Variable *PRINT-PPRINT-DISPATCH*

●值类型:

a pprint dispatch table.

●初始值:

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.

●详情:

The pprint dispatch table which currently controls the pretty printer.

●例子: None.

●更多信息:

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

●说明:

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).
