Description:
 def echo(message=None, file=None, nl=True, err=False, color=None):
 """Prints a message plus a newline to the given file or stdout. On first sight, this looks like the print function, but it has improved support for handling Unicode and binary data that does not fail no matter how badly configured the system is. Primarily it means that you can print binary data as well as Unicode data on both 2.x and 3.x to the given file in the most appropriate way possible. This is a very carefree function as in that it will try its best to not fail. In addition to that, if `colorama`_ is installed, the echo function will also support clever handling of ANSI codes. Essentially it will then do the following: - add transparent handling of ANSI color codes on Windows. - hide ANSI codes automatically if the destination file is not a terminal. .. _colorama: http://pypi.python.org/pypi/colorama .. versionchanged:: 2.0 Starting with version 2.0 of Click, the echo function will work with colorama if it's installed. .. versionadded:: 3.0 The `err` parameter was added. .. versionchanged:: 4.0 Added the `color` flag. :param message: the message to print :param file: the file to write to (defaults to ``stdout``) :param err: if set to true the file defaults to ``stderr`` instead of ``stdout``. This is faster and easier than calling :func:`get_text_stderr` yourself. :param nl: if set to `True` (the default) a newline is printed afterwards. :param color: controls if the terminal supports ANSI colors or not. The default is autodetection. """
