Haskell IDE Using Atom and Stack

Due to the strength of its type system, Haskell lends itself to a great IDE experience. However, that IDE experience has not been as easy to come by for Haskell as it has been for other languages.

Here's how to setup a decent IDE experience for Haskell using Atom and the new stack build tool.

1. Get Atom.
2. Get stack on your PATH. (As of version 0.1.5.0, the 32-bit build is more stable than the 64-bit build.)
3. Install dependencies via stack install ghc-mod cabal-helper hlint stylish-haskell
4. The command output will tell you it is installing binaries to a particular folder. Add this path to your PATH or copy the files to somewhere else on your PATH.
5. Install the ide-haskell Atom package and its dependency packages. At the time of writing, the dependency packages are:
   • haskell-ghc-mod
   • language-haskell
   • autocomplete-haskell
   • ide-haskell-cabal
