==== Complex scripted_triggers ====

Scripted_triggers can also have a complex form that handles literal text replacement, allowing to pass arguments.

For example, if the following set of triggers are used to check that the current character scope is a vassal of the King of France and related to them:

<pre>is_vassal_of = title:k_france.holder
is_close_family_of = title:k_france.holder</pre>
that set of triggers can be defined as a scripted_trigger, but instead of referencing <code>title:k_france.holder</code> specifically, the scripted_trigger uses an argument defined in uppercase letters wrapped in two <code>$</code> signs:
<pre>is_related_vassal_of = {
   is_vassal_of = $TARGET$
   is_close_family_of = $TARGET$
}</pre>
When used, the complex form of the scripted_trigger specifies what the expected argument is, by using the same name but without the <code>$</code> signs:
<pre>is_related_vassal_of = {
   TARGET = title:k_france.holder
}</pre>

With that form, every occurrence of <code>$TARGET$</code> in the scripted_trigger  will be ''literally'' replaced with the argument provided: the text replacement happens ''before'' the scripted_trigger is evaluated.
