# QMK CLI

This page describes how to setup and use the QMK CLI.

# Overview

The QMK CLI makes building and working with QMK keyboards easier. We have provided a number of commands to simplify and streamline tasks such as obtaining and compiling the QMK firmware, creating keymaps, and more.

* [Global CLI](#global-cli)
* [Local CLI](#local-cli)
* [CLI Commands](#cli-commands)

# Requirements

The CLI requires Python 3.5 or greater. We try to keep the number of requirements small but you will also need to install the packages listed in [`requirements.txt`](https://github.com/qmk/qmk_firmware/blob/master/requirements.txt).

# Global CLI

QMK provides an installable CLI that can be used to setup your QMK build environment, work with QMK, and which makes working with multiple copies of `qmk_firmware` easier. We recommend installing and updating this periodically.

## Install Using Homebrew (macOS, some Linux)

If you have installed [Homebrew](https://brew.sh) you can tap and install QMK:

```
brew tap qmk/qmk
brew install qmk
export QMK_HOME='~/qmk_firmware' # Optional, set the location for `qmk_firmware`
qmk setup  # This will clone `qmk/qmk_firmware` and optionally set up your build environment
```

## Install Using easy_install or pip

If your system is not listed above you can install QMK manually. First ensure that you have python 3.5 (or later) installed and have installed pip. Then install QMK with this command:

```
pip3 install qmk
export QMK_HOME='~/qmk_firmware' # Optional, set the location for `qmk_firmware`
qmk setup  # This will clone `qmk/qmk_firmware` and optionally set up your build environment
```

## Packaging For Other Operating Systems

We are looking for people to create and maintain a `qmk` package for more operating systems. If you would like to create a package for your OS please follow these guidelines:

* Follow best practices for your OS when they conflict with these guidelines
    * Document why in a comment when you do deviate
* Install using a virtualenv
* Instruct the user to set the environment variable `QMK_HOME` to have the firmware source checked out somewhere other than `~/qmk_firmware`.

# Local CLI

If you do not want to use the global CLI there is a local CLI bundled with `qmk_firmware`. You can find it in `qmk_firmware/bin/qmk`. You can run the `qmk` command from any directory and it will always operate on that copy of `qmk_firmware`.

**Example**:

```
$ ~/qmk_firmware/bin/qmk hello
Ψ Hello, World!
```

## Local CLI Limitations

There are some limitations to the local CLI compared to the global CLI:

* The local CLI does not support `qmk setup` or `qmk clone`
* The local CLI always operates on the same `qmk_firmware` tree, even if you have multiple repositories cloned.
* The local CLI does not run in a virtualenv, so it's possible that dependencies will conflict

# CLI Commands

## `qmk cformat`

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 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 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.

**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
```

**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.

**Usage for Configurator Exports**:

```
qmk flash <configuratorExport.json> -bl <bootloader>
```

**Usage for Keymaps**:

```
qmk flash -kb <keyboard_name> -km <keymap_name> -bl <bootloader>
```

**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 docs`

This command starts a local HTTP server which you can use for browsing or improving the docs. Default port is 8936.

**Usage**:

```
qmk docs [-p PORT]
```

## `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 json-keymap`

Creates a keymap.c from a QMK Configurator export.

**Usage**:

```
qmk json-keymap [-o OUTPUT] filename
```

## `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] <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 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).

**Usage**:

```
qmk list-keymaps -kb planck/ez
```

## `qmk new-keymap`

This command creates a new keymap based on a keyboard's existing default keymap.

**Usage**:

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

## `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.

**Usage**:

```
qmk pytest
```
