#16 Can't compile certain pattern

[Anonymous]

Hi,

Just testing out jregex again, and have found that it
can't compile the following pattern:

{(\d+):(([^}](?!-}))*)

The Exception is "malformed quantifier"

This pattern works correct in OROMatcher, GNURegex, and
standard Perl5.

Any ideas?

Hi!
Just escaping the curly brace makes the thing work fine:
\{(\d+):(([^}](?!-}))*)
Currently I'd suggest you take it as a feature (which if fact it is)
rather than a bug. It stems from my own idiosyncrasy - I don't
especially like such frivolous bits in the perlre syntax. Should it be
fixed?

P.S. The test case from the oro list also makes no problem.

Well, it's not strict perl5 regex, so strictly it goes
against your feature claim of "Perl5.6 regex" :)

I did try with the \{ just after I sent this bug report, so
I can confirm that too.

In terms of fixing the "issue" I would think it would be
better to do so, an easy check to see if the character after
{ is a digit, and if not, treat { lie [{] or \{

Regarding the P.S: I had a production bug report for some of
our software, and the root cause was ORO. I have
recommended putting JRegex in place of ORO. [JRegex seems
to run fine on a 48k stack :) ] , although I had to do a bit
of work getting our software to work functionally the same
as GNURegex and ORO.

Quite impressive with your stability and speed of JRegex!
Hopefully we won't see any production problems to cause me
to come running. :)
