57 | % \section{Introduction and user guide} |
58 | % |
59 | % This file is really rather strange; it gets |\input| by other package |
60 | % documentation files to set up most of the environmental gubbins for them. |
61 | % It handles almost everything, like loading a document class, finding any |
62 | % packages, and building and formatting the title. |
63 | % |
64 | % It also offers an opportunity for users to customise my nice documentation, |
65 | % by using a |mdwtools.cfg| file (not included). |
66 | % |
67 | % |
68 | % \subsection{Declarations} |
69 | % |
70 | % A typical documentation file contains something like |
71 | % \begin{listinglist} \listingsize \obeylines |
72 | % |\input{mdwtools}| |
73 | % \<declarations> |
74 | % |\mdwdoc| |
75 | % \end{listinglist} |
76 | % The initial |\input| reads in this file and sets up the various commands |
77 | % which may be needed. The final |\mdwdoc| actually starts the document, |
78 | % inserting a title (which is automatically generated), a table of |
79 | % contents etc., and reads the documentation file in (using the |\DocInput| |
80 | % command from the \package{doc} package. |
81 | % |
82 | % \subsubsection{Describing packages} |
83 | % |
84 | % \DescribeMacro{\describespackage} |
85 | % \DescribeMacro{\describesclass} |
86 | % \DescribeMacro{\describesfile} |
87 | % \DescribeMacro{\describesfile*} |
88 | % The most important declarations are those which declare what the |
89 | % documentation describes. Saying \syntax{"\\describespackage{<package>}"} |
90 | % loads the \<package> (if necessary) and adds it to the auto-generated |
91 | % title, along with a footnote containing version information. Similarly, |
92 | % |\describesclass| adds a document class name to the title (without loading |
93 | % it -- the document itself must do this, with the |\documentclass| command). |
94 | % For files which aren't packages or classes, use the |\describesfile| or |
95 | % |\describesfile*| command (the $*$-version won't |\input| the file, which |
96 | % is handy for files like |mdwtools.tex|, which are already input). |
97 | % |
98 | % \DescribeMacro{\author} |
99 | % \DescribeMacro{\date} |
100 | % \DescribeMacro{\title} |
101 | % The |\author|, |\date| and |\title| declarations work slightly differently |
102 | % to normal -- they ensure that only the \emph{first} declaration has an |
103 | % effect. (Don't you play with |\author|, please, unless you're using this |
104 | % program to document your own packages.) Using |\title| suppresses the |
105 | % automatic title generation. |
106 | % |
107 | % \DescribeMacro{\docdate} |
108 | % The default date is worked out from the version string of the package or |
109 | % document class whose name is the same as that of the documentation file. |
110 | % You can choose a different `main' file by saying |
111 | % \syntax{"\\docdate{"<file>"}"}. |
112 | % |
113 | % \subsubsection{Contents handling} |
114 | % |
115 | % \DescribeMacro{\addcontents} |
116 | % A documentation file always has a table of contents. Other |
117 | % contents-like lists can be added by saying |
118 | % \syntax{"\\addcontents{"<extension>"}{"<command>"}"}. The \<extension> |
119 | % is the file extension of the contents file (e.g., \lit{lot} for the |
120 | % list of tables); the \<command> is the command to actually typeset the |
121 | % contents file (e.g., |\listoftables|). |
122 | % |
123 | % \subsubsection{Other declarations} |
124 | % |
125 | % \DescribeMacro{\implementation} |
126 | % The \package{doc} package wants you to say |
127 | % \syntax{"\\StopEventually{"<stuff>"}"}' before describing the package |
128 | % implementation. Using |mdwtools.tex|, you just say |\implementation|, and |
129 | % everything works. It will automatically read in the licence text (from |
130 | % |gpl.tex|, and wraps some other things up. |
131 | % |
e8e9e5d8 |
132 | % |
86f6a31e |
133 | % \subsection{Other commands} |
134 | % |
135 | % The |mdwtools.tex| file includes the \package{syntax} and \package{sverb} |
136 | % packages so that they can be used in documentation files. It also defines |
137 | % some trivial commands of its own. |
138 | % |
139 | % \DescribeMacro{\<} |
140 | % Saying \syntax{"\\<"<text>">" is the same as "\\synt{"<text>"}"}; this |
141 | % is a simple abbreviation. |
142 | % |
143 | % \DescribeMacro{\smallf} |
144 | % Saying \syntax{"\\smallf" <number>"/"<number>} typesets a little fraction, |
145 | % like this: \smallf 3/4. It's useful when you want to say that the default |
146 | % value of a length is 2 \smallf 1/2\,pt, or something like that. |
147 | % |
148 | % |
149 | % \subsection{Customisation} |
150 | % |
151 | % You can customise the way that the package documentation looks by writing |
152 | % a file called |mdwtools.cfg|. You can redefine various commands (before |
153 | % they're defined here, even; |mdwtools.tex| checks most of the commands that |
154 | % it defines to make sure they haven't been defined already. |
155 | % |
156 | % \DescribeMacro{\indexing} |
157 | % If you don't want the prompt about whether to generate index files, you |
158 | % can define the |\indexing| command to either \lit{y} or \lit{n}. I'd |
159 | % recommend that you use |\providecommand| for this, to allow further |
160 | % customisation from the command line. |
161 | % |
162 | % \DescribeMacro{\mdwdateformat} |
163 | % If you don't like my date format (maybe you're American or something), |
164 | % you can redefine the |\mdwdateformat| command. It takes three arguments: |
165 | % the year, month and date, as numbers; it should expand to something which |
166 | % typesets the date nicely. The default format gives something like |
167 | % `10 May 1996'. You can produce something rather more exotic, like |
168 | % `10\textsuperscript{th} May \textsc{\romannumeral 1996}' by saying |
169 | %\begin{listing} |
170 | %\newcommand{\mdwdateformat}[3]{% |
171 | % \number#3\textsuperscript{\numsuffix{#3}}\ % |
172 | % \monthname{#2}\ % |
173 | % \textsc{\romannumeral #1}% |
174 | %} |
175 | %\end{listing} |
176 | % \DescribeMacro{\monthname} |
177 | % \DescribeMacro{\numsuffix} |
178 | % Saying \syntax{"\\monthname{"<number>"}"} expands to the name of the |
179 | % numbered month (which can be useful when doing date formats). Saying |
180 | % \syntax{"\\numsuffix{"<number>"}"} will expand to the appropriate suffix |
181 | % (`th' or `rd' or whatever) for the \<number>. You'll have to superscript |
182 | % it yourself, if this is what you want to do. Putting the year number |
183 | % in roman numerals is just pretentious |;-)|. |
184 | % |
185 | % \DescribeMacro{\mdwhook} |
186 | % After all the declarations in |mdwtools.tex|, the command |\mdwhook| is |
187 | % executed, if it exists. This can be set up by the configuration file |
188 | % to do whatever you want. |
189 | % |
190 | % There are lots of other things you can play with; you should look at the |
191 | % implementation section to see what's possible. |
192 | % |
193 | % \implementation |

197 | % \begin{macrocode} |
198 | %<*mdwtools> |
199 | % \end{macrocode} |
200 | % |
201 | % The first thing is that I'm not a \LaTeX\ package or anything official |
202 | % like that, so I must enable `|@|' as a letter by hand. |
203 | % |
204 | % \begin{macrocode} |
205 | \makeatletter |
206 | % \end{macrocode} |
207 | % |
208 | % Now input the user's configuration file, if it exists. This is fairly |
209 | % simple stuff. |
210 | % |
211 | % \begin{macrocode} |
212 | \@input{mdwtools.cfg} |
213 | % \end{macrocode} |
214 | % |
215 | % Well, that's the easy bit done. |
216 | % |
217 | % |
218 | % \subsection{Initialisation} |
219 | % |
220 | % Obviously the first thing to do is to obtain a document class. Obviously, |
221 | % it would be silly to do this if a document class has already been loaded, |
222 | % either by the package documentation or by the configuration file. |
223 | % |
224 | % The only way I can think of for finding out if a document class is already |
225 | % loaded is by seeing if the |\documentclass| command has been redefined |
226 | % to raise an error. This isn't too hard, really. |
227 | % |
228 | % \begin{macrocode} |
229 | \ifx\documentclass\@twoclasseserror\else |
230 | \documentclass[a4paper]{ltxdoc} |
231 | \ifx\doneclasses\mdw@undefined\else\doneclasses\fi |
232 | \fi |
233 | % \end{macrocode} |
234 | % |
235 | % As part of my standard environment, I'll load some of my more useful |
236 | % packages. If they're already loaded (possibly with different options), |
237 | % I'll not try to load them again. |
238 | % |
239 | % \begin{macrocode} |
240 | \@ifpackageloaded{doc}{}{\usepackage{doc}} |
241 | \@ifpackageloaded{syntax}{}{\usepackage[rounded]{syntax}} |
242 | \@ifpackageloaded{sverb}{}{\usepackage{sverb}} |
243 | % \end{macrocode} |
244 | % |
245 | % |
246 | % \subsection{Some macros for interaction} |
247 | % |
248 | % I like the \LaTeX\ star-boxes, although it's a pain having to cope with |
249 | % \TeX's space-handling rules. I'll define a new typing-out macro which |
250 | % makes spaces more significant, and has a $*$-version which doesn't put |
251 | % a newline on the end, and interacts prettily with |\read|. |
252 | % |
253 | % First of all, I need to make spaces active, so I can define things about |
254 | % active spaces. |
255 | % |
256 | % \begin{macrocode} |
257 | \begingroup\obeyspaces |
258 | % \end{macrocode} |
259 | % |
260 | % Now to define the main macro. This is easy stuff. Spaces must be |
261 | % carefully rationed here, though. |
262 | % |
263 | % I'll start a group, make spaces active, and make spaces expand to ordinary |
264 | % space-like spaces. Then I'll look for a star, and pass either |\message| |
265 | % (which doesn't start a newline, and interacts with |\read| well) or |
266 | % |\immediate\write 16| which does a normal write well. |
267 | % |
268 | % \begin{macrocode} |
269 | \gdef\mdwtype{% |
270 | \begingroup\catcode`\ \active\let \space% |
271 | \@ifstar{\mdwtype@i{\message}}{\mdwtype@i{\immediate\write\sixt@@n}}% |
272 | } |
273 | \endgroup |
274 | % \end{macrocode} |
275 | % |
276 | % Now for the easy bit. I have the thing to do, and the thing to do it to, |
277 | % so do that and end the group. |
278 | % |
279 | % \begin{macrocode} |
280 | \def\mdwtype@i#1#2{#1{#2}\endgroup} |
281 | % \end{macrocode} |
282 | % |
283 | % |
284 | % \subsection{Decide on indexing} |
285 | % |
286 | % A configuration file can decide on indexing by defining the |\indexing| |
287 | % macro to either \lit{y} or \lit{n}. If it's not set, then I'll prompt |
288 | % the user. |
289 | % |
290 | % First of all, I want a switch to say whether I'm indexing. |
291 | % |
292 | % \begin{macrocode} |
293 | \newif\ifcreateindex |
294 | % \end{macrocode} |
295 | % |
296 | % Right: now I need to decide how to make progress. If the macro's not set, |
297 | % then I want to set it, and start a row of stars. |
298 | % |
299 | % \begin{macrocode} |
300 | \ifx\indexing\@@undefined |
301 | \mdwtype{*****************************} |
302 | \def\indexing{?} |
303 | \fi |
304 | % \end{macrocode} |
305 | % |
306 | % Now enter a loop, asking the user whether to do indexing, until I get |
307 | % a sensible answer. |
308 | % |
309 | % \begin{macrocode} |
310 | \loop |
311 | \@tempswafalse |
312 | \if y\indexing\@tempswatrue\createindextrue\fi |
313 | \if Y\indexing\@tempswatrue\createindextrue\fi |
314 | \if n\indexing\@tempswatrue\createindexfalse\fi |
315 | \if N\indexing\@tempswatrue\createindexfalse\fi |
316 | \if@tempswa\else |
317 | \mdwtype*{* Create index files? (y/n) *} |
318 | \read\sixt@@n to\indexing% |
319 | \repeat |
320 | % \end{macrocode} |
321 | % |
322 | % Now, based on the results of that, display a message about the indexing. |
323 | % |
324 | % \begin{macrocode} |
325 | \mdwtype{*****************************} |
326 | \ifcreateindex |
327 | \mdwtype{* Creating index files *} |
328 | \mdwtype{* This may take some time *} |
329 | \else |
330 | \mdwtype{* Not creating index files *} |
331 | \fi |
332 | \mdwtype{*****************************} |
333 | % \end{macrocode} |
334 | % |
335 | % Now I can play with the indexing commands of the \package{doc} package |
336 | % to do whatever it is that the user wants. |
337 | % |
338 | % \begin{macrocode} |
339 | \ifcreateindex |

344 | \DisableCrossrefs |
345 | \fi |
346 | % \end{macrocode} |
347 | % |
348 | % And register lots of plain \TeX\ things which shouldn't be indexed. |
349 | % This contains lots of |\if|\dots\ things which don't fit nicely in |
350 | % conditionals, which is a shame. Still, it doesn't matter that much, |
351 | % really. |
352 | % |
353 | % \begin{macrocode} |
354 | \DoNotIndex{\def,\long,\edef,\xdef,\gdef,\let,\global} |
355 | \DoNotIndex{\if,\ifnum,\ifdim,\ifcat,\ifmmode,\ifvmode,\ifhmode,% |
356 | \iftrue,\iffalse,\ifvoid,\ifx,\ifeof,\ifcase,\else,\or,\fi} |
357 | \DoNotIndex{\box,\copy,\setbox,\unvbox,\unhbox,\hbox,% |
358 | \vbox,\vtop,\vcenter} |
359 | \DoNotIndex{\@empty,\immediate,\write} |
360 | \DoNotIndex{\egroup,\bgroup,\expandafter,\begingroup,\endgroup} |
361 | \DoNotIndex{\divide,\advance,\multiply,\count,\dimen} |
362 | \DoNotIndex{\relax,\space,\string} |
363 | \DoNotIndex{\csname,\endcsname,\@spaces,\openin,\openout,% |

365 | \DoNotIndex{\catcode,\endinput} |
366 | \DoNotIndex{\jobname,\message,\read,\the,\m@ne,\noexpand} |

368 | \DoNotIndex{\m@ne,\z@,\z@skip,\@ne,\tw@,\p@} |
369 | \DoNotIndex{\dp,\wd,\ht,\vss,\unskip} |
370 | % \end{macrocode} |
371 | % |
372 | % Last bit of indexing stuff, for now: I'll typeset the index in two columns |
373 | % (the default is three, which makes them too narrow for my tastes). |
374 | % |
375 | % \begin{macrocode} |
376 | \setcounter{IndexColumns}{2} |
377 | % \end{macrocode} |
378 | % |
379 | % |
380 | % \subsection{Selectively defining things} |
381 | % |
382 | % I don't want to tread on anyone's toes if they redefine any of these |
383 | % commands and things in a configuration file. The following definitions |
384 | % are fairly evil, but should do the job OK. |
385 | % |
386 | % \begin{macro}{\@gobbledef} |
387 | % |
388 | % This macro eats the following |\def|inition, leaving not a trace behind. |
389 | % |
390 | % \begin{macrocode} |
391 | \def\@gobbledef#1#{\@gobble} |
392 | % \end{macrocode} |

394 | % \end{macro} |
395 | % |
396 | % \begin{macro}{\tdef} |
397 | % \begin{macro}{\tlet} |
398 | % |
399 | % The |\tdef| command is a sort of `tentative' definition -- it's like |
400 | % |\def| if the control sequence named doesn't already have a definition. |
401 | % |\tlet| does the same thing with |\let|. |
402 | % |
403 | % \begin{macrocode} |
404 | \def\tdef#1{ |
405 | \ifx#1\@@undefined% |
406 | \expandafter\def\expandafter#1% |

413 | % |
414 | % \end{macro} |
415 | % \end{macro} |
416 | % |
417 | % |
418 | % \subsection{General markup things} |
419 | % |
420 | % Now for some really simple things. I'll define how to typeset package |
421 | % names and environment names (both in the sans serif font, for now). |
422 | % |
423 | % \begin{macrocode} |
424 | \tlet\package\textsf |
425 | \tlet\env\textsf |
426 | % \end{macrocode} |

431 | % \begin{macrocode} |
432 | \tdef\<#1>{\synt{#1}} |
433 | % \end{macrocode} |
434 | % |
435 | % And because it's used in a few places (mainly for typesetting lengths), |
436 | % here's a command for typesetting fractions in text. |
437 | % |
438 | % \begin{macrocode} |
439 | \tdef\smallf#1/#2{\ensuremath{^{#1}\!/\!_{#2}}} |

444 | % |
445 | % \begin{environment}{tab} |
446 | % |
447 | % Most of the packages don't use the (obviously perfect) \package{mdwtab} |
448 | % package, because it's big, and takes a while to load. Here's an |
449 | % environment for typesetting centred tables. The first (optional) argument |

522 | % Also make \TeX\ shut up in the index. The \package{multicol} package |
523 | % irritatingly plays with |\hbadness|. This is the best hook I could find |

553 | % \subsection{Contents handling} |
554 | % |
555 | % I use at least one contents file (the main table of contents) although |
556 | % I may want more. I'll keep a list of contents files which I need to |
557 | % handle. |
558 | % |
559 | % There are two things I need to do to contents files here: |
560 | % \begin{itemize} |
561 | % \item I must typeset the table of contents at the beginning of the |
562 | % document; and |
563 | % \item I want to typeset tables of contents in two columns (using the |
564 | % \package{multicol} package). |
565 | % \end{itemize} |
566 | % |
567 | % The list consists of items of the form |
568 | % \syntax{"\\do{"<extension>"}{"<command>"}"}, where \<extension> is the |
569 | % file extension of the contents file, and \<command> is the command to |
570 | % typeset it. |
571 | % |
572 | % \begin{macro}{\docontents} |
573 | % |
574 | % This is where I keep the list of contents files. I'll initialise it to |
575 | % just do the standard contents table. |
576 | % |
577 | % \begin{macrocode} |
578 | \def\docontents{\do{toc}{\tableofcontents}} |
579 | % \end{macrocode} |
580 | % |
581 | % \end{macro} |
582 | % |
583 | % \begin{macro}{\addcontents} |
584 | % |
585 | % By saying \syntax{"\\addcontents{"<extension>"}{"<command>"}"}, a document |
586 | % can register a new table of contents which gets given the two-column |
587 | % treatment properly. This is really easy to implement. |
588 | % |
589 | % \begin{macrocode} |
590 | \def\addcontents#1#2{% |
591 | \toks@\expandafter{\docontents\do{#1}{#2}}% |

599 | % \subsection{Finishing it all off} |
600 | % |
601 | % \begin{macro}{\finalstuff} |
602 | % |
603 | % The |\finalstuff| macro is a hook for doing things at the end of the |
604 | % document. Currently, it inputs the licence agreement as an appendix. |
605 | % |
606 | % \begin{macrocode} |
607 | \tdef\finalstuff{\appendix\part*{Appendix}\input{gpl}} |
608 | % \end{macrocode} |
609 | % |
610 | % \end{macro} |
611 | % |
612 | % \begin{macro}{\implementation} |
613 | % |
614 | % The |\implementation| macro starts typesetting the implementation of |
615 | % the package(s). If we're not doing the implementation, it just does |
616 | % this lot and ends the input file. |
617 | % |
618 | % I define a macro with arguments inside the |\StopEventually|, which causes |
619 | % problems, since the code gets put through an extra level of |\def|fing |
620 | % depending on whether the implementation stuff gets typeset or not. I'll |
621 | % store the code I want to do in a separate macro. |
622 | % |
623 | % \begin{macrocode} |
624 | \def\implementation{\StopEventually{\attheend}} |
625 | % \end{macrocode} |
626 | % |
627 | % Now for the actual activity. First, I'll do the |\finalstuff|. Then, if |
628 | % \package{doc}'s managed to find the \package{multicol} package, I'll add |
629 | % the end of the environment to the end of each contents file in the list. |
630 | % Finally, I'll read the index in from its formatted |.ind| file. |
631 | % |

646 | % \subsection{File version information} |
647 | % |
648 | % \begin{macro}{\mdwpkginfo} |
649 | % |
650 | % For setting up the automatic titles, I'll need to be able to work out |
651 | % file versions and things. This macro will, given a file name, extract |
652 | % from \LaTeX\ the version information and format it into a sensible string. |
653 | % |
654 | % First of all, I'll put the original string (direct from the |
655 | % |\Provides|\dots\ command). Then I'll pass it to another macro which can |
656 | % parse up the string into its various bits, along with the original |
657 | % filename. |
658 | % |
659 | % \begin{macrocode} |
660 | \def\mdwpkginfo#1{% |

662 | \expandafter\mdwpkginfo@i\@tempa\@@#1\@@% |
663 | } |
664 | % \end{macrocode} |
665 | % |
666 | % Now for the real business. I'll store the string I build in macros called |
667 | % \syntax{"\\"<filename>"date", "\\"<filename>"version" and |
668 | % "\\"<filename>"info"}, which store the file's date, version and |
669 | % `information string' respectively. (Note that the file extension isn't |
670 | % included in the name.) |
671 | % |
672 | % This is mainly just tedious playing with |\expandafter|. The date format |
673 | % is defined by a separate macro, which can be modified from the |
674 | % configuration file. |

865 | % |
866 | % \begin{macro}{\author} |
