### Change Type
- [x] `patch` — Bug fix
Reverts tldraw/tldraw#1778.
Fuzz testing picked up errors related to deleting pages and undo/redo
which may doom this PR.
### Change Type
- [x] `major` — Breaking change
This PR shrinks the commands API surface and adds a manager
(`CleanupManager`) for side effects.
### Change Type
- [x] `major` — Breaking change
### Test Plan
Use the app! Especially undo and redo. Our tests are passing but I've
found more cases where our coverage fails to catch issues.
### Release Notes
- tbd
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.
tldraw, glorious tldraw

- [ ] End to end tests // todo
### Release Notes
- [editor] Remove `ShapeUtil.getBounds`, `ShapeUtil.getOutline`,
`ShapeUtil.hitTestPoint`, `ShapeUtil.hitTestLineSegment`
- [editor] Add `ShapeUtil.getGeometry`
- [editor] Add `Editor.getShapeGeometry`
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`
