It takes a human-readable expression like `@fast and not @slow` or `(@login or @registration) and @critical`, parses it into an evaluable form, and then checks whether a given set of tags satisfies that expression. The package has no runtime dependencies and is designed to integrate with test runners like behave, which use tag expressions to filter which scenarios to execute.\n\nThe typical workflow is: a test runner receives a tag expression from the command line (e.g., `--tags=\"@smoke and not @wip\"`), passes it to this package's `parse()` function, and then evaluates the resulting object against the tags on each scenario. It supports the full boolean algebra of `and`, `or`, and `not` operators, with parentheses for grouping, making it possible to express complex filtering logic in a readable, declarative way.","worth_installing":"Yes. This is a lightweight, actively maintained library with zero dependencies, permissive licensing, and a clear, focused purpose. Install it if you are building or using a Gherkin-based BDD test runner (such as behave) or need to parse and evaluate tag expressions for test selection.
