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 intended to be embedded into other applications, and provides a C API for this purpose. The API is divided into two parts: the Lua core and the Lua auxiliary library. [20] The Lua API's design eliminates the need for manual reference counting (management) in C code, unlike Python's API. The API, like the language, is minimalist.
They focus mainly upon what you might find different in Lua. 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 ...
LuaRocks is a package manager for the Lua programming language that provides a standard format for distributing Lua modules (in a self-contained format called a "rock"), a tool designed to easily manage the installation of rocks, and a server for distributing them. While not included with the Lua distribution, it has been called the "de facto ...
Roblox is an online game platform and game creation system built around user-generated content and games, [1] [2] officially referred to as "experiences". [3] Games can be created by any user through the platform's game engine, Roblox Studio, [4] and then shared to and played by other players. [1]

Step debugging is a powerful tool that allows you to step through code one line at a time, and hover over variables to see their contents at the time of execution. IDEs that easily support Lua step debugging include ZeroBrane Studio , and IntelliJ IDEA with various debugger plugins ( Emmy Lua or Lunalysis ).
