UTL is a collection of small self-contained libraries aimed at prototyping with minimal boilerplate. Most of the modules were created during my work in gamedev and math research projects.
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.
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.

While the library itself consists of a single header 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.
