Sample from the README does not work

[retorquere]

I've just copied this from the README:

README script

from compact_json import Formatter, EolStyle

formatter = Formatter()
formatter.indent_spaces = 2
formatter.max_inline_complexity = 10
formatter.json_eol_style = EolStyle.LF

# Format the JSON contents:
with open("input.json", "r") as f:
    obj = json.load(f)
    json_string = formatter.serialize(obj)
    print(json_string)

# Create a new JSON file with formatted JSON contents:
with open("input.json", "r") as f:
    obj = json.load(f)

formatter.dump(obj, output_file="output.json", newline_at_eof=True)

Minor details is that it should import json, but even when I do that, I get

AttributeError: 'Formatter' object has no attribute 'dump'

Finally updated. Thanks for the issue report.
