pprint-tab kind colnum colinc &optional stream ⇒ nil
| 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. |
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).
An error is signaled if kind is not one of :line,
:section, :line-relative, or :section-relative.
