124 <h2><a name="introduction" id="introduction"></a>Introduction</h2>
125
126 <p>Boost places no requirements on the design of HTML documentation for
127 library submitters. If you are submitting a library for which documentation
128 already exists in either HTML or in a form easily converted to HTML then
129 there is no need for you to read this document. However, if you have not
130 yet written the documentation, or if you expect to have to translate
131 documentation written in a format not easily convertible to HTML then this
132 document can give you a lot of information on how to go about writing
133 documentation in HTML.</p>
134
135 <p>In several places this document assumes you're writing the documentation
136 to conform to the structure described in the <a href=
137 "structure.html">Documentation Structure</a> document. There is no
138 requirement that your documentation content follow these guidelines, but
139 they provide an effective way to communicate technical specifications for a
140 library in a terse yet precise manner that's familiar to many Boost
141 users.</p>
142
143 <p>This document also contains links to <a href="#templates">HTML template
144 files</a> that can be used to rapidly develop documentation for a library
145 submission. These templates follow the guidelines presented here and in the
146 <a href="structure.html">Documentation Structure</a> document.</p>
147
148 <h2><a name="common-pages" id="common-pages"></a>Common Pages Included in
149 HTML Documentation</h2>
150
151 <p>Most HTML documentation projects will contain some common pages. General
152 guidelines for these common pages are provided below.</p>
153
154 <h3><a name="index-page" id="index-page"></a>Index</h3>
155
156 <p>The index page is the first page presented to a user when he browses the
157 documentation. Generally this page should not contain any actual content,
158 but instead contains a list of links to specific content. At a minimum this
159 list should contain a link to every HTML page contained in the
160 documentation. Optionally, sub-lists may be provided for individual pages
161 linking to specific subjects within the page. These sub-lists should form a
162 "tree" hierarchy based on the level of heading tag used for the specific
163 subject. Inclusion of such sub-lists for every page can make the index
164 rather lengthy, and since each page should include its own <a href=
165 "#page-index">Page Index</a>, it may make the navigation of the
166 documentation easier if such sub-lists are avoided. However, there is one
167 exception to this guideline: reference documentation should contain a link
168 to every header file in the library and a sub-list with a link to every
169 macro, value, type, class, function and object (see <a href=
170 "structure.html">Documentation Structure</a>) found in the header. Users
171 aren't always sure what header file any of these may be contained in, so
172 this structure in the index allows for easy navigation of the reference
173 documentation.</p>
174
175 <p>The index list should generally be constructed using an HTML "definition
176 list" (&lt;dl&gt; and &lt;dt&gt; tags). A definition list has no bullets or
177 ordered specifications and produces a cleaner layout then an unordered list
178 (&lt;ul&gt; and &lt;li&gt; tags) or an ordered list (&lt;ol&gt; and
179 &lt;li&gt; tags). If you choose to use the common <a href=
180 "#boost-style-sheet">Boost Style Sheet</a> you should add a
181 <code>class="index"</code> attribute/value pair to the &lt;dl&gt; tag.</p>
182
183 <p>An Index page <a href="#index-template">template</a> is provided for
184 use.</p>
185
186 <h3><a name="overview-page" id="overview-page"></a>Overview</h3>
187
188 <p>The Overview page is used to introduce the reader to the library. It
189 should give a high-level overview of the purpose of the library and
190 introduce the reader to any concepts they may be unfamiliar with. This may
191 also be an appropriate place for some "light" rationale, though more
192 thorough presentation of any rationale would be better placed in the
193 <a href="#rationale-page">Rational Page</a>.</p>
194
195 <p>Like most content pages, the Overview page should include a <a href=
196 "#page-index">Page Index</a>.</p>
197
198 <p>An Overview page <a href="#overview-template">template</a> is provided
199 for use.</p>
200
201 <h3><a name="definitions-page" id="definitions-page"></a>Definitions</h3>
202
203 <p>The Definitions page is used to provide a list of definitions for terms
204 that a user may be unfamiliar with.</p>
205
206 <p>The definition list should generally be constructed using an HTML
207 "definition list" (&lt;dl&gt; and &lt;DT&gt; tags). A definition list has
208 no bullets or ordered specifications and produces a cleaner layout then an
209 unordered list (&lt;UL&gt; and &lt;li&gt; tags) or an ordered list
210 (&lt;ol&gt; and &lt;li&gt; tags). If you choose to use the common <a href=
211 "#boost-style-sheet">Boost Style Sheet</a> you should add a
212 <code>class="definition"</code> attribute/value pair to the &lt;dl&gt;
213 tag.</p>
214
215 <p>Because this page's content should only contain a list of definitions,
216 it should not have a <a href="#page-index">Page Index</a>.</p>
217
218 <p>A Definitions page <a href="#definitions-template">template</a> is
219 provided for use.</p>
220
221 <h3><a name="rationale-page" id="rationale-page"></a>Rationale</h3>
222
223 <p>The Rationale page is used to provide lengthy descriptions of the
224 rationale behind the library's design. This information helps users to
225 understand why a library was designed the way it was and may reduce the
226 frequency of a number of frequently asked questions. For a better
227 description of why rationale is important see the <a href=
228 "http://www.boost.org/more/lib_guide.htm#Rationale">Rationale rationale</a>
229 in the general submission guidelines.</p>
230
231 <p>Like most content pages, the Rationale page should include a <a href=
232 "#page-index">Page Index</a>.</p>
233
234 <p>A Rationale page <a href="#rationale-template">template</a> is provided
235 for use.</p>
236
237 <h3><a name="configuration-page" id="configuration-page"></a>Configuration
238 Information</h3>
239
240 <p>The Configuration Information page is used to document configuration
241 macros used by the library. Such macros belong in one of three groups:
242 macros used by library implenters defined in
243 <code>&lt;boost/config.hpp&gt;</code>, macros used by library users to
244 detect platform configuration information and macros defined by library
245 users to configure library behavior.</p>
246
247 <p>Like most content pages, the Overview page should include a <a href=
248 "#page-index">Page Index</a>.</p>
249
250 <p>A Configuration page <a href="#configuration-template">template</a> is
251 provided for use.</p>
252
253 <h3><a name="faq-page" id="faq-page"></a>Frequently Asked Questions</h3>
254
255 <p>As a library matures the users will have questions about the usage of
256 the library. Often users will ask the same questions over and over again.
257 Rather than having to deal with answering the question every time it's
258 asked, a Frequently Asked Questions (commonly known as FAQs) page can be
259 used to document the questions and answers. This is such a valuable piece
260 of documentation not only for the users but for the maintainers as well,
261 that a FAQ page should be provided from the outset. If there are no
262 questions that will obviously become a FAQ, the initial page may just
263 indicate that there are no FAQs yet. This empty place holder helps to
264 indicate to the users that you plan to address any FAQs as they occur.</p>
265
266 <p>The <a href="#page-index">Page Index</a> for the FAQ page should contain
267 a list of all the questions contained in the document. The actual question
268 entries should be formatted with the question in a heading tag and the
269 answers in standard paragraph format. This provides a clean presentation
270 that's easy to read.</p>
271
272 <p>A Frequently Asked Questions page <a href="#faq-template">template</a>
273 is provided for use.</p>
274
275 <h3><a name="bibliography-page" id=
276 "bibliography-page"></a>Bibliography</h3>
277
278 <p>The Bibliography page is used to document any bibliographical
279 information associated with references made within the documentation to
280 external resources. Parenthetical references are used within the
281 documentation which link to entries in the Bibliography page.
282 Bibliographical entries provide detailed information about the external
283 resource and may contain hyper links to the resource if it's available
284 online. There are several formal styles used for writing bibliographies.
285 You may use what ever style you want, but one of the better styles to
286 consider using can be referenced <a href=
287 "http://www.columbia.edu/cu/cup/cgos/idx_basic.html">here</a>.</p>
288
289 <p>Since the Bibliography page should contain only bibliographical
290 information there is no need for a <a href="#page-index">Page
291 Index</a>.</p>
292
293 <p>A Bibliography page <a href="#bibliography-template">template</a> is
294 provided for use.</p>
295
296 <h3><a name="acknowledgements-page" id=
297 "acknowledgements-page"></a>Acknowledgment</h3>
298
299 <p>The Acknowledgment page is used to give credit where credit is due. When
300 individuals provide input on the design or implementation, or when you make
301 use of someone else's work, you should acknowledge them. This is a courtesy
302 that you'd expect others to extend to you, so you should strive to
303 acknowledge the efforts of everyone else in your own documentation.</p>
304
305 <p>Since the Acknowledgment page should contain only a list of
306 acknowledgment there is no need for a <a href="#page-index">Page
307 Index</a>.</p>
308
309 <p>An Acknowledgments page <a href=
310 "#acknowledgements-template">template</a> is provided for use.</p>
311
312 <h3><a name="header-page" id="header-page"></a>Header Reference</h3>
313
314 <p>The Header Reference pages are the most important pages in your
315 documentation. They document all library headers, including all the macros,
316 values, types, classes, functions and objects defined in them. In general
317 it may prove useful to follow the guidelines in <a href=
318 "structure.html">Documentation Structure</a> when writing the content for
319 these pages.</p>
320
321 <p>Like most content pages, the Header Reference pages should include a
322 <a href="#page-index">Page Index</a>.</p>
323
324 <p>A Header Reference page <a href="#header-template">template</a> is
325 provided for use.</p>
326
327 <h2><a name="layout" id="layout"></a>Layout</h2>
328
329 <p>There are certain page layout concepts that will be used frequently in
330 many of your pages. This section outlines some general guidelines that you
331 can follow when designing each of these layout concepts for your
332 documentation.</p>
333
334 <h3><a name="page-banner" id="page-banner"></a>Page Banner</h3>
335
336 <p>The Page Banner is located at the very top of a page and provides quick
337 information about the page contents. This includes the Boost logo, which
338 indicates to the reader that this page is part of the Boost web site, a
339 title for the documentation (generally the library name) and the page
340 title. The Boost logo should hyper link to the Boost home page on the index
341 page and to the index page on all other pages. This allows the user to
342 easily navigate through the Boost web site and through the documentation.
343 The &lt;title&gt; tag for the HTML page should consist of the documentation
344 title and the page title separated by a hyphen.</p>
345
346 <p>The Page Banner should be separated from the rest of the page by the use
347 of an &lt;hr&gt; tag. This helps to clearly separate the actual content
348 from the title information and produces cleaner text.</p>
349
350 <h3><a name="page-index" id="page-index"></a>Page Index</h3>
351
352 <p>The page index is used to quickly navigate to the various sections of
353 the documentation on the page, and when present should be located just
354 below the Page Banner.</p>
355
356 <p>The index list should generally be constructed using an HTML "definition
357 list" (&lt;dl&gt; and &lt;DT&gt; tags). A definition list has no bullets or
358 ordered specifications and produces a cleaner layout then an unordered list
359 (&lt;UL&gt; and &lt;li&gt; tags) or an ordered list (&lt;ol&gt; and
360 &lt;li&gt; tags). If you choose to use the Boost Style Sheet you should add
361 a <code>class="page-index"</code> attribute/value pair to the &lt;dl&gt;
362 tag.</p>
363
364 <p>Most pages should include a Page Index.</p>
365
366 <h3><a name="content" id="content"></a>Documentation Content</h3>
367
368 <p>The page's actual documentation content will be formatted according to
369 the specific needs of individual pages, and should be placed right after
370 the Page Index if present, or after the Page Banner if not. In general the
371 documentation content will take the form of paragraph text contained
372 underneath section headings.</p>
373
374 <h3><a name="doc-footnotes" id="doc-footnotes"></a>Footnotes</h3>
375
376 <p>Footnotes may be used within a page's documentation. Within the
377 documentation content a footnote reference should take the form of a
378 footnote number in parentheses (the parentheses make it easier for the
379 reader to click on the hyper link) hyper linking to the actual footnote at
380 the bottom of the page's documentation content. You may either use the
381 &lt;sup&gt; tag to format such footnote numbers, or, preferably, you can
382 use a CSS style class in order to distinguish the number as a footnote
383 instead of as part of the actual text. If you choose to use the common
384 <a href="#boost-style-sheet">Boost Style Sheet</a>, a <code>footnote</code>
385 class is defined for this purpose.</p>
386
387 <h3><a name="revision-info" id="revision-info"></a>Revision
388 Information</h3>
389
390 <p>At the bottom of every page should be some revision information
391 indicating when the page was last revised. This information should be
392 separated from the rest of the page above by an &lt;hr&gt; tag. The
393 following HTML code snippet can be used to track this revision information
394 (this code uses some server components that exist on the Boost web site to
395 automatically track revision dates with out the need for hand editing the
396 date text):</p>
397 <pre>
398 &lt;hr&gt;
399 &lt;p&gt;Revised
400 &lt;!--webbot bot="Timestamp" S-Type="EDITED" S-Format="%d %B, %Y" startspan --&gt;
401 01 January, 2001
402 &lt;!--webbot bot="Timestamp" endspan i-checksum="39359" --&gt;
403 &lt;/p&gt;
404 </pre>
405
406 <h3><a name="copyright" id="copyright"></a>Copyright Information</h3>
407
408 <p>The very bottom of the page should contain any copyright information
409 that applies to the document.</p>
410
411 <h2><a name="format" id="format"></a>Format</h2>
412
413 <p>This section provides general guidelines for formatting documentation
414 using HTML. The description of the various "common pages" gave specific
415 details for formatting specific sections of the documentation, which should
416 override these guidelines.</p>
417
418 <h3><a name="code-format" id="code-format"></a>Code</h3>
419
420 <p>Code within the documentation should be placed within either
421 &lt;code&gt;&lt;/code&gt; or &lt;pre&gt;&lt;/pre&gt; tags. For code that's
422 placed inline with other text you use &lt;code&gt;&lt;/code&gt; tags, while
423 &lt;pre&gt;&lt;/pre&gt; tags are used for code "blocks". If a cascading
424 style sheet is used to specify formatting for these tags, a fixed width
425 sans serif font should be used. This insures that the code is easily
426 distinguishable from the rest of the text. It may also be beneficial to set
427 the style for &lt;pre&gt;&lt;/pre&gt; tags to indent the text, to help
428 separate code blocks from other structural HTML blocks. The <a href=
429 "#boost-style-sheet">Boost Style Sheet</a> specifies formatting for these
430 tags.</p>
431
432 <p><b>Note:</b> "Code" includes variable names, function names, etc.</p>
433
434 <h3><a name="lists" id="lists"></a>Lists</h3>
435
436 <p>Lists should be constructed as unordered (&lt;UL&gt; and &lt;li&gt;
437 tags), ordered (&lt;ol&gt; and &lt;li&gt; tags) or definition (&lt;dl&gt;
438 and &lt;DT&gt; tags) lists in HTML. You use an unordered list when you need
439 a collection of items that don't have any kind of logical ordering, such as
440 a list of data types that are defined by the library and can be used for a
441 template argument. You use an ordered list when the collection of items
442 must be grouped in a logical ordering, such as when enumerating the steps
443 that an action logically performs. You use a definition list when the list
444 consists of not only items that have no logical ordering, but also contains
445 definitions/descriptions/etc. of the items. A good example of this is the
446 function specifications as described in <a href=
447 "structure.html">Documentation Structure</a>.</p>
448
449 <h3><a name="graphics" id="graphics"></a>Graphics</h3>
450
451 <p>Graphics should be used very sparingly, if at all. Graphic images
452 greatly effect the download time for many people, which can discourage
453 users from reading the documentation. If you need graphic images to help
454 illustrate something in your documentation consider supplying only a link
455 to the image within the documentation, instead of embedding it directly in
456 the text. If an image is going to be included in the text of the document
457 you should specify the image's size in the &lt;img&gt; tag, in order to
458 allow the user's browser to optimize the formatting of the text before the
459 image is loaded.</p>
460
461 <h3><a name="non-breaking-spaces" id="non-breaking-spaces"></a>Non-breaking
462 Spaces</h3>
463
464 <p>Non-breaking spaces (&amp;nbsp;) should be avoided in HTML text.
465 Generally there are more appropriate ways to format the document, such as
466 using list constructs or specifying indentation as a style attribute or in
467 cascading style sheets.</p>
468
469 <h3><a name="style-sheets" id="style-sheets"></a>Cascading Style
470 Sheets</h3>
471
472 <p>Cascading style sheets allow you to apply some advanced formatting
473 styles to an HTML document. More importantly, they allow you to change the
474 formatting in a single file and effect all pages using the style sheet.
475 Instead of struggling to produce a specific format in HTML it's often
476 easier and more flexible to specify the formatting in a style sheet.</p>
477
478 <h4><a name="boost-style-sheet" id="boost-style-sheet"></a>Boost Style
479 Sheet</h4>
480
481 <p>The concept of using cascading style sheets to format HTML is such a
482 good idea that it can be beneficial to apply this across the entire Boost
483 site. Of course we can't require this (if Boost were to require such trivia
484 for submissions it's likely that many programmers would be discouraged from
485 contributing). However, a "standard" Boost style sheet
486 (http://www.boost.org/boost.css) is supplied anyway, so that a contributer
487 can quickly and easily produce clear and consistent documentation that
488 reflects a Boost "brand" if they so choose. If, at a later date, it's
489 decided to update the Boost "brand", it may be done in this single file and
490 all documents using the style sheet will automatically be updated.</p>
491
492 <p>The Boost supplied style sheet not only specifies styles for many
493 standard tags, it also specifies several style "classes". A class is
494 specified for a given tag instead of being applied to all instances of a
495 given tag type. Below is a list of the classes specified in the Boost style
496 sheet and a description of when to use them:</p>

512 <p>Instead of hand coding every HTML page, HTML "templates" can be used
513 instead. The list below provides links to templates that may be used when
514 writing documentation for a contribution to Boost. Links provided in these
515 templates assume the files will reside in the "traditional" directory
516 hierarchy of <i>boost/libs/library/doc</i>. They may need correcting if the
517 file will reside in some other location.</p>
518
519 <p><b>Note:</b> Since these "templates" are just HTML pages simply clicking
520 on the links below will load the template in your browser. You will need to
521 use a browser specific method to download the files instead of loading them
522 into the browser (for instance, on most Windows browsers you can right
523 click on the link and select the appropriate command from the context
524 sensitive menu).</p>
