jc - JSON Convert ping command output streaming parser

This streaming parser outputs JSON Lines (cli) or returns an Iterable of Dictionaries (module)

Supports ping and ping6 output.

Usage (cli):

$ ping | jc --ping-s

Note: When piping jc converted ping output to other processes it may appear the output is hanging due to the OS pipe buffers. This is because ping output is too small to quickly fill up the buffer. Use the -u option to unbuffer the jc output if you would like immediate output. See the readme for more information.

Usage (module):

import jc

result = jc.parse('ping_s', ping_command_output.splitlines())
for item in result:
    # do something
