07b3798c 27;;; Commentary:
fcd73769
RS
28
29;; These are extensions to Emacs Lisp that provide a degree of
30;; Common Lisp compatibility, beyond what is already built-in
31;; in Emacs Lisp.
32;;
33;; This package was written by Dave Gillespie; it is a complete
34;; rewrite of Cesar Quiroz's original cl.el package of December 1986.
35;;
fcd73769
RS
36;; Bug reports, comments, and suggestions are welcome!
37
38;; This file contains the portions of the Common Lisp extensions
39;; package which should always be present.
40
41
07b3798c 42;;; Future notes:
fcd73769
RS
43
44;; Once Emacs 19 becomes standard, many things in this package which are
45;; messy for reasons of compatibility can be greatly simplified. For now,
46;; I prefer to maintain one unified version.

07b3798c 49;;; Change Log:
fcd73769
RS
50
51;; Version 2.02 (30 Jul 93):
52;; * Added "cl-compat.el" file, extra compatibility with old package.
53;; * Added `lexical-let' and `lexical-let*'.
54;; * Added `define-modify-macro', `callf', and `callf2'.
55;; * Added `ignore-errors'.
56;; * Changed `(setf (nthcdr N PLACE) X)' to work when N is zero.
57;; * Merged `*gentemp-counter*' into `*gensym-counter*'.
58;; * Extended `subseq' to allow negative START and END like `substring'.
59;; * Added `in-ref', `across-ref', `elements of-ref' loop clauses.
60;; * Added `concat', `vconcat' loop clauses.
61;; * Cleaned up a number of compiler warnings.
62
63;; Version 2.01 (7 Jul 93):
64;; * Added support for FSF version of Emacs 19.
65;; * Added `add-hook' for Emacs 18 users.
66;; * Added `defsubst*' and `symbol-macrolet'.
67;; * Added `maplist', `mapc', `mapl', `mapcan', `mapcon'.
68;; * Added `map', `concatenate', `reduce', `merge'.
69;; * Added `revappend', `nreconc', `tailp', `tree-equal'.
70;; * Added `assert', `check-type', `typecase', `typep', and `deftype'.
71;; * Added destructuring and `&environment' support to `defmacro*'.
72;; * Added destructuring to `loop', and added the following clauses:
73;; `elements', `frames', `overlays', `intervals', `buffers', `key-seqs'.
74;; * Renamed `delete' to `delete*' and `remove' to `remove*'.
75;; * Completed support for all keywords in `remove*', `substitute', etc.
76;; * Added `most-positive-float' and company.
77;; * Fixed hash tables to work with latest Lucid Emacs.
78;; * `proclaim' forms are no longer compile-time-evaluating; use `declaim'.
79;; * Syntax for `warn' declarations has changed.
80;; * Improved implementation of `random*'.
81;; * Moved most sequence functions to a new file, cl-seq.el.
82;; * Moved `eval-when' into cl-macs.el.
83;; * Moved `pushnew' and `adjoin' to cl.el for most common cases.
84;; * Moved `provide' forms down to ends of files.
85;; * Changed expansion of `pop' to something that compiles to better code.
86;; * Changed so that no patch is required for Emacs 19 byte compiler.
87;; * Made more things dependent on `optimize' declarations.
88;; * Added a partial implementation of struct print functions.
89;; * Miscellaneous minor changes.
90
91;; Version 2.00:
92;; * First public release of this package.
