<h1>Sphinx Quickstart Template<a class="headerlink" href="#sphinx-quickstart-template" title="Permalink to this headline">¶</a></h1>
<div class="section" id="introduction-and-quickstart">
<h2>Introduction and Quickstart<a class="headerlink" href="#introduction-and-quickstart" title="Permalink to this headline">¶</a></h2>
<p>This document is meant to get you writing documentation as fast as possible
even if you have no previous experience with Sphinx. The goal is to take
someone in the state of “I want to write documentation and get it added to
LLVM’s docs” and turn that into useful documentation mailed to llvm-commits
with as little nonsense as possible.</p>
<p>You can find this document in <code class="docutils literal notranslate"><span class="pre">docs/SphinxQuickstartTemplate.rst</span></code>. You
should copy it, open the new file in your text editor, write your docs, and
then send the new document to llvm-commits for review.</p>
<p>Focus on <em>content</em>. It is easy to fix the Sphinx (reStructuredText) syntax
later if necessary, although reStructuredText tries to imitate common
plain-text conventions so it should be quite natural. A basic knowledge of
reStructuredText syntax is useful when writing the document, so the last
~half of this document (starting with <a class="reference internal" href="#example-section">Example Section</a>) gives examples
which should cover 99% of use cases.</p>
<p>Let me say that again: focus on <em>content</em>. But if you really need to verify
Sphinx’s output, see <code class="docutils literal notranslate"><span class="pre">docs/README.txt</span></code> for information.</p>
<p>Once you have finished with the content, please send the <code class="docutils literal notranslate"><span class="pre">.rst</span></code> file to
llvm-commits for review.</p>
</div>
<div class="section" id="guidelines">
<h2>Guidelines<a class="headerlink" href="#guidelines" title="Permalink to this headline">¶</a></h2>
<p>Try to answer the following questions in your first section:</p>
<ol class="arabic simple">
<li>Why would I want to read this document?</li>
<li>What should I know to be able to follow along with this document?</li>
<li>What will I have learned by the end of this document?</li>
</ol>
<p>Common names for the first section are <code class="docutils literal notranslate"><span class="pre">Introduction</span></code>, <code class="docutils literal notranslate"><span class="pre">Overview</span></code>, or
<code class="docutils literal notranslate"><span class="pre">Background</span></code>.</p>
<p>If possible, make your document a “how to”. Give it a name <code class="docutils literal notranslate"><span class="pre">HowTo*.rst</span></code>
like the other “how to” documents. This format is usually the easiest
for another person to understand and also the most useful.</p>
<p>You generally should not be writing documentation other than a “how to”
unless there is already a “how to” about your topic. The reason for this
is that without a “how to” document to read first, it is difficult for a
person to understand a more advanced document.</p>
<p>Focus on content (yes, I had to say it again).</p>
<p>The rest of this document shows example reStructuredText markup constructs
that are meant to be read by you in your text editor after you have copied
this file into a new file for the documentation you are about to write.</p>
</div>
<div class="section" id="example-section">
<h2>Example Section<a class="headerlink" href="#example-section" title="Permalink to this headline">¶</a></h2>
<p>Your text can be <em>emphasized</em>, <strong>bold</strong>, or <code class="docutils literal notranslate"><span class="pre">monospace</span></code>.</p>
<p>Use blank lines to separate paragraphs.</p>
<p>Headings (like <code class="docutils literal notranslate"><span class="pre">Example</span> <span class="pre">Section</span></code> just above) give your document its
structure. Use the same kind of adornments (e.g. <code class="docutils literal notranslate"><span class="pre">======</span></code> vs. <code class="docutils literal notranslate"><span class="pre">------</span></code>)
as are used in this document. The adornment must be the same length as the
text above it. For Vim users, variations of <code class="docutils literal notranslate"><span class="pre">yypVr=</span></code> might be handy.</p>
<div class="section" id="example-subsection">
<h3>Example Subsection<a class="headerlink" href="#example-subsection" title="Permalink to this headline">¶</a></h3>
<p>Make a link <a class="reference external" href="http://llvm.org/">like this</a>. There is also a more
sophisticated syntax which <a class="reference external" href="http://en.wikipedia.org/wiki/LLVM">can be more readable</a> for longer links since
it disrupts the flow less. You can put the <code class="docutils literal notranslate"><span class="pre">..</span> <span class="pre">_`link</span> <span class="pre">text`:</span> <span class="pre"><URL></span></code> block
pretty much anywhere later in the document.</p>
<p>Lists can be made like this:</p>
<ol class="arabic simple">
<li>A list starting with <code class="docutils literal notranslate"><span class="pre">#.</span></code> will be automatically numbered.</li>
<li>This is a second list element.<ol class="arabic">
<li>Use indentation to create nested lists.</li>
</ol>
</li>
</ol>
<p>You can also use unordered lists.</p>
<ul class="simple">
<li>Stuff.<ul>
<li>Deeper stuff.</li>
</ul>
</li>
<li>More stuff.</li>
</ul>
<div class="section" id="example-subsubsection">
<h4>Example Subsubsection<a class="headerlink" href="#example-subsubsection" title="Permalink to this headline">¶</a></h4>
<p>You can make blocks of code like this:</p>
<div class="highlight-c++ notranslate"><div class="highlight"><pre><span></span><span class="kt">int</span> <span class="nf">main</span><span class="p">()</span> <span class="p">{</span>
<span class="k">return</span> <span class="mi">0</span><span class="p">;</span>
<span class="p">}</span>
</pre></div>
</div>
<p>For a shell session, use a <code class="docutils literal notranslate"><span class="pre">console</span></code> code block (some existing docs use
<code class="docutils literal notranslate"><span class="pre">bash</span></code>):</p>
<div class="highlight-console notranslate"><div class="highlight"><pre><span></span><span class="gp">$</span> <span class="nb">echo</span> <span class="s2">"Goodbye cruel world!"</span>
<span class="gp">$</span> rm -rf /
</pre></div>
</div>
<p>If you need to show LLVM IR use the <code class="docutils literal notranslate"><span class="pre">llvm</span></code> code block.</p>
<div class="highlight-llvm notranslate"><div class="highlight"><pre><span></span><span class="k">define</span> <span class="k">i32</span> <span class="vg">@test1</span><span class="p">()</span> <span class="p">{</span>
<span class="nl">entry:</span>
<span class="k">ret</span> <span class="k">i32</span> <span class="m">0</span>
<span class="p">}</span>
</pre></div>
</div>
<p>Some other common code blocks you might need are <code class="docutils literal notranslate"><span class="pre">c</span></code>, <code class="docutils literal notranslate"><span class="pre">objc</span></code>, <code class="docutils literal notranslate"><span class="pre">make</span></code>,
and <code class="docutils literal notranslate"><span class="pre">cmake</span></code>. If you need something beyond that, you can look at the <a class="reference external" href="http://pygments.org/docs/lexers/">full
list</a> of supported code blocks.</p>
<p>However, don’t waste time fiddling with syntax highlighting when you could
be adding meaningful content. When in doubt, show preformatted text
without any syntax highlighting like this:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span> <span class="o">.</span>
<span class="o">+</span><span class="p">:</span><span class="o">.</span>
<span class="o">..</span><span class="p">::</span> <span class="p">::</span>
<span class="o">.++</span><span class="p">:</span><span class="o">+</span><span class="p">::</span> <span class="p">::</span><span class="o">+</span><span class="p">:</span><span class="o">.</span><span class="p">:</span><span class="o">.</span>
<span class="o">.</span><span class="p">:</span><span class="o">+</span> <span class="p">:</span>
<span class="p">::</span><span class="o">.</span><span class="p">::</span><span class="o">..</span><span class="p">::</span> <span class="o">.+.</span>
<span class="o">..</span><span class="p">:</span><span class="o">+</span> <span class="p">::</span> <span class="p">:</span>
<span class="o">......+</span><span class="p">:</span><span class="o">.</span> <span class="o">..</span>
<span class="p">:</span><span class="o">++.</span> <span class="o">..</span> <span class="p">:</span>
<span class="o">.+</span><span class="p">:::</span><span class="o">+</span><span class="p">::</span> <span class="p">:</span>
<span class="o">..</span> <span class="o">.</span> <span class="o">.+</span> <span class="p">::</span>
<span class="o">+.</span><span class="p">:</span> <span class="o">.</span><span class="p">::</span><span class="o">+.</span>
<span class="o">...+.</span> <span class="o">.</span><span class="p">:</span> <span class="o">.</span>
<span class="o">.++</span><span class="p">:</span><span class="o">..</span>
<span class="o">...</span>
</pre></div>
