How to move around to changes and commits

[gltzch]

I made a jj commit with the new Justfile. git status showed it was on a detached head. I git switch main and now the Justfile is gone. When I run jj abandon the current change ID changes but still exists.

How to I make kyxtyxlx the current active thing I am working on?

My goal is to have the Justfile exist again, and have the contents before it disappeared.

$ jj log

    Initial commit

I believe git got in a detached HEAD state when I re-wrote the author on an immutable commit.

 jj desc --reset-author --no-edit  --ignore-immutable u

Thank you.

Use jj edit kyxtyxlx to edit a specific change.

git switch foo will always result in jj creating a new empty change on top of foo. There isn't a way to do the equivalent of jj edit using a git command.

By the way, git will almost always be in a detached HEAD state while using jj. This is normal and not a problem. jj will keep git's index and HEAD up to date as you create and edit revisions.

In jj, it's normal to be in a "detached head" state. I believe pretty much every jj command that changes the position of the working copy commit will put you in a "detached head" state on the git side (even something as simple as jj new or jj edit).
