Just write parent=frame.getParent(frame) and parent.args will contain those arguments. It is popular in Lua to use the synonymous statement parent=frame:getParent(), cancelling the need to write frame twice. Note the colon (:) instead of the dot (.). parent=frame:getParent() means exactly the same as parent=frame.getParent(frame). For novices ...
A "Hello, World!"program is generally a simple computer program that emits (or displays) to the screen (often the console) a message similar to "Hello, World!".A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax.
Computer programming is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [ 1 ] [ 2 ] It involves designing and implementing algorithms , step-by-step specifications of procedures, by writing code in one or more programming languages .
In computing, a script is a relatively short and simple set of instructions that typically automate an otherwise manual process. The act of writing a script is called scripting . Scripting language or script language describes a programming language that is used for scripting.
Lua scripts may load extension modules using require, [20] just like modules written in Lua itself, or with package.loadlib. [22] When a C library is loaded via require ( 'foo' ) Lua will look for the function luaopen_foo and call it, which acts as any C function callable from Lua and generally returns a table filled with methods.

Starting out, it may be easier to modify an existing script to do what you want, rather than create a new script from scratch. This is called "forking". To do this, copy the script to a subpage, ending in ".js", [ n. 1 ] of your user page.
This page will collect various techniques for achieving common tasks needed in writing user scripts. Discussion about limitations, relative portability, and speed of the various alternatives is strongly encouraged. There is a lot of duplication and non-optimal efforts out there, and this will hopefully encourage us to write tighter, more ...
