New :rename command

[nik-rev]

You can use :move command to move the current buffer, but this is relative to Helix's current working directory.

Say your current working directory is ~/site/src/, and you are editing the ~/site/src/lib/command.ts file.

You want to rename it to typed.ts, you can do it with :move lib/typed.ts.

But it would be nice if we didn't need to specify the current file's directory.

When #11164 is merged, you'll be able to use mv %{d}/typed.ts but it would still be nice to have a :rename command., with a :rn alias.

I don't see us adding another command only to have such a small difference in behavior. Like you mentioned you should be able to use a variable in the future. Currently you can use <C-r>% to paste the current path and then <C-w> to remove the last segment, and then change the name.

This seems like a good use case for flags: :move --rename

Would be nice to be able to move based on a relative path to rename files.

e.g. for renaming foo.ts -> bar.ts
:move ./bar.ts

or for moving to a new folder (e.g. foo.ts -> bar/foo.ts)
:move ./bar/foo.ts
