This is the Zephyr RTOS meta tool, ``west``.
|
|
|
|
https://docs.zephyrproject.org/latest/guides/west/index.html
|
|
|
|
Installation
|
|
------------
|
|
|
|
Using pip::
|
|
|
|
pip3 install west
|
|
|
|
(Use ``pip3 uninstall west`` to uninstall it.)
|
|
|
|
Basic Usage
|
|
-----------
|
|
|
|
West lets you manage multiple Git repositories under a single directory using a
|
|
single file, called the *west manifest file*, or *manifest* for short.
|
|
By default the manifest file is named ``west.yml``.
|
|
You use ``west init`` to set up this directory, then ``west update`` to fetch
|
|
and/or update the repositories named in the manifest.
|
|
|
|
By default, west uses `upstream Zephyr's manifest file
|
|
<https://github.com/zephyrproject-rtos/zephyr/blob/main/west.yml>`_, but west
|
|
doesn't care if the manifest repository is a Zephyr tree or not.
|
|
|
|
For more details, see `Multiple Repository Management
|
|
<https://docs.zephyrproject.org/latest/guides/west/repo-tool.html>`_ in the
|
|
west documentation.
|
|
|
|
Example usage using the upstream manifest file::
|
|
|
|
mkdir zephyrproject && cd zephyrproject
|
|
west init
|
|
west update
|
|
|
|
What just happened:
|
|
|
|
- ``west init`` clones the upstream *west manifest* repository, which in this
|
|
case is the zephyr repository. The manifest repository contains ``west.yml``,
|
|
a YAML description of the Zephyr installation, including Git repositories and
|
|
other metadata.
|
|
|
|
- ``west update`` clones the other repositories named in the manifest file,
|
|
creating working trees in the installation directory ``zephyrproject``.
|
|
|
|
Use ``west init -m`` to specify another manifest repository. Use ``--mr`` to
|
|
use a revision to inialize from; if not given, the remote's default branch is used.
|
|
Use ``--mf`` to use a manifest file other than ``west.yml``.
|
|
|
|
Additional Commands
|
|
-------------------
|
|
|
|
West has multiple sub-commands. After running ``west init``, you can
|
|
run them from anywhere under ``zephyrproject``.
|
|
|
|
For a list of available commands, run ``west -h``. Get help on a
|
|
command with ``west <command> -h``.
|
|
|
|
West is extensible: you can add new commands to west without modifying its
|
|
source code. See `Extensions
|
|
<https://docs.zephyrproject.org/latest/guides/west/extensions.html>`_ in the
|
|
documentation for details.
|
|
|
|
Running the Tests
|
|
-----------------
|
|
|
|
First, install tox::
|
|
|
|
# macOS, Windows
|
|
pip3 install tox
|
|
|
|
# Linux
|
|
pip3 install --user tox
|
|
|
|
Then, run the test suite locally from the top level directory::
|
|
|
|
tox
|
|
|
|
See the tox configuration file, tox.ini, for more details.
|
|
|
|
Hacking on West
|
|
---------------
|
|
|
|
Installing from Source
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The `wheel`_ package is required to install west from source. See "Installing
|
|
Wheel" below if you don't have ``wheel`` installed.
|
|
|
|
To build the west wheel file::
|
|
|
|
# macOS, Linux
|
|
python3 setup.py bdist_wheel
|
|
|
|
# Windows
|
|
py -3 setup.py bdist_wheel
|
|
|
|
This will create a file named ``dist/west-x.y.z-py3-none-any.whl``,
|
|
where ``x.y.z`` is the current version in setup.py.
|
|
|
|
To install the wheel::
|
|
|
|
pip3 install -U dist/west-x.y.z-py3-none-any.whl
|
|
|
|
You can ``pip3 uninstall west`` to remove this wheel before re-installing the
|
|
version from PyPI, etc.
|
|
|
|
Editable Install
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
To run west "live" from the current source code tree, run this command from the
|
|
top level directory in the west repository::
|
|
|
|
pip3 install -e .
|
|
|
|
This is useful if you are actively working on west and don't want to re-package
|
|
and install a wheel each time you run it.
|
|
|
|
Installing Wheel
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
On macOS and Windows, you can install wheel with::
|
|
|
|
pip3 install wheel
|
|
|
|
That also works on Linux, but you may want to install wheel from your
|
|
system package manager instead -- e.g. if you installed pip from your
|
|
system package manager. The wheel package is likely named something
|
|
like ``python3-wheel`` in that case.
