jc - JSON Convert /proc/vmallocinfo file parser

This parser will attempt to convert number values to integers. If that is not desired, please use the --raw option (cli) or raw=True argument (module).

Usage (cli):

$ cat /proc/vmallocinfo | jc --proc

or

$ jc /proc/vmallocinfo

or

$ cat /proc/vmallocinfo | jc --proc-vmallocinfo

Usage (module):

import jc
result = jc.parse('proc', proc_vmallocinfo_file)

or

import jc
result = jc.parse('proc_vmallocinfo', proc_vmallocinfo_file)

Schema:

[
  {
    "start":                  string,
    "end":                    string,
    "size":                   integer,
    "caller":                 string,
    "options": [
                              string
    ],
    "phys":                   string
    "pages":                  integer,
    "N<id>":                  integer
