Lua (/ ˈ l uː ə / LOO-ə; from Portuguese: lua meaning moon) is a lightweight, high-level, multi-paradigm programming language designed mainly for embedded use in applications. [3] Lua is cross-platform software , since the interpreter of compiled bytecode is written in ANSI C , [ 4 ] and Lua has a relatively simple C application programming ...
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 ...

Lua is dynamically typed. There's no static typing at all. From a syntactic point of view, think BASIC (or even COMAL) without line numbers and colons rather than C/C++/Java, Lisp/Scheme, or Forth. There's no begin, but most control structures have an end; for needs a do and if needs a then. {...} denote a table (expression), not a block of code.
In video game development, Lua is widely used as a scripting language by game programmers, perhaps due to its perceived easiness to embed, fast execution, and short learning curve. [1] In 2003, a poll conducted by GameDev.net showed Lua as the most popular scripting language for game programming. [2]

This help-page, Help:Lua debugging, explains issues of writing Lua script and debugging the source code, to remove errors or improve performance. Because Lua is a "semi-compiled" interpreted language, it does not prescreen for all common syntax errors, nor detect misspelled variables, which are only found at runtime when seeing the " Script ...
