State of package? #8

Closed 3noch closed 7 years ago

3noch commented 7 years ago

Since this package shares so much in common with async I'd appreciate a README that helps me (and others) place this package in the grand scheme of the Haskell ecosystem. async is actively maintained but async-pool has had very little action in years.

Care to elaborate?

jwiegley commented 7 years ago

I haven't been using async-pool as much in active code recently, so I haven't paid much to attention to whether there have been changes in async that should be carried over.

It simply extends the API of async to work in terms of working pools, and this is all. Other than that one change, it aims to retain the look and feel of using async.

@jwiegley Thank you for the quick response! The fact that async-pool completely re-exports async means it should probably get a new release along with async every time it updates. That's obviously a lot of work...but that's why I assumed this package was falling out of date. However, it looks like the version bounds on async aren't even specified which means this package has a very interesting version policy. ;) How would you feel about not re-exporting async and just exporting your additions? I think that would make its place in the ecosystem less ambiguous.

Also, do you have any thoughts on the Task monad as it relates to the Monad and Applicative laws?

jwiegley commented 7 years ago

@3noch That sounds like a good plan. Since I change the type of many of async's methods, I should probably just add a suffix to my versions, so that both library can be used easily in combination.

I'm not as sure about the Monad and Applicative laws for Task, since I haven't done the proof work on those. Have you run into any issues?

3noch commented 7 years ago

@jwiegley That's a good idea. Either that or just relying on qualified imports.

No I haven't had any issues. I just know that having ap /= (<*>) is fishy when it comes to the laws (due to differing effects).
