haskell-emacs was Chris Done's first attempt at writing a new Haskell mdoe for Emacs before he merged it into haskell-mode proper; so you probably don't want to use haskell-emacs any more (it's rather old and quite probably bitrotted).

Just tried the "Quick Install" instructions at https://github.com/haskell/haskell-mode As best as I can see there is no haskell-mode after package-refresh contents There is only these when I try to do package-install [completions buffer] Click on a completion to select it. In this buffer, type RET to select the completion near point. Possible completions are: haskell-emacs haskell-emacs-base haskell-emacs-text haskell-snippets haskell-tab-indent

Update: While the install via emacs package system doesn't work, install via git does

<ot remark> Emacs package system is about as broken as a linux kernel would be if it tried to do the job of grub

Can you double check whether melpa-stable was indeed added to package-archives? (That said, I use melpa itself rather than melpa-stable to get regular snapshots rather than specific releases.) Another alternative is to use el-get to fetch it from git rather than package.el.

Changing the melpa url from http to https seems to make it work -- thanks!

[Instructions here https://github.com/haskell/haskell-mode give http]

I'll need to check more carefully

Plain http works for me. -- Gracjan

The old comint interface and new λ one -- when does which kick in

There are quite some people out there using inf-haskell (comint) and larger number of interactive-haskell-mode users.

1. Start in a foo.hs file 2. Load file 3. I get the lambda interface Instead M-x run-haskell I get old interface How do I get one uniform interface?

For easy, quick and working configuration one can use Spacemacs project. All that is needed is to switch on what they call required 'layers' and off we go. The Haskell layer is quite good, it will automatically install haskell-mode and other goodness. On Mon, 11 Apr 2016 21:50 Ivan Lazar Miljenovic wrote:

How do I get one uniform interface?

By not using run-haskell?

I load up a file in Emacs. I use C-c C-l to load the file (which starts a new project if need be), and C-c C-r to reload it if I've changed it.

I do have various customisations enabled (e.g. using structured-haskell-mode) but that's fundamentally how I interact with a ghci process (though ebal is definitely handing for setting up sandboxes and installing dependencies).

I figured that much out; viz that even if I dont need a file immediately I need to create a dummy hs file and load it.

Sorry couldn't quite parse last sentence

structured-haskell-mode aims to provide node-based editing support for Haskell code (ala paredit for Lisps); ebal is another mode that helps running cabal-install or stack. Most of the rest of my customisations is more about keybindings (and various failed experiments like code folding that I tried but no longer use); haskell-mode is fairly usable out-of-the-box. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com http://IvanMiljenovic.wordpress.com

Now from a haskell file doing C-c C-l

does nothing but tell me to study haskell-mode for more instructions  -- O well

So look up haskell mode that has:    For more information see also Info node `(haskell-mode)Getting Started'.

However the Getting started is a broken link -- "No such node or anchor"

It is (info "(haskell-mode)Interactive Haskell")

which has the key bindings needed to get it working

We accept patches for documentation, if you can help it would be appreciated. Note also our ticket: https://github.com/haskell/haskell-mode/issues/706 -- Gracjan
