sources:
* :source:`py/compat/`
* :source:`py/builtin/`
The compat and builtin namespaces help to write code using newer python features on older python interpreters.
:api:`py.compat`
----------------
:api:`py.compat` provides fixed versions (currently taken from Python 2.4.4) of
a few selected modules to be able to use them across python versions. Currently these are:
* doctest
* optparse
* subprocess
* textwrap
Note that for example ``import doctest`` and ``from py.compat import doctest`` result
into two different module objects no matter what Python version you are using.
So you should only use exactly one of these to avoid confusion in your program.

"""
Object for wrapping/filling text. 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 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'.
