Subject: | --json and --format=json? |
Currently these options don't make hr generating json:
$ /opt/perl-5.22.0/bin/hr --json | json_pp
malformed JSON string, neither array, object, number, string or atom, at character offset 0 (before "====================...") at /usr/bin/json_pp line 44
And actually I can't think of a valid use case for such an option, so it's probably better to simplify the command and remove these options.
