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 code in Scribunto is only run when the page is being parsed. Therefore, the only user input that Lua can receive is by page editing – it cannot create a box that calculates the square root of a number you type in, or recalculate a piece of the Mandelbrot set depending on which part of the parent set you click on. The input Lua can receive ...
This Lua module is used in system messages, and on approximately 30,200,000 pages, or roughly 49% of all pages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox .

Core uses Lua for user scripts. [5] CRYENGINE uses Lua for user scripts. [6] Custom applications for the Creative Technology Zen X-Fi2 portable media player can be created in Lua. Damn Small Linux uses Lua to provide desktop-friendly interfaces for command-line utilities without sacrificing much disk space.
Here are some short points about Lua, for those who already know other computer programming languages and how to program. They focus mainly upon what you might find different in Lua. Lua is dynamically typed. There's no static typing at all.
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 ...
