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 [-c] <configuratorExport.json>
Usage for Keymaps:
qmk compile [-c] [-e <var>=<value>] [-j <num_jobs>] -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
...
Parallel Compilation:
It is possible to speed up compilation by adding the -j/--parallel flag.
qmk compile -j <num_jobs> -kb <keyboard_name>
The num_jobs argument determines the maximum number of jobs that can be used. Setting it to zero will enable parallel compilation without limiting the maximum number of jobs.
qmk compile -j 0 -kb <keyboard_name>
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 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.
Usage for Configurator Exports:
qmk flash [-bl <bootloader>] [-c] [-e <var>=<value>] [-j <num_jobs>] <configuratorExport.json>
Usage for Keymaps:
qmk flash -kb <keyboard_name> -km <keymap_name> [-bl <bootloader>] [-c] [-e <var>=<value>] [-j <num_jobs>]
Listing the Bootloaders
qmk flash -b
This command lets you configure the behavior of QMK. For the full qmk config documentation see CLI Configuration.
Usage:
qmk config [-ro] [config_token1] [config_token2] [...] [config_tokenN]
This command opens a new shell in your qmk_firmware directory.
Note that if you are already somewhere within QMK_HOME (for example, the keyboards/ folder), nothing will happen.
To exit out into the parent shell, simply type exit.
Usage:
qmk cd
This command lets you connect to keyboard consoles to get debugging messages. It only works if your keyboard firmware has been compiled with CONSOLE_ENABLE=yes.
Usage:
qmk console [-d <pid>:<vid>[:<index>]] [-l] [-n] [-t] [-w <seconds>]
Examples:
Connect to all available keyboards and show their console messages:
qmk console
List all devices:
qmk console -l
Show only messages from clueboard/66/rev3 keyboards:
qmk console -d C1ED:2370
Show only messages from the second clueboard/66/rev3:
qmk console -d C1ED:2370:2
Show timestamps and VID:PID instead of names:
qmk console -n -t
Disable bootloader messages:
qmk console --no-bootloaders
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
Formats a JSON file in a (mostly) human-friendly way. Will usually correctly detect the format of the JSON (info.json or keymap.json) but you can override this with --format if neccesary.
Usage:
qmk format-json [-f FORMAT] <json_file>
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
Creates a keymap.c from a QMK Configurator export.
Usage:
qmk json2c [-o OUTPUT] filename
Creates a keymap.json from a keymap.c.
Note: Parsing C source files is not easy, therefore this subcommand may not work with your keymap. In some cases not using the C pre-processor helps.
Usage:
qmk c2json -km KEYMAP -kb KEYBOARD [-q] [--no-cpp] [-o OUTPUT] filename
Checks over a keyboard and/or keymap and highlights common errors, problems, and anti-patterns.
Usage:
qmk lint [-km KEYMAP] [-kb KEYBOARD] [--strict]
This command is directory aware. It will automatically fill in KEYBOARD and/or KEYMAP if you are in a keyboard or keymap directory.
Examples:
Do a basic lint check:
qmk lint -kb rominronin/katana60/rev2
This command lists all the keyboards currently defined in qmk_firmware
Usage:
qmk list-keyboards
This command lists all the keymaps for a specified keyboard (and revision).
This command is directory aware. It will automatically fill in KEYBOARD if you are in a keyboard directory.
Usage:
qmk list-keymaps -kb planck/ez
This command creates a new keyboard based on available templates.
Any arguments that are not provided will prompt for input. If -u is not passed and user.name is set in .gitconfig, it will be used as the default username in the prompt.
Usage:
qmk new-keyboard [-kb KEYBOARD] [-t {avr,ps2avrgb}] -u USERNAME
This command creates a new keymap based on a keyboard's existing default keymap.
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 cleans up the .build folder. If --all is passed, any .hex or .bin files present in the qmk_firmware directory will also be deleted.
Usage:
qmk clean [-a]
This command formats text files to have proper line endings.
Every text file in the repository needs to have Unix (LF) line ending. If you are working on Windows, you must ensure that line endings are corrected in order to get your PRs merged.
qmk format-text
This command formats C code using clang-format.
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 format-c [file1] [file2] [...] [fileN]
Usage for all core files:
qmk format-c -a
Usage for only changed files against origin/master:
qmk format-c
Usage for only changed files against branch_name:
qmk format-c -b branch_name
Usage:
qmk generate-compilation-database [-kb KEYBOARD] [-km KEYMAP]
Creates a compile_commands.json file.
Does your IDE/editor use a language server but doesn't quite find all the necessary include files? Do you hate red squigglies? Do you wish your editor could figure out #include QMK_KEYBOARD_H? You might need a compilation database! The qmk tool can build this for you.
This command needs to know which keyboard and keymap to build. It uses the same configuration options as the qmk compile command: arguments, current directory, and config files.
Example:
$ cd ~/qmk_firmware/keyboards/gh60/satan/keymaps/colemak
$ qmk generate-compilation-database
Ψ Making clean
Ψ Gathering build instructions from make -n gh60/satan:colemak
Ψ Found 50 compile commands
Ψ Writing build database to /Users/you/src/qmk_firmware/compile_commands.json
Now open your dev environment and live a squiggly-free life.
This command starts a local HTTP server which you can use for browsing or improving the docs. Default port is 8936.
Use the -b/--browser flag to automatically open the local webserver in your default browser.
This command runs docsify serve if docsify-cli is installed (which provides live reload), otherwise Python's builtin HTTP server module will be used.
Usage:
qmk docs [-b] [-p PORT]
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 can be used to browse the generated files.
Usage:
qmk generate-docs
This command generates a lookup table (LUT) header file for the RGB Lighting 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/rgblight/.
Usage:
qmk generate-rgb-breathe-table [-q] [-o OUTPUT] [-m MAX] [-c CENTER]
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
This command formats python code in qmk_firmware.
Usage:
