PEG syntax quick reference

'x'   : match the literal character 'x'
x+    : match x 1 or more times
x*    : match x 0 or more times
x?    : match x 0 or 1 times
!x    : match anything but the match x
x/y   : match x or y, trying in that order
[xyz] : match one of the literal character 'x', 'y', or 'z'
v:x   : assign the result of the match x to the variable v

<title>Lazy Computer</title>

<h3>*Please be respectful for a computer.</h3>

<br/>
<hr/>
<h4>Basic syntax:</h4>

<b><span style="color:red;">ASK</span> <span style="color:green;">DO</span> <span style="color:blue;">WHAT</span> ? </b><br/>

<br/>
<hr/>

<h4 style="color:red;">ASK:</h4>

<p>If you casually ask, a computer returns casual value.<br/>
It's quicker way but be careful the use of casual returns because it's not so precise.<br/>
If you need to get an accurate value, use more formal way of asking.
</p>

<div style="font-style:italic;">Casual ask</div>
<li>hi</li>
<li>hey</li>
<li>yo</li>

<br/>

<div style="font-style:italic;">Formal ask</div>
<li>would you mind if I ask you to</li>
<li>could you please</li>
<li>may I ask you to</li>

<br/>
<hr/>

<h4 style="color:green;">DO</span> <span style="color:blue;">WHAT</span>:</h4>
<p>Currently only three DOs are active.</p>
<li><span style="color:green;">count</span> <span style="color:blue;">a</span> <span style="color:green;">to</span> <span style="color:blue;">b</span></li>
*Try to keep within 10 numbers if you want to casually ask.<br/>
<br/>
<li><span style="color:green;">add</span> <span style="color:blue;">a</span> <span style="color:green;">and</span> <span style="color:blue;">b</span></li>
*Do not ask too complicated numbers if you want to casually ask.<br/>
<br/>
<li><span style="color:green;">print</span> <span style="color:blue;">"a"</span></li>


<br/>
<hr/>

<h4><span>?</span>:</h4>
'?' at the end of your asking to distinguish with your monology. Prefered but optional.

<br/>
<br/>
<hr/>


<h4 style="">Important notes</span>:</h4>
<li>A lazy computer sometime didn't listen what you casually ask. In case, just say again or use formal ask.</li>
<li>You may want to ask to do more thing. Actually you can still ask but don't expect too much from a lazy computer.</li>

<br/>
<hr/>


<h4>Ask examples</h4>

<pre>hey count 5 to 10?</pre>
<pre>hi count 7 to 50?</pre>
<pre>would you mind if I ask you to count 7 to 50?</pre>

<pre>yo add 7123 and 4328?</pre>
<pre>could you please add 7123 and 4328?</pre>

<pre>hey print "hello world"?</pre>
<pre>may I ask you to print "hello world"?</pre>
