QMK CLI Commands

User Commands

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.

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>

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 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

qmk config

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]

qmk doctor

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 format-json

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>

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.

Usage:

qmk json2c [-o OUTPUT] filename

qmk c2json

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

qmk lint

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

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).

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

qmk new-keyboard

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

qmk new-keymap

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.

Usage:

qmk new-keymap [-kb KEYBOARD] [-km KEYMAP]

qmk clean

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]

Developer Commands

qmk format-text

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

qmk format-c

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

qmk generate-compilation-database

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.

qmk docs

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.
