Golang读取文件回车

Hi i have a implementation to read a file Line Feed, but it does not work to Carriage Return files the implementation is:

file, err := os.Open(filePath)
    if err != nil {
        ross := int32(1)
        fileValidation = append(fileValidation, p.createPharmacyPanelLoaderResultErr(pharmacyPanel, &ross, err.Error(), err.Error()))
        return nil, fileValidation, int32(0)
    }

scanner := bufio.NewScanner(file)
for i := 0; scanner.Scan(); i++ {
 line := scanner.Text()
}

i want to transform this function to can work with both Carriage Return and Line Feed

I took the ScanLines function from the source code and changed it so it works with but now it will only work with and not or

package main

import (
    "bufio"
    "bytes"
    "fmt"
    "os"
)

func ScanLinesWithCR(data []byte, atEOF bool) (advance int, token []byte, err error) {
    if atEOF && len(data) == 0 {
        return 0, nil, nil
    }
    if i := bytes.IndexByte(data, ''); i >= 0 {
        // We have a full newline-terminated line.
        return i + 1, data[0:i], nil
    }
    // If we're at EOF, we have a final, non-terminated line. Return it.
    if atEOF {
        return len(data), data, nil
    }
    // Request more data.
    return 0, nil, nil
}

func main() {
    f, _ := os.Open("test.txt")
    defer f.Close()
    scanner := bufio.NewScanner(f)
    scanner.Split(ScanLinesWithCR)
    for scanner.Scan() {
        fmt.Println(">", scanner.Text())
    }
}
