Internationalization

Kajiki provides supporting infrastructure for internationalizing and localizing templates. This includes functionality for extracing localizable strings from templates, as well as translation of localizable strings.

Basics

To internationalize and translate templates, other templating solutions require that you wrap all localizable strings in a gettext() function call (usually aliased to _() for brevity). In this case, you would write your templates similar to the following:

<p>${_('Hello, world!')}</p>

This approach, however, adds lots of noise to your templates. Kajiki does not require that you wrap localizable strings since it automatically finds all “translatable text” in XML templates (any text outside of an XML tag).

In order to actually use translation, you must replace the placeholder function in kajiki.i18n.gettext with the actual gettext function. For instance, you might place the following in your top-level script to enable the Python gettext module:

from gettext import gettext
from kajiki import i18n
i18n.gettext = gettext

Extraction

Kajiki also provides support for extracing all localizable strings found in a template. This functionality is integrated with the excellent message extraction framework provided by the Babel project. Typically, you would notify Babel of the location of your templates before running the extraction routine:

# Python source
[python:**.py]
# Kajiki Templates
[kajiki:**/templates/**.html]

Please consult the Babel documentation for further details. If all goes well, the extraction process should create a POT file containing the strings from your Kajiki templates and your Python source files.
