Data::Default version 0.11
=========================
NAME
Data::Default -- Small utility for getting the default value of an
argument or variable.
SYNOPSIS
use Data::Default ':all';
# variables
my ($var);
# later...
if (default $var, 1) {
# stuff if the $var is undef or set to a true value
}
else {
# stuff if the $var is defined and set to true
}
DESCRIPTION
Just a little utility for getting the default value of an argument or
parameter. All it really does is accept an array of arguments, then
return the first argument that is defined.
This function is usually used in a subroutine to get the default value
of a parameter. A typical usage would be in a subroutine like this:
sub mysub {
my (%opts) = @_;
if (default $opts{'some-option'}, 1) {
# do stuff some-option was sent and was true or was not sent
}
else {
# do stuff some-option was sent and was false
}
}
You might prefer to use "Attribute::Default" by Stephen Nelson which
provides similar functionality.
INSTALLATION
