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.
This command is directory aware. It will automatically fill in KEYBOARD and/or KEYMAP if you are in a keyboard or keymap 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>`
```
qmk compile
```
**Usage for building all keyboards that support a specific keymap**:
```
qmk compile -kb all -km <keymap_name>
```
**Example**:
```
$ qmk config compile.keymap=default
$ cd ~/qmk_firmware/keyboards/planck/rev6
$ qmk compile
Ψ Compiling keymap with make planck/rev6:default
...
```
or with optional keymap argument
```
$ cd ~/qmk_firmware/keyboards/clueboard/66/rev4
$ qmk compile -km 66_iso
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 is directory aware. It will automatically fill in KEYBOARD and/or KEYMAP if you are in a keyboard or keymap directory.
This command examines your environment and alerts you to potential build or flash problems. It can fix many of them if you want it to.
**Usage**:
```
qmk doctor [-y] [-n]
```
**Examples**:
Check your environment for problems and prompt to fix them:
qmk doctor
Check your environment and automatically fix any problems found:
qmk doctor -y
Check your environment and report problems only:
qmk doctor -n
## `qmk info`
Displays information about keyboards and keymaps in QMK. You can use this to get information about a keyboard, show the layouts, display the underlying key matrix, or to pretty-print JSON keymaps.
**Usage**:
```
qmk info [-f FORMAT] [-m] [-l] [-km KEYMAP] [-kb KEYBOARD]
```
This command is directory aware. It will automatically fill in KEYBOARD and/or KEYMAP if you are in a keyboard or keymap directory.
**Examples**:
Show basic information for a keyboard:
qmk info -kb planck/rev5
Show the matrix for a keyboard:
qmk info -kb ergodox_ez -m
Show a JSON keymap for a keyboard:
qmk info -kb clueboard/california -km default
## `qmk json2c`
Creates a keymap.c from a QMK Configurator export.
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 docs`
This command starts a local HTTP server which you can use for browsing or improving the docs. Default port is 8936.
This command allows you to generate QMK documentation locally. It can be uses for general browsing or improving the docs. External tools such as [serve](https://www.npmjs.com/package/serve) can be used to browse the generated files.
**Usage**:
```
qmk generate-docs
```
## `qmk generate-rgb-breathe-table`
This command generates a lookup table (LUT) header file for the [RGB Lighting](feature_rgblight.md) feature's breathing animation. Place this file in your keyboard or keymap directory as `rgblight_breathe_table.h` to override the default LUT in `quantum/`.
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 pyformat`
This command formats python code in `qmk_firmware`.
**Usage**:
```
qmk pyformat
```
## `qmk pytest`
This command runs the python test suite. If you make changes to python code you should ensure this runs successfully.
