To help translate Deluge please register at the Launchpad translation site

To mark text for translation in Python and ExtJS wrap the string with the function _() like this:

torrent.set_tracker_status(_("Announce OK"))

For GTK you can move the translation out of the code and into the glade files:

<property name="label" translatable="yes">Max Upload Speed:</property>

For more details see: Python Gettext

These are the overall stages in gettext translation: POT (Portable Object Template) files -> _ PO (Portable Object) files_ -> MO (Machine Object) files

• potfiles.in created with create_potfiles_in.py
• deluge.pot created with gettextize.sh
• Upload deluge.pot located in deluge/i18n/ to translation site
• Wait for the translators to translate the text.
• Download the updated PO files for each language from the translation site, extract to deluge/i18n/ and strip the deluge- prefix:
  br for i in deluge-*.po; do j=echo $i | cut -d - -f2; cp $i $j; rm $i; done
• The binary MO files for each language are generated in setup.py by using the msgfmt.py script.

To enable WebUI to use translations update gettext.js by running gen_gettext.py script.

• podiff - Compare textual information in two PO files
• gtranslator - GUI po file editor
• Poedit - GUI po file editor

Verification that translations are working correctly can be performed by running deluge like this:

If you do not have a particular language installed on your system it will only translate based on the binary MO files for Deluge so some GTK text strings will remain in English.

LANGUAGE=fr deluge
LANGUAGE=ru_RU.UTF-8 deluge
