ZeroFrame

ZeroFrame(Forum) provides a way to organize, order, and loop over the other meta-scripts in the Meta-Toolbox. It can unpack inline rolls right in the command line, and lets you defer things like inline roll detection or the syntax token (the structures that would trigger the other meta-scripts) by escaping the text with a backslash(/).

Syntax:

!0 config              =>    displays the ZeroFrame configuration (showing script priorities and handles)
!0 sm|20               =>    sets the priority of SelectManager to 20
!0 logic|75 set|80     =>    multiple meta-scripts can be set in one statement (APILogic to 75, Muler Setting to 80)
{& 0 get sm }          =>    an inline tag for calls to another script changing the default loop order
                             for this call (only), the order will be Muler Get, SelectManager, then the other scripts in default order
.value                 =>    inline token to reduce an inline roll to its value (i.e., [[1d10]].value or $[[0]].value )
{& log}                =>    inline tag to output the ZeroFrame log
{& flat}               =>    send the resulting message to the chat (no further API interaction), only detected after the loop finishes
{& stop}               =>    stops further processing (no chat, no API); only detected after the loop finishes
{& escape ...}         =>    characters to be removed only as the message leaves the metascript loop
{& global ([term]def)} =>    term definition for text replacement (every loop pass)

Understanding MetaScripts and the ZeroFrame Loop

MetaScripts are scripts that operate on the message object prior to the message reaching the intended destination script. For instance, if you wanted to reference the 'top' value of a token within the text of a command line intended for another script, Roll20 does not offer a built-in syntax structure to retrieve that value. That is, there is no @{selected|top} construction you could use in your command line to reference that value. Fetch, a metascript, does offer a way to get the top value of a token: @(selected.top) , and since it is a metascript, it will return that information to the command line of the intended recipient script before that script examines the command line to determine what it needs to do.
