This module is currently protected from editing.
See the protection policy and protection log for more details. Please discuss any changes on the talk page; you may submit an edit request to ask an administrator to make an edit if it is uncontroversial or supported by consensus. You may also request that this page be unprotected.

This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing.

This module is rated as alpha. It is ready for third-party input, and may be used on a few pages to see if problems arise, but should be watched. Suggestions for new features or changes in their input and output mechanisms 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.

The module may generate script errors -- whenever your call isn't valid Lua code, you see the error you would normally have. For example,

{{#invoke:LuaCall|main|value=1.4512|math.fmod(value)}} will produce Script error because the second value is lacking. No effort is made to trap these.

Ùsaid - Usage

{{#invoke:LuaCall|main|''arbitrary variables''|''parameters''|''function''}}

The arbitrary variables are any key of your choice = any value of your choice. Values are interpreted as strings unless tonumber(value) is not NaN - 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_return 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.

reserved_debug - nonzero value forces display of a not particularly useful debug text

The function 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.
