jj new                   # Create new change
jj desc -m "feat: add feature"  # Set description
jj log                   # View history

Time Travel

jj next --edit           # Next child change
jj edit @-               # Parent change
jj new --before @ -m msg # Insert before current

Conflicts

bash

jj resolve              # Interactive conflict resolution
# Edit files, then continue

Templates & Revsets

bash

jj log -T 'commit_id ++ "\n" ++ description'

jj log -r 'remote_bookmarks()..'  # Not on remote
jj log -r 'author(name)'    # By author

Git Interop

jj bookmark track main@origin # Track remote

Advanced Commands

bash

jj bisect start         # Start bisection
jj bisect good          # Mark current as good
jj bisect bad           # Mark current as bad
jj fix                  # Run configured formatters on files
jj sign -r @            # Sign current revision
jj metaedit -r @ -m "new message"  # Edit metadata only

•Use conventional commits: type(scope): desc
•jj undo to revert operations
•jj op log to see operation history
•Bookmarks are like branches
•jj absorb is powerful for fixing up commits in a stack
