This diff fixes a number of issues with text export by completely
overhauling how we approach laying out text in exports.
Currently, we try to carefully replicate in-browser behaviour around
line breaks and whitespace collapsing. We do this using an iterative
algorithm that forces the browser to perform a layout for each word, and
attempting to re-implement how the browser does things like whitespace
collapsing & finding line break opportunities. Lots of export issues
come from the fact that this is almost impossible to do well (short of
sending a complete text layout algorithm & full unicode lookup tables).
Luckily, the browser already has a complete text layout algorithm and
full unicode lookup tables! In the new approach, we ask the browser to
lay the text out once. Then, we use the
[`Range`](https://developer.mozilla.org/en-US/docs/Web/API/Range) API to
loop over every character in the rendered text and measure its position.
These character positions are then grouped into "spans". A span is a
contiguous range of either whitespace or non-whitespace characters,
uninterrupted by any browser-inserting line breaks. When we come to
render the SVG, each span gets its own `<tspan>` element, absolutely
positioned according to where it ended up in the user's browser.
This fixes a bunch of issues:
**Misaligned text due to whitespace collapsing at line breaks**
**Hyphenated text (or text with non-trivial/whitespace-based breaking
rules like Thai) not splitting correctly**
**Weird alignment issues in note shapes**
**Frame labels not respecting multiple spaces & not truncating
correctly**
#### Quick note on browser compatibility
This approach works well across all browsers, but in some cases actually
_increases_ x-browser variance. Consider these screenshots of the same
element (original above, export below):
Notice how on chrome, the whitespace at the end of each line of
right-aligned text is preserved. On safari, it's collapsed. The safari
option looks better - so our manual line-breaking/white-space-collapsing
algorithm preferred safari's approach. That meant that in-app, this
shape looks very slightly different from browser to browser. But out of
the app, the exports would have been the same (although also note that
hyphenation is broken). Now, because these shapes look different across
browsers, the exports now look different across browsers too. We're
relying on the host-browsers text layout algorithm, which means we'll
faithfully reproduce any quirks/inconsistencies of that algorithm. I
think this is an acceptable tradeoff.

This PR refactors our clipboard handlers. It should simplify the way
that things work and better handle the difference between how the native
API events are handled vs. the browser's clipboard API events.
Everything that used to be supported now also still works.
In addition, we now have several useful features:
### Multiline text can be pasted into the app
When pasting text that contains more than one line, the text is pasted
correctly; even if the clipboard also includes HTML data. Previously, we
would try to paste HTML data if we found it, because that data might
contain tldraw's own content as a comment; but if that failed, we would
paste the data as text instead. This led to pasting text that lost lots
of information from that text, such as line breaks and indentations.
### Multiline text shapes are aligned correctly
When pasting raw text that has more than one line, the text will be left
aligned—or right aligned if the text is likely from a RTL language.
### Common minimum indentation is removed from each line
This is something that absolutely every app should implement, but here
we go. When multiline text has "common indentation" on each line, which
is often the case when pasting text from code, then that indentation is
removed from each line.
### Auto wrapping for big pastes
When a line has no text breaks but a lot of text, we now set the width
of the text shape.
## How it works
A `ClipboardThing` is the common interface for things that we found on
the clipboard, native or otherwise. Both `handlePasteFromClipboardApi`
and `handlePasteFromEventClipboardData` parse out `ClipboardThing`s and
pass them to `handleClipboardThings`.
<img width="905" alt="image"
src="https://github.com/tldraw/tldraw/assets/23072548/fd087539-edbb-4527-b5ff-ca7d7c1726b2">
A `ClipboardResult` is the result of processing a `ClipboardThing`, and
usually contains text and other information about that text. We make
decisions on what to create based on which `ClipboardResult`s we find.
When pasting text, we check to see whether the result would be bigger
than the viewport, or if the text is multiline, or if the text is of an
RTL language by testing certain common RTL characters. We make some
adjustments based on those factors, ensuring that the top-left corner of
the text is on screen and reasonably positioned within the viewport if
possible.
### Change Type
- [x] `minor` — New Feature
### Test Plan
1. Copy and paste shapes
2. Copy and paste text from elsewhere into the app
3. Copy and paste images from elsewhere into the app
4. Try on different browsers
### Release Notes
- Improves clipboard logic when pasting text
- Adds support for pasting multi-line text
- Adds maximum widths when pasting single-line text
- Adds support for RTL languages when pasting multi-line or wrapped text
- Strips leading indentation when pasting text
We were storing the state of whether or not a document is read-only in

Expand the selection outline on draw shapes according to pen thickness
when only one shape is selected.
Right now the outline of many of our shapes don't take stroke thickness
into account. This is a pretty hard thing to get right, so in the short
term here's a fix for one of the most common places this is an issue:
selecting a single horizontal/vertical draw shape. This fix isn't
perfect: resizing gets slightly janky when you completely flip the shape
- see how the handle leaves the cursor behind in the gif when that
happens. We can revisit with a more comprehensive solution later.
This is pulled out from the highlighter work! The highlighter shape will
use the shape APIs added here.
### Change Type
- [x] `patch` — Bug Fix
### Test Plan
1. Create a draw shape
2. Select it
3. Selection bounds should include the stroke width
4. Add another shape to the selection
5. Selection bounds should no longer include the stroke width
### Release Notes
- Improve selection outlines around horizontal or vertical draw shapes
Allow the users to interact with embeds in readonly mode. Not sure if
this should apply to all embeds (cc @orangemug for thoughts on this)?
For example, you can also start editing code sandbox embeds.
One thing that doesn't feel quite right is that readonly mode defaults
to the hand tool, so you always have to switch to select tool to get
this working. I guess moving around is still the more common action
though so 🤷
### Test Plan
1. Create a multiplayer room with some embeds (youtube videos, spotify
playlist).
2. Open the room in readonly mode.
3. Make sure you can interact with embeds. Double click / enter when
selected, you should then be able to play the youtube videos.

We had a few issues with lazy race conditions failing CI. This came from
scripts configured to invoke lazy again, rather than through expressing
dependencies between scripts.
This diff reconfigures lazy to articulate these sorts of things as
dependencies instead of through self-invocation. Instead of having lots
of separate `build-package`, `build-docs`, etc commands, we now just
have a build command with package overrides to express more specific
options

This fixes a bug where creating a page would fail if there were multiple
pages with the same index.
This also changes the store to use a throttled version of
requestAnimationFrame. This should be good for relieving backpressure in
situations where the store is updated many times in quick succession. It
also makes testing a lot easier since it has the mocking logic built in.
### Change Type
- [x] `patch` — Bug Fix
### Release Notes
- Fix a bug where creating a page could throw an error in some
multiplayer contexts.
This PR updates tests for the text shape, as well as updating the logic
of `getTextLines`. We now:
- allow leading whitespace
- allow white space to cause line breaks, trim the whitespace off of the
end of the line. Crazy times!
- fix a bug with geo shapes changes width when growY changes
Note that this is not a "full solution" to line breaks that are caused
by whitespace + wrapping. AFAIK this is impossible to fix in SVG-land
without measuring the SVG element in order to collapse whitespace in the
same way that it collapses in HTML layout.

Our private tlsync package currently depends on the editor package,
which balloons the size of the cloudflare worker. It also makes it so
that any change to any package triggers a worker refresh, which makes
working on multiplayer stuff kinda miserable.
This is the first PR to fix that problem.
The second PR will need to resolve TLSyncClient's dependency on the
debugFlags somehow. Easiest would be to just remove the offending flag,
but we might want cross-bublic debug flags at some point in the future
so I'll try to find a low-cost way to make that happen while making
`tlsync` not depend on `editor`.
cc @TodePond since you added the flag in question

This PR adds a `check-box` geo shape.
It also improves some logic around the `onClick` shape util handler and

The <Canvas> component was previously split into an <SVGLayer> and an
<HTMLLayer>, mainly due to the complexity around translating SVGs.
However, this was done before we learned that SVGs can have overflow:
visible, so it turns out that we don't really need the SVGLayer at all.
This PR now refactors away SVG Layer.
It also updates the class name prefix in editor from `rs-` to `tl-` and
does a few other small changes.

This PR adds docs for the methods in the TLShapeUtil class.
I think that it's a good page to have docs on, as it shows people what's
possible with the custom shape API.
Currently, our docs are not showing `@param` info for lots of methods,
including the ones added in this PR.
I'll do fix for that in a follow-up PR, so that it's easier to review.
---
Note: Moving forward, we probably want to consider **_where_** these
docs are shown, and how we achieve that.
For example, do we put the docs for these methods in:
* The docs page for the `TLShapeUtil` class?
* The docs pages for the handler types, eg:
[`OnResizeHandler`](http://localhost:3000/gen/editor/OnResizeHandler-type)?
* Both?
Right now, I opted for putting them in the the TLShapeUtil class, as it
keeps them all in one place, and it's what we already do for some
others.
We should consider both - what works best for the docs? and what works
best for code editors?
---
This PR also includes a fix to our pre-commit step that @SomeHats did.
Right now this examples app looks exactly the same as our old examples
app, but there are a couple of tiny differences:
- We use `vite` instead of our own esbuild setup for development and
bundling
- We use `@tldraw/assets` for smart asset hashing instead of copying the
assets to a public folder
You can use `@tldraw/assets` with vite with a bunch of extra config, but
it (plus a bunch of other bundlers) also support a special syntax for
specifying asset urls: `new URL('./my/asset.svg',
import.meta.url).href`. This approach is more standards-complient, but
doesn't work with every bundler just yet. This diff also adds a
url-based version of `@tldraw/assets`, although I'd like to tweak the
entry point - right now you need to import from
`@tldraw/assets/lib/urls`, but i'd like to find a way to get this to
`@tldraw/assets/urls` or something at some point.
There are a couple other extra fixes in here:
- vscode builds were broken, they're fixed now!
- there's also a little tweak to the `getBundlerAssetUrls` API to allow
passing in a function instead of an object for URL formatting
- there are new internal-only functions for injecting asset urls
globally instead of passing them in via react props. this means we can
get the benefits of cacheable URLs without having to clutter our
examples by passing them in
In this PR I'm adding new versions of the `LiveCollaborators` and
`Collaborators` components for the ephemeral state work. They are behind
a feature flag for now.
This PR adds
- A new `TLInstancePresence` record type, to collect info about the
presence state in a particular instance of the editor. This will
eventually be used to sync presence data instead of sending
instance-only state across the wire.
- **Record Scopes**
`RecordType` now has a `scope` property which can be one of three
things:
- `document`: the record belongs to the document and should be synced
and persisted freely. Currently: `TLDocument`, `TLPage`, `TLShape`, and
`TLAsset`
- `instance`: the record belongs to a single instance of the store and
should not be synced at all. It should not be persisted directly in most
cases, but rather compiled into a kind of 'instance configuration' to
store alongside the local document data so that when reopening the
associated document it can remember some of the previous instance state.
Currently: `TLInstance`, `TLInstancePageState`, `TLCamera`, `TLUser`,
`TLUserDocument`, `TLUserPresence`
- `presence`: the record belongs to a single instance of the store and
should not be persisted, but may be synced using the special presence
sync protocol. Currently just `TLInstancePresence`
This sets us up for the following changes, which are gonna be pretty
high-impact in terms of integrating tldraw into existing systems:
- Removing `instanceId` as a config option. Each instance gets a
randomly generated ID.
- We'd replace it with an `instanceConfig` option that has stuff like
selectedIds, camera positions, and so on. Then it's up to library users
to get and reinstate the instance config at persistence boundaries.
- Removing `userId` as config option, and removing the `TLUser` type
altogether.
- We might need to revisit when doing auth-enabled features like locking
shapes, but I suspect that will be separate.
