StickerPicker shows stickers a pack at a time, chosen above with a
segmented control; a search spans every pack and keeps the stickers
whose names hold it. Arrows move, Enter or a press picks. It reuses the
glyph grid, now forms::picks, which takes its columns and cell size and
titles from the host, so emoji, icons and stickers share one searchable
grid; forms::glyphs keeps the emoji and icon pickers.
GifPicker packs host GIFs in two columns, each moving, under a search
it owns; the host hears the trimmed words only when they change, and
categories fill the search while it is empty. Waiting, it shows tiles
in GIF shapes; finding nothing, it says so. Each GIF is a Tab stop that
a press, Enter or Space picks.
The share toggle now shows its state, as the microphone and camera do.
The gallery ships line-drawn stickers and small GIFs made from its own
pictures.
CallControls holds the microphone, camera and a shared screen as
toggles, then Leave. ParticipantTile shows a camera's frame from the
host or the person's initials, their name with a mark when muted, and a
ring while they speak. VideoCallGrid lays tiles in even rows as far as
they fit across its measured width; a short last row centers at the
full rows' width. ScreenShareView names who presents and offers Stop
presenting for your own share, the call's tiles beside or below.
VoiceCallBar tells where a call is, how long it has run and who is in
it, with the microphone and Leave. IncomingCallDialog rings with the
caller's picture; Accept or Decline answers each ring once, and Escape
declines. HuddleIndicator rings while a huddle is live; a press joins.
The recorder's device toggle and the camera's name chip now have one
home in media. People: member names sort whatever their case, a
status's words save trimmed, and a profile card's local time ticks.
MemberList sets members online and offline by name, each group a list
under its count. A press or an arrow chooses one; Enter or a double
press acts on them; offline members go quiet. UserProfileCard shows a
person's picture with presence, name and standing, title, status, the
time in their zone, and Message and Call, each only with a handler.
OnlineStatus draws a presence's dot and word; Presence now names itself
and gives its color, in data_display, its one home.
StatusSetter holds a draft seeded from the owner's status: an emoji
from a picker field, words in its own text field, and when they clear.
Suggestions fill all three; Save hands the status over and Clear status
removes it. The emoji field reuses the date pickers' field, whose
trigger ignores the Enter release after a pick.
ChatMessage sets a message under its author's picture, name and clock
time. The next by the same author within five minutes, on the same day,
joins the run: only its words, the time in the gutter on hover.
UnreadDivider marks where unread messages start. MessageThread tells who
replied, how many and when the last came; with a handler it opens on a
press, Enter or Space. ThreadPanel holds the first message, a rule
counting the replies, the replies and a composer, its body scrolling.
ReadReceipt says sending, sent, delivered or read, and who saw it in a
group. MessageReactions and TypingIndicator point to collab and motion.
gpui recolors nothing on hover: text takes its color at layout. The
gutter time rests invisible and turns visible through a group hover.
ChannelList sets chats down in sections, each a list: a press, an arrow
or Enter opens one, and the open chat is lit. A title names one section,
and a section holds a chat. ChannelItem shows a hash or a lock, its
unread count, a pin when pinned, and goes quiet when muted.
DirectMessageItem shows a person's initials with their presence. Unread
names stand out through ListItem's new strong; muted channels and
offline people go quiet through its quiet. ChannelHeader holds the name
and topic beside members, pins and a call, wrapping by the header rule.
PinnedMessages lists pins newest first; a press, an arrow or Enter opens
one, and Unpin lets one go. With none it shows a line and takes no Tab
stop.
A file on its way is a Transfer with a state: waiting, moving at a rate,
paused, done or failed with a reason. One row draws it for the queue and
the downloads: its icon, its way, a bar while it moves or waits paused, a
status with the time left, and only the actions its state allows.
TransferQueue counts what moves and waits. DownloadManager keeps the
finished below under Clear, opening on a press and showing their folder.
FileOperationProgress tells a copy or move with its bar, time left and
current file, its header wrapping by the header rule; a failure speaks in
the danger tone. StorageUsage points to data_display's UsageBar.
FilePreview shows a file large: its picture in the host's shape, the first
lines of its text, or its kind's icon, over its name, kind, size and
change; the gallery opens it on Space as a quick look. RecentFiles lists
files newest first under a header a day, a list a day. FileSearch sits
over a field the host owns and lists what the host found with its folder.
DuplicateFinder marks copies to remove and keeps the last of each group,
its mark shut, with the bytes the marks free beside Remove. ArchiveViewer
draws an archive's entries as a tree with sizes and savings, from paths
gathered by the folder builder the file tree now shares. A checkbox's
label wraps inside its box instead of running past it. Favorites and the
hex viewer point to documents and debug.
FileExplorer shows the folder at the end of a path three ways: the
directory listing, a grid of tiles, or a column per folder along the
path with the next folder lit. Its name, its count and a switch of views
sit above one path bar that climbs. A folder opens in place; a file goes
to the host, which lists each folder it goes to. A pick in an earlier
column closes the columns past it, and a new deepest column scrolls into
view. The directory listing takes its pick from its owner and reports
it, so the pick carries across views; its path bar and its first order
are shared. The gallery walks a small file system and shows the tree,
the context menu, renaming in place and a drop zone in use.
gpui's line_clamp wraps once and lays the rest of a long name on the
second line, which a centered tile then clipped at both ends. A tile's
name is now one line, cut in the middle so the front and the extension
stay. MiddleEllipsis draws like Ellipsis: in the text style around it,
sized by its text, so a short name centers; the two share one cutter.
The crate had two maps from a file's name to its icon, in chat and in the
file tree, and they disagreed. One map now lives in primitives, over the
Lucide file-* icons, and chat, agent, the file tree and the directory
listing use it. FileIcon draws it for a file or a folder. FileItem is a
file's row, a ListItem with its size and when it changed. FileList is the
directory listing. FileGrid lays tiles in the order given, with a cursor
seeded from the owner's pick: arrows by tile and by row, Home, End, Enter
and a double press to open. The count of what fits a width has one home,
layout's columns_for, and fit builds on it.
ScreenRecorderControls holds a recording in one pill: Record, then a live
dot and the time it has run beside pause or resume and stop, with mic and
camera toggles. CameraPreview shows host frames in the camera's shape, or
the camera off. MicLevelMeter lights segments up to the level, amber and
red near the top, with tones shared from data_display. DeviceSelector
picks a microphone, camera or speaker through Select, which may now be
empty while shut. ModelViewer shows the host's frame for an orbit that a
drag, the arrows, Command-scroll, + and - and a reset move; the orbit is
seeded from the host so fast drags add up. The gallery draws a stone
torus per orbit and frees each replaced frame.
AudioPlayer sets a song's cover, title and artist over a scrubber with
the time played and left, the transport and the volume. AudioWaveform
draws peaks gathered to the bars that fit, dark as far as it has played,
and seeks by press, drag and keys, with the time tip the scrubber shares.
AudioSpectrum shows levels by pitch. VolumeControl mutes from its speaker,
and moving its slider while muted unmutes. PlaybackSpeedControl picks from
a menu. MediaControls holds shuffle, back, play, forward and repeat.
Playlist builds on SelectableList: the song under way is lit with moving
bars, and Enter or a double press plays another.
The video player's bar now rests while the stage itself holds focus, a
key it takes wakes the bar, and a press on a resting bar only wakes it.
Scrubber shows what has loaded, what has played and its chapters, names
the time under the pointer, seeks by press and gpui's drag, and steps by
the slider's keys; over_media lights it for a dark layer. VideoPlayer
shows the host's frame in its shape with a caption and a control bar over
it: the scrubber, play, the time, speed, captions, picture in picture and
full screen, each only with its handler; the bar rests after a still
pointer while it plays, on one wake from the executor's timer. Keys:
Space and K, J and L, the arrows, C and F. VideoThumbnailStrip lays frames
along the length under a playhead with a trim whose handles drag and whose
ends I and O set. SubtitleEditor edits cues in place: times as mm:ss.mmm,
kept in order, a time that does not read kept out with the reason shown.
InlineEdit is a Tab stop with the ring; it hands focus back after Enter or
Escape and keeps its text on Enter's release. overlays::media_button is
shared by the lightbox and the player's bar.
ImageCropper crops a picture by a box in shares of it: a press holds a
corner, a side or the body (crop::grip_at), a drag through gpui's drag
moves them (crop::dragged), kept inside the picture with a least side;
with an aspect only the corners size it and the box keeps its shape; the
arrows move it. The picture sits inset by half a handle, the focus border
outside it, so handles on its edge stay whole and it keeps its shape.
ImageUpload (T06e) takes pictures only, from a drop or the dialog
(forms::taken, DropZone::kinds), decodes the file for its shape, and with
no crop yet reports the largest centered box of its aspect once. The
annotator draws boxes, arrows, lines and numbered pins in chart colors
through forms::pen; Select chooses a mark, Delete removes it, and Cmd-Z
and Shift-Cmd-Z undo and redo through forms::History. theme.media() holds
their sizes.
A new chapter, src/media. ImageViewer fits a picture to its stage and
zooms by the document steps, by keys, buttons and Cmd-scroll about the
pointer; a drag through gpui's drag, a scroll or the arrows pan it once it
overhangs; R turns it a quarter at a time. gpui paints pictures without a
transform, so media::turn turns the decoded frames off the main thread,
an asset keyed by the picture and the turn; `image` 0.25, which gpui
already decodes with, is now a dependency. ImageThumbnail shows a picture
in its own shape with a corner label and a ring when chosen, and is a Tab
stop only with a handler. Lightbox / Gallery Viewer points to
overlays::Lightbox, which the gallery opens from the thumbnails.
T26 splits into T26a–e. AGENTS.md: the drag rule says drags that pan,
turn or slide go through gpui's drag; pictures turn by their pixels.
DatasetViewer is tables::DataTable with row detail; the gallery pages
through a dataset and opens a sample whole. EmbeddingVisualizer scatters
points by group, flat or turned in three dimensions: lens.rs holds the
projection, where a turned view keeps the unit ball's scale and fits any
point past it at every turn. A drag or the arrow keys spin it, the
pointer names a point, and the legend hides a group. PromptPlayground
gives each {name} of a template a field, marks the blanks, and runs once
every value is in. PromptDiff shows word changes inline, a space parting
a word taken out from the word put in; PromptVersionHistory lists
versions to choose from and restore.
ChartLegend entries that toggle are Tab stops with the focus ring. Each
capture pass starts its page fresh, so dark runs the script from the same
start as light.
ModelCard sets a model's maker, what it does, its facts and tags, and
Use unless it is in use. ModelDownloadManager lists downloads with how
much of how much, speed and time left, and Pause, Resume, Cancel,
Retry and Delete by state. ModelStatus marks a model idle, loading,
loaded with its GPU memory, or failed. HardwareMonitor sets a meter per
part beside its history. FineTuneJobCard shows a job's phase, its
epochs and its loss on training and held-out data.
AGENTS.md: after each item, cargo clean -p ely-gpui-component too;
old builds of the crate had filled the disk. The reveal rule names
layout::bring_into_view.
AudioGenerationPlayer shows a generated sound's prompt, model and
length, a bar while it is made, then chat::AudioMessage to play it;
Regenerate and Download wait for it. TTSVoicePicker lists voices with a
sample to play, the chosen one washed with a check, tags dropping below
when narrow. VideoGenerationTimeline lays shots along their time under
a ruler, with posters, placeholders, a playhead and Extend.
AudioMessage's waveform is one Tab stop where Left and Right seek, and
it gives way at 280px. debug::ruler serves the timeline's ruler. A mask
shown to read no longer follows the pointer.
InpaintCanvas is a Tab stop with the focus ring only when on_brush
serves its keys, and takes the pen, the crosshair and the ring only
with on_stroke. new() asserts each stroke's radius within REACH and
its points on the picture. The settled strokes' cells stay cached, so
a drag paints only the stroke under the pen over a copy. The canvas
keeps square corners, so the wash fits the picture. The gallery drags
with moves.
InpaintCanvas lays a mask over a picture: brush strokes in shares of
the picture, rastered into a 320-column grid where a later stroke wins
and an erasing one clears, painted as merged rectangles snapped to
device pixels. A ring follows the pointer at the brush's size; [ and ]
size the brush and X swaps it when focused. MaskBrush sets paint or
erase and the size, with Undo and Clear waiting for a stroke.
Pointer strokes move to forms::pen, which SignaturePad and the canvas
share.
GenerationQueue shows each job's picture or where it stands, its
prompt and its progress, with Cancel, Retry and Remove as its state
allows; new rows fold in. GenerationGrid lays a run's results out in
their shape: breathing while they come, the picture once done, why one
failed with Retry. VariationPicker shows the chosen variation large
over thumbnails and ways on from it. ABCompareView sets two to four
models' answers side by side, blind until a verdict. ImageCompare
points to data_display::BeforeAfter.
primitives::framed and checked_ratio now serve previews and generative
alike. AGENTS.md records that gpui reads a &str picture as a web
address, and that grid rows overgrow tiles that keep a ratio.
PromptEnhancer offers a fuller prompt with the words it adds washed,
split at punctuation; Use this takes it into the field, Keep mine
lets it go. StylePresetPicker and AspectRatioPicker are rows of Tab
stops, the chosen one in accent; a ratio chip draws its shape.
SeedInput keeps digits up to u32::MAX and rolls one with a die.
NegativePromptInput and ImageGenerationPanel point to forms::TagInput
and forms::Form. theme.generative() holds the chapter's sizes. The
gallery's preset pictures are the atrium photo in five styles.
HumanInputRequest asks a question with answers to pick and a line to
write one; CostBreakdown totals a session and splits it by part.
InterruptButton, TokenUsageChart, TraceViewer and EvalResultTable
point to chat::stop_button, a stacked BarChart, TimelineProfiler and
DataTable.
UsageBar shows amounts as its owner writes them. MemoryPanel and
HumanInputRequest share agent::line::send_line; the chapter's bool
callbacks take forms::OnFlag.
DataTable scrolls columns wider than its box sideways, pinned or not,
and leaves a plain wheel to the page; sortable headers are Tab stops.
TimelineProfiler fits its ruler to its lane, its spans are Tab stops,
and a picked span takes accent.
- SandboxStatus: a dot and a word (a ring while it starts or works), what it
uses of what it has as meters, and how long it has run; the header wraps
- McpServerList over lists::ListItem: a dot per state, what it runs or why it
failed, its tools once connected, and a switch
- ToolRegistry: tools grouped by source, found by every word of the owner's
query, each Allow, Ask or Deny; rows wrap at 280px
- MemoryPanel: a line to keep a memory, Enter or Remember, blank words kept
out; each memory with its source, when, and Forget
- CheckpointList over data_display::Timeline, newest first, the current point
marked, Rewind on the rest
- gallery: every control wired to state
- BrowserPreview: the address with a lock and a spinner while it loads, the
host's frame shown, and the frames so far along the foot as Tab stops;
ScreenshotStream is that strip
- ComputerUseViewer: the host's frame, a ring where the agent points that
rings again at each new point, and what it does there
- LivePreview: the host's page under its address, with reload
- ArtifactPanel: title, versions through chat::BranchNavigator, Preview and
Source when it has both, copy and download; it fails loud with neither
- gallery: frames cut from the gallery's own pages; one asset! macro in
main.rs replaces three copies
- FileChangeCard's header wraps: the path keeps label_width, counts and
verdict drop below as one group; MultiFileDiffReview's header wraps its
counts and its all-buttons inside the box, parted by justify_between
- git::DiffViewer's fold rows are Tab stops with a focus ring when the
owner opens folds; every row keeps a transparent border so heights match;
an inert fold no longer shows a pointer
- tests: a_narrow_review_wraps_its_rows_inside_its_box,
git::a_fold_opens_from_the_keyboard; the gallery adds a 280px review
- AGENTS: taffy drops gaps beside an auto margin; wrapping headers
- FileChangeCard: a proposed change to one file, its path and counts,
Reject and Accept in a slot that keeps presses off the header; opened,
the diff through a headless git::DiffViewer with its folds opening
- MultiFileDiffReview: every file at once, the total counts, how many are
reviewed, Reject all and Accept all; verdicts as collab::Decision
- git::DiffViewer gains headless, leaving the file's header to its owner
- CommandExecutionCard is terminal::CommandBlock
- gallery: three proposed files and a command's block
- AgentStepList: an agent's steps down a data_display::Timeline rail,
marked by chat::step_mark, with detail and time
- AgentPlan: items waiting, at work or done, with a count; done items go
quiet and struck through
- chat::step_mark reads motion::changes: a check or cross that arrives pops
in, still on first paint
- AgentStatus: a pill for planning, working, waiting, done or failed
- AgentProgress: the step at work, done of total, the time so far and a
bar split by step; progress past its total fails loud
- SubAgentTree is lists::Tree with each agent's state as its note
- gallery: a plan the button advances, steps, statuses and a tree
- overlays::Dialog caps its card at the window, a title bar's height clear
at each end, and scrolls its body while heading and actions stay; the
fullscreen body scrolls too; test a_tall_dialog_keeps_its_actions_in_the_window
- ToolCallCard's tool name gives way with an Ellipsis, so time and chevron
stay in a narrow column; the gallery shows one at 280px
- the Agent script shuts the card it opened, so each theme's shot opens it
- AGENTS: dialogs fit the window
- ToolCallCard: a step mark, the tool in mono, what it touched and how long
it took; a press opens its arguments and result as code, an error in red
- ToolCallGroup folds several calls under one line
- ToolApprovalDialog over overlays::Dialog: Deny or Run, one answer; Escape,
the scrim and the close deny
- PermissionPrompt: deny, always allow or allow once, in place
- chat::StepState gains Failed; chat::step_mark draws a step's mark for
search steps and tool calls alike
- typography::format::took reads ms, seconds or minutes
- gallery: an Agent page with calls in each state, a group, the dialog and
the prompt
- WelcomeScreen: a greeting for the hour over the owner's composer,
starters and cards, centered while it fits and scrolled from its top
when it does not
- SuggestionChips, FollowUpSuggestions and CapabilityCards: each press asks
the owner; rows and cards are Tab stops
- PromptLibrary is documents::TemplatePicker over saved prompts
- gallery: starters and cards fill the welcome composer, a saved prompt
fills it too, send clears it with a toast, a follow-up asks its question
- the conversation list reads the zone through format::system_zone, which
fails loud; the gallery expects the system zone
- Combobox opens with its cursor on its value, MultiSelect on the first
row ticked; tests for all three lists open r25 of thirty in view
- AGENTS: the zone rule; lists open on their choice
- ConversationList: pinned first, then by day, newest first; a query keeps
the titles that hold every word
- ConversationItem: a Tab stop when there is something to do; its menu of
rename, pin and delete shows on hover, while open, or while the row holds
focus; a press on the menu leaves the row shut
- new_chat_button, ProjectList, ProjectKnowledgePanel with a capacity meter
- SharedConversationView: who shared it and when, and a way to carry it on
- ConversationExport: format and thinking in a Dialog, Cancel or Export
- icons: square-pen, corner-down-right
- gallery: conversations with rename, pin and delete; projects; a shared
conversation; export with a toast
- suggestions: arrows step past disabled rows and scroll the cursor into view;
the cursor starts on an enabled row; Enter refuses a disabled one
- active_trigger takes the query's word test: one word for mentions, any
non-space for the composer, so a file name keeps its dot
- DragDropOverlay takes the drop itself, which gives it the hitbox gpui needs
to style a drag-over
- ParameterPanel shows the places of the step, value and both ends
- gallery: the prompt menu fills the draft; Reset restores the system prompt
- AGENTS: drag-over styles need a hitbox; debug_bounds never clear
- PromptInput: attachments and context above the field, the owner's tools and
send below; Enter sends, Shift-Enter breaks the line; / offers commands and
@ offers context over forms::Suggestions; files dropped on it attach behind a
drop veil
- AttachmentButton, AttachmentChip with thumbnails and uploads, ContextChips
- VoiceInputButton and VoiceWaveform with a red dot and the time
- ParameterPanel, SystemPromptEditor, TokenCounter, CostEstimator
- forms: a Newline action on Shift-Enter keeps one-line fields to one line;
replace_trigger moves beside Suggestions; choose and dropped shared
- gallery: composer, pickers and tuning
- the gallery binds its passage's range before the vec, as clippy asks
- AGENTS: anything pressable is a Tab stop; text in a row gives way to fixed parts

- the sources row and a passage's header shrink with an ellipsis, keeping the
count, chevron and score in view
- chat tests move into a folder, citations in their own file
- gallery: a narrow column of citations
- CitationBadge: a numbered pill after a claim, its source on hover, a press
opens it; a Tab stop

newest, counting arrivals while away; a way back down; day separators
- streaming text and markdown reveal toward the text as it grows, with a caret;
a blinking cursor before the first words
- CodeBlock with language, copy, run, apply, download and folding;
MarkdownRenderer::code lets messages draw fences with it

continue
- errors with retry, a rate limit counting down, feedback, thinking blocks

- gallery: the Collaboration page with scripted states
- a page centers only while it fits the view; a wider one starts in reach
- the reveal runs after the pages' prepaint and keys on the hit itself, so a
new hit at the same index and a hit current from the first frame come into view
- the chapter list scrolls
- zen takes focus when turned on from outside, so Escape leaves it, and hands
focus back
- the gallery keeps a page's due date and tags
- DocumentViewer: pages the app drew on a desk, the page under the view's middle
counted, zoom steps and fit, thumbnails, notes pinned where a press lands, and
the owner's FindWidget over the pages, hits lit and the current one revealed
