Open The Selected Lines In GitHub With Gbrowse

The vim-fugitive plugin comes with the :Gbrowse command.

Open the current file, blob, tree, commit, or tag in your browser at the upstream hosting provider. If a range is given, it is appropriately appended to the URL as an anchor.

I would try this from repositories hosted on GitHub and get an error. Reading a bit further into the :Gbrowse documentation I can see why.

Upstream providers can be added by installing an appropriate Vim plugin. For example, GitHub can be supported by installing rhubarb.vim, available at https://github.com/tpope/vim-rhubarb.

I was missing the vim-rhubarb plugin. After installing that, I can open the current file in GitHub by running :Gbrowse.

If I make a visual selection of any number of lines, then I can go into command mode again typing out Gbrowse with the automatically preceding visual selection tags. This will open the file on GitHub with those lines selected.
