The public interface consists of the wrap() and fill() methods; the other methods are just there for subclasses to override in order to tweak the default behaviour. If you want to completely replace the main wrapping algorithm, you'll probably have to override _wrap_chunks(). Several instance attributes control various aspects of wrapping: width (default: 70) the maximum width of wrapped lines (unless break_long_words is false) initial_indent (default: "") string that will be prepended to the first line of wrapped output. Counts towards the line's width. subsequent_indent (default: "") string that will be prepended to all lines save the first of wrapped output; also counts towards each line's width. expand_tabs (default: true) Expand tabs in input text to spaces before further processing. Each tab will become 0 .. 'tabsize' spaces, depending on its position in its line. If false, each tab is treated as a single character. tabsize (default: 8) Expand tabs in input text to 0 .. 'tabsize' spaces, unless 'expand_tabs' is false. replace_whitespace (default: true) Replace all whitespace characters in the input text by spaces after tab expansion. Note that if expand_tabs is false and replace_whitespace is true, every tab will be converted to a single space! fix_sentence_endings (default: false) Ensure that sentence-ending punctuation is always followed by two spaces. Off by default because the algorithm is (unavoidably) imperfect. break_long_words (default: true) Break words longer than 'width'. If false, those words will not be broken, and some lines might be longer than 'width'. break_on_hyphens (default: true) Allow breaking hyphenated words. If true, wrapping will occur preferably on whitespaces and right after hyphens part of compound words. drop_whitespace (default: true) Drop leading and trailing whitespace from lines. u uL (\s+|[^\s\w]*\w+[^0-9\W]-(?=\w+[^0-9\W])|(?<=[\w\!\"\'\&\.\,\?])-{2,}(?=\w))u (\s+)u [a-z][\.\!\?][\"\']?\ZiF u i c C s^ | | _ | | _ | | _ | | _ | | _ | | _ | | _ | | _ | | _ | | _ d S( N( u widthu initial_indentu subsequent_indentu expand_tabsu replace_whitespaceu fix_sentence_endingsu break_long_wordsu drop_whitespaceu break_on_hyphensu tabsize( u selfu widthu initial_indentu subsequent_indentu expand_tabsu replace_whitespaceu fix_sentence_endingsu break_long_wordsu drop_whitespaceu break_on_hyphensu tabsize( ( u- /opt/alt/python33/lib64/python3.3/textwrap.pyu __init__a s u TextWrapper.__init__c C s@ | j r | j | j � } n | j r< | j | j � } n | S( u� _munge_whitespace(text : string) -> string Munge whitespace in text: expand tabs and convert all other whitespace characters to spaces.

Chunks are not quite the same as words; see _wrap_chunks() for full details. As an example, the text Look, goof-ball -- use the -b option! breaks into the following chunks: 'Look,', ' ', 'goof-', 'ball', ' ', '--', ' ', 'use', ' ', 'the', ' ', '-b', ' ', 'option!' if break_on_hyphens is True, or in: 'Look,', ' ', 'goof-ball', ' ', '--', ' ', 'use', ' ', 'the', ' ', '-b', ' ', option!' otherwise. c S s g | ] } | r | � q S( ( ( u .0u c( ( u- /opt/alt/python33/lib64/python3.3/textwrap.pyu <listcomp>� s u& TextWrapper._split.<locals>.<listcomp>T( u break_on_hyphensu Trueu wordsep_reu splitu wordsep_simple_re( u selfu textu chunks( ( u- /opt/alt/python33/lib64/python3.3/textwrap.pyu _split� s u TextWrapper._splitc C s| d } | j j } xc | t | � d k rw | | d d k rj | | | � rj d | | d <| d 7} q | d 7} q Wd S( uf _fix_sentence_endings(chunks : [string]) Correct for sentence endings buried in 'chunks'.

(If 'break_long_words' is false, some lines may be longer than this.) Chunks correspond roughly to words and the whitespace between them: each chunk is indivisible (modulo 'break_long_words'), but a line break can come between any two chunks. Chunks should not have internal whitespace; ie. a chunk is either all whitespace or a "word". Whitespace chunks will be removed from the beginning and end of lines, but apart from that whitespace is preserved. i u invalid width %r (must be > 0)i u i����i����i����i����i����i����( u widthu ValueErroru reverseu subsequent_indentu initial_indentu lenu drop_whitespaceu stripu appendu popu _handle_long_wordu join( u selfu chunksu linesu cur_lineu cur_lenu indentu widthu l( ( u- /opt/alt/python33/lib64/python3.3/textwrap.pyu _wrap_chunks� s4 % % !u TextWrapper._wrap_chunksc C sD | j | � } | j | � } | j r7 | j | � n | j | � S( u^ wrap(text : string) -> [string] Reformat the single paragraph in 'text' so it fits in lines of no more than 'self.width' columns, and return a list of wrapped lines.

This can be used to make triple-quoted strings line up with the left edge of the display, while still presenting them in the source code in indented form. Note that tabs and spaces are both treated as whitespace, but they are not equal: the lines " hello" and " hello" are considered to have no common leading whitespace. (This behaviour is new in Python 2.5; older versions of this module incorrectly expanded tabs before searching for common leading whitespace.) u i u u line = %r, margin = %ru (?m)^N( u Noneu _whitespace_only_reu subu _leading_whitespace_reu findallu startswithu splitu AssertionErroru re( u textu marginu indentsu indentu line( ( u- /opt/alt/python33/lib64/python3.3/textwrap.pyu dedentU s& c sC � d k r d d � � n � � � f d d � } d j | � � S( uF Adds 'prefix' to the beginning of selected lines in 'text'.
