gopkgs

gopkgs is a tool that provides list of available Go packages that can be imported.

This is an alternative to go list all, just faster.

Installation

$ go get -u github.com/uudashr/gopkgs/cmd/gopkgs

or, using Go 1.12+:

$ go install github.com/uudashr/gopkgs/v2/cmd/gopkgs@latest

Usage

Tool

$ gopkgs -help
Usage of gopkgs:
  -format string
    	custom output format (default "{{.ImportPath}}")
  -help
    	show this message
  -no-vendor
    	exclude vendor dependencies except under workDir (if specified)
  -workDir string
    	importable packages only for workDir


Use -format to custom the output using template syntax. The struct being passed to template is:
    type Pkg struct {
        Dir        string // directory containing package sources
        ImportPath string // import path of package in dir
        Name       string // package name
        Standard   bool   // is this package part of the standard Go library?
    }

Use -workDir={path} to speed up the package search. This will ignore any vendor package outside the package root.

Library

This project adheres to the Go modules release strategy by using the Major subdirectory approach.

Starting from version v2.0.3, you're able to use either github.com/uudashr/gopkgs or github.com/uudashr/gopkgs/v2 versions independently.

The tool cmd/gopkgs uses v2 package internally.

Example

Get package name along with the import path.

$ gopkgs -format "{{.Name}};{{.ImportPath}}"

Tips

Use -workDir={path} flag, it will speed up the package search by ignoring the external vendor.
