ActiveSupport.Inflector.titleize
ruby
def titleize(word) # negative lookbehind doesn't work in Firefox / Safari # humanize(underscore(word)).gsub(/\b(?<!['’`])[a-z]/) { |match| match.capitalize } humanized = humanize(underscore(word)) humanized.reverse.gsub(/[a-z](?!['’`])\b/) { |match| match.capitalize }.reverse end
Capitalizes all the words and replaces some characters in the string to create a nicer looking title. +titleize+ is meant for creating pretty output. It is not used in the Rails internals. +titleize+ is also aliased as +titlecase+. titleize('man from the boondocks') # => "Man From The Boondocks" titleize('x-men: the last stand') # => "X Men: The Last Stand" titleize('TheManWithoutAPast') # => "The Man Without A Past" titleize('raiders_of_the_lost_ark') # => "Raiders Of The Lost Ark"

Defines new method wrappers for Windows API function call: - Defines method with original (CamelCase) API function name and original signature (matches MSDN description) - Defines method with snake_case name (converted from CamelCase function name) with enhanced API signature When the defined wrapper method is called, it checks the argument count, executes underlying API function call and (optionally) transforms the result before returning it. If block is attached to method invocation, raw result is yielded to this block before final transformations - Defines aliases for enhanced method with more Rubyesque names for getters, setters and tests: GetWindowText -> window_test, SetWindowText -> window_text=, IsZoomed -> zoomed? You may modify default behavior of defined method by providing optional &define_block to def_api. If you do so, instead of directly calling API function, defined method just yields callable api object, arguments and (optional) runtime block to your &define_block and returns result coming out of it. So, &define_block should define all the behavior of defined method. You can use define_block to: - Change original signature of API function, provide argument defaults, check argument types - Pack arguments into strings for [in] or [in/out] parameters that expect a pointer - Allocate string buffers for pointers required by API functions [out] parameters - Unpack [out] and [in/out] parameters returned as pointers - Explicitly return results of API call that are returned in [out] and [in/out] parameters - Convert attached runtime blocks into callback functions and stuff them into [in] callback parameters Accepts following options: :dll:: Use this dll instead of default 'user32' :rename:: Use this name instead of standard (conventional) function name :alias(es):: Provides additional alias(es) for defined method :boolean:: Forces method to return true/false instead of nonzero/zero :zeronil:: Forces method to return nil if function result is zero

The ImageList class supports the Magick::Image class methods by simply sending the method to the current image. If the method isn't explicitly supported, send it to the current image in the array. If there are no images, send it up the line. Catch a NameError and emit a useful message.
