GitCoAuth is a simple .NET Core Global Tool that will help you generate co-authorship commit lines, as you should.
After installing, run it passing your co-author's GitHub username as a parameter. For instance:
gitcoauth lorenzck
will output the following line (and it will also automatically try to copy it to your clipboard):
Co-authored-by: Lorenz Cuno Klopfenstein <lorenzck@users.noreply.github.com>
Append the line to your commit message following this GitHub guide (that is leaving at least one empty line between the commit message and the co-authorship trailer). Once committed and pushed to GitHub, you and your co-authors will all have ownership of the commit. ✌
Run the following command from shell:
dotnet tool install -g dotnet-gitcoauth
To uninstall the tool again:
dotnet tool uninstall -g dotnet-gitcoauth
