git-browse

#!/usr/bin/env bash
#
# Open current repository page on default browser
#
# $1 - Optional remote name, defaults to origin
#
# Examples
#
#   git browse
#   git browse gitlab
#
#
# Caveats
#
# Since I work mainly on macOS, this will rely on the 'open' command to work. If `open` is not
# available, it will simple print the browser url to stdout (You can still use this in linux,
# something along the lines of `xdg-open` $(git browse))
#
# I'm not sure which is the most common open command on linux, so I chose to leave it out.
# Suggestions are welcome
