Nope you should not apologize , you are not expected to read class comments before asking questions here. You will find a dedicate chapter on regex on Deep Into Pharo which you can download as free PDFs from the Pharo website. Pharo regex is very similar to other languages , AFAIK it's nothing special. I used it for language parsing from Pharo to Python syntax. But if you really want to do some complex parsing I highly recommend powerful parser like SmaCC and PettitParser , the good news is that they use syntax very similar to regex but far more readable, flexible and powerful. I used SmaCC which comes with good documentation and ton of examples , I think PettitParser is similar story.

Ah! I found the RxParser class methods for syntax and usage. I missed these previously -- my apologies.

Hi All. Nice work on Pharo!
We are starting to use the Regex pattern matching by allowing users to write "rules" using patterns. For example, our data lookup processing can include a 'Per' rule that takes a key such as 'xPerY' and returns the value of (data at: #x) / (data at: #y). Until recently, all binary-operators such as Per were performed with a simple string matches. But in order to generalize, we are moving regex patterns.
Can someone tell me where the language-spec is for Regex-Core that is included in Pharo? Is this in the style of sed, awk, or ... ? If possible, how do I indicated that I want several sub-string replacement sections?
Thanks in advance. -Cam
