pane:get_semantic_zone_at(x, y)

Since: Version 20230320-124340-559cb7b0

The functionality described in this section requires version 20230320-124340-559cb7b0 of wezterm, or a more recent version.

Resolves the semantic zone that encapsulates the supplied x and y coordinates.

x is the cell column index, where 0 is the left-most column. y is the stable row index.

Use pane:get_dimensions() to retrieve the currently valid stable index values for the top of scrollback and top of viewport.

-- If you have shell integration configured, returns the zone around
-- the current cursor position
function get_zone_around_cursor(pane)
  local cursor = pane:get_cursor_position()
  -- using x-1 here because the cursor may be one cell outside the zone
  local zone = pane:get_semantic_zone_at(cursor.x - 1, cursor.y)
  if zone then
    return pane:get_text_from_semantic_zone(zone)
  return nil

See Shell Integration for more information about semantic zones.
