This patch does not remove all occurrences of the words in question. Rather, I went through all of the occurrences of the words listed below, and judged if they a) suggested the reader had some kind of knowledge/experience, and b) if they added anything of value (including tone of voice, etc). I left most of the words alone. I looked at the following words: - simply/simple - easy/easier/easiest - obvious - just - merely - straightforward - ridiculous Thanks to Carlton Gibson for guidance on how to approach this issue, and to Tim Bell for providing the idea. But the enormous lion's share of thanks go to Adam Johnson for his patient and helpful review.

Overview
|
|
========
|
|
|
|
The goal of internationalization and localization is to allow a single Web
|
|
application to offer its content in languages and formats tailored to the
|
|
audience.
|
|
|
|
Django has full support for :doc:`translation of text
|
|
</topics/i18n/translation>`, :doc:`formatting of dates, times and numbers
|
|
</topics/i18n/formatting>`, and :doc:`time zones </topics/i18n/timezones>`.
|
|
|
|
Essentially, Django does two things:
|
|
|
|
* It allows developers and template authors to specify which parts of their apps
|
|
should be translated or formatted for local languages and cultures.
|
|
* It uses these hooks to localize Web apps for particular users according to
|
|
their preferences.
|
|
|
|
Translation depends on the target language, and formatting usually depends on
|
|
the target country. This information is provided by browsers in the
|
|
``Accept-Language`` header. However, the time zone isn't readily available.
|
|
|
|
Definitions
|
|
===========
|
|
|
|
The words "internationalization" and "localization" often cause confusion;
|
|
here's a simplified definition:
|
|
|
|
.. glossary::
|
|
|
|
internationalization
|
|
Preparing the software for localization. Usually done by developers.
|
|
|
|
localization
|
|
Writing the translations and local formats. Usually done by translators.
|
|
|
|
More details can be found in the `W3C Web Internationalization FAQ`_, the `Wikipedia article`_ or the `GNU gettext documentation`_.

|
|
.. _GNU gettext documentation: https://www.gnu.org/software/gettext/manual/gettext.html#Concepts
|
|
.. _Wikipedia article: https://en.wikipedia.org/wiki/Internationalization_and_localization
|
|
|
|
.. warning::
|
|
|
|
Translation and formatting are controlled by :setting:`USE_I18N` and
|
|
:setting:`USE_L10N` settings respectively. However, both features involve
|
|
internationalization and localization. The names of the settings are an
|
|
unfortunate result of Django's history.
|
|
|
|
Here are some other terms that will help us to handle a common language:
|
|
|
|
.. glossary::
|
|
|
|
locale name
|
|
A locale name, either a language specification of the form ``ll`` or a
|
|
combined language and country specification of the form ``ll_CC``.
|
|
Examples: ``it``, ``de_AT``, ``es``, ``pt_BR``. The language part is
|
|
always in lowercase and the country part in upper case. The separator is
|
|
an underscore.
|
|
|
|
language code
|
|
Represents the name of a language. Browsers send the names of the
|
|
languages they accept in the ``Accept-Language`` HTTP header using this
|
|
format. Examples: ``it``, ``de-at``, ``es``, ``pt-br``. Language codes
|
|
are generally represented in lowercase, but the HTTP ``Accept-Language``
|
|
header is case-insensitive. The separator is a dash.
|
|
|
|
message file
|
|
A message file is a plain-text file, representing a single language,
|
|
that contains all available :term:`translation strings
|
|
<translation string>` and how they should be represented in the given
|
|
language. Message files have a ``.po`` file extension.
|
|
|
|
translation string
|
|
A literal that can be translated.
|
|
|
|
format file
|
|
A format file is a Python module that defines the data formats for a given
|
|
locale.
