# jc.parsers.ls
jc - JSON CLI output utility `ls` and `vdir` command output parser

Options supported:
- `lbaR1`
- `--time-style=full-iso`

Note: The `-1`, `-l`, or `-b` option of `ls` should be used to correctly
parse filenames that include newline characters. Since `ls` does not encode
newlines in filenames when outputting to a pipe it will cause `jc` to see
multiple files instead of a single file if `-1`, `-l`, or `-b` is not used.
Alternatively, `vdir` can be used, which is the same as running `ls -lb`.

The `epoch` calculated timestamp field is naive. (i.e. based on the local
time of the system the parser is run on)

The `epoch_utc` calculated timestamp field is timezone-aware and is only
available if the timezone field is UTC.

Usage (cli):

    $ ls | jc --ls

    or

    $ jc ls

Usage (module):

    import jc
    result = jc.parse('ls', ls_command_output)

    or

    import jc.parsers.ls
    result = jc.parsers.ls.parse(ls_command_output)

Schema:

    [
      {
        "filename":     string,
        "flags":        string,
        "links":        integer,
        "parent":       string,
        "owner":        string,
        "group":        string,
        "size":         integer,
        "date":         string,
        "epoch":        integer,     # [0]
        "epoch_utc":    integer      # [1]
      }
    ]

    [0] naive timestamp if date field exists and can be converted.
    [1] timezone aware timestamp if date field is in UTC and can
        be converted.

Examples:

    $ ls /usr/bin | jc --ls -p
    [
      {
        "filename": "apropos"
      },
      {
        "filename": "arch"
      },
      ...
    ]

    $ ls -l /usr/bin | jc --ls -p
    [
      {
        "filename": "apropos",
        "link_to": "whatis",
        "flags": "lrwxrwxrwx.",
        "links": 1,
        "owner": "root",
        "group": "root",
        "size": 6,
        "date": "Aug 15 10:53"
      },
      {
        "filename": "ar",
        "flags": "-rwxr-xr-x.",
        "links": 1,
        "owner": "root",
        "group": "root",
        "size": 62744,
        "date": "Aug 8 16:14"
      },
      ...
    ]

    $ ls -l /usr/bin | jc --ls -p -r
    [
      {
        "filename": "apropos",
        "link_to": "whatis",
        "flags": "lrwxrwxrwx.",
        "links": "1",
        "owner": "root",
        "group": "root",
        "size": "6",
        "date": "Aug 15 10:53"
      },
      {
        "filename": "arch",
        "flags": "-rwxr-xr-x.",
        "links": "1",
        "owner": "root",
        "group": "root",
        "size": "33080",
        "date": "Aug 19 23:25"
