* feat: author behaviours on main components
A main component or component set can behave as a Switch, Checkbox,
Slider, or Tabs, after Reka UI's primitives. The behaviour lives in
OpenPencil plugin data: boolean values bind to variant or boolean
properties with the values meaning on and off, a number keeps its own
range since Figma has no number property, and the control's
subcomponents bind to the component's slots. A Behaviour section in the
properties panel adds, binds, and removes it, each as one undo step,
and flags required bindings that are missing. The canvas-only layout's
pill becomes a component that preview will reuse.
* feat: preview instances with behaviours on the canvas
View > Preview (Cmd+Alt+Enter) puts the canvas in preview: a lone canvas
switches to the canvas-only layout with a Previewing pill, and a split
canvas previews on its own side. Clicking a Switch or Checkbox flips it,
dragging a Slider moves its thumb and range, and clicking a Tabs trigger
shows its panel. Preview keeps its state on copies of the instances it
touched, in a private graph with the document's ids, and the canvas
draws those copies in place of the originals, so the document, undo,
autosave, and collaborators never see it. Escape or the pill leaves
preview, Reset restores every control, and editing shortcuts, labels,
and outlines stay off while previewing.
* feat: translate behaviour and preview strings; cover preview with an e2e flow
* refactor(vue): reuse VariantDefinitionControl for behaviour property options
* refactor: split variant actions and preview interactions by domain
Variant authoring was one 706-line closure; it is now graph queries
(model), undo snapshots (history), property definition edits
(definitions), and the editor facade (index). Preview interactions move
into play/kinds, one module per control, registered by behaviour kind so
a new kind cannot ship without its contract and interaction. Behaviour
contracts are keyed by kind. In the Vue SDK, slot and variant authoring
controls get their own folders beside component-props and behaviour,
and the app's variant section joins slot/ and behaviour/.
* refactor: keep the behaviour model in scene-graph's plugin-data registry
Master now defines every OpenPencil plugin-data key in one typed registry
in scene-graph. The behaviour schema registers there as a field, and the
model and contracts move beside slots, exported from the package root;
the @open-pencil/core/behaviours subpath is gone.
* feat: interaction states and keyboard focus in preview
A behaviour can bind a variant property to the default, hover, pressed,
focus, and disabled states; binding it maps values named like those
states. Preview switches the instance's copy to the matching variant as
the pointer hovers, presses, and releases, keeps other values when the
set draws the combination and falls back to rest otherwise, and skips
disabled instances. Tab moves visible keyboard focus between controls,
Space, Enter, arrows, Home, and End use the focused one, and Escape
takes visible focus off before leaving preview. A Button kind covers
controls that only have states.
* feat: toggle, radio, group, progress, collapsible, and accordion behaviours
Radio group, toggle group, and accordion hold their items in a slot;
each item is an instance with its own behaviour, so a press inside the
slot goes to the group, which turns the pressed item on and the others
off through the item's own interaction. Progress shares the slider's
number handling through rangeControl, and a collapsible shows and hides
its content slot from its trigger, remembering its open state even
when no property draws it. Tabs and groups share arrow-key navigation.
* feat: text field, textarea, and number field behaviours
A behaviour value can now be text, bound to a text property, so
preview types into a copy of the field through the same property path
the editor uses. A bound Filled value switches to the placeholder
variant when the field empties. A number field keeps its own range,
shows its value through a text property, and steps from its increment
and decrement slots and the arrow keys. Text fields show focus from a
click, and the focused control receives every key; Option still types,
and only Cmd or Ctrl combinations stay shortcuts.
* fix: keep behaviour bindings when saving as .fig
Saving as .fig gives component properties new GUIDs, but behaviours
kept the old ids in their plugin data, so every binding read as missing
after reopening. The export now renames the ids behaviours bind with
the same GUIDs, on its own copy of the document.
* fix: let previewed controls resize layout imported from .fig
Layers from a .fig keep the sizes Figma computed, and auto layout
prefers them, so an opened collapsible or accordion item kept its
closed height in preview. When preview shows, hides, or retypes a
layer in a copy, it drops those sizes from the layer's copied ancestors
so auto layout sizes them again; untouched layers keep Figma's sizes.
* fix: publish behaviours and other plugin content with library assets
Every OpenPencil plugin-data field now declares its role: content that
exists only as plugin data (behaviours, OkHCL picks), format copies of
node fields written for files, or bookkeeping about where a document
or node came from. Library snapshots keep a node's content plugin data,
including other plugins' entries, and drop the rest; the asset hash
counts the same entries, so a behaviour-only change is offered as an
update while a .fig round trip still changes nothing.
* feat: name behaviour rows by meaning and create what they need
The Behaviour section named every main value "Value" under a "Values"
heading, and a component without matching properties left an empty
picker with no way forward. Rows are now named for the control (On,
Checked, Pressed, Text), rows the control needs or already uses come
first, and the optional rest folds under More options; a button keeps
its states in view. An empty row creates what it needs in one undo
step: a text layer and text property, Off and On variants on a set, or
a slot frame for a part. The missing chip names the row it means and
takes you there.
* fix(dom-css): position free layers, hug content, and round ellipses
HTML and Tailwind export stacked the layers of frames without auto
layout in block flow, wrote fixed pixel sizes for auto layout frames
set to Hug and for auto-sizing text, and drew ellipses as boxes. Layers
a parent does not lay out are now absolutely positioned at their
coordinates inside a relative frame, hugging axes are left to the
content, and ellipses get a 50% radius.
* feat: run preview as live Reka UI islands over the canvas
Preview simulated controls on the canvas: copies of instances, a
handler per kind, its own key routing, and append-only text. It now
runs them as real components. Each top-level layer that holds an
instance with a behaviour becomes an island: its layers are projected
to DOM through dom-css into a shadow root laid over the pane at its pan
and zoom, and each behaviour mounts its Reka UI primitives on its
layers, so text fields are real inputs and focus, keys, and layout are
the browser's. Core's resolvePlayState shows instances in a state on a
private graph, so the component's variants draw it, and controls are
keyed by layer path so a variant switch keeps their DOM. The canvas
leaves island layers to the islands, and the canvas play runtime and
its key routing are gone.
* fix: derive variant properties from Property=Value component names
figma.combineAsVariants and Combine as variants only derived variant
properties from slash-separated names, so components named as Figma
names variants, such as State=On, Size=Large, became a set with no
properties. Both now derive each named property and its values, after
the slash form.
* feat: script and tool access to behaviours by name
Behaviour contracts follow Reka UI's anatomy: tabs keep their triggers
in the list slot and their content panels in a panels slot, and a slot
of repeated parts names the Reka part of its children. A behaviour
spec names component properties and slots instead of ids and resolves
to the stored behaviour and back, with errors that list what the
component has.
Scripts get an `openpencil` global next to `figma`, in the Figma API's
style: setBehaviour, getBehaviour with bindValue, bindPart, states,
and missing, behaviourKinds, and createSlot. The eval tool, the CLI,
and app automation compile scripts through one compileScript, so the
CLI now returns the last expression as the others do. MCP and AI chat
get set_behaviour, get_behaviour, and create_slot.
* feat: write controls in design JSX with Reka UI's element names
`<Switch.Root modelValue="State">` renders a main component, or a set
when its children are variants, that behaves as a switch, and
`<Switch.Thumb>` the slot that draws its thumb, one slot across the
set's variants. Inputs become the text property of a field, tab
triggers and panels go in their List and Panels slots, and a group's
items are `<RadioGroup.Item of={…} />` instances in its Items slot.
JSX export writes components with behaviours the same way, so they
render back unchanged. The authoring reference documents controls, and
the codegen and chat prompts now include it verbatim instead of
dedenting its code examples.
* chore: format the CLI export test
* docs: document slots, behaviours, preview, and the openpencil API
The components guide covers slots, behaviours, and preview with its
shortcut; scripting covers the openpencil global and eval's last-
expression result; the MCP and AI chat pages list the new tools; the
features overview, README, and roadmap mention working controls. The
chat prompt says how to build a control, and the codegen prompt builds
components with behaviours on their Reka UI primitives.
* chore: format the eval CLI test
* docs: explain behaviours and preview islands, and guide the openpencil API
A development page explains the behaviour model, the four authoring
surfaces, how preview islands turn a control's state into live Reka UI
components, and how to add a kind; the architecture page links it. The
Core guide sets the rules for OpenPencilAPI: Figma-only `figma`,
OpenPencil features on `openpencil` in the same style, one
compileScript, names over ids, and docs with every member. Package
READMEs mention the openpencil global, PlayIslands, Reka-named JSX, and
the behaviour model. Design JSX's behaviour modules move into a
behaviours folder instead of a suffixed sibling.
* refactor: center pasted layers through translate
centerNodesAt repeated translate's loop, which test:dupes reports on
master too.
* fix: validate behaviour ranges and guess on and off by name
A number value now needs max above min and a positive step: the schema,
specs, and the panel reject a range a slider cannot step through. Binding
a variant property guesses on and off by value name, as specs do, and a
boolean property gets no on/off pair. Part bindings are read through
partBinding, a replaced document restarts preview from its designed
state, and the e2e preview shortcut uses ControlOrMeta.
* feat: make the Behaviour section say what to do next
A slider's range fields now carry inline Min, Max, Step, and Start labels.
States offers Add state variants, which adds a Default, Hover, Pressed,
Focus, and Disabled variant and binds them; Add Off and On variants and
Add state variants turn a lone main component into a component set first,
and a part's slot can be added to a set, in every variant under one slot
id. Rows that could do nothing are gone: no empty pickers and no hints to
combine variants by hand, and an unbound Disabled is left to the states.
A warning line names what is still needed and replaces the missing chip,
and the Switch's main value is called Checked.
* fix: keep each slot to one part and keep creating slots at hand
A slot draws one part, so the Behaviour section no longer offers a slot
another part uses, and specs (the openpencil API, tools, and JSX) reject
binding one slot to two parts. A part's picker keeps an action to add a
new slot in its footer, so adding the first slot no longer hides it for
the other parts.
* feat: let a collection name the attribute its modes switch by
Manually switched modes were always selected by data-<collection name>, so a collection called New wrote data-new and a codebase already using data-color-scheme could not be matched. A collection can now name its attribute in the inspector, validated so a stylesheet can select it as is. The stylesheet and exported code use it, setting it is undoable, and .fig files keep it in the collection's plugin data.
* fix: show the switch attribute only where there are modes to switch
* fix: return to the list after committing the switch attribute
* fix: keep a collection's switch attribute when a new one is refused
setModeAttribute cleared the attribute when given a name a stylesheet cannot select on; it now leaves the current one, and only an empty name restores the default. In the inspector, Enter on a refused name keeps the focus so it can be corrected.
* docs: describe the switch attribute in the mode conditions
The Switched manually row still said the attribute is named after the collection. The changelog had collected four copies of the variables dialog entry through rebases; one remains, with the switch attribute in it.
* feat: prototype the design tokens panel
Undoable editor actions for token fields and mode conditions, a token view model, and table, inspector, collection and stylesheet panels shown in a Storybook story with a real editor.
* feat: lay the tokens panel out for mobile
Below the mobile breakpoint the collection tabs become a select, the list shows one chosen mode with the CSS name under each token, and the token, the modes, and the stylesheet each open over the list behind Back. CodeViewer can fill its container for the full-screen stylesheet.
* feat: share drill-in navigation and put tokens on a listbox
PanelDrillIn gives detail views one back control that names where it returns, a slide preset from theme/motion, and focus that moves into the detail and back to what opened it. The Settings model editor and the tokens panel's mobile views use it. The token list is a Reka Listbox with arrow-key navigation and labelled groups, and the inspector and stylesheet swap with a short fade under the motion policy.
* feat: lay the tokens panel out by container width
The panel switches to the compact drill-in by its own measured width, and the list's columns follow the list's width through container queries, so the panel adapts inside dialogs and split views, not only on phones. src/AGENTS.md now says when to use container queries, measured size, and viewport breakpoints.
* test(core): group the variable undo tests in a domain folder
* feat: edit variables as tokens in the variables dialog
The variables dialog now hosts the tokens panel: a grouped token list with CSS names, an inspector for each token and for the collection and its modes, and the live stylesheet. It keeps adding variables by type, search, collection and mode management, and copying the document's stylesheet, and lays out by its own width down to phones.
useVariables().collections returns copies, so components given a collection see modes added or renamed in place, and addVariable returns the new ID so the panel can open it.
* fix: satisfy the type-aware lint in token updates and panel stories
* docs: describe the tokens panel in the translated variables guides
* feat: say when each mode applies in plain words
A mode's condition was a raw CSS field that designers could not read. Each non-default mode now picks when it applies (switched manually, system dark or light mode, high contrast, reduced motion, screen or container width, or custom CSS), with the CSS it writes shown underneath and a note on how the mode behaves on the canvas and in exported code. Presets only write the condition string modes already store, so files round-trip unchanged. Column headers name the condition in words, and deleting the collection moves into a menu beside its name.
* feat: bring the variables dialog up to Figma's
The dialog now covers what Figma's variables dialog offers: collections and groups in a sidebar with counts, a group, search and type filter, type icons, names and values edited in place, drag to reorder, multi-select with a context menu, the Delete key and a side panel to duplicate, group and delete, aliases chosen from a variable picker and detached back to the value they showed, hiding from publishing, and an expand toggle. It opens from View → Variables… and the command palette as well as the Design panel.
It also fixes review findings: a single-mode collection labels its value Value, column titles share one font, a CSS name is typed after a fixed -- and checked by the CSS parser before it is saved, and the stylesheet previews CSS with the format chosen when copying. AppInput applies an instance's input classes last so they can override adornment padding.
* feat: undo and redo inside the variables dialog
Canvas shortcuts stop while any dialog is open, so Cmd+Z did nothing in the variables dialog although every edit there is on the editor's history. Undo and redo now take a document scope: they also run when the topmost layer is a dialog that edits the document, which the variables dialog marks, while menus, pickers and Settings still hold them back and a field with uncommitted text keeps its own undo.
Enter commits a field and returns focus to the list. The panel drops selections, group filters and collections that undo removed. A color picker session undoes as one step through a coalesce key on updateVariableValue, and undoing a deletion puts the variable back in its place.
* feat: search variables like the command palette
The variables search matched a substring of the name only, so a CSS name, a hex color or a description found nothing, and the palette, AppPicker and AppCombobox each spelled out the same Fuse.js options. One helper in @open-pencil/vue now owns the matching: fuzzySearch ranks results for lists people pick from, and fuzzyFilter keeps a list's own order for lists people arrange. The panel searches names, CSS names, descriptions and every mode's value, alias names included; useVariables() searches names and descriptions.
* fix: say a token group once when its name repeats it
Kits that mirror Tailwind classes name tokens like Gap/gap-1, which derived --gap-gap-1. A group the next segment repeats is now said once, giving --gap-1.
* fix: keep the add variable menu under its button after a resize
The toolbar swaps the icon button for the labelled one when the dialog widens. Reka keeps the anchor it mounted with, so the menu opened at the window corner; keying the trigger remounts it with the new button.
* fix: leave bound layers alone when variables are added or reordered
Adding, copying, or reordering variables re-resolved every bound layer in the document. In the shadcn kit two Avatar instances are saved at 24 while their binding gives 40, so adding a number resized them and relaid out about 7,800 layers, freezing the browser for seconds. These changes alter no bound value and now only request a render, as renaming already did.
* refactor: let the variables dialog own its undo shortcuts
Undo and redo in the dialog went through a document scope in the global shortcut registry, which decided whether the dialog was on top by querying Reka's dismissable layers in DOM order. The dialog now listens on its own content with a tinykeys handler built from the command keybindings: menus and pickers it opens portal elsewhere, so their keys never reach it, and the registry is back to one scope.
* refactor: read mode conditions with css-tree
Presets were recognized by normalizing the condition with regular expressions and matching another. css-tree, which Core already ships through unifont, now parses the condition into its media or container feature, so spacing, case and comments are handled as CSS does, and a non-breaking space, which CSS does not treat as whitespace, no longer turns a custom condition into a preset.
* refactor: take the mode attribute hint from modeAttribute
The hint for a manually switched mode cut the brackets off its selector with a regular expression. It now reads the attribute name and value from modeAttribute, which the selector is built from.
* fix: keep a refused CSS name in focus and color picker sessions apart
Enter on a CSS name the parser refuses no longer hands the keyboard back to the list, so the name can be corrected. The typed name is read with parseCSSName instead of stripping a leading -- by hand, so a pasted var(--name) works too.
Each color picker session takes a random undo key; a counter restarted when the inspector remounted, so two sessions on the same token could merge into one undo step.
* fix: keep token expressions and cleared fields in step with their variable
Editing a number left its CSS expression recording the old number, so reopening the file dropped the expression as edited elsewhere. A number now updates its expression, and an alias drops it, in the same undo step.
Undoing a token field that had been unset kept the key with an undefined value; it is now removed.
* fix: preview and detach aliases in their own mode
An alias in the Dark column showed, and detached to, what its target gives in the mode the canvas is in. Both now resolve in the column's mode.
* fix: drop tokens a filter hides from the selection
A search, group, or type filter could hide selected tokens that stayed selected, so the inspector, the bulk actions, and the Delete key still acted on rows the list no longer showed.
* fix: keep a drill-in's list out of the tab order while its detail slides
The list stayed focusable until the detail finished sliding in, and became focusable again under a detail sliding out. It is now inert from the moment the detail opens and the departing detail is inert. A detail with no field focuses its back control, and hidden inputs are skipped.
* docs: drop a duplicated Stroke entry from the changelog
Two merges left the Stroke-extends-Fill breaking change twice; the copy that still said strokes render solid only is outdated, since gradient and image strokes now import and render.
* fix(core): start new layers with Figma's defaults in the editor and plugin API
The plugin API created bare nodes: frames, components, and shapes without fills, and lines and vectors without strokes, so scripts written for Figma drew nothing. Drawn lines also had a black fill instead of a stroke and were invisible. Both paths now share newLayerDefaults, recorded from Figma desktop 126: frames and components white with frames clipping their content, shapes #D9D9D9, lines and vectors a black 1 px stroke, text black. A stroke a script adds gets the 1 px default weight, and an empty vector has no render bounds.
* fix(core): combine variants as Figma does from the canvas and from scripts
The plugin API and the editor command each built component sets their own way, both with 40 px of padding and a grey fill. Figma's command pads the variants by 20 and outlines the set with a 1 px dashed #8A38F5 stroke; its plugin API wraps them exactly with no fill or stroke. One variantSetProps now places and styles the set for both, with a canvas or script style, and applyVariantProperties derives variant properties for both.
* fix(core): report group children in their container's space in the plugin API
Figma's plugin API places children of groups and booleans relative to the nearest real container and refits a group whenever a script changes one of its children. Ours reported group-relative positions and never refit, so scripts placing layers inside groups landed them in the wrong place. x, y, and relativeTransform now map through the groups around a node, and geometry changes, appendChild, insertChild, and remove refit the surrounding groups. The refit moves to Scene Graph as fitEnclosingGroups, shared by the canvas (with undo) and the plugin API.
* test(core): pass script-style strokes and typed components in parity tests
* test(e2e): expect Figma's default shape grey in the scene freshness spec
* fix(vue): draw lines by length and angle as Figma does
The Line tool sized a line as the box spanned by the drag. With the stroke a new line now gets, that box drew as a rectangle outline. A line now starts at the press point with the drag length as its width, no height, and the drag angle as its rotation, as Figma's Line tool makes it; Shift snaps the angle to 45° steps, as the docs already described, and a click makes a 100 px horizontal line.
* fix(core): give each new layer its own copy of the default paints
The defaults spread each paint shallowly, so every layer shared the colour object of the module-level default and editing one layer's colour in place changed the next new layer. Copy the paints with the Scene Graph copy helpers.
* fix(core): group, ungroup, and combine layers through shared code in the plugin API
The plugin API wrapped layers, ungrouped, made booleans, and made components from layers with its own code. Ungroup moved the children to the top of the stack, booleans were named "Boolean union", and a component made from a frame cloned its children under new ids. These now run through the editor's shared wrap, ungroup, and boolean functions, with the placement and defaults recorded in Figma desktop 126: a group or boolean without an index goes on top, ungrouped children take the group's place, booleans are named after the operation and filled with the default grey, a frame becomes a component in its place with its children, and any other layer is wrapped in a white component named after it. Undoing a wrap in the editor now returns each layer to its own place in the stack.
* fix(core): group, frame, combine, and make components from the canvas as Figma does
Recorded in Figma desktop 126: a container made from the canvas takes the topmost selected layer's place, Frame selection adds no fill and does not clip, a component wrapped around layers is white and takes a single layer's name, and a boolean is filled like its topmost operand, or its base for Subtract, without strokes. The canvas commands and the plugin API now share the wrap parent check, stack ordering, component rules, and boolean paints, and the plugin API's createComponentFromNode converts groups in place as Figma does. Undoing a boolean returns each operand to its own place in the stack.
* refactor(core): reuse translate when centering pasted layers
* feat: open documents dropped onto the window
Dropping a .fig, .pen, or other readable document did nothing: the canvas drop handler places only images and SVG files and swallowed everything else. The workspace now opens dropped documents in new tabs through the same path as File → Open, passing the file handle where the browser provides one, and reports files it cannot open instead of ignoring them. Images and SVG files dropped on the canvas are still placed.
* fix: classify each dropped file instead of matching File identities
DataTransferItem.getAsFile() may return a new File, so checking it against the canvas files from dataTransfer.files could miss images and SVG files and open them as documents in engines other than Chromium. Each extracted file is now classified on its own; a spec checks that an SVG dropped on the canvas is placed without opening a tab.
* feat: select layers at Figma's click depth
Checked against Figma desktop 126 with the same pointer input in both
editors. A click walks from the page down to the deepest layer under the
cursor and stops at the first layer that is not open: top-level frames
(on the page or in a section) and sections that hold layers, component
sets, and every ancestor of the selection are open. So a click inside a
top-level frame selects its direct child, the empty part of a top-level
frame or section selects nothing, and a selected layer's siblings and
cousins are one click away. Double-click goes one level deeper and
Cmd/Ctrl-click reaches the deepest layer.
A marquee started inside a top-level frame or section selects that
container's layers; from the page, a frame or section holding layers is
selected only when fully enclosed.
* fix(vue): compare marquee hits by canvas bounds
A marquee scoped to a rotated frame mapped only two corners into its space, and page-level enclosure used a frame's unrotated rectangle. Both now compare each layer's axis-aligned canvas bounds with the marquee, so rotated frames and their children are selected by what is drawn.
* fix: match Figma when dragging, drawing, duplicating, and pasting
Checked against Figma desktop 126 with real pointer input. A dragged layer
lands in the topmost unlocked frame, section, component, or instance under
the cursor, following rotation and clipping, and leaves its frame as soon as
the cursor does; groups, boolean operations, component sets, and locked
frames never take a drop, and a layer stays in its group unless it lands on
another frame. Space keeps parents, Shift locks an axis, and Control drops
into auto layout as an absolute-positioned layer. Locked layers stay put.
New shapes go into the frame under the start point, frames and sections take
in the unlocked siblings they fully cover, duplicates land in place (top-level
frames to the right), and paste keeps the copied position, centering an axis
that does not fit the selected frame.
* fix: match Figma for drag edge cases with components, groups, and auto layout
A second round of checks against Figma desktop 126, replaying the same
pointer input in both editors. A component set takes back only its own
variants, and components never go into other components. Groups and
booleans refit their children after a move or nudge, and a group whose
last layer leaves is removed. Pressing inside a selected frame, group, or
component set drags it instead of the layer under the cursor.
Auto layout children dragged out land where they are dropped, drawing
inside auto layout adds to the end of the flow, and wrapped frames insert
on the line under the cursor. Duplicates keep their names, and a main
component duplicates as an instance with Cmd+D or Alt-drag; a multi-layer
duplicate stays in place, and a lone frame in a section counts as
top-level.
* fix(core): refuse new shapes in the locked part of an instance
createShape redirected a refused parent through acceptingParent while keeping coordinates in the original parent's space, and still inserted the layer when the slot claim failed. It now takes the given parent, claims a slot when needed, and throws when the parent refuses children; drawing skips such parents before creating anything.
* feat(lint): suggest converting groups to frames and deleting hidden layers
no-groups and no-hidden-layers now carry suggestions the Lint panel, the
lint_fix tool and editor.applyLintFixes can apply. A group becomes a frame
in place, keeping its id, children, bounds and look; a hidden layer is
deleted with its children. Neither is offered for locked layers or inside
components and instances, and both are checked again when applied.
The editor gains convertGroupToFrame and deleteNodes, which deleteSelected
now uses, and applies lint fixes through a bridge so structure changes and
property updates share one undo step. lint_fix becomes a document mutation
because atomic tools cannot remove layers.
* fix(code): keep canvas edits made while replaced code waits to render
Replacing all the code drops its layer links until the preview links it
again, so a canvas edit in the preview delay could not be patched into the
code and the preview drew over it. Edits made while code waits to render
are now applied again once the preview has linked the code, in the same
undo step, and reach the code like any other canvas change.
* fix(figma-api): default paint opacity and visibility like Figma
Plugin scripts may leave out a paint's opacity and visible; Figma reads
them back as 1 and true. The fills and strokes setters stored the paint
as given, so the Design panel received an undefined opacity.
* build(dev): forward only errors from the browser console
Vite forwards browser logs when an agent starts the dev server. Serializing
a Vue warning's component props walks the editor state and freezes the
tab, so warnings stay in the browser console.
* fix(code): follow values while they are dragged or scrubbed
Live previews change layers without a new scene version, so the code kept
the old value until the gesture ended. The Code tab now follows preview
updates once per frame, as the Design panel does, and goes back when the
gesture is cancelled.
* fix(code): keep canvas edits when the replaced code fails to preview
A failed preview took the canvas edits waiting for it and dropped them,
and stopped recording new ones, so correcting the code drew over them.
The edits now wait for the next preview.
* feat(code): link code to canvas layers and underline design issues
Code in the Code tab and layers on the canvas were unrelated: finding the
element behind a layer, or the layer behind an element, meant reading names.
Generated Design JSX and Tailwind JSX report the layer behind each element
in the order elements open, and edited Design JSX keeps the source line of
every element through the sandbox and renderer, so hovering an element
highlights its layer, Cmd/Ctrl-click brings it into view without changing
the selection the code shows, and errors and warnings from the design check
are underlined on the property that causes them.
* feat(code): explain the Code tab when nothing is selected
With no selection the editor showed a starter frame that read like a real
layer. The tab now says it shows the selected layers' code and offers Write
JSX, which opens the editor focused on the starter template.
* refactor(code): group code-to-layer linking into its own domain
Layer link types, issue mapping, and the hover and reveal behavior move
from the Code panel and a component file into src/app/code/layers, with
useCodeLayers as the panel's entry point, so app code no longer imports
types from components.
* fix(code): underline off-scale gaps after the spacing rule renamed its property
* feat(code): mark the layer of the element around the cursor
Hover highlighting and ⌘-click reveal replaced by one model: the element
around the cursor marks its opening and closing tag names and outlines its
layer on the canvas while the editor has focus. ⌘-click also collided
with CodeMirror's add-a-cursor gesture. Read-only Tailwind JSX now takes a
cursor so it links the same way.
Leaving the editor now ends a live Design JSX edit as one undo step.
Before, canvas edits made after typing never reached the code until the
tab was reopened, and their undo entries landed before the edit's.
* feat(code): sync the Code tab and the canvas both ways by patching
Canvas edits now patch the Design JSX a person wrote instead of waiting
for them to leave the editor: each linked element remembers the layer as
Design JSX last wrote it, and a canvas change rewrites only the attributes,
text and child elements that differ from that base, as CodeMirror changes
that keep the cursor, comments, formatting and history. Attributes written
as expressions are never overwritten; the code marks them when the canvas
now differs. Untouched code is regenerated with a minimal text change.
Code edits update layers in place: the new render is reconciled into the
existing layers (reconcileRenderedLayers), which keep their ids, so links,
selection and canvas edits survive typing. Each edit is one coalesced undo
step, replacing the restore-and-rerender preview and the commit on blur.
* feat(code): patch reordered layers and aliased properties in edited code
Reordering layers on the canvas now moves their elements in code a person
wrote: each child element and the blank lines and comments above it form a
block kept as written, and the children are written again in the new
order, staying linked. Children that cannot move safely, such as a loop
between them, keep their order and are marked.
Properties accepted under several names now come from one alias table in
the Design JSX schema, which the renderer resolves through and the patcher
and issue underlines use, so a canvas change to `w` patches `width` where
the person wrote that, instead of adding a second attribute.
* feat(code): keep the cursor in moved code and patch values written in style
A reorder rewrites the children span in one change, which collapsed a
cursor or out-of-sync marker inside a moved element to the span's edge.
The patch now carries where each block moved and places selections and
markers inside it at their new position.
Properties the renderer also reads from style={{ … }} come from a table in
the Design JSX schema instead of a hand-written list, keeping the rule
that an attribute under any of its names wins. The patcher uses it to
update a value written in style where it is, as a number or a px string
as written; values the renderer cannot read, such as '50%', are marked.
The layer patcher is split by concern: syntax helpers, attribute and
style patches, child patches, out-of-sync state and transaction assembly.
* feat(code): show the code's layer on the canvas as a tinted box
The layer of the element around the cursor used the canvas hover slot, so
moving the pointer over the canvas replaced it and the two read the same.
It now has its own shared editor state, codeFocusNodeId, drawn as the hover
outline over a light tint in every pane: hover stays an outline and the
selection keeps its handles, without borrowing the dashed outlines that
already mean component sets, drag parents and ghosts.
* fix(code): write added and removed layers when a reorder cannot move the code
When children could not be moved, such as two written on one line, the
patch marked the order and returned before adding or removing elements,
so a layer created in the same change never reached the code. It now
marks the order and still writes additions and removals.
* refactor(design-jsx): format the rebased layer description and stroke aliases
* feat(code): mount the layer-linked code editor through useCodeMirror
Master moved the code editor onto the shared useCodeMirror composable.
Its layer links, issue underlines, canvas patches, minimal text updates,
autofocus and read-only cursor now sit on that composable instead of a
hand-mounted view.
* feat: check designs live with a Check panel and canvas issue markers
Design lint only ran from the CLI and AI tools, and its rules were too noisy
to show continuously: on a real imported page 786 of 888 layers had a
warning. The rules now report where a finding is actionable (a hardcoded
color only when a variable matches it, nesting only where the limit is
crossed, instance sublayers through their main component) and carry
structured data, and Recommended keeps warnings for likely problems.
The app checks the current page after edits settle. The Check tab groups
issues by rule with hover highlighting, reveal on click, and one-step
variable binding. Errors and warnings are marked on the canvas with
clustered markers that roll up to visible ancestors when zoomed out; markers
explain themselves on hover, open Check on click, and toggle with
View > Design issues.
* fix: keep the right panel and markers stable
The Check tab made the right-panel tab row overflow at common window widths,
so focusing the zoom menu scrolled the row and shifted the panel. Code and
AI tabs now drop their labels to screen readers when the row is narrow.
Touch target names are matched as whole words: "Rectangle" contained "cta"
and marked every rectangle. Markers also stay drawn during interactive edits
instead of blinking while a value is scrubbed.
* fix(ui): show right panel tab labels whenever they fit
* fix(ui): name the design check tab Lint and keep panel tabs consistent
The tab was an unlabelled icon between labelled Code and AI tabs. It is now
Lint, with the same icon and label anatomy as its neighbours, and its icon
takes the severity color instead of a count badge. All labelled tabs show
their labels when the row fits and drop them together when it does not.
* refactor(ui): build the Lint panel from shared components
Issue groups use AppCollapsible, actions use AppButton, and the severity
filters are a Reka toggle group with keyboard navigation. Issue rows no
longer nest a button inside a button. Panel state, visibility and the
focused-issue scroll live in useDesignCheckPanel, the rules menu is its own
component, and rule preferences change through preference actions.
Severity ordering reuses Core's ranking, detail numbers follow the app
language, and the check debounce uses useTimeoutFn.
* fix(lint): check the WCAG AA touch target size in the Recommended preset
Recommended flagged a 394 × 39 input because it required the 44 × 44 AAA size. It now checks the 24 × 24 AA minimum through a minSize option; Strict and Accessibility keep 44 × 44.
* feat(lint): fix design issues from rules, the Lint panel, the CLI, and agents
Rules attach fixes as data: a safe fix keeps the design as it looks (bind a
color to the variable it matches, round subpixel geometry that layout does
not own), a suggestion changes values (snap radius and spacing to the
scale, raise small text to the minimum). One Core applier re-validates
each fix against the current graph and merges changes per layer.
The Lint panel offers a fix per row and Fix all for safe fixes as one undo
step; openpencil lint --fix writes the fixed document; the lint and
lint_fix tools expose the same to MCP and AI chat.
The design-check spec's Close button is now 24 x 20: at 24 x 24 it passes
the WCAG AA touch target size that Recommended checks.
* feat(lint): pin issues outside the view to the canvas edge
Errors and warnings on layers outside the viewport had no marker, so a
check could report issues nobody could see. They are now pinned to the
canvas edge where a ray from the viewport center toward them leaves it,
with a chevron pointing their way; pins in one direction merge like
markers. Hovering lists them under the direction they lie in, and
clicking reveals and opens the most severe, nearest one.
Pins keep clear of UI floating over the canvas: the toolbar marks itself
with data-canvas-obstacle, and canvases report such rectangles to the
renderer through getOverlayObstacles each frame.
* feat(lint): mark layers with design issues in the Layers panel
Like an IDE marks files with problems and the folders holding them, a
layer with errors or warnings shows the most severe as an icon, and a
collapsed layer with issues inside it shows a dot in that color.
Suggestions stay in the Lint panel, as on the canvas, and the marks
follow the View → Design issues toggle.
* feat(lint): show issues per page and across the document
Loaded pages beyond the current one are now checked in the background,
one page at a time while the editor is idle, and checked again only when
an edit touches them; pages a large .fig file has not loaded are left
alone until opened rather than forced in. The page list shows each page's
errors and warnings like an IDE's problem count, and the Lint panel gains
a Document scope that lists every page's issues, tags the ones on other
pages, and switches to a row's page when it is opened.
* test(lint): use the core-tests alias and no comma operator in lint tests
Master now rejects ../../ imports and the comma operator in tests.
* refactor(app): create the Lint session with the editor store modules
The composition root passed its line budget once master added recent
pages; the Lint session belongs with the other per-editor services that
the modules factory creates and disposes.
* docs(changelog): keep master's latest Unreleased entries
* fix(vue): keep the command palette open when a command opens a step
CommandPaletteRoot emitted select for every item, including one that only opens its children, so a host that closes on select closed the palette instead of showing the step. useCommandPalette.select now reports whether a command ran, and the root emits only then.
Disabled items were marked only with Reka's data-disabled; expose aria-disabled so assistive technology announces them.
* feat(app): jump between pages from the command palette
The palette had no way to reach a page. It now lists the pages visited recently in the tab, offers a Go to page step with every page, and finds any page by name.
Recent pages are tracked per editor session from page changes and reset when the document is replaced. Palette items can be search-only, so pages beyond the recent ones appear only when the query matches them. The divider-page rule moves out of PageListRoot so the palette skips dividers the same way, and useCommandPalette is exported from the package root.
* feat(canvas): draw agents' cursors as outlined sparkles
Editor state's remoteCursors becomes presenceCursors with a kind, since the list now includes local agents. People keep the filled arrow; an agent is a sparkle outlined in its owner's color, with an outlined name pill, so whose agent it is reads from the outline. Cursor drawing moves out of the pen overlay into canvas/overlays/presence.ts.
* feat(app): publish AI agent presence to collaborators
The built-in chat now appears as an agent with a callsign while it replies, at the nodes its tools touch on the run's page, and goes idle (off the canvas) when the reply ends. Agents live in a per-document presence registry and are published in their owner's awareness state, so collaborators see each other's agents in the owner's color; the payload is metadata only.
Peer awareness was cast without checks. It is now validated with Valibot, invalid fields are dropped rather than the peer, and names, selections, and agent counts are bounded.
* feat(app): follow agents and list them in the share panel
Following lived in collab and only knew people. It moves into the presence registry with a person-or-agent target, so you can follow anyone's agent, including your own outside a room: the view goes to the agent's page and keeps its cursor centered, stays attached while it idles between replies, and lets go when it leaves. A new editor action, centerOn, replaces reading the canvas size from the DOM. Peer cursors keep their zoom so following a person still matches it.
The share panel lists everyone in the room with their agents, each with its status, page, and a follow toggle, and your own agents can be renamed inline. CollabPanel moves to collab-panel, and the two-browser relay helpers move out of the collab spec into tests/helpers/collab.
* feat(app): show who works on each page
Agents now publish the page they work on, set when a reply starts on its pinned page and moved by switch_page, so a page is marked before the agent's first edit. presenceByPage groups people and working agents by page.
The Pages panel marks those pages with people's dots and agents' outlined sparkles in their owner colors, the command palette names who is on each page, and the chat says which page a reply is working on, with Go to page, while you view another one.
* docs(collaboration): list the agent model among shared presence
* test(app): stories for page presence markers and the chat's run location
The run location notice reads app state, so it moves into
useChatRunLocation and the component takes the agent and page as props.
* test(vue): a canvas story for presence cursors
Storybook now serves CanvasKit, so a story can render the real canvas:
people's arrows and agents' outlined sparkles, with controls for names,
colors, and zoom.
* feat(canvas): mark agents with a sparkle label instead of a sparkle cursor
A sparkle on its own did not read as a pointer. Agents now point with
the same filled arrow as people, in their owner's color, and their
outlined label starts with a sparkle.
* refactor(app): split the collaboration theme by component
One 18-slot theme served five components that each used a few slots,
with variants that applied to one slot. Avatars, the share button, the
presence list, page markers, and the mobile presence popover now have
their own themes, exported as tv() like the rest of src/theme.
* fix(app): truncate an agent's status before its name in the presence list
In a narrow share panel the status kept its width and the callsign
shrank to its first letter.
* feat(app): right-align page badges in a trailing area of the page row
Presence markers followed the page name. The row now has a trailing area,
right-aligned with its own spacing, where markers and later page badges
go.
* fix(app): key page markers by person or agent, not by name
Two people with the same name on a page, such as two Anonymous peers,
gave page markers duplicate keys. Entries now carry a stable id.
* fix(vue): keep the command palette open when a command opens a step
CommandPaletteRoot emitted select for every item, including one that only opens its children, so a host that closes on select closed the palette instead of showing the step. useCommandPalette.select now reports whether a command ran, and the root emits only then.
Disabled items were marked only with Reka's data-disabled; expose aria-disabled so assistive technology announces them.
* feat(app): jump between pages from the command palette
The palette had no way to reach a page. It now lists the pages visited recently in the tab, offers a Go to page step with every page, and finds any page by name.
Recent pages are tracked per editor session from page changes and reset when the document is replaced. Palette items can be search-only, so pages beyond the recent ones appear only when the query matches them. The divider-page rule moves out of PageListRoot so the palette skips dividers the same way, and useCommandPalette is exported from the package root.
* fix(vue): list every item in a command palette step
The result limit also applied to a step's unfiltered list, so Go to page showed only the first 12 pages. A step the user opened now lists all of its items until they search; search results and the top-level list keep the limit.
The palette spec's page setup and current-page observation move to tests/helpers/pages as a setup mutation, a probe, and a Pages-panel driver.
* test(pages): match page rows by exact name
* refactor(app): express page lists with es-toolkit
Recent pages are take(uniq([visited, ...previous]), max); the palette builds its lookup with keyBy and its lists with without, compact, take, and difference instead of hand-built maps, sets, and slices. Tests count with range.
