EiffelStudio 18.05.x Releases

Beta download: https://ftp.eiffel.com/pub/beta/18.05/

18.05.x.y

New features

• compiler: Supported extension of project targets from a different project (ECF).
• EiffelStudio: added auto-import (and auto-export) for the execution parameters using the file $target_name.$system_name.dbg.profiles.xml located in same folder as the .ecf file.
• compiler: allow target to extend a target from another .ecf <target name="foo" extends="bar" extends_location="another.ecf"> ....
• compiler: added support to ecf condition with custom value comparisons based on case-sensitive, case-insensitive, regular expression and wildcard.
• debugger: the string display debugger viewer includes information about current caret position.
• debugger: added a json debugger viewer (similar to the xml viewer).
• EiffelStudio: the address bar (class and feature field in the tool bar) now supports arrow up and down, to see next or previous suggestions, and also "Ctrl+Space" to open the completion dialog.

Improvements

• eweasel: Supported Unicode in paths, arguments and environment.
• code analyzer: test#codeanalysis027 — Supported more expressions when checking for CA071 (comparison to itself): Result, Current, Precursor, non-object call.
• code analyzer: test#codeanalysis027 — Supported object (tilde) equality when checking for CA071 (comparison to itself).
• code analyzer: test#codeanalysis028 — Supported conditional expressions when checking for CA046 (inequality used in if-then-else-end) in addition to conditional instructions.
• EiffelStudio: Supported localized output from precompilation process (in case EiffelStudio is started in the environment with a non-English locale).
• compiler: Reported source code context for class-level errors when this information is available.
• compiler: Taken a condition into account when processing a precompile to allow for using different precompiles with different settings and for making such uses optional.
• code analyzer: test#codeanalysis029 — Extended the rule CA017 (an empty conditional) to check for an empty compound after elseif or else parts.
• compiler: Changed rules for class features. Now any non-static external and constant feature automatically gets a class postcondition if there are no explicit contracts. Redeclaration into or merging with a class feature requires a precursor either to be a class feature or to have no contracts.
• EiffelStudio: Indicated whether a feature is a class one with special icons in various tools.
• library: Marked many features of Base library as class ones to make them usable for non-object calls.
• EiffelStudio: improved auto completion for "|." and ".." cases.
• library: added EXECUTION_ENVIRONMENT.available_cpu_count

Feature removed

• compiler: Removed an unused setting msil_assembly_compatibility from ECF (Eiffel configuration file).

Bug fixes

• compiler: Fixed issues that caused link errors when using run-time in DLL (rather than statically linked).
• code analyzer: test#codeanalysis027 — Avoided reporting expressions involving computation (e.g. function calls) by CA071 (comparison to itself).
• code analyzer: test#codeanalysis028 — Avoided false positives for CA046 (inequality used in if-then-else-end) when elseif parts are present.
• EiffelStudio: Disabled editing read-only library settings.
• compiler: bug#17297, test#valid255 — Supported detection of VHPR(5) violations for arbitrary ancestors, not just for immediate parents. Breaking change for classes that inherit different generic derivations of the same class.
• compiler: test#valid255 — Fixed a recompilation issue when first compilation fails and parents of the classes are changed.
• code analyzer: test#codeanalysis029 — Avoided false positives for CA017 (an empty conditional) when there are non-empty elseif or else parts.
• compiler: Specified source code class when reporting VUCR to show source code correctly.
• library: bug#19436 (test#utf003) — Fixed several issues in the implementation of UTF_CONVERTER.is_valid_utf_16 (premature end of validation, infinite looping on certain inputs, access on index outside valid bounds).
• library: Fixed a bug in the implementation of {WEL_API}.cwin_read_file and {WEL_API}.cwin_write_file that may cause GC in multi-threaded environment to hang on Windows because ReadFile and WriteFile were not marked as blocking.
• EiffelStudio: Made sure message counters in the error panel are updated when messages are removed by a user.
• library: test#thread024 - Fixed a bug in the implementation of PROCEDURE and FUNCTION classes that might cause memory corruption, access on void target or access on an invalid address when using agents in a system with any concurrency option turned on.
• EiffelStudio: Fixed Pick and Drop from `Precursor` tokens.

User changes

• EiffelStudio: in the completion window, complete code with a single click action, and show tooltip when mouse is over the entry.
• EiffelStudio: show auto completion window, even if there is a unique entry.

Developer changes

• eweasel: Ignored end-of-line differences when comparing output files.
• compiler: Updated configuration file (ECF) schema version.
