ini

INI data parse by golang. INI config data management tool library.

中文说明

• Easy to use(get: Int Int64 Bool String StringMap ..., set: Set)
• Support multi file, data load
• Support data override merge
• Support parse ENV variable
• Complete unit test(coverage > 90%)
• Support variable reference, default compatible with Python's configParser format %(VAR)s

More formats

If you want more support for file content formats, recommended use gookit/config

• gookit/config - Support multi formats: JSON(default), INI, YAML, TOML, HCL

GoDoc

• doc on gowalker
• godoc for github

Usage

• example data(testdata/test.ini):

# comments
name = inhere
age = 50
debug = true
hasQuota1 = 'this is val'
hasQuota2 = "this is val1"
can2arr = val0,val1,val2
shell = ${SHELL}
noEnv = ${NotExist|defValue}
nkey = val in default section

; comments
[sec1]
key = val0
some = value
stuff = things
varRef = %(nkey)s

Load data

package main

import (
	"github.com/gookit/ini"
)

// go run ./examples/demo.go
func main() {
	// config, err := ini.LoadFiles("testdata/tesdt.ini")
	// LoadExists will ignore not exists file
	err := ini.LoadExists("testdata/test.ini", "not-exist.ini")
	if err != nil {
		panic(err)
	}

	// load more, will override prev data by key
	err = ini.LoadStrings(`
age = 100
[sec1]
newK = newVal
some = change val
`)
	// fmt.Printf("%v\n", config.Data())
}

Read data

• Get integer

age := config.Int("age")
fmt.Print(age) // 100

• Get bool

val := config.Bool("debug")
fmt.Print(val) // true

• Get string

name := config.String("name")
fmt.Print(name) // inhere

• Get section data(string map)

val := config.StringMap("sec1")
fmt.Println(val) 
// map[string]string{"key":"val0", "some":"change val", "stuff":"things", "newK":"newVal"}

• Value is ENV var

value := config.String("shell")
fmt.Printf("%q", value)  // "/bin/zsh"

• Get value by key path

value := config.String("sec1.key")
fmt.Print(value) // val0

• Use var refer

value := config.String("sec1.varRef")
fmt.Printf("%q", value) // "val in default section"

• Setting new value

// set value
config.Set("name", "new name")
name = config.String("name")
fmt.Printf("%q", value) // "new name"

Variable reference resolution

[portal] 
url = http://%(host)s:%(port)s/api
host = localhost 
port = 8080

If variable resolution is enabled，will parse %(host)s and replace it：

cfg := ini.New()
// enable ParseVar
cfg.WithOptions(ini.ParseVar)

fmt.Print(cfg.MustString("portal.url"))
// OUT: 
// http://localhost:8080/api 

Available options

type Options struct {
	// set to read-only mode. default False
	Readonly bool
	// parse ENV var name. default True
	ParseEnv bool
	// parse variable reference "%(varName)s". default False
	ParseVar bool

	// var left open char. default "%("
	VarOpen string
	// var right close char. default ")s"
	VarClose string

	// ignore key name case. default False
	IgnoreCase bool
	// default section name. default "__default"
	DefSection string
	// sep char for split key path. default ".", use like "section.subKey"
	SectionSep string
}

• setting options

cfg := ini.New()
cfg.WithOptions(ini.ParseEnv,ini.ParseVar, func (opts *Options) {
	opts.SectionSep = ":"
	opts.DefSection = "default"
})
