Cleaned up book/_config.yml by removing unused or unnecessary Sphinx configuration options related to sphinx_gated_directives and sphinx_codex. This helps simplify the configuration file.
The sphinx_tudelft_theme extension has been removed from the list of Sphinx extensions in the configuration file, possibly because it is no longer needed or has been replaced.
Deleted the custom 'include_remove_yaml' Sphinx extension and its configuration. Cleaned up YAML front matter from intro.md. Updated requirements.txt to use released teachbooks package, added sphinx-gated-directives, and removed duplicate or outdated dependencies.
Introduced a custom Sphinx extension 'include_remove_yaml' to strip YAML front matter from included files. Updated _config.yml to register the extension, and added YAML front matter to intro.md for demonstration.
Removed the local sphinx_gated_directives extension and updated configuration to use the external package. Added Sphinx-Gated-Directives as a dependency in requirements.txt and adjusted _config.yml to load it as an extra extension.
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.
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.
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.
Integrated the sphinx-github-alerts extension into the Sphinx configuration, requirements, and documentation table of contents to enable GitHub alerts functionality.
Removed custom bibtex style settings from _config.yml. Added documentation in apa.md about handling duplicate label warnings in APA references, including advice on adding letters to years in .bib files.
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.
Included the sphinx-accessibility extension in the Sphinx configuration and requirements. Updated the table of contents to reference the Sphinx-Accessibility manual for improved documentation coverage.
Integrated the sphinx-code-examples extension by updating _config.yml, _toc.yml, and requirements.txt. This adds support for code example features and links to its manual in the table of contents.
