<div class="section" id="prerequisites">
<h2>Prerequisites<a class="headerlink" href="#prerequisites" title="Permalink to this headline">¶</a></h2>
<p>You’ll need to have <a class="reference external" href="https://www.python.org/downloads/release/python-382/">Python 3.8</a> and <a class="reference external" href="https://github.com/python-poetry/poetry">poetry</a>
to develop Royalnet Packs.</p>
</div>
<div class="section" id="creating-the-repository">
<h2>Creating the repository<a class="headerlink" href="#creating-the-repository" title="Permalink to this headline">¶</a></h2>
<p>To create a new pack, create a new repository based on the <a class="reference external" href="https://github.com/Steffo99/royalnet-pack-template">Royalnet Pack template</a>
and clone it to your workspace.</p>
<p>After cloning the template, run <code class="docutils literal notranslate"><span class="pre">poetry</span> <span class="pre">install</span></code> to install the dependencies for the pack, creating the <code class="docutils literal notranslate"><span class="pre">poetry.lock</span></code> file.</p>
<div class="section" id="pyproject-toml">
<h3>pyproject.toml<a class="headerlink" href="#pyproject-toml" title="Permalink to this headline">¶</a></h3>
<p>The <code class="docutils literal notranslate"><span class="pre">pyproject.toml</span></code> file contains information about your Python project that will be read by <code class="docutils literal notranslate"><span class="pre">poetry</span></code> while building
the pack and publishing it to PyPI.</p>
<p>Choose a name for your Pack and set it in the <code class="docutils literal notranslate"><span class="pre">tool.property.name</span></code> field:</p>

<p>The <code class="docutils literal notranslate"><span class="pre">examplepack</span></code> folder contains the source code of your pack, and should be renamed to the name you set in the <code class="docutils literal notranslate"><span class="pre">pyproject.toml</span></code> file.</p>
<p>It should contain a <code class="docutils literal notranslate"><span class="pre">version.py</span></code> file and six folders:</p>

<p>The <code class="docutils literal notranslate"><span class="pre">version.py</span></code> file contains the version number of your pack.</p>
<p>If you changed the <code class="docutils literal notranslate"><span class="pre">version</span></code> field in the <code class="docutils literal notranslate"><span class="pre">pyproject.toml</span></code> file, change the value of <code class="docutils literal notranslate"><span class="pre">semantic</span></code> in <code class="docutils literal notranslate"><span class="pre">version.py</span></code> to the same value.</p>

<div class="section" id="the-commands-folder">
<h3>The commands folder<a class="headerlink" href="#the-commands-folder" title="Permalink to this headline">¶</a></h3>
<p>The commands folder should contain all commands that your Pack will add to the Royalnet instances it is installed in.</p>
<p>To learn how to create a new <code class="xref py py-class docutils literal notranslate"><span class="pre">Command</span></code>, read the <a class="reference internal" href="command.html"><span class="doc">Creating a new Command</span></a> page.</p>
</div>
<div class="section" id="the-events-folder">
<h3>The events folder<a class="headerlink" href="#the-events-folder" title="Permalink to this headline">¶</a></h3>
<p>The events folder should contain all events (remote procedure calls) that your Pack will add to the Royalnet instances it is installed in.</p>
<p>To learn how to create a new <code class="xref py py-class docutils literal notranslate"><span class="pre">Event</span></code>, read the <a class="reference internal" href="event.html"><span class="doc">Using Events</span></a> page.</p>

<div class="section" id="the-tables-folder">
<h3>The tables folder<a class="headerlink" href="#the-tables-folder" title="Permalink to this headline">¶</a></h3>
<p>The tables folder should contain all Alchemy tables (SQLAlchemy-compatible SQL tables) that your Pack will add to the Royalnet instances it is installed in.</p>
<p>To learn how to create a new table, read the <a class="reference internal" href="table.html"><span class="doc">Using Tables and databases</span></a> page.</p>
</div>
<div class="section" id="the-utils-folder">
<h3>The utils folder<a class="headerlink" href="#the-utils-folder" title="Permalink to this headline">¶</a></h3>
<p>The utils folder should contain the utility functions and classes that your Pack uses.</p>
<p>Its contents are imported <strong>before</strong> the commands, events and stars but <strong>after</strong> the tables, so <strong>you can’t import them</strong> in the files contained in the <code class="docutils literal notranslate"><span class="pre">tables</span></code> folder, or you will create a <a class="reference external" href="https://stackabuse.com/python-circular-imports/">circular import</a>!</p>
<p>Files in this folder are <strong>forbidden from importing modules</strong> from the <code class="docutils literal notranslate"><span class="pre">commands</span></code>, <code class="docutils literal notranslate"><span class="pre">events</span></code> and <code class="docutils literal notranslate"><span class="pre">stars</span></code> folders, as that will create a circular import too.</p>
</div>
<div class="section" id="the-types-folder">
<h3>The types folder<a class="headerlink" href="#the-types-folder" title="Permalink to this headline">¶</a></h3>
<p>The types folder should contain the enums and custom types that are used in your tables.</p>
<p>Please note that the contents of this folder are imported <strong>before</strong> everything else in the pack.</p>
<p>Its contents <strong>can be imported anywhere</strong> in the Pack, including the <code class="docutils literal notranslate"><span class="pre">tables</span></code> folder, without creating a circular import.</p>
<p>However, its files are <strong>forbidden from importing anything else</strong> from the rest of the pack!</p>

<div class="section" id="adding-new-dependencies-to-the-pack">
<h2>Adding new dependencies to the Pack<a class="headerlink" href="#adding-new-dependencies-to-the-pack" title="Permalink to this headline">¶</a></h2>
<p>As the Pack is actually a Python package, you can use <code class="docutils literal notranslate"><span class="pre">poetry</span></code> (or <code class="docutils literal notranslate"><span class="pre">pip</span></code>) to add new dependencies!</p>
<p>Use <code class="docutils literal notranslate"><span class="pre">poetry</span> <span class="pre">add</span> <span class="pre">packagename</span></code> to add and install a new dependency from the PyPI.</p>
</div>
<div class="section" id="publishing-the-pack">
<h2>Publishing the pack<a class="headerlink" href="#publishing-the-pack" title="Permalink to this headline">¶</a></h2>
<p>To publish your Pack on the PyPI, run <code class="docutils literal notranslate"><span class="pre">poetry</span> <span class="pre">build</span></code>, then <code class="docutils literal notranslate"><span class="pre">poetry</span> <span class="pre">publish</span></code>.</p>
