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 :-) � N)�idleConfc @ sI e Z d Z d d g f g Z d d � Z d d � Z d d d � Z d S) �FormatParagraph�format�Format Paragraph�<<format-paragraph>>c C s | | _ d S)N)�editwin)�selfr � r �</opt/alt/python34/lib64/python3.4/idlelib/FormatParagraph.py�__init__ s zFormatParagraph.__init__c C s d | _ d S)N)r )r r r r �close s zFormatParagraph.closeNc C sS | d k r0 t j d d d d d d d �} n | j j } | j j � \ } } | r~ | r~ | j | | � } t | � } n$ t | | j d � � \ } } } } | r� t | | | � } n t | | � } | j d d d � | | k r2| j d | � | j � | j | | � | j | | � | j � n | j d | � | j d � d S)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.
