feat(tui): complete TUI redesign per blueprint by avoidwork · Pull Request #283 · avoidwork/madz

avoidwork · 2026-06-16T13:11:56Z

Description

Complete TUI redesign based on docs/TUI.md blueprint. Restructures the TUI to align with its four core tenets: input is primary, output is a log, silence is the default, and batteries are included.

Changes Summary

State Management

Consolidate 8+ useState calls into single useReducer with TUIState interface
Add typed action types (TUIAction) for all state mutations
Extract derived state into selector functions

Streaming

Extract streaming logic into useStreaming() hook
Manage AbortController lifecycle in the hook
Handle auto-continue circuit breaker in the hook

File Structure

Reorganize from flat 17-file layout to grouped structure:
- state/ — reducer, types, selectors
- hooks/ — useStreaming, useScroll, useInput, useCommand
- components/ — ConversationPanel, InputPanel, StatusBar, MessageBubble, Banner
- utils/ — commandParser, contextTokens, markdownText, format

Panel System Removal

Remove panels.js, skillsPanel.js, memoryPanel.js, settingsPanel.js
Replace with command-based output in conversation stream

Command Registry

Convert from Map-based dispatch to event-driven registry with validate, execute, help

Runtime Toggles

Add /toggle command for runtime config overrides
Add toggle indicators to status bar

Create comprehensive OpenSpec change for TUI redesign based on docs/TUI.md blueprint. Artifacts: - proposal.md: Motivation, capabilities, impact analysis - design.md: Technical decisions (useReducer, hook extraction, file reorg, panel removal) - specs/tui-state-management: useReducer consolidation requirements - specs/tui-streaming-hook: Extracted streaming hook requirements - specs/tui-command-registry: Event-driven command registry requirements - specs/tui-runtime-toggles: Runtime toggle commands requirements - specs/tui-interface: Delta spec (remove panel navigation, update command syntax) - specs/tui-scroll-view: Delta spec (add keyboard scrolling when unfocused) - tasks.md: 43 implementation tasks across 10 groups

Create state/ directory with types, reducer, and selectors. - types.js: TUIState interface, TUIAction discriminated union, initialState - reducer.js: Single reducer handling all 23 action types - selectors.js: Derived state (statusMessage, toggle indicators, streaming detection)

Create hooks/ directory with streaming, scroll, input, and command hooks. - useStreaming.js: AbortController lifecycle, event transformation, auto-continue - useScroll.js: ScrollView ref, resize handling, keyboard scroll actions - useInput.js: Keyboard routing (scroll vs history vs input focus toggle) - useCommand.js: Command parsing and dispatch to registry

Create utils/commandParser.js with event-driven command registry pattern. - Commands registered as objects with validate, execute, help properties - All default commands: /quit, /clear, /new, /help, /config, /provider, /schedule, /gc - Skill execution fallback for unrecognized commands - Unknown command handling with helpful message

Create utils/format.js with toggle logic and register /toggle command. - format.js: toggleSetting, formatToggles, handleToggleCommand - /toggle command: no args shows all, with arg toggles - /skills and /memory commands: output to conversation stream - Toggle defaults: autoScroll, timestamps, commandEcho, cursorBreathe, debugOutput

Major TUI architecture refactor: - app.js: Complete rewrite using useReducer, useStreaming, useScroll, useInput, useCommand hooks - components/: ConversationPanel, InputPanel, StatusBar, Banner (extracted from flat layout) - panels/: OnboardingPanel (extracted) - utils/: markdownText.js, contextTokens.js (extracted) - index.js: Updated exports for new structure - StatusBar: Added toggle indicators support - InputPanel: Simplified (cursor managed by useCursor in app.js) - Removed panel navigation (Tab key now toggles input focus only)

Per blueprint: 'No panels, no tabs, no switching.' Deleted: - panels.js (panel navigation) - skillsPanel.js - memoryPanel.js - settingsPanel.js - hooks.js (panel state) - components.js (old re-exports) Added /skills and /memory commands that output to conversation stream instead.

Remove superseded flat files: - banner.js, commandParser.js, contextTokens.js - conversationPanel.js, inputPanel.js, markdownText.js - messages.js, onboardingPanel.js, statusBar.js All functionality now lives in the new directory structure: - state/ (reducer, types, selectors) - hooks/ (useStreaming, useScroll, useInput, useCommand) - components/ (ConversationPanel, InputPanel, StatusBar, Banner, messages) - panels/ (OnboardingPanel) - utils/ (commandParser, contextTokens, markdownText, format)

Unit tests: - reducer.test.js: All 23 action types, edge cases, concurrent updates - commandParser.test.js: Command validation, execution, unknown commands, skill fallback - contextTokens.test.js: tiktoken calculation, character-count fallback - markdownText.test.js: Markdown rendering, edge cases - useStreaming.test.js: Event transformation, auto-continue, abort handling Integration tests: - full-flow.test.js: User input → streaming → message display → command execution All tests use node:test (built-in, no dependencies).

- tui.test.js: CommandParser→CommandRegistry, update all imports - contextTokens.test.js: utils/contextTokens.js - conversationPanel.test.js: components/ConversationPanel.js - statusBar.test.js: components/StatusBar.js - gc.test.js: CommandRegistry, utils/commandParser.js - Remove panel navigation tests (panels removed)

- Update all TUI test imports for new file structure - Remove panel navigation tests (panels removed) - Fix syntax errors from incomplete panel test removal - Note: tui.test.js has expected failures due to CommandParser→CommandRegistry behavior changes

Lint fixes: - Remove unused imports (initialState, getToggleIndicators, hasStreamingMessage, setTodoStreamingCallback, useMemo, mock) - Prefix unused parameters with _ (_dispatch, _onExit, _args, ctx) Test fixes: - Fix CommandRegistry execute functions to be synchronous (was async) - Fix provider command validate to allow /provider without args - Fix help command to accept ctx parameter - Fix config command message when _setConfigValue not provided - Fix InputPanel test props (text→inputText, char→cursorChar) - Fix contextTokens.test.js (remove unused originalTiktoken, simplify fallback test) - Fix useStreaming.test.js (remove unused mock import) - Fix commandParser.test.js (prefix unused args with _) - Fix ConversationPanel.js imports (messages.js, markdownText.js) Result: 1129/1129 tests passing ✓
