Struct BashExecution 

pub struct BashExecution { /* private fields */ }

Bash execution component - renders a bash command with borders, spinner, and output.

Matches pi’s BashExecutionComponent design:

• Spacer (1 blank line) above top border
• Top/bottom borders in bashMode color (or dim for !! commands)
• Command header with $ prefix
• Spinner while running (uses Loader component)
• Streaming output in muted color (no ANSI)
• Collapse/expand support showing FIRST N lines (preview truncation)
• Status line with exit code, duration, cancellation, truncation warnings
• Width-aware visual truncation for collapsed preview

Implementations

impl BashExecution

pub fn new(command: impl Into<String>) -> Self

pub fn append_output(&mut self, line: impl Into<String>)

pub fn append_chunk(&mut self, chunk: &str)

Append a chunk of output that may contain newlines. Handles splitting into lines similar to pi’s appendOutput (preserving incomplete last line).

pub fn set_complete(&mut self, exit_code: i32)

pub fn set_cancelled(&mut self)

pub fn set_error(&mut self, msg: impl Into<String>)

pub fn set_expanded(&mut self, expanded: bool)

pub fn set_exclude_from_context(&mut self, exclude: bool)

pub fn set_full_output_path(&mut self, path: impl Into<String>)

pub fn set_truncated(&mut self, truncated: bool)

pub fn set_duration_secs(&mut self, secs: f64)

Set the execution duration in seconds.

pub fn set_duration_from_content(&mut self, content: &str)

Parse and set duration from result content (format: [Xs] at end of string).

pub fn is_expanded(&self) -> bool

pub fn get_output(&self) -> String

Get the raw output (for building messages sent to the LLM).

pub fn get_command(&self) -> String

Get the command that was executed.

Trait Implementations

impl Component for BashExecution

fn set_expanded(&mut self, expanded: bool)

Toggle expanded/collapsed state. No-op by default. Override for components that support expand/collapse (tool results, messages, etc.).

fn render(&self, width: usize) -> Vec<String>

Render to lines for the given viewport width. Each returned string MUST NOT exceed width in visible width.

fn invalidate(&mut self)

Mark this component as needing re-render. Called when internal state changes (output received, expanded toggled, etc.).

fn handle_input(&mut self, _key: &KeyEvent) -> bool

Handle keyboard input. Return true if consumed.

fn handle_paste(&mut self, _text: &str)

Handle a paste event (text from bracketed paste mode). Default no-op; override to process pasted content.

fn is_dirty(&self) -> bool

Check if this component needs re-render. Default: always re-render (conservative).

fn clear_dirty(&mut self)

Clear dirty flag after successful render.

fn cache_key(&self, _width: usize) -> Option<RenderCacheKey>

Get the cache key for this component’s current state. Return None to disable caching (always re-render).

fn get_cached_render(&self) -> Option<&RenderCache>

Get cached render output, if available and valid.

fn set_cached_render(&mut self, _cache: RenderCache)

Store render output in cache.

fn is_focusable(&self) -> bool

Whether this component wants focus (for IME cursor positioning).

fn set_hide_thinking(&mut self, _hide: bool)

Toggle thinking block visibility. No-op by default. Override for components that display thinking content (AssistantMessageComponent).
