* Logic language
 - support for higher-order logic
 - rename andb, orb, xorb and notb into and, or, xor and not

* more libraries (theories and modules)

* A true Jessie3 front-end

* Why3ML
 - Fast WP a la Leino
 - assert qui ne donne pas une hypothese dans la suite -> "check"
   also: in a black box

* Add more examples in the regression tests and in the proval gallery

* A literate programming tool for Why3 (JCF)


* IDE:
 - edition, navigation (partially done)
 - saving session: add shortcut "ctrl-S", but beware of confusion with saving the input file
 - reimplement "hide proved goals" feature
  + suggested solution: replace model + filter_model by a custom model
  (JC + ?)
 - restore provers detection in the middle of a session.
 - commentaires dans les sessions, attachés a chaque ligne

   . Lors d'un replay, le dialogue "replace proof" apparait un nombre important de fois,
     il faut absolument pouvoir interrompre, ou donner une reponse qui soit appliquée pour le reste.
     (le 3e bouton "never replace..." ne semble pas jourer ce role...)
   . le dialogue "replace proof" est de toute facon trop large, et les choix possibles sont confus.

We are happy to announce the first public release of Why3, also known
as the Why platform next generation. It is a new project, independent

The main new features with respect to Why 2.xx are the following.

1) Completely redesigned input syntax for logic declarations

* new syntax for terms and formulas

* enumerated and algebraic data types, pattern matching
* recursive definitions of logic functions and predicates,
  with termination checking

  which can be reused and instantiated

2) More generic handling of goals and lemmas to prove

* concept of proof task
* generic concept of task transformation
* generic approach for communicating with external provers

3) Source code organized as a library with a documented API,

450
to allow access to Why3 features programmatically.

4) GUI with new features w.r.t. the former GWhy

* session save and restore
* prover calls in parallel
* splitting, and more generally applying task transformations, on demand
457
* ability to edit proofs for interactive provers (Coq only for the moment)

458 459 460 461 462 463 464 465
  on any subtask

5) Extensible architecture via plugins

* users can define new transformations
* users can add connections to additional provers

Beware that some Why features are not yet available in Why3:

* There is a VC generator distributed in Why3 in an experimental stage

  and intentionally undocumented in the current documentation (the input
  syntax for programs may change a lot in the future).

471 472 473 474

* There is no front-end for other languages like C or Java. However,
  the last release Why 2.28 is able to use Why3 as a back-end

Notice that Why3 is expected to replace Why2 in the future. As such,
it is the project where improvements and new features will be
implemented. As this is the first public release of Why3, it is likely
that missing features, and possibly bugs, will raise soon. Please
report those in the bug tracker, we will do our best to fix them and
provide new releases in a short time.

--------------------- Frama-C list ----------------------------


The first release of Why3, also known as the Why platform next
generation, is publicly available. Why3 is a new project, independent
MARCHE Claude's avatar
MARCHE Claude committed
491
from Why. The detailed announcement is attached below.

492 493 494 495 496 497 498 499

The Jessie plugin of the Why release 2.28 has the ability to use Why3
as back-end. You must install both Why 2.28 and Why3 for this to work.

Using the Why3 GUI on a C file is done as follows
  frama-c -jessie -jessie-atp why3ide <file>.c
(You can also run it in batch mode using
  frama-c -jessie -jessie-atp why3 <file>.c
500
and process the generated Why3 file "<file>.jessie/why/<file>_why3.why"

501 502 503 504 505 506 507
with Why3 batch tools).

The main new features of interest in the GUI are

* new provers available
* calling provers in parallel
* splitting on demand
MARCHE Claude's avatar
MARCHE Claude committed
508
* ability to call Coq on a given VC to provide a proof script. Incidentally,
MARCHE Claude's avatar
MARCHE Claude committed
509
  this feature can be used to analyse the VC to understand why it is
510
  not proved automatically.

511 512 513 514 515 516 517 518
* proof session saved and restored at startup

Any question, remark or bug report concerning only Why3 should be done
using the Why3 public discussion list and bug tracker.
