22.4.20 *print-escape* [Variable]

Value Type::

a generalized boolean.

Initial Value::

true.

Description::

If false, escape characters and package prefixes are not output when an expression is printed.

If true, an attempt is made to print an expression in such a way that it can be read again to produce an equal expression. (This is only a guideline; not a requirement. See *print-readably*.)

For more specific details of how the value of *print-escape* affects the printing of certain types, see Default Print-Object Methods.

Examples::

 (let ((*print-escape* t)) (write #\a))
 |>  #\a
⇒  #\a
 (let ((*print-escape* nil)) (write #\a))
 |>  a
⇒  #\a

Affected By::

princ, prin1, format

See Also::

write , readtable-case

Notes::

princ effectively binds *print-escape* to false. prin1 effectively binds *print-escape* to true.
