Description

SAVE-OBJECT is a recursive function which writes an ASCII representation of a LISP object to a designated file.

kr010622: in other words, it serializes arbitrary LISP data structures, very similar to what the "pickle" operation does in the scripting language python.

NOTE: SAVE-OBJECT doesnt need a special LOAD function! You can load files created by SAVE-OBJECT with the standard LOAD function

Usage

To save:

(SAVE-OBJECT (list 10 20 30) "myfile.lisp")    ,

To restore the data in the saved list:

(LOAD "myfile.lisp")

Where the newly restored data ends up:

db:*db-input* == (LIST 10 20 30)

Objects which may be saved include:

• symbols, keywords, characters, strings, and pathnames.
• numbers, including integer, rational, complex, and floating point.
• vectors and multi-dimensional arrays.
• objects produced by DEFSTRUCT.
• CLOS (PCL) instances, and CLOS(PCL) classes.
• hash tables.
• compiled functions, represented as (FUNCTION ), internally.
• generic functions, method objects, and class objects.
• conses and lists.
• circular conses and lists (new)
• user defined methods may be defined for arbitrary objects, such as images.
• readtables (a kludge for now)
• CLIM objects (saved as ordinary CLOS instances)
