# SHARYANTO::Hash::Util(3pm)

Hash utilities

## NAME

SHARYANTO::Hash::Util - Hash utilities

## VERSION

This document describes version 0.77 of SHARYANTO::Hash::Util (from Perl distribution SHARYANTO-Utils), released on 2015-09-04.

## SYNOPSIS

```
 use SHARYANTO::Hash::Util qw(rename_key);
 my %h = (a=>1, b=>2);
 rename_key(\%h, "a", "alpha"); # %h = (alpha=>1, b=>2)
```

## FUNCTIONS

### rename\_key(\\%hash, $old\_key, $new\_key)

Rename key. This is basically `$hash{$new_key} = delete $hash{$old_key}` with a couple of additional checks. It is a shortcut for:

```
 die unless exists $hash{$old_key};
 die if     exists $hash{$new_key};
 $hash{$new_key} = delete $hash{$old_key};
```

### replace\_hash\_content($hashref, @pairs) =\> $hashref

Replace content in \<$hashref\> with `@list`. Return `$hashref`. Do not create a new hashref object (i.e. it is different from: `"$hashref = {new=>"content"}"`).

Do not use this function. In Perl you can just use: `"%$hashref = @pairs"`. I put the function here for reminder.
