For the benefit of other developers willing to control text width with `argparse`, using the lambda function let `mypy` fail with the following error: 541: error: Argument "formatter_class" to "ArgumentParser" has incompatible type "Callable[[Any], RawDescriptionHelpFormatter]"; expected "Type[HelpFormatter]" So I am reverting back to the following custom formatting class: class RawDescriptionHelpFormatterMaxTextWidth80(argparse.RawDescriptionHelpFormatter): """Set maximum text width = 80.""" def __init__(self, prog): width = min(80, shutil.get_terminal_size().columns - 2) argparse.RawDescriptionHelpFormatter.__init__(self, prog, width=width) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39809> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
