Defined in:
lib/kward/pty/output_sink.rb

Overview

Forwards PTY output immediately and optionally keeps a bounded byte copy.

The runner only depends on the sink's write method and optional flush method. Capture is deliberately byte-oriented so PTY chunk boundaries have no effect on the retained output.
