CJKwrap

CJKwrap is a library for wrapping and filling CJK text.

CJKwrap fix the issue24665 because Python 2 will stay broken forever: https://bugs.python.org/issue24665.

CJKwrap support both Python 2 (2.6 and above) and Python 3 (3.3 and above).

CJKwrap is developed by Florent Gallaire f@gallai.re.

Download and Install

To install the last stable version from PyPI::

$ sudo pip install cjkwrap

To install the development version from GitHub::

$ git clone https://github.com/fgallaire/cjkwrap
$ cd cjkwrap
$ sudo python setup.py install

Or you can just use the cjkwrap.py file alone, nothing more needed!

Usage

is_wide() to know if a char is double-width, cjklen() and cjkslices() to replace built-in len() and slicing::

>>> import cjkwrap
>>> cjkwrap.is_wide(u"c")
False
>>> cjkwrap.is_wide(u"長")
True
>>> cjkwrap.cjklen(u"最終的には良い長さ")
18
>>> head, tail = cjkwrap.cjkslices(u"最終的には良い長さ", 6)
>>> print(head)
最終的
>>> print(tail)
には良い長さ

As cjklen() uses len() for non unicode stuff, you can safely do this::

>>> from cjkwrap import cjklen as len
>>> len(u"最終的には良い長さ")
18
>>> len([1, 2, 3, 4])
4

wrap() and fill() to replace the ones from the Python standard library::

>>> wrapped_cjk = cjkwrap.wrap(u"最終的に良いラッピング", 10)
>>> for line in wrapped_cjk: print(line)
... 
最終的に良
いラッピン
グ
>>> print(cjkwrap.fill(u"最終的に良いラッピング", 10))
最終的に良
いラッピン
グ

Mixed content is allowed::

>>> cjkwrap.cjklen(u"CJK 最終的には良い長さ")
22
>>> print(cjkwrap.fill(u"CJK 最終的には良い長さ", 10))
CJK 最終的
には良い長
