SHARYANTO::Hash::Util - Hash utilities
This document describes version 0.77 of SHARYANTO::Hash::Util (from Perl distribution SHARYANTO-Utils), released on 2015-09-04.
use SHARYANTO::Hash::Util qw(rename_key); my %h = (a=>1, b=>2); rename_key(\%h, "a", "alpha"); # %h = (alpha=>1, b=>2)
Rename key. This is basically $hash{$new_key} = delete $hash{$old_key} with a couple of additional checks. It is a shortcut for:
$hash{$new_key} = delete $hash{$old_key}
die unless exists $hash{$old_key}; die if exists $hash{$new_key}; $hash{$new_key} = delete $hash{$old_key};
Replace content in <$hashref> with @list. Return $hashref. Do not create a new hashref object (i.e. it is different from: $hashref = {new=>"content"}).
$hashref
$hashref = {new=>"content"}
Do not use this function. In Perl you can just use: %$hashref = @pairs. I put the function here for reminder.
%$hashref = @pairs
