Installation

Package

Cube is not available on any ELPA right now.

Quelpa

(quelpa '(cube :fetcher git
               :url "https://codeberg.org/akib/emacs-cube.git"))

Straight.el

(straight-use-package
 '(cube :type git :repo "https://codeberg.org/akib/emacs-cube.git"))

Manual

First, install Eagle as described in its README. Then put cube.el in your load-path.

Keybindings

To rotate any of the six faces clockwise, call one of the following commands:

Key	Command
f	cube-rotate-front
b	cube-rotate-back
l	cube-rotate-left
r	cube-rotate-right
u	cube-rotate-up
d	cube-rotate-down

If you want to rotate counter-clockwise, give single prefix argument (C-u) or negative argument (-) before the command. To rotate twice, either press the key twice or press give numeric argument 2 (2) and press the key once.

To shuffle the cube randomly, press S (cube-shuffle). You can use a custom seed yourself by calling it with prefix argument and entering the seed.

If you have scrambled the cube but can't solve, press R (cube-reset) to reset the cube.

To rotate the whole cube, you have the following commands and keybindings:

Key	Command
up	cube-camera-rotate-up
down	cube-camera-rotate-down
left	cube-camera-rotate-left
right	cube-camera-rotate-right
M-up	cube-camera-rotate-clockwise
M-down	cube-camera-rotate-counter-clockwise
C-p	cube-camera-rotate-up
C-n	cube-camera-rotate-down
C-b	cube-camera-rotate-left
C-f	cube-camera-rotate-right
M-p	cube-camera-rotate-counter-clockwise
M-n	cube-camera-rotate-clockwise
B	cube-camera-rotate-show-back
SPC	cube-camera-reset-rotation

If, for some reason, you want to render the cube again, press g (cube-render).

FAQ

The cube too big.

Increase camera distance by increasing the value of cube-camera-distance.

The cube is too slow.

Decrease resolution by setting cube-resolution. This will decrease the size of the cube, so you may want to increase the scale by increasing cube-scale.

The pixels are too big.

Increasing resolution by setting cube-resolution, or decrease scaling by setting cube-scale.

The animation is too long.

Decrease animation duration by setting cube-animation-duration. If this doesn't help then may be the number of animation step is too much to show in given time. In that case you need to decrease animation step by setting cube-animation-steps, or you may decrease resolution.
