def acronym(word)

camelize 'mcdonald' #=> 'McDonald'
underscore 'McDonald' #=> 'mcdonald'
acronym 'McDonald'

camelize 'restful_controller' #=> 'RESTfulController'
camelize 'restful' #=> 'RESTful'
titleize 'RESTfulController' #=> 'RESTful Controller'
underscore 'RESTfulController' #=> 'restful_controller'
underscore 'RESTful' #=> 'restful'
acronym 'RESTful'
Examples:

capitalization. The only restriction is that the word must begin with a capital letter.
`acronym` may be used to specify any word that contains an acronym or otherwise needs to maintain a non-standard

camelize(pluralize('api')) #=> 'APIs'
acronym 'APIs'

camelize(pluralize('api')) #=> 'Apis'
acronym 'API'

acronym as well:
a delimited unit in the pluralized result. To work around this, you must specify the pluralized form as an
Note: Acronyms that are passed to `pluralize` will no longer be recognized, since the acronym will not occur as

underscore 'HTTPS' #=> 'https'
camelize 'https' #=> 'HTTPS'
acronym 'HTTPS'

underscore 'HTTPS' #=> 'http_s', not 'https'
camelize 'https' #=> 'Https', not 'HTTPs'
camelize 'my_http_delimited' #=> 'MyHTTPDelimited'
acronym 'HTTP'

The acronym, however, must occur as a delimited unit and not be part of another word for conversions to recognize it:

underscore 'MyHTML' #=> 'my_html'
camelize 'html' #=> 'HTML'
titleize 'html' #=> 'HTML'
acronym 'HTML'
Examples:

convert the acronym into a non-delimited single lowercase word when passed to +underscore+.
A camelized string that contains the acronym will maintain the acronym when titleized or humanized, and will
string that contains the acronym will retain the acronym when passed to `camelize`, `humanize`, or `titleize`.
Specifies a new acronym. An acronym must be specified as it will appear in a camelized string. An underscore

def clear(scope = :all)

clear :plurals
clear :all
Examples:

:singulars, :uncountables, :humans.
Give the scope as a symbol of the inflection type, the options are: :plurals,
Clears the loaded inflections within a given scope (default is :all). 
def clear(scope = :all)
  case scope
    when :all
      @plurals, @singulars, @uncountables, @humans = [], [], [], []

def human(rule, replacement)

human "legacy_col_person_name", "Name"
human /_cnt$/i, '\1_count'
Examples:

When a string is used, the human form should be specified as desired (example: 'The name', not 'the_name')
When using a regular expression based replacement, the normal humanize formatting is called after the replacement.
Specifies a humanized form of a string by a regular expression rule or by a string mapping. 
def human(rule, replacement)
  @humans.insert(0, [rule, replacement])
end

end

def irregular(singular, plural)

irregular 'person', 'people'
irregular 'octopus', 'octopi'
Examples:

for strings, not regular expressions. You simply pass the irregular in singular and plural form.
Specifies a new irregular that applies to both pluralization and singularization at the same time. This can only be used 
def irregular(singular, plural)
  @uncountables.delete(singular)
  @uncountables.delete(plural)
  if singular[0,1].upcase == plural[0,1].upcase
    plural(Regexp.new("(#{singular[0,1]})#{singular[1..-1]}$", "i"), '\1' + plural[1..-1])
    plural(Regexp.new("(#{plural[0,1]})#{plural[1..-1]}$", "i"), '\1' + plural[1..-1])
    singular(Regexp.new("(#{plural[0,1]})#{plural[1..-1]}$", "i"), '\1' + singular[1..-1])
  else
    plural(Regexp.new("#{singular[0,1].upcase}(?i)#{singular[1..-1]}$"), plural[0,1].upcase + plural[1..-1])
    plural(Regexp.new("#{singular[0,1].downcase}(?i)#{singular[1..-1]}$"), plural[0,1].downcase + plural[1..-1])
    plural(Regexp.new("#{plural[0,1].upcase}(?i)#{plural[1..-1]}$"), plural[0,1].upcase + plural[1..-1])
    plural(Regexp.new("#{plural[0,1].downcase}(?i)#{plural[1..-1]}$"), plural[0,1].downcase + plural[1..-1])
    singular(Regexp.new("#{plural[0,1].upcase}(?i)#{plural[1..-1]}$"), singular[0,1].upcase + singular[1..-1])
    singular(Regexp.new("#{plural[0,1].downcase}(?i)#{plural[1..-1]}$"), singular[0,1].downcase + singular[1..-1])
  end
end

def plural(rule, replacement)

The replacement should always be a string that may include references to the matched data from the rule.
Specifies a new pluralization rule and its replacement. The rule can either be a string or a regular expression. 
def plural(rule, replacement)
  @uncountables.delete(rule) if rule.is_a?(String)
  @uncountables.delete(replacement)
  @plurals.insert(0, [rule, replacement])
end

def singular(rule, replacement)

The replacement should always be a string that may include references to the matched data from the rule.
Specifies a new singularization rule and its replacement. The rule can either be a string or a regular expression. 
def singular(rule, replacement)
  @uncountables.delete(rule) if rule.is_a?(String)
  @uncountables.delete(replacement)
  @singulars.insert(0, [rule, replacement])
end

def uncountable(*words)

uncountable %w( money information rice )
uncountable "money", "information"
uncountable "money"
Examples:

Add uncountable words that shouldn't be attempted inflected. 
def uncountable(*words)
  (@uncountables << words).flatten!
