# jc.parsers.history
jc - JSON CLI output utility `history` command output parser

This parser will output a list of dictionaries each containing `line` and `command` keys. If you would like a simple dictionary output, then use the `-r` command-line option or the `raw=True` argument in the `parse()` function.

Usage (cli):

    $ history | jc --history

Usage (module):

    import jc.parsers.history
    result = jc.parsers.history.parse(history_command_output)

Compatibility:

    'linux', 'darwin', 'cygwin', 'aix', 'freebsd'

Examples:

    $ history | jc --history -p
    [
      {
        "line": 118,
        "command": "sleep 100"
      },
      {
        "line": 119,
        "command": "ls /bin"
      },
      {
        "line": 120,
        "command": "echo "hello""
      },
      {
        "line": 121,
        "command": "docker images"
      },
      ...
    ]

    $ history | jc --history -p -r
    {
      "118": "sleep 100",

      "120": "echo "hello"",
      "121": "docker images",
