*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.
