[ forgive me if it was sent twice. My first should be bounced as bad sender addr ].
Besides consistently forgetting how to properly spell "ternary", I
can't, for some reason, embed it's use into my brain no matter how much
I read.
Perhaps if someone could show me the way against a personal code snip, I
may finally "get it". What would this look like:
my $gst = $self->query->param( "gst${item_num}" );
my $pst = $self->query->param( "pst${item_num}" );
if ( $gst eq 'Yes' ) {
$gst = $self->tax_rate( 'gst' );
}
else {
$gst = 0;
}
if ( $pst eq 'Yes' ) {
$pst = $self->tax_rate( 'pst' );
}
else {
$pst = 0;
}
...in some cases I get it ( when reading code ). Then, shortly after
when I try it, my code breaks.
I'm thinking that I'm running into a precedence issue, but normally I
don't have so much trouble remembering a seemingly simple idiom.
Recently, I read this:
my $args = ( ref $_[0] eq 'HASH' ) ? shift : {} ;
Disregarding ( but acknowledging ) it's accompanying comment, is it fair
to rephrase it as such ( for my own understanding )?:
- if $_[0] is a hashref, shift @_ , and assign it to $args
- otherwise, assign an empty hashref ( anonymous ) to $args
