Module Coqlib

Indirection between logical names and global references.

This module provides a mechanism to bind “names” to constants and to look up these constants using their names.

The two main functions are register_ref n r which binds the name n to the reference r and lib_ref n which returns the previously registered reference under name n.

The first function is meant to be available through the vernacular command Register r as n, so that plug-ins can refer to a constant without knowing its user-facing name, the precise module path in which it is defined, etc.

For instance, lib_ref "core.eq.type" returns the proper GlobRef.t for the type of the core equality type.

val register_ref : string -> Names.GlobRef.t -> unit

Registers a global reference under the given name.

val lib_ref : string -> Names.GlobRef.t

Retrieves the reference bound to the given name (by a previous call to register_ref). Raises an error if no reference is bound to this name.

val has_ref : string -> bool

Checks whether a name refers to a registered constant. For any name n, if has_ref n returns true, lib_ref n will succeed.

val check_ind_ref : string -> Names.inductive -> bool

Checks whether a name is bound to a known inductive.

val get_lib_refs : unit -> (string * Names.GlobRef.t) list

List of all currently bound names.

DEPRECATED

val find_reference : string -> string list -> string -> Names.GlobRef.t

find_reference caller_message [dir;subdir;...] s returns a global reference to the name dir.subdir.(...).s; the corresponding module must have been required or in the process of being compiled so that it must be used lazily; it raises an anomaly with the given message if not found

val coq_reference : string -> string list -> string -> Names.GlobRef.t

This just prefixes find_reference with Coq...

val gen_reference_in_modules : string -> string list list -> string -> Names.GlobRef.t

Search in several modules (not prefixed by "Coq")
