`INI` contents parser by Golang, `INI` config data management.
> **[中文说明](README.zh-CN.md)**
## Features
- Easy to use(get: `Int` `Int64` `Bool` `String` `StringMap` ..., set: `Set`)
- Support multi file, data load
- Support for decode data to struct
- Support data override merge
- Support parse ENV variable
- Support comments start with `;` `#`, multi line comments `/* .. */`
- Support multi line value with `"""` or `'''`
- Complete unit test(coverage > 90%)
- Support variable reference, default compatible with Python's configParser format `%(VAR)s`
### [Parser](./parser)
Package `parser` is a Parser for parse INI format content to golang data
### [Dotenv](./dotenv)
Package `dotenv` that supports importing ENV data from files (eg `.env`)
## More formats
If you want more support for file content formats, recommended use `gookit/config`
- [gookit/config](https://github.com/gookit/config) - Support multi formats: `JSON`(default), `INI`, `YAML`, `TOML`, `HCL`
## GoDoc
- [godoc](https://pkg.go.dev/github.com/gookit/ini)
## Install
```bash
go get github.com/gookit/ini/v2
```
## Usage
- example data(`testdata/test.ini`):
```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
```go
package main
import (
"github.com/gookit/ini/v2"
)
// 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
```go
age := ini.Int("age")
fmt.Print(age) // 100
```
- Get bool
```go
val := ini.Bool("debug")
fmt.Print(val) // true
```
- Get string
```go
name := ini.String("name")
fmt.Print(name) // inhere
```
- Get section data(string map)
```go
val := ini.StringMap("sec1")
fmt.Println(val)
// map[string]string{"key":"val0", "some":"change val", "stuff":"things", "newK":"newVal"}
```
- Value is ENV var
```go
value := ini.String("shell")
fmt.Printf("%q", value) // "/bin/zsh"
```
- **Get value by key path**
```go
value := ini.String("sec1.key")
fmt.Print(value) // val0
```
- Use var refer
```go
value := ini.String("sec1.varRef")
fmt.Printf("%q", value) // "val in default section"
```
- Set new value
```go
// set value
ini.Set("name", "new name")
name = ini.String("name")
fmt.Printf("%q", name) // "new name"
```
## Mapping data to struct
```go
type User struct {
Name string
Age int
}
user := &User{}
ini.MapStruct(ini.DefSection(), user)
dump.P(user)
```
Special, mapping all data:
```go
ini.MapStruct("", ptr)
```
## Variable reference resolution
```ini
[portal]
url = http://%(host)s:%(port)s/api
host = localhost
port = 8080
```
If variable resolution is enabled，will parse `%(host)s` and replace it：
```go
cfg := ini.New()
// enable ParseVar
cfg.WithOptions(ini.ParseVar)
fmt.Print(cfg.MustString("portal.url"))
// OUT:
// http://localhost:8080/api
```
## Available options
```go
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 for default instance:
```go
ini.WithOptions(ini.ParseEnv,ini.ParseVar)
```
Setting options with new instance:
```go
cfg := ini.New()
cfg.WithOptions(ini.ParseEnv, ini.ParseVar, func (opts *Options) {
opts.SectionSep = ":"
opts.DefSection = "default"
})
```
## Dotenv
Package `dotenv` that supports importing data from files (eg `.env`) to ENV
### Usage
```go
err := dotenv.Load("./", ".env")
// err := dotenv.LoadExists("./", ".env")
val := dotenv.Get("ENV_KEY")
// Or use
// val := os.Getenv("ENV_KEY")
// get int value
intVal := dotenv.Int("LOG_LEVEL")
// with default value
val := dotenv.Get("ENV_KEY", "default value")
```
