git-hunk（吉特大块头）

/git-hunk - split changes into focused commits

Requires: uv tool install git-hunk (or pip install git-hunk)

Workflow

1. git-hunk list — see all hunks (file, id, +/- stats). No diffs.
2. git-hunk show [<id>...] when headers aren't clear enough (no args shows all).
3. Plan commits before staging. For each planned commit, list the hunk IDs (and -l line ranges for partial hunks). A single hunk may need to be split across commits. Ask the user if grouping is ambiguous.
4. Stage and commit each group: git-hunk stage <id1> <id2>... git commit -m "<type>: <description>"
5. git-hunk list again to check nothing got left behind.

Partial hunks

Line selection (-l) works with stage, unstage, and discard (requires single id):

• Include lines: git-hunk stage <id> -l 3,5-7
• Exclude lines: git-hunk stage <id> -l ^3,^5-7

Fixing mistakes

• git-hunk unstage <id1> <id2>... — move staged hunks back to working tree.
• git-hunk unstage <id> -l 3,5-7 — partially unstage specific lines.
• git-hunk discard <id1> <id2>... — permanently discard unstaged hunks (restore from HEAD).
• git-hunk discard <id> -l 3,5-7 — partially discard specific lines.

Notes

• IDs are content-based hashes, stable across partial staging, and support prefix matching
• git-hunk list [<file>...] — filter hunks by file path
• --staged / --unstaged to filter list and show (both search staged+unstaged by default)
• --json exists but plain output is usually enough
• One logical change per commit, conventional commit messages
