【小小小组件】将文本逐行写入字符组

快速导入本地文本字典至字符组

package main

import (
   "os"
   "log"
   "fmt"
   "bufio"
   "reflect"
)

func main() {
   newArray,_ := fileToArray("dict.txt")
   fmt.Println(reflect.TypeOf(newArray))
   fmt.Println(newArray[0:3])
}

func fileToArray(dict string) ([]string,error){
   file, err := os.Open(dict)
   if err != nil {
      log.Printf("Cannot open text file: %s, err: [%v]", dict, err)
      return nil,err
   }
   defer file.Close()

   scanner := bufio.NewScanner(file)
   var line string
   var tmp []string
   for scanner.Scan() {
      line = scanner.Text()
      //添加进组
      tmp = append(tmp,line)
      //do_your_function(line)
   }

   if err := scanner.Err(); err != nil {
      log.Printf("Cannot scanner text file: %s, err: [%v]", dict, err)
      return nil,err
   }
   return tmp,err
}
