Lua patterns deliberately lack the most complex regular expression constructs (to avoid bloating the Lua code base), where many other computer languages or libraries use a more complete set. Lua patterns are not even a subset of regular expressions, as there are also discrepancies, like Lua using the escape character % instead of \, , and ...

Unlike in wikicode, Lua does not use functions like #ifexpr and #expr. Add the Lua operators and functions straight into your module. Add the Lua operators and functions straight into your module. See mw:Help:Calculation for details on how #expr and mw . ext .
Only false and nil are false. Even "" is true. Tables can have both numeric and string entries. The two don't overlap. t [1] is distinct from t ["1"]. Uninitialized variables and nonexistent fields in tables are nil. or and and both have shortcut evaluation. = is assignment, == is equality comparison. not is boolean negation, but ~= is ...
This module provides utilities for declaring classes in Lua code. It creates global variables, so must be called before require ( 'strict' ) if that is used. The above documentation is transcluded from Module:Lua class/doc .
First we check-- to see if the value is memoized, and if not we try and fetch it from-- the argument tables. When we check memoization, we need to check-- metaArgs before nilArgs, as both can be non-nil at the same time.-- If the argument is not present in metaArgs, we also check whether-- pairs has been run yet. If pairs has already been run ...
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.
