# go-toml
|
|
|
|
Go library for the [TOML](https://github.com/mojombo/toml) format.
|
|
|
|
This library supports TOML version
|
|
[v0.2.0](https://github.com/mojombo/toml/blob/master/versions/toml-v0.2.0.md)
|
|
|
|

|

|
## 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 TomlTree
|
|
* Line & column position data for all parsed elements
|
|
* Query support similar to JSON-Path
|
|
* Syntax errors contain line and column numbers
|
|
|
|
Go-toml is designed to help cover use-cases not covered by reflection-based TOML parsing:
|
|
|
|
* Semantic evaluation of parsed TOML
|
|
* Informing a user of mistakes in the source document, after it has been parsed
|
|
* Programatic handling of default values on a case-by-case basis
|
|
* Using a TOML document as a flexible data-store
|
|
|
|
## Import
|
|
|
|
import "github.com/pelletier/go-toml"
|
|
|
|
## Usage
|
|
|
|
### Example
|
|
|
|
Say you have a TOML file that looks like this:
|
|
|
|
```toml
|
|
[postgres]
|
|
user = "pelletier"
|
|
password = "mypassword"
|
|
```
|
|
|
|
Read the username and password like this:
|
|
|
|
```go
|
|
import (
|
|
"fmt"
|
|
"github.com/pelletier/go-toml"
|
|
)
|
|
|
|
config, err := toml.LoadFile("config.toml")
|
|
if err != nil {
|
|
fmt.Println("Error ", err.Error())
|
|
} else {
|
|
// retrieve data directly
|
|
user := config.Get("postgres.user").(string)
|
|
password := config.Get("postgres.password").(string)
|
|
|
|
// or using an intermediate object
|
|
configTree := config.Get("postgres").(*toml.TomlTree)
|
|
user = configTree.Get("user").(string)
|
|
password = configTree.Get("password").(string)
|
|
fmt.Println("User is ", user, ". Password is ", password)
|
|
|
|
// show where elements are in the file
|
|
fmt.Println("User position: %v", configTree.GetPosition("user"))
|
|
fmt.Println("Password position: %v", configTree.GetPosition("password"))
|
|
|
|
// use a query to gather elements without walking the tree
|
|
results, _ := config.Query("$..[user,password]")
|
|
for ii, item := range results.Values() {
|
|
fmt.Println("Query result %d: %v", ii, item)
|
|
}
|
|
}
|
|
```

|
### 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`.
