ANSI Common Lisp  22 Printer 22.4 Dictionary of Printer
| 22.4.28 *print-right-margin* |
Variable |
- Value Type:
-
a non-negative integer, or nil.
- Initial Value:
-
nil.
- Description:
-
If it is non-nil, it specifies the right margin (as integer
number of ems) to use when the pretty printer is making
layout decisions.
If it is nil, the right margin is taken to be the maximum line length
such that output can be displayed without wraparound or truncation.
If this cannot be determined, an implementation-dependent value is used.
- Notes:
-
This measure is in units of ems in order to be compatible with
implementation-defined variable-width fonts while still not
requiring the language to provide support for fonts.
- Allegro CL Implementation Details:
-
None.
