Parsing Configuration Files

The config module is used for parsing configuration files, inspired by database/sql. It supports ini, json, xml and yaml files. You can install it by:

go get

If you want to parse xml or yaml, you should first install:

go get -u

and then import:

import _ ""

Basic Usage

Initialize a parser object:

iniconf, err := NewConfig("ini", "testini.conf")
if err != nil {

Get data from parser:


Parser methods

Here are the parser’s methods:

  • Setting values:
    • Set(key, val string) error
    • SaveConfigFile(filename string) error
  • Getting values:
    • String(key string) string
    • Strings(key string) []string
    • Int(key string) (int, error)
    • Int64(key string) (int64, error)
    • Bool(key string) (bool, error)
    • Float(key string) (float64, error)
    • DIY(key string) (interface{}, error)
    • GetSection(section string) (map[string]string, error)
  • Getting values or a default value:
    • DefaultString(key string, defaultval string) string
    • DefaultStrings(key string, defaultval []string) []string
    • DefaultInt(key string, defaultval int) int
    • DefaultInt64(key string, defaultval int64) int64
    • DefaultBool(key string, defaultval bool) bool
    • DefaultFloat(key string, defaultval float64) float64

Configuration sections

The ini file supports configuration sections. You can get values inside a section by using section::key.

For example:

key1 = "asta"
key2 = "xie"

You can use iniconf.String("demo::key2") to get the value.
