Props

Command line flags made simple

Installation

go get -u github.com/libgolang/props

Usage

import (
  "fmt"
  "github.com/libgolang/props"
)

func main() {
  if props.IsSet("name") {
    fmt.Printf("My Name is %s\n", props.GetProp("name"))
  } else {
    fmt.Printf("No name given\n")
  }
}

Why

Does not require pre-defining properties. It dynamically figures out properties based on os.Args
Does no require 3rd party libraries
Just three functions GetProp, IsSet and GetArgs

Features

Arguments with two dashes and an equal sign are interpreted as properties with a value. e.g.: --prop-name=value
Arguments with two dashes and NO equal sign will interpret the next argument as a value. If no argument is followed by the property, then it will have an empty value. e.g.: --prop-name value then GetProp("prop-name"): "value" and --prop-name --some-other-property then GetProp("prop-name"): ""
Arguments with one dash are interperted as Flags. If a value is passed to the flag it is igned and used as an argument in GetArgs(). e.g.: -p then IsSet("p") : true
Any argument not part of a flag or a property is added to the argument list and they can be retrived by calling GetArgs().
