Introduction

polib is a library to manipulate, create, modify gettext files (pot, po and mo files). You can load existing files, iterate through it's entries, add, modify entries, comments or metadata, etc... or create new po files from scratch.

polib is pretty stable now and is used by many opensource projects.

Installation

Note: chances are that polib is already packaged for your linux/bsd system, if so, we recommend you use your OS package system, if not then choose a method below:

$ easy_install polib

$ pip install polib

$ tar xzfv polib-x.y.z.tar.gz
$ cd polib-x.y.z
$ python setup build
$ sudo python setup.py install

$ hg clone http://bitbucket.org/izi/polib/
$ cd polib
$ python setup build
$ sudo python setup.py install

Basic usage example

>>> import polib
>>> # load an existing po file
>>> po = polib.pofile('tests/test_utf8.po')
>>> for entry in po: print entry.msgid, entry.msgstr
>>> # add an entry
>>> entry = polib.POEntry(msgid='Welcome', msgstr='Bienvenue')
>>> entry.occurrences = [('welcome.py', '12'), ('anotherfile.py', '34')]
>>> po.append(entry)
>>> # save our modified po file
>>> po.save()
>>> # compile mo file
>>> po.save_as_mofile('tests/test_utf8.mo')
