On what editor setup you get this kind of functionality with Haskell? I mean the auto-insert of the inferred types.

  I’ve been out of the game for a number of years but I used something called ghc-mod [1] with its associated vim plugin [2] to get this functionality. Moving forward, it seems that all of the effort has moved over to Haskell IDE Engine [3]. It looks like this exact feature hasn’t been brought over yet but it is planned. In the mean time you could still use ghc-mod though.

    Thanks for the tip! Haskell IDE engine is exactly what I've been using til now and would've been very pleased to find out it had such a convenient feature. Ghcide is on my list to try next as it's gotten a lot of attention lately.

      Yes, it already has a code command to automatically add top level type annotations. The caveat I that it can only work if you add -Wall to your compilations flags.

  It seems that "ghcide" can do this: https://twitter.com/chris__martin/status/1218331415869190144 https://twitter.com/chris__martin/status/1218331415869190144 https://github.com/digital-asset/ghcide https://github.com/digital-asset/ghcide

    Template Haskell not working on ghcide has sadly been holding me back with it. I've heard great things about it otherwise
    • jose_zap 7y ago
      You can use HIE. It supports template Haskell

  Recent ghcide can do it now as well as https://github.com/mpickering/apply-refact https://github.com/mpickering/apply-refact for hlint
