How to do `git mv` for renaming?

[Boscop]

About a year ago, Diesel changed the name format of the migrations that it generates.
I still have many migrations in the old format and want to use rnr to rename them into the new format.
But how can I do the renaming with git mv so that git properly recognizes that the folders were renamed?
If I just do rnr -f -D '(\d{4})(\d{2})(\d{2})(\d{6})' '$1-$2-$3-$4' ./*, git shows the files as being removed and new files added.
When I use git mv manually, it correctly shows them as renamed..

If you use rnr to rename files, git status will show you deleted/new files. Try to git add these changes to staged. git will detect that you renamed those files after adding them.

Closing since it is a git issue. Feel free to comment here if you have something more to add to the discussion.

I feel like this isn't entirely a git issue, what the issue raiser wants (and I also) is to be able to change the command that is run when renaming. qmv kind of offers this but doesn't work well with git mv because mv is an argument to the call.

Would it be a silly request for a custom command (with arguments) to be called instead of mv (or direct syscall)?

main...russkel:rnr:main

It's not great code by any means, but it works:

↳ ~/work/rnr/target/debug/rnr regex --exec "/usr/bin/git mv" -D -f test moo ./*
./test3 -> ./moo3
./test2 -> ./moo2

I am still not sure if this feature is useful in rnr and do not impact anything else. I will reopen the issue to have a deeper look.

Great. I haven't been able to find a tool that can do this, but your project was super easy to hack it into, so thanks for that.
