The INI Parser & Reader Writer Library is a fast and easy-to-use library for parsing and manipulating INI files in the Go programming language. It provides functionality to read INI files from both byte slices and files, supports real-time file monitoring, and offers options to unmarshal INI data into Go structs, marshal data to JSON, and write data back to files.
- Read by []byte: The library allows you to parse INI data stored in a byte slice.
- Read by file: You can also read INI data directly from a file.
- Real-time file monitoring: The library supports file monitoring, allowing you to observe changes in INI files without the need for manual reloading.
- Unmarshal to Struct: It provides the ability to map INI data to Go structs, making it convenient to work with structured data.
- Marshal to JSON: You can easily convert INI data to JSON format using the library's marshal functionality.
- Write to File: The library allows you to write INI data back to files, preserving the original file format.
