macreader

// testFile is a CSV file with CR line endings.
testFile := bytes.NewBufferString("a,b,c\r1,2,3\r").Bytes()

// First try reading the csv file the normal way.
// The CSV reader doesn't recognize the '\r' line ending.
r1 := csv.NewReader(bytes.NewReader(testFile))
lines1, err := r1.ReadAll()
if err != nil {
	fmt.Println(err)
}
fmt.Printf("Without macreader: %#v\n", lines1)

// Now try reading the csv file using macreader.
// It should work as expected.
r2 := csv.NewReader(New(bytes.NewReader(testFile)))
lines2, err := r2.ReadAll()

Output:

Without macreader: [][]string{[]string{"a", "b", "c\r1", "2", "3"}}
With macreader: [][]string{[]string{"a", "b", "c"}, []string{"1", "2", "3"}}
