(Kozz) RE: RE: regexp for adding commas to a number

[Kozz]

Thanks for the insight. I'm ignorant of the secrets of lookahead, lookbehind, inner repetitions, and all the other associated voodoo with things like this, so while this regex certainly works, the breakdown of what it all means is a mystery to me. Would "Mastering Regular Expressions" be a good teacher for this sort of thing?

Thanks, merlyn (++), and everybody else for their help and insight.

The currently available Mastering Regular Expressions doesn't cover any of the really cool Perl 5 regex stuff. Jeffrey Friedl is in the process of rewriting the book for a second edition, and has been working with the Perl developers to uncover inconsistencies in the implementation (what normal people would call "bugs" {grin}) and gaps in the documentation.

Don't hold your breath though. I know this effort will probably take one to two years of nights and weekends. "Been there Done that" x $n
