# go-toml
Go library for the [TOML](https://github.com/mojombo/toml) format.

## 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](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.Println("Query result %d: %v", ii, item)
}
```
## Documentation
The documentation and additional examples are available at
[godoc.org](http://godoc.org/github.com/pelletier/go-toml).
## 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](https://github.com/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`.
### 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
(see [Go Release Policy](https://golang.org/doc/devel/release.html#policy)).
