{{Module rating|alpha}}
{{shortcut|Module:LuaCall}}
This module allows you to call any one single preinstalled Lua function, so that you don't need to write a module for one desired feature.

==Usage==

===Main===
{{tlc|#invoke:LuaCall|main|{{var|arbitrary variables}}|{{var|parameters}}|{{var|functioncall}}}}

The {{var|arbitrary variables}} are any key of your choice <code>=</code> any value of your choice. Values are interpreted as strings unless {{code|tonumber(value)|lua}} isn't {{code|nil|lua}}, i.e. numbers should be converted to the numeric type. No effort is made to interpret tables.

The {{var|parameters}} all begin with <code>reserved_</code>, which arbitrary variable should use.

* <code>reserved_return</code> sets which output from the function you want, and defaults to 1. For example, setting it to 2 for mw.ustring.gsub will return the number of replacements made.
* <code>reserved_debug</code> - nonzero value forces display of a not particularly useful debug text

The {{var|functioncall}} is written as <code>{{var|some.function.name}}({{var|a,b,c}})</code> where {{var|some.function.name}} means something in the [[mw:Extension:Scribunto/Lua reference manual|Extension:Scribunto/Lua reference manual]] and {{var|a,b,c}} are the arbitrary variable names you've chosen.

==Examples==

===Main===
*{{demo inline|<nowiki>{{#invoke:LuaCall|main|a=test&nbsp;|b=7|string.rep(a,b)}}</nowiki>}}
*{{demo inline|<nowiki>{{#invoke:LuaCall|main|pattern=(%a)|replace=%1.|string=I can't get no satisfaction|mw.ustring.gsub(string,pattern,replace)|reserved_return=1}}</nowiki>}}
*{{demo inline|<nowiki>{{#invoke:LuaCall|main|pattern=(%a)|replace=%1.|string=I can't get no satisfaction|mw.ustring.gsub(string,pattern,replace)|reserved_return=2}}</nowiki>}}
*{{demo inline|<nowiki>{{#invoke:LuaCall|main|value=1.4512|math.ceil(value)}}</nowiki>}}
*{{demo inline|<nowiki>{{#invoke:LuaCall|main|value=1.4512|math.modf(value)}}</nowiki>}}
*{{demo inline|<nowiki>{{#invoke:LuaCall|main|value=1.4512|math.modf(value)|reserved_return=2}}</nowiki>}}
*{{demo inline|<nowiki>{{#invoke:LuaCall|main|mw.text.nowiki(s)|s={{URL|1=https://www.Amazon.com/}}}}</nowiki>}}

===Call===
*{{demo inline|<nowiki>{{#invoke:LuaCall|call|string.format|%04x|127}}</nowiki>}}
*{{demo inline|<nowiki>{{#invoke:LuaCall|call|math.modf|1.4512}}</nowiki>}}
*{{demo inline|<nowiki>{{#invoke:LuaCall|call|math.modf|1.4512|return=2}}</nowiki>}}

==Errors==
The module '''may''' generate script errors — whenever your call is not valid Lua code, you see the error you would normally have. For example,

{{demo inline|<nowiki>
{{#invoke:LuaCall|main|value=1.4512|math.fmod(value)}}</nowiki>}}

because the second value is lacking. No effort is made to trap these.
