This is a simple demo of a maze generator using the Prim-Jarník algorithm. Outside of just generating mazes, you can also preset weights for some edges with a simple editor.

This program is lacking in a few (read a lot) departments, but fixing the jank has been left as an exercise for the reader.

• generate a maze: maze_generator
• generate a maze from a prelude file: maze_generator <prelude-file>
• edit/create a prelude file: maze_generator edit <prelude-file>

• left-mouse: apply weight to an edge
• right-mouse: remove weight from an edge
• scroll-wheel: change selected weight
• S-key: save the prelude (also saved on file exit)
• ESC-key or Q-key: exit
