Arguments: configuration
Use of this accessor is deprecated. Programmers should bind or set the
associated global variable (*print-structure*
in this case) directly. The
default methods simply return or set the value of that global
variable.
Configurations contain information about the Lisp environment. The
current configuration is the value of (configuration
*system*)
(see configuration and *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.
