intersperse

[jfilip]

Very useful functions for combining arrays of monoids (like strings)

[garyb]

As string aren't arrays in purescript they actually currently have their own intercalate equivalent already joinWith (in purescript-strings).

[jfilip]

Hmm, ok, not as generic as a monoid-intercalate, but good enough for what I'm doing now, thanks!

[joneshf]

These would still be nice functions to have, do they belong here, or can they be put somewhere more general?

[garyb]

I guess they'd be like intercalate :: forall a. (Monoid a) => a -> [a] -> a, and monoid already depends on arrays, so putting it there would make sense.

👍 for adding this to monoids.

[joneshf]

I wonder if there's a fold for this.

[garyb]

I'm working on that now actually.

I think intersperse should stay in foldable-traversable, but I also think a monomorphic Array.intercalate :: forall a. a -> Array a -> Array a would be a good thing to add here. Shall we reopen this?

[hdgarrood]

Agh, got them the wrong way around.

[joneshf]

Given that we all seem to always get these names wrong, it seems like they could have better names.

In any case, I'm all for a forall a. a -> Array a -> Array a in here.
