Instance Method Details

#append_output(content) ⇒ Object

Append output to the output area.

If a progress indicator is currently active (somewhere in the buffer), rotate it to the tail after the append: business content ends up above, the spinner stays at the bottom. Without this, every subsequent ticker tick on a non-tail progress entry would trigger a full output repaint (visible flicker) and the visual order would have business messages appearing below the spinner.

#show_info(message, prefix_newline: true) ⇒ Object

#show_progress(message = nil, prefix_newline: true, progress_type: "thinking", phase: "active", metadata: {}) ⇒ Object

Legacy shim: show_progress(message, phase:, progress_type:, …)

This method preserves the pre-refactor API so existing call sites (Agent#run, Agent#think, LlmCaller retry, trigger_idle_compression, MemoryUpdater) keep working until they’re migrated to the owned- handle API.

Each progress_type owns its own handle slot so two concurrent background flows (e.g. idle compression + thinking) can coexist without stomping on each other — exactly the race that caused the yellow/gray flicker bug.

#start_progress(message: nil, style: :primary, quiet_on_fast_finish: false) ⇒ Octo::UI2::ProgressHandle

Start a new progress indicator and return its owned handle.

Parameters:

  • message (String) (defaults to: nil) —

    Initial progress message.

  • style (Symbol) (defaults to: :primary) —

    :primary (foreground, yellow, bumps sessionbar) or :quiet (background, gray, no sessionbar change).

  • quiet_on_fast_finish (Boolean) (defaults to: false) —

    See ProgressHandle — when true, a finish that elapses under FAST_FINISH_THRESHOLD_SECONDS removes the entry instead of leaving a permanent final frame. Preferred for tool-execution wrappers.

Returns:

#stream_thinking_progress(input_tokens:, output_tokens:) ⇒ Object

Stream-only update for the live thinking progress. Unlike show_progress(progress_type: “thinking”, phase: “active”), this NEVER creates a new handle — if no thinking handle is currently alive (e.g. we’re inside an idle-compression call_llm where only the quiet “Compressing…” handle is on the stack), the streamed token counts are silently dropped instead of spawning a primary spinner that would push the compression progress off-screen.
