28 ;; These are extensions to Emacs Lisp that provide a degree of
29 ;; Common Lisp compatibility, beyond what is already built-in
32 ;; This package was written by Dave Gillespie; it is a complete
33 ;; rewrite of Cesar Quiroz's original cl.el package of December 1986.
35 ;; Bug reports, comments, and suggestions are welcome!
37 ;; This file contains the portions of the Common Lisp extensions
38 ;; package which should always be present.
43 ;; Once Emacs 19 becomes standard, many things in this package which are
44 ;; messy for reasons of compatibility can be greatly simplified. For now,
45 ;; I prefer to maintain one unified version.
50 ;; Version 2.02 (30 Jul 93):
51 ;; * Added "cl-compat.el" file, extra compatibility with old package.
52 ;; * Added `lexical-let' and `lexical-let*'.
53 ;; * Added `define-modify-macro', `callf', and `callf2'.
54 ;; * Added `ignore-errors'.
55 ;; * Changed `(setf (nthcdr N PLACE) X)' to work when N is zero.
56 ;; * Merged `*gentemp-counter*' into `*gensym-counter*'.
57 ;; * Extended `subseq' to allow negative START and END like `substring'.
58 ;; * Added `in-ref', `across-ref', `elements of-ref' loop clauses.
59 ;; * Added `concat', `vconcat' loop clauses.
60 ;; * Cleaned up a number of compiler warnings.
62 ;; Version 2.01 (7 Jul 93):
63 ;; * Added support for FSF version of Emacs 19.
64 ;; * Added `add-hook' for Emacs 18 users.
65 ;; * Added `defsubst*' and `symbol-macrolet'.
66 ;; * Added `maplist', `mapc', `mapl', `mapcan', `mapcon'.
67 ;; * Added `map', `concatenate', `reduce', `merge'.
68 ;; * Added `revappend', `nreconc', `tailp', `tree-equal'.
69 ;; * Added `assert', `check-type', `typecase', `typep', and `deftype'.
70 ;; * Added destructuring and `&environment' support to `defmacro*'.
71 ;; * Added destructuring to `loop', and added the following clauses:
72 ;; `elements', `frames', `overlays', `intervals', `buffers', `key-seqs'.
73 ;; * Renamed `delete' to `delete*' and `remove' to `remove*'.
74 ;; * Completed support for all keywords in `remove*', `substitute', etc.
75 ;; * Added `most-positive-float' and company.
76 ;; * Fixed hash tables to work with latest Lucid Emacs.
77 ;; * `proclaim' forms are no longer compile-time-evaluating; use `declaim'.
78 ;; * Syntax for `warn' declarations has changed.
79 ;; * Improved implementation of `random*'.
80 ;; * Moved most sequence functions to a new file, cl-seq.el.
81 ;; * Moved `eval-when' into cl-macs.el.
82 ;; * Moved `pushnew' and `adjoin' to cl.el for most common cases.
83 ;; * Moved `provide' forms down to ends of files.
84 ;; * Changed expansion of `pop' to something that compiles to better code.
85 ;; * Changed so that no patch is required for Emacs 19 byte compiler.
86 ;; * Made more things dependent on `optimize' declarations.
87 ;; * Added a partial implementation of struct print functions.
88 ;; * Miscellaneous minor changes.
91 ;; * First public release of this package.
