      Rework numerical constants. · d3d7c7ac
      Guillaume Melquiond authored
      Main changes are:
      - Real constants now offer a normalized representation usable for internal
        computations.
      - Constants are no longer stored in textual form.

      Add the ability to · f0547868
      Clément Fumex authored
      * declare range types and float types,
      * use integer (resp. real) literals for those types through casting,
      * specify how to print them in drivers.
      
      Change in syntax
      * use
      
        type t = < range 1 2 >   (* integers from 1 to 2 *)
        type t' = < float 4 12 > (* float with 4 bits in exponent and 12 in mantissa *)
      
        the two projections :
        t'int
        t''real
      
        and the predicate :
        t''isFinite
      
      * Restrict the use of "'" in whyml:
        Users are not allowed to introduce names where a quote symbol
        is followed by a letter. Thus, the following identifiers are
        valid:
      
        t'
        toto'0''
        toto'_phi
      
        whereas toto'phi is not.
      
      Note: we do not yet support negative numbers in range declaration
      and casting of a literal.

      escape special XML characters in Isabelle's VCs · a8d40652
      Piotr Trojanek authored
      With the recent Isabelle realization of reals some altname attributes
      were printed with characters that must be escaped in a valid XML output;
      this was tested with xmllint.

      Tuned printing of theory names · d441d6a3
      Stefan Berghofer authored
      Theory names are assumed to be unique with respect to their path.
      Therefore, do not attempt to disambiguate them, which should result
      in more readable / predictable names.

      Task: use "Use" to represent theory use · d993dad4
      Andrei Paskevich authored
      up to this point, we used Clone declarations with an empty substitution
      to represent use of theories in tasks. The intention was to stress the
      fact that the imported declarations are physically present in the task
      and thus are followed by a "witness" Clone declaration (whereas a Use
      inside a theory acts rather as a pointer to follow).
      
      However, this encoding requires the clone substitution to cover every
      locally defined symbol: otherwise we might not be able to distinguish
      a use from a clone. Therefore, we had to clone even Pgoal propositions
      as Pskip, in order to keep the substitutions complete.
      
      This commit restricts the Clone declarations in tasks to actual
      theory cloning, and represents theory use with Use declarations.
      This hopefully makes the API more clear, and will allow us to
      abolish Pskip.
