WARNING: This project has moved to https://git.yzena.com/ for these reasons.

Yc is a library of utilities for C.

Yc is developed by Yzena.

Yc is Free and Open Source Software (FOSS). It is licensed under a modified Apache License 2.0. The modification was first used by Pixar Animation Studios for use on the OpenSubdiv project.

Getting Started

To get started, clone the repo, and then run the following commands in the root directory:

git config --local include.path ./.gitconfig
git submodule update --init --recursive


Yc depends on CMake. On Ubuntu, it can be installed with the following command:

sudo apt install cmake cmake-curses-gui


Yc is not even in Alpha stage yet. This software is not ready for use.


Yc is written in pure ISO C11.

Git Workflow

Yc uses the git workflow described here. Developers who want to contribute to Yc are encouraged to read that post carefully.

For feature branches, it uses rebase + merge --no-ff (option 3). It also uses a develop/master split. (Main development is on develop, and master just points to the latest tagged release to make it easy for users to get the latest release.)

Commit Messages

Projects under Yzena, including Yc, use the commit message guidelines laid out in this blog post.

Semantic Versioning

Yc uses semantic versioning.

Open Source, Not Open Contribution

Similar to SQLite and Litestream, Yc is open source, not open contribution, for many reasons:

  • The code uses specific implementations of math and bit operations to avoid undefined behavior, so the code "looks" wrong at first glance.
  • New features are required to have a requirements document, a comprehensive specification (preferably in a formal specification language), fully fleshed-out design documents, and a comprehensive test suite.
  • The code uses features specifically in this library to provide the semantics of Rust's borrow checker, but in C. This will also be confusing to newcomers, especially since it uses Structured Concurrency.
  • The code uses an internal build system.
  • The code style is my own slightly eccentric style.
