 Spell-checking gtk-docs

Motivated by Andrew Cowie's Spell-checking Java source code, I decided to give it a try on Pango. So I ended up spell-checking Pango's and cairo's documentation, fixing more than 100 typos in Pango's, and some 40 in cairo. Not bad for a three hour work.

Unlike Andrew, I didn't directly spell-check source code. What would have been too intrusive. Instead, I extracted gtk-doc blocks (and other block comments) out of source code:

$ grep '^[ /][*]' *.c > docs

Then spell-checked docs, and finally diffed docs.bak and docs and went over the changes, applying them to source code manually. For the sgml template files it was easier, just spell-checked the files directly.

The idea is to use "Add to list" as few times as possible. For example, Pango API has lots of parameter names "ink_rect" and "logical_rect". But instead of adding "rect" to the spell-check dictionary, I preferred "Ignor"ing everytime it nagged about the "rect" in "ink_rect", but it did help catch a couple places that "rect" was used in a sentence. And I replaced those with "rectangle".

Have you considered running gnu style and diction on the docs?

It is something I've been meaning to do for years now. Would be great if we could get all the documentation to a fully quantifyable reading level.
 
vim7 can check spelling of comments and strings on the fly.
