The bell event is emitted when the ASCII BEL sequence is emitted to a pane in the window.

Defining an event handler doesn't alter wezterm's handling of the bell; the event supplements it and allows you to take additional action over the configured behavior.

The first event parameter is a window object that represents the gui window.

The second event parameter is a pane object that represents the pane in which the bell was rung, which may not be active pane--it could be in an unfocused pane or tab..

local wezterm = require 'wezterm'

wezterm.on('bell', function(window, pane)
  wezterm.log_info('the bell was rung in pane ' .. pane:pane_id() .. '!')

return {}
