The first implementation of the WEAK_REFERENCE class is now available only for classic mode. Support of type checking of separate entities for SCOOP was added although there is not yet support for code generation. An optimization of {SPECIAL}.fill_with and {SPECIAL}.force was implemented making those calls much faster. On Windows platform, we are now using gcc version 4.4.5 on both 32 and 64-bit system. Some incrementality, Unicode parsing, once per objects and various other bugs have been fixed.... read more

EiffelStudio 6.7.8.4135 released

Added a new tracing facility that can call back Eiffel code each time the code enter/exit a routine.

Otherwise, this is mostly a bug fix release with some incrementality bugs fixed. See http://dev.eiffel.com/EiffelStudio_6.7_Releases for more details.

EiffelStudio 6.6 released

We are pleased to announce the release of EiffelStudio 6.6. You will find below a summary of what 6.6 brings.

Happy Eiffeling,
The EiffelStudio Team

== What's new ==
* EiffelStudio: Added the parent clauses of a class in the "Features tool" making it easier to navigate/edit parent classes.
* Compiler: Added support for new once syntax and once per object.
* Compiler: Added support for RAT/QAT, with the following limitations:
- Qualified anchored types that involve formal generics with multiple constraints are not supported.
- Creation and object tests with the type depending on qualified anchored types that involve deferred intermediate types are not supported on .NET.
* Compiler: Added a new option Total Order on REALs which let you have NaN equal to NaN and NaN being the smallest number of all. This option is disabled by default as it could break existing code. The rationale for this option is to have contracts work properly when manipulating the NaN value and not getting spurious contract violation.
* Compiler: Added the ability to version a class for storable. It is done via the note clause of a class, i.e. note storable_version: tag. When the storing and retrieving system have a different version a mismatch is triggered even if they look to have the same content.
* Compiler: Supported new variant of a check instruction that is not subject for assertion monitoring settings (in other words the check cannot be turned off) and can be used to introduce a new void safe scope of a read-only or object test local:
check Assertion then
Compound
end
* AutoTest: Added tool for displaying the result details of a single test execution.
* AutoTest: Added tool for comparing the current testing results to a previously exported set of results, highlighting tests for which the latest execution revealed a different result.
* AutoTest: Changed AutoTest Tool to store testing results permanently, and added the ability to export results to a text file.
* Libraries: Added ability to traverse most containers in EiffelBase using the new iteration (across) form of the loop construct.
* Libraries: Added a new feature trim to the RESIZABLE class and its decendants to allow for minimizing the allocated storage.
* Libraries: Added support for correct mismatch in the SED serialization cluster.... read more

EiffelStudio 6.6.8.2484 released

A new project setting option has been added: Total Order on REALs which lets you have NaN equal to NaN and NaN being the smallest number of all. This option is disabled by default as it could break existing code. The rationale for this option is to have contracts work properly when manipulating the NaN value and not getting spurious contract violation.

To help users managing their storable files, we have added the ability to version a class. It is done via the note clause of a class, i.e. note storable_version: tag. When the storing and retrieving system have a different version a mismatch is triggered even if they look to have the same content.... read more

EiffelStudio 6.6.8.2214 released

This is the first pre-release of EiffelStudio 6.6.

We added a new construct: the `check' statement which can be useful in void-safe mode which is like a check compound except that even if assertions are disabled and the assertion is false, you still get a check violation.

We have redone our runtime multithreading and solved a few synchronization issues when threads have a very short lifespan and that you create many of them. Also we have prevented some deadlock in the runtime if a thread is killed outside the Eiffel environment. ... read more

EiffelStudio 6.5 released

This is the final release of EiffelStudio 6.5. This version fixes some issues with STRING not updating its hashcode in `remove_substring', a C compilation error after a finalization, some various issues with AutoTest and the debugger. Fixed a CECIL issue and a compatibility issue with old storables that could not be retrieved in 6.5.

EiffelStudio 6.5.8.1483 released

This is the release candidate for EiffelStudio 6.5. This version adds compiler support for the new loop construct although no library support has been added yet. Numerous compiler bugs have been fixed: proper handling of attached type in conversions, compile time catcall checker crash, creation of manifest arrays in void-safe mode triggering a precondition violation, full type checking issues, proper code generation for `{ANY}.generating_type' in experimental mode under .NET, proper retrieval of SPECIAL objects in experimental mode. Some issues with the saving/restoring of EiffelStudio layout were fixed.... read more

EiffelStudio 6.5.8.945 released

This is a major bug fix release (about 200 bugs have been fixed since the last intermediate release). In addition, we have added the "+" operator to READABLE_STRING_GENERAL, removed the need for the `wel_hook.dll' for pick and drop in all vision2 applications on Windows.

EiffelStudio 6.5.8.524 released

The EiffelBase extension library was added to the EiffelStudio delivery. This library provides a new class SEARCH_TABLE which is basically a set where items are HASHABLE, and some new sorting facilities for classes descendants of INDEXABLE. A few assertion violations and infinite loops with PART_SORTED_SET and BINARY_SEARCH_TREE_SET were fixed. Various EiffelStudio bugs were fixed. `clear_all' in STRING classes and HASH_TABLE has been made obsolete in favor of `wipe_out'. A behavior change in STRING.resize was done which prevents from calling `resize' with a size smaller than the current size of the string. Simplify automatic licensing of Eiffel classes by simply having a license.lic file next to the Eiffel Configuration File (ECF).... read more

EiffelStudio 6.5.8.294 released

Added the ability to see the C compilation warnings/errors in the error list of EiffelStudio (instead of just seeing a generic C compilation error). Changed a few things in AutoTest (the new name of the Eiffel Testing Framework). Changed the return type of `generating_type' in ANY from STRING_8 to TYPE [like Current]; existing code should still compile thanks to a conversion from TYPE to STRING_8. Fixed a lot of small bugs reported over the year by users.... read more

EiffelStudio 6.4 released

A new major milestone of EiffelStudio is now available for download. This version includes new version of our libraries that are void-safe; due to the breaking changes they might bring, they are not yet the default. To use them, you have to use the experimental version of EiffelStudio.

You can find more about the 6.4 release at:

EiffelStudio 6.4.7.9263 released

6.4 Release Candidate. For backward compatibility issue we are including 2 versions of the libraries. By default it will use the backward compatible version. To use the new library, you have to use the `-experiment' switch. It is possible to create code that compiles against both versions as long as some little changes are brought to the code.
