Move line count from header to footer to avoid changing the first line
during streaming, which was triggering full screen re-renders in the
TUI's differential rendering logic.
* Add ctx.ui.setStatus(key, text) API for hooks to display status in footer
- Add setStatus to HookUIContext interface
- Implement in interactive mode (FooterComponent)
- Implement in RPC mode (fire-and-forget)
- Add no-op implementations for headless contexts
- Multiple statuses displayed on single line, sorted by key
- Supports ANSI styling (hooks handle their own colors)
* Remove setStatus from changelog for now
* Fix hook status API to follow TUI rules
- Sanitize status text: replace newlines, tabs, carriage returns with spaces
- Truncate combined status line to terminal width using truncateToWidth
- Update JSDoc to document sanitization and truncation behavior
- Remove unused createHookUIContext method
- Add missing setStatus to test mock
* Add setStatus to changelog
* Use dim ellipsis for hook status truncation for consistency with footer style

- Extract diff computation from edit.ts into shared edit-diff.ts
- ToolExecutionComponent computes and caches diff when args are complete
- Diff is visible while permission hooks block, before tool executes
- Add configurable thinkingText color for thinking blocks (defaults to muted)
- Make 'Thinking...' label italic when collapsed
- Fix Ctrl+T during streaming hiding the current message
- Track streamingMessage to properly re-render on toggle
Based on #366 by @paulbettner
- Add setEditorText() and getEditorText() to HookUIContext for prompt generator pattern
- custom() now accepts async factories for fire-and-forget work
- Add CancellableLoader component to tui package
- Add BorderedLoader component for hooks with cancel UI
- Export HookAPI, HookContext, HookFactory from main package
- Update all examples to import from packages instead of relative paths
- Update hooks.md and custom-tools.md documentation
fixes#350
- CustomAgentTool renamed to CustomTool
- ToolAPI renamed to CustomToolAPI
- ToolContext renamed to CustomToolContext
- ToolSessionEvent renamed to CustomToolSessionEvent
- Added CustomToolContext parameter to execute() and onSession()
- CustomToolFactory now returns CustomTool<any, any> for type compatibility
- dispose() replaced with onSession({ reason: 'shutdown' })
- Added wrapCustomTool() to convert CustomTool to AgentTool
- Session exposes setToolUIContext() instead of leaking internals
- Fix ToolExecutionComponent to sync with toolOutputExpanded state
- Update all custom tool examples for new API
- Add selectedBg theme color for active line highlight
- Fix filter modes:
- no-tools: default minus tool results (still hides label/custom)
- user-only: just user messages
- labeled-only: just labeled entries
- all: everything
- Update theme.md with new color tokens (50 total)
- Check response.stopReason instead of catching errors for abort detection
- Return result object from _generateBranchSummary instead of throwing
- Fix summary attachment: attach to navigation target position, not old branch
- Support root-level summaries (parentId=null) in branchWithSummary
- Remove setTimeout hack for re-showing tree selector on abort
- Show ├─ for non-last siblings, └─ for last sibling
- Show │ gutter for descendants of non-last siblings
- Properly handle multiple roots display shift
- At indent 0: stay flat unless parent branches
- At indent 1: children go to indent 2 (visual grouping)
- At indent 2+: stay flat for single-child chains
- Remove gutter/connector complexity for now
- Only indent when parent has siblings (branch point)
- gutterLevels array tracks which levels need │ vs spaces
- connector: none/branch/last for ├─/└─ display
- Tool results show formatted call info like [read: path:1-10], [bash: cmd]
- Skip assistant messages with stopReason error/aborted
- Skip assistant messages with only tool calls (no text)
- Format built-in tools like tool-execution.ts (read, write, edit, bash, grep, find, ls)
- Custom tools show truncated JSON args
- Label editing with 'l' key
- Ctrl+O cycles through filters: default -> user-only -> labeled-only -> all
- Preserve cursor position when toggling filters
- Labels shown at front of node
- Normalize tabs/newlines in content
- extractContent limited to 200 chars for performance
- truncateToWidth on all rendered lines
- Iterative flattenTree to avoid stack overflow
- Linear chain optimization (no indent for single-child chains)
- Add TreeSelectorComponent with ASCII tree visualization
- Add AgentSession.navigateTree() for switching branches
- Add session_before_tree/session_tree hook events
- Add SessionManager.resetLeaf() for navigating to root
- Change leafId from string to string|null for consistency with parentId
- Support optional branch summarization when switching
- Update buildSessionContext() to handle null leafId
- Add /tree to slash commands in interactive mode
Major changes:
- Replace monolithic SessionEvent with reason discriminator with individual
event types: session_start, session_before_switch, session_switch,
session_before_new, session_new, session_before_branch, session_branch,
session_before_compact, session_compact, session_shutdown
- Each event has dedicated result type (SessionBeforeSwitchResult, etc.)
- HookHandler type now allows bare return statements (void in return type)
- HookAPI.on() has proper overloads for each event with correct typing
Additional fixes:
- AgentSession now always subscribes to agent in constructor (was only
subscribing when external subscribe() called, breaking internal handlers)
- Standardize on undefined over null throughout codebase
- HookUIContext methods return undefined instead of null
- SessionManager methods return undefined instead of null
- Simplify hook exports to 'export type * from types.js'
- Add detailed JSDoc for skipConversationRestore vs cancel
- Fix createBranchedSession to rebuild index in persist mode
- newSession() now returns the session file path
Updated all example hooks, tests, and emission sites to use new event types.
When custom renderer returns a component with its own background,
don't wrap it in another background box. The nested bg resets
were causing padding to lose its background color.
- CompactionSummaryMessageComponent now extends Box, uses customMessageBg
- New BranchSummaryMessageComponent for branch summaries
- Both use same background color as HookMessageComponent for consistency
- Added Spacer before compaction/branch components in chat
- addMessageToChat: exhaustive switch for all AgentMessage roles
- renderSessionContext: delegates to addMessageToChat, special handling for assistant tool calls and tool results
- export-html formatMessage: exhaustive switch for all AgentMessage roles
- Removed isHookMessage, isBashExecutionMessage type guards in favor of role checks
- Fixed imports and removed unused getLatestCompactionEntry
- Rename HookAppMessage to HookMessage, isHookAppMessage to isHookMessage
- Remove entries array from SessionContext (use isHookMessage type guard instead)
- HookMessage.content now accepts string directly (not just array)
- Fix streamMessage type in AgentState (AppMessage, not Message)
- Rename CustomMessageComponent to HookMessageComponent
- Fix test hook to use pi.sendMessage
- Extract execCommand to src/core/exec.ts, shared by hooks and custom-tools
- Rename CustomMessageRenderer -> HookMessageRenderer
- Rename registerCustomMessageRenderer -> registerMessageRenderer
- Renderer now receives HookMessage instead of CustomMessageEntry
- CustomMessageComponent now has setExpanded() and responds to Ctrl+E toggle
- Re-export ExecOptions/ExecResult from exec.ts for backward compatibility
- Add AuthStorage class for credential storage (auth.json)
- Add ModelRegistry class for model management with API key resolution
- Add discoverAuthStorage() and discoverModels() discovery functions
- Add migration from legacy oauth.json and settings.json apiKeys to auth.json
- Remove configureOAuthStorage, defaultGetApiKey, findModel, discoverAvailableModels
- Remove apiKeys from Settings type and SettingsManager methods
- Rename getOAuthPath to getAuthPath
- Update SDK, examples, docs, tests, and mom package
Fixes#296
