EiffelStudio 21.11.x Releases

21.11.xx.yyyy (Month Day 2021)

New features

  • compiler: Supported a unified syntax to access loop cursor features inside an iteration form of a loop for both keyword-based and Unicode-based loop variants. The current item is accessed by the cursor name. The cursor feature is accessed by preceding the cursor name with the symbol @. For example:
 x: array ¦ (@ x.target_index \\ 2 = 0 ⇒ x > 0) -- All elements at even positions are positive.
        -- Print all elements of a table prefixed with their keys.
    across table as y loop
        print (@ y.key)
        print (": ")
        print (y)
  • EiffelStudio: Added a source control management tool, supporting Subversion and Git.


  • EiffelStudio: Added scripts (for Unixes) to open an external editor, to open a URL, and to open a terminal.
  • EiffelStudio: Migrated to GTK3 on non-Windows platforms (Linux, macOS, etc.).
  • EiffelStudio: Used user-controlled editor font in several tools.
  • compiler: Used the same indentation for assertion subclauses with and without tags in flat forms and pretty-printer output.

Bug fixes

compiler: test#syntax076 — Removed a restriction on using forward and back-slashes for user-defined operators (the following restrictions still apply: \\, /, // can only be used as binary operators).

Feature removed

User changes

  • compiler: test#attach130 — Added a validity check that the type of an inspect expression is attached when compiled in void-safe mode.
  • compiler: Changed to report an iteration form of a loop with keyword is as obsolete. The contemporary syntax is to use the loop with keyword as and symbol @ to access cursor features.
  • compiler: Changed to report a user-defined operator @ as obsolete (in many cases, the bracket operator replaces it).

Developer changes

  • library (json): Added a date time serializer.
  • library (json): Added the possibility to use the reflector serializer with JSON_BASIC_SERIALIZATION.
  • library (vision2): Updated the checkbox drawing, and added a new is_indeterminate state.
  • library (EiffelWeb): Fixed WSF_REQUEST when searching for a table item with the name such as tb[k1][k2].
  • library (cms): Improved the administration part, and followed recommendation for email sending.
  • library (vision2): Switched to GTK3 on non-Windows platforms (to use GTK2, set the project variable vision_implementation to gtk2).
