I repeat the steps I took here in a mini tutorial format.
Create a custom layer for Spacemacs
Start with creating the layer from within Spacemacs:
<SPC> : configuration-layer/create-layer <RET>
<RET> again to create the layer in the default directory
Choose a layer name, e.g.
Spacemacs then throws you into the packages.el for your new layer.
Now is a good time to study layers, but the gist is this:
- hook in the modes you’re layering in
(setq <your-layer>-packages ...)
- set the key combinations for your Evil Leader in the
(defun <your-layer>/init-<your-layer> () ...)form
- optionally define custom commands here and bind to them
PS The Evil Leader in Spacemacs is
SPC (YES! that’s where Spacemacs gets its name from).
Here’s what I came up with for Pixie. At the moment, it offers bindings to start the REPL, and eval s-expressions (and an option to jump to the REPL after evaluation).

It’s by no means complete, and I plan to implement basic functionality involving navigation, documentation, tests (Pixie test frameworks permitting), and evaluation of more forms.
