Intero for Emacs: complete interactive development program for Haskell

I saw this notice on Reddit early yesterday morning and ended up using Intero for most of the day. Love it! There are a lot of improvements over and above the Emacs Haskell mode. I really like how fast it is to control-c-l and be put n the correct module and be running in seconds. I also like the realtime syntax error hints, type information, etc.

There should be a warning that on first start of intero-mode, this will initiate a rather long stack operation, which I suppose is extra long if you hadn't used stack before. Also, it seems to insist on a stack'ised project. But I suppose one could say that should be obvious. I use cabal because stack misses some features and is a little weird and use stack when I have to. And even though I have intero installed and in $PATH, when opening an actual project with a stack file, it start building intero. Weird automatism.

This looks great! My only complaint is that sometimes I do want to work on a quick script outside of a stack environment, and this seems like an all-or-nothing proposition. (I use haskell for pandoc filters quite a bit, for example, and setting up stack for that seems like overkill.) I'm sure a bit of elisp could make it fall back to haskell mode if it can't find a local .stack dir.

Haskell changed my life. Then Intero did it again.

I've been waiting for this release before finally trying to switch from Vim (MacVim) to Spacemacs. Anybody have any tips for somebody who's never really used Emacs?

I wish I could get a similar utility for Python and Javascript as this seems to show off some cool FP auto complete.<p>I&#x27;m basically looking for a way to remove my dependency on my 5-7 IDEs and I don&#x27;t know how. I wish someone could show me a very good, simple, alternative to all of them. I work in C, Java, JavaScript, Python, PHP, and C# and I&#x27;d like to be able to use a single IDE solution for all of them. Sadly I cant find anything with good auto completion and nice features (like things offered by Eclipse).<p>This has some really promising features, I&#x27;ve got to say I&#x27;m amazed.

Looks like I&#x27;ve got a choice to make (all on NixOS):<p>+ Stick with NeoVim and hope one of the Intero ports to that editor takes off (as I understand it there are a couple right now)<p>+ Switch to Emacs+Evil+Intero. I&#x27;ve never used Emacs before (even with Evil) so it would be a little work.<p>If someone more up-to-date on the situation has advice that would be awesome:)

It didn&#x27;t &quot;just work (TM)&quot; for me, I had to customize the intero-package-version in my .emacs when using it with a project with the latest stack-nightly, to bump it up to &quot;0.1.16&quot;.<p>But other than that, wow! I was already very happy whenever I could get ghc-mod and haskell-mode to work, but this takes the responsiveness to a whole different level.

Very nice! But is there currently no way to get any information about third party code other than the type signature (C-c C-t or C-C C-i)? Ideally I&#x27;d like to be able to both navigate to the source code and see the documentation.<p>It might also be good to mention that you need to apt-get install libcurses5-dev for the haskell code to build.

Wonderful package. Works nicely on Windows too [1].<p><pre><code> [1]: https:&#x2F;&#x2F;ianchanning.wordpress.com&#x2F;2016&#x2F;08&#x2F;11&#x2F;installing-haskell-emacs-on-windows&#x2F;</code></pre>

I rather use Leksah (<a href="http:&#x2F;&#x2F;leksah.org&#x2F;" rel="nofollow">http:&#x2F;&#x2F;leksah.org&#x2F;</a>), but it is nice to see other options available.
