chsize = chinese character size in shell

get the real size of a character use in shell(with monospace font)

for example

'a'  use 1
'啊' use 2

In [1]: from chsize import chlen, echlen

In [2]: chlen('hello world!')
Out[2]: 12

In [3]: chlen('你好世界！')
Out[3]: 10

In [4]: echlen('我你2我')
Out[4]: [('我', 2), ('你', 2), ('2', 1), ('我', 2)]

recently I need to auto generate rst layout doc for Sphinx, but when generate table

# Ipython Python 3.4.3

In [1]: u' {:{}} |'.format( a', 2)
Out[1]: ' a  |'

In [2]: u' {:{}} |'.format('我', 2)
Out[2]: ' 我  |'

because python only take care of count of word, do not care if it is half width or full width.

inspired from http://stackoverflow.com/questions/10959227/how-to-distinguish-whether-a-word-is-half-width-or-full-width

detail

3400—4DBF

now only support for some commonly used word in work

1. half-width and full width FF00—FFEF
2. chinese/japanese/korean character 4E00—9FFF
