Questions about Development Environments in Emacs

Questions about Development Environments in Emacs

[brettg]

Hi all.

I have some questions about the availability and usability of specific 
development environments in Emacs on GuixSD. I know that GuixSD is not 
"production ready" but with 1.0 supposedly approaching soon, I am still 
using Virtual Machines to Parabola GNU/Linux-libre for some of my 
development work.

On this note, what is everybody doing on GuixSD for support for 
languages like Clojure and Haskell?

Clojure has the wonderful CIDER emacs-mode, which I know is packaged, 
but it is seemingly without use without a proper nREPL like Leiningen. 
How are other people getting intellisense and other slime-like features 
from CIDER without lein's nREPL?

Similarly, Haskell is in a similar position with Intero not being 
available. Are people developing for Haskell on GuixSD yet? What are 
they using?

Thank you for the support, and keep on!

I'm facing a similar issue at the moment.  Does anyone have a good
answer to develop Haskell or Clojure with Emacs on Guix?

Cheers!

I write a fair bit of Haskell. I find that I like to use cabal-install to develop, then make a .scm file for the guix package separately.

haskell-mode works well in this workflow. There are a few tweaks to make, to get the most out of it.  cabal complains if GHC_PACKAGE_PATH is set, so I use the Elisp variable haskell-process-wrapper-function to add "env -u GHC_PACKAGE_PATH" prior to the cabal commands.

The only other complaint I have is that flycheck-haskell only supports stack. haskell-mode has excellent error reporting, though.  So I’ve never had a major complaint.

We could probably package stack. It is widely used in industry so it could make guix more usable. That would also start intero support.  I am not sure if intero is maintained anymore, though. If they don’t find a maintainer I am not sure it will make it into guix.

Happy hacking!

Thanks for sharing, John!

And any one using Clojure?

Hi Pierre,

You are correct that Clojure development via CIDER is dependent upon
having at least one of the three Clojure build tools installed and on
your PATH. These are your choices (in order of age):

- lein    https://leiningen.org/
- boot    https://boot-clj.com/
- clojure https://clojure.org/guides/getting_started

All three are simply shell scripts that download their respective JARs
into $HOME/.lein, $HOME/.boot, $HOME/.clojure, and/or
$HOME/.m2/repository.

For lein and boot, I just manually install them into a scripts directory
in my $HOME directory and add that to my $PATH in my ~/.bashrc. For
clojure, I pass the installdir option to its installation script to put
all of its files in $HOME/local (which I add to my PATH instead of using
the global /usr/local).

Creating a Guix package for any of these three tools shouldn't be all
that difficult, but I have unfortunately not yet taken the time to put
them together. If someone does create them though (particularly one for
`clojure`), I would be quite happy indeed.

Happy hacking,
  Gary
