rememo(selector, getDependants) X-Ref

Returns a memoized selector function. The getDependants function argument is
called before the memoized selector and is expected to return an immutable
reference or array of references on which the selector depends for computing
its own return value. The memoize cache is preserved only as long as those
dependant references remain the same. If getDependants returns a different
reference(s), the cache is cleared and the selector value regenerated.

getCache(dependants) X-Ref

Returns the cache for a given dependants array. When possible, a WeakMap
will be used to create a unique cache for each set of dependants. This
is feasible due to the nature of WeakMap in allowing garbage collection
to occur on entries where the key object is no longer referenced. Since
WeakMap requires the key to be an object, this is only possible when the
dependant is object-like. The root cache is created as a hierarchy where
each top-level key is the first entry in a dependants set, the value a
WeakMap where each key is the next dependant, and so on. This continues
so long as the dependants are object-like. If no dependants are object-
like, then the cache is shared across all invocations.

return: {Cache} Cache object.
param: {*[]} dependants Selector dependants.

Resets root memoization cache.

callSelector() X-Ref

The augmented selector call, considering first whether dependants have

is not the block's registration settings, which must be retrieved from the
blocks module registration store.

getBlock recurses through its inner blocks until all its children blocks have
been retrieved. Note that getBlock will not return the child inner blocks of
an inner block controller. This is because an inner block controller syncs
itself with its own entity, and should therefore not be included with the
blocks of a different entity. For example, say you call `getBlocks( TP )` to
get the blocks of a template part. If another template part is a child of TP,
then the nested template part's child blocks will not be returned. This way,
the template block itself is considered part of the parent, but the children
are not.

Filters registered block settings, extending attributes to include `style` attribute.

return: {Object} Filtered block settings.
param: {Object} settings Original block settings.

omitStyle(style, paths, preserveReference = false) X-Ref

A utility function used to remove one or more paths from a style object.
Works in a way similar to Lodash's `omit()`. See unit tests and examples below.

It supports a single string path:

```
omitStyle( { color: 'red' }, 'color' ); // {}
```

or an array of paths:

```
omitStyle( { color: 'red', background: '#fff' }, [ 'color', 'background' ] ); // {}
```

It also allows you to specify paths at multiple levels in a string.

```
omitStyle( { typography: { textDecoration: 'underline' } }, 'typography.textDecoration' ); // {}
```

You can remove multiple paths at the same time:

```
omitStyle(
{
typography: {
textDecoration: 'underline',
textTransform: 'uppercase',
}
},
[
'typography.textDecoration',
'typography.textTransform',
]
);
// {}
```

You can also specify nested paths as arrays:

```
omitStyle(
{
typography: {
textDecoration: 'underline',
textTransform: 'uppercase',
}
},
[
[ 'typography', 'textDecoration' ],
[ 'typography', 'textTransform' ],
]
);
// {}
```

With regards to nesting of styles, infinite depth is supported:

```
omitStyle(
{
border: {
radius: {
topLeft: '10px',
topRight: '0.5rem',
}
}
},
[
[ 'border', 'radius', 'topRight' ],
]
);
// { border: { radius: { topLeft: '10px' } } }
```

The third argument, `preserveReference`, defines how to treat the input style object.
It is mostly necessary to properly handle mutation when recursively handling the style object.
Defaulting to `false`, this will always create a new object, avoiding to mutate `style`.
However, when recursing, we change that value to `true` in order to work with a single copy
of the original style object.

return: {Object}      Styles object with the specified paths removed.
param: {Object}       style             Styles object.
param: {Array|string} paths             Paths to remove.
param: {boolean}      preserveReference True to mutate the `style` object, false otherwise.

Hook used to compute the styles required to move a div into a new position.

The way this animation works is the following:
- It first renders the element as if there was no animation.
- It takes a snapshot of the position of the block to use it
as a destination point for the animation.
- It restores the element to the previous position using a CSS transform
- It uses the "resetAnimation" flag to reset the animation
from the beginning in order to animate to the new destination point.

should be the outermost element of a block. Call this hook and pass the
returned props to the element to mark as a block. If you define a ref for the
element, it is important to pass the ref to this hook, which the hook in turn
will pass to the component through the props it returns. Optionally, you can
also pass any other props through this hook, and they will be merged and
returned.

Use of this hook on the outermost element of a block is required if using API >= v2.

useBlockSync({clientId = null,value: controlledBlocks,selection: controlledSelection,onChange = use_block_sync_noop,onInput = use_block_sync_noop}) X-Ref

useBlockSync is a side effect which handles bidirectional sync between the
block-editor store and a controlling data source which provides blocks. This
is most commonly used by the BlockEditorProvider to synchronize the contents
of the block-editor store with the root entity, like a post.

Another example would be the template part block, which provides blocks from
a separate entity data source than a root entity. This hook syncs edits to
the template part in the block editor back to the entity and vice-versa.

Here are some of its basic functions:
- Initalizes the block-editor store for the given clientID to the blocks
given via props.
- Adds incoming changes (like undo) to the block-editor store.
- Adds outgoing changes (like editing content) to the controlling entity,
determining if a change should be considered persistent or not.
- Handles edge cases and race conditions which occur in those operations.
- Ignores changes which happen to other entities (like nested inner block
controllers.
- Passes selection state from the block-editor store to the controlling entity.

param: {Object}        props           Props for the block sync hook
param: {string}        props.clientId  The client ID of the inner block controller.
param: {Object[]}      props.value     The control value for the blocks. This value
param: {Object}        props.selection The selection state responsible to restore the selection on undo/redo.

Certain office-type programs, like Microsoft Word or Apple Numbers,
will, upon copy, generate a screenshot of the content being copied and
attach it to the clipboard alongside the actual rich text that the user
sought to copy. In those cases, we should let Gutenberg handle the rich text
content and not the screenshot, since this allows Gutenberg to insert
meaningful blocks, like paragraphs, lists or even tables.

normalizeWheel( event) X-Ref

Mouse wheel (and 2-finger trackpad) support on the web sucks.  It is
complicated, thus this doc is long and (hopefully) detailed enough to answer
your questions.

If you need to react to the mouse wheel in a predictable way, this code is
like your bestest friend. * hugs *

As of today, there are 4 DOM event types you can listen to:

'wheel'                -- Chrome(31+), FF(17+), IE(9+)
'mousewheel'           -- Chrome, IE(6+), Opera, Safari
'MozMousePixelScroll'  -- FF(3.5 only!) (2010-2013) -- don't bother!
'DOMMouseScroll'       -- FF(0.9.7+) since 2003

So what to do?  The is the best:

normalizeWheel.getEventType();

In your event callback, use this code to get sane interpretation of the
deltas.  This code will return an object with properties:

spinX   -- normalized spin speed (use for zoom) - x plane
spinY   -- " - y plane
pixelX  -- normalized distance (to pixels) - x plane
pixelY  -- " - y plane

Wheel values are provided by the browser assuming you are using the wheel to
scroll a web page by a number of lines or pixels (or pages).  Values can vary
significantly on different platforms and browsers, forgetting that you can
scroll at different speeds.  Some devices (like trackpads) emit more events
at smaller increments with fine granularity, and some emit massive jumps with
linear speed or acceleration.

This code does its best to normalize the deltas for you:

- spin is trying to normalize how far the wheel was spun (or trackpad
dragged).  This is super useful for zoom support where you want to
throw away the chunky scroll steps on the PC and make those equal to
the slow and smooth tiny steps on the Mac. Key data: This code tries to
resolve a single slow step on a wheel to 1.

- pixel is normalizing the desired scroll delta in pixel units.  You'll
get the crazy differences between browsers, but at least it'll be in
pixels!

- positive value indicates scrolling DOWN/RIGHT, negative UP/LEFT.  This
should translate to positive value zooming IN, negative zooming OUT.
This matches the newer 'wheel' event.

Why are there spinX, spinY (or pixels)?

- spinX is a 2-finger side drag on the trackpad, and a shift + wheel turn
with a mouse.  It results in side-scrolling in the browser by default.

- spinY is what you expect -- it's the classic axis of a mouse wheel.

- I dropped spinZ/pixelZ.  It is supported by the DOM 3 'wheel' event and
probably is by browsers in conjunction with fancy 3D controllers .. but
you know.

Implementation info:

Examples of 'wheel' event if you scroll slowly (down) by one step with an
average mouse:

OS X + Chrome  (mouse)     -    4   pixel delta  (wheelDelta -120)
OS X + Safari  (mouse)     -  N/A   pixel delta  (wheelDelta  -12)
OS X + Firefox (mouse)     -    0.1 line  delta  (wheelDelta  N/A)
Win8 + Chrome  (mouse)     -  100   pixel delta  (wheelDelta -120)
Win8 + Firefox (mouse)     -    3   line  delta  (wheelDelta -120)

On the trackpad:

OS X + Chrome  (trackpad)  -    2   pixel delta  (wheelDelta   -6)
OS X + Firefox (trackpad)  -    1   pixel delta  (wheelDelta  N/A)

On other/older browsers.. it's more complicated as there can be multiple and
also missing delta values.

The 'wheel' event is more standard:

http://www.w3.org/TR/DOM-Level-3-Events/#events-wheelevents

The basics is that it includes a unit, deltaMode (pixels, lines, pages), and
deltaX, deltaY and deltaZ.  Some browsers provide other values to maintain
backward compatibility with older events.  Those other values help us
better normalize spin speed.  Example of what the browsers provide:

| event.wheelDelta | event.detail
------------------+------------------+--------------
Safari v5/OS X  |       -120       |       0
Safari v5/Win7  |       -120       |       0
Chrome v17/OS X  |       -120       |       0
Chrome v17/Win7  |       -120       |       0
IE9/Win7  |       -120       |   undefined
Firefox v4/OS X  |     undefined    |       1
Firefox v4/Win7  |     undefined    |       3
