This PR fixes an extremely performance-crushing bug that was happening
in Safari and Chrome when iframes were present.
### Change Type
- [x] `patch` — Bug fix
### Test Plan
1. Create one hundred shapes
2. Create a gist or maps embed
3. Select all
If the app crashes or the rendering layers list grows to lots and lots
of layers, that's the bug.
### Release Notes
- [fix] iframe rendering issue
This PR fixes the effect of browser zoom on SVG overlays. I don't know
why this works.
Should fix https://github.com/tldraw/tldraw/issues/1834
### Change Type
- [x] `patch` — Bug fix
### Test Plan
1. Draw a rectangle.
2. Change your browser's zoom level (note: not tldraw's zoom level, just
your browser's).
3. Select the rectangle.
This PR fixes some creative use of CSS in setting the radius property of
various SVGs. While this use is supported in all browsers, it was
confusing CSS processors. Moving these out of CSS and into JavaScript
seems to be a pretty minor trade. Closes
https://github.com/tldraw/tldraw/issues/1775.
### Change Type
- [x] `patch` — Bug fix
### Test Plan
1. Ensure that borders and handles adjust their radii correctly when
zoomed in or out.
Previously, we'd used `Array.findLast` in `getSelectedShapeAtPoint`.
This PR removes that newish JS call and replaces it with a `replace` and
`find` instead. Closes bug mentioned in
https://github.com/tldraw/tldraw/issues/1798.

This PR updates the way that styles are changed. It splits `setStyle`
and `setOpacity` into `setStyleForNext Shape` and
`setOpacityForNextShape` and `setStyleForSelectedShapes` and
`setOpacityForSelectedShapes`. It fixes the issue with setting one style
re-setting other styles.
### Change Type

This PR improves the UX around sticky notes. It fixes were some bugs
related to the editing / hovered shape after cloning a sticky note
shape.
### Change Type
- [x] `patch` — Bug fix
### Test Plan
1. Use the sticky note tool
2. Alt-drag to clone sticky notes
3. Use the Enter key to edit the selected shape.
4. Double click an editable shape and then click once to edit a shape of
the same type.
- [x] Unit Tests
This PR includes further UX improvements to selection.
- clicking inside of a hollow shape will no longer select it on pointer
up
- clicking a shape's filled label will select it on pointer down
- clicking a shape's empty label will select it on pointer up
- clicking and dragging a selected arrow is now better limited to its
body, not its bounds
- arrows will no longer bind to labels
### Text labels
A big change here relates to text labels. Previously, we had listeners
set on the text label elements; I've removed these and we now check the
actual label bounds geometry for a hit. For geo shapes, this geometry is
now placed correctly based on the alignment / vertical alignment of the
label.
- Clicking on a label with text in it will select the shape on pointer
down.
- Clicking on an empty text label will select the shape on pointer up.
## Hollow shapes
Previously, shapes with `fill: none` were also being selected on pointer
up. I've removed that logic because it was producing wrong-feeling
selections too often. We now select these shapes only when clicking on
the label (as mentioned above) or when clicking on the edges of the
shape. This is in line with the original behavior (currently on
tldraw.com, prior to the earlier PR that updated selection logic).
## Arrows
Arrows still hit the inside of hollow shapes, using the "smallest
hovered" logic previously used for pointer-up selection on hollow
shapes. They also now correctly do so while ignoring text labels.
### Change Type
- [x] `minor` — New feature
### Test Plan
1. try selecting geo shapes, nested geo shapes, arrows and shapes with
labels or without labels
- [x] Unit Tests
This PR cleans up some APIs around the editor's current page state:

- `setCroppingShapeId` -> `setCroppingShape`
- `setFocusedGroupId` -> `setFocusedGroup`
- `setErasingShapeIds` -> `setErasingShapes`
- `setHintingShapeIds` -> `setHintingShapes`
It also adds some additional computed getters, e.g.
`Editor.croppingShape`.
It also adds some errors around `setCroppingShape`.
### Change Type

This PR:
- adds history options to several commands in order to allow them to
support squashing and ephemeral data (previously, these commands had
boolean values for squashing / ephemeral)
It also:
- changes `markId` to return the editor instance rather than the mark id
passed into the command
- removes `focus` and `blur` commands
- changes `createPage` parameters
- unifies `animateShape` / `animateShapes` options
### Change Type

- [x] Unit Tests
### Release Notes

This PR updates camera APIs:
- removes animateCamera
- adds animation support to setCamera
- makes camera commands accept points rather than an x/y
- `centerOnPoint`
- `pageToScreen`
- `screenToPoint`
- `pan`
- `setCamera`
- makes `zoomToBounds` accept a `Box2d` rather than x/y/w/h
- removes the `getBoundingClientRects` call from `getPointerInfo`
- removes the resize observer from `useScreenBounds`, uses an interval
instead when focused
A big (unexpected) improvement here is that `getBoundingClientRects` was
being called on every pointer move. This is a relatively expensive call
(it forces reflow) which could impact interactions. It's now called at
most once per second, and we could probably improve on that too if we
needed by only updating while in the select state.
### Change Type
- [x] `major` — Breaking change
### Test Plan
1. Try the multiple editors example after scrolling / resizing
2. Use the camera commands (zoom in, etc)

This PR removes the indexes from `parentsToChildrenWithIndexes`. The
indexes weren't needed except for in one place, where a `getShape` was
easier.
### Change Type
- [x] `minor` — New feature
This PR is a significant rewrite of our selection / hit testing logic.
It
- replaces our current geometric helpers (`getBounds`, `getOutline`,
`hitTestPoint`, and `hitTestLineSegment`) with a new geometry API
- moves our hit testing entirely to JS using geometry
- improves selection logic, especially around editing shapes, groups and
frames
- fixes many minor selection bugs (e.g. shapes behind frames)
- removes hit-testing DOM elements from ShapeFill etc.
- adds many new tests around selection
- adds new tests around selection
- makes several superficial changes to surface editor APIs
This PR is hard to evaluate. The `selection-omnibus` test suite is
intended to describe all of the selection behavior, however all existing
tests are also either here preserved and passing or (in a few cases
around editing shapes) are modified to reflect the new behavior.
## Geometry
All `ShapeUtils` implement `getGeometry`, which returns a single
geometry primitive (`Geometry2d`). For example:
```ts
class BoxyShapeUtil {
getGeometry(shape: BoxyShape) {
return new Rectangle2d({
width: shape.props.width,
height: shape.props.height,
isFilled: true,
margin: shape.props.strokeWidth
})
}
}
```
This geometric primitive is used for all bounds calculation, hit
testing, intersection with arrows, etc.
There are several geometric primitives that extend `Geometry2d`:
- `Arc2d`
- `Circle2d`
- `CubicBezier2d`
- `CubicSpline2d`
- `Edge2d`
- `Ellipse2d`
- `Group2d`
- `Polygon2d`
- `Rectangle2d`
- `Stadium2d`
For shapes that have more complicated geometric representations, such as
an arrow with a label, the `Group2d` can accept other primitives as its
children.
## Hit testing
Previously, we did all hit testing via events set on shapes and other
elements. In this PR, I've replaced those hit tests with our own
calculation for hit tests in JavaScript. This removed the need for many
DOM elements, such as hit test area borders and fills which only existed
to trigger pointer events.
## Selection
We now support selecting "hollow" shapes by clicking inside of them.
This involves a lot of new logic but it should work intuitively. See
`Editor.getShapeAtPoint` for the (thoroughly commented) implementation.
every sunset is actually the sun hiding in fear and respect of tldraw's
quality of interactions
This PR also fixes several bugs with scribble selection, in particular
around the shift key modifier.
...as well as issues with labels and editing.
There are **over 100 new tests** for selection covering groups, frames,
brushing, scribbling, hovering, and editing. I'll add a few more before
I feel comfortable merging this PR.
## Arrow binding
Using the same "hollow shape" logic as selection, arrow binding is
significantly improved.
a thousand wise men could not improve on this
## Moving focus between editing shapes
Previously, this was handled in the `editing_shapes` state. This is
moved to `useEditableText`, and should generally be considered an
advanced implementation detail on a shape-by-shape basis. This addresses
a bug that I'd never noticed before, but which can be reproduced by
selecting an shape—but not focusing its input—while editing a different
shape. Previously, the new shape became the editing shape but its input
did not focus.
In this PR, you can select a shape by clicking on its edge or body, or
select its input to transfer editing / focus.

This PR fixes snapping for arrow shapes. Previously, the middle handle
of an arrow was marked as a vertex, causing the arrow to have to
segments (one of which would be snapped to). In this PR we make the
second handle a "virtual" handle and tweak how we display handles to
preserve the same appearance.
### Change Type

This PR fixes a bug where dark mode would not immediately cause shapes
to update their colors. Previously, we got the current theme during
render but not in a way that hooked into the change. In this update, we
hook into the change. We also pass the change down to shape fills as
props rather than getting the theme from deeper down.
### Change Type

This PR removes several extraneous computed values from the editor. It
adds some silly instance state onto the instance state record and
unifies a few methods which were inconsistent. This is fit and finish
work 🧽
## Computed Values
In general, where once we had a getter and setter for `isBlahMode`,
which really masked either an `_isBlahMode` atom on the editor or
`instanceState.isBlahMode`, these are merged into `instanceState`; they
can be accessed / updated via `editor.instanceState` /
`editor.updateInstanceState`.

This PR moves code between our packages so that:
- @tldraw/editor is a “core” library with the engine and canvas but no
shapes, tools, or other things
- @tldraw/tldraw contains everything particular to the experience we’ve
built for tldraw
At first look, this might seem like a step away from customization and
configuration, however I believe it greatly increases the configuration
potential of the @tldraw/editor while also providing a more accurate
reflection of what configuration options actually exist for
@tldraw/tldraw.
## Library changes
@tldraw/editor re-exports its dependencies and @tldraw/tldraw re-exports
@tldraw/editor.
- users of @tldraw/editor WITHOUT @tldraw/tldraw should almost always
only import things from @tldraw/editor.
- users of @tldraw/tldraw should almost always only import things from
@tldraw/tldraw.
- @tldraw/polyfills is merged into @tldraw/editor
- @tldraw/indices is merged into @tldraw/editor
- @tldraw/primitives is merged mostly into @tldraw/editor, partially
into @tldraw/tldraw
- @tldraw/file-format is merged into @tldraw/tldraw
- @tldraw/ui is merged into @tldraw/tldraw
Many (many) utils and other code is moved from the editor to tldraw. For
example, embeds now are entirely an feature of @tldraw/tldraw. The only
big chunk of code left in core is related to arrow handling.
## API Changes
The editor can now be used without tldraw's assets. We load them in
@tldraw/tldraw instead, so feel free to use whatever fonts or images or
whatever that you like with the editor.
All tools and shapes (except for the `Group` shape) are moved to
@tldraw/tldraw. This includes the `select` tool.
You should use the editor with at least one tool, however, so you now
also need to send in an `initialState` prop to the Editor /
<TldrawEditor> component indicating which state the editor should begin
in.
The `components` prop now also accepts `SelectionForeground`.
The complex selection component that we use for tldraw is moved to
@tldraw/tldraw. The default component is quite basic but can easily be
replaced via the `components` prop. We pass down our tldraw-flavored
SelectionFg via `components`.
Likewise with the `Scribble` component: the `DefaultScribble` no longer
uses our freehand tech and is a simple path instead. We pass down the
tldraw-flavored scribble via `components`.
The `ExternalContentManager` (`Editor.externalContentManager`) is
removed and replaced with a mapping of types to handlers.
- Register new content handlers with
`Editor.registerExternalContentHandler`.
- Register new asset creation handlers (for files and URLs) with
`Editor.registerExternalAssetHandler`

### Release Notes
- Adds a cloud shape.
We'd like to make the @tldraw/editor layer more independent of specific
shapes. Unfortunately there are many places where shape types and
certain shape behavior is deeply embedded in the Editor. This PR begins
to refactor out dependencies between the editor library and shape utils.
It does this in two ways:
- removing shape utils from the arguments of `isShapeOfType`, replacing
with a generic
- removing shape utils from the arguments of `getShapeUtil`, replacing
with a generic
- moving custom arrow info cache out of the util and into the editor
class
- changing the a tool's `shapeType` to be a string instead of a shape
util
We're here trading type safety based on inferred types—"hey editor, give
me your instance of this shape util class"—for knowledge at the point of
call—"hey editor, give me a shape util class of this type; and trust me
it'll be an instance this shape util class". Likewise for shapes.
### A note on style
We haven't really established our conventions or style when it comes to
types, but I'm increasingly of the opinion that we should defer to the
point of call to narrow a type based on generics (keeping the types in
typescript land) rather than using arguments, which blur into JavaScript
land.

This PR removes the `tool` parameter from the `defineShape` function.
It's an opinionated change that I think we should at the very least
consider.
## What's the context?
Currently, you can add **tools** (aka state nodes) to your state chart
in two different ways:
1. Passing them to the `<Tldraw>` component with the `tools` attribute.
2. As part of a shape definition's `tool` property, which you then pass
to the `<Tldraw>` component with the `shapes` attribute.
This is what (1) looks like:
```jsx
import { MyTool } from "./MyTool"
function Example() {
return <Tldraw tools={[MyTool]} />
}
```
This is what (2) looks like:
```jsx
import { MyTool } from "./MyTool"
import { MyShapeUtil, myShapeProps } from "./MyShape"
const MyShapeDefinition = defineShape("my-shape", {
util: MyShapeUtil,
props: myShapeProps,
tool: MyTool,
})
function Example() {
return <Tldraw shapes={[MyShapeDefinition]} />
}
```
Clearly, (1) is better for when you want to add *just a tool*, that
doesn't have an associated shape.
And (2) is better for when you want to add *both* a tool and an
associated shape.
## Why change it?
I think we should remove method (2). Because I think that it adds a few
complications.
#### Does it help?
I don't think that it helps to streamline the process of coupling shapes
and tools. You still need to remember to add your tool.
Seeing as `tool` is optional on the shape definition (rightly so), it
doesn't prompt you to do it.
#### What's easier to explain?
I think it's easier to just have to explain _one method_. It would take
longer to explain two methods, and it complicates the concepts involved.
Seeing as there's not a big benefit to one method over the other, the
added explanation wouldn't be a good trade-off.
#### What happens if I use both?
It's unclear to the user what would happen if they use both methods. Do
we know what the intended behaviour of this would be? I think this will
happen often.
```jsx
import { MyTool } from "./MyTool"
import { MyShapeUtil, myShapeProps } from "./MyShape"
const MyShapeDefinition = defineShape("my-shape", {
util: MyShapeUtil,
props: myShapeProps,
tool: MyTool,
})
function Example() {
return <Tldraw tools={[MyTool]} shapes={[MyShapeDefinition]} />
}
```
#### Does it fit my shape/tool?
Many shapes are coupled closely with one tool. But some shapes would
involve multiple tools. And some tools would involve multiple shapes.
For example, you might first add a tool and a shape that go nicely
together, so you use method (2). But two months later, you decide that
you want another tool to be able to make this shape too. Now you've
inserted your related tools in two different places, unless you
refactor.
Alternatively, you might want to add some more functionality to your
tool, so that it can make multiple types of shapes. Instead of
refactoring the existing shape, you want to create an entirely new
shape, to keep your new code separate. Should you add the `tool`
property to the new shape as well? What would happen if you did/didn't?
What happens if you later disable the original shape? Would you need to
move the `tool` property from there to the newer shape?
It would be a lot simpler to just have the tool in your list of tools,
instead of having them tangled up with shapes.
#### Plugins?
We've been considering moving towards some sort of 'plugins' system in
the future, that could collect together shapes, tools, and other stuff.
I think that a more complete concept of a 'plugin' would be the best
place to collect together shapes, and tools — not on the shape itself.

This PR removes the strict state checks for the brush and zoom brush. We
should consider making the canvas more controlled by what exists (e.g.
whether a `brush` exists) rather than depending on particular statechart
states.
### Change Type

1. Create a brush manually in the API.
2. The brush should be visible on the canvas.
### Release Notes
- [editor] remove `editor.isIn` state checks for displaying brush and
zoom brush.
