A library to manipulate gettext files (po and mo files).
Table of Contents
polib allows you 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.
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
Note: this is not recommended in a production environment.
$ hg clone https://polib.googlecode.com/hg/ polib $ cd polib $ python setup build $ sudo python setup.py install
>>> 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.occurences = [('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')
- fixed issue #0017: UnicodeDecodeError while writing a mo-file,
- fixed issue #0018: implemented support for msgctxt,
- fixed bug when compiling plural msgids/strs,
- API docs are no longer included, hopefully next release will ship with sphinx documentation,
- parse msg plural entries correctly when reading mo files,
- fixed issue #0020 and #0021: added ability to check for duplicate when adding entries to po/mo files, this is optional and not enabled by default because it slows down considerably the library,
- fixed issue #0022: unescaping code is insufficient,
- fixed issue #0023: encoding error when saving mo file as po file (thanks to sebastien.sable for the patch !).
- fixed issue #0007: use the codecs module to open files,
- fixed issue #0014: plural forms are not saved correctly in the mo file (thanks lorenzo.gil.sanchez for the patch),
- fixed issue #0015: no LICENSE file included in tarball,
- removed Version/Date from README,
- added test pot files to MANIFEST.in,
- performance improvment in find() method (thanks Thomas !).
- fixed issue #0006: plural msgstrs were saved unsorted,
- fixed issue #0008: long comment lines broke ‘save()’ method,
- removed performance shortcuts: they were in fact inefficient, I was misleaded by the python profile module, kudos to Thomas for making me realise that,
- fixed issue #0010: wrong polib version number,
- fixed issue #0011: occurrences parsing is now more robust and can handle weird references formats (like in eToys OLPC po files),
- fixed issue #0012: improved merge() method.
- fixed bug #0005: percent_translated divide by 0 on empty po files,
- fixed bug #0004: occurences that have hiphens are wrapped when they should not,
- changes in how encoding is handled,
- remove deprecation warnings for typo “occurences”,
- added POEntry.__cmp__() method to sort entries like gettext does,
- fixed POEntry.transalated(),
- added a merge() method to POFile class, that behaves like the gettext msgmerge utility,
- obsolete entries are now written at the end of the file and with only msgid/msgstr like gettext does,
- fixed some bugs in mo files parsing,
- renamed quote/unquote functions to escape/unescape,
- various cosmetic changes.
- fixed bug #0002: typo: “occurences” instead of “occurrences”,

- added a find() method to _BaseFile class,
- proper handling of quoting and unquoting,
- proper handling of multiline strings in metadata
- speed improvements,
- polib can now compile mo files,
- unicode support,
- fixed bug #0001: global name ‘sorted’ is not defined” on python 2.3.
