open_repo is a bash function opening the repo page of the current git project from the terminal.
In order to use the function in the terminal, the script needs to be sourced from .bashrc or any file loaded on shell startup. See following sample.
# .bashrc
# ...
source /path/to/openrepo.sh
After sourcing the script, it can be used from within a terminal by calling the repo function.
The browser will be opened at the remote git repository page.
$ repo
opening https://github.com/schilli91/open_repo
In case the function is not called inside a git project, an error message is displayed. Also, the browser will not be opened.
$ repo
ERROR: This isn't a git project.
