goini - A no-dependence builtin-like ini config file parser

Should work with most type with encoding.TextUnmarshaler and encoding.TextMarshaler interfaces.

Install

go get -u github.com/wildwest-productions/goini

Example

Short:

type myConfig struct {
	Dir1 string `ini:"dir"`
	Runs int    `ini:"runs"`
}

iniBytes, err := ioutil.ReadFile("somefile.ini")

c := &myConfig{}
err := goini.Unmarshal(iniBytes, &c)

Full example:

package main

import (
	"fmt"
	"os"

	"github.com/wildwest-productions/goini"
)

type testStruct struct {
	ConfigStr     string     `ini:"hello"`
	ConfigInt     int        `ini:"bar"`
	Val           string     `ini:"t"`
	Hello         subStruct  `ini:"sector"`
	SystemEnabled bool       `ini:"sys_enable"`
	Command       subStruct2 `ini:"command"`
}

type subStruct struct {
	Bar           string `ini:"hello"`
	SystemEnabled bool   `ini"sys_enable"`
}

type subStruct2 struct {
	Command string `ini:"command"`
	Runs    int    `ini:"runs"`
}

func main() {
	s := &testStruct{}

	iniData := []byte(
		`
hello=world
bar = 2
t=hi
sys_enable = true

[command]
command = echo hello
runs = 42

[sector]
hello=world-world
sys_enable = NO

`)

	err := goini.Unmarshal(iniData, &s)
	if err != nil {
		fmt.Printf("Failed to unmarshal ini: %s\n", err)
		os.Exit(1)
	}

	fmt.Printf("Converted ini:\n%s\n", string(iniData))

	fmt.Printf("Into struct: %+v\n", s)
}

Features

• Supports comments, both # and ;
• Define with and without whitespace (foo=bar and foo = bar)
• Supports common value types (bool, int, float32, float64, string) and all (most) custom types with encoding.TextUnmarshaler and encoding.TextMarshaler interfaces
• No dependencies (other then builtins)

Limitations

There are some limitations:

• sub-struct pointers will not work (willfix)
• cannot unmarshal into a map (wontfix)
• comments will not be perserved when unmarshaling/marshaling (willfix)
