OK, so I was happily just using the oromatcher Perl5Compiler() routines to handle python style regular expressions in my java code. Basically the regular expressions get passed from the jython script through to a java function of mine and I wanted to handle them in a python compatible way. It turns out that I wasn't completely correct.
I got code that actually worked pretty well until I started passing expressions such as this to it:
"(source filename|Name of).*\?(?i)"
The gotcha is the (?i) bit at the end, this generates a mismatched parenthesis error.
Now after a lot of delving I've discovered that jython actually uses a completely different regular expression library - the one in the sre module. My question is, since this is all python code, is there any way that I can just call out to this from java? It appears to me that by moving over to a python implementation here I can't use the same stuff - so far I've found one incompatibility between the two implementations, and I'm concerned that I'll run into others.
Am I stuck with pre-processing the regular expressions and handling the (?i) construct myself - I can't believe that's all that there is to it.
Any other alternatives?
As an aside, why the switch to sre? Faster? Better Python compatibility?
