Git Integration

yoyo is git-aware. It shows your current branch and provides commands for common git operations.

Branch display

When you're in a git repository, the REPL prompt shows the current branch:

main > _
feature/new-parser > _

On startup, the branch is also shown in the status information:

  git:   main

Show a summary of uncommitted changes (equivalent to git diff --stat):

/diff

Output:

 src/main.rs | 15 +++++++++------
 README.md   |  3 +++
 2 files changed, 12 insertions(+), 6 deletions(-)

If there are no uncommitted changes:

  (no uncommitted changes)

Show the actual diff content (line-by-line changes), not just a summary:

/git diff

Shows unstaged changes. To see staged changes instead:

/git diff --cached

List all branches, with the current branch highlighted in green:

/git branch

Create and switch to a new branch:

/git branch feature/my-new-feature

Show who last modified each line of a file, with colorized output:

/blame src/main.rs

Limit to a specific line range:

/blame src/main.rs:10-20

Output is colorized: commit hashes (dim), author names (cyan), dates (dim), line numbers (yellow).

Revert all uncommitted changes. This is equivalent to git checkout -- .:

/undo

Before reverting, /undo shows you what will be undone:

 src/main.rs | 15 +++++++++------
 1 file changed, 9 insertions(+), 6 deletions(-)
  ✓ reverted all uncommitted changes

If there's nothing to undo:

  (nothing to undo — no uncommitted changes)

yoyo's bash tool can run any git command. You can ask the agent directly:

> commit these changes with message "fix: handle empty input"
> show me the last 5 commits
> create a new branch called feature/parser

The agent has full access to git through its shell tool.
