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

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>

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>

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>
497
498  <dl>
499    <dt><b>index</b> Used for &lt;dl&gt; tags when writing index lists.</dt>
500
501    <dt><b>page-index</b> Used for &lt;dl&gt; tags when writing page index
502    lists.</dt>
503
504    <dt><b>Footnote</b> Used when writing Footnote numbers.</dt>
505
506    <dt><b>function-semantics</b> Used for &lt;dl&gt; tags when writing
507    function semantic lists.</dt>
508  </dl>
509
510  <h2><a name="templates" id="templates"></a>Templates</h2>
511
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>
