# Git Workflows

Advanced git operations for real-world development. Covers interactive rebase, bisect, worktree, reflog recovery, subtrees, submodules, sparse checkout, conflict resolution, and monorepo patterns.

## When to Use

- Cleaning up commit history before merging (interactive rebase)
- Finding which commit introduced a bug (bisect)
- Working on multiple branches simultaneously (worktree)
- Recovering lost commits or undoing mistakes (reflog)
- Managing shared code across repos (subtree/submodule)
- Resolving complex merge conflicts
- Cherry-picking commits across branches or forks
- Working with large monorepos (sparse checkout)

## Interactive Rebase

### Squash, reorder, edit commits

```bash
# Rebase last 5 commits interactively
git rebase -i HEAD~5

# Rebase onto main (all commits since diverging)
git rebase -i main
```

The editor opens with a pick list:

```
pick a1b2c3d Add user model
pick e4f5g6h Fix typo in user model
pick i7j8k9l Add user controller
pick m0n1o2p Add user routes
pick q3r4s5t Fix import in controller
```

Commands available:
```
pick   = use commit as-is
reword = use commit but edit the message
edit   = stop after this commit to amend it
squash = merge into previous commit (keep both messages)
fixup  = merge into previous commit (discard this message)
drop   = remove the commit entirely
```

### Common patterns

```bash
# Squash fix commits into their parent
# Change "pick" to "fixup" for the fix commits:
pick a1b2c3d Add user model
fixup e4f5g6h Fix typo in user model
pick i7j8k9l Add user controller
fixup q3r4s5t Fix import in controller
pick m0n1o2p Add user routes

# Reorder commits (just move lines)
pick i7j8k9l Add user controller
pick m0n1o2p Add user routes
pick a1b2c3d Add user model

# Split a commit into two
# Mark as "edit", then when it stops:
git reset HEAD~
git add src/model.ts
git commit -m "Add user model"
git add src/controller.ts
git commit -m "Add user controller"
git rebase --continue
```
