MakeBoxes

MakeBoxes[expr,form]

is the low‐level function used in Wolfram System sessions to convert expressions into boxes.

MakeBoxes[expr]

is the function to convert expr to StandardForm boxes.

Details

  • MakeBoxes does not evaluate expr.
  • form can be StandardForm, TraditionalForm, or any other format represented using boxes.
  • You can give definitions for MakeBoxes[expr,form] to specify your own rules for how expressions should be converted to boxes. »
  • MakeBoxes is not automatically called on the results it generates. This means that explicit MakeBoxes calls must typically be inserted into definitions that are given.
  • If you change the output format for an expression by giving a definition for MakeBoxes, there is no guarantee that output you get will subsequently be able to be interpreted by the Wolfram Language.
  • Definitions you give for MakeBoxes will override built‐in Wolfram Language rules for generating output.
