Thanks all,

in the end I've used PetitParser and I was really surprised and happy how easy and far I've got with it.

TBH using regular expressions in Pharo feels extremely uncomfortable to me compared to Perl or Ruby, but maybe that was design decision by the author to not be too hacky.

So at least to me PetitParser feels like a more practical regex library than Regex itself.

I would start with streams and regular expressions. If that's not
powerful enough I would use PetitParser. If that's not fast enough, I
would try SmaCC and compare speed.
