What Is This

The langtools repo contains packages and tools that we at ActiveState have developed as part of the ActiveState Platform. The platform provides automated language builds, where you can pick a language core and a set of packages to be built on a variety of platforms. Since building the platform requires us to understand a number of language package ecosystems, we are building tools for working with these ecosystems.

Version Parsing

This repo contains a Go package for version parsing, github.com/ActiveState/langtools/pkg/version:

package main

import (
	"fmt"
	"log"

	"github.com/ActiveState/langtools/pkg/version"
)

func main() {
	v, err := version.ParseGeneric("1.2")
	if err != nil {
		log.Fatalf("Could not parse 1.2 as a generic version: %s", err)
	}
	fmt.Printf("Parsed as %v\n", v.Decimal)
	// Prints:
	// Parsed as [1 2 0]
}

Name Normalization

Some language ecosystems have a concept of name normalization for package names. This repo contains a Go package for name normalization, github.com/ActiveState/langtools/pkg/name:

package main

import (
	"fmt"

	"github.com/ActiveState/langtools/pkg/name"
)

func main() {
	norm := name.NormalizePython("backports.functools_lru_cache")
	fmt.Printf("Normalized as %s\n", norm)
	// Prints:
	// Normalized as backports-functools-lru-cache
}

parseversion Command Line Tool

This repository also contains the code for a parseversion CLI tool. You can install this by running go get github.com/ActiveState/langtools/cmd/parseversion. Run parseversion --help for details on this tool.
