All values have a granularity of 0.1s, ie. any value between 0.15 and 0.05 will be treated as 0.1 and any value less than 0.05 will be treated as 0. The maximum timeout value for this module is 25.5 seconds. max_wait -- amount of time in seconds to wait for input when there is no input pending, wait forever if None complete_wait -- amount of time in seconds to wait when get_input detects an incomplete escape sequence at the end of the available input resize_wait -- amount of time in seconds to wait for more input after receiving two screen resize requests in a row to stop urwid from consuming 100% cpu during a gradual window resize operation c S s | d u rd S t | d d �S )Ng�������?rE )�int)r r) r) r* �convert_to_tenths� s z4Screen.set_input_timeouts.<locals>.convert_to_tenthsN)� max_tenths�complete_tenths� resize_tenths)r& �max_wait� complete_wait� resize_waitrq r) r) r* r! � s zScreen.set_input_timeoutsFc C s� | j sJ �| �| j�\}}|dgkrE| jrE | �| j�\}}||7 }|s0| �| j�\}}||7 }|dgkr6nq|dd� dgkrE|�d� |dgkrNd| _n| jdkrY|sYd| _nd| _|rb||fS |S )a� Return pending input as a list. raw_keys -- return raw keycodes as well as translated versions This function will immediately return all the input since the last time it was called. If there is no input pending it will wait before returning an empty list. The wait time may be configured with the set_input_timeouts function. If raw_keys is False (default) this function will return a list of keys pressed. If raw_keys is True this function will return a ( keys pressed, raw keycodes ) tuple instead. Examples of keys returned: * ASCII printable characters: " ", "a", "0", "A", "-", "/" * ASCII control characters: "tab", "enter" * Escape sequences: "up", "page up", "home", "insert", "f1" * Key combinations: "shift f1", "meta a", "ctrl b" * Window events: "window resize" When a narrow encoding is not enabled: * "Extended ASCII" characters: "\xa1", "\xb2", "\xfe" When a wide encoding is enabled: * Double-byte characters: "\xa1\xea", "\xb2\xd4" When utf8 encoding is enabled: * Unicode characters: u"\u00a5", u'\u253c" Examples of mouse events returned: * Mouse button press: ('mouse press', 1, 15, 13), ('meta mouse press', 2, 17, 23) * Mouse button release: ('mouse release', 0, 18, 13), ('ctrl mouse release', 0, 17, 23) � window resizeTr N� r r )�_started� _get_inputrr r rt �append)r& �raw_keys�keys�raw�raw2r) r) r* � get_input� s0 )� � zScreen.get_inputc C s> t �� | �|�}d}g }g }|dkr7|�|� |tkr d}n|tkr*|| �� 7 }n|�|� | �� }|dksg }z|rJt� |d�\}}||7 }|s<W nH tj y� | �| j �}|dkr�|�|� |tkrid}n|tkrt|| �� 7 }n|�|� | �� }|dks]|r�t� |d�\}}||7 }|s�Y nw |r�|�d� ||fS )NFr Trx ) r, �doupdaterm r| � KEY_RESIZE� KEY_MOUSE�_encode_mouse_eventrh r �process_keyqueue�MoreInputRequiredrs )r& rl �key�resizer r~ � processed�runr) r) r* r{ 6 sR � �� � ��� zScreen._get_inputc s� | j }}t�� \}��}}d�|tj@ r�dO �|tj@ r"�dO �|tj@ r+�dO �g � � ���fdd�}|tj@ rI|d@ dkrI|d� |dO }|tj@ r\|d@ dkr\|d� |dO }|tj@ ro|d@ dkro|d� |dO }|tj @ r�|d@ dkr�|d � |dO }|tj @ r�|d@ r�|dt j � |d M }|tj @ r�|d@ r�|dt j � |d M }|tj@ r�|d@ r�|dt j � |d M }|tj@ r�|d@ r�|d t j � |d M }|tj@ r�|dt j � |tj@ r�|dt j � |tj@ r�|dt j � |tj@ �r|d t j � |tj@ �r|dt jd � |tj@ �r!|dt jd � |tj@ �r0|dt jd � |tj@ �r?|d t jd � || _ � S )Nr � rD � c s6 | �O } � � dtd�td�| d �d �d g� d S )N� �[�M� �! )�extendr )�b��l�modrc �yr) r* � append_buttonq s .z1Screen._encode_mouse_event.<locals>.append_buttonr ry �@ ���������i����)r" r, �getmouser> r? r@ r. r0 r2 r4 r/ r �MOUSE_RELEASE_FLAGr1 r3 r5 r6 �MOUSE_MULTIPLE_CLICK_FLAGr8 r: r< r7 r9 r; r= )r& �last�next�id�z�bstater� r) r� r* r� f sd zScreen._encode_mouse_eventc C s4 t �� | j�d� t �d� | j�� }t �� |S )Nr �d )r, rW r rj rQ �getstrrO �r& �strr) r) r* � _dbg_instr� s zScreen._dbg_instrc C s. | j �� | j �|� | j �� | �d� d S rn )r �clrtoeol�addstrrf rX r� r) r) r* �_dbg_out� s zScreen._dbg_outc C s | � |� | �� S rd )r� r� )r& �questionr) r) r* � _dbg_query� s zScreen._dbg_queryc C s | j �� d S rd )r rf r% r) r) r* � _dbg_refresh� s zScreen._dbg_refreshc C s | j �� \}}||fS )z7Return the terminal dimensions (num columns, num rows).)r �getmaxyx)r& �rows�colsr) r) r* � get_cols_rows� s zScreen.get_cols_rowsc C s� |d u r | j �d� d S t|t�s | j�|tdd�f�}|d }| jrL|jr5|jdkr1|jd }n|j}nd}|j r>|j }nd}t � |d d | �}nd}|j rV|t jO }|jr^|t jO }|jrf|t jO }|jrn|t jO }| j �|� d S )Nr r rD r[ )r �attrset� isinstancer �_palette�getr �foreground_basic�foreground_number�background_basic�background_numberr, � color_pair�bold�A_BOLD�standout� A_STANDOUT� underline� A_UNDERLINE�blink�A_BLINK)r& �a�pr_ r` �attrr) r) r* �_setattr� s4 zScreen._setattrc C s� | j sJ �|\}}|�� |ksJ d��d}|�� D ]�}|d7 }z | j�|d� W n tjy4 Y dS w d}d}d} |D ]�\} } } | dkrR| �t�} t | t �sRJ �|sX|| kr_| � | � | }z;| dv rzt t | ��D ]} | j�d t| | � � qjn | du s�J �tr�t | t �s�J �| j�| �d �� n| j�| � W n tjy� ||d kr�| t |�d kr�nY dS Y nw | d7 } q=q|jdur�|j\}}| �d� z | j�||� W n tjy� Y n w | �d� | j�dd� | j�� || _dS ) z"Paint screen with rendered canvas.z'canvas size and passed size don't matchr r r NT�U)�0r� i @ �utf-8)rz r� �contentr �moverL rM � translater r� r r� �range�len�addchr r r� �decode�cursorrX rf �keep_cache_alive_link)r& �size�rr� r� r� �row�first�lasta�nrr� �cs�seg�irc r) r) r* � draw_screen� sh � � � �� � � zScreen.draw_screenc C s | j �� dS )zh Force the screen to be completely repainted on the next call to draw_screen().
