Dumping the value given into a new String. Each special character will be escaped with backslash(‘'), and the expression should be contained in a single line.
value: a target to dump. It should respond to :to_hash.
A LTSV String
# File lib/ltsv.rb, line 71 def dump(value) raise ArgumentError, "dump should take an argument of hash" unless value.respond_to? :to_hash hash = value.to_hash hash.inject('') do |s, kv| s << "\t" if s.bytesize > 0 (k, v) = kv value = escape v s << k.to_s << ':' << value end end
Parsing the content of the given stream or path. If you specified a stream as the first argument, this method behaves as same as load.
io_or_string: a target to parse. Possible values are: String, IO. If you give the string value, it stands the path of the file to parse. If you give the IO value, it stands the stream which provides the contents to parse. Note : If you give the IO value, this method behaves like parse.
symbolize_keys : Whether the label will be available as symbol or not. Default value is true.
encoding : The encoding of the stream given as the first argument. Default value: Encoding.default_external
An Array of Hash : Each hash stands for a line of the io or the file.
