jj absorb dry run

[ucirello]

Hi,

Is there a way to see what jj absorb will do before running it? I know I can use jj op show -p right after calling to see what it has done, but sometimes I would like to massage the code a bit further before summoning absorb.

Any ideas?

I believe there's currently no way to do that. You could do something like save the results of jj op show -p immediately afterwards, and then unconditionally run jj undo, in order to accomplish a kind of "preview"/"speculation" workflow.

[tangential] There's some related design discussion (albeit for jj fix instead of jj absorb) at #3805 (comment), where @ilyagr was suggesting creating child commits instead of modifying the commits directly.

Perhaps, it can be achieved with #2562.

It's also nice if we have jj absorb --interactive which will open TUI like the current builtin diff editor (but with annotation and selector of destination commits.)
