Wikitext to HTML serializer.
This serializer is designed to eventually
- accept arbitrary HTML and
- serialize that to wikitext in a way that round-trips back to the same HTML DOM as far as possible within the limitations of wikitext.
Not much effort has been invested so far on supporting non-Parsoid/VE-generated HTML. Some of this involves adaptively switching between wikitext and HTML representations based on the values of attributes and DOM context. A few special cases are already handled adaptively (multi-paragraph list item contents are serialized as HTML tags for example, generic A elements are serialized to HTML A tags), but in general support for this is mostly missing.
Example issue:
<h1><p>foo</p></h1> will serialize to =\nfoo\n= whereas the
correct serialized output would be: =<p>foo</p>=
What to do about this?
- add a generic 'can this HTML node be serialized to wikitext in this context' detection method and use that to adaptively switch between wikitext and HTML serialization.
