Class gnu.gettext.GettextResource
java.lang.Object
|
+----java.util.ResourceBundle
|
+----gnu.gettext.GettextResource
- public abstract class GettextResource
- extends ResourceBundle
This class implements the main GNU libintl functions in Java.
Using the GNU gettext approach, compiled message catalogs are normal
Java ResourceBundle classes and are thus interoperable with standard
ResourceBundle based code.
The main differences between the Sun ResourceBundle approach and the
GNU gettext approach are:
- In the Sun approach, the keys are abstract textual shortcuts.
In the GNU gettext approach, the keys are the English/ASCII version
of the messages.
- In the Sun approach, the translation files are called
"Resource_locale.properties" and have non-ASCII
characters encoded in the Java
\unnnn syntax. Very few editors
can natively display international characters in this format. In the
GNU gettext approach, the translation files are called
"Resource.locale.po"
and are in the encoding the translator has chosen. Many editors
can be used. There are at least three GUI translating tools
(Emacs PO mode, KDE KBabel, GNOME gtranslator).
- In the Sun approach, the function
ResourceBundle.getString throws a
MissingResourceException when no translation is found.
In the GNU gettext approach, the gettext function
returns the (English) message key in that case.
- In the Sun approach, there is no support for plural handling.
Even the most elaborate MessageFormat strings cannot provide decent
plural handling. In the GNU gettext approach, we have the
ngettext function.
To compile GNU gettext message catalogs into Java ResourceBundle classes,
the msgfmt program can be used.
