  • Anyone know the best way to use haskell for arch linux?

    You can use ghcid. It compiles the code, and shows if there are any errors as you save your file. Have two terminals. One for editing your file...other one with ghcid ($ ghcid path/to/filename.hs). Right click on the ghcid terminal and click `always on top`. That way, It will be always visible as you are typing and saving code.
  • Static-ls - a low memory Haskell language server based on hiedb and hiefiles

    With a combination of ghcid, an hiedb filewatcher and the -fdefer-type-errors flag you can get pretty solid IDE behavior. Currently only ghc 9.4.4 is supported but happy to personally help people set this up if interested!
  • What's the best Editor+Tests experience we can get with Haskell?
    1 project | /r/haskell | 21 Sep 2022
    With an editor integration, you could rig it up to where you could right-click on a Spec, choose "Run spec" from a context menu, and have your editor add that comment to and save dev.hs. Another editor integration could read and parse the contents of ghcid.txt. We have this already for the compiler output, but it doesn't yet parse the test output. But sans an editor integration, you will still see the test output in the console where Ghcid is running.
  • What's the best way to use a REPL for TDD?

    Sounds like you want ghcid. You can use it run tests on a successful build, and it will watch files in your project and quick-rebuild when there are changes. There shouldn't be any need to modify your Cabal files or test dependencies.

    In addition, for Haskell, I usually have ghcid running, which likewise re-runs on every file change, but gives faster feedback about any type errors than the full compiler, and also is configured to evaluate

  • Most braindead easy end to end haskell workflow?
    4 projects | /r/haskell | 23 Jul 2021
    VS Code + Haskell extension is usually best, but ghcid is an alternative which is much simpler, easier to set up, less pretty and powerful but still pretty easy and effective to use. Here's a workflow:
  • How to cabal?
    1 project | /r/haskellquestions | 4 Apr 2021
    In general, though, I recommend just looking at the cabal files for various libraries and executables. Something like ghcid is good, since it contains a library, an executable, and a test suite.
  • Fast way to run Haskell script from nvim?

    you should also checkout the ghci vim plugin https://github.com/ndmitchell/ghcid/tree/master/plugins/nvim
