Racket layer
Description
Adds support for the Racket programming language.
Features:
- Syntax highlighting with
racket-mode - Test runner
- Interactive REPL
- Code navigation with
gtags - Structurally safe editing using optional evil-cleverparens
Install
To use this configuration layer, add it to your ~/.spacemacs. You will need to
add racket to the existing dotspacemacs-configuration-layers list in this
file. You will also need DrRacket installed. Alternatively, one can use the
"Minimal Racket" installation, and then run the following command.
raco pkg install drracketStructurally safe editing
This layer adds support for evil-cleverparens which allows to safely edit
lisp code by keeping the s-expressions balanced.
By default this mode is not activated. You can turn it on locally on the
active buffer with SPC m T s (s for safe).
To turn it on automatically for all racket buffers call the following
function in your dotspacemacs/user-config function:
(spacemacs/toggle-evil-safe-lisp-structural-editing-on-register-hook-racket-mode)or to enable it for all supported modes:
(spacemacs/toggle-evil-safe-lisp-structural-editing-on-register-hooks)
When enabled the symbol 🆂 should be displayed in the mode-line.
