go-toml

Go library for the TOML format.

This library supports TOML version v0.4.0

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
• Mashaling 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.Println("Query result %d: %v", ii, item)
}

Documentation

The documentation and additional examples are available at godoc.org.

Tools

Go-toml provides two handy command line tools:

• tomll: Reads TOML files and lint 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
  

Contribute

Feel free to report bugs and patches using GitHub's pull requests system on pelletier/go-toml. Any feedback would be much appreciated!

Run tests

You have to make sure two kind of tests run:

1. The Go unit tests
2. The TOML examples base

You can run both of them using ./test.sh.
