| <p>The documentation build process uses <a class="reference external" href="http://www.doxygen.nl/">Doxygen</a> and |
| <a class="reference external" href="http://www.sphinx-doc.org/">Sphinx</a> along with a few extensions.</p> |
| <p>If you’re using Conda, the required software can be installed in a single line:</p> |
| <div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>conda<span class="w"> </span>install<span class="w"> </span>-c<span class="w"> </span>conda-forge<span class="w"> </span>--file<span class="o">=</span>arrow/ci/conda_env_sphinx.txt |
| </pre></div> |
| </div> |
| <p>Otherwise, you’ll first need to install <a class="reference external" href="http://www.doxygen.nl/">Doxygen</a> |
| yourself (for example from your distribution’s official repositories, if |
| using Linux). Then you can install the Python-based requirements with the |
| following command:</p> |

| <div class="admonition note"> |
| <p class="admonition-title">Note</p> |
| <p>If you are working on the Python bindings documentation then |
| this step requires that <code class="docutils literal notranslate"><span class="pre">pyarrow</span></code> library is installed |
| in your python environment. One way to accomplish |
| this is to follow the build instructions at <a class="reference internal" href="python.html#python-development"><span class="std std-ref">Python Development</span></a> |
| and then run <code class="docutils literal notranslate"><span class="pre">python</span> <span class="pre">setup.py</span> <span class="pre">install</span></code> in arrow/python |
| (it is best to do this in a dedicated conda/virtual environment).</p> |
| <p>You can still build the documentation without <code class="docutils literal notranslate"><span class="pre">pyarrow</span></code> |
| library installed but note that Python part of the documentation |
| will be missing from the <code class="docutils literal notranslate"><span class="pre">_build/html</span></code> file structure and the |
| links to the Python documentation will get broken.</p> |

| <p>Note that building the documentation may fail if your build of pyarrow is |
| not sufficiently comprehensive. Portions of the Python API documentation |
| will also not build without CUDA support having been built.</p> |
| </div> |
| <p>After these steps are completed, the documentation is rendered in HTML |
| format in <code class="docutils literal notranslate"><span class="pre">arrow/docs/_build/html</span></code>. In particular, you can point your browser |

| <h3>Building a single directory for dev purposes without all the pre-requisites<a class="headerlink" href="#building-a-single-directory-for-dev-purposes-without-all-the-pre-requisites" title="Permalink to this heading">#</a></h3> |
| <p>You can build documentation in a single directory without needing to install |
| all of the pre-requisites by installing sphinx, setting up a temporary |
| index in the directory you want to build and then building that directory.</p> |
| <p>The example below shows how to do this in the <code class="docutils literal notranslate"><span class="pre">arrow/docs/source/developers</span></code> directory.</p> |
| <p>Install <code class="docutils literal notranslate"><span class="pre">sphinx</span></code>:</p> |
| <div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>pip<span class="w"> </span>install<span class="w"> </span>sphinx |
| </pre></div> |
| </div> |
| <p>Navigate to the <code class="docutils literal notranslate"><span class="pre">arrow/docs</span></code> directory:</p> |
| <div class="highlight-shell notranslate"><div class="highlight"><pre><span></span><span class="nb">cd</span><span class="w"> </span>arrow/docs |
| </pre></div> |
| </div> |
| <p>Create an temporary index file <code class="docutils literal notranslate"><span class="pre">temp_index.rst</span></code> file in the target directory:</p> |
| <div class="highlight-shell notranslate"><div class="highlight"><pre><span></span><span class="nb">echo</span><span class="w"> </span><span class="s1">$'.. toctree::\n\t:glob:\n\n\t*'</span><span class="w"> </span>><span class="w"> </span>./source/developers/temp_index.rst |
| </pre></div> |
| </div> |
| <p>Build the docs in the target directory:</p> |
| <div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>sphinx-build<span class="w"> </span>./source/developers<span class="w"> </span>./source/developers/_build<span class="w"> </span>-c<span class="w"> </span>./source<span class="w"> </span>-D<span class="w"> </span><span class="nv">master_doc</span><span class="o">=</span>temp_index |
| </pre></div> |
| </div> |
| <p>This builds everything in the target directory to a folder inside of it |
| called <code class="docutils literal notranslate"><span class="pre">_build</span></code> using the config file in the <cite>source</cite> directory.</p> |
| <p>Once you have verified the HTML documents, you can remove temporary index file:</p> |
| <div class="highlight-shell notranslate"><div class="highlight"><pre><span></span>rm<span class="w"> </span>./source/developers/temp_index.rst |
