Gabriel Wicke a5cc10a06b Change token format to plain strings for text tokens, and specific objects for
other tokens. This is only the first half of the conversion. The next step is
to drop the type attribute on most tokens and match on the constructor in the
token transform machinery.

Gabriel Wicke 7cd94df47d A few minor tweaks to reduce memory usage 2012-01-27 13:32:44 +00:00
Gabriel Wicke 4e6a54560a * Emit token chunks for top-level block elements by patching the source of the
tokenizer
* Fix a bug uncovered by this
* Increase the number of outstanding listeners on a single download to 10000

Gabriel Wicke 34025251a3 Clean up 'END' token handling a bit. 2012-01-17 20:01:21 +00:00
Gabriel Wicke 287604c422 A bit of cleanup in ParserPipeline, with better and more consistent support
for multiple input types.

Gabriel Wicke e99d7a2a55 Two batteries worth of token transform manager refactoring.
* TokenTransformDispatcher is now renamed to TokenTransformManager, and is
  also turned into a base class
* SyncTokenTransformManager and AsyncTokenTransformManager subclass
  TokenTransformManager and implement synchronous (phase 1,3) and asynchronous
  (phase 2) transformation stages.
* Communication between stages uses the same chunk / end events as all the
  other token stages.
* The AsyncTokenTransformManager now supports the creation of nested
  AsyncTokenTransformManagers for template expansion.
  The AsyncTokenTransformManager object takes on the responsibilities of a
  preprocessor frame. Transforms are newly created (or potentially resurrected
  from a cache), so that transforms do not have to worry about concurrency.
* The environment is pushed through to all transform managers and the
  individual transforms.

Gabriel Wicke 6601c544e6 Handle default for template arg expansion, add template fetch functionality
and tweak a few minor things in the grammar and QuoteTransformer.

Gabriel Wicke 6cd95fea37 Fix up constructors in EventEmitter inheritance and tweak a few more comments. 2012-01-04 12:28:41 +00:00
Gabriel Wicke 29362cc53c Rename ParseThingy to ParserPipeline and fix up broken WikiDom generation and
commandline runner.

Gabriel Wicke bd98eb4c5a Land big TokenTransformDispatcher and eventization refactoring.
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.

Neil Kandalgaonkar 20374b5911 fix substr for IE, followup r107464 2011-12-30 21:51:03 +00:00
Gabriel Wicke b3a0270d69 Remove env and load grammar in tokenizer constructor. Re-add property hack to
keep parserTests running for now. Really need a different pipeline for html
serialization or a reference to the HTML DOM.

Neil Kandalgaonkar 8fbf36e63e put add terminal token inside tokenize method (will pull it out again for streaming interface) 2011-12-28 01:37:15 +00:00
Neil Kandalgaonkar 6103646ec8 remove need to add newline at end of input 2011-12-28 01:37:11 +00:00
Neil Kandalgaonkar 962d1262fc create tokenizer without need to modify namespace with PEG source 2011-12-28 01:36:36 +00:00
Gabriel Wicke 752b0990b2 Refactor parserTests somewhat into a class-like structure, and wire up the
TokenTransformer.
2011-12-12 14:03:54 +00:00
Gabriel Wicke d616f07a79 Don't re-build the wiki tokenizer for each test. This speeds up the full
parserTests.js run slightly from 7-8 minutes to about 14 seconds ;)

A few very minor tweaks to the grammar are also thrown into this commit.
2011-12-12 10:47:42 +00:00
Gabriel Wicke abc2254110 A bit of comment clean-up and wrapping of tree building into try/catch block
to actually count failures.
2011-12-08 11:40:59 +00:00
Gabriel Wicke 92fdf99384 Further renaming, this time from pegParser to pegTokenizer. 2011-12-08 10:59:44 +00:00
Renamed from modules/parser/mediawiki.parser.peg.js (Browse further)
