# recap

This library will map NAMED regex capture groups, to a tagged struct

```golang

package main

import "github.com/jeppech/recap"

type Person struct {

  Name string   `recap:"name"`

  Age int       `recap:"age"`

  Public bool   `recap:"public;default=false"`

  Fruits Fruits

}

type Fruits struct {

  Apple bool    `recap:"fruit;contains=apple"`

  Orange bool   `recap:"fruit;contains=orange"`

  Banana bool   `recap:"fruit;contains=banana"`

}

func main() {

  pers := Person{}

	rx := regexp.MustCompile(`(?P[A-Za-z]+) (?P\d+) (?:(?P(true|false)))?\W?\[(?P.*)\]`)

  err, match := recap.Parse(&pers, rx, "Jeppe 31 [orange banana]")

	if err != nil {

		log.Fatal(err)

	}

	if (match) {

		fmt.Printf("%+v\n", pers)

	} else {

		// did not match

	}

}

// {Name:Jeppe Age:31 Public:false Fruits:{Apple:false Orange:true Banana:true}}

```
