just testing to sort by number extracted from string with regexp

sorting-with-regexp.go

package main

import (
	"fmt"
	"sort"
	"regexp"
	"strconv"
)

type M struct {
  Name string
}

func main() {
  data := []M {M{"quickstart-1"}, M{"quickstart-10"}, M{"quickstart-0"}, M{"quickstart-2"}, M{"quickstart-3"}}
  pattern := regexp.MustCompile(`([0-9]+)$`) // number at the end
  sort.SliceStable(data, func(i, j int) bool {
    number1, _ := strconv.Atoi(pattern.FindStringSubmatch(data[i].Name)[1])
    number2, _ := strconv.Atoi(pattern.FindStringSubmatch(data[j].Name)[1])
    return number1 < number2
    // return i < j
  })
  fmt.Println(data)
}
