self keys

Key
	

Description

path
	

Optional. The path west init should clone the manifest repository into, relative to the west workspace topdir.

If not given, the basename of the path component in the manifest repository URL will be used by default. For example, if the URL is https://git.example.com/project-repo, the manifest repository would be cloned to the directory project-repo.

west-commands
	

Optional. This is analogous to the same key in a project sequence element.

import
	

Optional. This is also analogous to the projects key, but allows importing projects from other files in the manifest repository. See Manifest Imports.
