# jc.parsers.ls
jc - JSON CLI output utility `ls` and `vdir` command output parser
Options supported:
- `lbaR1`
- `--time-style=full-iso`
- `-h`: File sizes will be available in text form with `-r` but larger file sizes with human readable suffixes will be converted to `Null` in the default view since the parser attempts to convert this field to an integer.
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.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, # 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
}
