If this is ``None``, the prompt will not be changed. This will be formatted with the new and continuation prompts as positional parameters, so you can use ``{}`` style formatting to insert them into the command. :param str new_prompt: The more unique prompt to expect after the change. :param str extra_init_cmd: Commands to do extra initialisation, such as disabling pagers.

Trailing newlines are not needed. This should be a complete block of input that will trigger execution; if a continuation prompt is found after sending input, :exc:`ValueError` will be raised. :param int timeout: How long to wait for the next prompt. -1 means the default from the :class:`pexpect.spawn` object (default 30 seconds). None means to wait indefinitely. :param bool async_: On Python 3.4, or Python 3.3 with asyncio installed, passing ``async_=True`` will make this return an :mod:`asyncio` Future, which you can yield from to get the same result that this method would normally give directly. � � zNo command was given� )�repl_run_command_asyncr N)r! z2Continuation prompt found - input was incomplete: )� splitlines�endswith�append� ValueError�_asyncr' r r r �before�kill�signal�SIGINT�join)r �commandr! r" �cmdlinesr' �res�liner r r r D s* �zREPLWrapper.run_command)r F) �__name__� __module__� __qualname__�__doc__�PEXPECT_PROMPT�PEXPECT_CONTINUATION_PROMPTr r r r r r r r r s � r �pythonc C s t | dd�S )z>Start a Python shell and return a :class:`REPLWrapper` object.z>>> z(import sys; sys.ps1={0!r}; sys.ps2={1!r})r )r2 r r r r< o s �bashc C s� t j�t j�t�d�}tj| d|gddd�}tdd� d tdd� }tdd� d tdd� }d � ||�}t |d |d d �S ) z<Start a bash shell and return a :class:`REPLWrapper` object.z bashrc.shz--rcfileFr r N� z\[\]z%PS1='{0}' PS2='{1}' PROMPT_COMMAND=''z\$zexport PAGER=cat)r ) �os�pathr1 �dirname�__file__r r r: r; r r )r2 �bashrcr �ps1�ps2r r r r r= s s � �)r< )r= )r9 �os.pathr? r/ �sysr � version_info�PY3�strr r: r; �objectr r< r= r r r r �<module> s ^
