EiffelStudio 20.05.x Releases

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

20.05._._ (../../2020, beta 20.05)

New features

  • EiffelStudio: Added the new Wrap_c tool.
  • EiffelStudio: Added command line option -reset_ide_layout to reset the IDE layout (mostly docking setting for now, usually to recover from bad crash).
  • 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).


  • 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.
  • library (base): There are now 2 more class aliases: IMMUTABLE_STRING and READABLE_STRING.
  • 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.

Libraries Improvements

  • library (sqlite3): Updated SQLite3 C code to version 3.31.1 - 2020-01-27.
  • library (eiffelweb): Improved web form html generation, especially for select and type checkbox
  • library (smarty): Added support for manifest string in condition, such as {if expression="$foo ~'bar'"} ...{/if} .
  • library (cms): improved database connection, and error handling during connection.
  • 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.
  • library (base): Moved built-in routines to ISE_RUNTIME, and also from WEL_IDENTIFIED to IDENTIFIED_ROUTINES.
  • library (base): Added support for simpler Unicode output in the console based on new PLAIN_TEXT_FILE.put_string_32.
  • library (cms): Improved authentication implementation.

New libraries

Multiple new wrappers for C libraries:

  • 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_quirc : Quirc is a C library for scanning QR codes.
  • wrap_lz4 : Extremely fast compression library.
  • wrap_libqrencode : Libqrencode is a fast and compact library for encoding data in a QR Code, a 2D symbology that can be scanned by handy terminals such as a smartphone. The capacity of QR Code is up to 7000 digits or 4000 characters and has high robustness.
  • 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.

Features removed

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): Marked {READABLE_STRING_GENERAL}.plus as obsolete to avoid potential data loss when precondition of the feature is not maintained.
  • library (base): Renamed {READABLE_STRING_GENERAL}.plus in descendants and added sized variants of feature plus to sized variants of strings.
  • Added the following implicit conversions:

Developer changes

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