*print-escape*

∗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 Section 22.1.3 (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.

Expanded Reference: *print-escape*
