Does basic, standard text formatting, and also understands Python comment blocks. Thus, for editing Python source code, this extension is really only suitable for reformatting these comment blocks or triple-quoted strings. Known problems with comment reformatting: * If there is a selection marked, and the first line of the selection is not complete, the block will probably not be detected as comments, and will have the normal "text formatting" rules applied. * If a comment block has leading whitespace that mixes tabs and spaces, they will not be considered part of the same block. * Fancy comments, like this bulleted list, aren't handled :-) c C s || _ d S )N)�editwin)�selfr � r �3/opt/alt/python37/lib64/python3.7/idlelib/format.py�__init__ s zFormatParagraph.__init__c C s t jdddddd�| _d S )N� extensionsr z max-width�int�H )�type�default)r Z GetOption� max_width)�clsr r r �reload" s zFormatParagraph.reloadc C s d | _ d S )N)r )r r r r �close' s zFormatParagraph.closeNc C s� |dkr| j n|}| jj}| j�� \}}|rF|rF|�||�}t|�}nt||�d��\}}}}|rpt|||�}n t ||�}|� ddd� ||kr�|� d|� |� � |� ||� |�||� |�� n |� d|� |�d� dS )a� Formats paragraph to a max width specified in idleConf. If text is selected, format_paragraph_event will start breaking lines at the max width, starting from the beginning selection. If no text is selected, format_paragraph_event uses the current cursor location to determine the paragraph (lines of text surrounded by blank lines) and formats it. The length limit parameter is for testing with a known value.
