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::cpu asserts its share lies in 0..=1 and hands it to
Meter unclamped. ToolRegistry gathers kept tools by source through
grouped(), tested for first-seen order and repeated sources.
- 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 marks the shown frame with accent; the focus color stays
the focus ring's
- BrowserPreview and ComputerUseViewer take the host's ratio, 16:10 unless
set, so frames keep their shape and a pointer's share lands on the picture;
test a_screen_takes_its_pictures_shape
- TASKS: the review moves to a Claude Fable 5.1 max session after codex ran
out of quota; round 3 fixed after the cap, no fourth review
- AGENTS: focus and choice colors part; host pictures keep their shape
- BrowserPreview keeps a ScrollHandle for its strip and a tracked focus
handle per thumbnail; the focused thumbnail scrolls into view once, through
forms::options::reveal and the canvas now shared as revealer
- Popup draws its reveal through the same revealer
- test tab_brings_a_hidden_frame_into_view
- BrowserPreview's frame strip scrolls sideways, so every frame stays in
reach in a narrow card
- ArtifactPanel's header wraps: the title keeps label_width, the controls
ride in one group that wraps inside the box
- tests: a_narrow_strip_scrolls_to_its_last_frame,
a_narrow_panel_wraps_its_header
- AGENTS: everything works at 280px
- 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
- AgentProgress splits its bar only for two steps or more; a task of one
step draws a plain bar
- test a_task_of_one_step_draws_before_and_after renders 0 of 1 and 1 of 1
- 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
- a dialog's body scroll box holds one inner column, so the body keeps
its height and scrolls instead of shrinking to the capped card
- test a_tall_dialog_body_keeps_its_height_and_scrolls: 2000px stays
2000px and a 300px wheel moves it 300px
- 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
- Select, Combobox and MultiSelect opened a long list at its top, the
choice out of view: gpui skips a scroll asked before the list's first
frame. Picker and Suggestions share forms::options::reveal, which Popup
runs from a canvas inside the list
- test: a_long_list_opens_with_its_choice_in_view
- AGENTS: the scroll rule names the reveal
- a trigger opens only its word, so a path keeps its slashes in the query
- suggestions reveal the cursor once the list has its bounds: Popup takes a
row to reveal, and a canvas inside the list asks for it and one more frame
- 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
- source cards and web results with a handler are Tab stops with focus rings
- 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
- SourceCard and SourceList: the sources folded under their count and sites,
each a card numbered as cited; the fold opens from the keyboard
- SearchProgress: steps waiting, working and done
- WebResultCard and DocumentChunkPreview with matched words washed
- gallery: citation and sources states
- your messages shrink within their column and wrap there
- pictures, grids and video take their own shape up to their column's width;
files, voice notes and link cards stay inside it
- a finished stream shows whole
- avatar pictures load from web addresses too
- the list drops its way down once everything fits again
- the reasoning toggle is a Tab stop with a focus ring
- a link's thumbnail keeps its corners
- gallery: a narrow column of media
- messages: yours in a quiet bubble, the assistant's as prose beside its mark,
system notes, errors; avatars, headers with model and time, footers
- MessageList over gpui's bottom-aligned list: drawn near the view, held at the
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
- pictures, grids, files, voice notes, video over host frames, link previews
- quotes, actions, an editor that takes focus, versions, regenerate, stop and
continue
- errors with retry, a rate limit counting down, feedback, thinking blocks
- gallery: the AI Chat page with scripted states
- a remote cursor shows only while its caret sits inside the field, sideways too
- presence avatars keep a transparent border for the focus ring
- the access list shows each role, as words when it cannot change
- status dots take the theme's size
- peer and member pictures load from files and web addresses alike
- presence: avatars ringed in each peer's color with where they are, press to
follow; a breathing live dot; follow mode frames the view and stops on Escape
- remote cursors and selections painted over a field from its own layout
- comment threads with replies, reactions and resolve; a marker that opens a
thread in a bubble; a sidebar of open and resolved threads
- annotations washed in their authors' colors, notes on hover
- suggestion mode: edits become suggestions word by word; track changes shows
them struck and underlined, to accept or reject
- sharing: invite by email with checked chips, roles, the access list and who
the link lets in, in one dialog
- primitives::hold_focus gives a mode its own focus, shared with ZenMode
- AvatarGroup's tuck and count shared; Avatar::ring_color; TagInput::check;
TextInput::bounds_for_range; Popover::size
- icons: smile-plus, user-plus, message-square-diff
- 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
- PageThumbnailList, EpubReader (chapters, type size, progress), PrintPreview
- MarkdownRenderer feeds TableOfContents through sections and outline
- Footnote, TooltipTerm, Glossary, ReadingProgress, ZenMode
- Backlinks, Favorites, TrashBin, PageCover, PageIcon, TemplatePicker,
VersionHistory with PageHistoryDiff
- editor::FindWidget shows the replace fold and option toggles only with handlers
- block editor tests move to documents/blocks
- icons: a-arrow-down, a-arrow-up
- gallery: reading and knowledge sections; scripted find, changes and zen
- TextInput records the selection each edit replaces, where every edit passes;
the block editor's undo goes back to it, for typing, delete, cut and paste
- TextInput's layout geometry moves to forms/text/geometry.rs
- Reviews: T21a done, fixed after the cap, no fourth review
- a field notes its selection when a key goes down, so undo of typing selects
what the typing replaced
- reading order skips table cells merged away, so Up and Down across blocks
land on cells that show
- Enter over a selection drops it and splits at its start, one undo step
- undo and redo keep where the caret was and put it back
- a format unwraps only its own markers, so italic inside bold keeps the bold
- keys into a merged table cell land on the cell that shows
- undo rebuilds a block whose kind needs other fields, so styling comes back
- tests activate their window, as focus events need
- undo bookkeeping moves to blocks/edit.rs
- markdown read with pulldown-cmark: marks for live styling, blocks, links, words
- forms::Highlight gains weight, slant and strike; measure and paint share runs
- Inter Italic embedded, so emphasis reads slanted
- forms::mention's popup and keys become Suggestions, shared with the editors
- RichTextEditor with FixedFormatToolbar, the floating toolbar, LinkEditor,
@ and : suggestions, WordCount and ReadingTime
- MarkdownEditor: visual (a pressed block opens as source), source, split
- BlockEditor: prose, lists, to-dos, quotes, callouts, toggles, code, math,
diagrams the app draws, dividers, tables that grow and merge, pictures to
resize and align, cards for video and pages, columns, synced text; slash menu,
markdown shortcuts, handles that drag and open a menu, one undo for all
- TodoItem and Checklist
- icons: heading-1..3, workflow, merge
- gallery: the Documents page with scripted states
- the hex demo's selection stops at memory's end
- a disassembly gutter fills its row, so an empty one takes a press
- a breakpoint's box keeps its press from the row
- ruler ticks keep the places their step needs
- the toolbar names each usual key for the platform; the app binds them
- tests: gutter press, box press, tick places
- DebugToolbar, BreakpointList, CallStack with folded library frames, ThreadList
- VariablesPanel and WatchPanel, colored by kind, changes washed
- HexViewer at a base address with the byte under the pointer lit on both sides
- Disassembly with source lines, registers and numbers colored, gutter breakpoints
- Flamegraph that zooms by frame, TimelineProfiler that zooms and pans by wheel
- NetworkInspector with a waterfall, a filter and a request's headers and body
- icons: redo-dot, arrow-down-to-dot, arrow-up-from-dot
- gallery: the Debug page
- regions read their lines through TextMerge's accessors; conflicts and resolve
split with similar's tokenize_lines, so a lone return ends a line everywhere
- the merged ending and line breaks know a lone return
- taking both sides separates them only when both hold text
- merge views split rows the same way
