i.e the boolean values that had a default of 1 could not be overridden
from the calling template. All other values/types were overridable. Any
ideas?
From the docs:
"The DEFAULT directive is similar to SET but only updates variables that are currently
undefined or have no "true" value (in the Perl sense)."
http://www.template-toolkit.org/docs/plain/Manual/Directives.html
The part to note there is the last part about having no "true" value (in the
Perl sense). Which means, '', 0 and undef.
The reason is that default is doing something like this:
if (!passed_in_MY_BOOL_D1){
MY_BOOL_D1 = default_MY_BOOL_D1
}
Since the ! evaluates to true when passed_in_MY_BOOL_D1 is 0, you would see the behavior you saw.
