When you hit a right paren, the cursor should move briefly to the left paren. Paren here is used generically; the matching applies to parentheses, square brackets, and curly braces. � )� HyperParser)�idleConf�(�[�{)�)�]�}�d c @ s� e Zd ZdZdZdZdd� Zedd� �Zdd � Z d d � Z d d � Z dd� Z dd� Z d"dd�Zdd� Zdd� Zdd� Zdd � Zeeeed �Zd d � Zd d!� ZdS )#� ParenMatcha' Highlight matching openers and closers, (), [], and {}. There are three supported styles of paren matching. When a right paren (opener) is typed: opener -- highlight the matching left paren (closer); parens -- highlight the left and right parens (opener and closer); expression -- highlight the entire expression from opener to closer. (For back compatibility, 'default' is a synonym for 'opener'). Flash-delay is the maximum milliseconds the highlighting remains. Any cursor movement (key press or click) before that removes the highlight. If flash-delay is 0, there is no maximum. TODO: - Augment bell() with mismatch warning in status window. - Highlight when cursor is moved to the right of a closer. This might be too expensive to check. z <<parenmatch-check-restore>>)z <KeyPress>z <ButtonPress>z <Key-Return>z<Key-BackSpace>c C s0 || _ |j| _|j�| j| j� d| _d| _d S )Nr )�editwin�textZbind�RESTORE_VIRTUAL_EVENT_NAME� restore_event�counter�is_restore_active)�selfr � r �7/opt/alt/python37/lib64/python3.7/idlelib/parenmatch.py�__init__( s zParenMatch.__init__c C sV t jddddd�| _t jdddddd �| _t jddd d d d �| _t �t �� d �| _d S )N� extensionsr Zstyle�opener)�defaultz flash-delay�inti� )�typer �bell�bool� Zhilite)r Z GetOption�STYLE� FLASH_DELAY�BELLZ GetHighlightZ CurrentTheme� HILITE_CONFIG)�clsr r r �reload3 s zParenMatch.reloadc C s0 | j s,x | jD ]}| j�| j|� qW d| _ dS )z5Activate mechanism to restore text from highlighting.TN)r �RESTORE_SEQUENCESr Z event_addr )r �seqr r r �activate_restore> s zParenMatch.activate_restorec C s0 | j r,x | jD ]}| j�| j|� qW d| _ dS )z Remove restore event bindings.FN)r r$ r Z event_deleter )r r% r r r �deactivate_restoreE s z ParenMatch.deactivate_restorec C s t | jd��� }| �|� dS )zAHandle editor 'show surrounding parens' event (menu or shortcut).�insert�break)r r �get_surrounding_brackets�finish_paren_event)r �event�indicesr r r �flash_paren_eventL s z ParenMatch.flash_paren_eventc C sN | j �d�}|tkrdS t| jd�}|�� s0dS |�t| d�}| �|� dS )z Handle user input of closer.z insert-1cNT)r �get�_openersr r Z is_in_coder* r+ )r r, ZcloserZhpr- r r r �paren_closed_eventS s z ParenMatch.paren_closed_eventc C sT |d kr | j r | j�� d S | �� | j�| j| j�| |� | jrH| j n| j � d S )N) r r r r& �tagfuncsr/ r �create_tag_expressionr �set_timeout_last�set_timeout_none)r r- r r r r+ ` s z ParenMatch.finish_paren_eventNc C s& | j �d� | �� | jd7 _dS )z Remove effect of doing match.�parenr N)r Z tag_deleter' r )r r, r r r r k s zParenMatch.restore_eventc C s || j kr| �� d S )N)r r )r Z timer_countr r r �handle_restore_timerq s z ParenMatch.handle_restore_timerc C s& | j �d|d � | j �d| j� dS )z'Highlight the single paren that matchesr6 r N)r �tag_add� tag_configr! )r r- r r r �create_tag_openerx s z ParenMatch.create_tag_openerc C sb | j �|d �dkr"|d d }n|d }| j �d|d |d d |d |� | j �d| j� dS )z#Highlight the left and right parensr )r r r z+1cr6 r z-1cN)r r/ r8 r9 r! )r r- � rightindexr r r �create_tag_parens} s $z ParenMatch.create_tag_parensc C sR | j �|d �dkr"|d d }n|d }| j �d|d |� | j �d| j� dS )z Highlight the entire expressionr )r r r z+1cr6 r N)r r/ r8 r9 r! )r r- r; r r r r3 � s z ParenMatch.create_tag_expression)r r ZparensZ expressionc C s> | j d7 _ | | j | j�d�fdd�}| jj�t||� dS )zSHighlight will remain until user input turns it off or the insert has movedr r( c S s2 ||j �d�kr |�|� n|jj�t| | � d S )Nr( )r �indexr7 r � text_frame�after� CHECK_DELAY)�callmer �cr= r r r rA � s z+ParenMatch.set_timeout_none.<locals>.callmeN)r r r= r r> r? r@ )r rA r r r r5 � s zParenMatch.set_timeout_nonec C s0 | j d7 _ | jj�| j| | j fdd�� dS )zFThe last highlight created will be removed after FLASH_DELAY millisecsr c S s | � |�S )N)r7 )r rB r r r �<lambda>� � z-ParenMatch.set_timeout_last.<locals>.<lambda>N)r r r> r? r )r r r r r4 � s zParenMatch.set_timeout_last)N)�__name__� __module__� __qualname__�__doc__r r$ r � classmethodr# r& r' r. r1 r+ r r7 r: r< r3 r2 r5 r4 r r r r r s* r �__main__)�mainz!idlelib.idle_test.test_parenmatch� )� verbosityN) rH Zidlelib.hyperparserr Zidlelib.configr r0 r@ r r# rE ZunittestrK r r r r �<module> s &
