Jujutsu (jj) Version Control System

Overview

Jujutsu is a powerful Git-compatible version control system that combines ideas from Git, Mercurial, Darcs, and adds novel features. It uses Git repositories as a storage backend, making it fully interoperable with existing Git tooling.

Key differentiators from Git:

• Working copy is automatically committed (no staging area)
• Conflicts can be committed and resolved later
• Automatic rebasing of descendants when commits change
• Operation log enables easy undo of any operation
• Revsets provide powerful commit selection
• Change IDs stay stable across rewrites (unlike commit hashes)
