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().
