Catrope ac6c9b2418 Specify (but do not implement) the context parameter to toDataElement()
This allows the converter to provide the node handlers with context
information, which hybrid nodes (such as alien and meta) need to decide
which shape to take.

Trevor Parscal 16310f7535 Added tests and fixed inconsistencies for empty text node handling
Continues where Ibb682332a6084e357104183641a104e3ae1e253f left off, adding tests and removing inconsistencies between the behavior of the document constructor, which was adding empty text nodes to empty paragraphs, and correcting other tests which expected empty text nodes to be there as well.

Trevor Parscal ea4b42b2b2 Automatically prune empty text nodes
When there's 2 entities or inline content nodes (like aliens) with text between them, removing that text should remove the node too. If you don't remove the node then CE won't think to make a slug between the two inline nodes.

Catrope d73d6e9bf0 Add extension-specific types functionality to ModelRegistry
Extension-specific types are RDFa types (or type regexes) that are
registered with the ModelRegistry separately. If an element has a type
that is extension-specific, then that element can only be matched by a
rule that asserts one of its extension-specific types.

For MediaWiki, we would call
ve.dm.modelRegistry.registerExtensionSpecificType(/^mw:/ ) .
So then an element like <span typeof="mw:foobar"> would either match a
rule specifically for mw:foobar, if one exists, or no rule at all; even
the rule for <span> would not match. The consequence of this is that
elements with unrecognized mw:-prefixed RDFa types are alienated.

This won't usefully register the node with the converter right now, but
we need to allow this because the ModelFactory tests will need to have
stub nodes with tag-only matches.

Trevor Parscal 6f8b0965f2 Remove range.normalize (not needed), use range.isCollapsed more often
The normalize method doesn't need to be explicitly called anymore because there's not any code that changes the properties of a range directly anymore.

A good way to prove it's not needed anymore is to move the normalization logic to the constructor and then add "console.log(this.from <= this.to );" to the normalize method - you will find that it's never actually doing anything at all because the range was normalized by the constructor.

ve.Range
* Moved normalization logic to constructor
* Removed calls to normalize method
* Removed normalize method
* Simplified documentation for flip method
* Whitespace fixes

ve.Document, ve.dm.Transaction, ve.dm.Surface, ve.dm.Document, ve.ce.Surface
* Removed calls to range.normalize
* Switched to using range.isCollapsed instead of comparing properties directly

  -> (removed)
* Warning: ve.LeafNode.js:21: {@link ve.Node#hasChildren} links to non-existing member
  -> (removed)

Differences fixed:
* Variadic arguments are like @param {Type...} [name]
  instead of @param {Type} [name...]
* Convert all file headers from /** to /*! because JSDuck tries
  to parse all /** blocks and fails to parse with all sorts of
   errors for "Global property", "Unnamed property", and
  "Duplicate property".
  Find: \/\*\*([^@]+)(@copyright)
  Replace: /*!$1$2
* Indented blocks are considered code examples.
  A few methods had documentation with numbered lists that were
  indented, which have now been updated to not be intended.
* The free-form text descriptions are parsed with Markdown,
  which requires lists to be separated from paragraphs by an
  empty line.
  And we should use `backticks` instead of {braces} for inline
  code in text paragraphs.
* Doc blocks for classes and their constructor have to be
  in the correct order (@constructor, @param, @return must be
  before @class, @abstract, @extends etc.)
* `@extends Class` must not have Class {wrapped}
* @throws must start with a {Type}
* @example means something else. It is used for an  inline demo
  iframe, not code block. For that simply indent with spaces.
* @member means something else.
  Non-function properties are marked with @property, not @member.
* To create a link to a class or member, in most cases the name
  is enough to create a link. E.g. Foo, Foo.bar, Foo.bar#quux,
  where a hash stands for "instance member", so Foo.bar#quux,
  links to Foo.bar.prototype.quux (the is not supported, as
  "prototype" is considered an implementation detail, it only
  indexes class name and method name).
  If the magic linker doesn't work for some case, the
  verbose syntax is {@link #target label}.
* @property can't have sub-properties (nested @param and @return
  values are supported, only @static @property can't be nested).
  We only have one case of this, which can be worked around by
  moving those in a new virtual class. The code is unaltered
  (only moved down so that it isn't with the scope of the main
  @class block). ve.dm.TransactionProcessor.processors.

New:
* @mixins: Classes mixed into the current class.
* @event: Events that can be emitted by a class. These are also
  inherited by subclasses. (+ @param, @return and @preventable).
  So ve.Node#event-attach is inherited to ve.dm.BreakNode,
  just like @method is.
* @singleton: Plain objects such as ve, ve.dm, ve.ce were missing
  documentation causing a tree error. Documented those as a
  JSDuck singleton, which they but just weren't documented yet.
  NB: Members of @singleton don't need @static (if present,
  triggers a compiler warning).
* @chainable: Shorthand for "@return this". We were using
  "@return {classname}" which is ambiguous (returns the same
  instance or another instance?), @chainable is specifically
  for "@return this". Creates proper labels in the generated
  HTML pages.

Removed:
* @mixin: (not to be confused with @mixins). Not supported by
  JSDuck. Every class is standalone anyway. Where needed marked
  them @class + @abstract instead.

Catrope 7bcf35e0e8 (bug 43056) Inline tags like <span> are block-alienated sometimes
This happens when the <span> is the start of unwrapped content. The
converter logic to look at the tag name in wrapping mode doesn't kick in
because we're not yet in wrapping mode at that point.

The core issue was that previously, we relied on the document
structure/state to choose between alienBlock and alienInline, and only
used the tag name where the document structure was ambiguous (wrapping).
Changed this to be the other way around: we now rely primarily on the
tag name, and if that doesn't match what we expect based on the document
structure, we work around that if possible. Specifically:
* inline tag in our wrapper --> inline alien
* block tag in our wrapper --> close wrapper, block alien
* inline tag in wrapper that's not ours --> inline alien
* block tag in wrapper that's not ours --> *inline* alien
* inline tag in structural location --> open wrapper, inline alien
* block tag in structural location --> block alien
* inline tag in content location --> inline alien
* block tag in content location --> *inline* alien
only in the fourth and the last case do we need to use the "wrong" alien type to
preserve document validity, and it will always be inline where block was
expected, which should reduce UI issues.

The condensed version of the above, which is used in the code, is:
* If in a non-wrapper content location, use inline
* If in a wrapper that's not ours, use inline
* Otherwise, decide based on tag name
* Open or close wrapper if needed

ve.dm.Converter:
* Replace isInline logic in createAlien() with the above
* Factor out code to start wrapping (was duplicated) into startWrapping()
* Call startWrapping() if createAlien() returns an alienInline and we're
  in a structural location

Tests:
* Add test cases with aliens at the start and end of unwrapped content
** The first one failed prior to these changes and now passes, the
   second one was already passing
* Fix about group test case, was exhibiting the bug that this commit fixes

Timo Tijhof 4fa57b469a Phase out $.toJSON, use JSON.stringify directly.
Although $.toJSON optimises heavily for modern browsers (it
becomes a direct reference to JSON.stringify), we still load the
extra plugin.

JSON is specified as part of ECMAScript 5, but most browsers
supported this one before they supported the rest of ES5.

http://caniuse.com/#search=JSON

Cut off for native JSON is IE7, Firefox 3.0 (3.6 supports it) and
Safari 3. Not any of our concern as VE will most likely never
support those (certainly not at this point in time, and less
likely as time goes on).

Catrope 045b597253 Fix the "list of US Presidents" bug
I noticed this bug on [[List of Presidents of the United States]]. When
there's HTML that looks like "<td>Foo\n<meta/></td>", the converter will
collect the newline in wrappedWhitespace, then attempt to splice it out
and store it in internal data. But instead, it ends up splicing out the
/metaBlock element, which causes strange unbalanced input, which causes
an empty table in the node tree.

Trevor Parscal 353297e5b5 (bug 42925) Inspector doesn't open properly
ve.Range
* Rewrote truncate so that it works as expected, truncation should always reduce the length using the start/end values, not the from/to values

ve.ui.Inspector
* Added a comment about where the name argument to onBeforeInspectorOpen comes from, since it's a little bit confusing on first read (and I wrote it!)
* Calling onInitialize, onOpen and onClose methods directly, since we need to control the before or after-ness of listeners getting in there and doing their stuff - plus it's more direct
* Removed onRemove stub, which is never actually called
* Added before/after versions of initialize, open and close events
* Got rid of recursion guard since we don't need it anymore thanks to changes made in ve.dm.Surface (see below)

ve.ui.Context
* Updated event names to deal with new before/after naming of initialize, open and close events
* Removed fade-in logic since fading in doesn't even work anymore - since now we now annotate first, then open the inspector, the menu will actually exist and be open when we open the inspector even though you don't see it because it's quickly obscured

ve.ui.LinkInspector
* Made fragments non-auto selecting, in the case of onInitialize we actually call select(), which is silly since we were using an auto-selecting fragment - it's clear that this was a mistake

ve.dm.Surface
* Moved locking (polling stop and start) to the far outside edges of the change method
* I need a lot of eyes and testing on this change, it seems OK to me, but I'm suspicious that it may have side effects
* What was happening is that selection changes were being applied and then the poll was picking them up, and then the selection was coming in again as a change, but it wasn't a change at all, it was just feedback - this change event was then closing the inspector the instant it was opened - the odd part was that this only occurred when you selected backwards, which seems to be caused by the range being normalized, so it looked like a new selection even though it wasn't

ve.dm.Document
* trimOuterSpace from Range didn't consider annotated spaces to be spaces, by using the [0] trick (first character of a plain text character string or first element in an annotated character's array both are the character's value - but elements don't have a property named '0' so it skips those safely as well) we can always get the right value for comparison

Trevor Parscal 7450fa9114 (bug 42836) Formatting drop-down updates
The fix for bug 40339 supposedly modified when we emit contextChange events so that when the node changed, even if the context was the same, we consider it a context change (such as changing the heading level).

Unfortunately I was mentally absent when I wrote the patch and all it actually does it emit more select events.

Basically cb4877b0d0 - which does indeed fix the bug - doesn't do what it's commit message describes, but this fixes it.

Trevor Parscal 42de94fc44 (bug 42298) Handle URL encoding in MWInternalLinkAnnotation
* Decode titles we get from Parsoid
* Encode titles we give to Parsoid
* Preserve the original encoded title if nothing meaningful changed (a.k.a. do not normalize unless we must)

Catrope 085a6f0985 (bug 42487) Don't crash the converter for "<span>\n<p>Foo</p></span>"
The converter was misbehaving when handling <p>s inside <span>s. This
can't be expressed in the linmod, but it would try to anyway. <span><p>
would result in too many paragraph closing elements, leading to an
exception in ve.dm.Document complaining about unbalanced input.
<span>\n<p> would result in an exception in the converter itself while
trying to perform whitespace preservation on the newline.

This change makes the converter detect these scenarios and alienate the
offending node. So <span><p>Foo</p></span> converts to a wrapper
paragraph containing an alienInline whose HTML is "<p>Foo</p>" and which
is annotated with a TextStyleSpanAnnotation.

ve.dm.Converter.getDomFromData():
* Change the criteria for alienBlock vs alienInline
** Only infer from the node type if we're in wrapping mode AND we're at
   the same level where the wrapping started (wrappingIsOurs). If the
   latter isn't the case, we can't split the wrapper in the block case
   because we're at the wrong level.
** Use alienInline not only if the branch is a content branch, but also
   if there are active annotations. This catches e.g. <li><b><p>
   (and generally <span><p> on the top level).
* Before converting a child element, check that the child isn't "bad".
  Bad children are non-content children in content branches, and
  non-content children encountered within a wrapper that we can't split.
  Only good children are converted, and bad children are alienated (cue
  Santa/Sinterklaas jokes).
* Add childIsContent and rename branchIsContent to branchHasContent

Trevor Parscal 9a7b0eafb6 Merge "(bug 42469) Leading newlines in <pre>s get eaten" 2012-12-04 01:16:25 +00:00
Catrope e95cc34978 (bug 42469) Leading newlines in <pre>s get eaten
HTML DOM has annoying behavior for <pre>s where .innerHTML eats the
first newline in a <pre>. Work around this by explicitly adding a
newline in the data->DOM converter if the <pre> already contained a
newline.

There is a separate bug in Parsoid that causes the newline to be lost
anyway, filed as bug 42666
