Subtree (FREE)

• Used when there are nested repositories.
• Not recommended when the amount of dependencies is too large.
• For these cases we need a dependency control system.
• Command are painfully long so aliases are necessary.

Subtree Aliases

• Add: git subtree add --prefix <target-folder> <url> <branch> --squash
• Pull: git subtree pull --prefix <target-folder> <url> <branch> --squash
• Push: git subtree add --prefix <target-folder> <url> <branch>
• Ex: git config alias.sbp 'subtree pull --prefix st / git@gitlab.com:balameb/subtree-nested-example.git master --squash'

  # Add an alias
  # Add
  git config alias.sba 'subtree add --prefix st /
  git@gitlab.com:balameb/subtree-nested-example.git master --squash'
  # Pull
  git config alias.sbpl 'subtree pull --prefix st /
  git@gitlab.com:balameb/subtree-nested-example.git master --squash'
  # Push
  git config alias.sbph 'subtree push --prefix st /
  git@gitlab.com:balameb/subtree-nested-example.git master'

  # Adding this subtree adds a st dir with a readme
  git sba
  vi st/README.md
  # Edit file
  git status shows differences

  # Adding, or committing won't change the sub repo at remote
  # even if we push
  git add -A
  git commit -m "Adding to subtree readme"

  # Push to subtree repo
  git sbph
  # now we can check our remote sub repo
