Scribunto Lua reference manual; Programming in Lua; Introduction to Lua patterns; About regex. Lua "patterns" are based on Regex (Patterns are a reduced set of regex). Help:Lua metamodules: Lua in Wikipedia has several meta-modules available that can make core functions easily available.
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 ...
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.
Marshalling data between C and Lua functions is also done using the stack. To call a Lua function, arguments are pushed onto the stack, and then the lua_call is used to call the actual function. When writing a C function to be directly called from Lua, the arguments are read from the stack.

In Scratch 1.4, an *.sb file was the file format used to store projects. [67] An *.sb file is divided into four sections: "header", this 10-byte header contains the ASCII string "ScratchV02" in versions higher than Scratch 1.2, and "ScratchV01" in Scratch 1.2 and below "infoSize", encodes the length of the project's infoObjects.
New versions of SciTE editor can be extended using Lua. Snort intrusion detection system includes a Lua interpreter since 3.0 beta release. [31] The Squeezebox music players from Logitech support plugins written in Lua on recent models (Controller, Radio and Touch). Stormworks: Build and Rescue use Lua for microcontrollers scripting / monitor ...
Also, all Lua in the page is limited to 10 seconds CPU time (you can look in the source code of a rendered page to see how long a template or module took to parse). And relative to standard Lua, Scribunto's Lua lacks all sorts of functions (see mw:Extension:Scribunto/Lua reference manual § Differences from standard Lua).
