<h1 id="chatscript">ChatScript</h1>
<p>Natural Language tool/dialog manager</p>
<p>ChatScript is the next generation chatbot engine that has won the Loebner's 4 times and is the basis for natural language company for a variety of tech startups.</p>
<p>ChatScript is a rule-based engine, where rules are created by humans writers in program scripts through a process called dialog flow scripting. These use a scripting metalanguage (simply called a "script") as their source code. Here what a ChatScript script file looks like:</p>
<pre><code>#
# file: food.top
#
topic: ~food []
#! I like spinach
s: ( I like spinach ) Are you a fan of the Popeye cartoons?
a: ( ~yes ) I used to watch him as a child. Did you lust after Olive Oyl?
b: ( ~no ) Me neither. She was too skinny.
b: ( yes ) You probably like skinny models.
a: ( ~no ) What cartoons do you watch?
b: ( none ) You lead a deprived life.
b: ( Mickey Mouse ) The Disney icon.
#! I often eat chicken
u: ( ![ not never rarely ] I * ~ingest * ~meat ) You eat meat.
#! I really love chicken
u: ( !~negativeWords I * ~like * ~meat ) You like meat.
#! do you eat bacon?
?: ( do you eat _ [ ham eggs bacon] ) I eat '_0
#! do you like eggs or sushi?
?: ( do you like _* or _* ) I don't like '_0 so I guess that means I prefer '_1.
#! I adore kiwi.
s: ( ~like ~fruit ![~animal _bear] ) Vegan, you too...
#! do you eat steak?
?: ( do you eat _~meat ) No, I hate _0.
#! I eat fish.
s: ( I eat _*1 > )
$food = '_0
I eat oysters.</code></pre>

</ul>
<h1 id="getting-started">Getting started</h1>
<h2 id="installation">Installation</h2>
<p>Take this project and put it into some directory on your machine (typically we call the directory ChatScript, but you can name it whatever). That takes care of installation.</p>
<pre><code>git clone https://github.com/bwilcox-1234/ChatScript</code></pre>
<h2 id="standalone-mode---run-locally-on-a-console-for-developementtest">Standalone mode - run locally on a console (for developement/test)</h2>
<p>From your ChatScript home directory, go to the BINARIES directory:</p>
<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash"><span class="bu">cd</span> BINARIES</code></pre></div>
<p>And run the ChatScript engine</p>
<h3 id="windows">Windows</h3>
<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash"><span class="ex">ChatScript</span></code></pre></div>
<h3 id="linux">Linux</h3>
<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash"><span class="ex">./LinuxChatScript64</span> local</code></pre></div>
<p>Note: to set the file executable: <code>chmod a+x ./LinuxChatScript64</code></p>
<h3 id="macos">MacOS</h3>
<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash"><span class="ex">./MacChatScript</span> local</code></pre></div>
<p>This will cause ChatScript to load and ask you for a username. Enter whatever you want. You are then talking to the default demo bot <code>Harry</code>.</p>
<h2 id="server-mode-for-production">Server Mode (for production)</h2>
<p>From your ChatScript home directory, go to the BINARIES directory and run the ChatScript engine as server ### Run the server on Windows</p>
<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash"><span class="ex">ChatScript</span> port=1024</code></pre></div>
<h3 id="run-the-server-on-linux">Run the server on Linux</h3>
<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash"><span class="ex">./LinuxChatScript64</span></code></pre></div>
<h3 id="run-the-server-on-macos">Run the server on MacOS</h3>
<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash"><span class="ex">./MacChatScript</span></code></pre></div>
<p>This will cause ChatScript to load as a server.<br />
But you also need a client (to test client-server communication). You can run a separate command window and go to the BINARIES directory and type</p>
<h3 id="run-a-client-test-on-windows">Run a client (test) on Windows</h3>
<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash"><span class="ex">ChatScript</span> client=localhost:1024 </code></pre></div>
<h3 id="run-a-client-test-on-linux">Run a client (test) on Linux</h3>
<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash"><span class="ex">./LinuxChatScript64</span> client=localhost:1024</code></pre></div>
<h3 id="run-a-client-test-on-macos">Run a client (test) on MacOS</h3>
<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash"><span class="ex">./MacChatScript</span> client=localhost:1024</code></pre></div>
<p>This will cause ChatScript to load as a client and you can talk to the server.</p>
<h2 id="how-to-build-a-bot">How to build a bot</h2>
<p>Run ChatScript locally. From the ChatScript command prompt, type</p>
<pre><code>:build Harry</code></pre>
<p>or whatever other preinstalled bot exists. If you have revised basic data, you can first:</p>
<pre><code>:build 0</code></pre>
<h2 id="how-to-compile-the-engine.">How to compile the engine.</h2>
<p>On windows if you have Visual Studio installed, launch <code>VS2010/chatscript.sln</code> or <code>VS2015/chatscript.sln</code> and do a build. The result will go in the <code>BINARIES</code> directory.</p>
<p>On Linux, go stand in the SRC directory and type <code>make server</code> (assuming you have make and g++ installed). This creates BINARIES/ChatScript, which can run as a server or locally. There are other make choices for installing PostGres or Mongo.</p>
