EiffelStudio 17.11.x Releases

Beta download: https://ftp.eiffel.com/pub/beta/17.11/

17.11.x.x

New features

• compiler: Supported typed manifest arrays of the form {ARRAY [FOO]} <<bar, qux>> that allow for explicit specification on the array type (see more at eiffel.org).
• compiler: Changed the way to compute a type of a manifest array from when no explicit type is specified, it no longer depends on the type of the target of a reattachment where the array is used as a source (see more at eiffel.org).

Improvements

• library (Base): Updated CHARACTER_PROPERTIES to use Unicode 10.0.0 instead of 6.2.0.

Feature removed

Bug fixes

• compiler: test#exec370 - Fixed a bug that might cause a crash of a program because of incorrect code generation for conditional expressions involving values of reference and expanded types (e.g., if foo then "bar" else 5 end).

User changes

• compiler: Changed an algorithm to compute a type of a conditional expression, now it does not depend on the order of expressions used in the branches, and always exists, i.e. there is no VWCE error anymore (more details are available at eiffel.org).
• compiler: Added a warning reported when a manifest array type is computed using a target type of the reattachment the array is involved in as a source. The warning can be disabled in the project settings during the first year after the release, cannot be disabled afterwards, and becomes an error after 1.5 year after the release.
