parse args from a string by splitting on spaces, leaving quoted strings together as one arg

quoted-parse.go

package main

import (
	"fmt"
)

func parse(line string) ([]string, error) {
	args := []string{}
	quoted := false

	newArg := []rune{}
	for i, r := range line {
		s := string(r)

		if s == ` ` && quoted == false {
			args = append(args, string(newArg))
			newArg = newArg[:0]
		} else {
			if s == `"` {
				quoted = !quoted
			}
			newArg = append(newArg, r)
			if i+1 == len(line) {
				args = append(args, string(newArg))
			}
		}
	}

	return args, nil
}

func main() {
	p1, _ := parse(`gdfs sgfd saf "sdf dfg"`)
	p2, _ := parse(`gdfs sgfd "sdf dfg" saf`)
	p3, _ := parse(`"sdf dfg" gdfs sgfd saf`)

	fmt.Println(p1)
	fmt.Println(p2)
	fmt.Println(p3)
}
