Maybe something similar to the above could be done also for some non-paragraph data. By looking at: https://docutils.sourceforge.io/docs/ref/doctree.html It says that the body elements are: admonition, attention, block_quote, bullet_list, caution, citation, comment, compound, container, danger, definition_list, doctest_block, enumerated_list, error, field_list, figure, footnote, hint, image, important, line_block, literal_block, note, option_list, paragraph, pending, raw, rubric, substitution_definition, system_message, table, target, tip, warning So, perhaps a similar loop for definition_list would do the trick, but maybe automarkup should also look at other types, like enum lists, notes (and their variants, like error/warning) and footnotes. No idea how this would affect the docs build time, though. > Only applying the automarkup inside paragraphs seems like a good decision (which > covers text in lists and tables as well), so unless there are other types of > elements without paragraphs where automarkup should work, I think we should just > avoid using definition lists pointing to documents like that. Checking the code or doing some tests are needed for us to be sure about what of the above types docutils don't consider a paragraph. Thanks, Mauro
