From 26b061007c1259ed4692554994961dd26874e63e Mon Sep 17 00:00:00 2001 From: Denton Liu Date: Tue, 29 Oct 2019 10:01:52 -0700 Subject: [PATCH] submodule: teach set-url subcommand Currently, in the event that a submodule's upstream URL changes, users have to manually alter the URL in the .gitmodules file then run `git submodule sync`. Let's make that process easier. Teach submodule the set-url subcommand which will automatically change the `submodule.$name.url` property in the .gitmodules file and then run `git submodule sync` to complete the process.
