Legend replacements. A config file containing legend replacements can be provided to change the legends to your liking. It should have a section named 'legends' and e.g. look like:

[legends]
KC_BLSLS=\
KC_QUOT='

It can then be provided on the commandline like:

$ keymapviz qmk_firmware/keyboards/lets_split/keymaps/default/keymap.c -c /path/to/config.properties

An example file is provided in the root of this project, named config.properties.

Output json file. This json file can be used in http://www.keyboard-layout-editor.com/.

$ keymapviz qmk_firmware/keyboards/lets_split/keymaps/default/keymap.c -t json -o 'lets_split{}.json'
$ ls lets_split*.json
lets_split0.json  lets_split1.json  lets_split2.json  lets_split3.json  lets_split4.json  lets_split5.json

Output fancy ascii art. Uses unicode symbols for drawing the box outlines.

$ keymapviz  -t fancy ~/qmk_firmware/keyboards/kbdclack/kaishi65/keymaps/default/keymap.c
