This PR fixes a bug where the drag distance for an interaction was being
measured in page space rather than screen space. It should be measured
in screen space. The actual check for `isDragging` is a little ugly but
this is correct.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `bugfix` — Bug fix
### Test Plan
1. Zoom in
2. Drag the center handle of an arrow shape
- [x] Unit Tests
### Release Notes
- Fixed a bug where the minimum distance for a drag was wrong when
zoomed in or out.
We have a lot of events that fire in the editor and, technically, they
can fire after the Editor is long gone.
This adds a registry/manager to track those timeout/interval/raf IDs
(and some eslint rules to enforce it).
Some other cleanups:
- `requestAnimationFrame.polyfill.ts` looks like it's unused now (it
used to be used in a prev. revision)
- @ds300 I could use your feedback on the `EffectScheduler` tweak. in
`useReactor` we do: `() => new EffectScheduler(name, reactFn, {
scheduleEffect: (cb) => requestAnimationFrame(cb) }),`
and that looks like it doesn't currently get disposed of properly.
thoughts? happy to do that separately from this PR if you think that's a
trickier thing.

Lots of people are having a bad time with loading/restoring snapshots
and there's a few reasons for that:
- It's not clear how to preserve UI state independently of document
state.
- Loading a snapshot wipes the instance state, which means we almost
always need to
- update the viewport page bounds
- refocus the editor
- preserver some other sneaky properties of the `instance` record

This PR identifies a bunch of places where the redo stack was being
blown when it shouldn't have been. I think this is going to be a
constant footgun unless we switch back to `ignore-by-default` behavior
for the store.
I also ignored changes to assets, which brings them back to how they
were being handled before the undo/redo change (i.e. they lived outside
of the undo/redo system).

This PR adds an (optional) options argument to the `Editor.groupShapes`
and `Editor.ungroupShapes` methods.
Taha's original PR:
This PR seeks to make it easier to disentangle shape selection logic
from the grouping shapes logic. This is one of two approaches we could
take to this problem.
Other PR is here: https://github.com/tldraw/tldraw/pull/3691
I think this is a better method because it doesn't require consumers of
the library with their own custom actions to change the way their own
grouping logic works. As evidenced by all the tests failing on the other
PR.

minor thing that was bugging me. we had a bunch of z-index vars that
were "unregistered". this brings them back into a consistent place so we
can see from a bird's eye view easily the stacking order of everything.
also, a drive-by fix to not duplicate `--tl-text-outline` inside of
`DefaultCanvas`

original bug was this:
https://github.com/tldraw/tldraw/assets/469604/1bb3c401-4221-4981-b4d9-7325ea27944c
it seemed to be related to how the Draw font specifically was kerning or
something (maybe ligatures??), we don't really know. it seems to be only
Chrome specific.
See video:
https://github.com/tldraw/tldraw/assets/469604/1a54ba78-ebd5-4ddf-9351-3ecc44a8702a
Also, there's a line height issue when resizing vertically:
https://github.com/tldraw/tldraw/assets/469604/b7b3ac16-70a6-476c-8f23-e619725799b6
So, to address these various things:
- for the overflow bug (and related Draw font issue), we do `Math.ceil`
to help with this fuzziness. I _think_ this will help but I'm not 100%
certain this will help in all cases.
- for the line height issue, we do `Math.floor` to avoid this subpixel
wonkiness
- for good measure, I made sure that the content & textarea rendering
has matching CSS styles (things like `font-feature-settings`, etc.) the
content now matches what the `textarea` has be default in Chrome's user
agent styling.
fuuuuuuun 🥳

You can now override many options which were previously hard-coded

the maximum number of pages, grid steps, or other previously hard-coded
values. See `TldrawOptions` for more
Before this PR, calling `setCamera` with an `animation` option would
calculate the target viewport based on the camera passed in without
first applying constraints. That meant that if the camera did indeed
need to be constrained you'd end up with some funky animations.

This PR reworks the `canBind` callback to work with customizable
bindings. It now accepts an object with a the shape, the other shape
(optional - it may not exist yet), the direction, and the type of the
binding. Devs can use this to create shapes that only participate in
certain binding types, can have bindings from but not to them, etc.
If you're implementing a binding, you can see if binding two shapes is
allowed using `editor.canBindShapes(fromShape, toShape, 'my binding
type')`
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `improvement` — Improving existing features
### Release Notes
#### Breaking changes
The `canBind` flag now accepts an options object instead of just the
shape in question. If you're relying on its arguments, you need to
change from `canBind(shape) {}` to `canBind({shape}) {}`.
Typescript's type aliases (`type X = thing`) can refer to basically
anything, which makes it hard to write an automatic document formatter
for them. Interfaces on the other hand are only object, so they play
much nicer with docs. Currently, object-flavoured type aliases don't
really get expanded at all on our docs site, which means we have a bunch
of docs content that's not shown on the site.
This diff introduces a lint rule that forces `interface X {foo: bar}`s
instead of `type X = {foo: bar}` where possible, as it results in a much
better documentation experience:

Previously, we were using touch and mouse events to detect when we were
in coarse/fine pointer mode. The problem with this is that many mobile
devices emulate mouse events for backwards compatibility with websites
not built for touch - so many touch events result in mouse events too.
The solution to this is to use the unified pointer events API, and check
the `pointerType` property to determine the device the user is using.

Our `InFrontOfTheCanvas` UI override component (we don't have a default
implementation, it's just an entry point for sdk users to insert their
own UI) was being mounted outside of the UI react context subtree, which
is an error because it won't have access to important things like
translations and asset URLs. #3750 made this bug manifest as a thrown
error in our `context-toolbar` example, as reported in #3773.
To fix this I just moved the injection site of the `InFrontOfTheCanvas`
component to be within the UI context. It ends up in the same place in
the DOM.
This PR closes#3773

Looking at #3762 it seemed to have been caused by calling
`setCurrentPage` during a `select.editing_shape` interaction. I wonder
whether we should trigger a `cancel` event before switching pages in
case this happens?

This revives the old 'derived camera' idea to prevent cursor wobbling
during viewport following.
Before this PR we updated the camera on a tick during viewport
following, but the shapes and cursors were not moving on the same tick
(we tried that during the perf work and it was all kinds of
problematic). Frankly I've forgotten how we ever managed to eliminate
wobble here in the first place?
Anyway after this PR we derive the camera based on whether or not we are
following a user. When you follow a user it makes it so that your
viewport contains their viewport. If your viewport is not already very
close to their viewport it will animate the initial position, after
which it will 'lock' in place and the derived value will be used from
then on.
This exposed a minor issue in our sync engine: the fact that we send
presence updates in separate websocket messages from document updates.
We get into situations like this
1. user A follows user B
2. user B deletes the current page they are on
3. user B's page deletion diff gets sent
4. user B's presence update gets sent with a new currentPageId
5. user A receives the page deletion
6. user A still thinks that user B is on the old page and doesn't know
how to update the follow state.
So to fix this I made it so that we can (and do) send presence updates
in the same websocket messages as document updates so the server can
handle them atomically.

Focus management is really scattered across the codebase. There's sort
of a battle between different code paths to make the focus the correct
desired state. It seemed to grow like a knot and once I started pulling
on one thread to see if it was still needed you could see underneath
that it was accounting for another thing underneath that perhaps wasn't
needed.
The impetus for this PR came but especially during the text label
rework, now that it's much more easy to jump around from textfield to
textfield. It became apparent that we were playing whack-a-mole trying
to preserve the right focus conditions (especially on iOS, ugh).
This tries to remove as many hacks as possible, and bring together in
place the focus logic (and in the darkness, bind them).
## Places affected
- [x] `useEditableText`: was able to remove a bunch of the focus logic
here. In addition, it doesn't look like we need to save the selection
range anymore.
- lingering footgun that needed to be fixed anyway: if there are two
labels in the same shape, because we were just checking `editingShapeId
=== id`, the two text labels would have just fought each other for
control
- [x] `useFocusEvents`: nixed and refactored — we listen to the store in
`FocusManager` and then take care of autoFocus there
- [x] `useSafariFocusOutFix`: nixed. not necessary anymore because we're
not trying to refocus when blurring in `useEditableText`. original PR
for reference: https://github.com/tldraw/brivate/pull/79
- [x] `defaultSideEffects`: moved logic to `FocusManager`
- [x] `PointingShape` focus for `startTranslating`, decided to leave
this alone actually.
- [x] `TldrawUIButton`: it doesn't look like this focus bug fix is
needed anymore, original PR for reference:
https://github.com/tldraw/tldraw/pull/2630
- [x] `useDocumentEvents`: left alone its manual focus after the Escape
key is hit
- [x] `FrameHeading`: double focus/select doesn't seem necessary anymore
- [x] `useCanvasEvents`: `onPointerDown` focus logic never happened b/c
in `Editor.ts` we `clearedMenus` on pointer down
- [x] `onTouchStart`: looks like `document.body.click()` is not
necessary anymore
## Future Changes
- [ ] a11y: work on having an accessebility focus ring
- [ ] Page visibility API:
(https://developer.mozilla.org/en-US/docs/Web/API/Page_Visibility_API)
events when tab is back in focus vs. background, different kind of focus
- [ ] Reexamine places we manually dispatch `pointer_down` events to see
if they're necessary.
- [ ] Minor: get rid of `useContainer` maybe? Is it really necessary to
have this hook? you can just do `useEditor` → `editor.getContainer()`,
feels superfluous.
## Methodology
Looked for places where we do:
- `body.click()`
- places we do `container.focus()`
- places we do `container.blur()`
- places we do `editor.updateInstanceState({ isFocused })`
- places we do `autofocus`
- searched for `document.activeElement`

### Release Notes
- Focus: rework and untangle existing focus management logic in the SDK
Before this PR the interface for doing cleanup when shapes/bindings were
deleted was quite footgunny and inexpressive.
We were abusing the shape beforeDelete callbacks to implement
copy+paste, which doesn't work in situations where cascading deletes are
required. This caused bugs in both our pin and sticker examples, where
copy+paste was broken. I noticed the same bug in my experiment with text
labels, and I think the fact that it took us a while to notice these
bugs indicates other users are gonna fall prey to the same bugs unless
we help them out.
One suggestion to fix this was to add `onAfterDelete(From|To)Shape`
callbacks. The cascading deletes could happen in those, while keeping
the 'commit changes' kinds of updates in the `before` callbacks and
theoretically that would fix the issues with copy+paste. However,
expecting people to figure this out on their own is asking a heckuva lot
IMO, and it's a heavy bit of nuance to try to convey in the docs. It's
hard enough to convey it here. Plus I could imagine for some users it
might easily even leave the store in an inconsistent state to allow a
bound shape to exist for any length of time after the shape it was bound
to was already deleted.
It also just makes an already large and muddy API surface area even
larger and muddier and if that can be avoided let's avoid it.
This PR clears things up by making it so that there's only one callback
for when a binding is removed. The callback is given a `reason` for why
it is being called
The `reason` is one of the following:
- The 'from' is being deleted
- The 'to' shape is being deleted
- The binding is being deleted on it's own.
Technically a binding might end up being deleted when both the `from`
and `to` shapes are being deleted, but it's very hard to know for
certain when that is happening, so I decided to just ignore it for now.
I think it would only matter for perf reasons, to avoid doing useless
work.
So this PR replaces the `onBeforeDelete`, `onAfterDelete`,
`onBeforeFromShapeDelete` and `onBeforeToShapeDelete` (and the
prospective `onAfterFromShapeDelete` and `onAfterToShapeDelete`) with
just two callbacks:
- `onBeforeUnbind({binding, reason})` - called before any shapes or the
binding have been deleted.
- `onAfterUnbind({binding, reason})` - called after the binding and any
shapes have been deleted.
This still allows all the same behaviour as before, without having to
spread the logic between multiple callbacks. It's also just clearer IMO
since you only get one callback invocation per unbinding rather than
potentially two. It also fixes our copy+paste footgun since we can now
implement that by just deleting the bindings rather than invoking the
`onBeforeDelete(From|To)Shape` callbacks.
I'm not worried about losing the explicit before/after delete callbacks
for the binding record or shape records because sdk users still have the
ability to detect all those situations with full nuance in obvious ways.
The one thing that would even require extra bookkeeping is getting
access to a shape record after the shape was deleted, but that's
probably not a thing anybody would want to do 🤷🏼

in many places, we use a pattern like `React.createContext({} as
Editor)` when defining contexts. This causes a problem: `{}` is not
`Editor`, but you can still `useEditor` wherever you like and your code
with run with this confusing non-editor value.
This diff updates all our `createContext` calls to default to `null`,
with an explicit check and error for missing values. Now, if you
`useEditor` outside of `<Tldraw />`, you'll get a message telling you
that it can only be used within `<Tldraw />`.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `improvement` — Improving existing features
### Release Notes
`useEditor` and other context-based hooks will now throw an error when
used out-of-context, instead of returning a fake value.
This adds a store-level "operation end" event which fires at the end of
atomic operations. It includes some other changes too:
- The `SideEffectManager` now lives in & is a property of the store as
`StoreSideEffects`. One benefit to this is that instead of overriding
methods on the store to register side effects (meaning the store can
only ever be used in one place) the store now calls directly into the
side effect manager, which is responsible for dealing with any other
callbacks
- The history manager's "batch complete" event is gone, in favour of
this new event. We were using the batch complete event for only one
thing, calling `onChildrenChange` - which meant it wasn't getting called
for undo/redo events, which aren't part of a batch. `onChildrenChange`
is now called after each atomic store operation affecting children.
I've also added a rough pin example which shows (kinda messily) how you
might use the operation complete handler to traverse a graph of bindings
and resolve constraints between them.

### Change Type

- [x] `chore` — other boring stuff
With the new work on bindings, we no longer need to keep any arrows
stuff hard-coded in `editor`, so let's move it to `tldraw` with the rest
of the shapes.
Couple other changes as part of this:
- We had two different types of `WeakMap` backed cache, but we now only
have one
- There's a new free-standing version of `createComputedCache` that
doesn't need access to the editor/store in order to create the cache.
instead, it returns a `{get(editor, id)}` object and instantiates the
cache on a per-editor basis for each call.
- Fixed a bug in `createSelectedComputedCache` where the selector
derivation would get re-created on every call to `get`
### Change Type

- [x] `improvement` — Improving existing features
### Release Notes
#### Breaking changes
- `editor.getArrowInfo(shape)` has been replaced with
`getArrowInfo(editor, shape)`
- `editor.getArrowsBoundTo(shape)` has been removed. Instead, use
`editor.getBindingsToShape(shape, 'arrow')` and follow the `fromId` of
each binding to the corresponding arrow shape
- These types have moved from `@tldraw/editor` to `tldraw`:
- `TLArcInfo`
- `TLArrowInfo`
- `TLArrowPoint`
- `WeakMapCache` has been removed
First draft of the new bindings API. We'll follow this up with some API
refinements, tests, documentation, and examples.
Bindings are a new record type for establishing relationships between
two shapes so they can update at the same time.
### Change Type
- [x] `sdk` — Changes the tldraw SDK
- [x] `feature` — New feature
### Release Notes
#### Breaking changes
- The `start` and `end` properties on `TLArrowShape` no longer have
`type: point | binding`. Instead, they're always a point, which may be
out of date if a binding exists. To check for & retrieve arrow bindings,
use `getArrowBindings(editor, shape)` instead.
- `getArrowTerminalsInArrowSpace` must be passed a `TLArrowBindings` as
a third argument: `getArrowTerminalsInArrowSpace(editor, shape,
getArrowBindings(editor, shape))`
- The following types have been renamed:
- `ShapeProps` -> `RecordProps`
- `ShapePropsType` -> `RecordPropsType`
- `TLShapePropsMigrations` -> `TLPropsMigrations`
- `SchemaShapeInfo` -> `SchemaPropsInfo`

This PR adds a slideshow example (similar to @TodePond's slides but more
on rails) as a way to put some pressure on camera controls.
Along the way, it fixes some issues I found with animations and the new
camera controls.
- forced changes will continue to force through animations
- animations no longer set unnecessary additional listeners
- animations end correctly
- updating camera options does not immediately update the camera (to
allow for animations, etc.)
It also changes the location of the "in front of the canvas" element so
that it is not hidden by the hit test blocking element.
### Change Type

This PR implements a camera options API.
- [x] Initial PR
- [x] Updated unit tests
- [x] Feedback / review
- [x] New unit tests
- [x] Update use-case examples
- [x] Ship?
## Public API
A user can provide camera options to the `Tldraw` component via the
`cameraOptions` prop. The prop is also available on the `TldrawEditor`
component and the constructor parameters of the `Editor` class.
```tsx
export default function CameraOptionsExample() {
return (
<div className="tldraw__editor">
<Tldraw cameraOptions={CAMERA_OPTIONS} />
</div>
)
}
```
At runtime, a user can:
- get the current camera options with `Editor.getCameraOptions`
- update the camera options with `Editor.setCameraOptions`
Setting the camera options automatically applies them to the current
camera.
```ts
editor.setCameraOptions({...editor.getCameraOptions(), isLocked: true })
```
A user can get the "camera fit zoom" via `editor.getCameraFitZoom()`.
# Interface
The camera options themselves can look a few different ways depending on
the `type` provided.
```tsx
export type TLCameraOptions = {
/** Whether the camera is locked. */
isLocked: boolean
/** The speed of a scroll wheel / trackpad pan. Default is 1. */
panSpeed: number

/** The steps that a user can zoom between with zoom in / zoom out. The first and last value will determine the min and max zoom. */
zoomSteps: number[]

This prevents duplicating shapes if we get to the max allowed shapes.
Before this change we would create as many shapes as we could and skip
the rest. After this change we don't create any shapes in this case.
We already do this for [copy
pasting](https://github.com/tldraw/tldraw/blob/mitja%2Fduplicate-shapes/packages/editor/src/lib/editor/Editor.ts#L7595-L7600)
(via `putContentOntoCurrentPage`), so no change was needed there.

This does more work for RTL rendering in SVG context, especially since
we position each span one-by-one.

solves our issue even though it isn't really recommend to be used by web

This PR fixes a bug where alt-dragging the left or right handles of a
text shape would not produce the correct outcome: the width would double
but the center would change.
This is because the text shape is aspect ratio locked only when dragging
handles other than the left or right, but we didn't have the ability to
differentiate between that. We've had to add that optionality in,
together with a hard-coded override of the normal behavior for text
shapes.

When a device has both a touch screen and a mouse, pointer: coarse
evaluates to false and then doesn't change even if the user begins to
use the touch screen.
In this PR pointer: coarse is replaced with any-pointer: coarse, which
checks if a touchscreen input is available. Event listeners for
touchstart and mousemove update isCoursePointer dynamically. So if the
user begins to move the mouse it changes to pointer: fine, if they then
touch the screen the pointer is returned to coarse.

Our undo-redo system before this diff is based on commands. A command
is:
- A function that produces some data required to perform and undo a
change
- A function that actually performs the change, based on the data
- Another function that undoes the change, based on the data
- Optionally, a function to _redo_ the change, although in practice we
never use this
Each command that gets run is added to the undo/redo stack unless it
says it shouldn't be.
This diff replaces this system of commands with a new one where all
changes to the store are automatically recorded in the undo/redo stack.
You can imagine the new history manager like a tape recorder - it
automatically records everything that happens to the store in a special
diff, unless you "pause" the recording and ask it not to. Undo and redo
rewind/fast-forward the tape to certain marks.
As the command concept is gone, the things that were commands are now
just functions that manipulate the store.
One other change here is that the store's after-phase callbacks (and the
after-phase side-effects as a result) are now batched up and called at
the end of certain key operations. For example, `applyDiff` would
previously call all the `afterCreate` callbacks before making any
removals from the diff. Now, it (and anything else that uses
`store.atomic(fn)` will defer firing any after callbacks until the end
of an operation. before callbacks are still called part-way through
operations.
## Design options
Automatic recording is a fairly large big semantic change, particularly
to the standalone `store.put`/`store.remove` etc. commands. We could
instead make not-recording the default, and make recording opt-in
instead. However, I think auto-record-by-default is the right choice for
a few reasons:
1. Switching to a recording-based vs command-based undo-redo model is
fundamentally a big semantic change. In the past, `store.put` etc. were
always ignored. Now, regardless of whether we choose record-by-default
or ignore-by-default, the behaviour of `store.put` is _context_
dependant.
2. Switching to ignore-by-default means that either our commands don't
record undo/redo history any more (unless wrapped in
`editor.history.record`, a far larger semantic change) or they have to
always-record/all accept a history options bag. If we choose
always-record, we can't use commands within `history.ignore` as they'll
start recording again. If we choose the history options bag, we have to
accept those options in 10s of methods - basically the entire `Editor`
api surface.
Overall, given that some breaking semantic change here is unavoidable, I
think that record-by-default hits the right balance of tradeoffs. I
think it's a better API going forward, whilst also not being too
disruptive as the APIs it affects are very "deep" ones that we don't
typically encourage people to use.

### Release Note
#### Breaking changes
##### 1. History Options
Previously, some (not all!) commands accepted a history options object
with `squashing`, `ephemeral`, and `preserveRedoStack` flags. Squashing
enabled/disabled a memory optimisation (storing individual commands vs
squashing them together). Ephemeral stopped a command from affecting the
undo/redo stack at all. Preserve redo stack stopped commands from wiping
the redo stack. These flags were never available consistently - some
commands had them and others didn't.
In this version, most of these flags have been removed. `squashing` is
gone entirely (everything squashes & does so much faster than before).
There were a couple of commands that had a special default - for
example, `updateInstanceState` used to default to being `ephemeral`.
Those maintain the defaults, but the options look a little different now
- `{ephemeral: true}` is now `{history: 'ignore'}` and
`{preserveRedoStack: true}` is now `{history:
'record-preserveRedoStack'}`.
If you were previously using these options in places where they've now
been removed, you can use wrap them with `editor.history.ignore(fn)` or
`editor.history.batch(fn, {history: 'record-preserveRedoStack'})`. For
example,
```ts
editor.nudgeShapes(..., { ephemeral: true })
```
can now be written as
```ts
editor.history.ignore(() => {
editor.nudgeShapes(...)
})
```
##### 2. Automatic recording
Previously, only commands (e.g. `editor.updateShapes` and things that
use it) were added to the undo/redo stack. Everything else (e.g.
`editor.store.put`) wasn't. Now, _everything_ that touches the store is
recorded in the undo/redo stack (unless it's part of
`mergeRemoteChanges`). You can use `editor.history.ignore(fn)` as above
if you want to make other changes to the store that aren't recorded -
this is short for `editor.history.batch(fn, {history: 'ignore'})`
When upgrading to this version of tldraw, you shouldn't need to change
anything unless you're using `store.put`, `store.remove`, or
`store.applyDiff` outside of `store.mergeRemoteChanges`. If you are, you
can preserve the functionality of those not being recorded by wrapping
them either in `mergeRemoteChanges` (if they're multiplayer-related) or
`history.ignore` as appropriate.
##### 3. Side effects
Before this diff, any changes in side-effects weren't captured by the
undo-redo stack. This was actually the motivation for this change in the
first place! But it's a pretty big change, and if you're using side
effects we recommend you double-check how they interact with undo/redo
before/after this change. To get the old behaviour back, wrap your side
effects in `editor.history.ignore`.
##### 4. Mark options
Previously, `editor.mark(id)` accepted two additional boolean
parameters: `onUndo` and `onRedo`. If these were set to false, then when
undoing or redoing we'd skip over that mark and keep going until we
found one with those values set to true. We've removed those options -
if you're using them, let us know and we'll figure out an alternative!
These were needed when the docs lived in a different repo, but they
don't any more so we can get rid of them.
### Change Type
- [x] `internal` — Does not affect user-facing stuff
- [x] `chore` — Updating dependencies, other boring stuff
