Emacs: Proportional Font
variable-pitch-mode to toggle between fixed-width and variable-width font.
(monospace vs proportional)
The font change is for current file/buffer only.
Proportional font is useful for reading info doc, email, etc. Proportional font is easier to read, and shows 20 or more characters per line. It also works great for coding too (except Python). Try it. You may be surprised.
(Thanks to Oscar Carlsson for suggesting
Setup Proportional Font by Major Mode
Here's how to make some mode always use proportional font.
(progn ;; use variable-width font for some modes (defun xah-use-variable-width-font () "Set current buffer to use variable-width font." (variable-pitch-mode 1) ;; (text-scale-increase 1 ) ) (add-hook 'nxml-mode-hook 'xah-use-variable-width-font) (add-hook 'emacs-lisp-mode-hook 'xah-use-variable-width-font) (add-hook 'js-mode-hook 'xah-use-variable-width-font) (add-hook 'css-mode-hook 'xah-use-variable-width-font) (add-hook 'html-mode-hook 'xah-use-variable-width-font) )
Alternatively, you can use the following code:
(defun xah-set-font-to-monospace () "Change font in current window to a monospaced font." (interactive) (set-frame-font "DejaVu Sans Mono" t) ) (defun xah-set-font-to-variable-width () "Change font in current window to a variable-width font." (interactive) (set-frame-font "DejaVu Sans" t) )
