# QMK Format
`qmkfmt` is a tool to format the `keymaps` section of a `keymap.c` file in [qmk](https://qmk.fm/).
It formats each `LAYOUT` entry under `keymaps` into a grid with aligned columns.
If the `--split-spaces` argument is passed, it inserts the given nubmer of spaces in the center of each layout.
If a row has less than the maximum number of columns (e.g. a thumb cluster), it is centered.
If `clang-format` is available on `$PATH`, `qmkfmt` will invoke it to format the rest of the file.
`qmkfmt` infers the number of rows from the number of lines in each `LAYOUT`.
