<p>Documentation</p> <p><b>New page</b></p><div>Computes the CRC32 checksum of a string, as lowercase hexadecimal without leading zeros. [[Template:Inline spoiler|&lt;nowiki&gt;{{Inline spoiler}}&lt;/nowiki&gt;]] uses it to build an id from the spoiler&#039;s text, which links the toggle to the hidden text. Two spoilers with the same text on one page therefore get the same id.<br /> <br /> * &lt;code&gt;crc(frame)&lt;/code&gt;: &lt;code&gt;&lt;nowiki&gt;{{#invoke:Hash|crc|text}}&lt;/nowiki&gt;&lt;/code&gt; returns the checksum of &lt;code&gt;text&lt;/code&gt;.<br /> * &lt;code&gt;crc_internal(str)&lt;/code&gt;: the same for Lua. It returns the string &lt;code&gt;&quot;nil&quot;&lt;/code&gt; when &lt;code&gt;str&lt;/code&gt; is &lt;code&gt;nil&lt;/code&gt;.<br /> &lt;includeonly&gt;<br /> &lt;!-- Categories below this line --&gt;<br /> <br /> &lt;/includeonly&gt;&lt;noinclude&gt;<br /> [[Category:Module documentation pages]]<br /> &lt;/noinclude&gt;</div>
