It did.
I've been told I can use regex.h for powering the regular expression
searches in my app. I'm never actually touched pure C code (is regex.h
C?),
Yup.
so I've really got no idea how to implement it in a Cocoa based
application...
I understand all the theory work, but I'm still at a lost as to how to
use these functions, for example, in Obj-C, I would do something like:
NSString *hello = [regex parseString:@"hello"
withExpression:expression];
Nope. C functions use C strings. There are no ObjC calls involved here,
just function calls.
See here for a pure-C example:
http://publibn.boulder.ibm.com/doc_link/en_US/a_doc_lib/aixprggd/
genprogc/internationalized_reg_expression_subr.htm
and remember that + (NSString) stringWithCString; and - (NSString)
cString; are your friends.
