Hi,
I am trying to build a hash(ref) and while doing so I want to remove
any white space from strings such as "1280 x 1024". So I have
my $record = {
contributor => $resolution,
....
};
Perhaps I am trying to be too clever but I thought I could do
my $record = {
contributor => $resolution =~ s/\s+//g,
But my value ends up as 2, the number of white space matches I guess.
Is this a question on context, scalar or list? Or is this sort of
assignment over-stretching things?
It will return 2 regardless of context. But speaking of assignment,
what about when you first set the resolution ...
( my $resolution = "1280 x 1024" ) =~ s/\s+//g;
my $record = {
contributor => $resolution,
};
or if you use the resolution for other things first, a sub ...
sub strip{ s/\s+//g for @_; @_ }
my $record = {
contributor => strip $resolution,
};
of if you don't really want to change the resolution ...
sub strip{ ( my $s = shift ) =~ s/\s+//g; $s }
my $record = {
contributor => strip $resolution,
};
or something silly for grins ...
my $record = {
contributor => scalar( $resolution =~ s/\s+//g, $resolution ),
};
