This package allows use of repeated CLI flags defining HTTP headers, like:

## CLI usage

```bash

# Long format

mycommand --header "Accept: text/plain" --header "Authorization: bearer sometoken"

# Short format

mycommand -H "Accept: text/plain" -H "Authorization: bearer sometoken"

# Repeated headers are supported and combined

mycommand -H "X-Array-Header: value1" -H "X-Array-Header: value2"

# Will return a slice value with value1 and value2 for key  X-Array-Header

# Headers are canonicalized

mycommand -H "content-type: application/json"

# Will have key Content-Type

```

## Code usage

### Simple

```go

package main

import (

	"fmt"

	"github.com/spf13/pflag"

	"github.com/fgm/pflagheaders"

)

func main() {

	// HeaderFlag provides a preconfigured default flag

	h := pflagheaders.HeaderFlag()

	pflag.Parse()

	fmt.Printf("Headers:\n%s\n", h)

	// The resulting http.Header is available after Parse:

	fmt.Printf("Inner header:\n%#v\n", h.Header)

}

```

### In projects using spf13/cobra

```go

// In cmd/root.go

package cmd

import (

	pfh "github.com/fgm/pflagheaders"

	"github.com/spf13/cobra" // and others

)

var header = &pfh.Header{}

var rootCmd = &cobra.Command{

	/* generated by Cobra */

	Run: func(_ *cobra.Command, _ []string) { fmt.Println(header) }

}

func init() {

	cobra.OnInitialize(initConfig) // Generated by Cobra

	// ...other lines generated by Cobra

	// You can use the provided constants, or use other values.

	rootCmd.Flags().VarP(header, pfh.NameLong, pfh.NameShort, pfh.Help)

}

```
