git subtree

Manage project dependencies as subprojects. More information: https://manpages.debian.org/latest/git-man/git-subtree.1.html.

• Add a Git repository as a subtree:

git subtree add --prefix=path/to/directory/ --squash repository_url branch_name

• Update subtree repository to its latest commit:

git subtree pull --prefix=path/to/directory/ repository_url branch_name

• Merge recent changes up to the latest subtree commit into the subtree:

git subtree merge --prefix=path/to/directory/ --squash repository_url branch_name

• Push commits to a subtree repository:

git subtree push --prefix=path/to/directory/ repository_url branch_name

• Extract a new project history from the history of a subtree:

git subtree split --prefix=path/to/directory/ repository_url -b branch_name
