These individual modules are then invoked (by code <code>{{#invoke:<Module name>|<Function name>|(optional) param1 | param2...}}</code>). Example: </p> <table class="wikitable"> <tbody><tr> <th>Wikitext </th> <th>Result </th></tr> <tr> <td><code>{{#invoke:Example|hello}}</code> </td> <td>Hello World! </td></tr></tbody></table> <meta property="mw:PageProp/toc"/> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Running_a_module" data-mw-thread-id="h-Running_a_module"><span data-mw-comment-start="" id="h-Running_a_module"></span>Running a module<span data-mw-comment-end="h-Running_a_module"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Wikipedia:Lua&action=edit&section=1" title="Edit section's source code: Running a module"><span>change source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Modules are run on normal wiki pages using the #invoke parser function. The syntax of #invoke is similar to template syntax, but with some differences. The most important difference is that you need to specify a <i>function name</i>. A function is a set of instructions that takes input values, processes them, and returns an output value.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> This is much like what a template does: you give it arguments, it processes them, and you get a result. However, you can define many functions in one Lua module, whereas you can only define one template on one page. </p><p>Additionally, you can't just run a Lua module directly – you can only run one of the module's functions. The module is just a container for the functions, and doesn't do anything by itself. So there are two reasons that we need to input a function name: we can't run a module by itself, and without defining a function name, Lua will not know which function it is we want to run. </p><p>The simplest way to run a module from a wiki page is like this: </p> <pre>{{#invoke:<i>module name</i>|<i>function name</i>}} </pre> <p>For example, we can run <a href="/wiki/Module:Example" title="Module:Example">Module:Example</a> in this way, which has a function named "hello". </p> <ul><li><code>{{#invoke:Example|hello}}</code> → Hello World!</li></ul> <div class="mw-heading mw-heading3"><h3 id="Using_arguments" data-mw-thread-id="h-Using_arguments-Running_a_module"><span data-mw-comment-start="" id="h-Using_arguments-Running_a_module"></span>Using arguments<span data-mw-comment-end="h-Using_arguments-Running_a_module"></span></h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Wikipedia:Lua&action=edit&section=2" title="Edit section's source code: Using arguments"><span>change source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Arguments are passed to modules in the same way that they are passed to templates. Note, however, that the text after the first pipe character is always the function name; the first positional argument is the text after the <i>second</i> pipe. </p> <pre>{{#invoke:<i>module name</i>|<i>function name</i>|<i>first positional argument</i>|<i>second positional argument</i>|<i>named argument</i> = <i>value</i>}} </pre> <p>In <a href="/wiki/Module:Example" title="Module:Example">Module:Example</a>, the "hello_to" function greets different people depending on the first positional argument. It works like this: </p> <ul><li><code>{{#invoke:Example|hello_to|Kate}}</code> → Hello, Kate!</li> <li><code>{{#invoke:Example|hello_to|Fred}}</code> → Hello, Fred!</li></ul> <p>A third function in <a href="/wiki/Module:Example" title="Module:Example">Module:Example</a>, named has "count_fruit" uses the named arguments <code>bananas</code> and <code>apples</code> to count the number of bananas and apples we have. It can be run like this: </p> <ul><li><code>{{#invoke:Example|count_fruit|apples=3|bananas=4}}</code> → I have 4 bananas and 3 apples</li> <li><code>{{#invoke:Example|count_fruit|bananas=5|apples=2}}</code> → I have 5 bananas and 2 apples</li></ul> <p>Most modules have a documentation page explaining what arguments can be used and what their effects will be. </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Request_a_script" data-mw-thread-id="h-Request_a_script"><span data-mw-comment-start="" id="h-Request_a_script"></span>Request a script<span data-mw-comment-end="h-Request_a_script"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Wikipedia:Lua&action=edit&section=3" title="Edit section's source code: Request a script"><span>change source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Visit <b><a href="/w/index.php?title=Wikipedia_talk:Lua&action=edit&redlink=1" class="new" title="Wikipedia talk:Lua (not yet started)">Wikipedia talk:Lua</a></b> to request help in writing a Lua script to perform a specific task on Wikipedia or another Wikimedia Foundation project. </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="History" data-mw-thread-id="h-History"><span data-mw-comment-start="" id="h-History"></span>History<span data-mw-comment-end="h-History"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Wikipedia:Lua&action=edit&section=4" title="Edit section's source code: History"><span>change source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><a href="https://www.mediawiki.org/wiki/Manual:MediaWiki_architecture#Magic_words_and_templates" class="extiw" title="mw:Manual:MediaWiki architecture">Sordid history</a>. <span class="nowrap">{{</span><a href="/wiki/Template:Qif" title="Template:Qif">qif</a><span class="nowrap">}}</span>, <a href="https://www.mediawiki.org/wiki/Help:Extension:ParserFunctions" class="extiw" title="mw:Help:Extension:ParserFunctions">ParserFunctions</a>, <a href="https://www.mediawiki.org/wiki/Extension:Lua" class="extiw" title="mw:Extension:Lua">Lua extension</a>, wiki scripting language debated (JavaScript v.
