Module:LuaCall
 | This module is rated as alpha. It is ready for limited use and third-party feedback. It may be used on a small number of pages, but should be monitored closely. Suggestions for new features or adjustments to input and output are welcome. |
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
{{#invoke:Lua call|main|arbitrary variables|parameters|functioncall}}
The arbitrary variables are any key of your choice = any value of your choice. Values are interpreted as strings unless tonumber(value) isn't nil, i.e. numbers should be converted to the numeric type. No effort is made to interpret tables.
The parameters all begin with reserved_, which arbitrary variable should use.
reserved_returnsets 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.reserved_debug- nonzero value forces display of a not particularly useful debug text
The functioncall is written as some.function.name(a,b,c) where some.function.name means something in the Extension:Scribunto/Lua reference manual and a,b,c are the arbitrary variable names you've chosen.

Call
{{#invoke:Lua call|call|string.format|%04x|127}}→ 007f{{#invoke:Lua call|call|math.modf|1.4512}}→ 1{{#invoke:Lua call|call|math.modf|1.4512|return=2}}→ 1{{#invoke:lua call|call|mw.text.unstripNoWiki|<nowiki>[[Wikipedia]]</nowiki>}}→ Wikipedia
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,
{{#invoke:Lua call|main|value=1.4512|math.fmod(value)}} →
Lua error in Module:Lua_call at line 42: bad argument #2 to 'fn' (number expected, got no value).
because the second value is lacking. No effort is made to trap these.
