# jc.parsers.ls_s
jc - JSON CLI output utility `ls` and `vdir` command output streaming 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-s

Usage (module):

    import jc.parsers.ls_s
    result = jc.parsers.ls_s.parse(ls_command_output)    # result is an iterable object
    for item in result:
        # do something

Schema:

    {
      "filename":       string,
      "flags":          string,
      "links":          integer,
      "parent":         string,      # not yet implemented

      "group":          string,
      "size":           integer,
      "date":           string,
      "epoch":          integer,     # naive timestamp if date field exists and can be converted
      "epoch_utc":      integer,     # timezone aware timestamp if date field is in UTC and can be converted
      "_meta":
        {
          "success":    booean,    # true if successfully parsed, false if error
          "error_msg":  string,    # exists if "success" is false
          "line":       string     # exists if "success" is false
        }
    }

    $ ls -l /usr/bin | jc --ls-s
