# 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 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](flashing) 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 can also flash binary firmware files (hex or bin) such as the ones produced by [Configurator](https://config.qmk.fm).

**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>]
```

**Usage for pre-compiled firmwares**:

**Note**: The microcontroller needs to be specified (`-m` argument) for keyboards with the following bootloaders:
* HalfKay
* QMK HID
* USBaspLoader

ISP flashing is also supported with the following flashers and require the microcontroller to be specified:
* USBasp
* USBtinyISP

```
qmk flash [-m <microcontroller>] <compiledFirmware.[bin|hex]>
```

**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).

**Usage**:

```
qmk config [-ro] [config_token1] [config_token2] [...] [config_tokenN]
```

## `qmk cd`

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
```

## `qmk find`

This command allows for searching through keyboard/keymap targets, filtering by specific criteria. `info.json` and `rules.mk` files contribute to the search data, as well as keymap configurations, and the results can be filtered using "dotty" syntax matching the overall `info.json` file format.

For example, one could search for all keyboards powered by the STM32F411 microcontroller:

```
qmk find -f 'processor==STM32F411'
```

The list can be further constrained by passing additional filter expressions:

```
qmk find -f 'processor==STM32F411' -f 'features.rgb_matrix==true'
```

The following filter expressions are supported:

 - `key == value`: Match targets where `key` is equal to `value`. May include wildcards such as `*` and `?`.
 - `key != value`: Match targets where `key` is not `value`. May include wildcards such as `*` and `?`.
 - `key < value`: Match targets where `key` is a number less than `value`.
 - `key > value`: Match targets where `key` is a number greater than `value`.
 - `key <= value`: Match targets where `key` is a number less than or equal to `value`.
 - `key >= value`: Match targets where `key` is a number greater than or equal to `value`.
 - `exists(key)`: Match targets where `key` is present.
 - `absent(key)`: Match targets where `key` is not present.
 - `contains(key, value)`: Match targets where `key` contains `value`. Can be used for strings, arrays and object keys.
 - `length(key, value)`: Match targets where the length of `key` is `value`. Can be used for strings, arrays and objects.

You can also list arbitrary values for each matched target with `--print`:

```
qmk find -f 'processor==STM32F411' -p 'keyboard_name' -p 'features.rgb_matrix'
```

**Usage**:

```
qmk find [-h] [-km KEYMAP] [-p PRINT] [-f FILTER]

options:
  -km KEYMAP, --keymap KEYMAP
                        The keymap name to build. Default is 'default'.
  -p PRINT, --print PRINT
                        For each matched target, print the value of the supplied info.json key. May be passed multiple times.
  -f FILTER, --filter FILTER
                        Filter the list of keyboards based on their info.json data. Accepts the formats key=value, function(key), or function(key,value), eg. 'features.rgblight=true'. Valid functions are 'absent', 'contains', 'exists' and 'length'. May be passed multiple times; all filters need to match. Value may include wildcards such as '*' and '?'.
```

## `qmk console`

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
```

## `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 necessary.

**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`

**Usage**:

```
qmk json2c [-o OUTPUT] filename
```

## `qmk c2json`

**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
```

**Examples**:

```
qmk c2json -km default -kb handwired/dactyl_promicro
```

or with filename:

# 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](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.
