[PATCH] stg delete --empty

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


`stg delete --empty` deletes all empty patches in series. Command
does nothing and exits with zero code if all patches are not empty.

--empty option can be useful in this workflow:

* you work on the patches
* you send patches to upstream (using stg export or stg mail)
* patches are committed to upstream after a while
* you do `git fetch && stg rebase origin`
* `stg rebase origin` makes applied to upstrem local patches empty
* now you can use stg delete --empty to cleanup
