This is a visualizer for keymaps, similar to keymap which was used as a starting point. Requires python >= 3.8, pyyaml and pydantic packages (pip install --user pyyaml pydantic) for reading and validating input YAML configs.

• Supports non-split and custom-sized layouts
  • Arbitrary row/col sizes, number of thumb keys for splits
• Decouples data and drawing logic by reading physical layout and keymap definitions from YAML files
• Supports hold-tap keys
• Supports horizontal Nu keys for integer N > 1
  • Defined by consecutive identical non-null key definitions
• Supports combos
  • Only two neighboring positions (horizontal or vertical)
  • Uses ZMK-like position indices (starting from 0, going right then down)
• Layer labels
• Slightly different styling
