114 | This version of WoMan should run with GNU Emacs 20.3 or later on any | |
115 | platform. It has not been tested, and may not run, with any other | |
116 | version of Emacs. It was developed primarily on various versions of | |
117 | Microsoft Windows, but has also been tested on MS-DOS, and various | |
256e6c04 | 118 | versions of UNIX and GNU/Linux. |
a9212536 EZ |
119 | |
120 | WoMan is distributed with GNU Emacs 21, and the current source code and | |
121 | documentation files are available from | |
122 | @uref{http://centaur.maths.qmw.ac.uk/Emacs/WoMan/, my web server}. | |
123 | ||
124 | WoMan implements a subset of the formatting performed by the Emacs | |
a42bec1c | 125 | @code{man} (or @code{manual-entry}) command to format a Unix-style |
a9212536 EZ |
126 | @dfn{manual page} (usually abbreviated to @dfn{man page}) for display, |
127 | but without calling any external programs. It is intended to emulate | |
128 | the whole of the @code{ROFF -man} macro package, plus those @code{ROFF} | |
129 | requests (@pxref{Background, , Background}) that are most commonly used | |
130 | in man pages. However, the emulation is modified to include the | |
131 | reformatting done by the Emacs @code{man} command. No hyphenation is | |
132 | performed. | |
133 | ||
134 | @table @b | |
135 | @item Advantages | |
136 | Much more direct, does not require any external programs. Supports | |
137 | completion on man page names. | |
138 | @item Disadvantages | |
139 | Not a complete emulation. Currently no support for @code{eqn} or | |
140 | @code{tbl}. Slightly slower for large man pages (but usually faster for | |
141 | small- and medium-size pages). | |
142 | @end table | |
143 | ||
144 | This browser works quite well on simple well-written man files. It | |
145 | works less well on idiosyncratic files that ``break the rules'' or use | |
146 | the more obscure @code{ROFF} requests directly. Current test results | |
147 | are available in the file | |
4711065a | 148 | @uref{http://centaur.maths.qmw.ac.uk/Emacs/WoMan/files/woman.status, |
a9212536 EZ |
149 | @file{woman.status}}. |
150 | ||
151 | WoMan supports the use of compressed man files via | |
152 | @code{auto-compression-mode} by turning it on if necessary. But you may | |
153 | need to adjust the user option @code{woman-file-compression-regexp}. | |
154 | @xref{Interface Options, , Interface Options}. | |
155 | ||
156 | Brief help on the WoMan interactive commands and user options, all of | |
157 | which begin with the prefix @code{woman-} (or occasionally | |
158 | @code{WoMan-}), is available most easily by loading WoMan and then | |
159 | either running the command @code{woman-mini-help} or selecting the WoMan | |
160 | menu option @samp{Mini Help}. | |
161 | ||
162 | WoMan is (of course) still under development! Please | |
a42bec1c | 163 | @email{F.J.Wright@@qmw.ac.uk, let me know} what doesn't work---I am |

174 | ||
a42bec1c | 175 | WoMan is a browser for traditional Unix-style manual page documentation. |
a9212536 EZ |
176 | Each such document is conventionally referred to as a @dfn{manual page}, |
177 | or @dfn{man page} for short, even though some are very much longer than | |
a42bec1c | 178 | one page. A man page is a document written using the Unix ``man'' |
a9212536 EZ |
179 | macros, which are themselves written in the NROFF/TROFF text processing |
180 | markup language. @code{NROFF} and @code{TROFF} are text processors | |
181 | originally written for the UNIX operating system by Joseph F. Ossanna at | |
182 | Bell Laboratories, Murray Hill, New Jersey, USA@. They are closely | |
183 | related, and except in the few cases where the distinction between them | |
184 | is important I will refer to them both ambiguously as @dfn{ROFF}. | |
185 | ||
186 | @code{ROFF} markup consists of @dfn{requests} and @dfn{escape | |
187 | sequences}. A request occupies a complete line and begins with either a | |
188 | period or a single forward quote. An escape sequences is embedded | |
189 | within the input text and begins (by default) with a backslash. The | |
190 | original man macro package defines 20 new @code{ROFF} requests | |
191 | implemented as macros, which were considered to be sufficient for | |
192 | writing man pages. But whilst in principle man pages use only the man | |
193 | macros, in practice a significant number use many other @code{ROFF} | |
194 | requests. | |
195 | ||
196 | The distinction between @code{TROFF} and @code{NROFF} is that | |
197 | @code{TROFF} was designed to drive a phototypesetter whereas | |
6b61353c | 198 | @code{NROFF} was designed to produce essentially @acronym{ASCII} output for a |
a9212536 EZ |
199 | character-based device similar to a teletypewriter (usually abbreviated |
200 | to ``teletype'' or ``tty''). Hence, @code{TROFF} supports much finer | |
201 | control over output positioning than does @code{NROFF} and can be seen | |
202 | as a forerunner of @TeX{}. Traditionally, man pages are either | |
203 | formatted by @code{TROFF} for typesetting or by @code{NROFF} for | |
204 | printing on a character printer or displaying on a screen. Of course, | |
205 | over the last 25 years or so, the distinction between typeset output on | |
206 | paper and characters on a screen has become blurred by the fact that | |
207 | most screens now support bit-mapped displays, so that any information | |
208 | that can be printed can also be rendered on screen, the only difference | |
209 | being the resolution. | |
210 | ||
a42bec1c | 211 | Nevertheless, Unix-style manual page documentation is still normally |
a9212536 EZ |
212 | browsed on screen by running a program called @code{man}. This program |
213 | looks in a predefined set of directories for the man page matching a | |
214 | specified topic, then either formats the source file by running | |
215 | @code{NROFF} or recovers a pre-formatted file, and displays it via a | |
216 | pager such as @code{more}. @code{NROFF} normally formats for a printer, | |
217 | so it paginates the output, numbers the pages, etc., most of which is | |
218 | irrelevant when the document is browsed as a continuous scrollable | |
219 | document on screen. The only concession to on-screen browsing normally | |
220 | implemented by the @code{man} program is to squeeze consecutive blank | |
221 | lines into a single blank line. | |
222 | ||
223 | For some time, Emacs has offered an improved interface for browsing man | |
224 | pages in the form of the Emacs @code{man} (or @code{manual-entry}) | |
225 | command, see @ref{Documentation, man, Documentation Commands, emacs, GNU | |
226 | Emacs Manual}. | |
227 | This command runs @code{man} as described above, perhaps in | |
228 | the background, and then post-processes the output to remove much of the | |
229 | @code{NROFF} pagination such as page headers and footers, and places the | |
230 | result into an Emacs buffer. It puts this buffer into a special major | |
231 | mode, which is tailored for man page browsing, and provides a number of | |
232 | useful navigation commands, support for following references, etc. It | |
233 | provides some support for special display faces (fonts), but no special | |
234 | menu or mouse support. The Emacs man package appears to have been | |
235 | developed over about 10 years, from the late 1980s to the late 1990s. | |
236 | ||
237 | There is considerable inefficiency in having @code{NROFF} paginate a | |
238 | document and then removing most of the pagination! | |
239 | ||
240 | WoMan is an Emacs Lisp library that provides an emulation of the | |
241 | functionality of the Emacs @code{man} command, the main difference being | |
242 | that WoMan does not use any external programs. The only situation in | |
243 | which WoMan might use an external program is when the source file is | |
244 | compressed, when WoMan will use the standard Emacs automatic | |
245 | decompression facility, which does call an external program. | |
246 | ||
247 | I began developing WoMan in the Spring of 1997 and the first version was | |
248 | released in May 1997. The original motivation for WoMan was the fact | |
a42bec1c EZ |
249 | that many GNU and Unix programs are ported to other platforms and come |
250 | with Unix-style manual page documentation. This may be difficult to | |
251 | read because ports of the Unix-style @code{man} program can be a little | |
a9212536 EZ |
252 | awkward to set up. I decided that it should not be too hard to emulate |
253 | the 20 @code{man} macros directly, without treating them as macros and | |
254 | largely ignoring the underlying @code{ROFF} requests, given the text | |
255 | processing capabilities of Emacs. This proved to be essentially true, | |
256 | and it did not take a great deal of work to be able to format simple man | |
257 | pages acceptably. | |
258 | ||
259 | One problem arose with the significant number of man pages that use | |
260 | @code{ROFF} requests in addition to the @code{man} macros, and since | |
261 | releasing the first version of WoMan I have been continually extending | |
262 | it to support more @code{ROFF} requests. WoMan can now format a | |
263 | significant proportion of the man pages that I have tested, either well | |
264 | or at least readably. However, I have added capabilities partly by | |
265 | making additional passes through the document, a design that is | |
266 | fundamentally flawed. This can only be solved by a major re-design of | |
267 | WoMan to handle the major formatting within a single recursive pass, | |
268 | rather than the present multiple passes without any significant | |
269 | recursion. There are some @code{ROFF} requests that cannot be handled | |
270 | satisfactorily within the present design. Some of these are currently | |
df9d7630 | 271 | handled by kludges that ``usually more or less work.'' |
a9212536 EZ |
272 | |
273 | The principle advantage of WoMan is that it does not require @code{man}, | |
df9d7630 | 274 | and indeed the name WoMan is a contraction of ``without man.'' But it |
a9212536 EZ |
275 | has other advantages. It does not paginate the document, so it does not |
276 | need to un-paginate it again, thereby saving time. It could take full | |
277 | advantage of the display capabilities available to it, and I hope to | |
278 | develop WoMan to take advantage of developments in Emacs itself. At | |
279 | present, WoMan uses several display faces to support bold and italic | |
280 | text, to indicate other fonts, etc. The default faces are also | |
28665d46 | 281 | colored, but the choice of faces is customizable. WoMan provides menu |
a9212536 EZ |
282 | support for navigation and mouse support for following references, in |
283 | addition to the navigation facilities provided by @code{man} mode. | |
284 | WoMan has (this) texinfo documentation! | |
285 | ||
286 | WoMan @emph{does not} replace @code{man}, although it does use a number | |
287 | of the facilities implemented in the Emacs @code{man} library. WoMan | |
288 | and man can happily co-exist, which is very useful for comparison and | |
289 | debugging purposes. The only way in which WoMan affects @code{man} is | |
290 | that it adds a timer to indicate how long @code{man} has taken to format | |
291 | a man page. The timing is as compatible as possible with the timing | |
292 | built into WoMan, for as fair a comparison as possible. The time | |
293 | comparison seems to depend on the details of the platform, the version | |
294 | of @code{man} in use, etc, but times are similar and WoMan is never | |
295 | significantly slower than @code{man}. This is despite the fact that | |
296 | WoMan is running byte code whereas most of the formatting done by | |
297 | @code{man} uses machine code, and is a testimony to the quality of the | |
298 | Emacs Lisp system. | |
299 | ||
6b61353c KH |
300 | @code{NROFF} simulates non-@acronym{ASCII} characters by using one or more |
301 | @acronym{ASCII} characters. WoMan should be able to do much better than | |
a9212536 EZ |
302 | this. I have recently begun to add support for WoMan to use more of the |
303 | characters in its default font and to use a symbol font, and it is an | |
304 | aspect that I intend to develop further in the near future. It should | |
305 | be possible to move WoMan from an emulation of @code{NROFF} to an | |
306 | emulation of @code{TROFF} as GNU Emacs moves to providing bit-mapped | |
307 | display facilities. | |

315 | @cindex setup | |
316 | ||
317 | No installation is necessary if you just want to run the version of | |
318 | WoMan distributed with GNU Emacs 21 or later, although some additional | |
319 | setup may still be desirable. | |
320 | ||
321 | If you are installing @file{woman.el}, either to update the version | |
322 | distributed with GNU Emacs or because WoMan was not distributed with | |
323 | your version of Emacs, then you need to put the file in a directory in | |
324 | your Emacs load path and byte compile it. A good directory to use is | |
325 | the @file{site-lisp} directory in your Emacs file tree, e.g.@: | |
326 | @file{/usr/local/share/emacs/@var{version}/site-lisp/} (where | |
327 | @var{version} is your Emacs version), provided you have write access to | |
328 | it. If you use a directory that is not included by default in your | |
329 | Emacs load path then you need to add something like this to your | |
28665d46 | 330 | @file{.emacs} initialization file: |
a9212536 EZ |
331 | |
332 | @lisp | |
333 | (add-to-list 'load-path "my-lisp") | |
334 | @end lisp | |
335 | ||
336 | @noindent | |
337 | where @file{my-lisp} is the pathname of the directory. @xref{Init File, , | |
338 | The Init File ~/.emacs, emacs, The Emacs Editor}, for further details on | |
339 | customizing Emacs in general. | |
340 | ||
341 | You can byte-compile the file by using the Emacs command | |
342 | @code{byte-compile-file} or by opening the directory containing the | |
343 | file, putting point on it and pressing the key @kbd{B}. (In fact, if | |
344 | the file is compiled then it is only the compiled file that needs to be | |
345 | in the Emacs load path, but leaving the source file there will do no | |
346 | harm.) | |
347 | ||
348 | @heading Setup | |
349 | ||
350 | Setup that is either necessary or desirable consists of adding a small | |
28665d46 | 351 | amount of Emacs Lisp code to your @file{.emacs} initialization file. It |
a9212536 EZ |
352 | may be necessary (or at least convenient) to make WoMan autoload (if you |
353 | are not running GNU Emacs 21 or later) and to set the search path used | |
354 | by the @code{woman} interface. You may also find it convenient to make | |
355 | various WoMan menu and key bindings available and to make WoMan | |
356 | customizable even before WoMan has been loaded. | |
357 | ||
358 | It is possible to run WoMan from a command line (from outside or even | |
359 | from inside Emacs) by suitably configuring your command interpreter. | |

396 | The next step is necessary if you want to use the friendliest WoMan | |
397 | interface, which is recommended in general. If the @code{MANPATH} | |
398 | environment variable is set then WoMan will use it; alternatively (or | |
399 | additionally), if your platform uses a man configuration file (as do | |
400 | many versions of Linux) then WoMan will use it, provided it can find it. | |

519 | WoMan provides three user interfaces for finding and formatting man pages: | |
520 | ||
521 | @itemize @bullet | |
522 | @item | |
523 | a topic interface similar to that provided by the standard Emacs | |
524 | @code{man} command; | |
525 | ||
526 | @item | |
527 | a family of filename interfaces analogous to the standard Emacs | |
528 | @code{view-file} command; | |
529 | ||
530 | @item | |
531 | an automatic interface that detects the file type from its contents. | |
532 | (This is currently neither well tested, well supported nor recommended!) | |
533 | @end itemize | |
534 | ||
535 | The topic and filename interfaces support completion in the usual way. | |
536 | ||
537 | The topic interface is generally the most convenient for regular use, | |
538 | although it may require some special setup, especially if your machine | |
539 | does not already have a conventional @code{man} installation (which | |
540 | WoMan tries to detect). | |
541 | ||
542 | The simplest filename interface command @code{woman-find-file} can | |
543 | always be used with no setup at all (provided WoMan is installed and | |
544 | loaded or set up to autoload). | |
545 | ||
546 | The automatic interface always requires special setup. | |

549 | @heading Case-Dependence of Filenames | |
550 | ||
551 | @cindex case-sensitivity | |
552 | @vindex w32-downcase-file-names | |
553 | By default, WoMan ignores case in file pathnames only when it seems | |
554 | appropriate. Microsoft Windows users who want complete case | |
555 | independence should set the special NTEmacs variable | |
556 | @code{w32-downcase-file-names} to @code{t} and use all lower case when | |
557 | setting WoMan file paths. | |

568 | @section Topic Interface | |
569 | @cindex topic interface | |
570 | ||
571 | The topic interface is accessed principally via the command | |
572 | @code{woman}. The same command can be accessed via the menu item | |
573 | @samp{Help->Manuals->Read Man Page (WoMan)...} either once WoMan has been | |
574 | loaded or if it is set up specially. @xref{Installation, , Installation | |
575 | and Setup}. The command reads a manual topic in the minibuffer, which | |
576 | can be the @dfn{basename} of a man file anywhere in the man file | |
577 | structure. The ``basename'' in this context means the filename without | |
578 | any directory component and without any extension or suffix components | |
579 | that relate to the file type. So, for example, if there is a compressed | |
580 | source file in Chapter 5 of the UNIX Programmer's Manual with the full | |
581 | pathname @file{/usr/local/man/man5/man.conf.5.gz} then the topic is | |
582 | @code{man.conf}. Provided WoMan is configured correctly, this topic | |
583 | will appear among the completions offered by @code{woman}. If more than | |
584 | one file has the same topic name then WoMan will prompt for which file | |
585 | to format. Completion of topics is case insensitive. | |
586 | ||
587 | Clearly, @code{woman} has to know where to look for man files and there | |
588 | are two customizable user options that store this information: | |
589 | @code{woman-manpath} and @code{woman-path}. @xref{Interface Options, , | |
590 | Interface Options}. If @code{woman-manpath} is not set explicitly then | |
591 | WoMan tries to pick up the information that would be used by the | |
592 | @code{man} command, as follows. If the environment variable | |
593 | @code{MANPATH} is set, which seems to be the standard mechanism under | |
594 | UNIX, then WoMan parses that. Otherwise, if WoMan can find a | |
595 | configuration file named (by default) @file{man.conf} (or something very | |
596 | similar), which seems to be the standard mechanism under GNU/Linux, then | |
597 | it parses that. To be precise, ``something very similar'' means having | |
598 | two name components separated by a dot and respectively containing | |
df9d7630 | 599 | @samp{man} and beginning with @samp{conf}, e.g.@: @file{manual.configuration}. |
a9212536 EZ |
600 | The search path and/or precise full path name for this file are set by |
601 | the value of the customizable user option @code{woman-man.conf-path}. | |
602 | If all else fails, WoMan uses a plausible default man search path. | |
603 | ||
604 | If the above default configuration does not work correctly for any | |
605 | reason then simply customize the value of @code{woman-manpath}. To | |
606 | access man files that are not in a conventional man file hierarchy, | |
607 | customize the value of @code{woman-path} to include the directories | |
608 | containing the files. In this way, @code{woman} can access manual files | |
609 | @emph{anywhere} in the entire file system. | |
610 | ||
611 | There are two differences between @code{woman-manpath} and | |
612 | @code{woman-path}. Firstly, the elements of @code{woman-manpath} must | |
613 | be directories that contain @emph{directories of} man files, whereas the | |
614 | elements of @code{woman-path} must be directories that contain man files | |
615 | @emph{directly}. Secondly, the last directory component of each element | |
616 | of @code{woman-path} is treated as a regular (Emacs) match expression | |
617 | rather than a fixed name, which allows collections of related | |
618 | directories to be specified succinctly. | |
619 | ||
620 | For topic completion to work, WoMan must build a list of all the manual | |
621 | files that it can access, which can be very slow, especially if a | |
622 | network is involved. For this reason, it caches various amounts of | |
623 | information, after which retrieving it from the cache is very fast. If | |
624 | the cache ever gets out of synchronism with reality, running the | |
625 | @code{woman} command with a prefix argument (e.g.@: @kbd{C-u M-x woman}) | |
626 | will force it to rebuild its cache. This is necessary only if the names | |
627 | or locations of any man files change; it is not necessary if only their | |
628 | contents change. It would always be necessary if such a change occurred | |
629 | whilst Emacs were running and after WoMan has been loaded. It may be | |
630 | necessary if such a change occurs between Emacs sessions and persistent | |
631 | caching is used, although WoMan can detect some changes that invalidate | |
632 | its cache and rebuild it automatically. | |
633 | ||
634 | Customize the variable @code{woman-cache-filename} to save the cache | |
635 | between Emacs sessions. This is recommended only if the @code{woman} | |
636 | command is too slow the first time it is run in an Emacs session, while | |
637 | it builds its cache in main memory, which @emph{may} be @emph{very} | |
638 | slow. @xref{Cache, , The WoMan Topic Cache}, for further details. | |

650 | @cindex cache, topic | |
651 | ||
652 | The amount of information that WoMan caches (in main memory and, | |
653 | optionally, saved to disc) is controlled by the user option | |
654 | @code{woman-cache-level}. There is a trade-off between the speed with | |
655 | which WoMan can find a file and the size of the cache, and the default | |
656 | setting gives a reasonable compromise. | |
657 | ||
658 | The @code{woman} command always performs a certain amount of caching in | |
659 | main memory, but it can also write its cache to the filestore as a | |
660 | persistent cache under control of the user option | |
661 | @code{woman-cache-filename}. If persistent caching is turned on then | |
662 | WoMan re-loads its internal cache from the cache file almost | |
663 | instantaneously, so that there is never any perceptible start-up delay | |
664 | @emph{except} when WoMan rebuilds its cache. Persistent caching is | |
665 | currently turned off by default. This is because users with persistent | |
666 | caching turned on may overlook the need to force WoMan to rebuild its | |
667 | cache the first time they run it after they have installed new man | |
668 | files; with persistent caching turned off, WoMan automatically rebuilds | |
669 | its cache every time it is run in a new Emacs session. | |
670 | ||
671 | A prefix argument always causes the @code{woman} command (only) to | |
672 | rebuild its topic cache, and to re-save it to | |
256e6c04 | 673 | @code{woman-cache-filename} if this variable has a non-@code{nil} value. This |
a9212536 EZ |
674 | is necessary if the @emph{names} of any of the directories or files in |
675 | the paths specified by @code{woman-manpath} or @code{woman-path} change. | |
676 | If WoMan user options that affect the cache are changed then WoMan will | |
677 | automatically update its cache file on disc (if one is in use) the next | |
678 | time it is run in a new Emacs session. | |

684 | @cindex word at point | |
685 | @cindex point, word at | |
686 | ||
687 | By default, the @code{woman} command uses the word nearest to point in | |
688 | the current buffer as a suggestion for the topic to look up. The topic | |
689 | must be confirmed or edited in the minibuffer. This suggestion can be | |
690 | turned off, or @code{woman} can use the suggested topic without | |
691 | confirmation if possible, which is controlled by customizing the user | |
692 | option @code{woman-topic-at-point} to @code{nil} or @code{t} | |
693 | respectively. (Its default value is neither @code{nil} nor @code{t}, | |
694 | meaning ask for confirmation.) | |
695 | ||
696 | The variable @code{woman-topic-at-point} can also be rebound locally | |
697 | (using @code{let}), which may be useful to provide special private key | |
698 | bindings, e.g.@: this key binding for @kbd{C-c w} runs WoMan on the topic | |

721 | all (provided WoMan is installed and loaded or set up to autoload). | |
722 | This command can be used to browse any accessible man file, regardless | |
723 | of its filename or location. If the file is compressed then automatic | |
724 | file decompression must already be turned on (e.g.@: see the | |
a42bec1c | 725 | @samp{Help->Options} submenu)---it is turned on automatically only by |

726 | the @code{woman} topic interface. |
727 | ||
728 | @findex woman-dired-find-file | |
729 | Once WoMan is loaded (or if specially set up), various additional | |
730 | commands in this family are available. In a dired buffer, the command | |
731 | @code{woman-dired-find-file} allows the file on the same line as point | |
732 | to be formatted and browsed by WoMan. It is bound to the key @kbd{W} in | |
733 | the dired mode map and added to the dired major mode menu. It may also | |
734 | be bound to @kbd{w}, unless this key is bound by another library, which | |
735 | it is by @code{dired-x}, for example. Because it is quite likely that | |
736 | other libraries will extend the capabilities of such a commonly used | |
737 | mode as dired, the precise key bindings added by WoMan to the dired mode | |
738 | map are controlled by the user option @code{woman-dired-keys}. | |
739 | ||
740 | @findex woman-tar-extract-file | |
741 | When a tar (Tape ARchive) file is visited in Emacs, it is opened in tar | |
742 | mode, which parses the tar file and shows a dired-like view of its | |
743 | contents. The WoMan command @code{woman-tar-extract-file} allows the | |
744 | file on the same line as point to be formatted and browsed by WoMan. It | |
745 | is bound to the key @kbd{w} in the tar mode map and added to the tar | |
746 | major mode menu. | |
747 | ||
748 | The command @code{woman-reformat-last-file}, which is bound to the key | |
749 | @kbd{R} in WoMan mode and available on the major mode menu, reformats | |
750 | the last file formatted by WoMan. This may occasionally be useful if | |
751 | formatting parameters, such as the fill column, are changed, or perhaps | |
752 | if the buffer is somehow corrupted. | |
753 | ||
754 | @findex woman-decode-buffer | |
755 | The command @code{woman-decode-buffer} can be used to decode and browse | |
756 | the current buffer if it is visiting a man file, although it is | |
757 | primarily used internally by WoMan. | |

763 | @cindex automatic interface | |
764 | ||
765 | Emacs provides an interface to detect automatically the format of a file | |
766 | and decode it when it is visited. It is used primarily by the | |
767 | facilities for editing rich (i.e.@: formatted) text, as a way to store | |
6b61353c | 768 | formatting information transparently as @acronym{ASCII} markup. WoMan can in |
a9212536 EZ |
769 | principle use this interface, but it must be configured explicitly. |
770 | ||
771 | This use of WoMan does not seem to be particularly advantageous, so it | |
772 | is not really supported. It originated during early experiments on how | |
773 | best to implement WoMan, before I implemented the current topic | |
774 | interface, and I subsequently stopped using it. I might revive it as a | |
775 | mechanism for storing pre-formatted WoMan files, somewhat analogous to | |
a42bec1c | 776 | the standard Unix @code{catman} facility. In the meantime, it exists |
a9212536 EZ |
777 | for anyone who wants to experiment with it. Once it is set up it is |
778 | simply a question of visiting the file and there is no WoMan-specific | |
779 | user interface! | |
780 | ||
781 | To use it, put something like this in your @file{.emacs} file. [The | |

805 | Once a man page has been found and formatted, WoMan provides a browsing | |

807 | Emacs @code{man} command (and much of the code is inherited from the | |
808 | @code{man} library, which WoMan currently requires). Many WoMan | |
809 | facilities can be accessed from the WoMan major mode menu as well as via | |
810 | key bindings, etc. | |
811 | ||
812 | WoMan does not produce any page breaks or page numbers, and in fact does | |
813 | not paginate the man page at all, since this is not appropriate for | |
814 | continuous online browsing. It produces a document header line that is | |
815 | constructed from the standard man page header and footer. Apart from | |
816 | that, the appearance of the formatted man page should be almost | |
817 | identical to what would be produced by @code{man}, with consecutive | |

835 | Fonts used by @code{ROFF} are handled by WoMan as faces, the details of | |
836 | which are customizable. @xref{Faces, , Faces}. WoMan supports both the | |
837 | italic and bold fonts normally used in man pages, together with a single | |
838 | face to represent all unknown fonts (which are occasionally used in | |
839 | ``non-standard'' man pages, usually to represent a ``typewriter'' font) | |
840 | and a face to indicate additional symbols introduced by WoMan. This | |
841 | currently means the characters ^ and _ used to indicate super- and | |
842 | sub-scripts, which are not displayed well by WoMan. | |

899 | easily be directed to follow the reference, i.e.@: to find and format the | |
900 | man page. When the mouse is passed over a correctly formatted reference | |
901 | it is highlighted, in which case clicking the middle button | |
df9d7630 | 902 | @kbd{Mouse-2} will cause WoMan to follow the reference. Alternatively, |

939 | @cindex current man page, changing | |
940 | ||
941 | The man page currently being browsed by WoMan can be changed in several | |
942 | ways. The command @code{woman} can be invoked to format another man | |
943 | page, or the current WoMan buffer can be buried or killed. WoMan | |
944 | maintains a ring of formatted man pages, and it is possible to move | |
945 | forwards and backwards in this ring by moving to the next or previous | |
946 | man page. It is sometimes useful to reformat the current page, for | |
947 | example after the right margin (the wrap column) or some other | |
948 | formatting parameter has been changed. | |
949 | ||
950 | Buffers formatted by Man and WoMan are completely unrelated, even though | |
951 | some of the commands to manipulate them are superficially the same (and | |
952 | share code). | |

955 | @item m | |
956 | @kindex m | |
957 | @findex man | |
958 | Run the command @code{man} to get a Un*x manual page and put it in a | |
959 | buffer. This command is the top-level command in the man package. It | |
960 | runs a Un*x command to retrieve and clean a man page in the background | |
961 | and places the results in a Man mode (man page browsing) buffer. If a | |
962 | man buffer already exists for this man page, it will display | |
963 | immediately. This works exactly the same if WoMan is loaded, except | |

1053 | the option @code{woman-imenu} to @code{t} then WoMan will do it | |

1055 | @code{woman-imenu-title}, which is ``CONTENTS'' by default. The menu | |
1056 | shows manual sections and subsections by default, but you can change | |
1057 | this by customizing @code{woman-imenu-generic-expression}. | |
1058 | ||

1073 | defines a top-level customization group called @code{WoMan} under the | |
1074 | parent group @code{Help}. The WoMan customization group is available | |
1075 | only once WoMan has been loaded unless it is specially set up to be | |

1081 | The top-level WoMan group contains only a few general options and three | |
1082 | subgroups. The hooks are provided only for special purposes that, for | |

1148 | @code{man.*\.conf}. If the environment variable @code{MANPATH} is not | |

1157 | Non-directory and unreadable files are ignored. | |
1158 | ||
1159 | @cindex @code{MANPATH}, environment variable | |
1160 | If not set then the environment variable @code{MANPATH} is used. If no | |
1161 | such environment variable is found, the default list is determined by | |

1163 | expected to be either @file{/etc/man.config} or | |
1164 | @file{/usr/local/lib/man.conf}, which is controlled by the user option | |
1165 | @code{woman-man.conf-path}. An empty substring of @code{MANPATH} | |

1192 | @item woman-manpath-man-regexp | |
1193 | A regular expression to match man directories @emph{under} the | |

1195 | @file{man?}. Its default value is @code{"[Mm][Aa][Nn]"}, which is | |
1196 | case-insensitive mainly for the benefit of Microsoft platforms. Its | |
1197 | purpose is to avoid directories such as @file{cat?}, @file{.}, | |
1198 | @file{..}, etc. | |
1199 | ||
1200 | @item woman-path | |
1201 | A list of strings representing @emph{specific directories} to search for | |

a9212536 EZ |
1203 | |
1204 | @lisp | |
1205 | ("/emacs/etc") | |
1206 | @end lisp | |
1207 | ||
1208 | These directories are searched in addition to the directory trees | |
1209 | specified in @code{woman-manpath}. Each element should be a directory | |
1210 | string or @code{nil}, which represents the current directory when the | |
1211 | path is expanded and cached. However, the last component (only) of each | |
1212 | directory string is treated as a regexp (Emacs, not shell) and the | |
1213 | string is expanded into a list of matching directories. Non-directory | |
1214 | and unreadable files are ignored. The default value on MS-DOS is | |

a9212536 EZ |
1224 | @code{$NAME}, e.g.@: @code{$HOME}, @code{$EMACSDATA}, @code{$EMACS_DIR}, |
1225 | regardless of platform) are evaluated first but each element must | |

1229 | @lisp | |
1230 | ("$EMACSDATA") | |

1237 | ("$EMACS_DIR/etc") | |
1238 | @end lisp | |
1239 | ||
1240 | @noindent | |
1241 | Trailing @file{/}s are discarded. (The directory trees in | |
1242 | @code{woman-manpath} are also searched.) On Microsoft platforms I | |
1243 | recommend including drive letters explicitly. | |
1244 | ||
1245 | @item woman-cache-level | |
1246 | A positive integer representing the level of topic caching: | |
1247 | ||
1248 | @enumerate | |
1249 | @item | |
1250 | cache only the topic and directory lists (uses minimal memory, but not | |
1251 | recommended); | |
1252 | @item | |
1253 | cache also the directories for each topic (faster, without using much | |
1254 | more memory); | |
1255 | @item | |
1256 | cache also the actual filenames for each topic (fastest, but uses twice | |
1257 | as much memory). | |
1258 | @end enumerate | |
1259 | ||
1260 | The default value is currently 2, a good general compromise. If the | |
1261 | @code{woman} command is slow to find files then try 3, which may be | |
1262 | particularly beneficial with large remote-mounted man directories. Run | |
1263 | the @code{woman} command with a prefix argument or delete the cache file | |
1264 | @code{woman-cache-filename} for a change to take effect. (Values < 1 | |
1265 | behave like 1; values > 3 behave like 3.) | |
1266 | ||
1267 | @item woman-cache-filename | |
1268 | Either a string representing the full pathname of the WoMan directory | |
1269 | and topic cache file, or @code{nil}. It is used to save and restore the | |
1270 | cache between Emacs sessions. This is especially useful with | |
1271 | remote-mounted man page files! The default value of @code{nil} | |
256e6c04 | 1272 | suppresses this action. The ``standard'' non-@code{nil} filename is |

1276 | @item woman-dired-keys | |
1277 | A list of @code{dired} mode keys to be defined to run WoMan on the | |

1282 | @item woman-imenu-generic-expression | |
1283 | Imenu support for Sections and Subsections: an alist with elements of | |
a42bec1c | 1284 | the form @code{(MENU-TITLE REGEXP INDEX)}---see the documentation for |
a9212536 EZ |
1285 | @code{imenu-generic-expression}. Default value is |
1286 | ||
1287 | @lisp | |
1288 | ((nil "\n\\([A-Z].*\\)" 1) ; SECTION, but not TITLE | |
1289 | ("*Subsections*" "^ \\([A-Z].*\\)" 1)) | |
1290 | @end lisp | |
1291 | ||
1292 | @item woman-imenu | |
256e6c04 | 1293 | A boolean value that defaults to @code{nil}. If non-@code{nil} then WoMan adds |
a9212536 EZ |
1294 | a Contents menu to the menubar by calling @code{imenu-add-to-menubar}. |
1295 | ||
1296 | @item woman-imenu-title | |
1297 | A string representing the title to use if WoMan adds a Contents menu to | |
1298 | the menubar. Default is @code{"CONTENTS"}. | |
1299 | ||
1300 | @item woman-topic-at-point | |
1301 | A symbol, which may be either @code{t}, @code{nil} or @code{confirm}, | |
1302 | that controls the use by @code{woman} of the ``word at point'' as a | |
256e6c04 | 1303 | topic suggestion. If it is non-@code{nil} then the @code{woman} command uses |
a9212536 EZ |
1304 | the word at point as an initial topic suggestion when it reads a topic |
1305 | from the minibuffer; if it is @code{t} then @code{woman} uses the word | |
1306 | at point @emph{without interactive confirmation} if it exists as a | |
1307 | topic. The value @code{confirm} means suggest a topic and ask for | |
1308 | confirmation. The default value is that of | |
1309 | @code{woman-topic-at-point-default}. | |
1310 | ||
1311 | @item woman-topic-at-point-default | |
1312 | A symbol, which may be either @code{t}, @code{nil} or @code{confirm}, | |
1313 | representing the default value for @code{woman-topic-at-point}. The | |
1314 | default value is @code{confirm}. [The variable | |
1315 | @code{woman-topic-at-point} may be @code{let}-bound when @code{woman} is | |
1316 | loaded, in which case its global value does not get defined. The | |
1317 | function @code{woman-file-name} sets it to this value if it is unbound.] | |
1318 | ||
1319 | @item woman-uncompressed-file-regexp | |
1320 | A regular match expression used to select man source files (ignoring any | |
1321 | compression extension). The default value is | |
1322 | @code{"\\.\\([0-9lmnt]\\w*\\)"} [which means a filename extension is | |
1323 | required]. | |
1324 | ||
1325 | @emph{Do not change this unless you are sure you know what you are doing!} | |
1326 | ||
1327 | The SysV standard man pages use two character suffixes, and this is | |
1328 | becoming more common in the GNU world. For example, the man pages in | |
1329 | the @code{ncurses} package include @file{toe.1m}, @file{form.3x}, etc. | |
1330 | ||
6b61353c KH |
1331 | @strong{Please note:} an optional compression regexp will be appended, |
1332 | so this regexp @emph{must not} end with any kind of string terminator | |
1333 | such as @code{$} or @code{\\'}. | |
a9212536 EZ |
1334 | |
1335 | @item woman-file-compression-regexp | |
1336 | A regular match expression used to match compressed man file extensions | |
1337 | for which decompressors are available and handled by auto-compression | |
1338 | mode. It should begin with @code{\\.} and end with @code{\\'} and | |
1339 | @emph{must not} be optional. The default value is | |
1340 | @code{"\\.\\(g?z\\|bz2\\)\\'"}, which matches the @code{gzip} and | |
1341 | @code{bzip2} compression extensions. | |
1342 | ||
1343 | @emph{Do not change this unless you are sure you know what you are doing!} | |
1344 | ||
1345 | [It should be compatible with the @code{car} of | |
1346 | @code{jka-compr-file-name-handler-entry}, but that is unduly | |
1347 | complicated, includes an inappropriate extension (@file{.tgz}) and is | |
1348 | not loaded by default!] | |
1349 | ||
1350 | @item woman-use-own-frame | |
256e6c04 | 1351 | If non-@code{nil} then use a dedicated frame for displaying WoMan windows. |
a9212536 EZ |
1352 | This is useful only when WoMan is run under a window system such as X or |
1353 | Microsoft Windows that supports real multiple frames, in which case the | |

1416 | @item woman-italic-face | |
1417 | Face for italic font in man pages. Default: italic, underlined, | |

1419 | @code{NROFF} uses just underline. You should probably select either | |
1420 | italic or underline as you prefer, but not both, although italic and | |

1443 | This section currently applies @emph{only} to Microsoft Windows. | |
1444 | ||
1445 | WoMan provides partial experimental support for special symbols, | |
1446 | initially only for MS-Windows and only for MS-Windows fonts. This | |
6b61353c | 1447 | includes both non-@acronym{ASCII} characters from the main text font and use |
a9212536 EZ |
1448 | of a separate symbol font. Later, support will be added for other font |
1449 | types (e.g.@: @code{bdf} fonts) and for the X Window System. In Emacs | |
1450 | 20.7, the current support works partially under Windows 9x but may not | |

1456 | from the default font. Default is @code{t}. |
1457 | ||
1458 | @item woman-use-symbol-font | |
256e6c04 | 1459 | A boolean value. If non-@code{nil} then WoMan may use the symbol font. |
a9212536 EZ |
1460 | Default is @code{nil}, mainly because it may change the line spacing (at |
1461 | least in NTEmacs 20). | |
1462 | ||
1463 | @item woman-symbol-font | |
1464 | A string describing the symbol font to use for special characters. | |

1480 | @cindex buffer, log | |
1481 | ||
28665d46 | 1482 | This is modeled on the Emacs byte-compiler. It logs all files |
a9212536 EZ |
1483 | formatted by WoMan and the time taken. If WoMan finds anything that it |
1484 | cannot handle then it writes a warning to this buffer. If the variable | |
256e6c04 | 1485 | @code{woman-show-log} is non-@code{nil} (by default it is @code{nil}) then |
a9212536 EZ |
1486 | WoMan automatically displays this buffer. @xref{Interface Options, , |
1487 | Interface Options}. Many WoMan warnings can be completely ignored, | |
1488 | because they are reporting the fact that WoMan has ignored requests that | |
1489 | it is correct for WoMan to ignore. In some future version this level of | |
1490 | paranoia may be reduced, but not until WoMan is deemed more reliable. | |
1491 | At present, all warnings should be treated with some suspicion. | |
1492 | Uninterpreted escape sequences are also logged (in some cases). | |
1493 | ||
1494 | By resetting the variable @code{woman-ignore} to @code{nil} (by default | |
1495 | it is @code{t}), uninterpreted @code{ROFF} requests can optionally be | |
1496 | left in the formatted buffer to indicate precisely where they occurred. | |

1512 | WoMan currently assumes 10 characters per inch horizontally, hence a | |

1517 | @heading Vertical spacing and blank lines | |
1518 | ||
1519 | The number of consecutive blank lines in the formatted buffer should be | |
