    def plain(self):
        '''is plain mode active?

        Plain mode means that all configuration variables which affect the
        behavior and output of Mercurial should be ignored. Additionally, the
        output should be stable, reproducible and suitable for use in scripts or
        applications.

        The only way to trigger plain mode is by setting the `HGPLAIN'
        environment variable.

    def interactive(self):
        '''is interactive input allowed?

        An interactive session is a session where input can be reasonably read
        from `sys.stdin'. If this function returns false, any attempt to read
        from stdin should fail with an error, unless a sensible default has been
        specified.

        Interactiveness is triggered by the value of the `ui.interactive'
        configuration variable or - if it is unset - when `sys.stdin' points
        to a terminal device.

        This function refers to input only; for output, see `ui.formatted()'.

    def formatted(self):
        '''should formatted output be used?

        It is often desirable to format the output to suite the output medium.
        Examples of this are truncating long lines or colorizing messages.
        However, this is not often not desirable when piping output into other
        utilities, e.g. `grep'.

        Formatted output is triggered by the value of the `ui.formatted'
        configuration variable or - if it is unset - when `sys.stdout' points
        to a terminal device. Please note that `ui.formatted' should be
        considered an implementation detail; it is not intended for use outside
        Mercurial or its extensions.

        This function refers to output only; for input, see `ui.interactive()'.
        This function always returns false when in plain mode, see `ui.plain()'.
