The EventEmitter API we inherited from Node.js and then bastardized was
getting awkward and cumbersome. The number of uses of ve.bind was getting
out of control, and removing events meant caching the bound method in a
property. Many of the "features" of EventEmitter wasn't even being used,
some causing overhead, others just causing bloat. This change cleans up
how EventEmitter is used throughout the codebase.
The new event emitter API includes:
* emit - identical to the previous API, no longer throws an error if you
emit error without a handler
* once - identical to the previous API, still introduces a wrapper* on -
compatible with the previous API but has some new features
* off - identical to removeListener in the previous API
* connect - very similar to addListenerMethods but doesn't wrap callbacks
in closures anymore
* disconnect - new, basically the opposite of addListenerMethods
Another change that is made in this commit is mixing in rather than
inheriting from EventEmitter.
Finally, there are changes throughout the codebase anywhere
connect/disconnect could be used.

By removing the transaction listeners from surface fragments we
no longer have to make sure they are always manually destroyed.
In order to retain the functionality of having fragments update
with transactions elsewhere we keep a pointer to a place in the
new complete history stack in the surface. The complete history
stack records all transactions, even undone ones.
Whenever getRange is called we replay all transactions in the
complete history (in the correct order) since the fragment was
last updated.
Also in this commit:
* Updated Format/IndentationAction to test undo(). This increases
coverage of surface fragment behaviour.
* .range is always accessed by .getRange now, although as an
optimisation we can use the noCopy mode when we a sure the
returned range will not be modified.
* Added undo test to .update (previously .onTransact)
Bug: 47343

So. It turns out that the design of SurfaceFragment is a little -
shall we say - wonky.
One of the best things about ve.dm.SurfaceFragment is its magical
ability to retain the intention of its range, even as transactions
are being processed. This ability is granted by each fragment
listening to the surface's change event, and responding by using
translateRange for each transaction that gets processed. Surface
fragments also have these clever methods that allow you to get a
fragment based on another, which makes adjusting the range easy to do
inline without having to manually store multiple fragments or
modifying the original.
This sounded good, and we seemed to all be convinced it was well
designed. But if you add a console.log( 'hello' ); to the first line
of ve.dm.SurfaceFragment.prototype.onTransact, and then start using
the bold tool on various selections of text, you will find that there
may indeed be a flaw. What you will probably realize is that the
number of times that particular line of code is being called is
disturbingly large, and increases each time you do just about anything
in the editor. What's going on? How did we get here? Read on…
It turns out that fragments are immortal. We create them, they listen
to the surface's transact event, we are done with them, but the
surface keeps on emitting events to the now long forgotten about
fragments. They continue to build up over time, never go out of scope,
and bloat the hell out of our program.
The same ended up being true of toolbars - and each time the context
menu fired up a new one the old one was left in limbo, still
responding to events, still taking up memory, but not being visible to
the user.
All of this immortality was causing strange and difficult to track
down problems. This patch fixes this by introducing a destroy method.
This method unbinds events, allowing the object to finally fall out of
scope and die - and more importantly stop receiving notifications of
changes.
This is a hack, but Ed will no doubt get this situation sorted out
properly by making fragments lazy-evaluate their selections by only
storing an identifier of the most recent transaction they were based
on, see bug 47343.

Added filter for nodes being passed to update state event - this
ensures that nodes are not being included with zero-length coverage, a
side effect of how selectNodes handles the virtual boundaries of text
nodes.

Created an IndexValueStore class which can store any object and return
an integer index to its hash map.
Linear data is now stored in ve.dm.LinearData instances. Two subclasses
for element and meta data contain methods specific to those data types
(ElementLinearData and MetaLinearData).
The static methods in ve.dm.Document that inspected data at a given
offset are now instance methods of ve.dm.ElementLinearData.
AnnotationSets (which are no longer OrderedHashSets) have been moved
to /dm and also have to be instantiated with a pointer the store.

* Document them consistently between secetions Inheritance and
Static Properties under their own (new) section Events.
* Removed any quotes or brackets around the event name in existing
@emit annotations
Search: @emit.*['"{}(){}]
* For every call to this.emit() anywhere, added @emits.
* Fixed all warnings for references to undefined events
(introduced as a result of the previous point).
Event handler parameter documented based on the emit() call
and actual handlers using the event. Usually the latter is
more elaborate.
* Extend coverage of jQuery as needed
(copied from mwcore/maintenance/jsduck/external.js
written by me, hereby implicitly and explicitly released under MIT).
Specifics
* ve.ce.Surface#onContentChange: Fixed type of range from Object to ve.Range.
* ve.ce.SurfaceObserver#poll: Fix syntax for code from {} to `backticks`.
* ve.ui.Toolbar#onContextChange: Doesn't actually emit "clearState" event.
Removed #onClearState in Tool, ButtonTool and DropdownTool.

This is a major refactor of user interface context, frame, dialog
and inspector classes, including adding several new classes which
generalize managing inspectors/dialogs (which are now subclasses
of window).
New classes:
* ve.ui.Window.js - base class for inspector and dialog classes
* ve.ui.WindowSet.js - manages mutually exclusive windows, used
by surface and context for dialogs and inspectors respectively
* ve.ui.DialogFactory - generates dialogs
* ve.ui.IconButtonWidget - used in inspector for buttons in the head
Refactored classes:
* ve.ui.Context - moved inspector management to window set
* ve.ui.Frame - made iframes initialize asynchronously
* ve.ui.Dialog and ve.ui.Inspector - moved initialization to async
initialize method
Other interesting bits:
ve.ui.*Icons*.css, *.svg, *.png, *.ai
* Merged icon stylesheets so all icons are available inside windows
* Renamed inspector icon to window
ve.ui.*.css
* Reorganized styles so that different windows can include only
what they need
* Moved things to where they belonged (some things were in strange places)
ve.init.Target.js, ve.init.mw.ViewPageTarget.js, ve.init.sa.Target.js
* Removed dialog management - dialogs are managed by the surface now
ve.ui.*Dialog.js
* Renamed title message static property
* Added registration
ve.ui.*Inspector.js
* Switch to accept surface object rather than context, which conforms
to the more general window class without losing any functionality
(in fact, most of the time the surface was what we actually wanted)
ve.ui.MenuWidget.js, ve.ui.MWLinkTargetInputWidget.js
* Using surface overly rather than passing an overlay around
through constructors
Change-Id: Ifd16a1003ff44c48ee7b2c66928cf9cc858b2564
* Made method descriptions imperative: "Do this" rather than "Does this"

* Normalized use of package names throughout
* Normalized class descriptions
* Removed incorrect @abstract tags
* Added missing @method tags
* Lots of other minor cleanup

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.

The contextChange event is fired when:
* Changes to insertion annotations
* Changes to which nodes are selected (start/end nodes have changed)
* Attributes have changed on any element (it's probably more expensive to detect if the changes are relevant than to just emit the event and let listeners do their thing)
This fixes most of the strange behavior with the toolbar not updating properly.

* Rewrite of all tools, dramatically simplifiying them and decreasing

* For the most common case:
- replace ve.extendClass with ve.inheritClass (chose slightly
different names to detect usage of the old/new one, and I
like 'inherit' better).
- move it up to below the constructor, see doc block for why.
* Cases where more than 2 arguments were passed to
ve.extendClass are handled differently depending on the case.
In case of a longer inheritance tree, the other arguments
could be omitted (like in "ve.ce.FooBar, ve.FooBar,
ve.Bar". ve.ce.FooBar only needs to inherit from ve.FooBar,
because ve.ce.FooBar inherits from ve.Bar).
In the case of where it previously had two mixins with
ve.extendClass(), either one becomes inheritClass and one
a mixin, both to mixinClass().
No visible changes should come from this commit as the
instances still all have the same visible properties in the
end. No more or less than before.
* Misc.:
- Be consistent in calling parent constructors in the
same order as the inheritance.
- Add missing @extends and @param documentation.
- Replace invalid {Integer} type hint with {Number}.
- Consistent doc comments order:
@class, @abstract, @constructor, @extends, @params.
- Fix indentation errors
A fairly common mistake was a superfluous space before the
identifier on the assignment line directly below the
documentation comment.
$ ack "^ [^*]" --js modules/ve
- Typo "Inhertiance" -> "Inheritance".
- Replacing the other confusing comment "Inheritance" (inside
the constructor) with "Parent constructor".
- Add missing @abstract for ve.ui.Tool.
- Corrected ve.FormatDropdownTool to ve.ui.FormatDropdownTool.js
- Add function names to all @constructor functions. Now that we
have inheritance it is important and useful to have these
functions not be anonymous.

Refactor:
* ve.indexOf
Renamed from ve.inArray.
This was named after the jQuery method which in turn has a longer
story about why it is so unfortunately named. It doesn't return
a boolean, but an index. Hence the native method being called
indexOf as well.
* ve.bind
Renamed from ve.proxy.
I considered making it use Function.prototype.bind if available.
As it performs better than $.proxy (which doesn't use to the native
bind if available). However since bind needs to be bound itself in
order to use it detached, it turns out with the "call()" and
"bind()" it is slower than the $.proxy shim:
http://jsperf.com/function-bind-shim-perf
It would've been like this:
ve.bind = Function.prototype.bind ?
Function.prototype.call.bind( Function.prototype.bind ) :
$.proxy;
But instead sticking to ve.bind = $.proxy;
* ve.extendObject
Documented the parts of jQuery.extend that we use. This makes it
easier to replace in the future.
Documentation:
* Added function documentation blocks.
* Added annotations to functions that we will be able to remove
in the future in favour of the native methods.
With "@until + when/how".
In this case "ES5". Meaning, whenever we drop support for browsers
that don't support ES5. Although in the developer community ES5 is
still fairly fresh, browsers have been aware for it long enough
that thee moment we're able to drop it may be sooner than we think.
The only blocker so far is IE8. The rest of the browsers have had
it long enough that the traffic we need to support of non-IE
supports it.
Misc.:
* Removed 'node: true' from .jshintrc since Parsoid is no longer in
this repo and thus no more nodejs files.
- This unraveled two lint errors: Usage of 'module' and 'console'.
(both were considered 'safe globals' due to nodejs, but not in
browser code).
* Replaced usage (before renaming):
- $.inArray -> ve.inArray
- Function.prototype.bind -> ve.proxy
- Array.isArray -> ve.isArray
- [].indexOf -> ve.inArray
- $.fn.bind/live/delegate/unbind/die/delegate -> $.fn.on/off

* Restricting "camelcase":
No changes, we were passing all of these already
* Explicitly unrestricting "forin" and "plusplus"
These are off by default in node-jshint, but some distro of jshint
and editors that use their own wrapper around jshint instead of
node-jshint (Eclipse?) may have different defaults. Therefor
setting them to false explicitly. This also serves as a reminder
for the future so we'll always know we don't pass that, in case
we would want to change that.
* Fix order ("quotemark" before "regexp")
* Restricting "unused"
We're not passing all of this, which is why I've set it to false
for now. But I did put it in .jshintrc as placeholder.
I've fixed most of them, there's some left where there is no clean
solution.
* While at it fix a few issues:
- Unused variables ($target, $window)
- Bad practices (using jQuery context for find instead of creation)
- Redundant /*global */ comments
- Parameters that are not used and don't have documentation either
- Lines longer than 100 chars @ 4 spaces/tab
* Note:
- ve.ce.Surface.prototype.onChange takes two arguments but never
uses the former. And even the second one can be null/undefined.
Aside from that, the .change() function emits
another event for the transaction already. Looks like this
should be refactored a bit, two more separated events probably
or one that is actually used better.
- Also cleaned up a lot of comments, some of which were missing,
others were incorrect
- Reworked the contentChange event so we are no longer using the
word new as an object key; expanded a complex object into multiple
arguments being passed through the event to make it easier to work
with and document

* Various JSHint warnings.
* Whitespace
* jQuery(): Use '<tag>' for element creation,
use '<valid><xml/></valid>' for parsing
* Use the default operator instead of ternary when the condition and
first value are the same.
x = foo ? foo : bar; -> x = foo || bar;
Because contrary to some programming language (PHP...), in JS the
default operator does not enforce a boolean result but returns the
original value, hence it being called the 'default' operator, as
opposed to the 'or' operator.
* No need to call addClass() twice, it takes a space-separated list
(jQuery splits by space and adds if needed)
* Use .on( event[, selector], fn ) instead of the deprecated
routers to it such as .bind(), .delegate() and .live().
All these three are now built-in and fully compatible with .on()
* Add 'XXX:' comments for suspicious code that I don't want to change
as part of a clean up commit.
* Remove unused variables (several var x = this; where x was not
used anywhere, possibly from boilerplate copy/paste)
* Follows-up Trevor's commit that converts test suites to the new
