Extracted suffix_separator, suffix_start, and suffix_end from cfg at the start of the function to avoid repeated dictionary lookups and improve code readability.
Refactor the sphinx_gated_directives extension to support configurable suffixes and separator for start/end directives, and add an 'override_existing' option for more flexible directive registration. Update the registry naming and logic throughout the extension, add configuration validation, and update the book config and intro to demonstrate new exercise directives and nesting.
Improved code structure and comments in sphinx_gated_directives/__init__.py, clarified logic, and removed unused/legacy code. Updated intro.md to remove commented-out directive examples and replaced them with active ones for better demonstration and testing.
Added a robust validate_SE function to check for correct nesting of start and end directives, with detailed error reporting. Updated the CheckGatedDirectivesTransform to use this validation and improved error messages for mismatched or incorrectly nested directives. Extended intro.md with comprehensive examples of nested directives, including both valid and invalid cases, to document and test the new behavior. Also added the sphinx_tudelft_theme extension in _config.yml.
Debug logging statements were removed from MergeGatedDirectivesTransform in sphinx_gated_directives. The intro.md file was updated to include new theorem and figure directive examples, code cells, and additional documentation content.
Commented out the code related to the 'sphinx_gated_directives_registry' in favor of using only the 'sphinx_gated_directives_super_registry'. Updated purge and transform logic accordingly. Added clarifying comments to code-align.css regarding left alignment enforcement.
Introduces the custom Sphinx extension 'sphinx_gated_directives' for start/end directive gating and validation, registering it in the Sphinx local extensions. Also adds a CSS file to enforce left alignment for code cells. Updates _config.yml to configure the new extension and set the documentation language to English.
Removed local APA style extensions and related static files, updated _config.yml to use the sphinx_apa_references extension, and revised documentation in apa.md to reflect installation and usage of the new package. Added sphinx-apa-references to requirements.txt and references.bib now includes a multi-author example for APA citation demonstration.
