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 1 .. 8 spaces, depending on its position in its line. If false, each tab is treated as a single character. 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. t u sL (\s+|[^\s\w]*\w+[^0-9\W]-(?=\w+[^0-9\W])|(?<=[\w\!\"\'\&\.\,\?])-{2,}(?=\w))s (\s+)s [%s][\.\!\?][\"\']?\ZiF t c C s | | _ | | _ | | _ | | _ | | _ | | _ | | _ | | _ | | _ t j | j j t j | _ t j | j j t j | _ d S( N( t widtht initial_indentt subsequent_indentt expand_tabst replace_whitespacet fix_sentence_endingst break_long_wordst drop_whitespacet break_on_hyphenst ret compilet wordsep_ret patternt Ut wordsep_re_unit wordsep_simple_ret wordsep_simple_re_uni( t selfR R R R R R R R R ( ( s /usr/lib64/python2.7/textwrap.pyt __init__s s c C sp | j r | j } n | j rl t | t rE | j | j } ql t | t rl | j | j } ql n | S( s _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.

(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 s invalid width %r (must be > 0)iR ( R t ValueErrort reverseR R R, R t stripR0 R1 R6 t join( R R( t linesR3 R4 t indentR t l( ( s /usr/lib64/python2.7/textwrap.pyt _wrap_chunks s4 % % !c C sD | j | } | j | } | j r7 | j | n | j | S( s^ 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.)
