Gabriel Wicke 08b5ed1a43 Use _inNewlineContext method instead of bare onNewline
This makes sure that we escape start-of-line syntax when needed, since
onNewline is often not yet set.

Discussion / background:
[19:18] <subbu> this will fix it, but, i think this is asking for another
minor refactoring of these flags ... because this is a subtle fix which means
it might be possible to make it clearer.  onNewline is one true in on
direction, i.e. if true, we are in a new line state, but if we are in a
newline context, onNewline is not true, which is why this new method is
needed.
[19:19] <subbu> i dont know if it is possible, but it seems like it shoudl be
possible.  but, something for later.
[19:20] <subbu> badly phraed.  "onNewline" ==> in new line context, but if in
new line context, onNewline may be false.
[19:20] <gwicke> we should perhaps update it as early as possible instead
[19:21] <subbu> i cannot today, but possible monday.  i am heading out in
about 15-30 mins.
[19:22] <gwicke> will need to check all conditions depending on it in
_serializeToken
[19:22] <subbu> oh, i misunderstood you :)
[19:22] <gwicke> and if there are cases where the onNewline / onStartOfLine
state could be reverted later
[19:23] <subbu> you were referring to the flag, i thought you meant we should
fix this sooner than later.
[19:23] <gwicke> yes, I wasn't terribly clear
[19:23] <gwicke> you wrote something about following productions swallowing
newlines, but I think we don't actually do that any more
[19:24] <gwicke> I'm quite optimistic that updating those flags much earlier
would work
[19:25] <subbu> yes, it could fix it.
[19:26] <subbu> you might be right reg. swallowing.  it was happening earlier.
but, not right now, after single-line mode and other fixes.

Gabriel Wicke d4dc8d86d9 Entity-escape [<>] in text content
This should not really be needed if the tokenizer did not decode html entities
on the fly. It is still a quick way to make sure no htmlish content can be
inserted even with the current decoding.

The next step and proper fix is to make entity decoding either optional in the
tokenizer (flag-controlled), or move it to a later stage in the token
processing pipeline.

Gabriel Wicke b3bd2ffe8d Fix definition list parsing and round-trip single vs. multi-line dt/dd
* Removed murky ' :' -> '&nbsp;:' replacement in tokenizer. This breaks four
  parser tests, and should be fixed in a token stream transformer or DOM
  postprocessor. This replacement clashes with round-tripping, and is not
  terribly important visually.
* Added stx:row annotation to single-line dt/dd pairs and use it to preserve
  single-line syntax in the serializer. There is no attempt yet to support the
  addition of nested lists in an originally single-line dd. We'd need to look
  ahead in the serializer to support this. Perhaps the editor can simply drop
  data-mw in that case.
* Switched default dt/dd serialization to multi-line. This supports all nested
  lists and multiple dds.
* Don't close dls when switching from dt to dd or back in the token stream
  ListHandler.

Overall 290 round-trip tests are passing now (up from 284, some due to &nbsp;,
some due to lists). The number of passing parser tests dropped slightly from
303 to 297 (or 301/295 on weekdays other than Thursday).

Gabriel Wicke e584e35ecb Improve nested definition list serialization
Basically only prefix all bullets if the serialization output is going to be
in start-of-line context. The test for that is currently inline, but should
perhaps be factored out to a method or state flag instead.

We could alternatively consider to return the start-of-line prefix and let it
be used in _serializeToken in case we end up in start-of-line context.

This patch also fixes a newline issue on input like this:

:d1
::: d3

Both the list and list item handlers now set the startsNewline flag
dynamically depending on the context, so that we don't depend on the
suppression of newlines from list syntax by the singleLineMode any more.

There is still an extra newline inserted between list items in the following
example:

;t1 :d1
;;t2 ::d2

This looks like a bug in the produced DOM and not in the serializer, since the
outer definition list is closed and re-opened between d1 and t2.

Gabriel Wicke cf32b34b0a First attempt at the definition list bug (work in progress)
The main issue is that the bullets from dd/dt were not stored on the stack. I
added a separate field for it in each stack entry, which now fixes the basic
indent case without (afaik) breaking anything else.

There are still some newline issues, and the need to handle the single-line
dd/dt vs. the multi-line variant.

* Protect indent-pre content from start-of-line syntax escaping
* Preserve extra leading spaces in the tokenizer

Gabriel Wicke 6054a4aa14 Clean up serializer newline handling a bit further
Queued newlines and new trailing newlines were not cleanly separated so far,
which caused some trailing newlines to be consumed for needed leading
newlines. This change fixes several newline bugs, taking the number of passing
round-trip tests from 276 back up to 282.

Gabriel Wicke e117f09362 Wikitext escaping and quite complete source range tracking
* Started to add more complete tag source range (tsr) annotations to most
  start / empty tags. These replace the old sourcePos and sourceTagPos
  annotations, and look more promising for general round-tripping than block
  source ranges (bsr). See
  http://www.mediawiki.org/wiki/User:GWicke/Parsoid_source_ranges for some
  notes on this.
* Added an escapeWikitext method in the serializer that tokenizes supposedly
  text-only content from the DOM with the tokenizer and wraps runs of returned
  non-text tokens into nowiki tags. The source corresponding to non-text
  tokens is retrieved using the tsr annotations.
* Removed old (unused) table productions to avoid confusion.
* 276 round-trip tests are passing, vs. 283 without escaping.

Known issues:
* harmless for now, can be improved later: urllinks in external link captions
  are wrapped in nowiki. Example HTML:

<a rel='mw:extLink' href="http://example.com">http://example2.com</a>

* some start-of-line syntax in wiki-syntax preformatted blocks might be
  wrapped into nowiki when that would not really be needed. Example HTML DOM:

<pre>
* foo
* bar
</pre>

Gabriel Wicke 5fbc80321b Improve newline handling for comments and nowiki/noinclude tags
* Added a newlineTransparent flag to handlers that prevents changes to the
  onNewline status, so that content following it is still considered to be in
  start-of-line context. This fixes a few rt tests where a comment or nowiki
  tag is at the start of the line, and following content should end up on the
  same line.
* 283 rt parser tests are now passing.

* added a generic singleLine mode for single-line syntactical environments
* switched the web service to line-based diffs to avoid issues when diffing
  the round-trip results of [[:en:Programming language]]
* 280 round-trip tests are passing now

Gabriel Wicke 41d8212573 Emit SpaceCharacters token for HTML5 'space' chars
HTML5 defines space characters as [ \r\n\t\f] in
http://www.whatwg.org/specs/web-apps/current-work/multipage/common-microsyntaxes.html#space-character.
It treats these specially in a few contexts. As an example, the foster
parenting algorithm does not apply to space characters.

As a result, this change fixes the round-tripping of spaces between table
tags, which were previously moved before the table.

Subramanya Sastry c0fc9e9a97 Updated newline handling around lists and nested lists.
- Something like this:
    <ul><li>1</li><li>2<ul><li>2.1</li><li>2.2<ul><li>2.2.1</li><li>2.2.2</li></ul></li><li>2.3</li></ul></li><li>3</li></ul>
  now serializes properly to:

    *1
    *2
    **2.1
    **2.2
    ***2.2.1
    ***2.2.2
    **2.3
    *3

  So does this form which is what the above wikitext parses to:
    <ul><li>1
    </li><li>2
    <ul><li>2.1
    </li><li>2.2
    <ul><li>2.2.1
    </li><li>2.2.2
    </li></ul></li><li>2.3
    </li></ul></li><li>3
    </li></ul>

- Lists (and nested lists) are not entirely newline-insensitive.
  They still depend on newlines *between* lists.  The opening
  <ul> tag for non-nested lists should always start on a new line.
  So, for example,
    <ul><li>foo</li></ul><ul><li>bar</li></ul>
  will serialize to:
    *foo
    *bar
  which is incorrect.  But,
    <ul><li>foo</li></ul>
    <ul><li>bar</li></ul>
  will correctly serialize to:
    *foo

    *bar

Subramanya Sastry d7e83c4e2b Fixed/updated newline handling for <p> tags
- More pieces are now simplified and all(?) newline handling
  is now centralized in the serializeToken function.

- This commit fixes bugs in rt-ing some code snippets
    ----------
    Ex 1: foo<p>bar</p>baz
    ----------

- This commit fixes bugs serializing VE generated html
    ----------
    Ex 2: <p>foo</p><pre>bar</pre> ==> foo\n bar
    ----------

- But, this round of fixes introduces RT failures for certain
  code examples in parserTests.txt.  In all these failing cases,
  inline text/html is embedded within a generated <p> tag during
  parsing.  If these generated <p> tags can have a "gc:1" attribute
  added to them, we can properly serialize them to the original
  form.
    ----------
    Ex 3: foo<pre>bar</pre>
          Parsed HTML: <p>foo</p><pre>bar</pre>
    ----------
  Note how this parsed HTML is identical to what the VE outputs
  in Example 2 above.  So, without the gc:1 attribute, we now
  have conflicting requirements on the example same HTML.
  This increases confidence in the correctness of my commit here.

Subramanya Sastry 51227f2a4a Improved, simplified newline handling in wikitext serializer.
- Eliminated newline handling from several places in code and
  mostly isolated it to serializeToken thus simplifying newline
  handling logic.
- Fixing some bugs in the process: # of green roundtrip tests
  went up by 5 (294 --> 299) but actually introduced failures on
  a few originally succeeding tests (additional leading/trailing
  newlines on the entire test output).
- Added bonus: made list serializing (mostly) insensitive to
  newlines between tags.  So, all the following DOM serialize
  identically to the following wikitext:

  *foo
  *bar

  ----------
  <ul><li>foo</li><li>bar</li></ul>

  <ul>
  <li>foo</li>

Gabriel Wicke 2fa5baabbb Make it easier to configure the default wiki, and add support for mediawiki.org
* mw:Foo now loads pages from mediawiki.org
* The default prefix still is 'en'. You can switch this to 'mw' in ParserService.js.

Subramanya Sastry b665a2558f Fixed bugs handing/transforming quotes
- Three bugs that were messing up quote transformations.
- Now, the following cases are handled properly:

  * ''foo'''
  * '''foo''
  * ''foo''''
  * ''''foo''

  These tests (and other quote tests) have to be added to core parser
  tests file.

- One more parser test green.

Gabriel Wicke a146fcb8ad Improve the handling of newlines for round-tripping
An improvement, but there still are some extra newlines inserted after
paragraphs. Example input:

-------

Foo:
{|
|foo
|}
-------

Extra newlines are inserted after the Foo: and the foo in the table. They are
not fed as tokens or text to the tree builder, so there is likely a bug in the
html5 library or JSDom.
