Workflow

1. Fork and branch

Terminal
git checkout -b feature/your-feature-name

2. Make your changes following the code guidelines below.

3. Commit with clear messages

Terminal
git commit -m "Add mesh arrangements dual function"
git commit -m "Fix intersection curve indexing bug"

4. Push and open a pull request

Terminal
git push origin feature/your-feature-name

Reference the issue (e.g., "Fixes #42") and describe what you did.

Code Guidelines

Trueform is built on composability and zero-copy semantics. When contributing:

  • Build on existing algorithms. Implement new functionality using already-written parallel algorithms. Don't reinvent parallelism—compose it.
  • One function, one file. Each user-facing function in tf:: namespace gets its own file in the module directory.
  • Small functions, delegated responsibilities. Break complex operations into small, focused functions. Each should do one thing clearly.
  • Naming: snake_case for functions/variables, PascalCase for template arguments.
  • Minimize comments. Code should be self-explanatory. Comment only non-obvious algorithmic choices.

Documentation

If you add a public API, update docs/content/ with:

  • What the function does (brief, one sentence)
  • Example usage
  • Return value description if non-obvious

Follow the existing structure in the modules documentation.
