inifile-cpp
A simple, header-only C++ library for parsing and writing INI configuration files.
What is inifile-cpp?
inifile-cpp is a header-only C++ library designed for parsing and writing INI configuration files. It provides a simple API to load, modify, and save INI data, supporting type-safe conversions to native C++ types and custom type extensions. The library solves the problem of managing configuration files in C++ projects without relying on external dependencies.
C++ developers who need a lightweight, dependency-free solution for reading and writing INI files in their applications, such as those working on desktop software, games, or embedded systems.
Developers choose inifile-cpp for its simplicity, ease of integration as a single-header library, and flexibility in handling custom data types. It offers a clean, intuitive API that reduces boilerplate code compared to writing custom INI parsers.
Overview
A header-only and easy to use Ini file parser for C++.
Use Cases
Best For
- Parsing configuration files in C++ desktop applications
- Managing game settings or save files in INI format
- Embedded systems requiring lightweight configuration management
- Prototyping projects where quick INI file support is needed
- Educational purposes to learn about file parsing in C++
- Extending INI parsing with custom data types like vectors
Not Ideal For
- Projects requiring strict INI specification compliance with comment preservation or escape sequences
- Applications needing hierarchical or nested configuration data beyond flat INI sections
- Teams that prefer libraries with built-in schema validation or extensive error reporting
- Real-time systems where exception-based error handling could introduce unwanted overhead
Pros & Cons
Pros
As a single-header library, it can be included directly in C++ projects without build dependencies or linking, simplifying setup as shown in the README's installation options.
The `as()` method supports native C++ types like bool, int, and std::string, reducing manual parsing errors and boilerplate code for common data types.
Developers can add support for custom data types, such as vectors, by implementing specialized `ini::Convert` functors, enabling flexible configuration handling beyond basic types.
Load and save INI data from any std::istream or std::ostream, allowing integration with files, strings, or other streams for versatile input/output scenarios.
Cons
The library lacks support for advanced INI features like comment preservation, section nesting, or escape sequences, which are essential for complex or standardized configurations.
Errors, such as duplicate fields when disallowed, throw exceptions, which may not align with projects that avoid exceptions for performance or safety reasons.
Adding support for custom types requires manual implementation of `ini::Convert` functors, which can be error-prone and increase development time, as seen in the vector example.
