Move the heavy lifting from cl-seq.el to C.
src/ChangeLog addition:
2010-12-30 Aidan Kehoe <kehoea@parhasard.net>
Move the heavy lifting from cl-seq.el to C, finally making those
functions first-class XEmacs citizens, with circularity checking,
built-in support for tests other than #'eql, and as much
compatibility with current Common Lisp as Paul Dietz' tests require.
* fns.c (check_eq_nokey, check_eq_key, check_eql_nokey)
(check_eql_key, check_equal_nokey, check_equal_key)
(check_equalp_nokey, check_equalp_key, check_string_match_nokey)
(check_string_match_key, check_other_nokey, check_other_key)
(check_if_nokey, check_if_key, check_match_eq_key)
(check_match_eql_key, check_match_equal_key)
(check_match_equalp_key, check_match_other_key): New. These are
basically to provide function pointers to be used by Lisp
functions that take TEST, TEST-NOT and KEY arguments.
(get_check_match_function_1, get_check_test_function)
(get_check_match_function): These functions work out which of the
previous list of functions to use, given the keywords supplied by
the user.
(count_with_tail): New. This is the bones of #'count.
(list_count_from_end, string_count_from_end): Utility functions
for #'count.
(Fcount): New, moved from cl-seq.el.
(list_position_cons_before): New. The implementation of #'member*,
and important in implementing various other functions.
(FmemberX, Fadjoin, FassocX, FrassocX, Fposition, Ffind)
(FdeleteX, FremoveX, Fdelete_duplicates, Fremove_duplicates)
(Fnsubstitute, Fsubstitute, Fsublis, Fnsublis, Fsubst, Fnsubst)
(Ftree_equal, Fmismatch, Fsearch, Fintersection, Fnintersection)
(Fsubsetp, Fset_difference, Fnset_difference, Fnunion, Funion)
(Fset_exclusive_or, Fnset_exclusive_or): New, moved here from
cl-seq.el.
(position): New. The implementation of #'find and #'position.
(list_delete_duplicates_from_end, subst, sublis, nsublis)
(tree_equal, mismatch_from_end, mismatch_list_list)
(mismatch_list_string, mismatch_list_array)
(mismatch_string_array, mismatch_string_string)
(mismatch_array_array, get_mismatch_func): Helper C functions for
the Lisp-visible functions.
(venn, nvenn): New. The implementation of the main Lisp functions that
treat lists as sets.
lisp/ChangeLog addition:
2010-12-30 Aidan Kehoe <kehoea@parhasard.net>
* cl-seq.el:
Move the heavy lifting from this file to C. Dump the
cl-parsing-keywords macro, but don't use defun* for the functions
we define that do take keywords, dynamic scope lossage makes that
not practical.
* subr.el (sort, fillarray): Move these aliases here.
(map-plist): #'nsublis is now built-in, but at this point #'eql
isn't necessarily available as a test; use #'eq.
* obsolete.el (cl-delete-duplicates): Make this available for old
compiler macros and old code.
(memql): Document that this is equivalent to #'member*, and worse.
* cl.el (adjoin, subst): Removed. These are in C.

| 54 ;; Change Log: | |
| 55 | |
| 56 ;; Modified 3/7/1991 by Dave Gillespie: | |
| 57 ;; (Author's address: daveg@synaptics.com or daveg@csvax.cs.caltech.edu) | |
| 58 ;; | |
| 59 ;; Added keys: i, t, <, >, [, ], {, }, 6, 7, 8, 9, 0. | |
| 60 ;; Look at help for info-mode (type ? in Info) for descriptions. | |
| 61 ;; | |
| 62 ;; If Info-directory-list is undefined and there is no INFOPATH | |
| 63 ;; in the environment, use value of Info-directory for compatibility | |
| 64 ;; with Emacs 18.57. | |
| 65 ;; | |
| 66 ;; All files named "localdir" found in the path are appended to "dir", | |
| 67 ;; the Info directory. For this to work, "dir" should contain only | |
| 68 ;; one node (Top), and each "localdir" should contain no ^_ or ^L | |
| 69 ;; characters. Generally they will contain only one or several | |
| 70 ;; additional lines for the top-level menu. Note that "dir" is | |
| 71 ;; modified in memory each time it is loaded, but not on disk. | |
| 72 ;; | |
| 73 ;; If "dir" contains a line of the form: "* Locals:" | |
| 74 ;; then the "localdir"s are inserted there instead of at the end. | |
| 75 | |
| 76 | |
| 77 ;; Modified 4/3/1991 by Dave Gillespie: | |
| 78 ;; | |
| 79 ;; Added Info-mode-hook (suggested by Sebastian Kremer). | |
| 80 ;; Also added epoch-info-startup/select-hooks from Simon Spero's info.el. | |
| 81 ;; | |
| 82 ;; Added automatic decoding of compressed Info files. | |
| 83 ;; See documentation for the variable Info-suffix-list. Default is to | |
| 84 ;; run "uncompress" on ".Z" files and "unyabba" on ".Y" files. | |
| 85 ;; (See comp.sources.unix v24i073-076 for yabba/unyabba, a free software | |
| 86 ;; alternative to compress/uncompress.) | |
| 87 ;; Note: "dir" and "localdir" files should not be compressed. | |
| 88 ;; | |
| 89 ;; Changed variables like Info-enable-edit to be settable by M-x set-variable. | |
| 90 ;; | |
| 91 ;; Added Info-auto-advance variable. If t, SPC and DEL will act like | |
| 92 ;; } and {, i.e., they advance to the next/previous node if at the end | |
| 93 ;; of the buffer. | |
| 94 ;; | |
| 95 ;; Changed `u' to restore point to most recent location in that node. | |
| 96 ;; Added `=' to do this manually at any time. (Suggested by David Fox). | |
| 97 ;; | |
| 98 ;; Changed `m' and `0-9' to try interpreting menu name as a file name | |
| 99 ;; if not found as a node name. This allows (dir) menus of the form, | |
| 100 ;; Emacs:: Cool text editor | |
| 101 ;; as a shorthand for | |
| 102 ;; Emacs:(emacs). Cool text editor | |
| 103 ;; | |
| 104 ;; Enhanced `i' to use line-number information in the index. | |
| 105 ;; Added `,' to move among all matches to a previous `i' command. | |
| 106 ;; | |
| 107 ;; Added `a' (Info-annotate) for adding personal notes to any Info node. | |
| 108 ;; Notes are not stored in the actual Info files, but in the user's own | |
| 109 ;; ~/.infonotes file. | |
| 110 ;; | |
| 111 ;; Added Info-footnote-tag, made default be "Ref" instead of "Note". | |
| 112 ;; | |
| 113 ;; Got mouse-click stuff to work under Emacs version 18. Check it out! | |
| 114 ;; Left and right clicks scroll the Info window. | |
| 115 ;; Middle click goes to clicked-on node, e.g., "Next:", a menu, or a note. | |
| 116 | |
| 117 | |
| 118 ;; Modified 6/29/1991 by Dave Gillespie: | |
| 119 ;; | |
| 120 ;; Renamed epoch-info-startup/select-hooks to Info-startup/select-hook. | |
| 121 ;; | |
| 122 ;; Made Info-select-node into a command on the `!' key. | |
| 123 ;; | |
| 124 ;; Added Info-mouse-support user option. | |
| 125 ;; | |
| 126 ;; Cleaned up the implementation of some routines. | |
| 127 ;; | |
| 128 ;; Added special treatment of quoted words in annotations: The `g' | |
| 129 ;; command for a nonexistent node name scans for an annotation | |
| 130 ;; (in any node of any file) containing that name in quotes: g foo RET | |
| 131 ;; looks for an annotation containing: "foo" or: <<foo>> | |
| 132 ;; If found, it goes to that file and node. | |
| 133 ;; | |
| 134 ;; Added a call to set up Info-directory-list in Info-find-node to | |
| 135 ;; work around a bug in GNUS where it calls Info-goto-node before info. | |
| 136 ;; | |
| 137 ;; Added completion for `g' command (inspired by Richard Kim's infox.el). | |
| 138 ;; Completion knows all node names for the current file, and all annotation | |
| 139 ;; tags (see above). It does not complete file names or node names in | |
| 140 ;; other files. | |
| 141 ;; | |
| 142 ;; Added `k' (Info-emacs-key) and `*' (Info-elisp-ref) commands. You may | |
| 143 ;; wish to bind these to global keys outside of Info mode. | |
| 144 ;; | |
| 145 ;; Allowed localdir files to be full dir-like files; only the menu part | |
| 146 ;; of each localdir is copied. Also, redundant menu items are omitted. | |
| 147 ;; | |
| 148 ;; Changed Info-history to hold only one entry at a time for each node, | |
| 149 ;; and to be circular so that multiple `l's come back again to the most | |
| 150 ;; recent node. Note that the format of Info-history entries has changed, | |
| 151 ;; which may interfere with external programs that try to operate on it. | |
| 152 ;; (Also inspired by Kim's infox.el). | |
| 153 ;; | |
| 154 ;; Changed `n', `]', `l', etc. to accept prefix arguments to move several | |
| 155 ;; steps at once. Most accept negative arguments to move oppositely. | |
| 156 ;; | |
| 157 ;; Changed `?' to bury *Help* buffer afterwards to keep it out of the way. | |
| 158 ;; | |
| 159 ;; Rearranged `?' key's display to be a little better for new users. | |
| 160 ;; | |
| 161 ;; Changed `a' to save whole window configuration and restore on C-c C-c. | |
| 162 ;; | |
| 163 ;; Fixed the bug reported by Bill Reynolds on gnu.emacs.bugs. | |
| 164 ;; | |
| 165 ;; Changed Info-last to restore window-start as well as cursor position. | |
| 166 ;; | |
| 167 ;; Changed middle mouse button in space after end of node to do Info-last | |
| 168 ;; if we got here by following a cross reference, else do Info-global-next. | |
| 169 ;; | |
| 170 ;; Added some new mouse bindings: shift-left = Info-global-next, | |
| 171 ;; shift-right = Info-global-prev, shift-middle = Info-last. | |
| 172 ;; | |
| 173 ;; Fixed Info-follow-reference not to make assumptions about length | |
| 174 ;; of Info-footnote-tag [Linus Tolke]. | |
| 175 ;; | |
| 176 ;; Changed default for Info-auto-advance mode to be press-twice-for-next-node. | |
| 177 ;; | |
| 178 ;; Modified x-mouse-ignore to preserve last-command variable, so that | |
| 179 ;; press-twice Info-auto-advance mode works with the mouse. | |
| 180 | |
| 181 | |
| 182 ;; Modified 3/4/1992 by Dave Gillespie: | |
| 183 ;; | |
| 184 ;; Added an "autoload" command to help autoload.el. | |
| 185 ;; | |
| 186 ;; Changed `*' command to look for file `elisp' as well as for `lispref'. | |
| 187 ;; | |
| 188 ;; Fixed a bug involving footnote names containing regexp special characters. | |
| 189 ;; | |
| 190 ;; Fixed a bug in completion during `f' (or `r') command. | |
| 191 ;; | |
| 192 ;; Added TAB (Info-next-reference), M-TAB, and RET keys to Info mode. | |
| 193 ;; | |
| 194 ;; Added new bindings, `C-h C-k' for Info-emacs-key and `C-h C-f' for | |
| 195 ;; Info-elisp-ref. These bindings are made when info.el is loaded, and | |
| 196 ;; only if those key sequences were previously unbound. These bindings | |
| 197 ;; work at any time, not just when Info is already running. | |
| 198 | |
| 199 | |
| 200 ;; Modified 3/8/1992 by Dave Gillespie: | |
| 201 ;; | |
| 202 ;; Fixed some long lines that were causing trouble with mailers. | |
| 203 | |
| 204 | |
| 205 ;; Modified 3/9/1992 by Dave Gillespie: | |
| 206 ;; | |
| 207 ;; Added `C-h C-i' (Info-query). | |
| 208 ;; | |
| 209 ;; Added Info-novice mode, warns if the user attempts to switch to | |
| 210 ;; a different Info file. | |
| 211 ;; | |
| 212 ;; Fixed a bug that caused problems using compressed Info files | |
| 213 ;; and Info-directory-list at the same time. | |
| 214 ;; | |
| 215 ;; Disabled Info-mouse-support by default if Epoch or Hyperbole is in use. | |
| 216 ;; | |
| 217 ;; Added an expand-file-name call to Info-find-node to fix a small bug. | |
| 218 | |
| 219 | |
| 220 ;; Modified 5/22/1992 by Dave Gillespie: | |
| 221 ;; | |
| 222 ;; Added "standalone" operation: "emacs -f info" runs Emacs specifically | |
| 223 ;; for use as an Info browser. In this mode, the `q' key quits Emacs | |
| 224 ;; itself. Also, "emacs -f info arg" starts in Info file "arg" instead | |
| 225 ;; of "dir". | |
| 226 ;; | |
| 227 ;; Changed to prefer "foo.info" over "foo". If both exist, "foo" is | |
| 228 ;; probably a directory or executable program! | |
| 229 ;; | |
| 230 ;; Made control-mouse act like regular-mouse does in other buffers. | |
| 231 ;; (In most systems, this will be set-cursor for left-mouse, x-cut | |
| 232 ;; for right-mouse, and x-paste, which will be an error, for | |
| 233 ;; middle-mouse.) | |
| 234 ;; | |
| 235 ;; Improved prompting and searching for `,' key. | |
| 236 ;; | |
| 237 ;; Fixed a bug where some "* Menu:" lines disappeared when "dir" | |
| 238 ;; contained several nodes. | |
| 239 | |
| 240 | |
| 241 ;; Modified 9/10/1992 by Dave Gillespie: | |
| 242 ;; | |
| 243 ;; Mixed in support for XEmacs. Mouse works the same as in | |
| 244 ;; the other Emacs versions by default; added Info-lucid-mouse-style | |
| 245 ;; variable, which enables mouse operation similar to XEmacs's default. | |
| 246 ;; | |
| 247 ;; Fixed a bug where RET couldn't understand "* Foo::" if "Foo" was a | |
| 248 ;; file name instead of a node name. | |
| 249 ;; | |
| 250 ;; Added `x' (Info-bookmark), a simple interface to the annotation | |
| 251 ;; tags feature. Added `j' (Info-goto-bookmark), like `g' but only | |
| 252 ;; completes bookmarks. | |
| 253 ;; | |
| 254 ;; Added `<<tag>>' as alternate to `"tag"' in annotations. | |
| 255 ;; | |
| 256 ;; Added `v' (Info-visit-file), like Info-goto-node but specialized | |
| 257 ;; for going to a new Info file (with file name completion). | |
| 258 ;; | |
| 259 ;; Added recognition of gzip'd ".z" files. | |
| 260 | |
| 261 | |
| 262 ;; Modified 5/9/1993 by Dave Gillespie: | |
| 263 ;; | |
| 264 ;; Merged in various things from FSF's latest Emacs 19 info.el. | |
| 265 | |
| 266 ;; Modified 6/2/1993 by Dave Gillespie: | |
| 267 ;; | |
| 268 ;; Changed to use new suffix ".gz" for gzip files. | |
| 269 | |
| 270 | |
| 271 ;; Modified 7/22/1993 by Dave Gillespie: | |
| 272 ;; | |
| 273 ;; Changed Info-footnote-tag to "See" instead of "Ref". | |
| 274 ;; | |
| 275 ;; Extended Info-fontify-node to work with FSF version of Emacs 19. | |
| 276 | |
| 277 ;; Modified 7/30/1993 by Jamie Zawinski: | |
| 278 ;; | |
| 279 ;; Commented out the tty and fsf19 mouse support, because why bother. | |
| 280 ;; Commented out the politically incorrect version of XEmacs mouse support. | |
| 281 ;; Commented out mouse scrolling bindings because the party line on that | |
| 282 ;; is "scrollbars are coming soon." | |
| 283 ;; Commented out munging of help-for-help's doc; put it in help.el. | |
| 284 ;; Did Info-edit-map the modern XEmacs way. | |
| 285 ;; Pruned extra cruft from fontification and mouse handling code. | |
| 286 ;; Fixed ASCII-centric bogosity in unreading of events. | |
| 287 | |
| 288 ;; Modified 8/11/95 by Chuck Thompson: | |
| 289 ;; | |
| 290 ;; Removed any pretense of ever referencing Info-directory since it | |
| 291 ;; wasn't working anyhow. | |
| 292 | |
| 293 ;; Modified 4/5/97 by Tomasz J. Cholewo: | |
| 294 ;; | |
| 295 ;; Modified Info-search to use with-caps-disable-folding | |
| 296 | |
| 297 ;; Modified 6/21/97 by Hrvoje Niksic | |
| 298 ;; | |
| 299 ;; Fixed up Info-next-reference to work sanely when n < 0. | |
| 300 ;; Added S-tab binding. | |
| 301 | |
| 302 ;; Modified 1997-07-10 by Karl M. Hegbloom | |
| 303 ;; | |
| 304 ;; Added `Info-minibuffer-history' | |
| 305 ;; (also added to defaults in "lisp/utils/savehist.el") | |
| 306 ;; Other changes in main ChangeLog. | |
| 307 | |
| 308 ;; Modified 1998-03-29 by Oscar Figueiredo | |
| 309 ;; | |
| 310 ;; Added automatic dir/localdir (re)building capability for directories that | |
| 311 ;; contain none or when it has become older than info files in the same | |
| 312 ;; directory. | |
