Konstrukt::Plugin::perlvar - Access to Perl variables
Usage:
<!-- set value --> <& perlvar var="$Foo::Bar" set="baz" / &> <!-- print out value --> <& perlvar var="$Foo::Bar" / &> <& perlvar var="undef" &>this default will be used<& / &> <!-- unset value --> <& perlvar var="$Foo::Bar" unset="1" / &>
Result:
<!-- set value --> <!-- print out value --> baz this default will be used <!-- unset value -->
Plugin to support access to variables.
In fact the statement in the var-attribute is eval'ed. so when using it without set, the return value of any perl statement will be returned. Use it with care!
The date is a very volatile data. We don't want to cache it...
Parameters:
$tag - Reference to the tag (and its children) that shall be handled.
Checks the passed tag for attributes like var="varname" and set="value".
With only var being passed, the value of the will be put out.
With additionaly set being passed, the according value of the variable will be changed and nothing will be put out.
