I’ve wanted to give Spacemacs another try for Haskell development. In particular, I wanted it to work with
I like to use Mitsuharu Yamamoto’s emacs-mac, rather than Aquamacs or emacsformacosx.
$ brew tap railwaycat/emacsmacport $ brew cask install emacs-mac
haskell layer in Spacemacs requires a few dependencies. I installed them with Stack.
$ stack install hlint hasktags hoogle ghc-mod intero $ stack --resolver nightly-2017-08-12 install apply-refact
I added the
haskell layer plus
autocompletion which it seems to require. I also followed the documentation in configuring intero and hindent (though the style “johan-tibell” no longer seems required as hindent no longer supports multiple styles).
After adding a few other layers, my configuration layers in
~/.spacemacs looked like this:
I missed having a project sidebar (such as seems to be the default in editors like Atom). Eventually, I found that Spacemacs includes NeoTree, which makes a viable project sidebar. Toggle on/off with
SPC p t or
SPC f t for a file rather than project browser.
I also missed having a tab bar (for open files) such as that in Atom. There doesn’t seem to be anything built into Spacemacs for this. I tried the tabbar-layer, but it was pretty ugly.
After some searching, I figured I could rely on “helm-mini”. It lets you open search/select files from the open buffers with
SPC b b. Also searching/selecting for files in the same project is possible from projectile with
SPC p f.

I wanted my little indicator for the 80th column. Here, you need to tweak your
It was fun seeing the different themes available for Spacemacs. It’s best to install
themes-megapack layer (see my layers configuration above). I don’t mind the default
spacemacs-dark theme but here are some of my other favourites:

I finally settled on
