# Blob is a Rails-specific wrapper around Gitlab::Git::Blob objects
class Blob < SimpleDelegator
# Wrap a Gitlab::Git::Blob object, or return nil when given nil
#
# This method prevents the decorated object from evaluating to "truthy" when
# given a nil value. For example:
#
# blob = Blob.new(nil)
# puts "truthy" if blob # => "truthy"
#
# blob = Blob.decorate(nil)
# puts "truthy" if blob # No output
def self.decorate(blob)
