Something like yaml? If I understand your request this is pretty close:

require 'yaml'

# arbitrary value (in this case a hash)
hash = { :foo => :bar, 'answer' => 42 }

# save it to a file
File.open( 'test.yaml', 'w') { |out| out.puts hash.to_yaml }

# read it back from a file
new_hash = YAML::load( File.open( 'test.yaml' ))

# show that they are equal
p hash
p new_hash



If you are curious the file is a readable text file:

answer: 42
:foo: :bar
