Overview

Package stringlist implements a custom "stringlist" flag It accepts comma separated values and repeated flag occurrence. Leading and trailing whitespace will be trimmed.

Usage:

var (
	myFlag stringlist.Value
)

func init() {
	flag.Var(&myFlag, "myflag", "a list of strings")
}

Or:

var (
	myFlag = stringlist.Flag("myflag", "a list of strings")
)

func foo() {
	for _, i = range *myFlag {
		// note: you need to dereference the slice
	}
}

If you invoke it with:

--myflag a,b --myflag c --myflag "c, d"

myFlag will contain: []string{"a", "b", "c", "d"}
