99     <p>This document describes the directives implemented in the reference
100     reStructuredText parser.</p>
101     <p>Directives have the following syntax:</p>
102     <pre class="literal-block">
103     +-------+-------------------------------+
104     | &quot;.. &quot; | directive type &quot;::&quot; directive |
105     +-------+ block |
106     | |
107     +-------------------------------+
108     </pre>
109     <p>Directives begin with an explicit markup start (two periods and a
110     space), followed by the directive type and two colons (collectively,
111     the &quot;directive marker&quot;). The directive block begins immediately after
112     the directive marker, and includes all subsequent indented lines. The
113     directive block is divided into arguments, options (a field list), and
114     content (in that order), any of which may appear. See the <a class="reference external" href="restructuredtext.html#directives">Directives</a>
115     section in the <a class="reference external" href="restructuredtext.html">reStructuredText Markup Specification</a> for syntax
116     details.</p>
117     <p>Descriptions below list &quot;doctree elements&quot; (document tree element
118     names; XML DTD generic identifiers) corresponding to individual
119     directives. For details on the hierarchy of elements, please see <a class="reference external" href="../doctree.html">The
120     Docutils Document Tree</a> and the <a class="reference external" href="../docutils.dtd">Docutils Generic DTD</a> XML document
121     type definition. For directive implementation details, see <a class="reference external" href="../../howto/rst-directives.html">Creating
122     reStructuredText Directives</a>.</p>

144     </table>
145     <p>Admonitions are specially marked &quot;topics&quot; that can appear anywhere an
146     ordinary body element can. They contain arbitrary body elements.
147     Typically, an admonition is rendered as an offset block in a document,
148     sometimes outlined or shaded, with a title matching the admonition
149     type. For example:</p>
150     <pre class="literal-block">
151     .. DANGER::
152     Beware killer rabbits!
153     </pre>
154     <p>This directive might be rendered something like this:</p>
155     <pre class="literal-block">
156     +------------------------+
157     | !DANGER! |
158     | |
159     | Beware killer rabbits! |
160     +------------------------+
161     </pre>
162     <p>The following admonition directives have been implemented:</p>
163     <ul class="simple">
164     <li>attention</li>
165     <li>caution</li>
166     <li>danger</li>
167     <li>error</li>
168     <li>hint</li>
169     <li>important</li>
170     <li>note</li>
171     <li>tip</li>
172     <li>warning</li>
173     </ul>
174     <p>Any text immediately following the directive indicator (on the same
175     line and/or indented on following lines) is interpreted as a directive
176     block and is parsed for normal body elements. For example, the
177     following &quot;note&quot; admonition directive contains one paragraph and a
178     bullet list consisting of two list items:</p>
179     <pre class="literal-block">
180     .. note:: This is a note admonition.
181     This is the second line of the first paragraph.
183     - The note contains all indented body elements
184     following.
185     - It includes this bullet list.

207     author desires.</p>
208     <p>The author-supplied title is also used as a &quot;classes&quot; attribute value
209     after being converted into a valid identifier form (down-cased;
210     non-alphanumeric characters converted to single hyphens; &quot;admonition-&quot;
211     prefixed). For example, this admonition:</p>

255     <p>An &quot;image&quot; is a simple picture:</p>
256     <pre class="literal-block">
257     .. image:: picture.png
258     </pre>
259     <p>The URI for the image source file is specified in the directive
260     argument. As with hyperlink targets, the image URI may begin on the
261     same line as the explicit markup start and target name, or it may
262     begin in an indented text block immediately following, with no
263     intervening blank lines. If there are multiple lines in the link
264     block, they are stripped of leading and trailing whitespace and joined
265     together.</p>
266     <p>Optionally, the image link block may contain a flat field list, the
267     <span class="target" id="image-options">image options</span>. For example:</p>
268     <pre class="literal-block">

283     <dd>The desired height of the image.
284     Used to reserve space or scale the image vertically. When the &quot;scale&quot;
285     option is also specified, they are combined. For example, a height of
286     200px and a scale of 50 is equivalent to a height of 100px with no scale.</dd>
287     <dt><tt class="docutils literal">width</tt> <span class="classifier-delimiter">:</span> <span class="classifier"><a class="reference external" href="restructuredtext.html#length-units">length</a> or <a class="reference external" href="restructuredtext.html#percentage-units">percentage</a> of the current line width</span></dt>
288     <dd>The width of the image.
289     Used to reserve space or scale the image horizontally. As with &quot;height&quot;
290     above, when the &quot;scale&quot; option is also specified, they are combined.</dd>

301     control an image's vertical alignment (relative to the text
302     baseline); they are only useful for inline images (substitutions).
303     The values &quot;left&quot;, &quot;center&quot;, and &quot;right&quot; control an image's
304     horizontal alignment, allowing the image to float and have the
305     text flow around it. The specific behavior depends upon the

525     block.) Line blocks are useful for address blocks and verse (poetry,

565     <p>Unlike an ordinary literal block, the &quot;parsed-literal&quot; directive
566     constructs a literal block where the text is parsed for inline markup.
567     It is equivalent to a <a class="reference internal" href="#line-block">line block</a> with different rendering:
568     typically in a typewriter/monospaced typeface, like an ordinary
569     literal block. Parsed literal blocks are useful for adding hyperlinks
570     to code examples.</p>
571     <p>However, care must be taken with the text, because inline markup is
572     recognized and there is no protection from parsing. Backslash-escapes
573     may be necessary to prevent unintended parsing. And because the
574     markup characters are removed by the parser, care must also be taken
575     with vertical alignment. Parsed &quot;ASCII art&quot; is tricky, and extra
576     whitespace may be necessary.</p>
577     <p>For example, all the element names in this content model are links:</p>
578     <pre class="literal-block">

734     is a single logical paragraph containing multiple physical body
735     elements such as simple paragraphs, literal blocks, tables, lists,

797     with the optional &quot;<a class="reference internal" href="#classes">classes</a>&quot; attribute argument(s), this is an

1110     1, subsection 2, subsubsection 3 would have &quot;1.2.3&quot; prefixed.</p>
1111     <p>The &quot;sectnum&quot; directive does its work in two passes: the initial parse
1112     and a transform. During the initial parse, a &quot;pending&quot; element is
1113     generated which acts as a placeholder, storing any options internally.
1114     At a later stage in the processing, the &quot;pending&quot; element triggers a
1115     transform, which adds section numbers to titles. Section numbers are
1116     enclosed in a &quot;generated&quot; element, and titles have their &quot;auto&quot;
1117     attribute set to &quot;1&quot;.</p>
1118     <p>The following options are recognized:</p>
1119     <dl class="docutils">
1120     <dt><tt class="docutils literal">depth</tt> <span class="classifier-delimiter">:</span> <span class="classifier">integer</span></dt>
1121     <dd>The number of section levels that are numbered by this directive.
1122     The default is unlimited depth.</dd>
1123     <dt><tt class="docutils literal">prefix</tt> <span class="classifier-delimiter">:</span> <span class="classifier">string</span></dt>
1124     <dd>An arbitrary string that is prefixed to the automatically
1125     generated section numbers. It may be something like &quot;3.2.&quot;, which
1126     will produce &quot;3.2.1&quot;, &quot;3.2.2&quot;, &quot;;, and so on. Note that
1127     any separating punctuation (in the example, a period, &quot;.&quot;) must be
1128     explicitly provided. The default is no prefix.</dd>
1129     <dt><tt class="docutils literal">suffix</tt> <span class="classifier-delimiter">:</span> <span class="classifier">string</span></dt>
1130     <dd>An arbitrary string that is appended to the automatically

1132     <dt><tt class="docutils literal">start</tt> <span class="classifier-delimiter">:</span> <span class="classifier">integer</span></dt>
1133     <dd>The value that will be used for the first section number.
1134     Combined with <tt class="docutils literal">prefix</tt>, this may be used to force the right
1135     numbering for a document split over several source files. The
1136     default is 1.</dd>

1157     <p>(New in Docutils 0.3.8)</p>
1158     <p>The &quot;header&quot; and &quot;footer&quot; directives create document decorations,
1159     useful for page navigation, notes, time/datestamp, etc. For example:</p>
1160     <pre class="literal-block">
1161     .. header:: This space for rent.
1162     </pre>
1163     <p>This will add a paragraph to the document header, which will appear at
1164     the top of the generated web page or at the top of every printed page.</p>
1165     <p>These directives may be used multiple times, cumulatively. There is
1166     currently support for only one header and footer.</p>
1167     <div class="note">
1168     <p class="first admonition-title">Note</p>
1169     <p>While it is possible to use the &quot;header&quot; and &quot;footer&quot; directives to
1170     create navigational elements for web pages, you should be aware
1171     that Docutils is meant to be used for <em>document</em> processing, and
1172     that a navigation bar is not typically part of a document.</p>
1173     <p class="last">Thus, you may soon find Docutils' abilities to be insufficient for
1174     these purposes. At that time, you should consider using a
1175     templating system (like <a class="reference external" href="">ht2html</a>) rather than the &quot;header&quot; and
1176     &quot;footer&quot; directives.</p>
1177     </div>
1178     <p>In addition to the use of these directives to populate header and
1179     footer content, content may also be added automatically by the
1180     processing system. For example, if certain runtime settings are
1181     enabled, the document footer is populated with processing information
1182     such as a datestamp, a link to <a class="reference external" href="">the Docutils website</a>, etc.</p>

1280     <p>The &quot;meta&quot; directive is used to specify HTML metadata stored in HTML
1281     META tags. &quot;Metadata&quot; is data about data, in this case data about web
1282     pages. Metadata is used to describe and classify web pages in the
1283     World Wide Web, in a form that is easy for search engines to extract
1284     and collate.</p>
1285     <p>Within the directive block, a flat field list provides the syntax for
1286     metadata. The field name becomes the contents of the &quot;name&quot; attribute
1287     of the META tag, and the field body (interpreted as a single string
1288     without inline markup) becomes the contents of the &quot;content&quot;
1289     attribute. For example:</p>
1290     <pre class="literal-block">
1291     .. meta::
1292     :description: The reStructuredText plaintext markup language
1293     :keywords: plaintext, markup language
1294     </pre>
1295     <p>This would be converted to the following HTML:</p>
1296     <pre class="literal-block">
1297     &lt;meta name=&quot;description&quot;
1298     content=&quot;The reStructuredText plaintext markup language&quot;&gt;
1299     &lt;meta name=&quot;keywords&quot; content=&quot;plaintext, markup language&quot;&gt;
1300     </pre>
1301     <p>Support for other META attributes (&quot;http-equiv&quot;, &quot;scheme&quot;, &quot;lang&quot;,
1302     &quot;dir&quot;) are provided through field arguments, which must be of the form
1303     &quot;attr=value&quot;:</p>
1304     <pre class="literal-block">
1305     .. meta::
1306     :description lang=en: An amusing story
1307     :description lang=fr: Une histoire amusante
1308     </pre>
1309     <p>And their HTML equivalents:</p>
1310     <pre class="literal-block">
1311     &lt;meta name=&quot;description&quot; lang=&quot;en&quot; content=&quot;An amusing story&quot;&gt;
1312     &lt;meta name=&quot;description&quot; lang=&quot;fr&quot; content=&quot;Une histoire amusante&quot;&gt;
1313     </pre>
1314     <p>Some META tags use an &quot;http-equiv&quot; attribute instead of the &quot;name&quot;
1315     attribute. To specify &quot;http-equiv&quot; META tags, simply omit the name:</p>
1316     <pre class="literal-block">
1317     .. meta::

1776     <p>The &quot;role&quot; directive dynamically creates a custom interpreted text

1779     <pre class="literal-block">
1780     .. role:: custom
1781     </pre>

1858     <p>The &quot;default-role&quot; directive sets the default interpreted text role,
1859     the role that is used for interpreted text without an explicit role.
1860     For example, after setting the default role like this:</p>
1861     <pre class="literal-block">
1862     .. default-role:: subscript
1863     </pre>
1864     <p>any subsequent use of implicit-role interpreted text in the document
1865     will use the &quot;subscript&quot; role:</p>
1866     <pre class="literal-block">
1867     An example of a `default` role.
1868     </pre>
1869     <p>This will be parsed into the following document tree fragment:</p>
1870     <pre class="literal-block">
1871     &lt;paragraph&gt;
1872     An example of a
1873     &lt;subscript&gt;
1874     default
1875     role.
1876     </pre>
1877     <p>Custom roles may be used (see the &quot;<a class="reference internal" href="#role">role</a>&quot; directive above), but it
1878     must have been declared in a document before it can be set as the
1879     default role. See the <a class="reference external" href="roles.html">reStructuredText Interpreted Text Roles</a>
1880     document for details of built-in roles.</p>
1881     <p>The directive may be used without an argument to restore the initial
1882     default interpreted text role, which is application-dependent. The
1883     initial default interpreted text role of the standard reStructuredText
1884     parser is &quot;title-reference&quot;.</p>

1904     <p>The &quot;title&quot; directive specifies the document title as metadata, which
1905     does not become part of the document body. It overrides a
1906     document-supplied title. For example, in HTML output the metadata
1907     document title appears in the title bar of the browser window.</p>
