Application in your Lingo- Tracing the story
Anand Subramanian Wipro Technologies

The Plan

• Flashback basics
• Metamorphosis
• Creating an internationalized application
• Obtaining translatable information
• Perform translation
• Processing the translation
• Running the application
• Demo

3
Why, What, Where?

• Internationalization (i18N)
• Localization (L10N)
• Translation
• One code base for the world
• English is just another language

4
The Localization Journey
Build an i18N App
Extract Displayable Strings
Translate the Strings
Install and Run the Application
Build the Binary
5
Building an i18N Application

• Mark your strings. That's vital.
• Existing apps
• Track down strings Eyeball the GUI, Code
• _ them.
• New apps
• GNU Toolkits to get inherent support for i18N
• UI builder tools (E.g. Glade)

GUI/String Freeze aids effective i18N-ization
6
Building an i18N Application ..contd.

• Marking a String
• GNU gettext
• In the code,
• Header file inclusion for gettext wrapper
  functions
• Wrapping strings with library specific functions
• Before
• popup_display ("Making English just another
  language")
• After
• popup_display (_("Making English just another
  language"))

7
Kick-start the Translation Trip

• Fundas First...
• Portable Objects
• msgid lt-gt msgstr pairs
• Build tweaking for automated extraction
• autogen.sh, configure.in, Makefile.am

8
The Real Action Translating

• The Aides
• Language teams
• Tools
• Linux Yudit, Kbabel, Gtranslator, Poedit, Gedit
• Windows Poedit, Yudit, Takhti(hindi)

9
Build/Install binary files

• Tweaks
• autogen.sh, configure.in, Makefile.am

10
Your App is Ready!

• Set the 'locale'.
• E.g.
• GDM Login screen
• Environment variable
• LANG

11
Oh, By the way...

• gettext_noop() - The N_() markup
• Before ShapeData shapes "circle", "square",
  "triangle", NULL
• After ShapeData shapes N_("circle"),
  N_("square"), N_("triangle"), NULL
• Changes in main()
• bindtextdomain (GETTEXT_PACKAGE,
  GEDIT_LOCALEDIR)
• bind_textdomain_codeset (GETTEXT_PACKAGE,
  "UTF-8")
• textdomain (GETTEXT_PACKAGE)

12
And also...

• Translation Fixes app's output
• Input Keymaps required

Output
Input
Application

Summing-up
Build an i18N App (GTK, Glade)
Extract Strings (PO, xgettext, intltool)
Translate the Strings (Yudit, Poedit)
Install and Run the Application (LANG, locale)
Build the Binary (MO, msgfmt)

Happy Translating!
