Contributing

tui is an ordinary Rust project where common tasks are managed with cargo-make. It wraps common cargo commands with sane defaults depending on your platform of choice. Bulding the project should be as easy as running cargo make.

Continous Integration

We use Github Actions for the CI where we perform the following checks:

• The code should compile on stable and the Minimum Supported Rust Version (MSRV).
• The tests (docs, lib, tests and examples) should pass.
• The code should conform to the default format enforced by rustfmt.
• The code should not contain common style issues clippy.

You can also check most of those things yourself locally using cargo make ci which will offer you a shorter feedback loop.

Tests

The test coverage of the crate is far from being ideal but we already have a fair amount of tests in place. Beside the usal doc and unit tests, one of the most valuable test you can write for tui is a test again the TestBackend which allows you to assert the content of the output buffer that would have been flushed to the termminal after a given draw call (see widgets_block_renders in tests/widgets_block.rs for an example).
