LTSV: A Parser / Dumper for Labelled Tab-Separated Values (LTSV)


Add this line to your application's Gemfile:

gem 'ltsv'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ltsv


At first, you should require ltsv:

require 'ltsv'

In addition, if you manage gems with bundler, you should add the statement below into your Gemfile:

gem 'ltsv'

parsing LTSV

# parse string
string = "label1:value1\tlabel2:value2"
values = LTSV.parse(string) # => [{:label1 => "value1", :label2 => "value2"}]

# parse via stream
# content: as below
# label1_1:value1_1\tlabel1_2:value1_2
# label2_1:value2_1\tlabel2_2:value2_2
stream ="some_file.ltsv", "r")
values = LTSV.parse(stream)
# => [{:label1_1 => "value1_2", :label1_2 => "value1_2"},
#     {:label2_1 => "value2_2", :label2_2 => "value2_2"}]

loading LTSV file

# load via path
values = LTSV.load("some_path.ltsv")

# load via stream
stream ="some_file.ltsv", "r")
values = LTSV.load(stream) # => same as LTSV.parse(stream)

dumping into LTSV

value = {label1: "value1", label2: "value2"}
dumped = LTSV.dump(value) # => "label1:value1\tlabel2:value2"

Dumped objects should respond to :to_hash.
