Module Libelectrod.RawSource

Type for "raw" ASTs yielded by the Electrod parser.

Sourcetype raw_problem = {
  1. file : string option;
  2. raw_univ : raw_urelements list;
  3. raw_decls : raw_declaration list;
    (*

    does not contain 'univ'

    *)
  4. raw_goal : raw_goal;
  5. raw_invar : raw_block;
    (*

    may be empty

    *)
  6. raw_inst : raw_assignment list;
    (*

    may be empty

  1. | UIntvl of raw_interval

Sourceand raw_declaration = private
  1. | DConst of Raw_ident.t * int option * raw_scope
  2. | DVar of Raw_ident.t * int option * raw_scope * raw_scope option

The int option is the optionally-declared arity (compulsory for an empty scope).

  2. | BRef of Raw_ident.t

  2. | ETuple of raw_tuple
Sourceand raw_tuple = Raw_ident.t list

A n-tuple (incl. n = 1). inv: nonempty list

Sourceand raw_interval = Raw_ident.t * Raw_ident.t
Sourceand raw_assignment = Raw_ident.t * raw_tuple list

asignemnt of tuples to a relation

may be empty

Sourceand raw_symmetry = (Raw_ident.t * raw_tuple) list * (Raw_ident.t * raw_tuple) list
Sourcetype raw_paragraph =
  1. | ParGoal of raw_goal
  2. | ParInst of raw_assignment list
  3. | ParSym of raw_symmetry list
  4. | ParInv of raw_block

This definition is here just to be used in the parser ((to avoid cyclic dependencies). The puprose of paragraphs is to deal easily and efficiently with permutation of these (see Parse_main for more information).)
