Convenience? I have a "spoiler" role for rST, for example, which works like this: # state class to contain the counter class _spoiler: count = defaultdict(lambda: 0) def id(src): _spoiler.count[src] += 1 src_hash = sha256(src.encode()).hexdigest()[:7] return f'spoil-{src_hash}{_spoiler.count[src]:03}' def spoiler_role(name, rawtext, text, lineno, inliner, options={}, content=[]): src = inliner.document.attributes['source'] html = ( '<input id="{id}" type="checkbox" class="spoiler" checked />'+\ '<label for="{id}" class="spoiler">{text}</label>' ).format(text=text, id=_spoiler.id(src)) return [nodes.raw('', html, format='html')], [] I don't want to do that manually, and this lets me write :spoiler:`Rosebud was the name of his sled`.
