Top 23 C++ C Projects

  • GitHub repo FlatBuffers

    FlatBuffers: Memory Efficient Serialization Library

    Project mention: FlatBuffers vs Protocol Buffer | reddit.com/r/cpp | 2021-01-25

    However, protobuf generally has better support. (Recent grpc versions seem to have broken FB support, unfortunately)

  • GitHub repo Sourcetrail

    Sourcetrail - free and open-source interactive source explorer

    Project mention: The Database Inside Your Codebase | news.ycombinator.com | 2021-02-16

    I'm with you on this one. I'd actually suggest https://github.com/CoatiSoftware/Sourcetrail could be extended to do this, though I haven't found the time yet. For example https://github.com/CoatiSoftware/SourcetrailPythonIndexer and under the hood the file format is SQLite: https://github.com/CoatiSoftware/SourcetrailDB

  • Scout

    Get performance insights in less than 4 minutes. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.

  • GitHub repo OpenRCT2

    An open source re-implementation of RollerCoaster Tycoon 2 🎢

    Project mention: Last months in OpenRCT2 #5 (February 2021) | reddit.com/r/rct | 2021-02-23

    My pick is this one: https://github.com/OpenRCT2/OpenRCT2/pull/12888

  • GitHub repo Apache Thrift

    Apache Thrift

    Project mention: Can you share your experience with race conditions in production? | reddit.com/r/java | 2021-01-25

    We were sharing instances of a Thrift TDeserializer across threads. We knew TProtocol was not thread-safe, but the TDeserializer constructor accepts a TProtocolFactory, so we naively assumed the deserialize method would use that to create a new instance of TProtocol for each invocation, but unfortunately, the TDeserializer constructor immediately creates TProtocol and stores it in a member variable, so TDeserializer is not actually thread-safe.

  • GitHub repo GuiLite

    ✔️The smallest header-only GUI library(4 KLOC) for all platforms

    Project mention: Deeply understand your GitHub/GitLab project | reddit.com/r/github | 2021-01-17

    You can get source code here

  • GitHub repo fswatch

    A cross-platform file change monitor with multiple backends: Apple OS X File System Events, *BSD kqueue, Solaris/Illumos File Events Notification, Linux inotify, Microsoft Windows and a stat()-based backend.

    Project mention: Can I version control directories like /Applications, /Library/Application Support, /usr/local etc using Git? | reddit.com/r/MacOS | 2021-02-13

    Found an interesting tool while searching for a readily available solution: https://github.com/emcrisostomo/fswatch but not sure if it is kind of always on or not. Requires port or brew to install it, so not able to test it.

  • GitHub repo nghttp2

    nghttp2 - HTTP/2 C Library and tools

  • GitHub repo Cppcheck

    static analysis of C/C++ code

  • GitHub repo ArrayFire

    ArrayFire: a general purpose GPU library.

  • GitHub repo harfbuzz

    HarfBuzz text shaping engine

    Project mention: Bug: Kerning broken. - Dev: You can try to get used to the "blurry" rendering. Or you can find something else to use, or whatever. You are using Free Software you realize, right? | reddit.com/r/programmingcirclejerk | 2021-01-12

    Quality off-topic jerk down below

  • GitHub repo Teeworlds

    A retro multiplayer shooter

  • GitHub repo OpenJK

    Community effort to maintain and improve Jedi Academy (SP & MP) + Jedi Outcast (SP only) released by Raven Software

    Project mention: Compiling OpenJK | reddit.com/r/linux_gaming | 2021-01-23

    I am hoping he is referring to this :) https://github.com/JACoders/OpenJK Which is an open source version of the starwars jedi knight academy games.

  • GitHub repo faust

    Functional programming language for signal processing and sound synthesis (by grame-cncm)

    Project mention: Audio DSP language SOUL reaches V1.0 status | reddit.com/r/programming | 2021-01-21

    Had a look at some Faust publications; you're right, very similar concepts; and as it seems it's still actively developed: https://github.com/grame-cncm/faust; and it even supports FPGAs; amazing.

  • GitHub repo ccache

    ccache – a fast compiler cache

    Project mention: building new kernels frequently | reddit.com/r/archlinux | 2021-02-13

    ccache is a tool for the gcc compiler used to compile the same program over and over again with little downtime. While it may take a few seconds longer to compile a program the first time with ccache, subsequent compiles will be much, much faster.

  • GitHub repo enkiTS

    A permissively licensed C and C++ Task Scheduler for creating parallel programs. Requires C++11 support.

    Project mention: Voxel Vendredi 74 | reddit.com/r/VoxelGameDev | 2021-01-08

    GL_MAP_PERSISTENT_BIT for any data which is changed per-frame, such as constant buffers, particle data, SSBO data etc. This allows the data to be written in parallel (I use my tasking system enkiTS).

  • GitHub repo cr

    cr.h: A Simple C Hot Reload Header-only Library (by fungos)

    Project mention: What are good Lua alternatives as an embeddable language? | reddit.com/r/gamedev | 2021-01-17

    Depends on your use case, but I would second the option of just hot reloading c++. I have been experimenting with that (using cr.h) and its great - as long as you make sure your compile and link times are fast enough.

  • GitHub repo ImGuiColorTextEdit

    Colorizing text editor for ImGui

    Project mention: Show HN: Virtual breadboard in your desktop browser, inspired by Ben Eater 6502 | news.ycombinator.com | 2021-01-19

    The text editor is this one https://github.com/BalazsJako/ImGuiColorTextEdit, it's listed on the third-party attributions page (https://www.tejotron.com/thirdparty.html)

  • GitHub repo slop

    slop (Select Operation) is an application that queries for a selection from the user and prints the region to stdout. (by naelstrof)

    Project mention: Some nifty stuff ffmpeg can do | reddit.com/r/linux | 2021-02-13

    Here: https://github.com/naelstrof/slop

  • GitHub repo mull

    Practical mutation testing tool for C and C++

    Project mention: Mutation Driven Testing: When TDD Just Isn’t Good Enough | news.ycombinator.com | 2021-02-06

    re: absence of C++ tools

    Have you looked at Mull[1] or Dextool[2]?

  • GitHub repo dsd

    Digital Speech Decoder (by szechyjs)

    Project mention: Anyone in GTA/Toronto, Canada have any interesting frequencies to listen to? | reddit.com/r/RTLSDR | 2020-12-24

    Try scanning around for some digital stuff with https://github.com/szechyjs/dsd

  • GitHub repo Enzyme

    High-performance automatic differentiation of LLVM. (by wsmoses)

    Project mention: news.ycombinator.com | 2021-02-17

    Hi all, another author here and happy to answer any questions!

    Some more relevant links for the curious

    Github: https://github.com/wsmoses/Enzyme

    Paper: https://proceedings.neurips.cc/paper/2020/file/9332c513ef44b...

    Basically the long story short is that Enzyme has a couple of interesting contributions:

    1) Low-level Automatic Differentiation (AD) IS possible and can be high performance

    2) By working at LLVM we get cross-language and cross-platform AD

    3) Working at the LLVM level actually can give more speedups (since it's able to be performed after optimization)

    4) We made a plugin for PyTorch/TF that uses Enzyme to import foreign code into those frameworks with ease!

  • GitHub repo fff

    A testing micro framework for creating function test doubles
