This question already has an answer here:

• Go Unmarshaling YAML into struct 2 answers

Im trying to convert a yaml data into a struct and print it. The output I get for this program is empty.

package main

import (
"fmt"

"gopkg.in/yaml.v2"
)

type example struct {
    variable1 string
    variable2 string
}

func main() {
    var a example
    yaml.Unmarshal([]byte("variable1: asd
variable2: sdcs"), &a)
    fmt.Println(a.variable1)
}

</div>

Answer 1

The documentation for Unmarshal states that

Struct fields are only unmarshalled if they are exported (have an upper case first letter) and are unmarshalled using the field name lowercased as the default key.

So capitalizing your struct elements is the right thing to do.

type example struct {
    Variable1 string
    Variable2 string
}
