NAME

Hash::KeyMorpher - Deep converter for naming conventions of hash keys

DESCRIPTION

Deeply change the nameing conventions for keys in hash structures, or simply change strings between naming conventions. Converts to CamelCase, mixedCamel, delimited_string, UPPER, LOWER

SYNOPSYS

    use Hash::KeyMorpher; # import all, or
    use Hash::KeyMorpher qw (key_morph to_camel to_mixed  to_under to_delim); # import specific subs

    # To use the string converters:
    $res = to_camel('my_string'); # MyString
    $res = to_mixed('my_string'); # myString
    $res = to_under('myString');  # my_string
    $res = to_delim('myString','-');  # my-string

    # To morph keys in a hash, key_morph($hash,$method,$delim);
    # method is one of camel,mixed,under,delim,upper,lower
    $h1 = { 'level_one' => { 'LevelTwo' => 'foo' } };
    $mixed = key_morph($h1,'mixed');  # { 'levelOne' => { 'levelTwo' => 'foo' } };
    $delim = key_morph($h1,'delim','-');  # { 'level-one' => { 'level-two' => 'foo' } };
    
    # To morph acceccor keys
    $obj = Hash::Accessor->new(qw /CamelCase mixedCase delim_str UPPER lower/);
    $camel = key_morph($obj,'camel');
    

EXPORT

This module exports key_morph, to_camel, to_mixed, to_under and to_delim. You will probably only need key_morph unless you really want the others.

FUNCTIONS

_split_words($str)

Splits a string into words, identifying boundaries using Capital Letters or Underscores etc. This sub is not exported

key_morph($hash,$method,$delim)

$method can be one of (camel, mixed, delim, upper, lower). $delim should be specified if using the delim method; by default its an empty string.

to_camel($str)

Convers string to CamelCase

to_mixed($str)

Convers string to mixedCamelCase

to_under($str)

Convers string to underscore_separated

to_delim($str,$delim)

Convers string to custom delimited-string (delimited by second parameter)

to_upper($str)

Returns the uppercase version of the rejoined string (removes undescores etc)

to_lower($str)

Returns the lowercase version of the rejoined string (removes undescores etc)
