Emacs Buffer 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

Buffer Basics

Get current buffer

(current-buffer)      ; returns buffer object
(buffer-name)         ; returns buffer name string
(buffer-file-name)    ; returns file path or nil
