API RunScript

Executes a string of Lua code. RunScript(script)

• script: - The code which is to be executed.

• To define a function dynamically you could do:

local retExpr = '"Hello " .. UnitName("target")'; RunScript("function My_GetGreeting return " .. retExpr .. ";end");

• The My_GetGreeting function will be defined to return Hello followed by the name of your target.

• This function is NOT recommended for general use within addons for a number of reasons:

• 1. It'll do whatever you tell it, that includes calling functions, setting variables, whatever.

• 2. Errors in the script string produce the error popup (at least, they produce the UI_ERROR_MESSAGE event).

• On the other hand, it's invaluable if you need to run code that is input by the player at run-time, or do self-generating code.

• The standard Lua function API loadstring, which can overcome all of the problems of RunScript described above.
