The idiom here is use `edit` if you want to edit a commit, and use `new` if you want to make a new commit. This works identically whether you specify the commit via branch name or commit id. I'm not sure why people are saying not to use `edit` ever. It's basically just a shorthand for staging and amending changes in an existing commit, and there's still a use case for that; it's just not "I want to see the changes on this old branch".

You know, you guys have fun with that, I'll continue using git which (probably) has the same amount of warts, but I already know them. I'll continue to refer new VCS users to jj, seems a lot easier to learn, but really don't have the interest to re-learn a bunch of ever-changing idioms.

I disagree with the people saying "never use edit". There are plenty of people saying conflicting things about git too, and I'd argue that understanding edit versus new isn't anywhere close to the level of wart that having to get people to agree on merging versus rebasing. Like you said though, have fun with that!

jj has far fewer warts than git. You don’t have to learn every jj idiom, you just have to find a workflow you like, which you will, quickly, because it’s so easy to use. Personally I don’t know why anyone uses `edit` but if they like it then I’m happy for them.

No system is perfect, but there's nothing wrong with `jj edit` and `jj new`. Both commands are completely reasonable and do what you think they would do.

I think it's because it's easy to make annoying mistakes (still easy to fix with undo) with edit. And it gains relatively little over new+squash. Edit is a useful power-feature, but I think for a novice, "never use it, only use the more well understood workflow of new+squash" is a good heuristic.

"jj new" is like "I'm going to make some changes", then you do "jj squash" to say "OK these look good enough to commit".

If you work this way you're "always" in a WIP state. And if you switch to another spot you won't lose your work, cuz it's persisted.

The end result if you work like this is you don't need stashing, since you get "free" stashing in your commit tree, which is more likely what people want (and if it's not... rebasing is easy so just move the node/`jj duplicate` it!)

`jj edit` exists but I think it's just not what people want in the default case at all. In exchange: rebasing "just works", stashing is not a thing to think about, and you don't lose your work

`edit` is still useful; just, for ..editing (!) something, instead of viewing it.

If you have some unfinished changes at the tip and want to temporarily checkout something 2 weeks ago, you `jj new` to there (similar to `git stash; git switch whatever`), and then later `jj edit your-old-tip` to go back (equivalent to `git switch main; git stash pop`; I think `jj edit` being an extended replacement for stash-popping things is a reasonable way to think about it). (and if you don't have any uncommitted changes, you always `jj new`)

jj also has a concept of immutable commits (defaulting to include tagged commits, and trunk at origin, which it'll disallow editing as a layer of defense)

jj edit has good use cases, but it's not the default command you need. For instance, say you were working on some changes but had to change branches for a few minutes to do something. If you didn't manage to create a commit and want to go back to the previous staging area, you would use the jj edit command rather than jj new. It's very intuitive in my experience, something I can't say is true for managing git commits (unless you've spent years forcing it into muscle memory). I never need to run jj help. I run help commands with git all the time.
