jc - JSON Convert Proc file output parser

This parser automatically identifies the Proc file and calls the corresponding parser to perform the parsing.

Magic syntax for converting /proc files is also supported by running jc /proc/<path to file>. Any jc options must be specified before the /proc path. The magic syntax supports "slurping" multiple files as input. When multiple files are selected (e.g. jc /proc/*/stat) all of the output will be wrapped inside an array. Also, a _file field will be included in the output which helps correlate the input and output. The --meta-out option can also be used to list the /proc input files for correlation with the output list.

Specific Proc file parsers can also be called directly, if desired, and have a naming convention of proc-<name> (cli) or proc_<name> (module). To see a list of Proc file parsers, use jc -hh or jc -a.

Usage (cli):

$ cat /proc/meminfo | jc --proc

or

$ jc /proc/meminfo

or

$ cat /proc/meminfo | jc --proc-memifno

Usage (module):

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

Schema:

See the specific Proc parser for the schema:

$ jc --help --proc-<name>

For example:

$ jc --help --proc-meminfo

Specific Proc file parser names can be found with jc -hh or jc -a.

Schemas can also be found online at:
