Template::Plugin::Assert - trap undefined values
SYNOPSIS
[% USE assert %]
# throws error if any undefined values are returned
[% object.assert.method %]
[% hash.assert.key %]
[% list.assert.item %]
DESCRIPTION
This plugin defines the "assert" virtual method that can be used to automatically throw errors when undefined values are used.
For example, consider this dotop:
[% user.name %]
If "user.name" is an undefined value then TT will silently ignore the fact and print nothing. If you "USE" the "assert" plugin then you
can add the "assert" vmethod between the "user" and "name" elements, like so:
[% user.assert.name %]
Now, if "user.name" is an undefined value, an exception will be thrown:
assert error - undefined value for name
