## Development status

**ℹ️ Consider go-toml v2!**

The next version of go-toml is in [active development][v2-dev], and
[nearing completion][v2-map].

Though technically in beta, v2 is already more tested, [fixes bugs][v1-bugs],
and [much faster][v2-bench]. 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](query/)
* Syntax errors contain line and column numbers

## Import

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

## Usage example

Read a TOML document:

```go
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:

```go
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:

```go
// 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](https://pkg.go.dev/github.com/pelletier/go-toml).

## 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](https://hub.docker.com/r/pelletier/go-toml). 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 .
```

## Contribute

Feel free to report bugs and patches using GitHub's pull requests system on
[pelletier/go-toml](https://github.com/pelletier/go-toml). Any feedback would be
much appreciated!

### Run tests

`go test ./...`

### Fuzzing

The script `./fuzz.sh` is available to
run [go-fuzz](https://github.com/dvyukov/go-fuzz) on go-toml.

## Versioning

Go-toml follows [Semantic Versioning](http://semver.org/). The supported version
of [TOML](https://github.com/toml-lang/toml) is indicated at the beginning of
this document. The last two major versions of Go are supported
