West (Zephyr’s meta-tool)¶
The Zephyr project includes a swiss-army knife command line tool named
west. West is developed in its own repository. Like
docker, the top-level
west command takes some common
options, a sub-command to run, and then options and arguments for that
west [common-opts] <command> [opts] <args>
West’s built-in commands provide a multiple repository management system with features inspired by Google’s Repo tool and Git submodules. West simplifies configuration and is also pluggable: you can write your own west “extension commands” which add additional features to west. Zephyr uses this feature to provide conveniences for building applications, flashing and debugging them, and more.
It is possible not to use west for Zephyr development if you do not require these features, prefer to use your own tools, or want to eliminate the extra layer of indirection. However, this implies extra effort and expert knowledge.
You can run
west --help (or
west -h for short) to get top-level help
for available west commands, and
west <command> -h for detailed help on
The following pages document west’s
v0.6.x releases, and provide additional
context about the tool.
