Emacs has built-in Scheme Mode. It provides basic features, such as syntax highlighting etc.
Guile is the GNU Ubiquitous Intelligent Language for Extensions, the official extension language for the GNU operating system.
Formerly known as PLT Scheme
Major Mode for editing Scheme
Geiser is a collection of Emacs major and minor mode, that can help Emacs to communicate to a foreign Scheme interpreter. It provides SLIME-like support for Racket and Guile.
Example config may look like this:
(defun turn-on-parenthesis-goodies () (rainbow-delimiters-mode 1) (paredit-mode 1)) (add-hook 'scheme-mode-hook 'turn-on-parenthesis-goodies) (load-file "C:/path-to-geiser/elisp/geiser.el") (setq geiser-active-implementations '(racket)) (setq geiser-racket-binary "C:/path-to-racket/racket.exe") (require 'quack)
Minor Mode for editing Scheme
- ParEdit is a mode for structured editing of S-expressions. Useful with any Lisp.
- RainbowDelimiters highlights parentheses, brackets, and braces according to their depth, each level in a different colour. Also available in ELPA.
