Struct ChatEditor 

pub struct ChatEditor {
    pub editor: Editor,
    /* private fields */
}

Rab-specific chat editor that wraps the core tui::Editor.

Mirrors pi’s CustomEditor pattern: ChatEditor handles keyboard input and dispatches app-level actions (escape, submit, model selector, etc.) as an InputAction enum, while text-editing keys are delegated to the inner Editor. The app layer matches on InputAction to perform side effects.

Key differences from pi’s CustomEditor:

• Text-editing keys (Ctrl+Z undo, Ctrl+J newline, Up/Down history, Tab, PageUp/PageDown, etc.) are delegated entirely to the inner Editor, matching pi’s editor-centric handling.
• Only app-level keybindings (interrupt, exit, model selector, help, etc.) are intercepted here.

Fields

editor: Editor

Implementations

impl ChatEditor

pub fn new(_theme: &dyn Theme, cwd: PathBuf) -> Self

pub fn set_slash_commands(&mut self, commands: Vec<SlashCommand>)

Set the available slash commands for autocomplete.

pub fn set_extension_shortcut_handler( &mut self, handler: Box<dyn FnMut(&KeyEvent) -> bool + Send>, )

Set a handler for extension-registered shortcuts (pi-style). The handler receives the key event and returns true if the key was handled.

pub fn on_action(&mut self, action: &str, handler: Box<dyn FnMut() + Send>)

Register a dynamic app action handler (pi-style). When the keybinding for action is pressed, handler is called. Does NOT override built-in actions (Escape, Ctrl+C, Ctrl+D, Enter).

pub fn check_autocomplete(&mut self)

After programmatic set_text, trigger autocomplete check (pi-style).

pub fn set_cwd(&mut self, cwd: PathBuf)

Update the working directory.

pub fn update_border_color( &mut self, thinking_level: Option<&str>, theme: &dyn Theme, )

Handle keyboard input. Mirrors pi’s CustomEditor.handleInput:

1. Checks app-level keys (escape, clear, submit, model selector, etc.) and returns the corresponding InputAction for the app layer to handle.
2. All other keys are delegated to the inner Editor for text editing, including Ctrl+Z (undo), Ctrl+J (newline), Up/Down (history), Tab (autocomplete), PageUp/PageDown (scroll), etc.

This keeps app-level side effects (aborting agent, opening overlays, etc.) in the app layer while keeping text-editing logic in the Editor component. Update editor border color based on thinking level or bash mode. Matches pi’s updateEditorBorderColor().

• Bash mode (text starts with !): uses bashMode color
• Otherwise: uses thinking level color (thinkingOff..thinkingXhigh)

pub fn handle_input(&mut self, key: &KeyEvent) -> InputAction
