Unmarshal table/section

[bogdan-the-great]

Hi, I don't understand how can I unmarshal values from a table.

[values]
value1 = 2
value2 = "two"
value3 = 0.2

This snippet only unmarshals my file when it doesn't have a table (values) in it

package main

import (
	"fmt"
	"log"
	"os"

	"github.com/pelletier/go-toml/v2"
)

type Config struct {
    Value1 int
    Value2 string
    Value3 float64
}

func main() {
    var cfg Config

    data, err := os.ReadFile("test.toml")
    if err != nil {
        log.Fatal(err)
    }

    err = toml.Unmarshal(data, &cfg)
    if err != nil {
        panic(err)
    }

    fmt.Println(cfg.Value1)
    fmt.Println(cfg.Value2)
    fmt.Println(cfg.Value3)
}

I know that I'm doing something wrong with the struct declaration but don't know what. I have searched for similar issues, but i don't really understand them e.g. #960.

Okay I figured it out. You need to wrap it all in another struct, as follows:

package main

import (
	"fmt"
	"log"
	"os"

	"github.com/pelletier/go-toml/v2"
)

type Config struct {
	Values Values "values"
}

type Values struct {
    Value1 int
    Value2 string
    Value3 float64
}

func main() {
    var cfg Config

    data, err := os.ReadFile("test.toml")
    if err != nil {
        log.Fatal(err)
    }

    err = toml.Unmarshal(data, &cfg)
    if err != nil {
        panic(err)
    }

    fmt.Println(cfg.Values.Value1)
    fmt.Println(cfg.Values.Value2)
    fmt.Println(cfg.Values.Value3)
}
