This is by means of two new object methods, print_preprocess (detecting circularities), and nsubst_structures_descend (replacing placeholders with the read objects). Expose the substitution to Lisp via #'nsubst and its new :descend-structures keyword. Store information as to whether symbols are interned in obarray or not in their header, making checking for keywords and uninterned symbols (and thus printing) cheaper. Default print_gensym to t, as Common Lisp does, and as a more-than-decade old comment suggests. lisp/ChangeLog addition: 2011-09-04 Aidan Kehoe <kehoea@parhasard.net> * bytecomp.el (byte-compile-output-file-form): * bytecomp.el (byte-compile-output-docform): Bind print-circle, print-continuous-numbering in these functions, now those variables are available. * lisp.el (forward-sexp): * lisp.el (backward-sexp): Recognise leading #N= as being part of an expression. tests/ChangeLog addition: 2011-09-04 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-reader-tests.el: * automated/lisp-tests.el (literal-with-uninterned): * automated/symbol-tests.el (foo): Test print-circle, for printing (mutually-)recursive and circular structures. Bind print-continuous-numbering where appropriate.

;;; Commentary:

;; The following commentary is completely out of date.  I would like to
;; delete it, but it serves as a useful reminder as to how things used to
;; work.

;; !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
;; Special formatting conventions are used in this file!

;; a backslash-newline is used at the beginning of a documentation string
;; when that string should be stored in the file lib-src/DOCnnn, not in core.

;; Such strings read into Lisp as numbers (during the pure-loading phase).

;; But you must obey certain rules to make sure the string is understood
;; and goes into lib-src/DOCnnn properly.  Otherwise, the string will not go
;; anywhere!

;; The doc string must appear in the standard place in a call to
;; defun, autoload, defvar or defconst.  No Lisp macros are recognized.
;; The open-paren starting the definition must appear in column 0.

;; In defvar and defconst, there is an additional rule:
;; The double-quote that starts the string must be on the same
;; line as the defvar or defconst.
;; !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

;; **********************************************************************
;; You should never need to write autoloads by hand and put them here.

;; It is no longer necessary.  Instead use autoload.el to maintain them
;; for you.  Just insert ";;;###autoload" before defuns or defmacros you
;; want to be autoloaded, or other forms you want copied into loaddefs.el
;; (defvars, key definitions, etc.).  For example, 
;;	;;;###autoload
;;	(defun foobar () ....)
;;	;;;###autoload (define-key global-map "f" 'foobar)
;;	;;;###autoload
;;	(defvar foobar-var nil "\
;;	This is foobar-var's doc-string.")

;; Then do M-x update-file-autoloads on the file to update loaddefs.el.

;; You can also use M-x update-directory-autoloads to update the autoloads
;; in loaddefs.el for all .el files in the lisp/ directory, or M-x
;; update-autoloads-here to update the autoloads for each file that
;; already has an autoload section in this file.
;; **********************************************************************


;;; Code:

;; These variables are used by autoloadable packages.
;; They are defined here so that they do not get overridden
