One day, I noticed that there was no easy way to generate coverage badges for my Golang projects. So I made one (see above)!
To install the executeable (ensure your $PATH contains $GOPATH/bin):
go get github.com/jpoles1/gopherbadger
This program can be run in any Go project that is compatible with the built-in go cover tool, which will extract a coverage percentage based upon files from all of your Go code (even that in sub-packages). Just run gopherbadger in your project root directory.
To prevent saving of a .png badge:
gopherbadger -png=false
To update a .md file badge (note: comma-separated):
gopherbadger -md="README.md,coverage.md"
Manually set the coverage value (note: do not include %):
gopherbadger -md="README.md,coverage.md" -manualcov=95
Try running:
gopherbadger -h
