# QMK CLI Commands # User Commands ## `qmk compile` This command allows you to compile firmware from any directory. You can compile JSON exports from , 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] ``` **Usage for Keymaps**: ``` qmk compile [-c] [-e =] [-j ] -kb -km ``` **Usage in Keyboard Directory**: Must be in keyboard directory with a default keymap, or in keymap directory for keyboard, or supply one with `--keymap ` ``` qmk compile ``` **Usage for building all keyboards that support a specific keymap**: ``` qmk compile -kb all -km ``` **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 ``` **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 -kb ``` 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 ``` ## `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 `. 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. **Usage for Configurator Exports**: ``` qmk flash [-bl ] [-c] [-e =] [-j ] ``` **Usage for Keymaps**: ``` qmk flash -kb -km [-bl ] [-c] [-e =] [-j ] ``` **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](cli_configuration.md). **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] ``` ## `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 ` 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](https://clang.llvm.org/docs/JSONCompilationDatabase.html)! 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. **Usage**: ``` qmk docs [-b] [-p PORT] ``` ## `qmk generate-docs` 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/rgblight/`. **Usage**: ``` qmk generate-rgb-breathe-table [-q] [-o OUTPUT] [-m MAX] [-c CENTER] ``` ## `qmk kle2json` 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] ``` **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 format-python` This command formats python code in `qmk_firmware`. **Usage**: ``` qmk format-python ``` ## `qmk pytest` This command runs the python test suite. If you make changes to python code you should ensure this runs successfully. **Usage**: ``` qmk pytest ```
