This document describes version 0.77 of SHARYANTO::Hash::Util (from Perl distribution SHARYANTO-Utils), released on 2015\-09\-04.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 3
\& use SHARYANTO::Hash::Util qw(rename_key);
\& my %h = (a=>1, b=>2);
\& rename_key(\e%h, "a", "alpha"); # %h = (alpha=>1, b=>2)

.ie n .SS "rename_key(\e%hash, $old_key, $new_key)"
.el .SS "rename_key(\e%hash, \f(CW$old_key\fP, \f(CW$new_key\fP)"
.IX Subsection "rename_key(%hash, $old_key, $new_key)"
Rename key. This is basically \f(CW$hash{$new_key} = delete $hash{$old_key}\fR
with a couple of additional checks. It is a shortcut for:
.PP
.Vb 3
\& die unless exists $hash{$old_key};
\& die if     exists $hash{$new_key};
\& $hash{$new_key} = delete $hash{$old_key};
.Ve
.ie n .SS "replace_hash_content($hashref, @pairs) => $hashref"
.el .SS "replace_hash_content($hashref, \f(CW@pairs\fP) => \f(CW$hashref\fP"
.IX Subsection "replace_hash_content($hashref, @pairs) => $hashref"
Replace content in <$hashref> with \f(CW@list\fR. Return \f(CW$hashref\fR. Do not create a
new hashref object (i.e. it is different from: \f(CW\*(C`$hashref = {new=>"content"}\*(C'\fR).
.PP
Do not use this function. In Perl you can just use: \f(CW\*(C`%$hashref = @pairs\*(C'\fR. I
put the function here for reminder.
