# pkgextract

A library for extracting a set of Go packages that depend on one another.

## Example

Extract the `cmd/go/internal/modload` package from [golang/go](https://github.com/golang/go), along with all the package it depends on, replacing `internal` with `_internal_` in import paths.

```go

package main

import (

	"log"

	"path/filepath"

	"strings"

	"github.com/hmarr/pkgextract"

)

func main() {

	extractor := pkgextract.NewPackageExtractor(pkgextract.PackageExtractorOptions{

		InitialPkg: "cmd/go/internal/modload",

		OutputRoot: "./out",

		ImportRewriter: func(importPath string) string {

			newPath := strings.Replace(importPath, "internal", "_internal_", -1)

			return filepath.Join("github.com/dependabot/gomodules-extracted", newPath)

		},

		Filter: func(importPath string) bool {

			return strings.Contains(importPath, "internal")

		},

	})

	if err := extractor.Run(); err != nil {

		log.Fatal(err)

	}

}

```
