NAME
    Hash::Rename - Rename hash keys

VERSION
    version 1.100860

SYNOPSIS
        use Hash::Rename;

        my %hash = (
            '-noforce' => 1,
            scheme     => 'http'
        );
        hash_rename %hash, code => sub { s/^(?!-)/-/ };

DESCRIPTION
    Using this module you can rename a hash's keys in place.

FUNCTIONS
  hash_rename
    This function is automatically exported. It takes a hash to rename and
    another hash of instructions on how to rename they keys.

    The syntax is like this:

        hash_rename %hash, key1 => 'value1', keys2 => 'value2';

    The following instructions are supported:

    "prepend"
            hash_rename %hash, prepend => '-';

        The given value is prepended to each hash key.

    "append"
            hash_rename %hash, append => '-';

        The given value is appended to each hash key.

    "code"
            hash_rename %hash, code => sub { s/^(?!-)/-/ };

        Each hash key is localized to $_ and subjected to the code. Its new
        value is the result of $_ after the code has been executed.

    "strict"
        If present and set to a true value, the resulting keys are checked
        for duplicates. "hash_rename()" will die if it detects a duplicate
        resulting hash key. They keys of the hash to change are processed in
        alphabetical order.

    If several instructions are given, they are processed in the order in
    which they are described above. So you can have:

        hash_rename %hash, prepend => '-', append => '=';
