Thanx, I'll try and absorb that.
I'm getting closer to the answer. I can see what's happening but I
struggled to get at the hash. I got there in the end,
sub someFunc {
use Data::Dumper;
print STDERR Dumper(@_);
print STDERR "Last el=". ref($_[-1])."\n";
my $args = (ref($_[-1]) eq 'HASH') ? pop : @_;
foreach (keys %{$args}) {
print STDERR "someFunc: $args->{$_} => $_\n";
}
}
$VAR1 = {
'lid' => '69264',
'perpage' => 24
};
Last el=HASH
someFunc: 69264 => lid
someFunc: 24 => perpage
$VAR1 = {
'lid' => '69264',
'perpage' => 48
};
Last el=HASH
someFunc: 69264 => lid
someFunc: 48 => perpage
$VAR1 = {
'lid' => '69264',
'perpage' => 96
};
Last el=HASH
someFunc: 69264 => lid
someFunc: 96 => perpage
I have a problem now in that the function is used elsewhere but called as
SomeMod::someFunc(lid=>$lid, perpage=>'12').
I want to maintain that compatibility. I'll need to coerce the
reference into an normal hash or vice-verse. I guess that's a question
for another list.
Thanx for all the help though,
Dp.
