ebcdic 0.6.0

Additional EBCDIC codecs

Ebcdic is a Python package adding additional EBCDIC encodings for data exchange with legacy system. It works with Python 2.6+ and Python 3.1+.

Installation

Ebcdic is available from https://pypi.python.org/pypi/ebcdic and can be installed using pip:

pip install ebcdic

Example usage

>>> import ebcdic
>>> 'hello world'.encode('cp1141')
b'\x88\x85\x93\x93\x96@\xa6\x96\x99\x93\x84O'

Supported codecs

Python already ships with the following EBCDIC codec:

• cp500 - international (without Euro sign)

The ebcdic package currently adds:

• cp1140 - Australia, Brazil, Canada, New Zealand, Portugal, South Africa, USA

• cp1141 - Germany, Austria

• cp1142 - Denmark, Norway

• cp1143 - Finland, Sweden

• cp1144 - Italy

• cp1145 - Latin America, Spain

• cp1146 - Great Britain, Ireland, North Ireland

• cp1147 - France

• cp1148 - international

• cp1149 - Iceland

It also adds legacy codecs that do not include the Euro sign:

• cp037 - similar to cp1140

• cp273 - similar to cp1141

• cp277 - similar to cp1142

• cp278 - similar to cp1143

• cp280 - similar to cp1144

• cp284 - similar to cp1145

• cp285 - similar to cp1146

• cp297 - similar to cp1147

• cp871 - similar to cp1149

• cp1047 - Open Systems (MVS C compiler)

Source code

These codecs have been generated using CodecMapper available from https://github.com/roskakori/CodecMapper. Read the README in order to to build the ebcdic package from source.

To add another 8 bit EBCDIC codec just extend the ant target ebcdic in build.xml using a line like:

<arg value="cpXXX" />

Changes

Version 0.6, 2014-11-15

• Added support for Python 2.6+ and 3.1+ (#1).

• Included a modified version of gencodec.py that still builds maps instead of tables so the generated codecs work with Python version earlier than 3.3. It also does a from __future__ import unicode_literals so the codecs even work with Python 2.6+ using the same source code. As a side effect, this simplifies building the codecs because it removes the the need for a local copy of the cpython source code.

Version 0.5, 2014-11-13

• Initial public release
