Each menu selection or shortcut key selection replaces the word with a different word with the same prefix. The search for matches begins before the target and moves toward the top of the editor. It then starts after the cursor and moves down. It then returns to the original word and the cycle starts again. Changing the current text line or leaving the cursor in a different place before requesting the next selection causes AutoExpand to reset its state. There is only one instance of Autoexpand. � Nc @ s< e Zd Zejej d Zdd� Zdd� Zdd� Z dd � Z d S ) � AutoExpand�_c C s |j | _ | j j| _d | _d S )N)�text�bell�state)�selfZeditwin� r �7/opt/alt/python37/lib64/python3.7/idlelib/autoexpand.py�__init__ s zAutoExpand.__init__c C s� | j �d�}| j �dd�}| js.| �� }d}n*| j\}}}}||ksL||krX| �� }d}|sh| �� dS | �� }| j �dt|� d� || } |d t|� }|dkr�| �� | j � d| � | j �d�}| j �dd�}||||f| _dS )z1Replace the current word with the next expansion.�insertzinsert linestartzinsert lineendr �breakzinsert - %d chars� ) r �index�getr �getwordsr � getprevword�delete�lenr ) r ZeventZ curinsertZcurline�wordsr r �line�wordZnewwordr r r �expand_word_event s. z AutoExpand.expand_word_eventc C s� | � � }|sg S | j�dd�}t�d| d |�}~| j�dd�}t�d| d |�}~|sd|sdg S g }i }|�� x*|D ]"}|�|�r�qz|�|� |||< qzW x*|D ]"}|�|�r�q�|�|� |||< q�W |�|� |S )z?Return a list of words that match the prefix before the cursor.z1.0zinsert wordstartz\bz\w+\bzinsert wordend�end)r r r �re�findall�reverse�append) r r ZbeforeZwbeforeZafterZwafterr �dict�wr r r r 6 s4 zAutoExpand.getwordsc C sJ | j �dd�}t|�}x&|dkr<||d | jkr<|d }qW ||d� S )z)Return the word prefix before the cursor.zinsert linestartr r r N)r r r � wordchars)r r �ir r r r U s zAutoExpand.getprevwordN) �__name__� __module__� __qualname__�stringZ ascii_lettersZdigitsr r r r r r r r r r s r �__main__)�mainz!idlelib.idle_test.test_autoexpand� )� verbosity)�__doc__r r$ r r!
