goconfig [![Build Status](https://drone.io/github.com/Unknwon/goconfig/status.png)](https://drone.io/github.com/Unknwon/goconfig/latest) [![Go Walker](http://gowalker.org/api/v1/badge)](http://gowalker.org/github.com/Unknwon/goconfig) [![](http://gocover.io/_badge/github.com/Unknwon/goconfig)](http://gocover.io/github.com/Unknwon/goconfig)
========
[中文文档](README_ZH.md)
Code Convention: based on [Go Code Convention](https://github.com/Unknwon/go-code-convention).
## About
Package goconfig is a easy-use, comments-support configuration file parser for the Go Programming Language, which provides a structure similar to what you would find on Microsoft Windows INI files.
The configuration file consists of sections, led by a `[section]` header and followed by `name:value` or `name=value` entries. Note that leading whitespace is removed from values. The optional values can contain format strings which refer to other values in the same section, or values in a special DEFAULT section. Comments are indicated by ";" or "#"; comments may begin anywhere on a single line.
## Features
- It simplified operation processes, easy to use and undersatnd; therefore, there are less chances to have errors.
- It uses exactly the same way to access a configuration file as you use Windows APIs, so you don't need to change your code style.
- It supports read recursion sections.
- It supports auto increment of key.
- It supports **READ** and **WRITE** configuration file with comments each section or key which all the other parsers don't support!!!!!!!
- It supports get value through type bool, float64, int, int64 and string, methods that start with "Must" means ignore errors and get zero-value if error occurs, or you can specify a default value.
- It's able to load multiple files to overwrite key values.
## Installation
go get github.com/Unknwon/goconfig
Or
gopm get github.com/Unknwon/goconfig
## API Documentation
[Go Walker](http://gowalker.org/github.com/Unknwon/goconfig).
## Example
Please see [conf.ini](testdata/conf.ini) as an example.
### Usage
- Function `LoadConfigFile` load file(s) depends on your situation, and return a variable with type `ConfigFile`.
- `GetValue` gives basic functionality of getting a value of given section and key.
- Methods like `Bool`, `Int`, `Int64` return corresponding type of values.
- Methods start with `Must` return corresponding type of values and returns zero-value of given type if something goes wrong.
- `SetValue` sets value to given section and key, and inserts somewhere if it does not exist.
- `DeleteKey` deletes by given section and key.
- Finally, `SaveConfigFile` saves your configuration to local file system.
- Use method `Reload` in case someone else modified your file(s).
- Methods contains `Comment` help you manipulate comments.
## More Information
- All characters are CASE SENSITIVE, BE CAREFULL!

goconfig [![Build Status](https://drone.io/github.com/Unknwon/goconfig/status.png)](https://drone.io/github.com/Unknwon/goconfig/latest) [![Go Walker](http://gowalker.org/api/v1/badge)](http://gowalker.org/github.com/Unknwon/goconfig)
========
本库已被 [《Go名库讲解》](https://github.com/Unknwon/go-rock-libraries-showcases/tree/master/lectures/01-goconfig) 收录讲解，欢迎前往学习如何使用！
编码规范：基于 [Go 编码规范](https://github.com/Unknwon/go-code-convention)
## 关于
包 goconfig 是一个易于使用，支持注释的 Go 语言配置文件解析器，该文件的书写格式和 Windows 下的 INI 文件一样。
配置文件由形为 `[section]` 的节构成，内部使用 `name:value` 或 `name=value` 这样的键值对；每行开头和尾部的空白符号都将被忽略；如果未指定任何节，则会默认放入名为 `DEFAULT` 的节当中；可以使用 “;” 或 “#” 来作为注释的开头，并可以放置于任意的单独一行中。
## 特性
- 简化流程，易于理解，更少出错。
- 提供与 Windows API 一模一样的操作方式。
- 支持读取递归节。
- 支持自增键名。
- 支持对注释的 **读** 和 **写** 操作，其它所有解析器都不支持！！！！
- 可以直接返回 bool, float64, int, int64 和 string 类型的值，如果使用 “Must” 开头的方法，则一定会返回这个类型的一个值而不返回错误，如果错误发生则会返回零值。
- 支持加载多个文件来重写值。
## 安装
go get github.com/Unknwon/goconfig
或
gopm get github.com/Unknwon/goconfig
## API 文档
[Go Walker](http://gowalker.org/github.com/Unknwon/goconfig).
## 示例
请查看 [conf.ini](testdata/conf.ini) 文件作为使用示例。
### 用例
- 函数 `LoadConfigFile` 加载一个或多个文件，然后返回一个类型为 `ConfigFile` 的变量。
- `GetValue` 可以简单的获取某个值。
- 像 `Bool`、`Int`、`Int64` 这样的方法会直接返回指定类型的值。
- 以 `Must` 开头的方法不会返回错误，但当错误发生时会返回零值。
- `SetValue` 可以设置某个值。
- `DeleteKey` 可以删除某个键。
- 最后，`SaveConfigFile` 可以保持您的配置到本地文件系统。
- 使用方法 `Reload` 可以重载您的配置文件。
