My public repositories

Here is a list of my public repositories, with a brief description.

Highlights

micro-headers

A collection of high-quality, configurable, header-only libraries written in C99. The libraries are designed to be highly reusable, simple to maintain with little to no dependencies, and easy to integrate in your projects. website

  • micro-tests.h: lightweight testing framework, with multithread support and run-time settings
  • micro-log.h: configurable, thread safe logging framework in C99. With lots of features
  • micro-draw.h: a 2D software renderer
  • micro-lex.h: simple lexer for lisp-like languages, and others. See also justlex-rs crates.io
  • micro-arena.h: memory allocator (first fit). It implements the common memory functions from stdlib.h.

  • rendezvous-hasher.h: dependency-free implementation of Rendezvous Hashing (a.k.a. Highest Random Weight hashing), useful for distributing keys across a dynamic set of nodes
  • consistent-hasher.h: implementation of consistent hashing, alternative to rendezvous-hashing
  • hashmap.h: implementation of an hashmap for any type
  • hashset.h: implementation of an hashset for any type

Setup

Custom configurations for my daily development setup and workflow.

My Favourite libraries

These are the libraries that I use the most in my projects and that I find incredibly useful.

  • RGFW (C99): when you just want to open a window in a cross-platform way, love it!
  • stb headers (C): great source of inspiration and knowledge. There are some other headers in the creator's website such as stb_malloc.c.
  • raylib (C99): simple 2D/3D graphics library
  • micro-headers (C99): my own cool libraries for all my other projects
  • csynth (C): A simple synth in C, very fun to explore the code, It is somewhat unusual and enlightening.
  • luigi (C): single header GUI framework in C. It is absurdly simple and well written, amazing read.
  • nginx (C): even if it is not a library, each source file is well divided from the others so that you can copy paste almost everything in your projects!
  • SDL (C): my goto library for writing desktop applications
  • miniaudio (C): my goto library to play and mix audio
  • SFML (c++17): another great multimedia library, more ideomatic for C++
  • moviepy (Python): edit videos from python
  • wren (C): the most elegantly implemented programming language I have ever seen

Minor Contributions

Minor contributions all over the interweb:

There are many more which are not really interesting or are not public, so I didn't mention them.
