| 3 | This module provides internationalization (I18N) and localization (L10N)
|
|---|
| 4 | support for your Python programs by providing an interface to the GNU gettext
|
|---|
| 5 | message catalog library.
|
|---|
| 6 |
|
|---|
| 7 | I18N refers to the operation by which a program is made aware of multiple
|
|---|
| 8 | languages. L10N refers to the adaptation of your program, once
|
|---|
| 9 | internationalized, to the local language and cultural habits.

|
|---|
| 15 | #
|
|---|
| 16 | # Martin von Loewis, who wrote the initial implementation of the underlying
|
|---|
| 17 | # C-based libintlmodule (later renamed _gettext), along with a skeletal
|
|---|
| 18 | # gettext.py implementation.
|
|---|
| 19 | #
|
|---|
| 20 | # Peter Funk, who wrote fintl.py, a fairly complete wrapper around intlmodule,
|
|---|
| 21 | # which also included a pure-Python implementation to read .mo files if
|
|---|
| 22 | # intlmodule wasn't available.
|
|---|
| 23 | #
|
|---|
| 24 | # James Henstridge, who also wrote a gettext.py module, which has some
|
|---|
| 25 | # interesting, but currently unsupported experimental features: the notion of
|
|---|
| 26 | # a Catalog class and instances, and the ability to add to a catalog file via
|
|---|
| 27 | # a Python API.
|
|---|
| 28 | #
|
|---|
| 29 | # Barry Warsaw integrated these modules, wrote the .install() API and code,
|
|---|
| 30 | # and conformed all C and Python code to Python's coding standards.
|
|---|
| 31 | #
|
|---|
| 32 | # Francois Pinard and Marc-Andre Lemburg also contributed valuably to this
|
|---|
| 33 | # module.
|
|---|
| 34 | #
|
|---|
| 35 | # J. David Ibanez implemented plural forms. Bruno Haible fixed some bugs.

| 37 | # TODO:
|
|---|
| 38 | # - Lazy loading of .mo files. Currently the entire catalog is loaded into
|
|---|
| 39 | # memory, but that's probably bad for large translated programs. Instead,
|
|---|
| 40 | # the lexical sort of original strings in GNU .mo files should be exploited
|
|---|
| 41 | # to do binary searches and lazy initializations. Or you might want to use
|
|---|
| 42 | # the undocumented double-hash algorithm for .mo files with hash tables, but
|
|---|
| 43 | # you'll need to study the GNU gettext code to do this.
