About

<pre class="sh_ruby"><code>
require 'parslet'
include Parslet
# Constructs a parser using a Parser Expression Grammar
parser = str('"') >>
(
str('\\').ignore >> any |
str('"').absent? >> any
).repeat.as(:string) >>
str('"')
result = parser.parse %Q("this is a valid \\"string\\"")
result # => {:string=>"this is a valid \"string\""@1}
</code></pre>
<p>A small Ruby library for constructing parsers in the
<a href="http://en.wikipedia.org/wiki/Parsing_expression_grammar"><span class="caps">PEG</span></a> (Parsing
Expression Grammar) fashion.</p>
<p>Parslet makes developing complex parsers easy. It does so by</p>
<ul>
<li>providing the best <strong>error reporting</strong> possible</li>
<li><strong>not generating</strong> reams of code for you to debug</li>
</ul>
<p>Parslet takes the long way around to make <strong>your job</strong> easier. It allows for
incremental language construction. Often, you start out small, implementing
the atoms of your language first; <em>parslet</em> takes pride in making this
possible.</p>
