Support the MP library on recent FreeBSD, have it pass relevant tests.
src/ChangeLog addition:
2011-11-26 Aidan Kehoe <kehoea@parhasard.net>
* number-mp.c (bignum_to_string):
Don't overwrite the accumulator we've just set up for this
function.
* number-mp.c (BIGNUM_TO_TYPE):
mp_itom() doesn't necessarily do what this code used to think with
negative numbers, it can treat them as unsigned ints. Subtract
numbers from bignum_zero instead of multiplying them by -1 to
convert them to their negative equivalents.
* number-mp.c (bignum_to_int):
* number-mp.c (bignum_to_uint):
* number-mp.c (bignum_to_long):
* number-mp.c (bignum_to_ulong):
* number-mp.c (bignum_to_double):
Use the changed BIGNUM_TO_TYPE() in these functions.
* number-mp.c (bignum_ceil):
* number-mp.c (bignum_floor):
In these functions, be more careful about rounding to positive and
negative infinity, respectively. Don't use the sign of QUOTIENT
when working out out whether to add or subtract one, rather use
the sign QUOTIENT would have if arbitrary-precision division were
done.
* number-mp.h:
* number-mp.h (MP_GCD):
Wrap #include <mp.h> in BEGIN_C_DECLS/END_C_DECLS.
* number.c (Fbigfloat_get_precision):
* number.c (Fbigfloat_set_precision):
Don't attempt to call XBIGFLOAT_GET_PREC if this build doesn't
support big floats.

| 21 * Changes in XEmacs 20.4 | |
| 22 ======================== | |
| 23 | |
| 24 ** XEmacs 20.4 is a bugfix release with no user-visible changes. | |
| 25 | |
| 26 | |
| 27 * Changes in XEmacs 20.3 | |
| 28 ======================== | |
| 29 | |
| 30 ** Quail input method is now available. | |
| 31 | |
| 32 Quail is a simple key-translation system that allows users to input | |
| 33 any multilingual text from normal ASCII keyboard. This means that | |
| 34 XEmacs with Mule now supports a number of European languages. | |
| 35 | |
| 36 ** More Windows NT support. | |
| 37 | |
| 38 Thanks to efforts of many people, coordinated by David Hobley | |
| 39 <davidh@wr.com.au> and Marc Paquette <marcpa@cam.org>, beta versions | |
| 40 of XEmacs now run on 32-bit Windows platforms (Windows NT and Windows | |
| 41 95). The current betas require having an X server to run XEmacs; | |
| 42 however, a native NT/95 port is in alpha, thanks to Jonathan Harris | |
| 43 <jhar@tardis.ed.ac.uk>. | |
| 44 | |
| 45 The NT development is now coordinated by a mailing list at | |
| 46 <xemacs-nt@xemacs.org>. Mail to <xemacs-nt-request@xemacs.org> to | |
| 47 subscribe. | |
| 48 | |
| 49 ** Multiple TTY frames are now available. | |
| 50 | |
| 51 On consoles that display only one frame at a time (e.g. TTY consoles), | |
| 52 creating a new frame with `C-x 5 2' also raises and selects that | |
| 53 frame. The behavior of window system frames is unchanged. | |
| 54 | |
| 55 ** Package starting changes. | |
| 56 | |
| 57 State of Emacs should never be changed with loading a package. The | |
| 58 following XEmacs packages that used to break this have been changed. | |
| 59 | |
| 60 *** Loading `paren' no longer enables paren-blinking. Use | |
| 61 `paren-set-mode' explicitly, or customize `paren-mode'. | |
| 62 | |
| 63 *** Loading `uniquify' no longer enables uniquify. Set | |
| 64 `uniquify-buffer-name-style' to a legal value. | |
| 65 | |
| 66 *** Loading `time' no longer enables display time. Invoke | |
| 67 `display-time' explicitly. | |
| 68 | |
| 69 *** Loading `jka-compr' no longer enables on-the-fly compression. Use | |
| 70 `toggle-auto-compression' instead. | |
| 71 | |
| 72 *** Loading `id-select' no longer enables its behaviour. Use | |
| 73 `id-select-install' instead. | |
| 74 | |
| 75 ** Zmacs region is not deactivated when an error is signaled. | |
| 76 | |
| 77 The behavior of the zmacs region can now be controlled in the event of | |
| 78 a signaled error. The new variable `errors-deactivate-region' may be | |
| 79 set to nil to revert to the old behaviour. As before, typing C-g | |
| 80 deactivates the region. | |
| 81 | |
| 82 ** Multiple Info `dir' functionality has been merged with GNU Emacs | |
| 83 19.34. | |
| 84 | |
| 85 XEmacs will now correctly merge all the `dir' files in | |
| 86 `Info-directory-list' (initialized from either the `INFOPATH' | |
| 87 env. variable or `Info-default-directory-list'.) These files may be | |
| 88 full-fledged info files containing subnodes or menus. Previously | |
| 89 supported `localdir' files are looked for also, secondary to `dir's. | |
| 90 See the manual for details. | |
| 91 | |
| 92 ** Abbreviations can now contain non-word characters. | |
| 93 | |
| 94 This means that it is finally possible to do such simple things as | |
| 95 define `#in' to expand to `#include' in C mode, `s-c-b' to | |
| 96 `save-current-buffer' in Lisp mode, `call/cc' to | |
| 97 `call-with-current-continuation' in Scheme mode, etc. | |
| 98 | |
| 99 ** `C-x n d' now runs the new command `narrow-to-defun', | |
| 100 which narrows the accessible parts of the buffer to just | |
| 101 the current defun. | |
| 102 | |
| 103 ** The new command `C-x 4 0' (kill-buffer-and-window) kills the | |
| 104 current buffer and deletes the selected window. It asks for | |
| 105 confirmation first. | |
| 106 | |
| 107 ** `ESC ESC ESC' (keyboard-escape-quit) will now correctly abort | |
| 108 recursive edits (as documented.) | |
| 109 | |
| 110 ** arc-mode has a new function called `archive-quit' bound to q, which | |
| 111 quits archive mode in the same fashion dired-quit works. | |
| 112 | |
| 113 ** A `tetris' clone is now available within XEmacs, written by Glynn | |
| 114 Clements. Try it out with `M-x tetris'. | |
| 115 | |
| 116 ** The feature to teach the key bindings of extended commands now | |
| 117 prints the message after the command finishes. After some time, the | |
| 118 previous echo area contents are restored (in case the command prints | |
| 119 something useful). | |
| 120 | |
| 121 ** If you set scroll-conservatively to a small number, then when you | |
| 122 move point a short distance off the screen, XEmacs will scroll the | |
| 123 screen just far enough to bring point back on screen, provided that | |
| 124 does not exceed `scroll-conservatively' lines. | |
| 125 | |
| 126 ** Face background colors now take precedence over the default face | |
| 127 background pixmap, which means that background pixmaps no longer clash | |
| 128 with zmacs-regions, or clickable buttons. | |
| 129 | |
| 130 ** Regexps can now contain additional Perl-like constructs. | |
| 131 | |
| 132 ** Modifiers can be added to a keystroke by preceding it with a `C-x @ | |
| 133 <x>' sequence where <x> is one of letters `S', `c', `m', `a', `h', `s' | |
| 134 corresponding to shift, control, meta, alt, hyper, and super modifiers, | |
| 135 respectively. It is possible to add several modifiers by repeating this | |
| 136 sequence. This feature is especially useful on text terminals where it | |
| 137 allows one to enter keystrokes like, e.g., `M-home'. | |
| 138 | |
| 139 ** An arbitrary keystroke can be generated by entering `C-x @ k | |
| 140 <keysym-name> RET'. For example a sequence: | |
| 141 | |
| 142 C-x @ c C-x @ k b a c k s p a c e RET | |
| 143 | |
| 144 will result in a `C-backspace' keystroke even on text terminals. | |
| 145 | |
| 146 ** Customize changes. | |
| 147 | |
| 148 *** Customize has undergone a massive speedup, and should now operate | |
| 149 acceptably fast. Slowness of the interface used to be the biggest | |
| 150 gripe. | |
| 151 | |
| 152 *** Many more packages have been modified to use the facility, so | |
| 153 almost all of XEmacs options can now be examined through the Customize | |
| 154 groups. | |
| 155 | |
| 156 *** There is a new `browser' mode of traversing customizations, in | |
| 157 many ways easier to follow than the standard one. Try it out with | |
| 158 `M-x customize-browse'. | |
| 159 | |
| 160 ** Pending-delete changes. | |
| 161 | |
| 162 *** Pending-delete is now a minor mode, with the normal minor-mode | |
| 163 semantics and toggle functions. Old functions are left for | |
| 164 compatibility. | |
| 165 | |
| 166 *** Loading pending-del no longer turns on pending-delete mode. In | |
| 167 fact, it is no longer necessary to explicitly load pending-del. All | |
| 168 you need to do to turn on pending-delete is run the pending-delete | |
| 169 function: | |
| 170 | |
| 171 Within XEmacs: Type M-x pending-delete <ret> | |
| 172 not M-x load-library <ret> pending-delete <ret> | |
| 173 | |
| 174 In .emacs: Use (turn-on-pending-delete) | |
| 175 not (load "pending-del") | |
| 176 | |
| 177 ** XEmacs can now save the minibuffer histories from various | |
| 178 minibuffers. To use this feature, add the line: | |
| 179 | |
| 180 (savehist-load) | |
| 181 | |
| 182 to your .emacs. This will load the minibuffer histories (if any) at | |
| 183 startup, as well as instruct XEmacs to save them before exiting. You | |
| 184 can use Customize to add or remove the histories being saved. | |
| 185 | |
| 186 ** The default format for ChangeLog entries (as created by `C-x 4 a') | |
| 187 is now the international ISO 8601 format. | |
| 188 | |
| 189 To revert to the old behaviour, use: | |
| 190 | |
| 191 (setq add-log-time-format 'current-time-string) | |
| 192 | |
| 193 Or `M-x customize RET add-log RET'. | |
| 194 | |
| 195 ** In ChangeLog mode, you can now press `C-c C-c' to save the file | |
| 196 and restore old window configuration, or `C-c C-k' to abandon the | |
| 197 changes. | |
| 198 | |
| 199 ** The key `C-x m' no longer runs the `mail' command directly. | |
| 200 Instead, it runs the command `compose-mail', which invokes the mail | |
| 201 composition mechanism you have selected with the variable | |
| 202 `mail-user-agent'. The default choice of user agent is | |
| 203 `sendmail-user-agent', which gives behavior compatible with the old | |
| 204 behavior. | |
| 205 | |
| 206 C-x 4 m now runs compose-mail-other-window, and C-x 5 m runs | |
| 207 compose-mail-other-frame. | |
| 208 | |
| 209 ** When you kill a buffer that visits a file, if there are any | |
| 210 registers that save positions in the file, these register values no | |
| 211 longer become completely useless. If you try to go to such a register | |
| 212 with `C-x j', then you are asked whether to visit the file again. If | |
| 213 you say yes, it visits the file and then goes to the same position. | |
| 214 | |
| 215 ** When you visit a file that changes frequently outside Emacs--for | |
| 216 example, a log of output from a process that continues to run--it may | |
| 217 be useful for Emacs to revert the file without querying you whenever | |
| 218 you visit the file afresh with `C-x C-f'. | |
| 219 | |
| 220 You can request this behavior for certain files by setting the | |
| 221 variable revert-without-query to a list of regular expressions. If a | |
| 222 file's name matches any of these regular expressions, find-file and | |
| 223 revert-buffer revert the buffer without asking for permission--but | |
| 224 only if you have not edited the buffer text yourself. | |
| 225 | |
| 226 ** Gnuserv changes | |
| 227 | |
| 228 *** The Lisp part of gnuserv has been rewritten to allow for more | |
| 229 flexibility and features. | |
| 230 | |
| 231 *** Many new options and variables are now customizable. Try | |
| 232 `M-x customize RET gnuserv RET'. | |
| 233 | |
| 234 *** The functionality of `gnuattach' and `gnudoit' programs is | |
| 235 provided by `gnuclient', which now accepts the standard `-nw', | |
| 236 `-display', `-eval' and `-f' options. | |
| 237 | |
| 238 ** Etags changes. | |
| 239 | |
| 240 *** In C, C++, Objective C and Java, Etags tags global variables by | |
| 241 default. The resulting tags files are inflated by 30% on average. | |
| 242 Use --no-globals to turn this feature off. Etags can also tag | |
| 243 variables that are members of structure-like constructs, but it does | |
| 244 not by default. Use --members to turn this feature on. | |
| 245 | |
| 246 *** C++ member functions are now recognized as tags. | |
| 247 | |
| 248 *** Java is tagged like C++. In addition, "extends" and "implements" | |
| 249 constructs are tagged. Files are recognised by the extension .java. | |
| 250 | |
| 251 *** Etags can now handle programs written in Postscript. Files are | |
| 252 recognised by the extensions .ps and .pdb (Postscript with C syntax). | |
| 253 In Postscript, tags are lines that start with a slash. | |
| 254 | |
| 255 *** Etags now handles Objective C and Objective C++ code. The usual C and | |
| 256 C++ tags are recognized in these languages; in addition, etags | |
| 257 recognizes special Objective C syntax for classes, class categories, | |
| 258 methods and protocols. | |
| 259 | |
| 260 *** Etags also handles Cobol. Files are recognised by the extension | |
| 261 .cobol. The tagged lines are those containing a word that begins in | |
| 262 column 8 and ends in a full stop, i.e. anything that could be a | |
| 263 paragraph name. | |
| 264 | |
| 265 *** Regexps in Etags now support intervals, as in ed or grep. The syntax of | |
| 266 an interval is \{M,N\}, and it means to match the preceding expression | |
| 267 at least M times and as many as N times. | |
| 268 | |
| 269 ** Ada mode changes. | |
| 270 | |
| 271 *** There is now better support for using find-file.el with Ada mode. | |
| 272 If you switch between spec and body, the cursor stays in the same | |
| 273 procedure (modulo overloading). If a spec has no body file yet, but | |
| 274 you try to switch to its body file, Ada mode now generates procedure | |
| 275 stubs. | |
| 276 | |
| 277 *** There are two new commands: | |
| 278 - `ada-make-local' : invokes gnatmake on the current buffer | |
| 279 - `ada-check-syntax' : check syntax of current buffer. | |
| 280 | |
| 281 The user options `ada-compiler-make', `ada-make-options', | |
| 282 `ada-language-version', `ada-compiler-syntax-check', and | |
| 283 `ada-compile-options' are used within these commands. | |
| 284 | |
| 285 *** Ada mode can now work with Outline minor mode. The outline level | |
| 286 is calculated from the indenting, not from syntactic constructs. | |
| 287 Outlining does not work if your code is not correctly indented. | |
| 288 | |
| 289 *** The new function `ada-gnat-style' converts the buffer to the style of | |
| 290 formatting used in GNAT. It places two blanks after a comment start, | |
| 291 places one blank between a word end and an opening '(', and puts one | |
| 292 space between a comma and the beginning of a word. | |
| 293 | |
| 294 ** New demand based locking implementation | |
| 295 | |
| 296 A faster, but experimental replacement for lazy-lock (called lazy-shot) is | |
| 297 provided. Like lazy-lock it provides demand based and idle time | |
| 298 font-lock-ing. However the lazy-lock versions that came with previous | |
| 299 versions slowed down XEmacs (possibly quite a lot). Lazy-shot solves | |
| 300 this problem by relying on new support from the C code part of XEmacs. | |
| 301 The support however is experimental and will cause some flashing as | |
| 302 parts of the buffer are colored. This likely to change in the future | |
| 303 as the C support is completed. | |
| 304 | |
| 305 The current lazy-shot implementation is mostly interface compatible | |
| 306 with lazy-lock v2.06 (the version shipped with XEmacs is v1.x). | |
| 307 | |
| 308 *** To enable: | |
| 309 1. Despite the flashing, lazy-shot was deemed such an improvement by | |
| 310 the majority of beta testers that it is now the standard method | |
| 311 provided by the options menu. Alternatively add | |
| 312 | |
| 313 (add-hook 'font-lock-mode-hook 'turn-on-lazy-shot) | |
| 314 | |
| 315 to '.emacs'. | |
| 316 2. If you were using lazy-lock before, just replace all occurrences of | |
| 317 "lazy-lock" by "lazy-shot" in your '.emacs' file. | |
| 318 | |
| 319 *** To disable: | |
| 320 | |
| 321 If prefer to use lazy-lock in stead of lazy-shot, put | |
| 322 | |
| 323 (remove-hook 'font-lock-mode-hook 'turn-on-lazy-shot) | |
| 324 (add-hook 'font-lock-mode-hook 'turn-on-lazy-lock) | |
| 325 | |
| 326 at the END of `.emacs'. | |
| 327 | |
| 328 ** RefTeX mode | |
| 329 | |
| 330 RefTeX mode is a new minor mode with special support for \label{}, \ref{} | |
| 331 and \cite{} macros in LaTeX documents. RefTeX distinguishes labels of | |
| 332 different environments (equation, figure, ...) and has full support for | |
| 333 multifile documents. To use it, select a buffer with a LaTeX document and | |
| 334 turn the mode on with M-x reftex-mode. Here are the main user commands: | |
| 335 | |
| 336 C-c ( reftex-label | |
| 337 Creates a label semi-automatically. RefTeX is context sensitive and | |
| 338 knows which kind of label is needed. | |
| 339 | |
| 340 C-c ) reftex-reference | |
| 341 Offers in a menu all labels in the document, along with context of the | |
| 342 label definition. The selected label is referenced as \ref{LABEL}. | |
| 343 | |
| 344 C-c [ reftex-citation | |
| 345 Prompts for a regular expression and displays a list of matching BibTeX | |
| 346 database entries. The selected entry is cited with a \cite{KEY} macro. | |
| 347 | |
| 348 C-c & reftex-view-crossref | |
| 349 Views the cross reference of a \ref{} or \cite{} command near point. | |
| 350 | |
| 351 C-c = reftex-toc | |
| 352 Shows a table of contents of the (multifile) document. From there you | |
| 353 can quickly jump to every section. | |
| 354 | |
| 355 Under X, RefTeX installs a "Ref" menu in the menu bar, with additional | |
| 356 commands. Full documentation and customization examples are in the file | |
| 357 reftex.el. You can use the finder to view this information: | |

| 361 * Lisp and internal changes in XEmacs 20.3 | |
| 362 ========================================== | |
| 363 | |
| 364 ** Autoconf 2 is supported, making XEmacs more conforming to | |
| 365 conventions used by other free software. | |
| 366 | |
| 367 ** `tty-erase-char' is a new variable that reports which character | |
| 368 was set up as the terminal's erase character at the time Emacs was | |
| 369 started. | |
| 370 | |
| 371 ** It is now possible to attach the menubar accelerator keys to menu | |
| 372 entries. Look at the Lispref under Menus->Menu Accelerators for | |
| 373 details. | |
| 374 | |
| 375 ** `insert-file-contents' can now read from a special file, | |
| 376 as long as the arguments VISIT and REPLACE are nil. | |
| 377 | |
| 378 ** `string-to-number' now accepts an optional BASE argument that | |
| 379 specifies which base to use. The default base is 10. | |
| 380 | |
| 381 ** The TIME argument to `format-time-string' is now optional and | |
| 382 defaults to the current time. | |
| 383 | |
| 384 ** The PATTERN argument to `split-string' is now optional and defaults | |
| 385 to whitespace ("[ \f\t\n\r\v]+"). | |
| 386 | |
| 387 ** `set-extent-properties' is a new function that can be used to | |
| 388 change properties of an extent at once, and is analogous to | |
| 389 `set-frame-properties'. | |
| 390 | |
| 391 ** If a format field width is specified as `*', the field width is | |
| 392 now assumed to have been specified as an argument (as in C.) | |
| 393 | |
| 394 (format "%*s" 10 "abc") | |
| 395 => " abc" | |
| 396 | |
| 397 ** The new macro `with-current-buffer' lets you evaluate an expression | |
| 398 conveniently with a different current buffer. It looks like this: | |
| 399 | |
| 400 (with-current-buffer BUFFER BODY-FORMS...) | |
| 401 | |
| 402 BUFFER is the expression that says which buffer to use. | |
| 403 BODY-FORMS say what to do in that buffer. | |
| 404 The old `eval-in-buffer' macro is obsoleted by `with-current-buffer'. | |
| 405 | |
| 406 ** The new primitive `save-current-buffer' saves and restores the | |
| 407 choice of current buffer, like `save-excursion', but without saving or | |
| 408 restoring the value of point or the mark. `with-current-buffer' | |
| 409 works using `save-current-buffer'. | |
| 410 | |
| 411 ** The new macro `with-temp-file' lets you do some work in a new buffer and | |
| 412 write the output to a specified file. Like `progn', it returns the value | |
| 413 of the last form. | |
| 414 | |
| 415 ** The variable `debug-ignored-errors' now works in XEmacs. It allows | |
| 416 one to ignore the debugger for some common errors, even when | |
| 417 `debug-on-error' is t. It has no effect when `debug-on-signal' is | |
| 418 non-nil. | |
| 419 | |
| 420 ** The new function `current-message' returns the message currently | |
| 421 displayed in the echo area, or nil if there is none. | |
| 422 | |
| 423 ** File-access primitive functions no longer discard an extra redundant | |
| 424 directory name from the beginning of the file name. In other words, | |
| 425 they no longer do anything special with // or /~. The same goes for | |
| 426 `expand-file-name'. That conversion is now done only in | |
| 427 `substitute-in-file-name'. | |
| 428 | |
| 429 This makes it possible for a Lisp program to open a file whose name | |
| 430 begins with ~. | |
| 431 | |
| 432 ** The regexp matcher has been extended to recognize the following | |
| 433 constructs, borrowed from Perl: | |
| 434 | |
| 435 *** Additional quantifiers. | |
| 436 | |
| 437 In addition to `*', `+' and `?', XEmacs now recognizes the following | |
| 438 quantifiers: | |
| 439 | |
| 440 \{n\} Match exactly n times | |
| 441 \{n,\} Match at least n times | |
| 442 \{n,m\} Match at least n but not more than m times | |
| 443 | |
| 444 *** Non-greedy quantifiers. | |
| 445 | |
| 446 Any of the standard quantifiers (`*', `+' and others) can now be | |
| 447 followed by an optional `?', which will make them become "non-greedy", | |
| 448 i.e. they will match as little text as possible. Note that the | |
| 449 meanings don't change, just the "gravity." | |
| 450 | |
| 451 *** Shy groups. | |
| 452 | |
| 453 The \(?: ... \) groups things like \( ... \), but doesn't record the | |
| 454 context for backreferences or future use. This is useful when you | |
| 455 need a lot of groups for the sake of priorities, but actually want to | |
| 456 record only one or two. | |
| 457 | |
| 458 ** The new function `regexp-opt' returns an efficient regexp to match | |
| 459 a string. The arguments are STRINGS and (optionally) PAREN. This | |
| 460 function can be used where regexp matching or searching is intensively | |
| 461 used and speed is important, e.g., in Font Lock mode. | |
| 462 | |
| 463 ** The featurep syntax has been extended to resemble the Common Lisp | |
| 464 one, as suggested by Erik Naggum. | |
| 465 | |
| 466 *** The `xemacs' feature is defined in XEmacs by default. | |
| 467 | |
| 468 *** The expression `#+fexp form' is equivalent to | |
| 469 (when (featurep fexp) form), only it is evaluated at read-time. Also, | |
| 470 `#-fexp form' is equivalent to (unless (featurep fexp) form). | |
| 471 | |
| 472 *** In addition to symbols, a FEXP can also be a number, or a logical | |
| 473 operator. Here are some examples: | |
| 474 ;; evaluates to non-nil on XEmacs: | |
| 475 (featurep 'xemacs) | |
| 476 ;; evaluates to non-nil on XEmacs 20.3 or later: | |
| 477 (featurep '(and xemacs 20.03)) | |
| 478 ;; evaluates to non-nil either on Emacs, or on XEmacs built without | |
| 479 ;; X support: | |
| 480 (featurep '(or emacs (and xemacs (not x)))) | |
| 481 | |
| 482 | |
| 483 | |
| 484 * Changes in XEmacs 20.2 | |
| 485 ======================== | |
| 486 | |
| 487 ** Why XEmacs 20.1 is called 20.2 | |
| 488 | |
| 489 Testing of XEmacs 20.1 revealed a number of showstopping bugs at the | |
| 490 very final moment. Instead of confusing the version numbers further, | |
| 491 the `20.1' designation was abandoned, and the release was renamed to | |
| 492 `20.2'. | |
| 493 | |
| 494 ** Delete/backspace keysyms have been separated | |
| 495 | |
| 496 The Delete and Backspace keysyms are now no longer identical. A better | |
| 497 version of delbackspace.el has been added called delbs.el. | |
| 498 | |
| 499 ** XEmacs 20.0 MULE API supported for backwards compatibility | |
| 500 | |
| 501 XEmacs 20.2 primarily supports the MULE 3 API. It now also supports | |
| 502 the XEmacs 20.0 MULE API. | |
| 503 | |
| 504 ** The logo has been changed, and the default background color is | |
| 505 now a shade of gray instead of the eye-burning white. | |
| 506 | |
| 507 The sample .Xdefaults and .emacs files contain examples of how to | |
| 508 revert to the old background color. | |
| 509 | |
| 510 ** Default modeline colors are now less of a color-salad. | |
| 511 | |
| 512 ** The `C-z' key now iconifies only the current X frame. You can use | |
| 513 `C-x C-z' to get the old behavior. | |
| 514 | |
| 515 On the tty frames `C-z' behaves as before. | |
| 516 | |
| 517 ** The command `display-time' now draws a pretty image in the modeline | |
| 518 when new mail arrives. It also supports balloon-help messages. | |
| 519 | |
| 520 ** Various commands that were previously disabled are now enabled, like | |
| 521 eval-expression (`M-:') and upcase-region (`C-x C-u')/downcase-region | |
| 522 (`C-x C-l'). | |
| 523 | |
| 524 ** It is now possible to customize the functions called by XEmacs toolbar. | |
| 525 | |
| 526 Type `M-x customize RET toolbar RET' to customize it. Customizations | |
| 527 include the choice of functions for the buttons to invoke, as well as | |
| 528 a wide choice of mailers and newsreaders to invoked by the respective | |
| 529 functions. | |
| 530 | |
| 531 ** `temp-buffer-shrink-to-fit' now defaults to nil. | |
| 532 | |
| 533 There are unresolved issues regarding this feature, which is why the | |
| 534 XEmacs developers decided to disable it by default. | |
| 535 | |
| 536 ** `ps-print-color-p' now defaults to nil. | |
| 537 | |
| 538 This is because the new default background color is non-white. The | |
| 539 `Printing Options' in the `Options' menu now include an item that | |
| 540 enables color printing, and sets the white background. | |
| 541 | |
| 542 ** `line-number-mode' should be used to get line numbers in the | |
| 543 modeline, and `column-number-mode' to get column numbers. Line | |
| 544 numbers now number from 1 by default. | |
| 545 | |
| 546 ** font-lock-mode will now correctly fontify `int a, b, c;' | |
| 547 expressions in C mode. | |
| 548 | |
| 549 ** The blinking cursor is always "on" during movement. | |
| 550 | |
| 551 ** The XEmacs build process has been changed to make site | |
| 552 administration easier. See lisp/site-load.el for details. | |
| 553 | |
| 554 ** Numerous causes of crashes have been fixed. XEmacs should now be | |
| 555 even more stable than before. | |
| 556 | |
| 557 ** configure no longer defaults to using --with-xim=motif if Motif libraries | |
| 558 are linked. | |
| 559 | |
| 560 There are many bugs in the Xlib XIM support in X11R6.3. | |
| 561 | |
| 562 ** A number of new packages are added, and many packages were | |
| 563 updated. | |
| 564 | |
| 565 ** Gnus-5.4.52, courtesy of Lars Magne Ingebrigtsen | |
| 566 | |
| 567 *** nntp.el has been totally rewritten in an asynchronous fashion. | |
| 568 | |
| 569 *** Article prefetching functionality has been moved up into | |
| 570 Gnus. | |
| 571 | |
| 572 *** Scoring can now be performed with logical operators like | |
| 573 `and', `or', `not', and parent redirection. | |
| 574 | |
| 575 *** Article washing status can be displayed in the | |
| 576 article mode line. | |
| 577 | |
| 578 *** gnus.el has been split into many smaller files. | |
| 579 | |
| 580 *** Suppression of duplicate articles based on Message-ID. | |
| 581 | |
| 582 (setq gnus-suppress-duplicates t) | |
| 583 | |
| 584 *** New variables for specifying what score and adapt files | |
| 585 are to be considered home score and adapt files. See | |
| 586 `gnus-home-score-file' and `gnus-home-adapt-files'. | |
| 587 | |
| 588 *** Groups can inherit group parameters from parent topics. | |
| 589 | |
| 590 *** Article editing has been revamped and is now usable. | |
| 591 | |
| 592 *** Signatures can be recognized in more intelligent fashions. | |
| 593 See `gnus-signature-separator' and `gnus-signature-limit'. | |
| 594 | |
| 595 *** Summary pick mode has been made to look more nn-like. | |
| 596 Line numbers are displayed and the `.' command can be | |
| 597 used to pick articles. | |
| 598 | |
| 599 *** Commands for moving the .newsrc.eld from one server to | |
| 600 another have been added. | |
| 601 | |
| 602 `M-x gnus-change-server' | |
| 603 | |
| 604 *** A way to specify that "uninteresting" fields be suppressed when | |
| 605 generating lines in buffers. | |
| 606 | |
| 607 *** Several commands in the group buffer can be undone with | |
| 608 `M-C-_'. | |
| 609 | |
| 610 *** Scoring can be done on words using the new score type `w'. | |
| 611 | |
| 612 *** Adaptive scoring can be done on a Subject word-by-word basis: | |
| 613 | |
| 614 (setq gnus-use-adaptive-scoring '(word)) | |
| 615 | |
| 616 *** Scores can be decayed. | |
| 617 | |
| 618 (setq gnus-decay-scores t) | |
| 619 | |
| 620 *** Scoring can be performed using a regexp on the Date header. The | |
| 621 Date is normalized to compact ISO 8601 format first. | |
| 622 | |
| 623 *** A new command has been added to remove all data on articles from | |
| 624 the native server. | |
| 625 | |
| 626 `M-x gnus-group-clear-data-on-native-groups' | |
| 627 | |
| 628 *** A new command for reading collections of documents | |
| 629 (nndoc with nnvirtual on top) has been added -- `M-C-d'. | |
| 630 | |
| 631 *** Process mark sets can be pushed and popped. | |
| 632 | |
| 633 *** A new mail-to-news backend makes it possible to post | |
| 634 even when the NNTP server doesn't allow posting. | |
| 635 | |
| 636 *** A new backend for reading searches from Web search engines | |
| 637 (DejaNews, Alta Vista, InReference) has been added. | |
| 638 | |
| 639 Use the `G w' command in the group buffer to create such | |
| 640 a group. | |
| 641 | |
| 642 *** Groups inside topics can now be sorted using the standard | |
| 643 sorting functions, and each topic can be sorted independently. | |
| 644 | |
| 645 See the commands under the `T S' submap. | |
| 646 | |
| 647 *** Subsets of the groups can be sorted independently. | |
| 648 | |
| 649 See the commands under the `G P' submap. | |
| 650 | |
| 651 *** Cached articles can be pulled into the groups. | |
| 652 | |
| 653 Use the `Y c' command. | |
| 654 | |
| 655 *** Score files are now applied in a more reliable order. | |
| 656 | |
| 657 *** Reports on where mail messages end up can be generated. | |
| 658 | |
| 659 `M-x nnmail-split-history' | |
| 660 | |
| 661 *** More hooks and functions have been added to remove junk | |
| 662 from incoming mail before saving the mail. | |
| 663 | |
| 664 See `nnmail-prepare-incoming-header-hook'. | |
| 665 | |
| 666 *** The nnml mail backend now understands compressed article files. | |
| 667 | |
| 668 ** Custom 1.86, courtesy of Per Abrahamsen | |
| 669 | |
| 670 The Customize library enables Emacs Lisp programmers to specify types | |
| 671 of their variables, so that the users can customize them. | |
| 672 | |
| 673 Invoke the customizations buffer using the menus (Customize is at the | |
| 674 top of the Options menu), or using commands `M-x customize', | |
| 675 `M-x customize-variable' and `M-x customize-face'. Customize can save | |
| 676 the changed settings to your `.emacs' file. | |
| 677 | |
| 678 Customize is now the preferred way to change XEmacs settings. Tens of | |
| 679 packages have been converted to take advantage of the Customize | |
| 680 features, including Gnus, Message, Supercite, Psgml, Comint, W3, | |
| 681 cc-mode (and many other programming language modes), ispell.el, | |
| 682 ps-print.el, id-select.el, most of the programming language modes, and | |
| 683 many many more. | |
| 684 | |
| 685 See the "Lisp Changes" section later for a short description of why | |
| 686 and how to add custom support to your Lisp packages. Custom is also | |
| 687 documented in the XEmacs info manuals. | |
| 688 | |
| 689 ** W3-3.0.86, courtesy of William Perry | |
| 690 | |
| 691 Version 3 of Emacs/W3, the Emacs World Wide Web browser, has been | |
| 692 included. It is significantly faster than any of the previous | |
| 693 versions, and contains numerous new features. | |
| 694 | |
| 695 ** AUCTeX-9.7k, courtesy of Per Abrahamsen | |
| 696 | |
| 697 AUC TeX is a comprehensive customizable integrated environment for | |
| 698 writing input files for LaTeX using Emacs. | |
| 699 | |
| 700 AUC TeX lets you run TeX/LaTeX and other LaTeX-related tools, such as | |
| 701 a output filters or post processor from inside Emacs. Especially | |
| 702 `running LaTeX' is interesting, as AUC TeX lets you browse through the | |
| 703 errors TeX reported, while it moves the cursor directly to the | |
| 704 reported error, and displays some documentation for that particular | |
| 705 error. This will even work when the document is spread over several | |
| 706 files. | |
| 707 | |
| 708 AUC TeX automatically indents your `LaTeX-source', not only as you | |
| 709 write it -- you can also let it indent and format an entire document. | |
| 710 It has a special outline feature, which can greatly help you `getting | |
| 711 an overview' of a document. | |
| 712 | |
| 713 Apart from these special features, AUC TeX provides an large range of | |
| 714 handy Emacs macros, which in several different ways can help you write | |
| 715 your LaTeX documents fast and painless. | |
| 716 | |
| 717 ** redo.el-1.01, courtesy of Kyle Jones | |
| 718 | |
| 719 redo.el is a package that implements true redo mechanism in XEmacs | |
| 720 buffers. Once you load it from your `.emacs', you can bind the `redo' | |
| 721 command to a convenient key to use it. | |
| 722 | |
| 723 Emacs' normal undo system allows you to undo an arbitrary number of | |
| 724 buffer changes. These undos are recorded as ordinary buffer changes | |
| 725 themselves. So when you break the chain of undos by issuing some | |
| 726 other command, you can then undo all the undos. The chain of recorded | |
| 727 buffer modifications therefore grows without bound, truncated only at | |
| 728 garbage collection time. | |
| 729 | |
| 730 The redo/undo system is different in two ways: | |
| 731 | |
| 732 *** The undo/redo command chain is only broken by a buffer modification. | |
| 733 | |
| 734 You can move around the buffer or switch buffers and still come back | |
| 735 and do more undos or redos. | |
| 736 | |
| 737 *** The `redo' command rescinds the most recent undo without | |
| 738 recording the change as a _new_ buffer change. | |
| 739 | |
| 740 It completely reverses the effect of the undo, which includes making | |
| 741 the chain of buffer modification records shorter by one, to counteract | |
| 742 the effect of the undo command making the record list longer by one. | |
| 743 | |
| 744 ** edmacro.el-3.10, courtesy of Dave Gillespie, ported to XEmacs by | |
| 745 Hrvoje Niksic. | |
| 746 | |
| 747 Edmacro is a utility that provides easy editing of keyboard macros. | |
| 748 Originally written by Dave Gillespie, it has been mostly rewritten by | |
| 749 Hrvoje Niksic, in order to make it distinguish characters and integer, | |
| 750 as well as to adapt it to XEmacs keysyms. | |
| 751 | |
| 752 Press `C-x C-k' to invoke the `edit-kbd-macro' command that lets you | |
| 753 edit old as well as define new keyboard macros. You can also edit the | |
| 754 last 100 keystrokes and insert them into a macro to be bound to a key | |
| 755 or named as a command. The recorded/edited macros can be dumped to | |
| 756 `.emacs' file. | |
| 757 | |
| 758 ** xmine.el-1.8, courtesy of Jens Lautenbacher | |
| 759 | |
| 760 XEmacs now includes a minesweeper game with a full-featured graphics | |
| 761 and mouse interface. Invoke with `M-x xmine'. | |
| 762 | |
| 763 ** efs-1.15-x5 courtesy of Andy Norman and Michael Sperber | |
| 764 | |
| 765 EFS is now integrated with XEmacs, and replaces the old ange-ftp. It | |
| 766 has many more features, including info documentation, support for many | |
| 767 different FTP servers, and integration with dired. | |

| 797 * Lisp and internal changes in XEmacs 20.2 | |
| 798 ========================================== | |
| 799 | |
| 800 ** `defcustom' and `defgroup' can now be used to specify types and | |
| 801 placement of the user-settable variables. | |
| 802 | |
| 803 You can now specify the types of user-settable variables in your Lisp | |
| 804 packages to be customized by users. To do so, use `defcustom' as a | |
| 805 replacement for `defvar'. | |
| 806 | |
| 807 For example, the old declaration: | |
| 808 | |
| 809 (defvar foo-blurgoze nil | |
| 810 "*non-nil means that foo will act very blurgozely.") | |
| 811 | |
| 812 can be rewritten as: | |
| 813 | |
| 814 (defcustom foo-blurgoze nil | |
| 815 "*non-nil means that foo will act very blurgozely." | |
| 816 :type 'boolean | |
| 817 :group 'foo) | |
| 818 | |
| 819 From a package writer's point of view, nothing has been changed | |
| 820 However, the user can now type `M-x customize RET foo-blurgoze RET' to | |
| 821 customize the variable. | |
| 822 | |
| 823 Other, more complex data structures can be described with `defcustom' | |
| 824 too, for instance: | |
| 825 | |
| 826 (defcustom foo-hairy-alist '((somekey . "somestring") | |
| 827 (otherkey . (foo-doit)) | |
| 828 (thirdkey . [1 2 3])) | |
| 829 "*Alist describing the hairy options of the foo package. | |
| 830 The CAR of each element is a symbol, whereas the CDR can be either a | |
| 831 string, a form to evaluate, or a vector of integers. | |
| 832 New Emacs users simply adore alists like this one." | |
| 833 :type '(repeat (cons (symbol :tag "Key") | |
| 834 (choice string | |
| 835 (vector (repeat :inline t integer)) | |
| 836 sexp))) | |
| 837 :group 'foo) | |
| 838 | |
| 839 The user will be able to add and remove the entries to the list in a | |
| 840 visually appealing way, as well as save the settings to his/her | |
| 841 `.emacs'. | |
| 842 | |
| 843 Note that `defcustom' will also be included in GNU Emacs 19.35, and | |
| 844 that both XEmacs and GNU Emacs will be using it in the future. | |
| 845 Although the user-interface of customize may change, the Lisp | |
| 846 interface will remain the same. This is why we recommend that you use | |
| 847 `defcustom' for user-settable variables in your new Lisp packages. | |
| 848 | |
| 849 ** The `read-kbd-macro' function is now available. | |
| 850 | |
| 851 The `read-kbd-macro' function (as well as the read-time evaluated | |
| 852 `kbd' macro) from the edmacro package is now available in XEmacs. For | |
| 853 example: | |
| 854 | |
| 855 (define-key foo-mode-map (kbd "C-c <up>") 'foo-up) | |
| 856 | |
| 857 is completely equivalent to | |
| 858 | |
| 859 (define-key foo-mode-map [(control ?c) up] 'foo-up) | |
| 860 | |
| 861 The `kbd' macro is preferred over `read-kbd-macro' function , as it | |
| 862 evaluates before compiling, thus having no loading overhead. | |
| 863 | |
| 864 Using `kbd' is not necessary for GNU Emacs compatibility (GNU Emacs | |
| 865 supports the XEmacs-style keysyms), but adds to clarity. For example, | |
| 866 (kbd "C-?") is usually easier to read than [(control ??)]. The full | |
| 867 description of the syntax of keybindings accepted by `read-kbd-macro' | |
| 868 is documented in the docstring of `edmacro-mode'. | |
| 869 | |
| 870 ** Overlay compatibility is implemented. | |
| 871 | |
| 872 The overlay support in XEmacs is now functional. Written by Joe | |
| 873 Nuspl, the overlay compatibility library overlay.el is implemented on | |
| 874 top of the native XEmacs extents, and can be used as a GNU | |
| 875 Emacs-compatible way of changing display properties. | |
| 876 | |
| 877 ** You should use keysyms kp-* (kp-1, kp-2, ..., kp-enter etc.) | |
| 878 rather than the old form kp_*. The new form is also compatible with | |
| 879 GNU Emacs. | |
| 880 | |
| 881 ** The keysyms mouse-1, mouse-2, mouse-3 and down-mouse-1, | |
| 882 down-mouse-2, and down-mouse-3 have been added for GNU Emacs | |
| 883 compatibility. | |
| 884 | |
| 885 ** A new user variable `signal-error-on-buffer-boundary' has been | |
| 886 added. | |
| 887 | |
| 888 Set this to variable to nil to avoid XEmacs usual lossage of zmacs | |
| 889 region when moving up against a buffer boundary. | |
| 890 | |
| 891 ** lib-complete.el was MULE-ized. | |
| 892 | |
| 893 The commands `find-library', `find-library-other-window' and | |
| 894 `find-library-other-frame' now take an optional coding system | |
| 895 argument. | |
| 896 | |
| 897 ** Experimental support for Lisp reader macros #-, #+. | |
| 898 | |
| 899 The Common Lisp reader macros for feature test are now supported. This | |
| 900 feature is present for evaluation purposes and is subject to change. | |
| 901 | |
| 902 ** `values' now has a setf method | |
| 903 | |
| 904 ** The `eval-after-load' and `eval-next-after-load' functions are | |
| 905 now available. | |
| 906 | |
| 907 ** A bug that prevented `current-display-table' to be correctly set | |
| 908 with `set-specifier' has been fixed. | |
| 909 | |
| 910 ** The bug in easymenu which prevented multiple menus from being | |
| 911 accessible through button3 has been fixed. | |
| 912 | |
| 913 You can now safely use easymenu to define multiple menu entries in a | |
| 914 compatible way, with the added menus accessible via button3 as local | |
| 915 submenus. | |
| 916 | |
| 917 ** Many bugs in the scrollbar code have been fixed. | |
| 918 | |
| 919 ** First alpha level support of MS Windows NT is available, courtesy | |
| 920 of David Hobley and Marc Paquette. | |
| 921 | |
| 922 ** Wnn/egg now has initial support Courtesy of Jareth Hein. | |
| 923 | |
| 924 ** Some old non-working code has been removed until someone chooses | |
| 925 to work on it. | |
| 926 | |
| 927 This includes much of the NeXTStep stuff. The VMS support is also | |
| 928 likely to be removed in the future. | |
| 929 | |
| 930 ** Many files have been purged out of the etc/ directory. | |
| 931 | |
| 932 If you still need the purged files, look for them in the GNU Emacs | |
| 933 distribution. | |
| 934 | |
| 935 | |
| 936 * Major Differences Between 19.14 and 20.0 | |
| 937 =========================================== | |
| 938 | |
| 939 XEmacs 20.0 is the first public release to have support for MULE | |
| 940 (Multi-Lingual Emacs). The --with-mule configuration flag must be | |
| 941 used to enable Mule support. | |
| 942 | |
| 943 Many bugs have been fixed. An effort has been made to eradicate all | |
| 944 XEmacs crashes, although we are not quite done yet. The overall | |
| 945 quality of XEmacs should be higher than any previous release. XEmacs | |
| 946 now compiles with nary a warning with some compilers. | |
| 947 | |
| 948 -- Multiple character sets can be displayed in a buffer. The file | |
| 949 mule-doc/demo in the distribution contains a greeting in many | |
| 950 different languages. | |
| 951 | |
| 952 -- Although the Mule work is for all languages, particular effort has | |
| 953 been invested in Japanese, with particular focus on Japanese users | |
| 954 of Sun WorkShop. Many menubar labels have been translated into | |
| 955 Japanese. Martin Buchholz, the maintainer of MULE features within | |
| 956 XEmacs normally runs XEmacs in a Japanese language environment. | |
| 957 Some of the other contributors are Japanese, most importantly | |
| 958 Morioka Tomohiko, author of the TM package, providing MIME support | |
| 959 for Mail and News. | |
| 960 | |
| 961 -- Input for complex Asian languages is supported via XIM, a mechanism | |
| 962 introduced in X11R5 to allow applications to get localized input | |
| 963 without knowledge of the language. The way XIM works is that when | |
| 964 the locale has a complex character set, such as Japanese, and extra | |
| 965 minibuffer-like status window appears attached to various | |
| 966 application windows, and indicates the status of the input method. | |
| 967 Composed input in XEmacs should work the same as with other | |
| 968 applications. If Motif and Mule support is configured into XEmacs, | |
| 969 then XIM support is automatically configured in as well. | |
| 970 | |
| 971 -- TM (Tools for Mime) now comes with XEmacs. This provides MIME | |
| 972 (Multipurpose Internet Mail Extensions) support for Mail and News. | |
| 973 The primary author is Morioka Tomohiko. | |
| 974 | |
| 975 -- Japanese input can also be input using the `canna' input method. | |
| 976 This support was contributed by Morioka Tomohiko. Setting up canna | |
| 977 usually requires more user effort (and better knowledge of Japanese!) | |
| 978 than XIM, but provides a better-integrated input method. | |
| 979 | |
| 980 -- A mini-tutorial on using Mule: | |
| 981 | |
| 982 -- Every time data passes between XEmacs and the rest of the | |
| 983 environment, via file or process input or output, XEmacs must | |
| 984 convert between its internal multi-character representation and | |
| 985 the external representation (`coding system'). Many | |
| 986 difficulties with Mule are related to controlling these coding | |
| 987 system conversions. | |
| 988 | |
| 989 -- file-coding-system, file-coding-system-for-read, | |
| 990 overriding-file-coding-system, and file-coding-system-alist | |
| 991 are used to determine the coding systems used on file input | |
| 992 and output. | |
| 993 | |
| 994 -- For each process, (set-process-input-coding-system) and | |
| 995 (set-process-output-coding-system) determine the coding | |
| 996 system used for I/O from the process. | |
| 997 | |
| 998 -- Many other things are encoded using pathname-coding-system: | |
| 999 -- file and directory names | |
| 1000 -- window manager properties: window title, icon name | |
| 1001 -- process names and process arguments | |
| 1002 -- XIM input. | |
| 1003 | |
| 1004 -- In many cases, you will want to have the same values for all | |
| 1005 the above variables in many cases. For example, in a | |
| 1006 Japanese environment, you will want to use the 'euc-japan | |
| 1007 coding system consistently, except when running certain | |
| 1008 processes that do byte-oriented, rather than | |
| 1009 character-oriented I/O, such as gzip, or when processing Mail | |
| 1010 or News, where ISO2022-based coding systems are the norm, | |
| 1011 since they support multiple character sets. | |
| 1012 | |
| 1013 -- To add support for a new language or character set, start by | |
| 1014 trying to copy code in japanese-hooks.el. | |
| 1015 | |
| 1016 -- The traditional pre-Mule data conversion is equivalent to the | |
| 1017 'binary coding system under Mule. In this case all characters | |
| 1018 are treated as iso8859-1 (i.e. characters for English + Western | |
| 1019 European languages). | |
| 1020 | |
| 1021 -- many fileio-related commands such as find-file and write-file | |
| 1022 take an extra argument, coding-system, which specifies the | |
| 1023 encoding to be used with the file on disk. For example, here is | |
| 1024 a command that converts from the Japanese EUC to ISO2022 format: | |
| 1025 | |
| 1026 xemacs -batch -eval '(progn (find-file | |
| 1027 "locale-start.el.euc" (quote euc-japan)) (write-file | |
| 1028 "locale-start.el" nil (quote iso-2022-8-unix)))' | |
| 1029 | |
| 1030 Interactively, you can be prompted for a coding system by | |
| 1031 providing a prefix argument to the fileio command. In | |
| 1032 particular, C-u C-x C-f is a useful sequence to edit a file | |
| 1033 using a particular coding system. | |
| 1034 | |
| 1035 -- In an Asian locale (i.e. if $LANG is set to ja, ko, or zh), | |
| 1036 XEmacs automatically sets up a language environment assuming | |
| 1037 that the operating system encodes information in the national | |
| 1038 version of EUC, which supports English and the national | |
| 1039 language, but typically no other character sets. | |
| 1040 | |
| 1041 -- Command line processing should work much better now - no more order | |
| 1042 dependencies. | |
| 1043 | |
| 1044 -- Many many package upgraded (thanks go to countless maintainers): | |
| 1045 | |
| 1046 -- ediff 2.64 (Michael Kifer) | |
| 1047 -- Gnus 5.2.40 (Lars Magne Ingebrigtsen) | |
| 1048 -- w3 3.0.51 (Bill Perry) | |
| 1049 -- ilisp 5.8 (Chris McConnell, Ivan Vasquez, Marco Antoniotti, Rick | |
| 1050 Campbell) | |
| 1051 -- VM 5.97 (Kyle Jones) | |
| 1052 -- etags 11.78 (Francesco Potorti`) | |
| 1053 -- ksh-mode.el 2.9 | |
| 1054 -- vhdl-mode.el 2.73 (Rod Whitby) | |
| 1055 -- id-select.el (Bob Weiner) | |
| 1056 -- EDT/TPU emulation modes should work now for the first time. | |
| 1057 -- viper 2.92 (Michael Kifer) is now the `official' vi emulator for XEmacs. | |
| 1058 -- big-menubar should work much better now. | |
| 1059 -- mode-motion+.el 3.16 | |
| 1060 -- backup-dir 2.0 (Greg Klanderman) | |
| 1061 -- ps-print.el-3.05 (Jacques Duthen Prestataire) | |
| 1062 -- lazy-lock-1.15 (Simon Marshall) | |
| 1063 -- reporter 3.3 (Barry Warsaw) | |
| 1064 -- hm--html-menus 5.0 (Heiko Muenkel) | |
| 1065 -- cc-mode 4.322 (Barry Warsaw) | |
| 1066 -- elp 2.37 (Barry Warsaw) | |
| 1067 | |
| 1068 | |
| 1069 -- Many new packages have been added: | |
| 1070 -- m4-mode 1.8 (Andrew Csillag) | |
| 1071 -- crisp.el - crisp/brief emulation (Gary D. Foster) | |
| 1072 -- Johan Vroman's iso-acc.el has been ported to XEmacs by Alexandre Oliva | |
| 1073 -- psgml-1.01 (Lennart Staflin, James Clark) | |
| 1074 -- python-mode.el 2.83 (Barry Warsaw) | |
| 1075 -- vrml-mode.el (Ben Wing) | |
| 1076 -- enriched.el, face-menu.el (Boris Goldowsky, Michael Sperber) | |
| 1077 -- sh-script.el (Daniel Pfeiffer) | |
| 1078 -- decipher.el (Christopher J. Madsen) | |
| 1079 | |
| 1080 -- New function x-keysym-on-keyboard-p helps determine keyboard | |
| 1081 characteristics for key rebinding: | |
| 1082 | |
| 1083 x-keysym-on-keyboard-p: (KEYSYM &optional DEVICE) | |
| 1084 -- a built-in function. | |
| 1085 Return true if KEYSYM names a key on the keyboard of DEVICE. | |
| 1086 More precisely, return true if pressing a physical key | |
| 1087 on the keyboard of DEVICE without any modifier keys generates KEYSYM. | |
| 1088 Valid keysyms are listed in the files /usr/include/X11/keysymdef.h and in | |
| 1089 /usr/lib/X11/XKeysymDB, or whatever the equivalents are on your system. | |
| 1090 | |
| 1091 -- Installed info files are now compressed (support courtesy of Joseph J Nuspl) | |
| 1092 | |
| 1093 -- (load-average) works on Solaris, even if you're not root. Thanks to | |
| 1094 Hrvoje Niksic. | |
| 1095 | |
| 1096 -- OffiX drag-and-drop support added | |
| 1097 | |
| 1098 -- lots of syncing with 19.34 elisp files, most by Steven Baur | |
| 1099 | |
