The string-search functions in Lua script can run extremely fast, comparing millions of characters per second. For example, a search of a 40,000-character article text, for 99 separate words (passed as 99 parameters in a template), ran within one second of Lua CPU clock time.
Finally, since we expected that other Tecgraf products would also need to embed a scripting language, the new language should follow the example of SOL and be provided as a library with a C API. Lua 1.0 was designed in such a way that its object constructors, being then slightly different from the current light and flexible style, incorporated ...
The script at Module:LuaCall has been written to accept any set of named parameters somename=value, for each one storing the string value in the variable with the name somename, and then allowing you to use these variables as parameters for any function available in Lua. The script then returns only the first value returned by the function (Lua ...
The Simplified Wrapper and Interface Generator (SWIG) is an open-source software tool used to connect computer programs or libraries written in C or C++ with scripting languages such as Lua, Perl, PHP, Python, R, Ruby, Tcl, and other language implementations like C#, Java, JavaScript, Go, D, OCaml, Octave, Scilab and Scheme.

If it isn't a table, it's a string, a number, a boolean, a function, or a nil. Libraries are tables. string.gmatch is the "gmatch" entry in the table named by the global variable string. Arguments that you receive from MediaWiki are tables. But they're a bit special. Arrays are tables that follow a specific convention.
So, much of what these books explain about Lua standard library functions and variables that come with the language is either irrelevant or untrue here. The original API specification — the Lua standard library functions and variables that are supposed to be available in modules — is given at MW:Extension:Scribunto/API specification ...
