print-escape

Generic Function

Package: common-graphics

Arguments: configuration

Configurations contain information about the Lisp environment. The current configuration is the value of (configuration *system*). Among the information stored is the desired value for many standard global variables. These globals are set to these values when the system is initialized. Changing a value in the configuration changes the current value of the global. Accessors are typically named with a symbol named the same as the global variable but without the surrounding stars (if any).

This function accesses the value of the print-escape property, which corresponds to the *print-escape* global variable. This variable controls whether objects are printed with escapes (which allows them to be read back correctly). For example, the character #\a prints as a or as #\a as *print-escape* it nil to t:

> (let ((*print-escape* nil))
     (write #\a) (terpri)
     (setq *print-escape* t)
     (write #\a)
     nil)
a
#\a
nil

print-escape is a property of the configuration class.

You can examine and change configuration options with the inspector. Choose Tools | Inspect System Data | Configuration Options.
