weezard

Populates golang structs with questions on the command line. The library takes its metadata from struct field tags in the same way you would for json, etc.

Reference docs: http://godoc.org/github.com/aliafshar/weezard

An example will make it more clear, perhaps.

package weezard_test

import (
  "log"
  "github.com/aliafshar/weezard"
)

func Example() {
  type UserInfo struct {
    Name string `question:"default,What is your name?"`
    DateOfBirth string `question:",What is your date of birth?"`
  }

  u := &UserInfo{}
  err := weezard.Ask(u)
  if err != nil {
    log.Fatalln(err)
  }
  log.Printf("%#v", u)
}

This looks like:

What is your name? Name [default=]Ali
What is your date of birth? DateOfBirth [default=]1999-09-09
2014/11/09 17:32:47 &main.UserInfo{Name:"Ali", DateOfBirth:"1999-09-09"}

The tag format is:

question:"<default>,<question>"
