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 + +## 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. +- `LoadFromReader` allows loading data without an intermediate file. +- `SaveConfigData` added, which writes configuration to an arbitrary writer. +- `ReloadData` allows to reload data from memory. + +Note that you cannot mix in-memory configuration with on-disk configuration. + +## More Information + +- All characters are CASE SENSITIVE, BE CAREFUL! + +## Credits + +- [goconf](http://code.google.com/p/goconf/) +- [robfig/config](https://github.com/robfig/config) +- [Delete an item from a slice](https://groups.google.com/forum/?fromgroups=#!topic/golang-nuts/lYz8ftASMQ0) + +## License + +This project is under Apache v2 License.
