=== Modules ===
Besides standard library (core) modules it is possible to write extensions using the Lua API. Extension modules are [[Library (computing)#Dynamic linking|shared objects]] which can be used to extend the functions of the interpreter by providing native facilities to Lua scripts. Lua scripts may load extension modules using <code>require</code>,<ref name="luarefman"/> just like modules written in Lua itself, or with <code>package.loadlib</code>.<ref>{{Cite web |title=Lua 5.4 Reference Manual |url=https://www.lua.org/manual/5.4/manual.html#pdf-package.loadlib |first1=Roberto |last1=Ierusalimschy |first2=Luiz Henrique |last2=de Figueiredo |first3=Waldemar |last3=Celes |access-date=2022-06-01 |website=Lua}}</ref> When a C library is loaded via {{ml-lua|foo}} Lua will look for the function <code>luaopen_foo</code> and call it, which acts as any C function callable from Lua and generally returns a table filled with methods. A growing set of modules termed ''rocks'' are available through a [[package management system]] named [[LuaRocks]],<ref>{{cite web |url=https://luarocks.org/ |title=LuaRocks |publisher=luarocks.org |access-date=2009-05-24}}</ref> in the spirit of [[CPAN]], [[RubyGems]] and [[Python eggs]]. Prewritten Lua [[Language binding|bindings]] exist for most popular programming languages, including other scripting languages.<ref>{{cite web |url=http://lua-users.org/wiki/BindingCodeToLua |title=Binding Code To Lua |publisher=Lua-users wiki |access-date=2009-05-24 |url-status=dead |archive-url=https://web.archive.org/web/20090727080345/http://lua-users.org/wiki/BindingCodeToLua |archive-date= Jul 27, 2009}}</ref> For C++, there are a number of template-based approaches and some automatic binding generators.
