annotate doc/index.txt @ 52:4df5e8994657
Added round-half-even (banker's rounding) support.
Moved a couple of unit-tests from docstrings to a separate file.

15 Simple Internationalization for Python Applications | |
16 --------------------------------------------------- | |
17 | |
18 Babel is an integrated collection of utilities that assist in | |
19 internationalizing and localizing Python applications, with an | |
20 emphasis on web-based applications. | |

22 * `Working with Message Catalogs <catalogs.html>`_ | |
23 * `Locale Display Names <display.html>`_ | |
24 * `Number and Date Formatting <formatting.html>`_ | |
25 * `Command-Line Interface <cmdline.html>`_ | |
26 * `Distutils/Setuptools Integration <setup.html>`_ | |
27 * `Generated API Documentation <api/index.html>`_ | |
28 | |
29 Introduction | |
30 ------------ | |
31 | |
32 The functionality Babel provides for internationalization (I18n) and | |
33 localization (L10N) can be separated into two different aspects: | |
34 | |
35 * tools to build and work with ``gettext`` message catalogs, and | |
36 * a Python interface to the CLDR (Common Locale Data Repository), providing | |
37 access to various locale display names, localized number and date | |
38 formatting, etc. | |
39 | |
40 While the Python standard library includes a | |
41 `gettext <http://docs.python.org/lib/module-gettext.html>`_ module that enables | |
42 applications to use message catalogs, it requires developers to build these | |
43 catalogs using GNU tools such as ``xgettext``, ``msgmerge``, and ``msgfmt``. | |
44 And while ``xgettext`` does have support for extracting messages from Python | |
45 files, it does not know how to deal with other kinds of files commonly found | |
46 in Python web-applications, such as templates, nor does it provide an easy | |
47 extensibility mechanism to add such support. | |
48 | |
49 Babel addresses this by providing a framework where various extraction methods | |
50 can be plugged in to a larger message extraction framework, and also removes | |
51 the dependency on the GNU ``gettext`` tools for common tasks, as these aren't | |
52 necessarily available on all platforms. See `Working with Message Catalogs`_ | |
53 for details on this aspect of Babel. | |
54 | |
55 Furthermore, while the Python standard library does include support for basic | |
56 localization with respect to the formatting of numbers and dates (the | |
57 `locale <http://docs.python.org/lib/module-locale.html>`_ module, among others), | |
58 this support is based on the assumption that there will be only one specific | |
59 locale used per process (at least simultaneously.) Also, it doesn't provide | |
60 access to other kinds of locale data, such as the localized names of countries, | |

61 languages, or time-zones, which are frequently needed in web-based applications. |

63 For these requirements, Babel includes data extracted from the `Common Locale | |
64 Data Repository (CLDR) <http://unicode.org/cldr/>`_, and provides a number of | |
65 convenient methods for accessing and using this data. See `Locale Display | |
66 Names`_ and `Number and Date Formatting`_ for more information on this aspect | |
67 of Babel. | |
