Console error when running in IDLE on Windows

• parglare version: 0.8.0
• Python version: 3.7.0
• Operating System: Windows 10 x64

When I run the introductory example in IDLE, I get the following error, which shouldn't happen:

>>> parser = Parser(g, debug=True, actions=actions)

Traceback (most recent call last):
  File "<pyshell#27>", line 1, in <module>
    parser = Parser(g, debug=True, actions=actions)
  File "...\parglare\parser.py", line 90, in __init__
    self.print_debug()
  File "...\parglare\parser.py", line 123, in print_debug
    self.table.print_debug()
  File "...\parglare\tables\__init__.py", line 468, in print_debug
    a_print("*** STATES ***", new_line=True)
  File "...\parglare\termui.py", line 64, in a_print
    styled_print(header, content, level, new_line, S_ATTENTION)
  File "...\parglare\termui.py", line 56, in styled_print
    prints(style(header, content, level, new_line, header_style, width))
  File "...\parglare\termui.py", line 17, in prints
    click.echo(style(message, s), color=colors)
  File "...\click\utils.py", line 217, in echo
    file = _default_text_stdout()
  File "...\click\_compat.py", line 621, in func
    rv = wrapper_func()
  File "...\click\_compat.py", line 385, in get_text_stdout
    rv = _get_windows_console_stream(sys.stdout, encoding, errors)
  File "...\click\_winconsole.py", line 261, in _get_windows_console_stream
    func = _stream_factories.get(f.fileno())
io.UnsupportedOperation: fileno

It seems that the issue occurs because the output stream isn't an actual console. It doesn't happen in an actual console.

I can't be sure since I don't use IDLE or Win. But from the stack trace I guess you are right. It seems that the problem is that its not a proper console required by the click library.

Thanks for the report. Good to know that the problem exists.
