I've been meaning to do this for a while; this commit moves the escape sequence parsing into the thread that reads the pty output which achieves two goals: * Large escape sequences (eg: image protocols) that span multiple 4k buffers can be processed without ping-ponging between the reader thread and the main gui thread * That parsing can happen in the reader thread, keeping the gui thread more responsive. These changes free up the CPU during intensive operations such as timg video playback. This is a slight layering violation, in that this processing really belongs to local pane (or any pane that embeds Terminal), rather than generically at the Mux layer, but it's not any worse a violation than `advance_bytes` already was. refs: https://github.com/wez/wezterm/issues/537 |
