1Emacs TODO List -*-outline-*- 2 3Copyright (C) 2001, 2002, 2003, 2004, 2005, 2006, 2007 4 Free Software Foundation, Inc. 5See the end of the file for license conditions. 6 7 8If you are ready to start working on any of these TODO items, we 9appreciate your help; please write to emacs-devel@gnu.org so we can be 10aware that the problem is being addressed, and talk with you how to do 11it best. Since Emacs is an FSF-copyrighted package, please be 12prepared to sign legal papers to transfer the copyright on your work 13to the FSF. 14 15* Small but important fixes needed in existing features: 16 17** Fix compilation when Xaw3d libraries are present but libxaw is not. 18In new X11 versions, xaw3dg-dev does not depend on libxaw-dev, so the 19latter need not be installed. As a result, all the source files that 20look for include files in X11/Xaw should look in X11/Xaw3d if we are 21using Xaw3d. 22 23** Compute the list of active keymaps *after* reading the first event. 24 25** Avoid using "iff" in doc strings. 26 27** mouse-autoselect-window should wait to select the window until 28the mouse is put to rest or after a delay or both, so that moving over 29a window doesn't select it. 30 31** In C-x d, the default if you type RET should be the directory name, 32but if you type M-n you should get the visited file name of the 33current buffer. 34 35** describe-face should show an example of text in the face. 36 37** Distribute a bar cursor of width > 1 evenly between the two glyphs 38 on each side of the bar (what to do at the edges?). 39 40** Make vc-checkin avoid reverting the buffer if has not changed after 41 the checkin. Comparing (md5 BUFFER) to (md5 FILE) should be enough. 42 43** buffer-offer-save should be a permanent local. 44 45** revert-buffer should eliminate overlays and the mark. 46 47** erase-buffer should perhaps disregard read-only properties of text. 48 49** Make occur correctly handle matches that span more than one line, 50 as well as overlapping matches. 51 52** Fix the kill/yank treatment of invisible text. At the moment, 53 invisible text is placed in the kill-ring, so that the contents of 54 the ring may not correspond to the text as displayed to the user. 55 It ought to be possible to omit text which is invisible (due to a 56 text-property, overlay, or selective display) from the kill-ring. 57 58** Change the way define-minor-mode handles autoloading. 59 It should not generate :require. Or :require in defcustom 60 should not be recorded in the user's custom-set-variables call. 61 62** Feature to change cursor shape when Emacs is idle (for more than 63 a specified time). 64 65** The buttons at the top of a custom buffer should not omit 66 variables whose values are currently hidden. 67 68** Clean up the variables in browse-url. Perhaps use a shell command string to 69 specify the browser instead of the mushrooming set of functions. 70 See also ESR's proposal for a BROWSER environment variable 71 <URL:http://www.catb.org/~esr/BROWSER/browse-url.patch>. 72 73** Enhance scroll-bar to handle tall line (similar to line-move). 74 75** Make occur handle multi-line matches cleanly with context. 76 77** In Custom buffers, put the option that turns a mode on or off first, 78 using a heuristic of some kind? 79 80** Define recompute-arg and recompute-arg-if for fix_command to use. 81 See rms message of 11 Dec 05. 82 83** Height returned by frame-parameter ... and height given to 84 make-frame does not mean the same thing. The former includes menu and 85 tool bar lines, the latter don't. frame-parameter should return height 86 without menu and tool bar lines. 87 88** In Emacs Info, examples of using Customize should be clickable 89 and they should create Custom buffers. 90 91** The toolbar should show keyboard equivalents in its tooltips. 92 93** Add function to redraw the tool bar. 94 95** M-! M-n should fetch the buffer-file-name as the default. 96 97** Redesign the load-history data structure so it can cope better 98 with evaluating definitions of the same function from different files, 99 recording which file the latest definition came from. 100 101** make back_comment use syntax-ppss or equivalent. 102 103** Improve configure's treatment of NON_GNU_CPP on Solaris. 104(patch available for after Emacs 22) 105 106** Consider improving src/sysdep.c's search for a fqdn. 107http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00782.html 108 109** Find a proper fix for rcirc multiline nick adding. 110http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00684.html 111 112* Important features: 113 114** Provide user-friendly ways to list all available font families, 115 list fonts, display a font as a sample, etc. [fx is looking at 116 multilingual font selection for the Unicode branch of Emacs.] 117 118** Provide a convenient way to select a color with the mouse. 119 120** Rewrite the face code to be simpler, clearer and faster. 121 122** Program Enriched mode to read and save in RTF. [Is there actually a 123 decent single definition of RTF? Maybe see info at 124 http://latex2rtf.sourceforge.net/.] This task seems to be addressed 125 by http://savannah.nongnu.org/projects/emacs-rtf/, which is still in 126 very early stages. 127 128** Implement something better than the current Refill mode. This 129 probably needs some primitive support. 130 131** Add a command to make a "Local Variables" section in the current buffer 132 and/or add a variable to the list. 133 134** Implement primitive and higher-level functions to allow filling 135 properly with variable-pitch faces. 136 137** Implement a smoother vertical scroll facility, one that allows 138 C-v to scroll through a tall image. The primitive operations 139 posn-at-point and posn-at-x-y should now make it doable in elisp. 140 141** Implement intelligent search/replace, going beyond query-replace 142 (see http://graphics.csail.mit.edu/~rcm/chi04.pdf). 143 144** Implement other text formatting properties. 145*** Footnotes that can appear either in place or at the end of the page. 146*** text property that says "don't break line in middle of this". 147 Don't break the line between two characters that have the 148 same value of this property. 149*** Discretionary hyphens that are not visible when they are at end of line. 150 151** Internationalize Emacs's messages. 152 153** Set up a facility to save backtraces when errors happen during 154specified filters, specified timers, and specified hooks. 155 156** Install mmc@maruska.dyndns.org's no-flicker change. 157 158** Add a "current vertical pixel level" value that goes with point, 159 so that motion commands can also move through tall images. 160 This value would be to point as window-vscroll is to window-start. 161 162** Address internationalization of symbols names essentially 163 as documentation, e.g. in command names and Custom. 164 165** Make the Lucid menu widget display multilingual text. [This 166 probably needs to be done from actual Emacs buffers, either directly 167 in the menu or by rendering in an unmapped window and copying the 168 pixels. The current code assumes a specific locale; that isn't good 169 enough even if X can render the arbitrary text] [The gtk 170 port now displays multilingual text in menus, but only insofar as 171 Emacs can encode it as utf-8 and gtk can display the result.] 172 Maybe making Lucid menus work like Gtk's (i.e. just force utf-8) is good 173 enough now that Emacs can encode most chars into utf-8. 174 175** Remove the limitation that window and frame widths and heights can 176 be only full columns/lines. 177 178* Other features we would like: 179 180** Remove the default toggling behavior of minor modes when called from elisp 181rather than interactively. This a trivial one-liner in easy-mode.el. 182** Create a category of errors called `user-error' for errors which are 183typically due to pilot errors and should thus be in debug-ignored-errors. 184 185** Give Tar mode all the features of Archive mode. 186 187** Create a category of errors called `process-error' 188 for some or all errors associated with using subprocesses. 189 190** Maybe reinterpret `parse-error' as a category of errors 191 and put some other errors under it. 192 193** A function to tell you the argument pattern of functions. 194 See `function-arity' in http://www.loveshack.ukfsn.org/emacs/fx-misc.el. 195 196** Make byte-compile warn when a doc string is too wide. 197 198** Make byte-optimization warnings issue accurate line numbers. 199 200** A function to check for customizable options that have been 201 set but not saved, and ask the user whether to save them. 202 This could go in kill-emacs-query-functions, to remind people 203 to save their changes. If the user says yes, show them 204 in a Custom buffer using customize-customized. 205 206** Record the sxhash of the default value for customized variables 207 and notify the user (maybe by adding a menu item or toolbar button, 208 as the detection can occur during autoload time) when the default 209 changes (meaning that new versions of the Lisp source with a changed 210 default value got installed) and offer ediff on the respective 211 customization buffers. 212 213** Emacs Lisp mode could put an overlay on the defun for every 214 function that has advice. The overlay could have `after-text' like 215 " [Function has advice]". It might look like (defun foo [Function 216 has advice] (x y) The overlay could also be a button that you could 217 use to view the advice. 218 219** Add a function to get the insertion-type of the markers in an overlay. 220 221** ange-ftp 222*** understand sftp 223 This is hard to make work because sftp doesn't print status 224 messages. 225 226*** Use MLS for ange-ftp-insert-directory if a list of files is specified. 227 228** Ability to map a key, including all modified-combinations. 229 E.g map mouse-4 to wheel-up as well as M-mouse-4 -> M-wheel-up 230 M-C-mouse-4 -> M-C-wheel-up, H-S-C-M-s-double-mouse-4 -> 231 H-S-C-M-s-double-wheel-up, ... 232 233** Beefed-up syntax-tables. 234*** recognize multi-character syntactic entities like `begin' and `end'. 235*** nested string-delimiters (for Postscript's (foo(bar)baz) strings). 236*** support for infix operators (with precedence). 237*** support for the $ (paired delimiter) in parse-partial-sexp. 238*** support for hook-chars whose effect on the parsing-state is specified 239 by elisp code. Thus a char could both close a string and open a comment 240 at the same time and do it in a context-sensitive way. 241*** ability to add mode-specific data to the partial-parse-state. 242 243** Add a way to convert a keyboard macro to equivalent Lisp code. 244 245** Have a command suggestion help system that recognizes patterns 246 of commands which could be replaced with a simpler common command. 247 It should not make more than one suggestion per 10 minutes. 248 249** Add a way to define input methods by computing them (when first used) 250 from other input methods. Then redefine C-x 8 to use a 251 user-selected input method, with the default being the union of 252 latin-1-prefix and latin-1-postfix. 253 254** Switch the Windows port to using Unicode keyboard input (maybe). 255 Based on http://msdn2.microsoft.com/en-us/library/ms633586.aspx, 256 this boils down to (1) calling RegisterClassW function to register 257 Emacs windows, and (2) modifying ALL system messages to use Unicode. 258 In particular, WM_CHAR messages, which result from keyboard input, 259 will then come in encoded in UTF-16. 260 261 One advantage of switching to Unicode is to toss encoded-kbd usage, 262 which will solve the problem with binding non-ASCII keys with 263 modifiers. 264 265 Problem: using this on Windows 9x/ME requires installing the 266 Microsoft Layer for Unicode (MSLU), which might not implement all 267 the required functionality that is available built-in on Windows XP 268 and later. We should not make this change if it would pressure 269 users of unauthorized copies of older versions of Windows to 270 downgrade to versions that require activation. 271 272** Implement a clean way to use different major modes for 273 different parts of a buffer. This could be useful in editing 274 Bison input files, for instance, or other kinds of text 275 where one language is embedded in another language. See 276 http://www.loveshack.ukfsn.org/emacs/multi-mode.el and also 277 mmm-mode, as reference for approaches took by others. 278 279** Arrange a way for an input method to return the first character 280 immediately, then replace it later. So that C-s a with 281 input method latin-1-postfix would immediately search for an a. 282 283** Give start-process the ability to direct standard-error 284 output to a different filter. 285 286** Make desktop.el save the "frame configuration" of Emacs (in some 287 useful sense). 288 289** Give desktop.el a feature to switch between different named 290 desktops. 291 292** Replace finder.el with something that generates an Info file 293 which gives the same information through a menu structure. [Dave 294 Love started on this.] 295 296** Add a cpio mode, more or less like tar mode. 297 298** Implement a variant of uncompress.el or jka-compr.el that works with 299 GNU Privacy Guard for encryption. [Code exists but isn't assigned. 300 See the Gnus development sources for assigned code concerning GPG 301 use with mail, which is probably a good start.] See also 302 http://www.loveshack.ukfsn.org/emacs/auto-crypt.tgz. 303 304** Save undo information in special temporary files, and reload it 305 when needed for undoing. This could extend undo capacity. 306 307** Change the Windows NT menu code 308 so that it handles the deep_p argument and avoids 309 regenerating the whole menu bar menu tree except 310 when the user tries to use the menubar. 311 312 This requires the RIT to forward the WM_INITMENU message to 313 the main thread, and not return from that message until the main 314 thread has processed the MENU_BAR_ACTIVATE_EVENT and regenerated 315 the whole menu bar. In the mean time, it should process other messages. 316 317** Get some major packages installed: W3 (development version needs 318 significant work), PSGML. Check the assignments file for other 319 packages which might go in and have been missed. 320 321** Make keymaps a first-class Lisp object (this means a rewrite of 322 keymap.c). What should it do apart from being opaque ? 323 multiple inheritance ? faster where-is ? no more fix_submap_inheritance ? 324 what else ? 325 326** Provide real menus on ttys. The MS-DOS implementation can serve as 327 an example how to do part of this; see the XMenu* functions on msdos.c. 328 329** Implement popular parts of the rest of the CL functions as compiler 330 macros in cl-macs. 331 332** Make compiler warnings about functions that might be undefined at run time 333 smarter, so that they know which files are required by the file being 334 compiled and don't warn about functions defined in them. 335 336** Highlight rectangles (`mouse-track-rectangle-p' in XEmacs). Already in CUA, 337 but it's a valuable feature worth making more general. 338 339** Support simultaneous tty and X frames. [See the multi-tty branch of Emacs 340 at http://lorentey.hu/project/emacs.] 341 342** Provide MIME support for Rmail using the Gnus MIME library. [Maybe 343 not now feasible, given Gnus maintenance decisions. fx looked at 344 this and can say where some of the problems are.] 345 346** Eliminate the storm of warnings concerning char/unsigned char 347 mismatches that we get with GCC 4.x and proprietary compilers on 348 various systems. They make it difficult to spot the important 349 warnings. 350 351** Fix anything necessary to use `long long' EMACS_INTs with GCC. 352 353** Split out parts of lisp.h and generate Makefile dependencies 354 automatically. 355 356** Update the FAQ. 357 358** Allow auto-compression-mode to use zlib calls if zlib is available. 359 [It's required for PNG, so may be linked anyhow.] 360 361** Add a --pristine startup flag which does -q --no-site-file plus 362 ignoring X resources (Doze equivalents?) and most of the 363 environment. What should not be ignored needs consideration. 364 365** Improve the GC (generational, incremental). (We may be able to use 366 the Boehm collector.) [See the Boehm-GC branch in CVS for work on 367 this.] 368 369** Check what hooks would help Emacspeak -- see the defadvising in W3. 370 371** Add definitions for symbol properties, for documentation purposes. 372 373** Add horizontal scroll bars. 374 375** Provide an optional feature which computes a scroll bar slider's 376 size and its position from lines instead of characters. 377 378** Add support for SVG (Scalable Vector Graphics) rendering to 379 Emacs. 380 381** Allow unknown image types to be rendered via an external program 382 converting them to, say, PBM (in the same way as PostScript?). 383 384** Display images with alpha channels, such as png, with the current 385background color of whatever frame it is displayed in. Currently, we 386use the default background color if specified in the png file, or, if 387that is unspecified, the background color of the frame in which the 388image was first created. Ideally, the image should display the 389background color of whichever frame it is being displayed in. The 390main complication is that this will require the loading of a new image 391object for each different background color. 392 393** Allow displaying an X window from an external program in a buffer, 394 e.g. to render graphics from Java applets. [gerd and/or wmperry 395 thought this was feasible.] 396 397** Allow images (not just text) in the margin to be mouse-sensitive. 398 (Requires recursing through display properties). Provide some way 399 to simulate mouse-clicks on marginal text without a mouse. 400 401** Implement Lisp functions to determine properly whether a character 402 is displayable (particularly needed in XFree 4, sigh). Use it to 403 define useful glyphs that may be displayed as images or unicodes 404 (with ASCIIfied fallback via latin1-disp). Examples include 405 box-drawing graphics in Custom buffers, W3 rules and tables, and 406 tree displays generally, mode-line mail indicator. [See work done 407 already for Emacs 22 and consult fx.] 408 409** Do something to make rms happy with fx's dynamic loading, and use it 410 to implement things like auto-loaded buffer parsers and database 411 access in cases which need more than Lisp. 412 413** Extend ps-print to deal with multiple font sizes, images, and extra 414 encodings. 415 416** Provide portable undumping using mmap (per gerd design). 417 418** Make byte-compile avoid binding an expanded defsubst's args 419when the body only calls primitives. 420 421** Use the XIE X extension, if available, for image display. 422 423** Make monochrome images display using the foreground and background 424 colors of the applicable faces. 425 426** Face remapping. 427 428** Make `format-time-string' preserve text properties like `format'. 429 430** Optionally make the cursor a little thinner at the end of a line 431 or the end of the buffer. 432 433** Add support for rendering antialiased text, probably using 434 XRender/Freetype. 435 436** Port the conservative stack marking code of Emacs' garbage collector 437 to more systems, so that we can completely get rid of GCPROs. Note 438 that Boehm garbage collector provides this. 439 440** Reorder defcustom's in each package so that the more important 441 options come first in the Customize buffers. This could be done by 442 either rearranging the file (since options are shown in the order 443 they appear in the *.el files), or by adding a few :set-after 444 attributes. 445 446** Maybe document the features of libraries missing from the manual (or 447 ancillary manuals, including the Lisp manual in some cases). 448 This is not worth doing for all of these packages and we need not 449 aim for completeness, but some may be worth documenting. 450 451 Here's a list which is probably not complete/correct: align, allout, 452 artist, ansi-color, array, battery, calculator, cdl, cmuscheme, 453 completion, cua, delim-col, dirtrack, double, echistory, elide-head, 454 easymenu, expand, flow-ctrl, format [format-alist], 455 generic/generic-x [various modes], kermit, log-edit, ledit 456 [obsolete?], makesum, midnight [other than in Kill Buffer node], 457 mouse-copy [?], mouse-drag, mouse-sel, net-utils, rcompile, 458 snmp-mode [?], soundex [should be interactive?], strokes [start from 459 the web page], talk, thingatpt [interactive functions?], type-break, 460 vcursor, xscheme, zone-mode [?], mlconvert [?], iso-cvt, iso-swed, 461 swedish, feedmail [?], uce, bruce, gametree, meese, page-ext, 462 refbib, refer, scribe, sgml-mode, spell, texinfo, underline, 463 cmacexp, hideif, mantemp [obsolete?], pcomplete, assoc, xml, 464 cvs-status (should be described in PCL-CVS manual); other progmodes, 465 probably in separate manual. 466 467** Convert the XPM bitmaps to PPM, replace the PBMs with them and scrap 468 the XPMs so that the colour versions work generally. (Requires care 469 with the colour used for the transparent regions.) 470 471** Convenient access to the `values' variable. It would be nice to have an 472 interface that would show you the printed reps of the elements of the 473 list in a menu, let you select one of the values, and put it into some 474 other variable, without changing the value of `values'. 475 476** (Controlled by a flag) make open and close syntax match exactly, 477 i.e. `(' doesn't match `]'. 478 479** Specify parameter ID-FORMAT in all calls to `file-attributes' and 480 `directory-files-and-attributes' where attributes UID or GID are used. 481 Whenever possible, use value 'string. 482 When done, change meaning of default value from 'integer to 'string. 483 If value 'integer is used nowhere, remove the parameter ID-FORMAT from 484 the definition of `file-attributes' and `directory-files-and-attributes' 485 and from the calls. 486 487** Modify the emulation of `stat' for MS-Windows to support large files. 488 The current version uses the stock Windows definition of `struct 489 stat', where the file's size is returned as a 32-bit integer. That 490 overflows for files larger than 4GB. To fix, modify `stat' to use 491 64-bit size, and use a declaration of `struct stat' that supports 492 such sizes. 493 494** Make language-info-alist customizable. Currently a user can customize 495 only the variable `current-language-environment'. 496 497** Improve language environment handling so that Emacs can fit 498 better to a users locale. Currently Emacs uses utf-8 language 499 environment for all utf-8 locales, thus a user in ja_JP.UTF-8 locale 500 are also put in utf-8 lang. env. In such a case, it is 501 better to use Japanese lang. env. but prefer utf-8 coding system. 502 503** Enhance locale handling: handle language, territory and charset 504 orthogonally and de-emphasize language environments. Use the locale 505 to set up more things, such as fontsets, the default Ispell 506 dictionary, diary format, calendar holidays and display, quoting 507 characters and phrase boundaries, sentence endings, collation for 508 sorting (at least for unicodes), HTTP Accept-language, patterns for 509 directory listings and compilation messages, yes-or-no replies, 510 common menu items when the toolkit supports it ... `locale-info' 511 needs extending for LC_COLLATE &c. [fx started on this.] 512 513** Eliminate the current restriction on header printing by ps-print. 514 Currently, a header can contain only single 1-byte charset in 515 addition to ASCII. 516 517** In ps-print, provide an user friendly interface to specify fonts. 518 519** OpenType font support for various complex scripts (e.g. Devanagari). 520 As X protocal doesn't provide a way to access OpenType Layout Tables 521 in a OpenType font of a server side, we need a way to utilize local 522 fonts (perhaps by directly using the Freetype library or indirectly 523 via Xft library). 524 525** Enhance word boundary detection for such a script that doesn't use 526 space at word boundary (e.g. Thai). 527 528** Implement interface programs with major Japanese conversion server 529 in lib-src so that they can be used from the input method 530 "japanese". Currently, most Japanese users are using external 531 packages (e.g. tamago, anthy) or an input method via XIM. 532 533** Let LEIM handle the Mode_switch key like XIM does (i.e. a toggle like C-\ 534but which can also be used as a modifier). 535 536** Improve Help buffers: Change the face of previously visited links (like 537 Info, but also with regard to namespace), add a forward button to make the 538 Help buffer more browser like and gives the value of lisp expressions 539 e.g auto-mode-alist, the right face. [nickrob@snap.net.nz has a patch 540 for this for inclusion after 22.1]. 541 542** Possibly make `list-holidays' eval items in the calendar-holidays variable. 543 See thread 544 <http://lists.gnu.org/archive/html/emacs-devel/2006-02/msg01034.html>. 545 [rgm@gnu.org will look at this after 22.1] 546 547** Possibly make cal-dst use the system timezone database directly. 548 See thread 549 <http://lists.gnu.org/archive/html/emacs-pretest-bug/2006-11/msg00060.html> 550 551* Internal changes 552 553** Cleanup all the GC_ mark bit stuff -- there is no longer any distinction 554 since the mark bit is no longer stored in the Lisp_Object itself. 555 556** Merge ibuffer.el and buff-menu.el. 557 More specifically do what's needed to make ibuffer.el the default, 558 or just an extension of buff-menu.el. 559 560** Use pcomplete by default in shell-mode. 561 This means to make it behave (by default) more like the current code. 562 Use it also for read-shell-command, M-x compile, ... 563 564** Merge sendmail.el and messages.el. 565 Probably not a complete merge, but at least arrange for messages.el to be 566 a derived mode of sendmail.el. Or arrange for messages.el to be split 567 into a small core and "the rest" so that we use less resources as long as 568 we stick to the features provided in sendmail.el. 569 570** Replace gmalloc.c with the modified Doug Lea code from the current 571 GNU libc so that the special mmapping of buffers can be removed -- 572 that apparently loses under Solaris, at least. [fx has mostly done 573 this.] 574 575** Rewrite make-docfile to be clean and maintainable. 576 577** Add an inferior-comint-minor-mode to capture the common set of operations 578 offered by major modes that offer an associated inferior 579 comint-derived mode. I.e. basically make cmuscheme.el/inf-lisp.el generic. 580 For use by sml-mode, python-mode, tex-mode, scheme-mode, lisp-mode, 581 haskell-mode, tuareg-mode, ... 582 583** Make SYNC_INPUT the default. 584 All loops using immediate_quit need to be checked to ensure that 585 C-g can interrupt them, in case of an infinite loop. Once we 586 switch to using SYNC_INPUT, we can remove the BLOCK_INPUTs in the 587 allocation functions (allocate_string etc.) without worrying about 588 data munging. 589 590** Add "link" button class 591 Add a standard button-class named "link", and make all other link-like 592 button classes inherit from it. Set the default face of the "link" button 593 class to the standard "link" face. 594 595* Other known bugs: 596 597** a two-char comment-starter whose two chars are symbol constituents will 598not be noticed if it appears within a word. 599 600** Fix unexelf.c to handle the .data.rel and .data.rel.local 601 sections made by GCC 3.4 on IRIX. 602 603 604This file is part of GNU Emacs. 605 606GNU Emacs is free software; you can redistribute it and/or modify 607it under the terms of the GNU General Public License as published by 608the Free Software Foundation; either version 2, or (at your option) 609any later version. 610 611GNU Emacs is distributed in the hope that it will be useful, 612but WITHOUT ANY WARRANTY; without even the implied warranty of 613MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
