Update of the localization files

If any change has been made on any string in the source, localization files must be updated.

To facilitate this, we developed a script to do this :
tools/localization/updateLocalizationModule.sh

Using this script is straightforward.

export SCI=/path/to/scilab/source/tree/
sh tools/localization/updateLocalizationModule.sh <module_name> 

If module_name is process_all, it will regenerate all localization files of Scilab.

Thanks to gettext tools, this script is intelligent. It will detect if a string has been changed (it will then update the line in all the .po files of a module), added (it will add it) or removed.

Localization files

Localization files are stored in :

# SCI/modules/<module>/locales/<locale>/messages.po

For example, the French localization files of the interpolation module is modules/interpolation/locales/fr_FR/messages.po

There are one localization files per module and per language. At the moment, we have English (en_US) and French (fr_FR).

Java localization

gettext is generating java classes (called ResourceBundle) which contain the localized strings. In the root Makefile.am of Scilab, we generate this class with the command: \$(MSGFMT) \$(MSGFMT_OPTS) --statistics --locale \$\$LOCALE -r org.scilab.modules.localization.Messages --java2 -d \$(top_builddir)/modules/localization/build/classes/ \$\$POFILE; which is going to generate classes into SCI/modules/localization/build/classes/org/scilab/modules/localization/Messages*class

To manage the localization, we created the class (modules/localization/src/java/org/scilab/modules/localization/Messages.java) which is in charge of:

• loading the bundle (if a switch back to english if not available in the user language)

• manage the translation of a string through the getText(String) method

To translate a string, it is straightforward:

import org.scilab.modules.localization.Messages;
[...}
Messages.gettext("My own string");

Most of the message of the GUI are located into XML files (like modules/gui/etc/main_menubar.xml). These files are processed by 2 pass:

• with a sed script, extract messages from the label tag and create a fake C file which will be processed by the updateLocalizationModule.sh script among the rest of the files.

• extract gettext("my message") from the instructions

Synchronize Launchpad => Scilab

When a language has been translated under Launchpad/Rosetta and there is the need to synchronize Scilab source tree with the latest version of the localization files.

1. Request a full download of the localization files

2. Unpack the archive
3. Under Linux:
   1. export SCI=/path/to/your/source/tree
   2. sh \$SCI/tools/localization/dispatchLocalizationFile.sh /path/to/the/unpack/archive/

All localization files should be dispatched into the Scilab source tree.
