<h1>Execute Python Code<a class="headerlink" href="#execute-python-code" title="Permalink to this headline">¶</a></h1>
|
||||
<p>The <code class="docutils literal notranslate"><span class="pre">@py</span></code> command supplied with the default command set of Evennia allows you to execute Python
|
||||
commands directly from inside the game. An alias to <code class="docutils literal notranslate"><span class="pre">@py</span></code> is simply “<code class="docutils literal notranslate"><span class="pre">!</span></code>”. <em>Access to the <code class="docutils literal notranslate"><span class="pre">@py</span></code>
|
||||
command should be severely restricted</em>. This is no joke - being able to execute arbitrary Python
|
||||
code on the server is not something you should entrust to just anybody.</p>
|
||||

<section id="available-variables">
|

<h2>Available variables<a class="headerlink" href="#available-variables" title="Permalink to this headline">¶</a></h2>
|
||||
<p>A few local variables are made available when running <code class="docutils literal notranslate"><span class="pre">@py</span></code>. These offer entry into the running
|
||||
system.</p>
|
||||
<ul class="simple">
|
||||
<li><p><strong>self</strong> / <strong>me</strong> - the calling object (i.e. you)</p></li>
|
||||
<li><p><strong>here</strong> - the current caller’s location</p></li>
|
||||
<li><p><strong>obj</strong> - a dummy <a class="reference internal" href="Objects.html"><span class="doc">Object</span></a> instance</p></li>
|
||||
<li><p><strong>evennia</strong> - Evennia’s <a class="reference internal" href="Evennia-API.html"><span class="doc">flat API</span></a> - through this you can access all of Evennia.</p></li>
|
||||
</ul>
|
||||
<p>For accessing other objects in the same room you need to use <code class="docutils literal notranslate"><span class="pre">self.search(name)</span></code>. For objects in
|
||||
other locations, use one of the <code class="docutils literal notranslate"><span class="pre">evennia.search_*</span></code> methods. See [below](./Execute-Python-Code#finding-
|
||||
objects).</p>

<section id="returning-output">
|

<h2>Returning output<a class="headerlink" href="#returning-output" title="Permalink to this headline">¶</a></h2>
|
||||
<p>This is an example where we import and test one of Evennia’s utilities found in
|
||||
<code class="docutils literal notranslate"><span class="pre">src/utils/utils.py</span></code>, but also accessible through <code class="docutils literal notranslate"><span class="pre">ev.utils</span></code>:</p>
|
||||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="nd">@py</span> <span class="kn">from</span> <span class="nn">ev</span> <span class="kn">import</span> <span class="n">utils</span><span class="p">;</span> <span class="n">utils</span><span class="o">.</span><span class="n">time_format</span><span class="p">(</span><span class="mi">33333</span><span class="p">)</span>

<span class="o"><<<</span> <span class="n">Done</span><span class="o">.</span>
|
||||
</pre></div>
|
||||
</div>
|
||||
<p>Note that we didn’t get any return value, all we where told is that the code finished executing
|
||||
without error. This is often the case in more complex pieces of code which has no single obvious
|
||||
return value. To see the output from the <code class="docutils literal notranslate"><span class="pre">time_format()</span></code> function we need to tell the system to
|
||||
echo it to us explicitly with <code class="docutils literal notranslate"><span class="pre">self.msg()</span></code>.</p>
|
||||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="nd">@py</span> <span class="kn">from</span> <span class="nn">ev</span> <span class="kn">import</span> <span class="n">utils</span><span class="p">;</span> <span class="bp">self</span><span class="o">.</span><span class="n">msg</span><span class="p">(</span><span class="nb">str</span><span class="p">(</span><span class="n">utils</span><span class="o">.</span><span class="n">time_format</span><span class="p">(</span><span class="mi">33333</span><span class="p">)))</span>

<blockquote>
|
||||
<div><p>Warning: When using the <code class="docutils literal notranslate"><span class="pre">msg</span></code> function wrap our argument in <code class="docutils literal notranslate"><span class="pre">str()</span></code> to convert it into a string
|
||||
above. This is not strictly necessary for most types of data (Evennia will usually convert to a
|
||||
string behind the scenes for you). But for <em>lists</em> and <em>tuples</em> you will be confused by the output
|
||||
if you don’t wrap them in <code class="docutils literal notranslate"><span class="pre">str()</span></code>: only the first item of the iterable will be returned. This is
|
||||
because doing <code class="docutils literal notranslate"><span class="pre">msg(text)</span></code> is actually just a convenience shortcut; the full argument that <code class="docutils literal notranslate"><span class="pre">msg</span></code>
|
||||
accepts is something called an <em>outputfunc</em> on the form <code class="docutils literal notranslate"><span class="pre">(cmdname,</span> <span class="pre">(args),</span> <span class="pre">{kwargs})</span></code> (see <a class="reference internal" href="Messagepath.html"><span class="doc">the
|
||||
message path</span></a> for more info). Sending a list/tuple confuses Evennia to think you are
|
||||
sending such a structure. Converting it to a string however makes it clear it should just be
|
||||
displayed as-is.</p>
|
||||
</div></blockquote>
|
||||
<p>If you were to use Python’s standard <code class="docutils literal notranslate"><span class="pre">print</span></code>, you will see the result in your current <code class="docutils literal notranslate"><span class="pre">stdout</span></code> (your
|
||||
terminal by default, otherwise your log file).</p>

<h2>Finding objects<a class="headerlink" href="#finding-objects" title="Permalink to this headline">¶</a></h2>
|
||||
<p>A common use for <code class="docutils literal notranslate"><span class="pre">@py</span></code> is to explore objects in the database, for debugging and performing specific
|
||||
operations that are not covered by a particular command.</p>
|
||||
<p>Locating an object is best done using <code class="docutils literal notranslate"><span class="pre">self.search()</span></code>:</p>

|

</div>
|
||||
<p><code class="docutils literal notranslate"><span class="pre">self.search()</span></code> is by far the most used case, but you can also search other database tables for
|
||||
other Evennia entities like scripts or configuration entities. To do this you can use the generic
|
||||
search entries found in <code class="docutils literal notranslate"><span class="pre">ev.search_*</span></code>.</p>

|

</div>
|
||||
<p>(Note that since this becomes a simple statement, we don’t have to wrap it in <code class="docutils literal notranslate"><span class="pre">self.msg()</span></code> to get
|
||||
the output). You can also use the database model managers directly (accessible through the <code class="docutils literal notranslate"><span class="pre">objects</span></code>
|
||||
properties of database models or as <code class="docutils literal notranslate"><span class="pre">evennia.managers.*</span></code>). This is a bit more flexible since it
|

gives you access to the full range of database search methods defined in each manager.</p>

|
||||
<p><code class="docutils literal notranslate"><span class="pre">@py</span></code> has the advantage of operating inside a running server (sharing the same process), where you
|
||||
can test things in real time. Much of this <em>can</em> be done from the outside too though.</p>
|
||||
<p>In a terminal, cd to the top of your game directory (this bit is important since we need access to
|
||||
your config file) and run</p>

</div>
|

<p>Your default Python interpreter will start up, configured to be able to work with and import all
|
||||
modules of your Evennia installation. From here you can explore the database and test-run individual
|
||||
modules as desired.</p>
|
||||
<p>It’s recommended that you get a more fully featured Python interpreter like
|
||||
<a class="reference external" href="http://ipython.scipy.org/moin/">iPython</a>. If you use a virtual environment, you can just get it
|
||||
with <code class="docutils literal notranslate"><span class="pre">pip</span> <span class="pre">install</span> <span class="pre">ipython</span></code>. IPython allows you to better work over several lines, and also has a lot
|
||||
of other editing features, such as tab-completion and <code class="docutils literal notranslate"><span class="pre">__doc__</span></code>-string reading.</p>
