Hello all,
I have reorganized my infamous Guide To Nginx Module Development; it is now broken out into a basic Guide and a separate article called Advanced Topics. The only new material is a section on parsing with Ragel:
http://www.evanmiller.org/nginx-modules-guide-advanced.html#parsing
I use Ragel to process file lists in mod_zip, and I think other module writers could benefit immensely from Ragel. See for yourself.
Let me know if you find any bugs in either article or have any questions.
Cheers,
Evan
