[dependabot]

Bumps @earendil-works/pi-tui from 0.81.1 to 0.84.1.

Release notes

Sourced from @​earendil-works/pi-tui's releases.

v0.84.1

New Features

• Qwen Token Plan Individual — Use the built-in provider for models documented for Individual subscriptions. See API Keys.
• Authentication readiness checks — Use pi auth check to verify provider or model credentials, optionally emitting the resolved credential.
• Improved fullscreen interaction — Select words and paragraphs with multiple clicks and configure half-page transcript scrolling. See TUI Fullscreen Viewport.
• Terminating blocked tool calls — Extension tool_call handlers can stop all-terminating batches without another model call. See Tool Events.

Added

• Added Qwen Token Plan Individual as a built-in provider with its documented subscription model catalog and the shared international QWEN_TOKEN_PLAN_API_KEY. See API Keys (#7659 by @​arasovic).
• Added pi auth check provider/model auth preflight with optional credential output (#7152).
• Added terminate support to blocked extension tool_call events so all-terminating batches can skip the automatic follow-up model call. See Tool Events (#7715 by @​muyiyr).
• Added inherited double-click word and whitespace selection, granularity-aware drag selection, and triple-click paragraph selection in fullscreen mode (#7725, #7733 by @​volsa).
• Added inherited unbound half-page transcript scrolling actions for fullscreen mode. See TUI Fullscreen Viewport (#7735).

Changed

• Softened the bash tool's PI_* environment guideline in an attempt to reduce unnecessary inspection commands (#7128).
• Reduced worst-case automatic terminal theme detection delay from 200 ms to 100 ms by probing color-scheme and background support concurrently.

Fixed

• Fixed Bun standalone binaries crashing on startup when the cwd contains a bunfig.toml with preload by compiling with --no-compile-autoload-bunfig (#7685 by @​geril07).
• Fixed extension TUI method wrappers recursing indefinitely when delegating to the original method (#7731).
• Fixed right-click not pasting clipboard text in fullscreen mode on Windows.
• Fixed inherited Agent.reset() clearing transcript and runtime state during active runs; it now rejects until the agent is idle (#7717 by @​wesleyzhangwq).
• Fixed inherited LaTeX relation, multiplication, and named-operator spacing, and matrix composition with stacked fractions, operator limits, and adjacent matrices.
• Reduced inherited fullscreen mouse event volume under tmux, Zellij, and GNU Screen by using button-motion tracking instead of all-motion tracking.

v0.84.0

New Features

• Fullscreen TUI mode — Switch between regular and fullscreen modes at runtime, with a sticky editor and footer, independently scrollable transcript, and draggable scrollbars. See UI & Display.
• Mermaid and LaTeX rendering — Render Mermaid diagrams and terminal-friendly Unicode math in interactive transcripts. See Markdown settings and TUI Markdown.
• Per-directory context overrides — Use AGENTS.override.md to replace context files for a specific directory. See Context Files.
• Advanced custom model sampling — Configure arbitrary OpenAI-compatible samplingParams and opt-in vLLM thinking_token_budget values. See Sampling Parameters.
• Baseten provider — Use built-in Baseten authentication and model support. See API Keys.

Breaking Changes

• Renamed the inherited pi-ai ModelsStreamTransforms interface to ModelsRequestTransforms because its header transformation now applies to all authenticated provider requests.

• Changed JSON and RPC message_update events to emit only assistantMessageEvent deltas, removing the cumulative message and assistantMessageEvent.partial fields that caused quadratic output growth. Clients that need partial messages must assemble deltas between message_start and message_end; the latter remains authoritative (#7290).

• ModelRegistry.getApiKeyAndHeaders() now returns ProviderHeaders with string | null values and preserves null header-deletion markers. Extensions that inspect returned headers must handle null; extensions forwarding them to pi-ai streams should pass them through unchanged. This prevents placeholder OpenAI credentials from being sent through Cloudflare AI Gateway (#7030).

• Changed ModelRegistry.refresh() to accept ModelsRefreshOptions and return ModelsRefreshResult instead of discarding cancellation and provider errors.

• Changed ModelRuntime.setRuntimeApiKey() to accept auth cancellation options rather than catalog refresh options. Call refresh({ providers: [providerId], signal }) separately when remote freshness is required.

• Required config-form extension OAuth refreshToken(credentials, signal) callbacks to accept and honor a concrete abort signal.

• Replaced dynamic provider refresh context store access with the read-only context.stored snapshot and generation-checked context.publish() transaction.

  Providers built with createProvider({ fetchModels }): no catalog-publication migration is required. Before and after, return the fetched models and register the resulting provider; createProvider() owns restoration, persistence, and in-memory publication.

Changelog

Sourced from @​earendil-works/pi-tui's changelog.

[0.84.1] - 2026-08-07

Added

• Added unbound half-page transcript scrolling actions, tui.altScreen.halfPageUp and tui.altScreen.halfPageDown, for fullscreen TUI keybindings (#7735).
• Added double-click word and whitespace selection, granularity-aware drag selection, and triple-click paragraph selection in the fullscreen TUI (#7725, #7733 by @​volsa).
• Added an optional right-click paste handler to the alternate-screen TUI, currently enabled on Windows.

Fixed

• Fixed LaTeX relation, multiplication, and named-operator spacing, and correctly composed matrices with stacked fractions, operator limits, and adjacent matrices.
• Reduced fullscreen mouse event volume under tmux, Zellij, and GNU Screen by using button-motion tracking instead of all-motion tracking.

[0.84.0] - 2026-08-06

Added

• Added terminal-friendly Unicode rendering for LaTeX expressions in Markdown, including inline and display math, fractions, scripts, common symbols, aligned equations, cases, and matrices.
• Added the shared TuiMode type and mode discriminants to the main-screen and alternate-screen TUI renderers.
• Added TUI lifecycle and render-state handoff APIs for replacing renderers without replaying main-screen content.
• Exported the bundled Marked parser and token types.
• Added width-aware source transforms to the Markdown component.
• Added interface-compatible main-screen and alternate-screen TUI renderers with application-owned scrolling (#7304).
• Added alternate-screen VStack, HStack, and nested ScrollView layouts with constrained sizing, sticky regions, and pointer-targeted scrolling.
• Added edge auto-scrolling for alternate-screen drag selection across off-screen scroll-view content.
• Added proportional scrollbars with mouse dragging, Home/End document navigation, transient auto mode, and an always mode that reserves the rightmost column; scrollbar modes can be changed at runtime.
• Added page scrolling and OSC 133 semantic prompt navigation to the alternate-screen viewport.
• Added configurable previous/next prompt history actions for navigation independent of vertical cursor movement.
• Added stacked transient notifications to the alternate-screen renderer (#7361).

Changed

• Reduced the default alternate-screen mouse wheel step from three lines to one for finer scrolling.

Fixed

• Fixed Windows Shift+Enter detection by extending the native Win32 helper to report modifier key state.
• Fixed the npm package omitting the source and build script needed to rebuild the Windows native addon.
• Fixed the npm package omitting the source and build script needed to rebuild the Darwin native addon.
• Fixed Windows console truecolor detection when Windows Terminal does not provide WT_SESSION to child shells.
• Fixed terminal width accounting for Indic conjunct grapheme clusters (#6987 by @​petrroll).
• Fixed phantom alternate-screen text selection from unmatched mouse events when changing terminal pane focus.
• Fixed spaces in searchable settings queries changing the selected value instead of filtering multi-word labels.
• Fixed alternate-screen Kitty images crossing vertical layout clip boundaries and overlapping sticky regions while scrolling.
• Fixed alternate-screen redraws retransmitting Kitty image data when placements move or recently offscreen images return, dropping adjacent row content when reusing placements, rendering fixed-basis scroll content twice per frame, and scanning clipped transcript rows while painting.
• Fixed fullscreen transcript navigation leaving no editor-accessible Home, End, PageUp, or PageDown variants by adding Ctrl-modified editor bindings (#7574).
• Fixed keyboard input rendering latency on Windows by letting input preempt the throttled render timer.
• Fixed nested stack layouts ignoring child minimum sizes.
• Fixed batched terminal color-scheme reports being parsed as one malformed response (#7550).
• Fixed terminal progress clearing to emit the complete OSC 9;4 sequence (#7581).
