class FractionNode

  • supers: Node

Warning: never assign a node list to the num, or denom field unless you are sure its internal link structure is correct, otherwise an error can result.

Example:

assert.node_type("fraction", nil, {
  id = "fraction (20)",
  fields = {
    "prev (-1)",
    "next (0)",
    "id (1)",
    "subtype (2)",
    "attr (3)",
    "width (4)",
    "num (5)",
    "denom (6)",
    "left (7)",
    "right (8)",
    "middle (9)",
    "fam (10)",
    "options (11)",
  },
})
