Why not just go with anchorHead and anchorTail or similar? And a capture could simply be
Thanks for your inputs Brandon. I've updated the code with anchors. Still trying to get a hold of captures.
What are you finding difficult about them? Backreferences? Given that this is Haskell, I'd look for ways to "tie the knot", although in terms of usability it's probably best to maintain a list of captures where the knot is actually tied between a capture regex component and its captures list entry, with backreferences either also tying the knot with the captures list or containing an offset in that list. Practical usage: you need to be able to access the strings matched by captures from "outside", so you want an independent structure for those captures rather than having to gmap the regex tree to get the captured strings. -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
