Q: thoughts on takeSome and takeMany about purescript-parsing

[safareli]

Or maybe instead of defer of the f, LazyList's Internal Lazy should be used somehow?

How does this relate to replicateA?

[safareli]

It's somewhat related but it has no some/many semantics. like takeMeny will try parser n times, but if at some it fails, it will return staff it has already collected.

[safareli]

takeMany n will try parser up to n times and result could possibly contain zero elements
takeSome n will try parser up to n times and result must contain at least one success

[safareli]

I think we should define takeSome and takeMany on List and Array as there is no other thing with semantics described above. the only way to fulfill the need I had, was to implement this functions as no other existing functions can help. I think it could be useful to others too

[safareli]

what you think on takeSome and takeMany ? do you want to see PR for List/Array?

[paf31]

Seems like this be implemented using many and guard.

[safareli]

Hm, If you use guard them you might need Monad instance, even if monad instance I can't think of such implementation :/

replicateA repeats a pattern exactly n times. Regular expressions have first-class quantifier syntax for repeating a pattern at least n or a most m times. It's a common pattern. Would be nice to have API support for this, or at least documentation which explains how to accomplish it.
