This assumes that Windows sends us the right vt100 escape sequences and we parse those with our vt100 parser. (Using this instead of `ConsoleInputReader` results in the "data" attribute from the `KeyPress` instances to be more correct in edge cases, because this responds to for instance the terminal being in application cursor keys mode.) r- r. c sl d � _ g � _t� fdd��� _� tj�� r@ttj � t ��� _ n(t �dt jt jB �� _ tt�� j ��� _ d S )Nc s � j �| �S r0 )�_bufferr� )r� r3 r5 r6 �<lambda>M r� z2Vt100ConsoleInputReader.__init__.<locals>.<lambda>r� )r� r� r$ � _vt100_parserrS r> r� r r r� r� r r8 r� r� r� r� r� r� r3 r5 r3 r6 r7 H s � z Vt100ConsoleInputReader.__init__c C s | j durt�| j � dS r� r� r3 r5 r5 r6 rW Y s z Vt100ConsoleInputReader.closer� c C sx d}t d�}t| }|� }t| jgdd�s.g S tj�| jt|�|t|�� | �||�D ]}| j � |� qV| j }g | _ |S )r� r� r r� ) r r r r8 r r� r� r r� r� �feedr� )r4 r� rL r� r� Zkey_datar� r5 r5 r6 rL ^ s �z Vt100ConsoleInputReader.readr r� z Iterator[str]r� c c s^ t |j�D ]N}|| }|jtv r t|jt|j �}t|t�r |jr |j j }|dkr |V q dS )r� r� N) r� r� r� r r� r� r� r r� r� r� )r4 rL r� r� r� r� r� r5 r5 r6 r� � s z!Vt100ConsoleInputReader._get_keysN)r9 r: r; r< r7 rW rL r� r5 r5 r5 r6 rB ; s %rB c @ s@ e Zd ZdZdd�dd�Zdddd�d d �Zdd d �d d�ZdS )r1 a� Utility to keep track of which handles are connectod to which callbacks. `add_win32_handle` starts a tiny event loop in another thread which waits for the Win32 handle to become ready. When this happens, the callback will be called in the current asyncio event loop using `call_soon_threadsafe`. `remove_win32_handle` will stop this tiny event loop. NOTE: We use this technique, so that we don't have to use the `ProactorEventLoop` on Windows and we can wait for things like stdin in a `SelectorEventLoop`. This is important, because our inputhook mechanism (used by IPython), only works with the `SelectorEventLoop`. r- r. c C s i | _ i | _d S r0 )�_handle_callbacks�_remove_eventsr3 r5 r5 r6 r7 � s z_Win32Handles.__init__r rF )r8 �callbackr/ c s~ �j }|du rtd��| ��� t� �� | j|< t� ��| j|< dd�� ��fdd� �dd�����fdd� �t��d � dS ) z7 Add a Win32 handle to the event loop.
