Attention une mise à jour du service Gitlab va être effectuée le mardi 18 janvier (et non lundi 17 comme annoncé précédemment) entre 18h00 et 18h30. Cette mise à jour va générer une interruption du service dont nous ne maîtrisons pas complètement la durée mais qui ne devrait pas excéder quelques minutes.

      Reworking tags and transformations, stage 3: · dd3aac24
      Andrei Paskevich authored
      - everything is converted to the new shiny way of doing things.
        Well, everything except Gappa, which seems very unifinished anyway,
        and Encoding_instantiate, which is too complex and would like to 
        update it with François.
      Also, I commented a little piece of exception reporting in manager/,
      will see it with Claude.
      Please inform me about any bugs, ugly APIs, and proposed corrections.
      All the non-implemented things, mentioned in the previous commit
      message are still in the TODO list and will be done soon.

      Reworking tags and transformations, stage 2: · 157f4a5c

      - dependent transformations (ones that depend on cloning history
        and/or metaproperties) have now the same type Trans.trans and
        can be registered via Trans, too.
      - load_driver accumulates appropriate tdecls to be appended to
        tasks before transformation/printing.
      At this moment, we have almost everything in place and are ready
      to remove Register module (subsumed by Trans and Printer in core/)
      and Prover module (its functions will move to Driver), and convert
      all printers and transformations to use the new infrastructure. 
      Not implemented yet:
      - appending driver-imposed tdecls to tasks - when and where?
      - metas-options - what is the best way to implement them?
      - syntax/typing for metas in theories and drivers.

      - introduce a new Theory.tdecl "Meta" to be used for tags
      - simplify cloning procedure, get rid of the th_clone field
      - when a goal proposition is discarded during cloning, 
        it's still keeped in the theory as a "skip proposition",
        this is needed to preserve/clone every local identifier.
        Skip propositions are eliminated during task formation.
      - get rid of a separate Task.tdecl type
      - reorganize the Task.task_hd record:
        * use/clone history is cached in a theory-keyed map;
        * meta-properties are cached in a tagname-keyed map.
        This is done to simplify the fine-grained configuration
        of transformations.

      rewrite the command line treatment to provide reasonable · 77f29212
      Andrei Paskevich authored
      default actions in case explicit options are missing.
      The command line has the following structure:
          why [options] [[file|-] [-t <theory> [-g <goal>]...]...]...
          Qualified theories come from the library, not from file.
          When the driver is not specified, pretty-print theories.
          When neither --prove nor --output are given, print tasks.
          When no theory is specified for a file, use every theory.
          When no goal is specified for a theory, use every goal.
          % why.opt
          [shows usage information]
          % why.opt test.why
          [prints the contents of test.why]
          % why.opt -t int.Int
          [prints the library theory int.Int]
          % why.opt -D drivers/z3.drv test.why
          [sends every task from test.why to stdout]
          % why.opt -D drivers/z3.drv -o directory test.why
          [creates ./directory/ if it's does not exist and
           sends every task to a separate file in ./directory/]
          % why.opt -D drivers/z3.drv --prove test.why -t ThA
          [calls the prover for every goal from theory ThA in test.why]
          % why.opt -D drivers/z3.drv --prove test.why -t ThA -g G1 -g G2
          [calls the prover for G1 and G2 from theory ThA in test.why]
          % why.opt -D drivers/z3.drv -t int.Abs -g G1 test.why -t ThA
          [prints G1 from int.Abs and every goal from ThA in test.why]
