<a href=#introduction class=heading-link><i class="fas fa-paperclip"></i></a></h3><p>Commander is a library for writing custom commands in Lua.
In order to make it easier to write commands for Hilbish,
not require separate scripts and to be able to use in a config,
the Commander library exists. This is like a very simple wrapper
that works with Hilbish for writing commands. Example:</p><div class=highlight><pre tabindex=0 style=color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4><code class=language-lua data-lang=lua><span style=display:flex><span><span style=color:#66d9ef>local</span> commander <span style=color:#f92672>=</span> require <span style=color:#e6db74>&#39;commander&#39;</span>
</span></span><span style=display:flex><span>
</span></span><span style=display:flex><span>commander.register(<span style=color:#e6db74>&#39;hello&#39;</span>, <span style=color:#66d9ef>function</span>(args, sinks)
</span></span><span style=display:flex><span> sinks.out:writeln <span style=color:#e6db74>&#39;Hello world!&#39;</span>
</span></span><span style=display:flex><span><span style=color:#66d9ef>end</span>)
</span></span></code></pre></div><p>In this example, a command with the name of <code>hello</code> is created
that will print <code>Hello world!</code> to output. One question you may
have is: What is the <code>sinks</code> parameter?</p><p>The <code>sinks</code> parameter is a table with 3 keys: <code>in</code>, <code>out</code>,
and <code>err</code>. The values of these is a <a href=/Hilbish/docs/api/hilbish/#sink style=text-decoration:none>Sink</a>.</p><ul><li><code>in</code> is the standard input. You can read from this sink
to get user input. (<strong>This is currently unimplemented.</strong>)</li><li><code>out</code> is standard output. This is usually where text meant for
output should go.</li><li><code>err</code> is standard error. This sink is for writing errors, as the
name would suggest.</li></ul><h3 id=functions class=heading>Functions
