How to integrate Sane C++ Libraries into a CMake project?

Since libraries are distributed as single header files, you can include them directly in your source; however, the README notes you must manually link system libraries like pthread or ws2_32, and define SANE_CPP_IMPLEMENTATION in one .cpp file for implementation.

Sane C++ Libraries vs Boost for cross-platform C++ development?

Sane C++ Libraries focus on minimalism and no stdlib dependency, offering faster compile times and smaller binaries, but Boost provides a more mature, feature-rich ecosystem with broader community support and documentation.

Does Sane C++ Libraries support async I/O on Windows and Linux?

Yes, the Async library provides asynchronous I/O for files, sockets, and processes across both platforms, using native OS APIs as mentioned in the library descriptions, but note it's marked as MVP (yellow) for some features.

What are the performance benefits of using Sane C++ Libraries over standard C++?

Benefits include reduced binary size due to no stdlib overhead, predictable memory usage from the no-allocations policy, and faster compilation from single-file libraries, as outlined in the principles and key features.

How to handle errors without exceptions in Sane C++ Libraries?

Libraries use the SC::Result type from the Foundation library for error handling, returning error codes and requiring manual checks, which is documented in the examples and library pages for robust error management.

Is Sane C++ Libraries suitable for embedded systems development?

Yes, its bloat-free design and control over memory make it ideal for resource-constrained environments, but you must ensure the required libraries are in usable (green) status and handle platform-specific linking manually.

What is SaneCppLibraries?

Sane C++ Libraries is a collection of platform abstraction libraries for C++ that provide cross-platform APIs for system-level tasks like file I/O, networking, threading, and memory management. It solves the problem of writing portable C++ code without relying on the C++ Standard Library, exceptions, or RTTI, resulting in faster compile times and smaller binaries.

Target Audience

C++ developers building cross-platform applications, system software, or embedded systems who need lightweight, high-performance libraries with minimal dependencies.

Value Proposition

Developers choose Sane C++ Libraries for its strict no-allocations policy, single-file distribution, and avoidance of the C++ Standard Library, which leads to predictable performance, easy integration, and reduced binary bloat compared to traditional C++ libraries.

Overview

Platform Abstraction C++ Libraries

Use Cases

Best For

Building cross-platform C++ applications with minimal dependencies
System programming where control over memory allocation is critical
Embedded or resource-constrained environments requiring small binaries
Projects needing fast compilation times and modular library design
Developing portable tools or utilities for macOS, Windows, and Linux
Writing performance-sensitive code without C++ Standard Library overhead

Not Ideal For

Projects requiring mature, fully-featured HTTP client or server implementations
Teams heavily reliant on C++ Standard Library features, exceptions, or RTTI for error handling and polymorphism
Applications needing extensive integration with third-party libraries or frameworks that assume stdlib usage
Rapid prototyping where high-level abstractions and automatic memory management are preferred over manual control

Pros & Cons

Pros

Platform-Agnostic Abstraction

Provides unified APIs for file I/O, networking, threading, and processes across macOS, Windows, and Linux, as highlighted in the key features, reducing platform-specific code.

Minimal Binary Bloat

Excludes the C++ Standard Library, exceptions, and RTTI, leading to smaller binaries and reduced runtime overhead, which is a core principle stated in the README.

Fast Compilation

Designed for fast compile times with single-file libraries that minimize dependencies and compilation overhead, as emphasized in the principles section.

Predictable Memory Management

Enforces a no-allocations policy using user-provided buffers, ensuring deterministic performance without dynamic memory surprises, detailed in the No Allocations section.

Cons

Immature Feature Set

Key libraries like HTTP are marked as draft (red) in the README, indicating they are incomplete and may lack stability or advanced features needed for production use.

Steep Learning Curve

Requires developers to adapt to manual memory management and error codes instead of exceptions, which can be non-intuitive for those accustomed to standard C++ practices.

Limited Community and Ecosystem

As a niche project, it lacks the extensive documentation, tutorials, and third-party integrations found in established libraries like Boost, making troubleshooting harder.
