ini
ini parse by golang. ini config data manage
- Easy to use(get:
IntBoolStringStringMap, set:SetIntSetBoolSetString...) - Support multi file, data load
- Support data override merge
- Support parse ENV variable
- Support variable reference, default compatible with Python's configParser format
%(VAR)s - Complete unit test(coverage > 90%)
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
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
config, err := ini.LoadExists("testdata/test.ini", "not-exist.ini")
if err != nil {
panic(err)
}
// load more, will override prev data by key
err = config.LoadStrings(`
age = 100
[sec1]
newK = newVal
some = change val
`)
// fmt.Printf("%v\n", config.Data())
}
Read data
- get integer
age, ok := config.Int("age")
fmt.Print(ok, age) // true 100
- get bool
val, ok := config.Bool("debug")
fmt.Print(ok, age) // true true
- get string
name, ok := config.String("name")
fmt.Print(ok, name) // true inhere
- get section data(string map)
val, ok := config.StringMap("sec1")
fmt.Println(ok, val)
// true map[string]string{"key":"val0", "some":"change val", "stuff":"things", "newK":"newVal"}
- value is ENV var
value, ok := config.String("shell")
fmt.Printf("%v %q", ok, value) // true "/bin/zsh"
- get value by key path
value, ok := config.String("sec1.key")
fmt.Print(ok, value) // true val0
- use var refer
value, ok := config.String("sec1.varRef")
fmt.Printf("%v %q", ok, value) // true "val in default section"
- setting new value
// set value
config.Set("name", "new name")
name, ok = config.String("name")
fmt.Printf("%v %q", ok, value) // true "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"
})

Overview ¶
Package ini is a ini config file/data manage implement
Source code and other details for the project are available at GitHub:

INI parser is: https://github.com/gookit/ini/parser
Example ¶
// config, err := LoadFiles("testdata/tesdt.ini")
// LoadExists will ignore not exists file
config, err := LoadExists("testdata/test.ini", "not-exist.ini")
if err != nil {
panic(err)
}
// load more, will override prev data by key
_ = config.LoadStrings(`
age = 100
[sec1]
newK = newVal
some = change val
`)
// fmt.Printf("%v\n", config.Data())
iv, ok := config.Int("age")
fmt.Printf("get int\n - ok: %v, val: %v\n", ok, iv)
bv, ok := config.Bool("debug")
fmt.Printf("get bool\n - ok: %v, val: %v\n", ok, bv)
name, ok := config.String("name")
fmt.Printf("get string\n - ok: %v, val: %v\n", ok, name)
sec1, ok := config.StringMap("sec1")
fmt.Printf("get section\n - ok: %v, val: %#v\n", ok, sec1)
str, ok := config.String("sec1.key")
fmt.Printf("get sub-value by path 'section.key'\n - ok: %v, val: %s\n", ok, str)
// can parse env name(ParseEnv: true)
fmt.Printf("get env 'envKey' val: %s\n", config.MustString("shell"))
fmt.Printf("get env 'envKey1' val: %s\n", config.MustString("noEnv"))
// set value
_ = config.Set("name", "new name")
name, ok = config.String("name")
fmt.Printf("set string\n - ok: %v, val: %v\n", ok, name)
// export data to file
// _, err = config.WriteToFile("testdata/export.ini")
// if err != nil {
// panic(err)
// }
// Out:
// get int
// - ok: true, val: 100
// get bool
// - ok: true, val: true
// get string
// - ok: true, val: inhere
// get section
// - ok: true, val: map[string]string{"stuff":"things", "newK":"newVal", "key":"val0", "some":"change val"}
// get sub-value by path 'section.key'
// - ok: true, val: val0
// get env 'envKey' val: /bin/zsh
// get env 'envKey1' val: defValue
// set string
// - ok: true, val: new name
