Eleven more roots drop w_full: the docked ActionBar, MessageBubble's
three arms, PromptInput, TitleBar, Tabs, the horizontal Divider with
and without a label, DropZone and Playlist. Their hosts in the crate
are blocks or flex columns. The gallery's docked ActionBar sits in an
items_center column, so the demo gives it the width.
AspectRatio keeps w_full, and AGENTS.md says why: taffy 0.9 follows a
ratio from a set width, not from a stretch, and without one the image
gallery's tiles and the ratio demo collapsed.
Every page and scripted state was shot again at full width and at
280px and compared with the shots from before T44a. Nothing collapsed
or shrank. The mail reader's attachments now wrap side by side, as
their row asks.
145 component roots drop w_full, the early returns included. Three
field rows keep it, Input, InputGroup and TagInput: stretched without
a width, taffy 0.9 laid the field's flex_1 share at no width in the
template picker at 280px, and the placeholder drew nothing. Container
keeps it, since mx_auto needs a width to fill.
Hosts that relied on a root's width now give it: MessageList boxes
each row at the list's width, the splash gives its bar the column's,
and test stages that mount a component as the window's root sit in a
size_full box. Tests hold a narrow row across the list and the splash
bar across its column; each goes red without its fix.
The gallery gains --narrow <px>, which lays each page in a padded
card at that width and shoots it without its script. The page
header wraps: the title takes the room and the theme switcher drops
below, where a long summary used to push it past the edge. A file
panel step waits for the panel to become key instead of a fixed
pause, which lost a race in a capture.
The audit now holds fg_subtle on active, a selected row's fill, and
each syntax color over the editor's surface, a code block and the
current line. What it found is fixed at the source: fg_subtle is
#696764 light and #94928f dark, syntax.comment follows it, and the
light number, constant and attribute darken to #a3591b, #aa5529 and
#9f5d12. The token viewer adds avatar and container sizes, draws a
container at its share of the widest so it stays in its row, and
names what it shows: the shared colors and scales. Tests pin every
variant, the hue each chart row reads and the code rows.
DesignTokenViewer shows every token of the theme in the mode shown,
named as code reads it: colors with their hex, syntax, chart and
terminal colors, the type scale, radii, control and icon sizes,
elevations and spacing. A11yChecker audits each text color over the
surfaces it sits on at 4.5:1 and the focus ring and chart hues at
3:1, failures first. The audit found fg_subtle under 4.5:1 on hover
and overlay; it is #6f6d6a light and #8c8a87 dark now, and a test
holds all four Ely palettes to the audit. IconBrowser points to
forms::IconPicker and the ScreenshotTest Harness to the gallery's
capture, each with a section on the tooling page.
FpsMeter keeps the stamp before the last second, so a frame longer
than the span shows as the worst and a bar. The inspector's panel, a
second root out of the app's scope, sits in a FocusScope of its own,
so Tab goes on from Pick. EventLogger takes key downs through an
interceptor, which runs before bindings, and marks its box with a key
context to know focus is inside, so a field's Backspace and Enter log.
Tests hold the stall, Tab both ways through Pick, bound keys in a
field, a key while focus is outside, newest first and a bare border.
install_inspector draws gpui's debug inspector in Ely's look: a panel
with the picked box's source, ids and box model, and its margin,
border, padding and size drawn over the page through raise, since the
panel scrolls. FpsMeter counts frames on the executor's clock and
colors each by the frames it missed. RenderCounter counts the renders
of the view that draws it. EventLogger lists the input that reaches
what it holds, its canvas laid first so a child's stop hides nothing.
tooling::Playground lays a preview beside its knobs, each a switch, a
choice or a number that edits one property; the preview redraws from
the settings, which fail on a name or kind the knobs lack. The gallery
app is the ComponentGallery; its page 43 shows both.
misc::ExportDialog offers the owner's formats as cards and hands the
chosen one over for the owner to write. misc::ImportDialog maps the
file's columns to the app's fields, matched by name to start, over a
preview, and asks for each required field's column. misc::CsvImporter
reads CSV as RFC 4180, lets the first row name the columns or not, and
maps it through the ImportDialog into records; text that does not read
says why.
WKWebView takes AppKit's first responder on a press and gpui's view
never asks for it back, so typed text went to the page for good. The
web view now hands it back through wry's focus_parent on every press
gpui gets and when its page drops. The gallery proves it with a native
key after a press on the page. in_view builds only where it is used,
its test covers a box that straddles the view's top, and the embed's
frame takes the card's bottom corners.
misc::WebView lays wry 0.57's child WKWebView over the window at its
box, following it from a canvas in prepaint and hiding it out of view;
it loads an address or the owner's HTML, which makes it the HTML
preview. misc::IframeEmbed frames a page under its address with Open
in browser. EmbedCard points to chat::LinkPreviewCard, ShareSheet to
buttons::ShareButton; PrintButton is blocked, gpui 0.2.2 has no print
API.
Tests now press Decline and the scrim, see focus return to the opener
after Accept, see necessary cookies stay on and off the Tab path, and
see the license list mark its row and read each version and license.
lists::ListItem marks its description and selected state for tests.
forms::Switch's label wraps in its own block, as Checkbox's does.
Ely's own row in the gallery shows both of its license texts.
misc::LicenseViewer lists what a product ships with each license beside
the chosen one's text. misc::ConsentDialog asks for a box before Accept
and answers each way out once, accept or decline. misc::CookieBanner
takes Accept all, Reject all, or a switch per kind through Choose, which
turns into Save choices on its focus. ChangeLog Viewer points to
data_display::Changelog.
misc::Poll turns to results once the owner holds the vote, with Change
vote on Vote's stop. misc::Survey asks on one page and sends when each
question is answered, thanking in Submit's place and focus. misc::Quiz
checks, goes on, scores and starts again on one button. misc::Flashcards
turn on a press and go round the deck, each face fading in.
misc::QrCodeScanner reads QR codes with rqrr 0.11 from the frames the
host hands in, one at a time off the main thread, and hands each code
to the owner once. misc::Captcha shows the owner's picture over an
answer field that empties and keeps focus with each answer; the owner
says how it stood. BarcodeDisplay, Signature and Rating Widget point
to their homes.
A calculator result stays in the sum as `a`, handed to evaluate with
its whole value, so 1 ÷ 3 = × 3 = gives 1; sign turns it and delete
takes it. Equals waits on a dangling operator. The converter's reading
wraps in its box rather than ending in an ellipsis, and tests hold
Control, the = key, a point after a result and the six digits.
misc::Calculator works a typed sum in forms::evaluate's precedence,
from a pad or the keyboard; Enter is equals while the calculator
itself has focus, and Escape clears or passes on. misc::UnitConverter
reads an amount in another unit across seven kinds, with a swap.
Both show numbers through format::significant, which rounds through
Rust's exponent form.
The stopwatch's second button reads Lap while running and Reset once
paused, on one focus handle, and Reset hands focus to Start, so no
press leaves focus stranded. Lap rows carry selectors; tests hold
their order and times, count the tickers' wakes, and a WorldClock
without places fails.
misc::Clock shows the time in a zone, the system's unless told, as an
analog face with hour marks and three hands over its digits and a
label; it wakes its view at each whole second of the wall clock, and
only while the owner passes no moment. misc::WorldClock lays places in
rows: a small face, the place, how its day and hour stand against home,
and its time. misc::Stopwatch runs on the executor's clock in tenths,
holds while paused, marks laps while running and clears once paused;
Start and Pause share one button and its focus.
ChoroplethLayer washes each area by its value, keyed by its id or a
property's text or number, on one hue's scale from its faintest at the
least value to its strongest at the most; an area without a value reads
as no data. ChoroplethMap lays it on the owner's map, with or without
tiles, and puts a legend of the scale and of no data in the corner; a
value that matches no area is logged once. WorldMap washes Natural
Earth's 110m countries, bundled trimmed by scripts/countries.py, by ISO
3166 alpha-2 code, and fails on a key that is no code. A shape now
paints as one fill and one edge path per world in view.
MapView takes layers over its tiles and under its pins. RouteLine runs
along places the short way across the date line. read_geojson reads RFC
7946 to features, strictly: a position past the globe, a line of one
position or a ring that does not close fails with its reason, and a
feature placed nowhere keeps no geometry. GeoJsonLayer washes areas as
one path per polygon, so holes stay open, outlines them, strokes lines
and dots points. GeoHeatmap spreads weighted places in a quartic kernel
over small cells, scaled to the densest spot in view. Lines and areas
unwrap across the date line and repeat on every world in view.
cluster_markers gathers pins by squares of the world, so a pan keeps
each group; a cluster shows its count, and its press shows its members
whole, never farther out. A zoom that may regroup them hands a focused
pin's or cluster's focus to the map.
maps::MapView lays the host's tile for each zoom, column and row in Web
Mercator, the nearest cut scaled past the zooms it serves, on whole
pixels. gpui packs pictures in its atlas without padding and samples
them linearly, so each tile draws with a one-pixel rim copied from its
own edge, one of its pixels larger each side and clipped, and no seam
shows. A drag, the wheel or the arrows pan; Command-wheel, + and - or
its buttons zoom about the pointer or the center; the owner keeps the
viewport. MapMarker pins take a press and Enter when the map hears
them; MapPopup opens toward the map's larger half and stays inside it,
closing by its button or Escape. LocationPicker picks the place under a
center crosshair; CoordinateDisplay writes degrees or degrees, minutes
and seconds with tabular figures and a copy button. The gallery's tiles
are Natural Earth's countries, cut z0 to z3 by scripts/tiles.py.
blocked() laid its text as a flex item beside the dot, and gpui measures
a text item's least width unwrapped, so a long note ran past its column
and the dot shrank to nothing. The text now sits in a flex_1 block with
no least width beside a dot that never shrinks, which rests on the first
line, as Alert holds its icon. The a11y note and the motion page's
Lottie note wrap inside their columns. A failed hue check names both
charts in hex.
i18n::SkipLink holds a Tab stop in flow at zero size, first where it
sits, and while focused raises a pill over the page; Enter, Space or a
press hands focus to its target. gpui orders stops by tab_index before
paint and registers none for an invisible element, so the stop stays in
flow and only the pill is raised. Theme::set_color_blind_safe swaps Ely's
chart hues for a set fitted to stay apart under Machado's protanopia,
deuteranopia and tritanopia; a test holds every pair 0.10 apart in Oklab
and each hue 3:1 on its page, and red against green shows the measure
bites. KeyboardNavigationHelper points to interaction::RovingFocus. The
announcer, labels and screen-reader text stay blocked: gpui 0.2.2 has no
accessibility tree, and nothing here is trusted to observe VoiceOver.
The i18n tests move under src/i18n/tests.
gpui sets no paragraph direction, so CoreText took a Hebrew line whose
first strong character was Latin, or the left-to-right mark of a signed
number, as left to right and swapped its parts. I18n::text now leads a
right-to-left message with U+200F; the number keeps CLDR's U+200E, so
its sign stays at the digits' left. The demo adds a change that opens
with a signed number, in every catalog; under Hebrew it lies at the
line's right end. A test holds the marks on a message that starts with
a number and one that starts with a Latin name.
gpui 0.2.2 wraps shaped glyphs in the order they are drawn, so a
right-to-left line that wraps comes out garbled. The demo's Hebrew
lines are Ellipses, which cut by characters, and an Ellipsis now sits
by its text's alignment, so a short line under text_right lies at the
right; the editor's completion details take the side they ask for. A
right-to-left locale leads a minus with a left-to-right mark, as CLDR
does, so the sign stays at the digits' left inside Hebrew. en-US and
de-DE write CLDR's two-digit year. The repeated-key and second-catalog
guards have tests.
i18n::I18n is a gpui global holding the shown locale and one catalog of
messages per locale. text fills each {name} from its arguments; a
missing key, argument or catalog fails, and every catalog holds the
first one's keys. Locale writes numbers with its separators and dates
in CLDR's short numeric form; Hebrew replaces Arabic, whose Egyptian
digits Ely does not write. Direction::row mirrors a stack and
Direction::align sets text against the reading side. The gallery's
chapter 40 shows the messages in seven locales, every locale's number
and date, and a file list that mirrors under Hebrew.
Windows caption buttons take the bar's height less its hairline, a new
token, instead of their row's, so they keep their height beside caps
that wrap below them. A title bar's title is an Ellipsis: on Windows it
takes the free width before the buttons and gives way; a centered title
sits inset past the lights on both sides. The controls never shrink.
Tests hold a long Windows title's close button inside a 280px bar and
wrapped caps inside their row.
theme::Platform moves out of typography and shell's ControlsStyle folds
into it; the theme's platform starts as the system's. Window buttons Ely
draws, the title bar's layout and every key cap follow it, secondary
included, through typography::keys::keystroke; a title bar whose buttons
the OS draws follows the OS. primitives::IconTheme lays an owner's rules
by file name and extension over Ely's map, for every file icon.
shell::Vibrancy fills a pane with the palette's new glass, translucent
so a window opened Blurred shows its backdrop, solid under high contrast.
gpui 0.2.2 has no Mica; that line stays blocked.
settings::read_vscode_theme reads a VS Code color theme, comments and
trailing commas and all: its type picks the mode, its colors and token
scopes name what they give, and the rest keep Ely's palette of that mode.
settings::ThemeImporter takes one dropped or browsed for, shows its name,
mode and count, and hands it over on Apply; a file that does not read
says why. theme::syntax_themes offers Ely's code colors, Quiet and Paper,
chosen through settings::SyntaxThemePicker, radio cards with a line of
code in each palette. A card's words now shrink as a plain block, so a
preview wraps inside the card at 280px.
settings::ThemeEditor lays a theme open: density, corners, text size,
high contrast and reduced motion, then twelve colors of the mode shown,
each a swatch that opens a picker beside its hex; each change hands the
owner a whole draft. Theme::set_palette takes an owner's palette per
mode, the colors fading to it when the mode shows; Theme::palette names
the palette the shown mode fades to; Palette::token_mut and
Syntax::token_mut reach a color by its field's name. The gallery's
theme page applies the editor to the whole gallery live, with a way
back to Ely's theme.
RovingFocus keeps a row or column of items behind one Tab stop: the
arrows walk focus, Home and End reach the ends, Enter or Space presses,
and a press moves the stop without taking focus. ScrollSync keeps boxes
at one place along an axis: the pane a wheel turned leads, and a canvas
ahead of the panes copies its place before they draw. SelectableList
moves its cursor to the row that starts with the letters typed, the
letters joining within a pause and a Command letter left to the app.
forms::History becomes public as the undo manager. The gallery shows
gpui's own key bindings, a two-stroke chord waiting on its first
stroke, uniform_list, autofocus and the focus ring.
Resizable sizes a box from its right and bottom edges and a grip at
its corner, within its least and greatest size; the grip is a Tab stop
whose arrows resize a step. Rotatable turns an svg to its angle inside
a ring whose knob a drag moves, Shift snapping to 15 degrees, with the
arrows turning it a notch. SelectionArea selects items with a band
drawn on empty space, a press, Command or Shift to add, and a cursor
the arrows walk with Space to add or drop; Escape clears and
Command-A takes all. The gallery shows gpui's own drag and drop, drag
preview, double press and wheel zoom, with pointers for Sortable,
LongPress and PanZoom; pinch stays blocked, gpui 0.2.2 forwards no
magnify event.
HelpPanel lists its articles in lists::SelectableList: the list is one
stop whose cursor scrolls into view, and Enter or a double press opens
an article, focus going to All articles as before. SelectableList now
activates on Enter's release, armed by its own press, as the palette
and menus pick: an activation that moves focus left the release to
press what took it, here the way back. ContactSupport cuts a long
address in the middle and puts a Copy beside it. The lists tests move
into a folder, the release tests on their own.
HelpPanel searches articles and opens one, its body in Markdown, with a
way back; focus follows to All articles and back to the search, a
link to help:<key> opens another, and Contact support and Keyboard
shortcuts wait at its foot. KeyboardShortcutCheatsheet puts
settings::KeyboardShortcutsList in a dialog with its search focused;
WhatsNewDialog puts data_display::Changelog in one with Got it.
FeedbackWidget asks how it is going with four faces and a note, and
thanks. ContactSupport sends a topic and a message, spins while the
owner sends, and empties the message with focus back in it. InlineHelp
is a quiet line with Learn more. HelpTooltip moves to primitives,
where FormLabel's help mark shows it; ToggleGroup keys its toggles by
its own id. EmptyStateWithAction points to feedback::EmptyState.
OnboardingWizard runs a first run on navigation::Wizard without its
numbered steps: "Step 2 of 4" over a bar in as many parts, the step's
title, line and content, Back and Next once ready, Finish last, and
Skip for now. Hotspot pulses on a dot that opens a tip on a press or
Enter, with Got it. FeatureHighlight names something new under a New
badge, with Try it and Not now, and rises in. SetupChecklist counts
first things to do in words and a bar, offers Start on each left, eases
a check in as one gets done, and offers Hide once all are.
navigation::Wizard now keys its buttons, steps and motion by its own id
and takes on_step and on_finish at render, failing loud without them.
A Meter's name takes the free width and ends in an ellipsis while its
count stays whole, so a long quota name keeps "9 of 12 seats" inside a
280px box. `expiry` says why it refuses a date, and Expires reads
"There is no month 13." apart from "This date has passed.". Tests now
cover an American Express card's fifteen digits and four-digit code,
the address emptying once an invitation goes, a quota past its limit,
and a prompt with benefits standing as a paywall and one without as a
line.
SubscriptionCard shows a plan with its state, price and what comes
next, a way to change it, and Cancel after a second press or Keep plan
once canceled. UsageQuota gives each limit a meter and a line of how
much, or how far past. PaymentMethodForm tells a card's network from
its number, checks it with Luhn, and saves once the number checks out,
the month is ahead, the code is whole and a name is given; it rests
while the owner checks. BillingHistory lists bills with their state and
a download; UpgradePrompt stands as one line or as a paywall.
TeamMemberTable changes a member's role through RoleSelector and
removes after a second press, the owner staying; InvitationList
invites by a reading address with a role and resends or revokes.
ProfileCard shows someone at a glance; ProfileEditor edits a profile
seeded by its owner and saves once it changed, has a name and an email
that reads, with a way to put it back. AccountSwitcher and
WorkspaceSwitcher show the one in use in a row that opens a menu of the
others and a way to add one; UserMenu opens from an avatar with who is
signed in, the owner's rows and Sign out, through the new
menus::menu_under. SessionList puts this device first, signs others
out one by one or all after a second press. ApiKeyManager lists keys by
their ends, makes one by name and shows its secret once.
LoginForm takes an email and a password, keeps one signed in on a box,
and signs in on Enter once the address reads and a password is typed;
a failed try says why above Sign in. SignupForm ticks a new password's
rules as they hold and waits for all of them and the terms.
OAuthButtons offer each provider, one spinning while the rest rest.
MagicLinkForm and ForgotPassword send a link to an address and, once
sent, say where it went and offer it again. TwoFactorInput takes a
six-digit code at once and, after one fails, clears the boxes through
forms::PinInput's new attempt, keeping its focus. The Account chapter
splits into sign-in, profile and access, and billing and team.
SettingsLayout lists sections down the side and shows the open one, the
list going above the page in a narrow box; SettingsSection and
SettingsRow title and hold settings, a row's control wrapping under its
name. SettingsSearch finds a setting by its name or words and opens its
section. ThemeSelector, AccentColorPicker, FontSizeControl and
DensitySelector set the look; KeyboardShortcutsList finds shortcuts by
every word; ProxySettings, PrivacySettings, NotificationSettings,
StartupSettings, StorageSettings with its clear, ImportExportSettings,
ResetToDefault, FeatureFlags and DeveloperModeToggle fill the rest.
Every handler a control needs is required and fails loud when missing.
ColorPalette wraps its swatches in a row capped at its columns, so it
keeps their size in a box sized by its content, and its swatches carry
the palette's id. ThemeSwitcher points here: src/theme sits under the
chapters that draw with buttons.
DashboardGrid lays widgets on columns: a tile's strip drags it and its
corner resizes it a cell at a time, others move down and rise to fill
gaps, a focused tile steps with the arrows, and under the theme's
stack_below width the tiles stand in one column. DashboardCard frames a
widget. AlertList acknowledges a firing alert from its row and opens
one on Enter; IncidentCard shows an incident's gravity, phase and
updates. UptimeBar, ServiceStatus and HealthCheck show what is up, a
check's detail wrapping under its name when narrow. EventStream keeps
kinds and holds the list while new events count up.
RefreshIntervalSelector and DashboardFilterBar set the window, the
filters and the refresh. StatCard, MetricsChart, ResourceGauge,
LogStream, TraceWaterfall, SystemMonitor, ProcessTable and NetworkGraph
point to their homes; the maps wait for T41.
RegexTester tries a pattern with its flags against a sample, washes
each match and lists it with its groups, zero-width ones too; a pattern
that does not compile says why. Encoder turns text into Base64, URL or
hex and back, says why a decode fails (Base64 pads end the text, twice
at most) and copies the result, drawn through typography::literal so no
ligature hides a character. ColorContrastChecker measures text on a
background, translucent text as it blends, and names the WCAG levels
met. ContainerList starts, stops, restarts and opens containers, each
button shown when the owner handles it. PodList sorts pods by any
column, ages by length through tables' new Cell::Duration, and narrows
them by namespace. ResourceMonitor shows each reading's latest value
beside its sparkline and, with a limit, how full it is.
WebSocketConsole draws its log through chat::MessageList, so it holds
at the newest message. EnvironmentSelector opens a secret for its own
environment only. CollectionTree takes on_move and devtools::moved
applies a drop; the gallery opens a saved request into the builder and
moves them. Tests cover the builder's refill, Send at rest, Bearer
sign-in, the indented body, the eye, a field's pick path and the log.
ApiRequestBuilder builds a request: its method and address, then tabs
for the query's pairs, headers, body and sign-in, with the address that
goes out under the field, the environment's {{variables}} filled in or
the missing ones named. Send hands the owner the request. The query's
pairs go through forms::KeyValueInput. ResponseViewer shows an answer's
status in its class's tone with its words, its time and size, then its
body, JSON indented, or its headers in a HeadersTable.
EnvironmentSelector picks a set of variables and masks secrets until
their eye opens them. CollectionTree holds saved requests in folders;
Enter opens one. WebSocketConsole shows a socket's messages, each
marked sent or received with its time, and sends on Enter while the
socket is open and the field holds words. GraphQLExplorer browses a
schema beside a query and its variables; Run waits for variables that
read as JSON and the answer shows as a tree.
A document reads into one value, Datum: JSON through serde_json, its
keys now kept in their written order, and YAML's block style through a
small reader that says which line it could not read. JsonViewer and
YamlViewer draw it as one tree: each key with its value, maps and lists
with their counts; a search keeps what holds its words and opens the
way; Enter on a value copies its JSONPath. XmlViewer reads elements,
attributes and text and says where tags cross. JsonEditor writes JSON
in the code editor with Format and Minify and says whether it reads.
DocumentViewer is JsonViewer.
QueryPlanViewer's step column takes the label width and the table
scrolls sideways past its least width; TableStructureEditor's rows
stretch to a least width that scrolls sideways; RedisKeyBrowser's
columns wrap below each other inside 280px. The form's rules are pure,
parse_port and ready, with unit tests; gpui tests cover saving, a new
connection refilling the form, another engine bringing its port, and a
press on a row's button leaving the row alone.
A new chapter, src/devtools. ConnectionManager lists saved connections
with their engine and address, or why one failed, and connects on Enter;
ConnectionForm fills a connection with a port checked from 1 to 65535,
tests it and saves it. SchemaTree shows schemas, tables, views and
fields with keys marked; ERDiagram draws tables and their foreign keys
on NodeGraph, whose fixed wires show only the sockets that hold one.
QueryHistory finds past runs and runs one again; QueryPlanViewer shows
each step's share of the cost. TableStructureEditor edits fields in
place; IndexManager lists and draws up indexes; RedisKeyBrowser finds
keys by glob and lays out each type. QueryEditor is editor::CodeEditor,
whose lexer now knows SQL's words, and QueryResultGrid is
tables::DataGrid. lists::row_action keeps a row's button its own.
NodeGraph joins Nodes by wires between typed Ports: a title drags a
node, a drag out of an output lands on an input of the same kind, an
input takes one wire, and a press on a wired input lifts its wire.
Links join shapes on the plane and follow them, straight or at right
angles, with an arrow and words; the Connector tool draws them and the
Note tool drops a sticky note. A double press with Select writes on a
shape. FlowChart draws Steps as ellipses, boxes and diamonds with their
words. MindMap lays topics out from a root, half to each side, and asks
the owner to add, remove and rename by key. Whiteboard keeps its own
tool, view and selection over a board it hands back after each change.
Painting moves to canvas::paint; a press on the tool layer goes through
canvas::press, and the layer focuses itself and asks to delete.
LayerPanel lists the canvas's layers topmost first on lists::Tree: a box
shows or hides each, F2 renames, a drag restacks into a new paint order.
InspectorPanel edits the one selected shape's frame, fill, visibility and
lock. AlignmentToolbar lines up or spreads the selection through
`aligned`. AssetPanel finds shapes by name in a picks grid, each drawn
to fit its tile. ColorPanel, ShadowEditor, BorderEditor and
TypographyPanel edit a look; GradientPanel is forms::GradientEditor.
ConstraintsEditor pins a shape to its frame, with `Constraints::placed`;
AutoLayoutControls sets flow, gap, padding and a place grid, with
`AutoLayout::laid`; ExportPanel names each file once. The panels share
`canvas::panel`: editing, pair, caption, heading and color_well.
ToolLayer lies over an InfiniteCanvas and carries its tools. Select
takes the topmost shape a press reaches, Shift adds or drops one, a
drag moves the selection and snaps its nearest edge or middle to
another shape's within reach, a handle resizes it, Shift keeping a
corner's shape, and a drag on empty space draws a SelectionBox that
takes what lies wholly inside. The shape tools draw by a drag toward
any corner, Shift keeping them square; the pen adds a point per press
and a double press ends the path; text drops a line where pressed; the
brush strokes a path its width. A drag may end in the layer or out of
it; each gesture ends once and asks the owner. SelectionBox,
TransformHandles and SnapIndicator draw the marks.
ToolPalette picks a tool from icons named in tips; BrushSettings sets a
brush's width and hue; HistoryPanel lists the steps done, the undone
ones quiet, and takes the drawing to a step on Enter or a double press.
The model changes: lines and arrows end at a named corner, so they run
either way, and paths carry their width. Three Lucide icons: hexagon,
slash and move-up-right.
