<p></p> <p><b>New page</b></p><div>{{documentation subpage}}<br /> This module computes and returns the cartesian product of multiple input sets (i.e., lists of strings), and then formats and combines the results into a single output string. Because this module was original developed to deal with locations, if a value in the first set contains a comma, a comma will be added to the end of that value before it is combined with a value from the second set.<br /> <br /> == Example ==<br /> It is called by {{tl|Combine categories}} to create category names from a list of locations and a list of topics.<br /> <br /> &lt;pre&gt;{{#invoke:Cartesian categories|combine<br /> | {{{location}}}<br /> | {{lc:{{{locality_subjects}}}}}<br /> | format = [[Category:%s %s]]<br /> }}&lt;/pre&gt;<br /> <br /> Input:<br /> &lt;syntaxhighlight &gt;{{Combine categories<br /> |location=Bucks County, Pennsylvania;Chester County, Pennsylvania;Pennsylvania<br /> |locality_subjects=Court records;Probate records;Vital records<br /> }}&lt;/syntaxhighlight &gt;<br /> <br /> Output: <br /> &lt;pre&gt;[[Category:Pennsylvania court records]]<br /> [[Category:Pennsylvania probate records]]<br /> [[Category:Pennsylvania vital records]]<br /> [[Category:Bucks County, Pennsylvania, court records]]<br /> [[Category:Bucks County, Pennsylvania, probate records]]<br /> [[Category:Bucks County, Pennsylvania, vital records]]<br /> [[Category:Chester County, Pennsylvania, court records]]<br /> [[Category:Chester County, Pennsylvania, probate records]]<br /> [[Category:Chester County, Pennsylvania, vital records]]<br /> &lt;/pre&gt;<br /> <br /> == See also ==<br /> * [[Module:Cartesian]]<br /> <br /> == Acknowledgements ==<br /> Original code provided by [https://stackoverflow.com/questions/79589576/best-way-to-explode-two-strings-and-create-combinations-of-values-from-each-stri/79590068#79590068 Alexander Mashin].</div>
