window:current_event()

Since: Version 20220807-113146-c2fee766

The functionality described in this section requires version 20220807-113146-c2fee766 of wezterm, or a more recent version.

Returns the current event. For now only implemented for mouse events.

This example prints the delta scroll value when you scroll up with your mouse wheel while holding CTRL:

local wezterm = require 'wezterm'

return {
  mouse_bindings = {
    {
      event = { Down = { streak = 1, button = { WheelUp = 1 } } },
      mods = 'CTRL',
      action = wezterm.action_callback(function(window, pane)
        -- note that you want `WheelDown` for a `WheelDown` event
        local delta = window:current_event().Down.button.WheelUp
        wezterm.log_info('delta is: ' .. delta)
      end),
    },
  },
}
