<h2>Usage</h2>
<h3>Runtime library</h3>
<p>All parsing code for Ruby generated by Kaitai Struct depends on the
<a
href="https://github.com/kaitai-io/kaitai_struct_ruby_runtime/"
target="_blank" rel="noopener">
Ruby runtime library</a>. You have to
install it before you can parse data.</p>
<p>The Ruby runtime library can be installed <a href="https://rubygems.org/gems/kaitai-struct"
target="_blank" rel="noopener">from RubyGems</a>:</p>
<pre><code>gem install kaitai-struct</code></pre>
<h3>Code</h3>
<p>Parse a local file and get structure in memory:</p>
<div class="highlight"><pre><span></span><span class="n">data</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="no">DoomWad</span><span class="o">.</span><span class="n">from_file</span><span class="p">(</span><span class="s2">"path/to/local/file.wad"</span><span class="p">)</span>
</pre></div>
<p>Or parse structure from a string of bytes:</p>
<div class="highlight"><pre><span></span><span class="n">bytes</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="s2">"</span><span class="se">\x00\x01\x02</span><span class="s2">..."</span>
<span class="n">data</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="no">DoomWad</span><span class="o">.</span><span class="n">new</span><span class="p">(</span><span class="no">Kaitai</span><span class="o">::</span><span class="no">Struct</span><span class="o">::</span><span class="no">Stream</span><span class="o">.</span><span class="n">new</span><span class="p">(</span><span class="n">bytes</span><span class="p">))</span>
</pre></div>
<p>After that, one can get various attributes from the structure by invoking getter methods like:</p>
<div class="highlight"><pre><span></span><span class="n">data</span><span class="o">.</span><span class="n">num_index_entries</span><span class="w"> </span><span class="c1"># => Number of entries in the lump index</span>
</pre></div>
