Implementation Summary
Complete TDD8 workflow implementation of instant markdown base and publication directory functionality. Extended md-render command to support both single files and directory processing with publication directory management, environment variable override, and CLI flags for behavior control. Generated comprehensive test suite with 18 tests covering all scenarios from publication directory management to edge cases.
Key Features Delivered
- Publication directory support with ~/Notes/ default and MARKITECT_PUBLICATION_DIR override
- Single file processing with --use-publication-dir flag
- Directory processing with recursive traversal and structure preservation
- --dont-use-publication-dir flag for placing HTML next to MD files
- Comprehensive CLI integration with detailed help documentation
- 9 new helper functions for directory/file processing
- Full backward compatibility maintained
- Extensive test coverage (18 tests, 100% pass rate)
Technical Implementation Details
- Modified md-render command with new CLI options and directory support
- Added publication directory management functions (get_publication_directory, normalize_publication_path, ensure_publication_directory)
- Implemented file processing functions (process_single_file, process_directory, find_markdown_files)
- Created utility functions (get_output_filename, get_relative_output_path, _render_single_markdown_file)
- Updated command help documentation with examples and usage patterns
- Comprehensive error handling and edge case management
Test Coverage Breakdown
- Publication Directory Management (4 tests): Default directory, environment variable override, directory creation, path normalization
- Single File Processing (3 tests): Default behavior, publication directory usage, naming conventions
- Directory Processing (4 tests): Publication directory with structure, HTML next to MD, recursive traversal, structure preservation
- CLI Integration (4 tests): Flag presence, directory input support, environment variable integration
- Edge Cases (3 tests): Empty directories, mixed content, error handling
