hlearn-distributions depends on constrainkinds-1.1.0.0 which fails to install

Hi, I am on a mac using ghc 7.10. I am trying to install hlearn-distributions which depends on constrainkinds-1.1.0.0 which gives the following error on installation.

$ cabal install constraintkinds

HLearn-distributions has been depricated. There are no longer separate packages to install (and the latest versions are not on hackage). Instead, clone this repo. See #48 for more details.

Thanks for your response. How do I need to modify code given here https://izbicki.me/blog/functors-and-monads-for-analyzing-data.html, to get it to work with HLearn ?

[mikeizbicki]

Hmm... that code's honestly pretty out of date. I don't think there's a quick solution. Sorry.

I made some major changes to the way HLearn deals with Functors/Monads, and never bothered to update the code. I'll try to get to this as soon as I can. But I'm living abroad right now, have a poor internet connection, and a lot of other responsibilities. So it'll probably be a while before I get to this. If I haven't fixed this within a week, please remind me to look at it again.

Ok, will do

[ankitku]

Hi Mike, reminding you, as you said, to please upload some example usage of HLearn, Thanks :)

[mikeizbicki]

Thanks for the reminder! Unfortunately, I'm going to put this off a bit longer. GHC 8.0 is going to fix a lot of the warts that exist in the current code (and there's a LOT of warts!). So I'm going to wait until that happens (2-3 months?) to improve the documentation. I think that'll be a more effective use of my time, and it'll make it easier for people to actually use the library too.

Hi Mike, Thanks for your interesting page on functor/monad. Pretty hard to find examples dealing with other things than lists and trees... To explain how monad can be applied to stat distribution is very insightfull ! I know GHC 8 has only been released recently but if you still plan on updating the page on this topic, I would be very interested too !

@GodefroyClair This is still on the todo list, but I can't make any promises on a timeline.
