Conditional Regular Expressions in ORO

[Ion Freeman]

Hello!
I'm trying to match 'b' or 'abc' -- so, a simple '(a)?b(?(1)c)' should
do it. Now, the java.util.regex classes don't do it, so I'm trying
ORO. However, ORO gives me

Sequence (?(...) not recognized

So... does anybody know if ORO does not support this as well? Is there
a Java library out there that does?

This is funny, because I'm just playing around with the little Java
regex tester I built.

Match b or abc: b|abc

OK, that was easy. How about: a?bc?

Both work for me. Are you sure you checked this correctly? Because
your pattern gives me an exception. How about posting an SSCCE?

I'm trying to match 'b' or 'abc'

b|abc

'(a)?b(?(1)c)' should do it

Which language is this supposed to be written in?

What's wrong with "(b|abc)" ?
