go-toml

Go library for the TOML format.

This library supports TOML version v1.0.0-rc.3

Development status

ℹ️ Consider go-toml v2!

The next version of go-toml is in active development, and nearing completion.

Though technically in beta, v2 is already more tested, fixes bugs, and much faster. If you only need reading and writing TOML documents (majority of cases), those features are implemented and the API unlikely to change.

The remaining features will be added shortly. While pull-requests are welcome on v1, no active development is expected on it. When v2.0.0 is released, v1 will be deprecated.

Features

Go-toml provides the following features for using data parsed from TOML documents:

• Load TOML documents from files and string data
• Easily navigate TOML structure using Tree
• Marshaling and unmarshaling to and from data structures
• Line & column position data for all parsed elements
• Query support similar to JSON-Path
• Syntax errors contain line and column numbers

Import

import "github.com/pelletier/go-toml"

Usage example

Read a TOML document:

config, _ := toml.Load(`
[postgres]
user = "pelletier"
password = "mypassword"`)
// retrieve data directly
user := config.Get("postgres.user").(string)

// or using an intermediate object
postgresConfig := config.Get("postgres").(*toml.Tree)
password := postgresConfig.Get("password").(string)

Or use Unmarshal:

type Postgres struct {
    User     string
    Password string
}
type Config struct {
    Postgres Postgres
}

doc := []byte(`
[Postgres]
User = "pelletier"
Password = "mypassword"`)

config := Config{}
toml.Unmarshal(doc, &config)
fmt.Println("user=", config.Postgres.User)

Or use a query:

// use a query to gather elements without walking the tree
q, _ := query.Compile("$..[user,password]")
results := q.Execute(config)
for ii, item := range results.Values() {
    fmt.Printf("Query result %d: %v\n", ii, item)
}

Documentation

The documentation and additional examples are available at pkg.go.dev.

Tools

Go-toml provides three handy command line tools:

• tomll: Reads TOML files and lints them.

  go install github.com/pelletier/go-toml/cmd/tomll
  tomll --help
  

• tomljson: Reads a TOML file and outputs its JSON representation.

  go install github.com/pelletier/go-toml/cmd/tomljson
  tomljson --help
  

• jsontoml: Reads a JSON file and outputs a TOML representation.

  go install github.com/pelletier/go-toml/cmd/jsontoml
  jsontoml --help
  

Docker image

Those tools are also available as a Docker image from dockerhub. For example, to use tomljson:

docker run -v $PWD:/workdir pelletier/go-toml tomljson /workdir/example.toml

Only master (latest) and tagged versions are published to dockerhub. You can build your own image as usual:

docker build -t go-toml .

Fuzzing

The script ./fuzz.sh is available to run go-fuzz on go-toml.

Versioning

Go-toml follows Semantic Versioning. The supported version of TOML is indicated at the beginning of this document. The last two major versions of Go are supported (see Go Release Policy).
