stack

Luckily, Stack [1] allays a lot of the reproducible build hell that Cabal sometimes provides. I would highly recommend trying Stack out before deciding that the Haskell package management system is a dealbreaker for you. More and more open source projects are using it - and if they aren't, perhaps that could make a good first contribution to a larger project (if you're having build trouble with vanilla Cabal, others probably are as well).

I'm not sure Haskell's a freight train anywhere. :) It's an all stations passenger train to deeper understanding. More generally, learning Haskell (and to a great extent any programming language) is about a different way of doing things. Deep Learning is a thing to do. (It can also be a way of doing other things, but my point is that they're at different levels.) With that said, your time is limited. Studying Haskell, Deep Learning or Statistics (an option that is criminally underrated) is a choice you have to make, and Haskell isn't necessarily the best use of your time. If you feel like dipping your toe in the water, though a) install stack https://github.com/commercialhaskell/stack b) try doing this course (http://www.seas.upenn.edu/~cis194/spring13/lectures.html) and _do the homework_. If you find you're enjoying it, you'll have your

Haskell has a pretty cool new dependency management tool called stack (https://github.com/commercialhaskell/stack). It's based on the curated package server https://stackage.org which server sets of packages that are tested for compatibility.

You should give Haskell another shot. Since last you tried, this happened: https://github.com/commercialhaskell/stack. In fact using stack is the recommended installation method for HaskellR, rather than using the cabal-install command.

I've heard the GHC on Windows situation improved a lot with: https://github.com/fpco/minghc Myself I don't use Windows, so verify the claims. But might be worth to give it another try. Also Stack[1] has made it lots easier to get rolling on that platform. 1: https://github.com/commercialhaskell/stack

> Concerning Haskel it still lacks some pragmatism to solve some pratical problems such as install and cabal hell. I'd argue stack pretty much solves those: https://github.com/commercialhaskell/stack

> Why are there so very few programs written in say, haskell, that you actually want to use? I think a big part of it was struggling with cabal hell. I know that quite a bit of web development and API stuff is happening with Haskell since I've gotten paid to do some for multiple clients (some requesting Haskell). I think that with the release of stack[0] (and it eventually being merged into the Haskell platform IIRC) many application developers will start to pick up Haskell and create those types of programs. Not open source, but an application created in Haskell was bump[1]. 0: https://github.com/commercialhaskell/stack 1: https://www.fpcomplete.com/wp-content/uploads/Bump-case-stud...

No problem. You can also find my email in my profile. Feel free to email me with specific questions. I'm interested in helping people see how Haskell applies or finding cases where it doesn't apply to their real world use cases. I also have a few semi-useful things on my blog currently so I'll go ahead and put that in my profile as well. EDIT: Additionally, if you experiment with Haskell be sure to use Stack[0] instead of cabal to avoid potential headaches. The Stack wiki[1] was a useful but easily overlooked resource for me as well. 0: https://github.com/commercialhaskell/stack 1: https://github.com/commercialhaskell/stack/wiki

We should see a lot more action from the frontend Haskell camp once GHC 7.10.2 drops and stack begins to support building ghcjs. The next 12 months will be an exciting time. Some discussion about it here: https://github.com/commercialhaskell/stack/issues/337

Use Stack instead of installing Haskell platform, your distro's Haskell package: https://github.com/commercialhaskell/stack After installing stack and putting ~/.local/bin on your path here is how I start a project: cabal init < answer questions > stack init The above will be replaced by `stack new` in the future I think, but `stack new` doesn't work for what I'm doing atm. Learning: https://github.com/bitemyapp/learnhaskell http://haskellbook.com/ After those, just start writing crappy Haskell code to solve real tasks you need/want solved. The most important thing is to focus on creating working software with the language, since that's the fastest way to learn. After you've done this a couple times start reading source code of libraries which solve the same problems you've implemented and see how they are different. This may

For a recent project I did: cabal init stack init stack build Then I wanted a newer version of persistent, so I opened up my stack.yaml file and added persistent 2.2 to the extra-deps section: extra-deps: - persistent-2.2 Then I was wondering how to make emacs haskell-mode work with it, and I saw this[0] in the stack repo: ((haskell-mode . ((haskell-indent-spaces . 4) (hindent-style . "johan-tibell") (haskell-process-type . ghci) (haskell-process-path-ghci . "stack") (haskell-process-args-ghci . ("ghci"))))) Now everything is working flawlessly and very fast. As a bonus Haskell-mode works correctly for projects I haven't moved to/tested with stack yet. 0: https://github.com/commercialhaskell/stack/blob/master/.dir-...

This is false, see the `stack solver` and `stack init --solver` commands. Currently it's using cabal's dependency solver under the surface, but there is work in progress (by multiple parties) to implement a new SAT-based solver, see: https://github.com/commercialhaskell/stack/issues/116

> The haskellverse is jammed packed with popular packages that won't build and run properly on your platform This tool is aimed at fixing that, ironically the GP used cabal in an attempt to install a tool fixing cabals problems. > Nothing quite works except for small toy projects and Haskell +systems whizzes who can dig into native platform arcana. Not true. Did you have a bad experience building a Haskell package for a specific platform in the past? Stack might let you install it all seamlessly, you should give it a try :) I recommend installing one of their binaries though: https://github.com/commercialhaskell/stack/wiki/Downloads
