Netstring: A netstring parser and emitter

See the netstring specification for details.

Usage

require "netstring"

Dump:

netstring = Netstring.dump("xyz") # "3:xyz,"

Load:

string = Netstring.load("3:xyz,") # "xyz"

Get the netstring from which the string was loaded:

string.netstring # "3:xyz,"

Load concatenated netstrings:

netstring = "1:x,3:xyz,"
string1 = Netstring.load(netstring1) # "x"
offset = string1.netstring.size
netstring = netstring[offset..-1]
string2 = Netstring.load(netstring) # "xyz"

Load concatenated netstrings in a loop:

netstring = "1:x,3:xyz,"
strings = []
until netstring.empty?
  strings << Netstring.load(netstring)
  netstring = netstring[strings.last.netstring.size..-1]
end
