struct with field name starting with `N` fails to read data

[surajssd]

Here is a code snippet that I am running:

$ cat non.go 
package main

import (
        "fmt"
        "log"

        "github.com/ghodss/yaml"
)

type C struct {
        M int `yaml:"M"`
        N int `yaml:"N"`
}

func main() {
        d := []byte(`
M: 1
N: 2
`)

        var c C
        err := yaml.Unmarshal(d, &c)
        if err != nil {
                log.Fatalln(err)
        }
        fmt.Printf("%#v\n", c)

}

Once I run it:

$ go run non.go 
main.C{M:1, N:0}

In YAML the key can be a value, and a boolean can represented with (n|N|y|Y). During parsing the type appears to be identifying N as a boolean type so when it compares the tag to the key being parsed it is comparing "false" to "N". I believe you can fix this by quoting your key in the file being parsed:

        d := []byte(`
M: 1
"N": 2
`)
