class HlistNode

  • supers: ListNode

An hlist node stands for a box that was made from a horizontal list.

A warning: never assign a node list to the head field unless you are sure its internal link structure is correct, otherwise an error may result.

Note: the field name head and list are both valid. Sometimes it makes more sense to refer to a list by head, sometimes list makes more sense.

Example:

assert.node_type("hlist", nil, {
  id = "hlist (0)",
  subtypes = {
    "unknown (0)",
    "line (1)",
    "box (2)",
    "indent (3)",
    "alignment (4)",
    "cell (5)",
    "equation (6)",
    "equationnumber (7)",
    "math (8)",
    "mathchar (9)",
    "hextensible (10)",
    "vextensible (11)",
    "hdelimiter (12)",
    "vdelimiter (13)",
    "overdelimiter (14)",
    "underdelimiter (15)",
    "numerator (16)",
    "denominator (17)",
    "limits (18)",
    "fraction (19)",
    "nucleus (20)",
    "sup (21)",
    "sub (22)",
    "degree (23)",
    "scripts (24)",
    "over (25)",
    "under (26)",
    "accent (27)",
    "radical (28)",
  },
  fields = {
    "prev (-1)",
    "next (0)",
    "id (1)",
    "subtype (2)",
    "attr (3)",
    "width (4)",
    "depth (5)",
    "height (6)",
    "dir (7)",
    "shift (8)",
    "glue_order (9)",
