+# TOML parser and encoder library for Golang [![Build Status](https://travis-ci.org/naoina/toml.png?branch=master)](https://travis-ci.org/naoina/toml)
+
+[TOML](https://github.com/toml-lang/toml) parser and encoder library for [Golang](http://golang.org/).
+
+This library is compatible with TOML version [v0.4.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.4.0.md).
+
+## Installation
+
+    go get -u github.com/naoina/toml
+
+## Usage
+
+The following TOML save as `example.toml`.
+
+```toml
+# This is a TOML document. Boom.
+
+title = "TOML Example"
+
+[owner]
+name = "Lance Uppercut"
+dob = 1979-05-27T07:32:00-08:00 # First class dates? Why not?
+
+[database]
+server = "192.168.1.1"
+ports = [ 8001, 8001, 8002 ]
+connection_max = 5000
+enabled = true
+
+[servers]
+
+  # You can indent as you please. Tabs or spaces. TOML don't care.
+  [servers.alpha]
+  ip = "10.0.0.1"
+  dc = "eqdc10"
+
+  [servers.beta]
+  ip = "10.0.0.2"
+  dc = "eqdc10"
+
+[clients]
+data = [ ["gamma", "delta"], [1, 2] ]
+
+# Line breaks are OK when inside arrays
+hosts = [
+  "alpha",
+  "omega"
+]
+```
+
+Then above TOML will mapping to `tomlConfig` struct using `toml.Unmarshal`.
+
+```go
+package main
+
+import (
+    "io/ioutil"

+    "time"

+
+## Mappings
+
+A key and value of TOML will map to the corresponding field.
+The fields of struct for mapping must be exported.
+
+The rules of the mapping of key are following:
+
+#### Exact matching
+
+```toml
+timeout_seconds = 256
+```
+
+```go
+type Config struct {
+	Timeout_seconds int
+}
+```
+
+#### Camelcase matching
+
+```toml
+server_name = "srv1"
+```
+
+```go
+type Config struct {
+	ServerName string
+}
+```
+
+#### Uppercase matching
+
+```toml
+ip = "10.0.0.1"
+```
+
+```go
+type Config struct {
+	IP string
+}
+```
+
+See the following examples for the value mappings.
+
+### String
+
+```toml
+val = "string"
+```
+
+```go
+type Config struct {
+	Val string
+}
+```
+
+### Integer
+
+```toml
+val = 100
+```
+
+```go
+type Config struct {
+	Val int
+}
+```
+
+All types that can be used are following:
+
+* int8 (from `-128` to `127`)
+* int16 (from `-32768` to `32767`)
+* int32 (from `-2147483648` to `2147483647`)
+* int64 (from `-9223372036854775808` to `9223372036854775807`)
+* int (same as `int32` on 32bit environment, or `int64` on 64bit environment)
+* uint8 (from `0` to `255`)
+* uint16 (from `0` to `65535`)
+* uint32 (from `0` to `4294967295`)
+* uint64 (from `0` to `18446744073709551615`)
+* uint (same as `uint` on 32bit environment, or `uint64` on 64bit environment)
+
+### Float
+
+```toml
+val = 3.1415
+```
+
+```go
+type Config struct {
+	Val float32
+}
+```
+
+All types that can be used are following:
+
+* float32
+* float64
+
+### Boolean
+
+```toml
+val = true
+```
+
+```go
+type Config struct {
+	Val bool
+}
+```
+
+### Datetime
+
+```toml
+val = 2014-09-28T21:27:39Z
+```
+
+```go
+type Config struct {
+	Val time.Time
+}
+```
+
+### Array
+
+```toml
+val = ["a", "b", "c"]
+```
+
+```go
+type Config struct {
+	Val []string
+}
+```
+
+Also following examples all can be mapped:
+
+```toml
+val1 = [1, 2, 3]
+val2 = [["a", "b"], ["c", "d"]]
+val3 = [[1, 2, 3], ["a", "b", "c"]]
+val4 = [[1, 2, 3], [["a", "b"], [true, false]]]
+```
+
+```go
+type Config struct {
+	Val1 []int
+	Val2 [][]string
+	Val3 [][]interface{}
+	Val4 [][]interface{}
+}
+```
+
+### Table
+
+```toml
+[server]
+type = "app"
+
+  [server.development]
+  ip = "10.0.0.1"
+
+  [server.production]
+  ip = "10.0.0.2"
+```
+
+```go
+type Config struct {
+	Server map[string]Server
+}
+
+type Server struct {
+	IP string
+}
+```
+
+You can also use the following struct instead of map of struct.
+
+```go
+type Config struct {
+	Server struct {
+		Development Server
+		Production Server
+	}
+}
+
+type Server struct {
+	IP string
+}
+```
+
+### Array of Tables
+
+```toml
+[[fruit]]
+  name = "apple"
+
+  [fruit.physical]
+    color = "red"
+    shape = "round"
+
+  [[fruit.variety]]
+    name = "red delicious"
+
+  [[fruit.variety]]
+    name = "granny smith"
+
+[[fruit]]
+  name = "banana"
+
+  [[fruit.variety]]
+    name = "plantain"
+```
+
+```go
+type Config struct {
+	Fruit []struct {
+		Name string
+		Physical struct {
+			Color string
+			Shape string
+		}
+		Variety []struct {
+			Name string
+		}
+	}
+}
+```
+
+### Using the `encoding.TextUnmarshaler` interface
+
+Package toml supports `encoding.TextUnmarshaler` (and `encoding.TextMarshaler`). You can
+use it to apply custom marshaling rules for certain types. The `UnmarshalText` method is
+called with the value text found in the TOML input. TOML strings are passed unquoted.
+
+```toml
+duration = "10s"
+```
+
+```go
+import time
+
+type Duration time.Duration
+
+// UnmarshalText implements encoding.TextUnmarshaler
+func (d *Duration) UnmarshalText(data []byte) error {
+    duration, err := time.ParseDuration(string(data))
+    if err == nil {
+        *d = Duration(duration)
+    }
+    return err
+}
+
+// MarshalText implements encoding.TextMarshaler
+func (d Duration) MarshalText() ([]byte, error) {
+    return []byte(time.Duration(d).String()), nil
+}
+
+type ConfigWithDuration struct {
+    Duration Duration
+}
+```
+### Using the `toml.UnmarshalerRec` interface
+
+You can also override marshaling rules specifically for TOML using the `UnmarshalerRec`
+and `MarshalerRec` interfaces. These are useful if you want to control how structs or
+arrays are handled. You can apply additional validation or set unexported struct fields.
+
+Note: `encoding.TextUnmarshaler` and `encoding.TextMarshaler` should be preferred for
+simple (scalar) values because they're also compatible with other formats like JSON or
+YAML.
+
+[See the UnmarshalerRec example](https://godoc.org/github.com/naoina/toml/#example_UnmarshalerRec).
+
+### Using the `toml.Unmarshaler` interface
+
+If you want to deal with raw TOML syntax, use the `Unmarshaler` and `Marshaler`
+interfaces. Their input and output is raw TOML syntax. As such, these interfaces are
+useful if you want to handle TOML at the syntax level.
+
+[See the Unmarshaler example](https://godoc.org/github.com/naoina/toml/#example_Unmarshaler).
