Global variables were created as a way of speeding up playlist formatting, by separating the parts of formatting that is common to all your columns, and only processing it once instead of for each column. It works by defining variables which you can access in your column display strings.

Note: Information on the legacy format for global variables can be viewed here.

This string, in the globals configuration page, is where you define your variables.

You can set variables in your global variables string using the set_global function. The syntax is as follows:

$set_global(variable name,variable value)

Note: You can only define globals in the global string - i.e. you cannot access defined globals.

You must assign the variable value and then execute a print statement:

variable name=variable value;

print(“variable name=” # variable name # “”);

Looks strange, but that's the way to do it!

You can access global variables in your display and color strings using the get_global function. The syntax is as follows:

$get_global(variable name)

where

• variable name is the name of the variable as defined in the set_global function call
• the return value is the variable value

The syntax to access variable name is as follows:

extra(“variable name”)

where

• variable name is the name of the variable as defined in the Globals tab
• the return value is the variable value
