This package contains the Zephyr RTOS meta tool, 'west'.

DO NOT INSTALL WITH "python3 setup.py install".

Please use pip to install in development mode as documented below.

West is distributed in two pieces:

1. A bootstrap/wrapper script, which is distributed via PyPI.
2. The "main" west package and entry points, which are fetched by the bootstrap script.

This somewhat unusual arrangement is because:

• One of West's jobs is to manage interaction with Zephyr's multiple Git repositories, including its own.
• West is in its experimental stages and is moving quickly, meaning users need to stay on HEAD.

The default setup.py installs the wrapper script only.

To install the West bootstrapping/wrapper script from this package in development mode, clone this repository and run this from the top level directory:

$ pip3 install -e .

Then use the wrapper script to initialize a Zephyr installation with:

$ west init your/zephyr/install-dir
$ cd your/zephyr/install-dir
$ west <command>

The west init call will:

• create your/zephyr/install-dir
• clone the Zephyr manifest repository (whose URL can be overridden with the -u option, and branch with --mr / --manifest-rev)
• clone the latest West repository (the URL override is -w, and revision/branch override is --wr / --west-rev)

Running west <command> from :file:`your/zephyr/install-dir` or underneath it will invoke west in "wrapper" mode: any commands other than init will be delegated to the West tree pulled by west init.

This arrangement may seem familiar to Android (platform, not app) developers. The source management features of West were indeed inspired by the Android Repo tool's features, but West makes significant departures from Repo's behavior.

If you don't want to change your system outside of cloning this repository, you can also clone West's Git repository and run the package as a module:

$ python3 -m west

Only do this if you know what you're doing (and make sure to install the requirements as specified by the install_requires line in setup.py).
