Universal Variability Language (UVL)

Welcome to the Universal Variability Language (UVL) organization on GitHub!

About UVL

UVL is a concise, extensible language for modeling variability in software product lines. This organization houses multiple related projects that support the definition, parsing, tooling, and ecosystem around UVL. See our public site: https://universal-variability-language.github.io/

Key Repositories

Here are some of the main projects under this organization:

Repository Purpose
uvl-parser The grammar / parser definition of UVL, based on ANTLR
java-fm-metamodel Java library to manipulate UVL metamodels; uses the UVL grammar
uvl-models A repository containing a catalog of publicly available feature models expressed in UVL
uvl-lsp A Language Server Protocol (LSP) implementation for UVL
uvl-tutorials-material Teaching / tutorial resources for UVL usage
UVLEP The UVL Enhancement Process (for evolving the language)

Organization Governance & Contribution

We aim to maintain transparency, collaboration, and quality across all projects in this organization. Below are some guidelines:

Contribution Welcome 🎯

  • Issue tracker: Use issues in the respective repository to propose enhancements, report bugs, or request features.
  • Pull requests: Fork the repo, create a feature branch, commit changes, and open a PR. Please follow the repository’s coding / style / testing conventions.
  • Review process: At least one reviewer will approve changes; maintainers may suggest adjustments.
  • Code of Conduct / License: Each repository should include a license and a code of conduct. If not present, raise an issue to have one added.

UVL Enhancement (Language Evolution)

Changes to the UVL language itself should follow a formal proposal process via the UVLEP repository. Language-level changes must be backwards-compatible where possible, or include migration guidance if incompatible.
