#ctry(*args) ⇒ Object

Chained try

Allows writing

str.ctry(:mb_chars, :downcase, :dasherize)

instead of

str.try(:mb_chars).try(:downcase).try(:dasherize)

Only works for methods that dont have any arguments

def ctry(*args)
  first, *rest = args
  if rest.any?
    self.try(first).ctry(*rest)
  else
    self.try(first)
  end
end

#identity ⇒ Object

Returns self. If given a block, it works a lot like Object#tap

Examples

[1,2,3,5,7].consecutive_by(:identity) 
=> [[1, 2, 3], [5], [7]]
