Implements Bun as a new language option for pre-commit hooks, enabling hooks to run using the Bun JavaScript runtime and package manager. - Add bun.py language implementation with binary download/install - Support system-installed Bun or automatic version download - Add comprehensive tests including version handling and hook execution - Register bun in all_languages.py - Include test repository fixture for integration tests
Adds the oven-sh/setup-bun@v2 action to install Bun when running language tests for the Bun language support added previously.
Add comprehensive unit tests to cover all code paths in the Bun language implementation: - Platform detection tests for darwin, linux, windows, and unsupported platforms - Version normalization tests for all format variations (default, plain numbers, v-prefix, bun-v-prefix) - HTTP error handling tests for 404 and other error codes - Binary extraction edge case tests for missing directories and missing executables - System version installation path test to verify binary download is skipped when using system bun Coverage increased from 87% to 100% with no lines or branches missing. All tests use mocks to avoid requiring network calls or platform-specific behavior, ensuring fast and reliable test execution.
