print-structure

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-structure property, which corresponds to the *print-structure* global variable. This global variable controls the print representation of structures. A random-state object is a structure. The following shows how this value affects printing of a random-state object (we have deleted values when *print-structure* is true to save space, as indicated by […]):

> (let ((*print-structure* nil))
     (print *random-state*)
     (setq *print-structure* t)
     (print *random-state*)
     nil)

#<random-state @ #x205a7f2a> 
#S(random-state :seed 45915826886865
                :fixseed
                #(301710475 9180431 285773896 […])) 
nil

print-structure is a property of the configuration class.

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