In this post, we will write a Python script to automatically convert Traditional Chinese (zh_TW) PO file to Simplified Chinese (zh_CN) by OpenCC (Open Chinese Convert) and pyOpenCC (OpenCC Python binding). Please read my previous post [1] to install OpenCC and pyOpenCC first.

Source Code

The zh_TW PO file for test:

messages.po | repository | view raw 
# Chinese translations for PACKAGE package.
# Copyright (C) 2013 THE PACKAGE'S COPYRIGHT HOLDER
# This file is distributed under the same license as the PACKAGE package.
# Automatically generated, 2013.

The Python script:

tw2cn.py | repository | view raw 
#!/usr/bin/env python
# -*- coding:utf-8 -*-

import re
import pyopencc
tw2cn = pyopencc.OpenCC('zht2zhs.ini').convert


if __name__ == '__main__':
  with open("locale/zh_TW/LC_MESSAGES/messages.po", 'r') as ftw:
    with open("locale/zh_CN/LC_MESSAGES/messages.po", "w") as fcn:
      for line in ftw.readlines():
        if 'zh_TW' in line:
          fcn.write(line.replace('zh_TW', 'zh_CN'))
        elif line.startswith('msgstr'):
          try:
            fcn.write(re.sub('msgstr "(.+)"', lambda m: 'msgstr "%s"' % tw2cn(m.group(1)), line))
          except UnicodeEncodeError:
            fcn.write(re.sub('msgstr "(.+)"', lambda m: 'msgstr "%s"' % tw2cn(m.group(1)), line).encode('utf-8'))
        else:
          fcn.write(line)

Tested on: Ubuntu Linux 15.10, Python 2.7.10, opencc 0.4.3-2build1, pyopencc-0.4.2.2.
