<p>To run this code, store it in a file (<em>e.g.</em>, test.alc), and execute the following commands:</p>
<div class="highlight-default"><div class="highlight"><pre><span class="n">python</span> <span class="n">scripts</span><span class="o">/</span><span class="n">run_local_modelverse</span><span class="o">.</span><span class="n">py</span> <span class="mi">8001</span> <span class="o">&amp;</span>
<span class="n">python</span> <span class="n">scripts</span><span class="o">/</span><span class="n">make_parallel</span><span class="o">.</span><span class="n">py</span> <span class="n">http</span><span class="p">:</span><span class="o">//</span><span class="n">localhost</span><span class="p">:</span><span class="mi">8001</span> <span class="n">test</span> <span class="n">test</span><span class="o">.</span><span class="n">alc</span> <span class="n">bootstrap</span><span class="o">/</span><span class="n">primitives</span><span class="o">.</span><span class="n">alc</span>
<span class="n">python</span> <span class="n">scripts</span><span class="o">/</span><span class="n">prompt</span><span class="o">.</span><span class="n">py</span>
</pre></div>
</div>
<p>In the prompt, log on to <a class="reference external" href="http://localhost:8001">http://localhost:8001</a> as user <em>test</em>.
Now, all input you send, will be caught in the <em>input()</em> calls seen in the code.
Results will also be printed.</p>
<p>Note that all content will, by default, be typed as string.
If you want to send integers or so, prepend the input with a backslash (\), which allows you to directly input the JSON code.
For example, input <em>5</em> will be received as the string &#8220;5&#8221;.
To send the integer 5, the input should be <em>\5</em>.</p>
<div class="section" id="fibonacci-server">
<h2>Fibonacci Server<a class="headerlink" href="#fibonacci-server" title="Permalink to this headline">¶</a></h2>
<p>The first example is a simple Fibonacci server.
The code is identical to the action language example from before, as this already included the <em>server</em> part (<em>i.e.</em>, the while loop).
Now we will just connect to it using <em>prompt.py</em> and try out the code directly.</p>
<p>The code is repeated below:</p>
<div class="highlight-default"><div class="highlight"><pre>include &quot;primitives.alh&quot;

Integer function fib(param : Integer):
    if (param &lt;= 2):
        return 1!
    else:
        return fib(param - 1) + fib(param - 2)!

Void function main():
    while(True):
        output(fib(input()))
</pre></div>
</div>
<p>To run this code, save it to a file (<em>e.g.</em>, fibonacci.alc) and execute the following command:</p>
<div class="highlight-default"><div class="highlight"><pre><span class="n">python</span> <span class="n">scripts</span><span class="o">/</span><span class="n">run_local_modelverse</span><span class="o">.</span><span class="n">py</span> <span class="mi">8001</span>
</pre></div>
</div>
<p>Now, the Modelverse is running, but we still need to upload our code.
To compile the file, together with the primitives.alc file, execute the following command:</p>
<div class="highlight-default"><div class="highlight"><pre><span class="n">python</span> <span class="n">scripts</span><span class="o">/</span><span class="n">make_parallel</span><span class="o">.</span><span class="n">py</span> <span class="n">http</span><span class="p">:</span><span class="o">//</span><span class="n">localhost</span><span class="p">:</span><span class="mi">8001</span> <span class="n">test</span> <span class="n">fibonacci</span><span class="o">.</span><span class="n">alc</span> <span class="n">bootstrap</span><span class="o">/</span><span class="n">primitives</span><span class="o">.</span><span class="n">alc</span>
</pre></div>
</div>
<p>When this finishes, the Modelverse now stores a copy of our code in its own format.
The Modelverse will automatically create the user <em>test</em> and start executing the <em>main</em> function as this user.
We can therefore simply connect to the Modelverse as the <em>test</em> user and start seeing the responses.
To start the prompt, execute the following command:</p>
<div class="highlight-default"><div class="highlight"><pre><span class="n">python</span> <span class="n">scripts</span><span class="o">/</span><span class="n">prompt</span><span class="o">.</span><span class="n">py</span>
</pre></div>
</div>
<p>In this prompt tool, you first have to configure the location of the Modelverse and the username.
The defaults should be fine, so just press &lt;return&gt; twice.
After that, you are in direct connection with the Modelverse.
Each message you type in, is made available in the <em>input()</em> function of the code.
Remember that, to send integers, you have to prefix this with a backslash (\).
To get, for example, the 1st Fibonacci number, type in the command:</p>
<div class="highlight-default"><div class="highlight"><pre>\<span class="mi">1</span>
</pre></div>
</div>
<p>You will now see the following.</p>
<img alt="_images/prompt_fibonacci.png" src="_images/prompt_fibonacci.png" />
<p>Since we are in an unconditional loop, you can send as many requests as you want, as long as they are understandable by the <em>fib</em> function.</p>
<img alt="_images/prompt_fibonacci_more.png" src="_images/prompt_fibonacci_more.png" />
<p>Inputting a string directly, such as <em>1</em> instead of <em>\1</em>, will make the Modelverse crash on the execution of this code.
This is normal, though in the future the Modelverse will keep running for other users: only the current user&#8217;s code will be interrupted.</p>
