| """Internationalization and localization support. |
| |
| This module provides internationalization (I18N) and localization (L10N) |
| support for your Python programs by providing an interface to the GNU gettext |
| message catalog library. |
| |
| I18N refers to the operation by which a program is made aware of multiple |
| languages. L10N refers to the adaptation of your program, once |
| internationalized, to the local language and cultural habits. |
| |
| """ |
| |
| # This module represents the integration of work, contributions, feedback, and |
| # suggestions from the following people: |
| # |
| # Martin von Loewis, who wrote the initial implementation of the underlying |
| # C-based libintlmodule (later renamed _gettext), along with a skeletal |
| # gettext.py implementation. |
| # |
| # Peter Funk, who wrote fintl.py, a fairly complete wrapper around intlmodule, |
| # which also included a pure-Python implementation to read .mo files if |
| # intlmodule wasn't available. |
| # |
| # James Henstridge, who also wrote a gettext.py module, which has some |
| # interesting, but currently unsupported experimental features: the notion of |
| # a Catalog class and instances, and the ability to add to a catalog file via |
| # a Python API. |
| # |
| # Barry Warsaw integrated these modules, wrote the .install() API and code, |
| # and conformed all C and Python code to Python's coding standards. |
| # |
| # Francois Pinard and Marc-Andre Lemburg also contributed valuably to this |
| # module. |
| # |
| # J. David Ibanez implemented plural forms. Bruno Haible fixed some bugs. |
| # |
| # TODO: |
| # - Lazy loading of .mo files. Currently the entire catalog is loaded into |
| # memory, but that's probably bad for large translated programs. Instead, |
| # the lexical sort of original strings in GNU .mo files should be exploited |
| # to do binary searches and lazy initializations. Or you might want to use |
| # the undocumented double-hash algorithm for .mo files with hash tables, but |
| # you'll need to study the GNU gettext code to do this. |
| # |
| # - Support Solaris .mo file formats. Unfortunately, we've been unable to |
| # find this format documented anywhere. |

| # |
| # import gettext |
| # cat = gettext.Catalog(PACKAGE, localedir=LOCALEDIR) |
| # _ = cat.gettext |
| # print _('Hello World') |
| |
| # The resulting catalog object currently don't support access through a |
| # dictionary API, which was supported (but apparently unused) in GNOME |
| # gettext. |
