Golang Licenses Examples

Example #1

File: camlegal_test.go Project: rfistman/camlistore

func TestLicenses(t *testing.T) {
	legal.RegisterLicense("dummy")
	licenses := legal.Licenses()
	if len(licenses) < 2 {
		t.Fatal("no second license text")
	}
	if licenses[1] != "dummy" {
		t.Error("license text mismatch")
	}
}

Example #2

File: cmdmain.go Project: rfistman/camlistore

// PrintLicenses prints all the licences registered by go4.org/legal for this program.
func PrintLicenses() {
	for _, text := range legal.Licenses() {
