File-Level Changes

Change	Details	Files
Introduces a fluent API for waiting on pane content, inspired by Playwright, allowing method chaining for better readability.	Adds the `PaneContentWaiter` class to encapsulate waiting logic. Adds the `expect` function as a convenient entry point for the fluent API. Implements methods like `with_timeout`, `with_interval`, `without_raising`, and `with_line_range` for configuring the waiter. Implements `wait_for_text`, `wait_for_exact_text`, `wait_for_regex`, `wait_for_predicate`, and `wait_until_ready` methods for performing the actual waiting.	`src/libtmux/_internal/waiter.py` `tests/_internal/test_waiter.py`
Adds support for waiting for multiple content patterns, including the ability to wait for any or all of the specified patterns.	Introduces the `wait_for_any_content` function to wait for any of multiple patterns. Introduces the `wait_for_all_content` function to wait for all of multiple patterns. Updates the `WaitResult` dataclass to include a `matched_pattern_index` attribute for `wait_for_any_content`. Adds comprehensive tests for both `wait_for_any_content` and `wait_for_all_content`.	`src/libtmux/_internal/waiter.py` `tests/_internal/test_waiter.py`
Enables the use of mixed pattern types, allowing different match types (exact, contains, regex, predicate) in a single call.	Modifies `wait_for_any_content` and `wait_for_all_content` to accept a list of `ContentMatchType` values. Adds type checking to ensure that the pattern type is compatible with the match type. Adds tests to verify that mixed pattern types work correctly.	`src/libtmux/_internal/waiter.py` `tests/_internal/test_waiter.py`
Improves error handling with detailed type checking.	Adds specific error messages for invalid pattern types in `wait_for_pane_content`, `wait_for_any_content`, and `wait_for_all_content`. Adds type checking to ensure that the pattern type is compatible with the match type. Adds tests to verify that type errors are raised correctly.	`src/libtmux/_internal/waiter.py` `tests/_internal/test_waiter.py`
Adds elapsed time tracking for timing information.	Adds `elapsed_time` to the `WaitResult` dataclass. Updates `wait_for_pane_content`, `wait_for_any_content`, and `wait_for_all_content` to calculate and store the elapsed time. Adds tests to verify that the elapsed time is calculated correctly.	`src/libtmux/_internal/waiter.py` `tests/_internal/test_waiter.py`
Improves type annotations for better IDE support and static type checking.	Adds type hints to all functions and methods in the `waiter` module. Uses `t.TYPE_CHECKING` to avoid circular imports. Adds mypy overrides for test examples.	`src/libtmux/_internal/waiter.py` `tests/_internal/test_waiter.py` `pyproject.toml`
Creates comprehensive documentation.	Creates a new documentation page for the waiter module. Adds examples for all usage patterns, including the new fluent API. Updates the API reference with accurate return types. Adds a detailed explanation of the `WaitResult` object properties. Updates example code in `test_wait_until_ready.py` to use `contextlib.suppress`. Makes all examples compatible with automated testing and documentation. Ensures documentation is now fully synchronized with code examples via `literalinclude` directives.	`docs/internals/waiter.md` `docs/internals/index.md` `tests/examples/_internal/waiter/test_wait_until_ready.py`
Adds an example file demonstrating different ways to use the enhanced API.	Creates a new example file in `tests/examples/test/test_waiter.py`. Ensures examples follow best practices and appropriate error handling. Adds examples showing how to properly handle timeouts.	`tests/examples/test/test_waiter.py`
Fixes linting and formatting issues throughout the waiter module.	Runs `ruff format` on the `waiter` module. Addresses any linting errors reported by `ruff check`.	`src/libtmux/_internal/waiter.py`
Makes the shell prompt detection more robust using common prompt characters.	Updates the `wait_until_pane_ready` function to use a more robust shell prompt detection mechanism. Uses common prompt characters such as `$`, `%`, `>`, and `#` to identify the shell prompt.	`src/libtmux/_internal/waiter.py` `tests/_internal/test_waiter.py`

Hey @tony - I've reviewed your changes - here's some feedback:

Overall Comments:

Consider adding a helper function to reduce duplication in tests that involve sending commands to a pane and waiting for a result.
The new fluent API looks great, but ensure that the documentation clearly explains when to use the fluent API vs. the existing functions.

Here's what I looked at during the review

🟢 General issues: all looks good
🟢 Security: all looks good
🟡 Testing: 3 issues found
🟢 Complexity: all looks good
🟢 Documentation: all looks good

Hey @tony - I've reviewed your changes - here's some feedback:

Overall Comments:

Consider adding a helper function to encapsulate the logic for creating a new window and pane, as this pattern is repeated throughout the tests.
The addition of the waiter module and its tests is a significant enhancement, but it also adds complexity. Ensure that the documentation is comprehensive and easy to understand for new contributors.

Hey @tony - I've reviewed your changes - here's some feedback:

Overall Comments:

Consider adding a helper function to encapsulate the logic for creating and cleaning up test windows and panes to reduce code duplication across tests.
The new waiter module introduces a lot of new code - consider adding a diagram or high-level overview to the documentation to help users understand the different components and how they fit together.

…iters - Create detailed markdown documentation in docs/test-helpers/waiter.md - Add key features section highlighting main capabilities - Include quick start examples for all functions - Document fluent API with Playwright-inspired design - Explain wait_for_any_content and wait_for_all_content with practical examples - Add detailed API reference for all waiters - Include testing best practices section

- Adds a conftest.py file in tests/examples to register the pytest.mark.example marker - Eliminates pytest warnings about unknown markers in example tests - Improves test output by removing noise from warnings

- Each test file focuses on a single feature or concept of the waiter module - Added descriptive docstrings to all test functions for better documentation - Created conftest.py with session fixture for waiter examples - Added helpers.py with utility functions for the test examples - Test files now follow a consistent naming convention for easier reference - Each test file is self-contained and demonstrates a single concept - All tests are marked with @pytest.mark.example for filtering This restructuring supports the documentation update to use literalinclude directives, making the documentation more maintainable and ensuring it stays in sync with actual code.

Hey @tony - I've reviewed your changes - here's some feedback:

Overall Comments:

Consider adding a helper function to encapsulate the logic for killing windows safely, to avoid repetition in test cleanup.
The addition of comprehensive tests and examples is great, but ensure that these are also regularly reviewed and updated to reflect any API changes.
