Module Dolmen_std.Id

Standard implementation of identifiers

Type definitions

type namespace =
  1. | Var
    (*

    Namespace for variables. Not all variables are necessarily in this namespace, but ids in this namespace must be variables.

    *)
  2. | Sort
    (*

    Namepsace for sorts and types (only used in smtlib)

    *)
  3. | Term
    (*

    Most used namespace, used for terms in general (and types outside smtlib).

    *)
  4. | Attr
    (*

    Namespace for attributes (also called annotations).

    *)
  5. | Decl
    (*

    Namespace used for naming declarations/definitions/statements...

    *)
  6. | Module of string
    (*

    Namespaces defined by modules (used for instance in dedukti).

    *)
type t = {
  1. ns : namespace;
  2. name : string;
}

The type of identifiers, basically a name together with a namespace.

Implemented interfaces

include Dolmen_intf.Id.Logic with type t := t and type namespace := namespace
val sort : namespace

The namespace for sorts (also called types). Currently only used for smtlib.

val term : namespace

The usual namespace for terms.

val attr : namespace

Namespace used for attributes (also called annotations) in smtlib.

val decl : namespace

Namespace used for declaration identifiers (for instance used to filter declarations during includes)

val mod_name : string -> namespace

Namespace used by modules (for instance in dedulkti).

Usual comparison functions

val hash : t -> int
val equal : t -> t -> bool
val compare : t -> t -> int

Usual functions for hashing, comparisons, equality.

Additional functions

val mk : namespace -> string -> t

Create an identifier.

val full_name : t -> string

Returns a full name for the identifier. NOTE: full names may not be unique and therefore not suitable for comparison of identifiers.

val pp : Buffer.t -> t -> unit
val print : Format.formatter -> t -> unit

Printing functions.

Standard attributes

val rwrt_rule : t

The tagged term is (or at least should be) a rewrite rule.

val tptp_role : t

The tagged statement has a tptp role. Should be used as a function symbol applied to the actual tptp role.
