Jujutsu

Git-compatible VCS with a different data model — no staging area, changes are immediate. Every file is tracked in the working copy as "changes" (like commits without parents).

⚠️ Never use git for mutations in a jj repo — it corrupts history. Allowed: git log, git diff, git show, git blame, git grep.

Basic Workflow

Create a change, describe it, view history:

jj new                   # Start a new change (like working on a commit)
jj desc -m "feat: add login"  # Write the message
jj log                   # View history — this is your main view command
jj diff                  # See what changed in working copy
