This only works in single-threaded systems without any concurrency as it changes the global interpreter state. :param charset: the character set for the input and output data. :param env: a dictionary with environment variables for overriding. :param echo_stdin: if this is set to `True`, then reading from stdin writes to stdout. This is useful for showing examples in some circumstances. Note that regular prompts will automatically echo the input. :param mix_stderr: if this is set to `False`, then stdout and stderr are preserved as independent streams. This is useful for Unix-philosophy apps that have predictable stdout and noisy stderr, such that each may be measured independently �utf-8NFTrJ �env� echo_stdin� mix_stderrr c C s || _ |pi | _|| _|| _d S r )rJ rr rs rt )r rJ rr rs rt r r r r � s zCliRunner.__init__�clir c C s |j pdS )z�Given a command object it will return the default program name for it.

This sets up stdin with the given input data and `os.environ` with the overrides from the given dictionary. This also rebinds some internals in Click to be mocked (like the prompt functionality). This is automatically done in the :meth:`invoke` method. :param input: the input stream to put into sys.stdin. :param env: the environment overrides as dictionary. :param color: whether the output should contain color codes. The application can still override this explicitly. .. versionchanged:: 8.0 ``stderr`` is opened with ``errors="backslashreplace"`` instead of the default ``"strict"``. .. versionchanged:: 4.0 Added the ``color`` parameter.

The arguments are forwarded directly to the command line script, the `extra` keyword arguments are passed to the :meth:`~clickpkg.Command.main` function of the command. This returns a :class:`Result` object. :param cli: the command to invoke :param args: the arguments to invoke. It may be given as an iterable or a string. When given as string it will be interpreted as a Unix shell command. More details at :func:`shlex.split`. :param input: the input data for `sys.stdin`. :param env: the environment overrides. :param catch_exceptions: Whether to catch any other exceptions than ``SystemExit``. :param extra: the keyword arguments to pass to :meth:`main`. :param color: whether the output should contain color codes. The application can still override this explicitly. .. versionchanged:: 8.0 The result object has the ``return_value`` attribute with the value returned from the invoked command. .. versionchanged:: 4.0 Added the ``color`` parameter. .. versionchanged:: 3.0 Added the ``catch_exceptions`` parameter. .. versionchanged:: 3.0 The result object has the ``exc_info`` attribute with the traceback if available.
