How do I encode a struct to/from TOML in Go?

In Go, you can easily work with TOML files by using the github.com/BurntSushi/toml library. This library allows encoding and decoding of structs to TOML format.

Example Code


import (
    "encoding/json"
    "fmt"
    "log"

    "github.com/BurntSushi/toml"
)

// Config is a struct that represents the configuration structure
type Config struct {
    Title   string `toml:"title"`
    Owner   Owner  `toml:"owner"`
}

// Owner is a nested struct for owner details
type Owner struct {
    Name    string `toml:"name"`
    DOB     string `toml:"dob"`
}

// Encode a struct to TOML
func encodeToml(cfg Config) (string, error) {
    var buf []byte
    if err := toml.NewEncoder(&buf).Encode(cfg); err != nil {
        return "", err
    }
    return string(buf), nil
}

// Decode TOML to a struct
func decodeToml(data string) (Config, error) {
    var cfg Config
    if _, err := toml.Decode(data, &cfg); err != nil {
        return cfg, err
    }
    return cfg, nil
}

func main() {
    cfg := Config{
        Title: "TOML Example",
        Owner: Owner{
            Name: "John Doe",
            DOB:  "1985-01-01",
        },
    }

    // Encode to TOML
    tomlData, err := encodeToml(cfg)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(tomlData)

    // Decode from TOML
    var newCfg Config
    newCfg, err = decodeToml(tomlData)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Printf("Decoded Config: %+v\n", newCfg)
}
