Summary

Our task is to find out the possible main difficulties that will be encoutered during both design and implementation of the i18n framework.

Main focuses are:

• state of the Unicode implementation
• strings usage in Vision2
• runtime generated/composed strings with variables

String types and their possible extraction difficulties

Constant String

Workbench_name: STRING is "EiffelStudio"

Difficulties

Possible Solution

String with label specific syntax

m_to_lower: STRING is "Set to &Lowercase%TCtrl+Shift+U"

Difficulties

• Bad readability for the traducer
• Possible

Possible Solution

Important Classes

• INTERFACE_NAMES: Include all the strings of the ES interface (buttons, labels, shortcuts...)
• TEXT_FORMATTER: Text formatter for all text output formatting

• STRING_GENERAL: "Common ancestors to all STRING classes." [base]
  • STRING: [base]
    • UC_STRING: Unicode strings [gobo]
      • UC_UTF8_STRING: Unicode strings with UTF-8 encoding
  • STRING_32: [base]
• UC_CHARACTER: Unicode characters [gobo]

• KS_STRING: Portable interface for class STRING [Gobo]
• cluster: "gobo.kernel.unicode"

• ERROR: Error object sent by the compiler to the workbench. Ancestor class of all error classes (WARNING, SYNTAX_ERROR, INTERRUPT_ERROR, LACE_ERROR,EIFFEL_ERROR...)

• WIDE_CHARACTER: Unicode characters, with comparison operations [base]
