Run it with no arguments to format all core code that has been changed. Default checks `origin/master` with `git diff`, branch can be changed using `-b <branch_name>`
Run it with `-a` to format all core code, or pass filenames on the command line to run it on specific files.
**Usage for specified files**:
```
qmk cformat [file1] [file2] [...] [fileN]
```
**Usage for all core files**:
```
qmk cformat -a
```
**Usage for only changed files against origin/master**:
```
qmk cformat
```
**Usage for only changed files against branch_name**:
```
qmk cformat -b branch_name
```
## `qmk compile`
This command allows you to compile firmware from any directory. You can compile JSON exports from <https://config.qmk.fm>, compile keymaps in the repo, or compile the keyboard in the current working directory.
**Usage for Configurator Exports**:
```
qmk compile <configuratorExport.json>
```
**Usage for Keymaps**:
```
qmk compile -kb <keyboard_name> -km <keymap_name>
```
**Usage in Keyboard Directory**:
Must be in keyboard directory with a default keymap, or in keymap directory for keyboard, or supply one with `--keymap <keymap_name>`
Ψ Compiling keymap with make clueboard/66/rev4:66_iso
...
```
or in keymap directory
```
$ cd ~/qmk_firmware/keyboards/gh60/satan/keymaps/colemak
$ qmk compile
Ψ Compiling keymap with make make gh60/satan:colemak
...
```
**Usage in Layout Directory**:
Must be under `qmk_firmware/layouts/`, and in a keymap folder.
```
qmk compile -kb <keyboard_name>
```
**Example**:
```
$ cd ~/qmk_firmware/layouts/community/60_ansi/mechmerlin-ansi
$ qmk compile -kb dz60
Ψ Compiling keymap with make dz60:mechmerlin-ansi
...
```
## `qmk flash`
This command is similar to `qmk compile`, but can also target a bootloader. The bootloader is optional, and is set to `:flash` by default.
To specify a different bootloader, use `-bl <bootloader>`. Visit the [Flashing Firmware](flashing.md) guide for more details of the available bootloaders.
This command allows you to convert from raw KLE data to QMK Configurator JSON. It accepts either an absolute file path, or a file name in the current directory. By default it will not overwrite `info.json` if it is already present. Use the `-f` or `--force` flag to overwrite.
**Usage**:
```
qmk kle2json [-f] <filename>
```
**Examples**:
```
$ qmk kle2json kle.txt
☒ File info.json already exists, use -f or --force to overwrite.
```
```
$ qmk kle2json -f kle.txt -f
Ψ Wrote out to info.json
```
## `qmk list-keyboards`
This command lists all the keyboards currently defined in `qmk_firmware`
**Usage**:
```
qmk list-keyboards
```
## `qmk list-keymaps`
This command lists all the keymaps for a specified keyboard (and revision).
**Usage**:
```
qmk list-keymaps -kb planck/ez
```
## `qmk new-keymap`
This command creates a new keymap based on a keyboard's existing default keymap.
