print-pprint-dispatch (original) (raw)

ANSI Common Lisp 22 Printer 22.4 Dictionary of Printer

Value Type:

a pprint dispatch table.

Initial Value:

implementation-dependent, but the initial entries all use a special class of priorities that have the property that they are less than every priority that can be specified using set-pprint-dispatch, so that the initial contents of any entry can be overridden.

Description:

The pprint dispatch table which currently controls the pretty printer.

*print-pretty*, Section 22.2.1.4 Pretty Print Dispatch Tables

Notes:

The intent is that the initial value of this variable should cause `traditional' pretty printing of code. In general, however, you can put a value in *print-pprint-dispatch*that makes pretty-printed output look exactly like non-pretty-printed output. Setting *print-pretty* to _true_just causes the functions contained in the _current pprint dispatch table_to have priority over normal print-object methods; it has no magic way of enforcing that those functions actually produce pretty output. For details, see Section 22.2.1.4 Pretty Print Dispatch Tables.

Allegro CL Implementation Details:
