Implements support for ${@:N} and ${@:N:L} syntax to slice argument arrays
in prompt templates, following bash conventions.
Syntax:
- ${@:N} - All arguments from Nth position onwards (1-indexed)
- ${@:N:L} - L arguments starting from Nth position
Features:
- Bash-style slicing familiar to shell users
- 1-indexed for consistency with $1, $2, etc.
- Processes before simple $@ to avoid conflicts
- No recursive substitution of patterns in arguments
- Comprehensive edge case handling
Examples:
- ${@:2} with ["a", "b", "c"] -> "b c"
- ${@:2:1} with ["a", "b", "c"] -> "b"
- ${@:99} with ["a", "b"] -> "" (empty, out of range)
Test coverage: 24 new tests, all passing (73 total)
Closes#769
- Add Focusable interface for components that need hardware cursor positioning
- Add CURSOR_MARKER (APC escape sequence) for marking cursor position in render output
- Editor and Input components implement Focusable and emit marker when focused
- TUI extracts cursor position from rendered output and positions hardware cursor
- Track hardwareCursorRow separately from cursorRow for differential rendering
- visibleWidth() and extractAnsiCode() now handle APC sequences
- Update overlay-test.ts example to demonstrate Focusable usage
- Add documentation for Focusable interface in docs/tui.md
Closes#719, closes#525
The Editor component now accepts TUI as the first constructor parameter,
enabling it to query terminal dimensions. When content exceeds available
height, the editor scrolls vertically keeping the cursor visible.
Features:
- Max editor height is 30% of terminal rows (minimum 5 lines)
- Page Up/Down keys scroll by page size
- Scroll indicators show lines above/below: ─── ↑ 5 more ───
Breaking change: Editor constructor signature changed from
new Editor(theme)
to
new Editor(tui, theme)
fixes#732
When stdin is piped (not a TTY), read the content and treat it as the
first message. Since interactive mode requires a TTY for keyboard input,
print mode is automatically enabled.
- echo foo | pi -> equivalent to pi -p foo
- echo foo | pi -p -> equivalent to pi -p foo
- RPC mode unaffected (uses stdin for JSON-RPC)
fixes#708
- Skill commands (/skill:name) now expanded in AgentSession instead of
interactive mode, enabling them in RPC and print modes
- Input event can now intercept /skill:name before expansion
- Updated extensions.md with clearer input event docs and processing order
- Updated rpc.md: hook -> extension terminology, added skill expansion mentions
- Added PR attribution to changelog entries for #761
* feat(coding-agent): add input event for extension input interception
Extensions can now intercept, transform, or handle user input before the
agent processes it. Three result types: continue (pass through), transform
(modify text/images), handled (respond without LLM). Handlers chain
transforms and short-circuit on handled. Source field identifies origin.
* fix: make source public, use if/else over ternary
* fix: remove response field, extension handles own UI
Resolves pi-internal:// paths to the coding-agent package directory,
allowing the model to read internal documentation. Appends a hint
showing the filesystem path and instructing to use it for further reads.
- align Codex Responses provider with Pi static instructions
- simplify Codex request/stream handling and cleanup exports
- keep legacy OpenCode Codex prompt for testing until Pi prompt is allowlisted
* Add direct filter shortcuts for Tree mode
- Add Ctrl+D for default filter
- Add Ctrl+T for no-tools filter (toggles with default)
- Add Ctrl+U for user-only filter (toggles with default)
- Add Ctrl+L for labeled-only filter (toggles with default)
- Add Ctrl+A for all filter (toggles with default)
- Keep existing Ctrl+O / Shift+Ctrl+O cycle shortcuts
- Update help text to show new shortcuts
* simplify tree selector shortcut line
Shift+P conflicts with typing capital P. Ctrl+Alt+P is cross-platform
safe and doesn't conflict with common shortcuts like:
- Ctrl+Shift+P (command palette on Windows/VS Code)
- Shift+Alt+P (types π on macOS)
* Add Amazon Bedrock models test suite for agent package
Tests basic prompts, multi-turn conversations with thinking, and
synthetic thinking signatures across all Bedrock models.
Known issues are categorized and skipped:
- Models requiring inference profile (5)
- Invalid model IDs for us-east-1 region (6)
- Max tokens config exceeds model limit (2)
- No signature support in reasoningContent (10)
- Rejects reasoning content in user messages (25)
- Validates signature format - Anthropic newer models (7)
* Fix Bedrock signature support for non-Anthropic models
Only include the signature field in reasoningContent.reasoningText for
Anthropic Claude models. Other models (OpenAI, Qwen, Minimax, Moonshot,
etc.) reject this field with:
"This model doesn't support the reasoningContent.reasoningText.signature field"
This fix enables multi-turn conversations with thinking content for
10 additional Bedrock models that previously failed.

* Add a CHANGELOG entry
Follow-up to #717. Replaces all remaining hardcoded keybinding hints with configurable ones.
- Add pasteImage to AppAction so it can be configured in keybindings.json
- Create keybinding-hints.ts with reusable helper functions:
- editorKey(action) / appKey(keybindings, action) - get key display string
- keyHint(action, desc) / appKeyHint(kb, action, desc) / rawKeyHint(key, desc) - styled hints
- Export helpers from components/index.ts for extensions
- Update all components to use configured keybindings
- Remove now-unused getDisplayString() from KeybindingsManager and EditorKeybindingsManager
- Use keybindings.matches() instead of matchesKey() for pasteImage in custom-editor.ts
