= Roadmap for second release, as early as possible in 2011 =

* fix local installation
5 6 7 8 9
** fix local executables names (DONE)

* fix problems with .why.conf
** if we distribute the current state, users who already have a ~/.why.conf
will get a error message because of missing loadpath to modules
10 11
     Done? - the magic number will force to not use the old ~/.why.conf of
             the user
12 13
** generally speaking, we should rethink the design of that .why.conf: avoid
   absolute paths,
14 15
   Partially done - libdir, datadir, loadpath, ... are not written in why.conf
   if they correspond to the default value.

== Mails announcement ==

----------------------- 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
136
from Why versions 2.xx.
Andrei Paskevich's avatar

Andrei Paskevich committed

The home web page of Why3 is http://why3.gforge.inria.fr, where you

can find the source distribution and the manual. See the manual for 
installation instructions and contact information.

The main new features with respect to Why 2.xx are the following.
MARCHE Claude's avatar
MARCHE Claude committed
143 144 145 146

1) Completely redesigned input syntax for logic declarations

* new syntax for terms and formulas
Andrei Paskevich's avatar
roadmap  
Andrei Paskevich committed
147 148 149
* enumerated and algebraic data types, pattern matching
* recursive definitions of logic functions and predicates,
  with termination checking
MARCHE Claude's avatar
MARCHE Claude committed
150
* inductive definitions of predicates
Andrei Paskevich's avatar
roadmap  
Andrei Paskevich committed
151 152
* declarations are structured in components called "theories",
  which can be reused and instantiated
MARCHE Claude's avatar
MARCHE Claude committed
153 154 155 156 157 158 159

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

3) Source code organized as a library with a documented API,
MARCHE Claude's avatar
MARCHE Claude committed
161
to allow access to Why3 features programmatically.

162 163 164 165 166 167 168 169 170 171 172 173 174 175 176

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
* ability to edit proofs for interactive provers (Coq only for the moment) 
  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:
MARCHE Claude's avatar
MARCHE Claude committed

* 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).
MARCHE Claude's avatar
MARCHE Claude committed
182 183 184 185

* 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

186 187 188 189 190 191 192 193
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
202
from Why. The detailed announcement is attached below.

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
and process the generated Why3 file "<file>.jessie/why/<file>_why3.why" 
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
219
* ability to call Coq on a given VC to provide a proof script. Incidentally,
MARCHE Claude's avatar
MARCHE Claude committed
220 221 222 223 224 225 226 227 228 229
  this feature can be used to analyse the VC to understand why it is
  not proved automatically.  
* 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.
