pprint-tab

pprint-tab Function

Syntax:

pprint-tab kind colnum colinc &optional stream → nil

Arguments and Values:

kind—one of :line, :section, :line-relative, or :section-relative.

colnum—a non-negative integer .

colinc—a non-negative integer .

stream—an output stream designator .

Description:

Specifies tabbing to stream as performed by the standard ~T format directive. If stream is a pretty printing stream and the value of *print-pretty* is true, tabbing is performed; otherwise, pprint-tab has no effect.

The arguments colnum and colinc correspond to the two parameters to ~T and are in terms of ems. The kind argument specifies the style of tabbing. It must be one of :line (tab as by ~T), :section (tab as by ~:T, but measuring horizontal positions relative to the start of the dynamically enclosing section), :line-relative (tab as by ~@T), or :section-relative (tab as by ~:@T, but measuring

horizontal positions relative to the start of the dynamically enclosing section).

Exceptional Situations:

An error is signaled if kind is not one of :line, :section, :line-relative, or :section-relative.
