Our Eiffel Tower of Babylon

Overview

"Many [people] would simply love seeing their computer screen showing a lot less of English, and far more of their own language." -- gettext doc

Our aim is not only to provide a framework to ease the translation of Eiffel-written applications, allowing the user to chose his/her preferred language at runtime, but also to let the developer access information and formats based on users' locale.

Brief history

Orginally the internationalisation (i18n) project was started as a required project for an ETH Software Architecture course. The result was less then perfect; pages referring to this first version have been given an 'SA' prefix. Some members of this SA project team decided to rewrite the library as a semester project. Pages on the wiki not prefixed with 'SA' are either applicable to both or to the semester project.

What is internationalisation?

The first thing that comes to mind is translation. But internationalisation isn't restricted to enabling translation: it includes making it possible to localise notations (time, date, numbers), measures, paper size, and much more.

What should we achieve?

  • Applications should be able to load localized strings at runtime and be provided with localized format strings (e.g date format).
  • Developers can use tools that automagically extract strings from source code and can try to get them translated in a file to distribute along with the application.
  • Users will still be unhappy and get depressed but in their own language, which we can all agree is a significant step forward.

Specific goals of the semester project

The new i18n library should provide translation as well as date, time, value and currency formatting. It should run on at least windows (with and without .NET) and linux.

Status

As of 16 October 2006 we have all features working and almost all tested. Some difficulty exists with the windows installation procedure. The linux version works without problems.
