Emacs Variables Skill

Display Guidelines

E-ink Monitor Compatibility: User uses an e-ink monitor that only supports black, white, and grey.

• NEVER use colors (:foreground "red", :foreground "cyan", etc.)
• Use :weight bold, :weight light, :slant italic, :underline t for differentiation
• Standard Emacs faces (font-lock-*-face) are acceptable as they adapt to themes

Variable Basics

Define variable

(defvar my-var "default" "Documentation string.")
(defvar my-var nil)  ; define without overwriting
