lightmapper.h is a C/C++ single-file library for lightmap baking by using your existing OpenGL renderer.

Epoxy is a library for handling OpenGL function pointer management for you

Linenoise is a lightweight C library for terminal line editing, command history management, and asynchronous input processing. It functions as a self-contained alternative for capturing user input from the command line without requiring external dependencies. The utility provides a non-blocking input processor that handles keyboard data via a feed mechanism, allowing applications to process user typing and external events simultaneously. It supports the implementation of custom shells and REPLs through features such as callback-based autocompletion, input hinting, and a circular history buffe

sds is a C dynamic string library that provides a memory management wrapper for heap-allocated strings. It implements binary-safe storage by tracking string lengths explicitly, allowing the library to handle null characters within data. The library distinguishes itself through a memory architecture that uses interchangeable function pointers for allocation and freeing, enabling the integration of custom memory managers. It utilizes header-stored length tracking to provide constant-time length retrieval and maintains null-terminated buffer padding to ensure compatibility with standard C string

Small strings compression library

Small & portable byte-aligned LZ77 compression

EasyLogger is a lightweight C/C++ logging library and asynchronous framework designed for embedded systems, IoT devices, and wearables. It functions as a resource-efficient logger and flash memory manager, providing tools for low-level debugging and system event recording with minimal ROM and RAM requirements. The project distinguishes itself through an asynchronous logging model that buffers messages to a separate thread, preventing logging operations from blocking real-time application execution. It includes a specialized flash memory manager that utilizes circular buffering to persist logs

s2n is a C-based security library and TLS protocol implementation that serves as a secure network transport layer. It provides a modular cryptographic backend interface to encrypt data streams, manage handshakes, and handle mutual authentication between peers. The project focuses on post-quantum cryptography, integrating quantum-resistant key exchange and digital signatures to protect connections against future computing threats. It distinguishes itself through security hardening measures, such as memory-locked secret storage to prevent keys from being swapped to disk and timing-attack mitiga
