27 * This module does not print terms and object properly, it has been created
28 * mainly for debugging reason. There is no guarantee that printed strings are
29 * re-parsable. Moreover, actually there is no way at all to proper print
30 * objects in a way that is re-parsable.
32 * TODO the proper implementation of a pp_obj function like the one below should
33 * be as follows. Change its type to
34 * pp_obj: NotationPt.obj -> NotationPres.markup
35 * and parametrize it over a function with the following type
36 * pp_term: NotationPt.term -> NotationPres.markup
37 * The obtained markup can then be printed using CicNotationPres.print_xml or
38 * BoxPp.render_to_string(s)
