Hi,
today I started to look into generating something closer to WikiDom from the parser in the ParserPlayground extension. For further testing and parser development, changes to the structure will need to be mirrored in the current serializers and renderers, which likely won't be used very long once the editor integration gets underway.
The serializers developed in wikidom/lib/es seem to be just what would be needed, so I am wondering if it would make sense to put some effort into plugging those into the parser at this early stage while converting the parser output to WikiDom. The existing round-trip and parser testing infrastructure can then already be run against these serializers.
The split codebases make this a bit harder than necessary, so maybe this would also be a good time to draw up a rough plan on how the integration should look like. Swapping the serializers will soon break the existing ParserPlayground extension, so a move to another extension or the wikidom repository might make sense.
Looking forward to your thoughts,
Gabriel
