EiffelStudio 15.12.x Releases

New features

  • compiler - Supported tuple type unfolding that allows to avoid explicit nested tuple type declarations when there is only one formal generic type that is constrained to a TUPLE type. For example, for the class
FOO [X, T -> TUPLE, Y]

the type declarations

FOO [A, TUPLE [B, C], D]
FOO [A, TUPLE [B, C, E], D]

can be written as

FOO [A, B, C, D]
FOO [A, B, C, E, D]


  • compiler: test#scoop074 - Propagated controlled status of an object test expression to an associated object test local to avoid unnecessary wrapping for this local.
  • compiler: bug#19147 - Provided new configuration options are "workbench_c_basket_limit" and "finalized_c_basket_limit" that can be used in ".../studio/eifinit/general.cfg" to specify maximum limits of C files that can be generated in one directory in workbench and finalized modes respectively for the cases when C compilation fails because of too large C files.
  • compiler, library, runtime - Removed the first parameter in ROUTINE family classes (PROCEDURE, PREDICATE, FUNCTION). Combined with tuple unfolding, the following type declarations:

are written now as

  • EiffelStudio: Added a configuration file code_analysis.xml for default settings of Eiffel Inspector.
  • EiffelStudio: Changed order of inclusion and exclusion patterns saved in configuration files (ECF) to be lexicographically sorted.

Feature removed

Bug fixes

  • compiler: test#scoop075 - Fixed a code generation bug in finalized mode for separate feature calls that involve values of a pointer type.
  • compiler: bug#19120 (test#tuple019) - Fixed a bug that caused a compiler exception when a non-conforming value was assigned to a tuple field.
  • compiler: Made code analysis preference names and associated command-line options locale-independent.
  • compiler: Fixed generation of debugger breakpoint positions for tuple field assignment that was broken by the previous release.
  • compiler: test#attach049 - Fixed a bug that caused incorrect identification of certified attachment patterns (CAP) when target of Boolean operators like and and or is not of a Boolean type and therefore should not be taken into account when detecting CAPs.
  • compiler: test#attach114 - Fixed a bug that could lead to a feature call on void target if parenthesis alias calls were used in a creation procedure.
  • compiler: bug#17907 (test#incr417), bug#17913 (test#incr418), bug#17942 (test#incr419), test#incr432 - Fixed a bug in incremental recompilation that might cause wrong errors to be reported or a crash if there are source code errors involving qualified anchored types during recompilation.
  • compiler: test#attach115 - Fixed a bug that could lead to a feature call on void target if an empty loop of iteration form on an argument was used in a creation procedure.
  • EiffelStudio: bug#18713 (test#config039) - Significantly increased a limit on patterns specified in file rules of ECF (and project settings dialog) and improved error reporting when it is reached.

User changes

  • compiler: Changed option names of code analysis rules.
  • compiler: Used the same convention for threshold values of all code analysis rules: now the threshold value is included in the range of allowed values.
