  • library (base): Added READABLE_STRING and IMMUTABLE_STRING as aliases to sized versions of string classes.
  • compiler: Supported a mapping from STRING (and variations) to STRING_32 (and variations).
  • compiler: Supported multi-branch expressions that are similar to multi-branch instructions, but Then_parts and Else_part contain expressions instead of instruction sequences.

Improvements

  • EiffelStudio: Added Unicode support in the editor search facilities.
  • EiffelStudio: Improved account sign in solution.
  • tools (eiffel): Improved detection of application targets.
  • compiler (code analyzer): Avoided false positives for unneeded parentheses around expressions (CA023).
  • library (base): Updated character properties to use Unicode 13.0.0.
  • library: Updated some libraries to be compilable when STRING (and variants) is mapped to STRING_32 (and variants): base, base_extension, time, base_process, process, net, diff, wel, testing.
  • library (base): Added Unicode aliases for existing features in classes BOOLEAN, COMPARABLE, NUMERIC and their descendants.
  • compiler: Changed evaluation of untyped manifest strings to treat them as being of type STRING_32 if they contain characters with code points above 255.

  • library (wikitext): Updated wikitext xhtml generator to follow recommendations from https://validator.w3.org/
  • library (curl): Updated cURL binaries using static linking of Microsoft's C RunTime (CRT) to avoid dependency on vcruntime140.dll.

New libraries

  • Multiple new wrappers for C libraries:
Wrapper Description of C library
wrap_yaml LibYAML is a YAML parser and emitter library.
wrap_sdl Simple DirectMedia Layer is a cross-platform development library designed to provide low-level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. It is used by video playback software, emulators, and popular games including Valve's award-winning catalog and many Humble Bundle games.
wrap_libusb libusb is a C library that provides generic access to USB devices. It is intended to be used by developers to facilitate the production of applications that communicate with USB hardware. It is portable: Using a single cross-platform API, it provides access to USB devices on Linux, macOS, Windows, etc.

wrap_libgit2 libgit2 is a portable, pure C implementation of the Git core methods provided as a re-entrant linkable library with a solid API, allowing you to write native speed custom Git applications in any language which supports C bindings.
wrap_gsl The GNU Scientific Library (GSL) is a collection of routines for numerical computing.
wrap_tidy Libtidy is a C static and dynamic library that developers can integrate into their applications in order to bring all of HTML Tidy's power to your favorite tools. libtidy is used today in desktop applications, web servers, and more.

Bug fixes

  • EiffelStudio: When forcing the reload of current editor (Ctrl-R), open a confirmation dialog if file is modified.
  • EiffelStudio: Fixed display of variables and type mappings in project settings.
  • EiffelStudio: Improved the code completion popup dialog (filter, Unicode, ...)
  • library (feed): Improved RSS2 and ATOM implementation for validation.
  • library (xml): Escape any non ASCII character.
  • compiler: test#final134 — Fixed a bug that may cause memory corruption in finalized mode when a feature with an argument of a reference type has a single instruction with a single call which is instance-free and uses the argument.
  • compiler: test#exec347 — Fixed a bug that might cause memory corruption or a crash if the application uses a feature argument as an anchor without using the argument value.
  • EiffelStudio: Fixed bugs causing clickable formats to report an error when restricted or symbolic forms of loops are used.
  • EiffelStudio: Fixed rendering of symbolic forms of loops in a clickable format and stepping through them in the debugger.
  • compiler: bug#19647 (test#attach129) — Fixed a bug that might cause a self-initializing attribute of an attached type to remain void if it is not properly set by a creation procedure, has body, and the body does not set result to non-void value.
  • compiler: bug#19637 (test#syntax075) — Fixed a bug that prevented from using multiple feature aliases in renaming.
  • compiler: Fixed a potential bug when a wrong type can be computed for tuples, arrays, conditional and multi-branch expressions with mutual nesting.

Features removed

  • library (base): Marked {READABLE_STRING_GENERAL}.plus as obsolete to avoid potential data loss when precondition of the feature is not maintained.

User changes

  • library (base): Changed behavior of {CHARACTER_8}.to_lower and {CHARACTER_8}.to_upper (as well as versions for CHARACTER_8_REF), as well as property queries, to interpret characters with codes 128-255 according to ISO 8859-1.
  • library (base): Renamed {READABLE_STRING_GENERAL}.plus in descendants and added sized variants of feature plus to sized variants of strings.
  • library (base): Added the following implicit conversions:
    • IMMUTABLE_STRING_8 → READABLE_STRING_32;
    • IMMUTABLE_STRING_GENERAL → IMMUTABLE_STRING_32, READABLE_STRING_32, STRING_32;
    • READABLE_STRING_GENERAL → IMMUTABLE_STRING_32, READABLE_STRING_32, STRING_32;
    • STRING_GENERAL → IMMUTABLE_STRING_32.
  • compiler: Changed the list of expressions that are allowed to be used in object tests without an explicit type, e.g. Current cannot be used anymore, because it is always attached and most probably such an expression indicates an error, and allowed to use any expression in an object test as soon as there is an explicit type.

Developer changes

  • library(curl): better error message.
  • library(curl): added SFTP example.
  • library(gobo): updated to Gobo 19.11
