Wandering Around

Important

You realize that jj new can be used to safely browse the repository.

Running jj new X creates a new Change containing the exact same content as X. But it’s not X, it’s a separate jchange, so even if you edit files, you won’t modify X. So, it’s a safe sandbox to explore what’s inside X on your disk.

Interestingly, if you jump away with a second jj new and leave your Buffer Change empty, Jujutsu automatically abandons it.

This is a brilliant default! You can jump back and forth targeting different Changes using jj new:

• Without polluting your history with empty leftovers.
• Without risking unintentional modifications to historical commits.

In practice, this is a very cheap way to gain read-only access to your entire repository.

Conflict Resolution

Interestingly enough, the same mini-workflow:

jj new && (jj squash | jj revert)

is exceptionally handy for resolving conflicts. It’s time to tackle this topic!
