Re: commit dates, fundamentally those always change when rebasing because you're rewriting the commit object, but we don't touch the author date unless you explicitly reset it with metaedit
This is something you have to generally handle manually since absorb won't squash hunks with ambiguous targets, but I typically stack these branches and accept the dependency. I have had instances where this has backfired a little bit re: ordering but thankfully with JJ and the very patient little man in my computer named Codex it's easy to reorder them and end up with the same diff
Fwiw I generally solve this by using `jj commit` instead of `jj desc` unless I'm specifically targeting something that isn't my working copy. Technically it violates the "we want commands to be orthogonal" guideline we use to write Jujutsu (otherwise this would indeed be `jj desc; jj new`) but as a habit it's never let me down
Ah, thanks! That's a command I haven't learned yet, so I'll have to check it out. I learned jj from the tutorial that was posted and I don't think it covered `jj commit` at all.
I didn't cover it for various reasons, but I think it's good to teach now that I've had more time to consider this sort of thing, so the next iteration will likely start by beginning with jj commit.
In a pure `jj` model, commit might not even be necessary as it's own subcommand (since you could easily define an alias for `desc` followed by `new`). We're still living in a world where most people who would consider adopting `jj` are git users currently, so I wonder if starting with `commit` and then following it up with an explanation of "here's how you can change the commit message without needing to make a new commit" and "here's how you can make a new commit without changing the name of the current one" would end up fitting people's expectations better.
I tend to learn "bottom-up", so I like the new + describe as a way of learning, but people want to jump in and get going with tools, so commit fits that expectation better.
I'm the same way. I've learned over the years that this ends up being somewhat uncommon though, and one of the harder but more rewarding parts of helping people learn is figuring out where they're coming from and meeting them there. (I'm positive this is something you've been well aware of for a while though, probably longer than me!)
Indeed, though I don't think it can create fixup commits if that's what you're looking for. However, it might work great for that if you pair it with jj-spr: https://github.com/LucioFranco/jj-spr
