Go SemVer Aliases

A simple Go package to create deduplicated version aliases based on valid SemVer release names.

The library takes care of optional prefixed releases (v) as well as all version names are deduplicated and sorted in lexicographic order.

For example this library can be used to create SemVer and custom aliases for tagging Docker images.

Usage

package main

import (
	"fmt"

	aliases "github.com/joseluisq/semver-aliases"
)

func main() {
	// 1. Create alias names based on a given release
	versionAliases := aliases.FromVersion("v1.0.0")
	fmt.Printf("%#v\n", versionAliases)
	//	[]string{"1", "1.0", "1.0.0"}

	extras := []string{"latest", "stable", "v1.0.0", "1.0"}
	composed := append(versionAliases, extras...)
	fmt.Printf("%#v\n", composed)
	//	[]string{"1", "1.0", "1.0.0", "latest", "stable", "v1.0.0", "1.0"}

	// 2. Or create alias names based on a list of names (deduplicated and sorted)
	tags := aliases.FromVersionNames(composed)
	fmt.Printf("%#v\n", tags)
	//	[]string{"1", "1.0", "1.0.0", "latest", "stable"}

	// 3. Or create version names with its items suffixed (sorted)
	suffixed := aliases.GetVersionNamesSuffixed(versionAliases, "linux-amd64")
	fmt.Printf("%#v\n", suffixed)
	//	[]string{"1-linux-amd64", "1.0-linux-amd64", "1.0.0-linux-amd64"}
}
