blank?()

An Pathname is blank if it’s empty:

Pathname.new("").blank?      # => true
Pathname.new(" ").blank?     # => false
Pathname.new("test").blank?  # => false

@return [true, false]

def blank?
  to_s.empty?
end

existence()

Returns the receiver if the named file exists; otherwise, returns nil. pathname.existence is equivalent to:

pathname.exist? ? pathname : nil

For example, this:

content = pathname.read if pathname.exist?

becomes:

content = pathname.existence&.read

@return [Pathname]
