routeparser: A route command output text parser

It provides:

• Reading text output of routes into Python objects
• Simple identification of routes that match hosts or networks

Installation:

• pip install routeparser

Usage:

• example (where netstat_rn.txt is full output from 'netstat -rn' on Linux):

  import routeparser
  
  # read lines from a file
  with open('netstat_rn.txt', 'r') as file_handle:
      lines = file_handle.readlines()
  
  # You can just get objects representing the routes if you wish:
  routes = routeparser.Route.from_linux_netstat_lines(lines)
  
  # These have attributes such as gateway, interface and network.
  # Some example values as in-line comments:
  routes[0].gateway  # ipaddress.IPv4Address('192.168.1.1')
  routes[0].interface  # 'eth0'
  routes[0].network  # ipaddress.IPv4Network('10.10.0.0/16')
  
  # Route objects support membership testing:
  '10.10.10.1' in routes[0]  # would return True, given the above example route
  
  # You can get a RoutingTable object from the lines:
  table = routeparser.RoutingTable.from_linux_netstat_lines(lines)
  
  # which you can then use to check for specific route matches:
  table.match('10.10.10.1')  # would result in a matching Route object, if any
  
  # It supports string or Address/Network objects from the ipaddress module:
  import ipaddress
  table.match(ipaddress.ip_network('10.10.10.0/24'))
  
  # You can even get a list of all matching routes:
  table.matches('10.10.10.10')
  
  # Currently supported outputs and associated methods (for Route and RoutingTable)
  # Windows:
  #  - 'route print': from_windows_route_print_lines
  # Linux:
  #  - 'ip route': from_ip_route_lines
  #  - 'netstat -r[nv]': from_linux_netstat_lines
  #  - 'route [-n]': from_linux_route_lines
