pw: parse words

This is for parsing a string into a set of words. For Example:

import (
	pw "github.com/pschlump/pw3"
)

/* ... */

func ParseLineIntoWords(line string) []string {
	Pw := pw.NewParseWords()
	Pw.SetOptions("C", false, false)
	Pw.SetLine(line)
	rv := Pw.GetWords()
	return rv
}

Will take a line like this one and return an array of words.

Examples using the above code.

	s := `set aa "{\"ab\":123}"`
	words := ParseLineIntoWords(s)
	fmt.Printf ( "%s\n", words )

Outputs in (length 3)

[set aa {"ab":123}]

2nd Example

Example using CLI input and parsing multiple lines into words.

package main

import (
	"bufio"
	"fmt"
	"log"
	"os"

	pw "github.com/pschlump/pw3"
)

func main() {
	Pw := pw.NewParseWords()
	// Pw.SetOptions("C", false, false)  -- these are the default opsions, so skip

	scanner := bufio.NewScanner(os.Stdin)
	line_no := 0
	for scanner.Scan() {
		line_no++
		line := scanner.Text()

		Pw.SetLine(line)
		words := Pw.GetWords()

		fmt.Printf("Words len=%d: %s\n", len(words), words)
	}

	if err := scanner.Err(); err != nil {
		log.Fatal(err)
	}
}
