Re: [Boost-users] [regex] Boost.Regex + ICU vs. standalone ICU

John Maddock writes:

To a large extend all regex engines are created remarkably equal.

Looks like ICU hasn't caught up with some of Perl-5.10's additions yet (recursive expressions for example).

The other advantage of Boost.Regex is that being iterator based you can search text in non-contiguous storage.

Those were the only two that jumped out at me from a quick look at ICU.

HTH, John.

Thanks, it does :). Indeed, it doesn't sound like there's a ton of difference. I actually didn't know that Boost.Regex supported recursive regexen. Would you mind pointing me to the documentation for it, and/or what the syntax looks like? Thanks again.
