Documentation

This module and its documentation are slightly modified versions what Google's AI Overview returned for the prompt "simple Lua module to call a MediaWiki template for any number of input parameters". They will both be improved "soon".

Explanation

• local p = {}: Initializes an empty table p which will hold the module's functions.
• function p.call(frame): Defines a function call within the table p. This function will be called by {{#invoke:CallTemplate|call}}. The frame object provides access to arguments and other MediaWiki functionalities.
• local args = frame.args: Retrieves the arguments passed to the {{#invoke:}} call as a table.
• local templateName = args[1]: Assumes the first positional argument is the name of the template to be called.
• local templateArgs = {}: Creates an empty table to store the arguments intended for the target template.
• for i, v in ipairs(args) do ... end: Iterates through the arguments passed to the module. It skips the first argument (the template name) and adds the rest to templateArgs.
• local templateCall = "{{" .. templateName ... "}}": Constructs the wikitext string for the template call, dynamically adding the arguments.
• return frame:preprocess(templateCall): This is the core of calling the template. frame:preprocess() instructs MediaWiki to parse and expand the provided wikitext string, effectively calling the specified template with the collected arguments.

Usage in Wikitext

{{#invoke:CallTemplate|call|MyTemplate|Parameter1|Parameter2|NamedParameter=Value}}

This example would call Template:MyTemplate with Parameter1, Parameter2, and NamedParameter=Value as its arguments.
