electrod 0.1.4 · OCaml Package

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

type raw_goal = (Raw_ident.t, Raw_ident.t) GenGoal.t

type raw_block = (Raw_ident.t, Raw_ident.t) GenGoal.block

type raw_problem = {

file : string option;
raw_univ : raw_urelements list;
raw_decls : raw_declaration list;
(*
does not contain 'univ'
*)
raw_goal : raw_goal;
raw_invar : raw_block;
(*
may be empty
*)
raw_inst : raw_assignment list;
(*

*)
raw_syms : raw_symmetry list;
(*

}

and raw_urelements = private

| UIntvl of raw_interval
| UPlain of Raw_ident.t

and raw_declaration = private

| DConst of Raw_ident.t * int option * raw_scope
| 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).

and raw_multiplicity = [ `Lone | `One ] option

and raw_scope = private

| SExact of raw_bound
| SInexact of raw_bound * raw_multiplicity * raw_bound

and raw_bound = private

| BUniv
| BRef of Raw_ident.t
(*
reference to a previously-defined set
*)
| BProd of raw_bound * raw_multiplicity * raw_bound
(*
None/Some (lone/one)
*)
| BUnion of raw_bound * raw_bound
| BElts of raw_element list

and raw_element = private

| EIntvl of raw_interval
(*
1-tuples
*)
| ETuple of raw_tuple

and raw_tuple = Raw_ident.t list

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

and raw_interval = Raw_ident.t * Raw_ident.t

and raw_assignment = Raw_ident.t * raw_tuple list

asignemnt of tuples to a relation

may be empty

and raw_symmetry =
  (Raw_ident.t * raw_tuple) list * (Raw_ident.t * raw_tuple) list

type raw_paragraph =

| ParGoal of raw_goal
| ParInst of raw_assignment list
| ParSym of raw_symmetry list
| 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 Parser_main for more information).)
