How about Russ Cox's Implementing Regular Expressions? I've not studied this at all, but I vaguely remember that Kernighan had some simple regex code for teaching.

The lua pattern matching is a subset of a regular expression parser and is a lot simpler.
Just download the lua source and open the file src/lstrlib.c. The functions for pattern matching are all grouped together. It is easy to understand and well commented. Once you grasp the general idea, you are ready to move onto PCRE sources. |

Javascript Regexp grammar is like PCRE so all the complexity is back.
Mozilla implementation is in C++: SpiderMonkey |
