UTL

UTL is a collection of small self-contained libraries with a major aim towards usage simplicity. It was mostly created during my work in gamedev and mathematical research for the purpose of fast prototyping.

For the ease of integration, all libraries are distributed as individual headers, which can be found here.

The entire collection can also be downloaded as an amalgamated single-header.

CMake FetchContent() support is also provided.

Design goals

Implementation of this library sets following design goals:

• Easy integration. Adding libraries to the project should be as simple as including their corresponding headers.
• Concise syntax. Library usage should require minimal boilerplate on user side.
• Platform agnostic. Implementation should be based around the C++ standard. Platform-specific features might be provided as optional addons.
• Non-intrusive. Every library should reside in its own namespace, use its own macro prefix and not introduce any invasive identifiers.

Quality goals include:

• Modern C++ style. Usage of modern C++ idioms is heavily preferred.
• Usage examples. Documentation should include practical usage examples for all major methods.
• Test & benchmark coverage. All modules should have appropriate unit test coverage, performance-focused implementations should be benchmarked against alternative approaches.
• Easy to build. All headers, tests, benchmarks and examples should build under the strictest warning levels and with minimal tooling.

Requirements

• Requires C++17 support
• Some headers require a compliant preprocessor flag (/Zc:preprocessor) when using MSVC, such headers specify it in the docs

Developer toolchain

While the library itself consists of isolated headers with no embedded dependencies, it was built and tested using a number of third-party tools and libraries, some of which are embedded in the repo.

Roadmap

• Create packages for Conan and vcpkg
• Possibly provide PCH targets for internal and external use
• Set up better test coverage statistics
• utl::mvl v1.0.0 release, involves a large scale refactor and several bug fixes
• utl::random v3.0.0 release, includes CBPRNGs and fixed-entropy seeding sequence
