jc - JSON Convert nmcli command output parser

Supports the following nmcli subcommands:

Usage (cli):

$ nmcli device show lo | jc --nmcli

or

$ jc nmcli device show lo

Usage (module):

import jc
result = jc.parse('nmcli', nmcli_command_output)

Schema:

Because there are so many options, the schema is not strictly defined. Integer and Float value conversions are attempted and the original values are kept if they fail. If you don't want automatic conversion, then use the -r or raw=True option to disable it.

The structure is flat, for the most part, but there are a couple of "well-known" keys that are further parsed into objects for convenience. These are documented below.

[
  {
    "<key>":                  string/integer/float,   # [0]
    "dhcp4_option_x": {
      "name":                 string,
      "value":                string/integer/float,
    },
    "dhcp6_option_x": {
      "name":                 string,
      "value":                string/integer/float,
    },
    "ip4_route_x": {
      "dst":                  string,
      "nh":                   string,
      "mt":                   integer
    },
    "ip6_route_x": {
      "dst":                  string,
      "nh":                   string,
      "mt":                   integer,
      "table":                integer
    }
  }
]

[0] all values of `---` are converted to null
