## [Unreleased]
### Added
### Fixed
### Changed
### Removed
# 5.2.0 [2025-10-25]
### Added
- `applySkips` function for skipping entire test trees with individual test visibility
- Traverses test trees and replaces tests with skipped placeholders
- Shows each test as `[SKIPPED]` in yellow when skip condition is met
- Useful for platform-specific test suites with `Flavored (IO TestTree)`
- Preserves test group structure while showing which tests would run
- Comprehensive platform expression tests covering all operators and edge cases
- Added tests for `!darwin`, `!mingw32`, `!unix` negations
- Added tests for complex AND/OR expressions
- Added tests for edge cases like unknown platforms (freebsd)
### Changed
- Migrated release process to tag-triggered workflow
- Release workflow now triggers when version tags (e.g., v5.2.0) are pushed
- Removed automatic tag creation from CI
- Updated release documentation to reflect tag-based process
- `--inplace` option now only overwrites file if content has changed
- Prevents unnecessary file modification timestamps
- Reduces build system churn when generated file is identical
# 5.1.0 [2025-08-10]
### Added
- Assertion newtype wrapper for HUnit-style assertions with comprehensive documentation and examples (see #74)
- Platform-specific test examples and documentation showing skip/platform usage (see #69)
- Support for GHC 9.12.2 in tested configurations (see #53)
- Reproduction test for symlink crash issue (see #38)
- New `--no-main` option for generating modules without main function (see #54)
- Support for custom tests with `Tasty` instances using `tasty_` prefix
- New `TastyInfo` type providing access to test metadata in custom tests
- **`Flavored` type**: General-purpose mechanism for transforming `TestTree`s generated by `tasty_` functions
- Allows applying transformations like skipping, timeouts, metadata, grouping, etc.
- Extensible design with `flavoring :: TestTree -> TestTree` transformation function
- Integrates seamlessly with custom test types through `Tasty` instances
- **Skip test functionality**: Added `SkipTest` option type and `skip` function
- `SkipTest` newtype with `IsOption` instance for Tasty options
- `skip :: TestTree -> TestTree` function to skip any test tree
- Skipped tests show as `[SKIPPED]` in yellow in test output
- Works with `Flavored` type for advanced skip patterns
- Comprehensive documentation for all test type variations
- Step-by-step testing support for HUnit tests
- IO-based test generation for TestTrees
- AI development guidelines in AI_GUIDELINES.md
- Comprehensive coding style guide in CODING_STYLE.md
- Multiline block comment handling in test discovery (resolves #10)
### Fixed
- Fixed backup file import generation bug - prevents `.hs.orig` and `.hs.bak` files from being processed (see #58)
- Fixed directory handling in glob patterns - directories are now filtered out when using `--modules` flag (resolves #12)
- Fixed HLint warnings in generated code
- Fixed warnings in Generator.hs and added Unsafe.hs module
- Fixed broken links in documentation
- Fixed test discovery incorrectly finding tests inside `{- -}` block comments (resolves #10)
### Changed
- Enhanced documentation for skip and platform guidance (see #72)
- Cleaned up cabal file configuration
- Improved test discovery patterns from `*.hs*` to `*.hs` to avoid backup files
- Enhanced documentation with more test type examples
- Added regression tests for backup file handling and directory filtering
- Added preprocessing step to remove block comments before test discovery
- Enhanced test discovery with proper nested block comment support
