Overview

Package kingpin provides command line interfaces like this:

$ chat
usage: chat [<flags>] <command> [<flags>] [<args> ...]

Flags:
  --debug              enable debug mode
  --help               Show help.
  --server=127.0.0.1   server address

Commands:
  help <command>
    Show help for a command.

  post [<flags>] <channel>
    Post a message to a channel.

  register <nick> <name>
    Register a new user.

$ chat help post
usage: chat [<flags>] post [<flags>] <channel> [<text>]

Post a message to a channel.

Flags:
  --image=IMAGE   image to post

Args:
  <channel>   channel to post to
  [<text>]    text to post
$ chat post --image=~/Downloads/owls.jpg pics

From code like this:

package main

import "gopkg.in/alecthomas/kingpin.v2"

var (
  debug    = kingpin.Flag("debug", "enable debug mode").Default("false").Bool()
  serverIP = kingpin.Flag("server", "server address").Default("127.0.0.1").IP()

  register     = kingpin.Command("register", "Register a new user.")
  registerNick = register.Arg("nick", "nickname for user").Required().String()
  registerName = register.Arg("name", "name of user").Required().String()

  post        = kingpin.Command("post", "Post a message to a channel.")
  postImage   = post.Flag("image", "image to post").ExistingFile()
  postChannel = post.Arg("channel", "channel to post to").Required().String()
  postText    = post.Arg("text", "text to post").String()
)

func main() {
  switch kingpin.Parse() {
  // Register user
  case "register":
    println(*registerNick)

  // Post message
  case "post":
    if *postImage != nil {
    }
    if *postText != "" {
    }

func (TokenType) String

func (t TokenType) String() string

type Value

type Value interface {
	String() string
	Set(string) error
}

Value is the interface to the dynamic value stored in a flag. (The default value is represented as a string.)

If a Value has an IsBoolFlag() bool method returning true, the command-line parser makes --name equivalent to -name=true rather than using the next command-line argument, and adds a --no-name counterpart for negating the flag.

Example

This example ilustrates how to define custom parsers. HTTPHeader cumulatively parses each encountered --header flag into a http.Header struct.

Code:

package kingpin

import (
	"fmt"
	"net/http"
	"strings"
)

type HTTPHeaderValue http.Header

func (h *HTTPHeaderValue) Set(value string) error {
	parts := strings.SplitN(value, ":", 2)
	if len(parts) != 2 {
		return fmt.Errorf("expected HEADER:VALUE got '%s'", value)
	}
	(*http.Header)(h).Add(parts[0], parts[1])
	return nil
}

func (h *HTTPHeaderValue) Get() interface{} {
	return (http.Header)(*h)
}

func (h *HTTPHeaderValue) String() string {
	return ""
}

func HTTPHeader(s Settings) (target *http.Header) {
	target = new(http.Header)
	s.SetValue((*HTTPHeaderValue)(target))
	return
}

// This example ilustrates how to define custom parsers. HTTPHeader
// cumulatively parses each encountered --header flag into a http.Header struct.
func ExampleValue() {
	var (
		curl    = New("curl", "transfer a URL")
		headers = HTTPHeader(curl.Flag("headers", "Add HTTP headers to the request.").Short('H').PlaceHolder("HEADER:VALUE"))
	)

	curl.Parse([]string{"-H Content-Type:application/octet-stream"})
	for key, value := range *headers {
		fmt.Printf("%s = %s\n", key, value)
	}
}
