flagmap

Simplified wrapper package around Go flag package which returns a map of parsed flag values with flag names as keys and flag values as strings You can supply a default value as a second argument go Options() function. See the example below. Defined() method of FlagMap type evaluates to false IF the specified parameter is empty string or does not exist in the FlagMap.

Example usage

package main

import (
	"fmt"
	"github.com/milosgajdos83/flagmap"
)

func init() {
        flagmap.Option("foo1", "", "This is a foo1 option")
        flagmap.Option("foo2", "foo2val", "This is a foo2 option")
}

func main() {
	options := flagmap.Parse()

	fmt.Printf("Options: %v\n", options)
        fmt.Printf("Just foo2: %v\n", options["foo2"])
}

Once built, you can test the above code like this:

$ ./yourbinary -foo2="test2"
Options: map[foo1: foo2:test2]
foo1 defined: false
