That is a seriously good framework, and the documentation is great
too.
My only issue with regexkit is that it uses PCRE instead of ICU.
PCRE has to be compiled into the library, making it larger (whereas
ICU is already built into the OS.)
PCRE is also, last I checked, less I18N-savvy than ICU. This has given
me grief in the past; I used PRCE-based regex code in a project 3
years ago, and as soon as the Japanese and Korean testers started
working with it, they found that the app's text searching didn't work
correctly for them. (In a nutshell, PCRE's notion of "alphabetic
characters" and "word breaks" only works for Roman writing systems.)
Unfortunately I don't know of a comparable Cocoa regex library that
uses ICU. (NSPredicate does, but its support for regexes is very
limited, as already discussed in this thread.)
