* Realisation Coq
* tool why3session avec -latex, -html, -stats, etc
* tool why3doc
* several versions of the same prover
* Improved IDE: left scrollbar, font enlargement, etc.

TODOS:

* Documentation
** GM Realisations Coq, comment fait l'utilisateur pour faire ses realisations
   ne pas oublier de dire que les dependances avec le .why ou .mlw: ne sera pas vérifié
** ??? revoir documentation du smoke detector
** Documenter l'utilisation de plusieurs version du meme prouveur comme CVC3 et Z3
** CLAUDE Documenter les popups qui peuvent apparaitre dans why3ide quand les prouveurs ont changé
   ET LES METTRE AU POINT
*** ANDREI ajouter option a why3config pour ajouter association ident-executable
*** CLAUDE meme ordre d'idee: ne pas ecraser "default editor" et "timelimit"
** complete api.tex: explain how to build theories, apply
   transformations, write new functions on terms (A)
** complete manpages.tex: section "Drivers of external provers" (A+F)
** make the glossary available

* CM why3session
** passe sur la documentation ecrite par Francois reecrite par Guillaume
** option -latex et -html deplacé de why3replayer vers why3session
** reprendre une partie de src/ide/stats.ml, et virer executable why3stats

** CLAUDE Ensure that we kill a prover after some time (ressurect %T ? with a
MARCHE Claude's avatar

----------------------- Why-discuss list ---------------------------

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
MARCHE Claude's avatar
MARCHE Claude committed
394
from Why versions 2.xx.
Andrei Paskevich's avatar
Andrei Paskevich committed
395 396

The home web page of Why3 is http://why3.gforge.inria.fr, where you
397
can find the source distribution and the manual. See the manual for
MARCHE Claude's avatar

The main new features with respect to Why 2.xx are the following.
MARCHE Claude's avatar
MARCHE Claude committed
401 402 403 404

1) Completely redesigned input syntax for logic declarations

* new syntax for terms and formulas
Andrei Paskevich's avatar
Andrei Paskevich committed
405 406 407
* enumerated and algebraic data types, pattern matching
* recursive definitions of logic functions and predicates,
  with termination checking
MARCHE Claude's avatar
MARCHE Claude committed
408
* inductive definitions of predicates
Andrei Paskevich's avatar
Andrei Paskevich committed
409 410
* declarations are structured in components called "theories",
  which can be reused and instantiated
MARCHE Claude's avatar
MARCHE Claude committed
411 412 413 414 415 416 417

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

Andrei Paskevich's avatar
Andrei Paskevich committed
418
3) Source code organized as a library with a documented API,
MARCHE Claude's avatar
MARCHE Claude committed
419
to allow access to Why3 features programmatically.
MARCHE Claude's avatar
MARCHE Claude committed
420 421 422 423 424 425

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
426
* ability to edit proofs for interactive provers (Coq only for the moment)
MARCHE Claude's avatar
MARCHE Claude committed
427 428 429 430 431 432 433 434
  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
Andrei Paskevich's avatar

  and intentionally undocumented in the current documentation (the input
  syntax for programs may change a lot in the future).
MARCHE Claude's avatar
MARCHE Claude committed

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.

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
469
and process the generated Why3 file "<file>.jessie/why/<file>_why3.why"
