Python codec for converting between a string of ASCII and Unicode chars maintaining readability
Project description
Upcoming Breaking Change!
When RotUnicode was released through version 0.3.0, it was released under the namespace box.util. In version 1.1.2, importing rotunicode became easier:
from rotunicode import RotUnicode
vs.
from box.util.rotunicode import RotUnicode
In version 2.0.0, however, you will no longer be able to import rotunicode from box.util.
About
RotUnicode is a Python codec that can convert a string of ASCII characters to a Unicode string with non-ASCII characters maintaining readability.
>>> import codecs
>>> from rotunicode import RotUnicode
>>> codecs.register(RotUnicode.search_function)
>>> 'Hello World!'.encode('rotunicode')
Ĥȅľľő Ŵőŕľď!
>>> 'Ĥȅľľő Ŵőŕľď!'.decode('rotunicode')
Hello World!
RotUnicode is extremely helpful in testing your application because it makes it easy to create strings with non-ASCII characters. Example -
>>> import os, errno
>>> name = 'foo'.encode('rotunicode')
>>> os.mkdir(name)
>>> print(name)
ƒőő
>>> os.path.exists(name)
True
>>> os.statvfs(name)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-2:
ordinal not in range(128)
This bug is filed at http://bugs.python.org/issue18695.
Supported Characters
RotUnicode converts lower case and upper case characters of the English alphabet and digits 0 to 9 to non-ASCII characters. All characters that are outside this range are left as is.
>>> 'हेलो World!'.encode('rotunicode')
हेलो Ŵőŕľď!
>>> 'हेलो Ŵőŕľď!'.decode('rotunicode')
हेलो World!
Installation
To install, simply:
pip install rotunicode
Contribute
See CONTRIBUTING.
Setup
Create a virtual environment and install packages:
mkvirtualenv rotunicode
pip install -r requirements-dev.txt
Testing
Run all tests using:
tox
The tox tests include code style checks via pep8 and pylint.
Why is this named RotUnicode?
RotUnicode stands for rotate-to-unicode. Or rotten-unicode for those who have nightmares about Unicode. It was inspired by Rot13.
