18:46 < ingy> I am finding the ** syntax less and less usefu :( | |
18:46 < ingy> useful | |
18:47 < ingy> it seems I never want just a ** b | |
18:48 < ingy> I want [a ** b]? or a [ b a ]+ | |
18:50 < soh_cah_toa> ingy: you're saying the ** quantifier doesn't work inside non-capturing groups? | |
18:52 < ingy> no | |
18:53 < ingy> I'm saying that matching one or more a's separated by b's is not useful to me yet | |
18:53 < ingy> I seem to want 0 or more or 2 or more | |
18:54 < ingy> so the special ** syntax for one or more feels yagni at the moment | |
18:54 < ingy> I'm sure ** is more generalized in p6 than what I am using it for | |
18:55 < ingy> but i feel like I wasted my time implementing it in pegex | |
18:56 < soh_cah_toa> ah, ok | |
18:56 < ingy> then again, a [ b a ]* has a subtle difference than a ** b | |
18:57 < ingy> in that I had to return the result of the first as [a,[a,a,...]] | |
18:57 < ingy> but with ** I can return [a,a,a,...] | |
18:57 < ingy> which is much cleaner | |
18:59 < ingy> sigh. I'll pester moritz tomorrow |
