NAME

Hash::RenameKey - Perl extension for recursively renaming keys according to a regex pattern match

SYNOPSIS

            

              
              
use Hash::RenameKey;
my $hr = Hash::RenameKey->new;
my $old = '-';
my $new = '_';
$hr->rename_key(\%hash, $old, $new);
            
          

DESCRIPTION

This module provides a single function, rename_key, to recursively rename keys in a hash by applying a regex as follows:

            

              
              
s/$old/$new/g;
            
          

EXPORT

Nothing is exported. This module uses an OO interface.
