* Replaces c8b4a28936
* Use Object() casting to detect objects instead of .constructor
(or instanceof). Both .constructor and instanceof compare by reference
the type "Object" which means if the object comes from another window
(where there is a different "Object" and "Object.prototype") it will
drop out of the system and go freewack.
Theory: If a variable casted to an object returns true when strictly compared
to the original, the input must be an object.
Which is true. It doesn't change the inheritance, it doesn't make it inherit
from this window's Object if the object is from another window's object. All it
does is cast to an object if not an object already.
So e.g. "Object(5) !== 5" because 5 is a primitive value as opposed to an instance
of Number.
And contrary to "typeof", it doesn't return true for "null".
* .constructor also has the problem that it only works this way if the
input is a plain object. e.g. a simple construtor function that creates
an object also get in the wrong side of the if/else case since it is
an instance of Object, but not directly (rather indirectly via another
constructor).
* Added unit tests for basic getHash usage, as well as regression tests
against the above two mentioned problems (these tests fail before this commit).
* While at it, also improved other utilities a bit.
- Use hasOwnProperty instead of casting to boolean
when checking for presence of native support.
Thanks to Douglas Crockford for that tip.
- Fix documentation for ve.getHash: Parameter is not named "obj".
- Add Object-check to ve.getObjectKeys per ES5 Object.keys spec (to match native behavior)
- Add Object-check to ve.getObjectValues to match ve.getObjectKeys
- Improved performance of ve.getObjectKeys shim. Tried several potential optimizations
and compared with jsperf. Using a "static" reference to hasOwn improves performance
(by not having to look it up 4 scopes up and 3 property levels deep).
Also using [.length] instead of .push() shared off a few ms.
- Added unit tests for ve.getObjectValues

To do this, we are using the replacer callback of JSON.stringify, which is supported by all of our target browsers including IE8. We are also leaning on Object.keys and Array.reduce, the latter of which required adding a new fallback implementation for some browsers which do not support it yet.

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

Also:
* Removed a lot of dead code in Surface that was used in the now dead and gone sandbox.
* Changed from throwing an exception when calling getBalancedData on a range that produces no results from selectNodes to just returning []

This should make it much simpler to keep MediaWiki specifics out of VisualEditor, which will in turn make it easier to integrate VisualEditor into another platform.
Change-Id: I073e9737b37c28af889f2457d10b082cefd0d63b
This license change is aimed at maximizing the reusability of this code
in other projects. VisualEditor is more than just an awesome editor for
MediaWiki, it's the new editor for the entire internet.
Added license and author files, plus mentions of the license to all
VisualEditor PHP, JavaScript and CSS files. Parser files have not been
modified but are effectively re-licensed since there's no overriding
license information. 3rd party libraries are not changed, but are all
already MIT licensed.

* "onevar" warning sometimes solved by just merging var statements
other times solved by making it a function declaration instead
of a function expression.
* Also fixed several '_this' variable names in ve.es.Surface to
more descriptive names, and enabled warnings for dangling _
in identifiers.
Change-Id: I7d411881e3e06cf9a7fe56d689c29375881a81de
Fixed by adding the specialMessages module which is only loaded once the
editor loads. Then after it's loaded we use the summary message from
there to update the (possibly broken) summary message in the save
dialog.

* This high level surface object is responsible for creating & managing editor instances
* Revised Sandbox demo to invoke in this way.
