you spell-check a file, it's running the detex tool to strip out the TeX code. You should be able to modify the pipeline to have a sed or perl script strip the comment lines.

I kind of vaguely think AuC-TeX makes this configurable, but 30 seconds looking didn't reveal it.

Answer 3

Adding a modern answer to this old question, because I also had the problem:
Just use aspell, which does this out of the box.
