packageurl-go

Go implementation of the package url spec.

Install

go get -u github.com/package-url/packageurl-go

Versioning

The versions will follow the spec. So if the spec is released at 1.0. Then all versions in the 1.x.y will follow the 1.x spec.

Usage

Create from parts

package main

import (
	"fmt"

	"github.com/package-url/packageurl-go"
)

func main() {
	instance := packageurl.NewPackageURL("test", "ok", "name", "version", nil, "")
	fmt.Printf("%s", instance.ToString())
}

Parse from string

package main

import (
	"fmt"

	"github.com/package-url/packageurl-go"
)

func main() {
	instance, err := packageurl.FromString("test:ok/name@version")
	if err != nil {
		panic(err)
	}
	fmt.Printf("%#v", instance)
}

Test

Testing using the normal go test command. Using make test will pull the test fixtures shared between all package-url projects and then execute the tests.

$ make test
curl -L https://raw.githubusercontent.com/package-url/purl-test-suite/master/test-suite-data.json -o testdata/test-suite-data.json
