Pages titles with a wikipedia interwiki prefix now load the page from
corresponding Wikipedia. Links in a page then stay within the given language.
Note that Parsoid currently makes no effort to recognize localized namespaces,
so it won't render media files, categories etc correctly.

* Don't explicitly add the newline in the pre, as we preserve newline tokens
now. This avoids doubling of newlines when round-tripping.
* Use the sHref attribute even if the href contains spaces.
Change-Id: I8bec8fbfd6a7836bf2e5eec20869a0edd95c93b6
Lists interrupted by non-empty lines would not close the list properly.
Register for any token instead of just for newlines and close the list if no
listItem follows the newline.

If the href would not denormalize, add a copy of the original href in data-mw
and use it to preserve non-conventional capitalization etc.

A tail containing regexp syntax (a ? in [[:en:Main Page]]) would crash the
serializer. Use substr instead.

- Added a tail json attribute for wikiLinks
- During serialization, this attribute is used to strip the tail from
the link target and render it after the link
[[hen]]s ==> <a ... data-mw="{gc:1, tail: 's'}" ...>hens</a>
==> [[hen]]s
- 2 more roundtrip tests green

* The state of syntax stops is now properly included in the cache key for the
tokenizer-internal backtracking cache. This fixes some mis-parses when
re-parsing a bit of text with different flags.
* Clear the backtracking cache after each toplevelblock. This drops the peak
memory usage when expanding [[:en:Barack Obama]] from ~380M to ~110M.

* This routine attempts to rewrite the DOM to maximize tag overlap
and thus minimize tag uses.
* This takes as input a set of tags which participate in the
minimization.
* Tested on the following example
<b><i><u><s>BIUS</s></u></i></b><b><i><s>BIS</s></i></b><b><u><s>BUS</s></u></b><u><i>UI</i></u>
with multiple combinations of the 2^4 possible variations of i,b,u,s
tags: [], ['i','b','u','s'], ['i'], ['b','s'], ['i','b','u']
- But, I am not fully sure if this implements the right behavior when
only a subset of inline tags are provided. Needs discussion and tweaking
as necessary.
* Also tested on few others:
<b>B</b><b><i>BI</i></b><b><i><u>BIU</u></i></b><b><i><u><s>BIUS</s></u></i></b>
<s><i><b>SIB</s></i></b><s><i><u>SIU</u></i></s><i><u>IU</u></i><i>I</i>
* The previous pairwise tag rewriting version fails on several of these
examples, so this new version is a definite improvement.
* No change in parserTests run (203 passing before and after).
* Possible improvements that could/should be undertaken:
- get rid of useless/idempotent add/remove of nodes that don't change
the DOM.
- ensure that node attributes post-restructuring are correct.

This patch fixes a tokenizer syntax error encountered on
[[:en:Template:JacksonvilleWikiProject-Member]] and [[:en:Template:Infobox
former country]] by allowing optional whitespace before start-of-line template
syntax.

254 round-trip tests (up from 184) are now passing.
Also:
* tweaked runtests.sh slightly (use less -R instead of -r).
* made sure the EOFTk is preserved in phase 3 transforms

- This is implemented as a post-processing pass.
- Might require additional checks to verify rewriteability.
- Implemented as a pair-wise tag DOM minimization strategy,
i.e. it takes tag pairs (B, I) for ex, and attempts to
normalize the tree just for those tag pairs. Normalizing
across multiple tags is implemented as pairwise rewriting
across all pairs: Ex:(b,i), (b,u),(i,u) for (b,i,u)
- Copied over attributes as part of rewriting, but some of the
attributes lose their meaning on rewriting since tags are
reordered (ex: sourcePosn, sourceTagPosn). How do we handle this?
Output examples and possible issues to fix:
<i><b><u>biu</u></b></i><b><u>bu</u></b><u>u</u>
gets rewritten to:
<u><b><i>biu</i>bu</b>u</u>
But, the equivalent wikitext form:
'''''<u>biu</u>''''''''<u>bu</u>'''<u>u</u>
does not get rewritten because of parsing differences.
This wikitext gets parsed into:
<i><b><u>biu</u>'''</b></i><u>bu<b>u</b></u>
The extra ''' token in the middle thwarts DOM rewriting.
However, a slightly different version:
"'''''<u>biu</u>''<u>bu</u>'''<u>u</u>"
gets properly normalized to:
<u>'''''biu''bu'''u</u>
An alternative, but fun strategy to play with is to use the following
two normalization primitives: S(wap) and M(erge).
- S rewrites T1(T2(x)) into T2(T1(x))
(ex: <b><i>foo</i></b> ==> <i><b>foo</b></i>)
- M rewrites (T(x),T(y)) into (T(x,y)).
(ex: <b>foo</b><b>bar</b> ==> <b>foobar</b>)
The current rewriting strategy could possibly be re-implemented as S-M
rewriting. The problem to solve there would be to find an efficient
rewriting strategy that is guaranteed to lead to a normal form. I may
not play with it now, but just documenting it for later (to play with
in my spare time).
This commit is just as a record of fun/experimental code where I get to
learn details of JS, wikitext, parsing, and DOM manipulation. Next
version of this code will attempt to introduce minimal DOM restructuring
across multiple tags at once which can be more efficient.
gwicke: Removed now passing test from whitelist, and updated another whitelist
entry which is now improved.

* Added a generic stx_v 'syntax variant' round-trip attribute
* For pre, use stx:'html' vs. no syntax annotation. This might not be 100%
safe for arbitrary html input, so we might want to flip this to stx:'wiki'
later.
* 181 round-trip tests passing

* Very basic support attribute key-value pairs emitted from templates
* Add TALKPAGENAME stub implementation
* Only show 'no revisions' message for top-level pages

* After installing Parsoid (sudo npm install -g in modules/parser), run 'node
server.js' from the api directory and navigate to http://localhost:8000/ and
follow the directions. You can start to navigate the English wikipedia at
http://localhost:8000/Main_Page, or manually enter wikitext or HTML DOM to
convert.
* Uses the express framework, could also use just connect
* Uses the cluster module to manage workers per-core and restart those on
failure

* Changed RDFa for links according to
http://www.mediawiki.org/wiki/Parsoid/RDFa_vocabulary
* Added basic support for internal/external link serialization
* Moved numbering of external links from tokenizer to LinkHandler
* Added round-tripping for generic HTML tags
* Replaced nowiki tag with <meta typeOf="mw:tag" content="nowiki"> and <meta
typeOf="mw:tag" content="/nowiki"> for now.
* 154 round-trip tests passing (node parserTests.js --roundtrip).
Change-Id: I16c4db21b1b543ee57c73e569c83025b64664542
* added stx: 'html' round-trip information for html tags
* added t_stx: 'row' info for row-wise table wiki syntax, and support for it

* the first table row is implicit in wikitext
* renamed lastToken to prevToken in serializer
* strip first newline in an initial chunkCB
