Re: Introducing west, Zephyr's meta-tool

Hi Carles,

How about pull request, how does west deals with them? Or it doesn't
and which case we have to deal with individual git repositories and
issue git push ourselves? This looks like repo which I never liked.

Hi all,

For a few months now we have been working on a meta-tool named west, designed to act both as a command-line tool to build, flash an debug Zephyr-based applications and also to manage the additional Git repositories that Zephyr will require in order to build in the near future.

West is written in Python 3, lives in its own repository [1] and its bootstrapper is available on PyPi [2].
As soon as we merge the topic-west [3] branch into master (which should happen in the next few days) you will need to install west in order to flash and debug, since those commands will rely on havig west present as part of your Zephyr workflow.

The updated west documentation will be online in the Zephyr documentation website [4] as soon as the topic-west branch is merged into master. In the meantime you can also look at the unrendered documentation sources in the topic-west branch [5] and the existing GitHub issues [6][7].

In order to install the west boostrapper (which you can do today) run:

# On Linux
pip3 install --user west

# On macOS and Windows
pip3 install west

Once the west bootstrapper is installed and the topic-west branch is merged into master, you will have 2 choices to get a west main installation.

1. Clone a new copy of the zephyr repository using west:

west init zephyrproject
cd zephyrproject
west update

2. Install west around an existing local zephyr clone:

Move the cloned zephyr/ repository to an empty enclosing folder (for example zephyrproject/zephyr/), and from this enclosing folder zephyrproject/ run:

west init -l zephyr/
west update
The -l <path to zephyr> parameter instructs west to use an existing local copy instead of cloning a remote repository.

Feedback and patches are welcome, but note that the feature will likely be merged as-is since we consider we have left ample time to raise any major issues regarding the workflow and decisions taken during the development of west. This is however only the beginning of west's (hopefully) long existence as the Zephyr command-line meta-tool, and it will certainly evolve and change considerably in the future with the help of the community.

Please submit feedback in the form of GitHub issues on the west repository itself [1] unless it affects features or functionality in the zephyr repository directly.

I will reply to this email once the topic-west branch is merged into master.

Thank you to everybody who has contributed so far!
