Description

This layer provides basic Purescript editing support for spacemacs thanks to the following packages:

• purescript-mode
• psci
• psc-ide-emacs

Install

To use this configuration layer, add it to your ~/.spacemacs. You will need to add purescript to the existing dotspacemacs-configuration-layers list in this file.
