Trait Implementations

impl ExtensionUi for NoUi

fn has_ui(&self) -> bool

Whether a person can answer dialogs.

fn notify(&self, _message: &str, _kind: NotifyKind)

Shows a message.

fn shutdown(&self)

pi’s ctx.shutdown(): the mode exits once the agent is idle.

fn notify_untyped(&self, message: &str)

Shows a message that names no kind. Hosts show it as information, and RPC forwards it without a kind, as pi does.

fn select( &self, _title: &str, _options: Vec<String>, _dialog: DialogOptions, ) -> BoxFuture<'static, Option<String>>

Asks to pick one of options, resolving to None when cancelled.

fn input( &self, _title: &str, _placeholder: Option<&str>, _dialog: DialogOptions, ) -> BoxFuture<'static, Option<String>>

Asks for a line of text, resolving to None when cancelled.

fn confirm( &self, _title: &str, _message: &str, _dialog: DialogOptions, ) -> BoxFuture<'static, bool>

Asks a yes or no question, resolving to false when cancelled.

fn editor( &self, _title: &str, _prefill: Option<&str>, ) -> BoxFuture<'static, Option<String>>

Asks for multi-line text starting from prefill, resolving to None when cancelled.

fn set_status(&self, _key: &str, _text: Option<&str>)

Sets the footer status key, or clears it.

fn set_widget( &self, _key: &str, _widget: Option<Widget>, _placement: Option<Placement>, )

Sets widget key, or removes it. Without a placement it goes above the editor.

fn set_footer(&self, _component: Option<RemoteComponent>)

Replaces the footer, or restores the built-in one.

fn set_header(&self, _component: Option<RemoteComponent>)

Replaces the startup header, or restores the built-in one.

fn set_title(&self, _title: &str)

Sets the terminal title.

fn refresh_completions(&self)

Completions an extension computed in the background are ready. The editor asks for its suggestions again.

fn set_working_message(&self, _message: Option<&str>)

Sets the message shown while the agent works, or restores the default.

fn set_working_visible(&self, _visible: bool)

Shows or hides the indicator shown while the agent works.

fn set_working_indicator(&self, _indicator: Option<WorkingIndicator>)

Sets the animation shown while the agent works, or restores the default spinner.

fn set_hidden_thinking_label(&self, _label: Option<&str>)

Sets the label of hidden thinking blocks, or restores the default.

fn set_editor_text(&self, _text: &str)

Replaces the editor’s text.

fn paste_to_editor(&self, text: &str)

Pastes into the editor as a terminal paste would.

fn editor_text(&self) -> String

The editor’s text.

fn shows_components(&self) -> bool

Whether ExtensionUi::custom and component widgets are shown.

fn set_editor(&self, _editor: Option<RemoteComponent>, _embeds_status: bool)

Replaces the editor with editor, or restores the built-in one. embeds_status when the editor shows the working status in its top border.

fn editor_changed(&self, _text: &str)

The extension’s editor now holds text, paste markers expanded.

fn editor_submit(&self, _text: &str)

The extension’s editor submitted text.

fn editor_action(&self, _action: &str)

The extension’s editor asks for app action action, a key binding id such as app.interrupt.

fn set_terminal_input( &self, _runtime: u64, _listeners: Option<Arc<dyn ComponentHost>>, )

Starts passing raw input through the onTerminalInput listeners of extension runtime runtime, which listeners runs, or stops with None. Runtimes’ listeners see input in the order they started.

fn set_autocomplete( &self, _providers: Arc<dyn ComponentHost>, _triggers: Vec<String>, )

Completes through the providers composed with addAutocompleteProvider, which providers runs. triggers open completion too. They replace the providers of the runtime that set them before.

fn suggestions(&self, _request: Value) -> BoxFuture<'static, Value>

What the built-in provider suggests for pi’s provider arguments request, {"lines", "cursorLine", "cursorCol", "force"} with UTF-16 columns: pi’s AutocompleteSuggestions, or Null.

fn apply_completion(&self, _request: &Value) -> Value

The built-in provider’s applyCompletion for {"lines", "cursorLine", "cursorCol", "item", "prefix"}: {"lines", "cursorLine", "cursorCol"}.

fn editor_shortcut(&self, _data: &str) -> bool

Whether raw input data is an extension shortcut, which then runs.

fn keybindings(&self) -> Value

The key bindings components match keys against: {"kitty", "bindings": {id: [key]}, "actions": [id]}, where actions are the app actions an extension’s editor can ask for. Null keeps pi-tui’s defaults.

fn custom(&self, _component: RemoteComponent, _options: CustomOptions)

Shows component with keyboard focus until ExtensionUi::close.

fn close(&self, _component: RemoteComponent)

Removes the custom component component.

fn drop_components(&self, _runtime: u64)

Removes the editor, widgets, footer and header that extension runtime runtime showed, which it lost when it restarted. The built-in editor, footer and header return.

fn mcp_manager(&self, _screen: McpScreen)

Shows a screen of the /mcp manager with keyboard focus, opening the manager. McpScreen::Close closes it. Without the TUI the screen is dropped, which closes its menu.

fn request_render(&self)

Components changed and need rendering.

fn renderers_changed(&self)

An extension registered transcript renderers or a Markdown transformer after its session started. What draws next uses them.

fn tools_expanded(&self) -> bool

Whether tool output is expanded.

fn set_tools_expanded(&self, _expanded: bool)

Expands or collapses tool output.

fn terminal(&self) -> Option<Receiver<TerminalState>>

The terminal’s state, kept current as it changes, or None without a terminal, as in print, JSON and RPC modes.

fn footer_data(&self) -> Value

What custom footers read: {"gitBranch", "statuses": [[key, text]], "providers"}.

fn theme(&self) -> Value

The theme as escape sequences, and the colors they come from: {"name", "mode", "fg": {token: sequence}, "bg": {token: sequence}, "dim": [token], "colors": {token: color}}. Null leaves text unstyled.

fn get_theme(&self, _name: &str) -> Value

The theme called name, as ExtensionUi::theme describes it, or Null when there is none.

fn all_themes(&self) -> Value

pi’s getAllThemes: the themes ExtensionUi::set_theme can switch to, as [{"name", "path"}] with no path for a theme without a file. Empty without a UI that switches themes, as in pi’s RPC mode.

fn set_theme(&self, _theme: &Value) -> Result<(), String>

Switches to theme: a theme name, which is saved as /settings saves it, or a theme document {"name", "appearance", "colors"}, which is not saved. The error says why it could not.

fn extension_error( &self, path: &str, _event: &str, error: &str, _stack: Option<&str>, )

A handler of extension path failed on event, with the error’s stack when the runtime gave one. By default it reports as print mode does.
