are now merged with specific registrations by rank. Not yet clear if that is a
good idea overall, need to check use cases when implementing template expansion
and other functionality.
183 parser test now passing.
The TokenTransformDispatcher now actually implements an asynchronous, phased
token transformation framework as described in
https://www.mediawiki.org/wiki/Future/Parser_development/Token_stream_transformations.
Additionally, the parser pipeline is now mostly held together using events.
The tokenizer still emits a lame single events with all tokens, as block-level
emission failed with scoping issues specific to the PEGJS parser generator.
All stages clean up when receiving the end tokens, so that the full pipeline
can be used for repeated parsing.
The QuoteTransformer is not yet 100% fixed to work with the new interface, and
the Cite extension is disabled for now pending adaptation. Bold-italic related
tests are failing currently.
start / row / table end). The old productions are not deleted yet to make it
easy to compare the output on more complex articles. 181 tests passing after
adding two table tests with whitespace-only differences to the whitelist.
This required a few further additions to the TokenTransformDispatcher. In
particular, there is now an 'any' token match whose callbacks are executed
before more specific callbacks. This is used by the Cite extension to eat all
tokens between ref and /ref tags. This need is very common, so should be
broken out to an intermediate layer in the future.
In general, the requirements for the TokenTransformDispatcher API are now
clearer, and the API should likely be cleaned up / simplified.
