maximize.el

Maximize your emacs frames vertically or horizontally.

How to install:

Clone file into your emacs directory

cd ~/.emacs.d
git clone git@github.com:izawa/maximize.git

Add load path subdirectory recursively

(let ((default-directory "~/.emacs.d/"))
  (normal-top-level-add-subdirs-to-load-path))

Add require into your .emacs.

(require 'maximize)

Additional setting

If you want to bind Hot-keys, add setting lines like below.

(global-set-key [f9] 'maximize-toggle-frame-vmax)
(global-set-key [f11] 'maximize-toggle-frame-hmax)

y-pixel-ratio (default 0.9) controls the requested vertical text height as a fraction of the display height. When monitor geometry is available, the height is capped to the monitor work area minus the title bar, tool bar, and borders, and rounded down to whole lines. This prevents the frame from extending below the usable screen area on Emacs 31.1 / macOS 26.

Tests

emacs -Q --batch -L . -l test/maximize-test.el -f ert-run-tests-batch-and-exit
