# Subtree
|
||
|
|
|
||
|
|
- 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'`
|
||
|
|
|
||
|
|
```shell
|
||
|
|
# 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
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
```shell
|
||
|
|
# 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
|
||
|
|
```
