Editing WoW:UI FAQ/Macros and scripts (section)

=== Scripts ===
Usually, not just in WoW, the term Script refers to a short to medium length program, written in some kind of simple programming language (called a scripting language). The purpose of a script is usually to control another program.

World of Warcraft has a powerful programming language called [[Lua]] embedded inside it, which is used for scripting. What this means is that WoW is able to understand and execute little programs written in the Lua language. However, in WoW, a script is usually not something that you use by itself, i.e. you don't just type in a script and execute it (although this is also possible). Instead, there are several places in WoW where you have the option to enter scripts as part of something else.

The kind of places that you can use a script:

;/script [command]
: If you type the slash command "/script" in the chat box, you can follow it with one or more valid Lua language statements (i.e. a script).

;Macros
: you can enter scripts as part of macros, by putting one or more "/script" commands in your macro.

So what can a script do? There are many resources on Lua scripts. However, the most important point is that scripts are able to perform many more game actions than slash commands. This is done via a set of functions (called API or Application Programming Interface) that WoW makes available for use in scripts. There is a quite extensive list of all the API functions available for use in scripts at https://addonstudio.fandom.com/WoW_customization

'''NOTE: Scripts are now mainly reserved for UI, the allowable API used within the /script tag is greatly reduced. It is however still usable.'''

If you wish to create a macro to cast spells or use an item, refer to the [[Most_Used_Macros#2.0_Macro_Guide|2.0 Macro guide]]. The majority of the new limitations on the "/Script" tag cover these actions. For miscellaneous actions such as switching weapons, playing music, or sending chat messages; scripts still work fine. --Digital Utopia 05:25 2 February 2007 (CST)
