When you hit a right paren, the cursor should move briefly to the left paren.

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>>� <KeyPress>� <ButtonPress>� <Key-Return>�<Key-BackSpace>c C s0 || _ |j| _|jj| j| j� d| _d| _d S )Nr )�editwin�textZbind�RESTORE_VIRTUAL_EVENT_NAME� restore_event�counter�is_restore_active)�selfr � r �7/opt/alt/python36/lib64/python3.6/idlelib/parenmatch.py�__init__( s zParenMatch.__init__c C sV t jddddd�| _t jdddddd �| _t jddd d d d �| _t jt j� 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 ]}| jj| 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 ]}| jj| 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�j� }| j|� 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 jd�}|tkrdS t| jd�}|j� s0dS |jt| d�}| j|� dS )z Handle user input of closer.z insert-1cNT)r �get�_openersr r Z is_in_coder. r/ )r r0 ZcloserZhpr1 r r r �paren_closed_eventS s z ParenMatch.paren_closed_eventc C sT |d kr | j r | jj� d S | j� | jj| j| j�| |� | jrH| j n| j � d S )N) r$ r r r* �tagfuncsr3 r" �create_tag_expressionr# �set_timeout_last�set_timeout_none)r r1 r r r r/ ` s z ParenMatch.finish_paren_eventNc C s& | j jd� | j� | jd7 _dS )z Remove effect of doing match.�parenr!
