haskell-mode

If I made it sound like there's something like IntelliSense today, apologies! We've got <https://github.com/haskell/haskell-mode/blob/master/haskell-...>, but it's type-a-command-and-do-a-search: it's not linked in with completion directly in the setups I've seen. (In practice, I'm usually starting from a slightly different place: I know I want a Frob and I've got a This and a That, so I do :hoogle This -> That -> Frob and get some options. The thought-process is working backwards from the goal more than forwards from one key object in focus. A different way of working, but I'm not convinced it's less effective.) My point though was that it's an engineering issue, not a fundamental language limitation. ie not a reason all future languages should shun haskell features. The building blocks to do better at completion than haskell curently do

Most serious Haskell users are most likely using a REPL and when doing this it's trivial to get and think about type information even while checking other stuff. It's also obviously part of the thought process while developing anyway, so I don't see the same value in this as you do. There's a cost to having a full IDE anyway and it's more sensible to get the features you do want (auto-completion, etc.) from plugins and then not using a IDE. Even if you want these things, there are better ways to go about this instead of making a whole gargantuan interface to get a couple of features. I'm not usually one to tell people what they should be working on, but time could be spent on this instead: https://github.com/haskell/haskell-mode/wiki (See also this for how to get in-source error information and type checking, if needed: https://wiki.haske

When you're writing Haskell in emacs (like you should be), you enable haskell-font-lock-symbols in haskell-mode, and it displays the lambda as it should be (plus a bunch of other symbol corrections for ::, ->, =>, (), ||, &&, etc.) Full list here: https://github.com/haskell/haskell-mode/blob/master/haskell-...

> I grew frustrated trying to edit Haskell in Emacs; there are a bunch of half-baked modes out there. What's wrong with the normal haskell-mode? https://github.com/haskell/haskell-mode (interestingly another commentator here claims that Emacs' Haskell indentation is superior to VIM's https://news.ycombinator.com/item?id=7111521) > It's not great at doing version control [...] Have you tried magit? It's probably the best version control support I've ever seen in an editor.
