Ed Sanders 8b09dd7650 The resurrection
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)

Trevor Parscal 2419f7638c Death and/or destruction
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.

Ed Sanders fdf30b1ac8 Store data in LinearData class with an index-value store for objects
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.

Ed Sanders 9a7b8aacf8 Only unwrap { generated: wrapper } based on context.
Wrapper paragraphs should only be unwrapped if they are the first
element in their parent - or if there is a block level element separating
them from the previous unwrapped paragraph.

Empty paragraphs should only be unwrapped if they are empty and the
last element in their parent.

Also in this commit is a simple test for IndentationAction.decrease().

Trevor Parscal 8d33a3de0d Major Documentation Cleanup
* Made method descriptions imperative: "Do this" rather than "Does this"
* Changed use of "this object" to "the object" in method documentation
* Added missing documentation
* Fixed incorrect documentation
* Fixed incorrect debug method names (as in those VeDmClassName tags we add to functions so they make sense when dumped into in the console)
* Normalized use of package names throughout
* Normalized class descriptions
* Removed incorrect @abstract tags
* Added missing @method tags
* Lots of other minor cleanup

Timo Tijhof b11bbed7a6 JSDuck: Generated code documentation!
See CODING.md for how to run it.

Mistakes fixed:
* Warning: Unknown type function
  -> Function
* Warning: Unknown type DOMElement
  -> HTMLElement
* Warning: Unknown type DOM Node
  -> HTMLElement
* Warning: Unknown type Integer
  -> Mixed
* Warning: Unknown type Command
  -> ve.Command
* Warning: Unknown type any
  -> number
* Warning: Unknown type ve.Transaction
  -> ve.dm.Transaction
* Warning: Unknown type ve.dm.AnnotationSet
  -> ve.AnnotationSet
* Warning: Unknown type false
  -> boolean
* Warning: Unknown type ve.dm.AlienNode
  ve.dm doesn't have a generic AlienNode like ve.ce
  -> Unknown type ve.dm.AlienInlineNode|ve.dm.AlienBlockNode
* Warning: Unknown type ve.ve.Surface
  -> ve.ce.Surface
* ve.example.lookupNode:
  -> Last @param should be @return
* ve.dm.Transaction.prototype.pushReplace:
  -> @param {Array] should be @param {Array}
* Warning: ve.BranchNode.js:27: {@link ve.Node#hasChildren} links to non-existing member
  -> (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.

Trevor Parscal b04a920616 (bug 41929) Unlist button overzealously unlists the whole list
ve.IndentationAction
* Fix incompatibility with working with multiple nodes by using surface fragments
* Bug was caused by unindent causing rebuilding, which for all groups other than the first meant their nodes were detached and broken

ve.ListAction
* Employ unindent in a loop to remove all list levels

This is all still a bit hacked together, the use of surface fragments saved us this time, but we need to refactor this code. Badly. Next year.

Trevor Parscal 735ed96f5f Add ve.Action, ve.ActionFactory, subclasses
Moved implementation of all the tools into a reusable action
system. To execute an action just call

surface.execute( actionName, method, param1, param2, ... );

This helps keep tools simple, and opens the door to key commands
reusing the same code.
