[Bug?] Struct of Ints Fails to Unmarshal Second Field

[neilwhitlow]

Apologies if I'm missing something obvious as I'm still relatively new with Go, so highly possible this is user error.

Trying to follow the simple Unmarshal example with a struct that has 2 int fields and the second one is always zero.

I have tried with all positive integers in the second column of the csv and it makes no difference, I'm always seeing zero for the mod field.

Code

Link to Playground

type ScoreModifer struct {
    Score    int `csv:"score"`
    Modifier int `csv:"mod"`
}

var csvInput = []byte(`
score, mod
0, -2
1, -2
2, 0
3, 2
4, 3
`)

func main() {
    var mods []ScoreModifer
    if err := csvutil.Unmarshal(csvInput, &mods); err != nil {
        fmt.Println("error:", err)
    }
    for _, m := range mods {
        fmt.Printf("%+v\n", m)
    }
}

Output

{Score:0 Modifier:0}
{Score:1 Modifier:0}
{Score:2 Modifier:0}
{Score:3 Modifier:0}
{Score:4 Modifier:0}

Expected Output

{Score:0 Modifier:-2}
{Score:1 Modifier:-2}
{Score:2 Modifier:0}
{Score:3 Modifier:2}
{Score:4 Modifier:3}

You have a space in your header and every row on the second column.

This is not being automatically handled. You may want to look into Decoder.NormalizeHeader and Decoder.Map to trim whitespace

Good googly moogly, thanks for this. Cannot believe I didn't try that variation of input.
