Nametab (u.4b72d9d53197f808b005effa2cda4f29.coq-core.8.20.1.doc.coq-core.library.Nametab)

These globalization tables associate internal object references to qualified names (qualid). There are three classes of names:

1a) internal kernel names: kernel_name, constant, inductive, module_path, DirPath.t

1b) other internal names: global_reference, abbreviation, extended_global_reference, global_dir_reference, ...

2) full, non ambiguous user names: full_path

3) non necessarily full, possibly ambiguous user names: reference and qualid

Most functions in this module fall into one of the following categories:

push : visibility -> full_user_name -> object_reference -> unit
Registers the object_reference to be referred to by the full_user_name (and its suffixes according to visibility). full_user_name can either be a full_path or a DirPath.t.
exists : full_user_name -> bool
Is the full_user_name already attributed as an absolute user name of some object?
locate : qualid -> object_reference
Finds the object referred to by qualid or raises Not_found
full_name : qualid -> full_user_name
Finds the full user name referred to by qualid or raises Not_found
shortest_qualid_of : object_reference -> user_name
The user_name can be for example the shortest non ambiguous qualid or the full_user_name or Id.t. Such a function can also have a local context argument.

Sourcetype object_prefix = {

obj_dir : Names.DirPath.t;
obj_mp : Names.ModPath.t;

}

Object prefix morally contains the "prefix" naming of an object to be stored by library, where obj_dir is the "absolute" path and obj_mp is the current "module" prefix.

Thus, for an object living inside Module A. Section B. the prefix would be:

{ obj_dir = "A.B"; obj_mp = "A"; }

Note that obj_dir is a "path" that is to say, as opposed to obj_mp which is a single module name.

Sourceval eq_op : object_prefix -> object_prefix -> bool

Sourcemodule GlobDirRef : sig ... end

to this type are mapped DirPath.t's in the nametab

Sourceexception GlobalizationError of Libnames.qualid

Sourceval error_global_not_found : info:Exninfo.info -> Libnames.qualid -> 'a

Raises a globalization error

Register visibility of things

The visibility can be registered either

for all suffixes not shorter then a given int -- when the object is loaded inside a module -- or
for a precise suffix, when the module containing (the module containing ...) the object is opened (imported)

Sourcetype visibility =

| Until of int
| Exactly of int

Sourceval map_visibility : (int -> int) -> visibility -> visibility

The following functions perform globalization of qualified names

These functions globalize a (partially) qualified name or fail with Not_found

Sourceval locate : Libnames.qualid -> Names.GlobRef.t

Sourceval locate_extended : Libnames.qualid -> Globnames.extended_global_reference

Sourceval locate_constant : Libnames.qualid -> Names.Constant.t

Sourceval locate_abbreviation : Libnames.qualid -> Globnames.abbreviation

Sourceval locate_modtype : Libnames.qualid -> Names.ModPath.t

Sourceval locate_dir : Libnames.qualid -> GlobDirRef.t

Sourceval locate_module : Libnames.qualid -> Names.ModPath.t

Sourceval locate_section : Libnames.qualid -> Names.DirPath.t

Sourceval locate_universe : Libnames.qualid -> Univ.UGlobal.t

Source

val locate_extended_nowarn : 
  Libnames.qualid ->
  Globnames.extended_global_reference

Remove the binding to an abbreviation

Sourceval remove_abbreviation : Libnames.full_path -> Globnames.abbreviation -> unit

These functions globalize user-level references into global references, like locate and co, but raise a nice error message in case of failure

Sourceval global : Libnames.qualid -> Names.GlobRef.t

Sourceval global_inductive : Libnames.qualid -> Names.inductive

These functions locate all global references with a given suffix; if qualid is valid as such, it comes first in the list

Sourceval locate_all : Libnames.qualid -> Names.GlobRef.t list

Source

val locate_extended_all : 
  Libnames.qualid ->
  Globnames.extended_global_reference list

Sourceval locate_extended_all_dir : Libnames.qualid -> GlobDirRef.t list

Sourceval locate_extended_all_modtype : Libnames.qualid -> Names.ModPath.t list

Sourceval locate_extended_all_module : Libnames.qualid -> Names.ModPath.t list

Source

val completion_canditates : 
  Libnames.qualid ->
  Globnames.extended_global_reference list

Experimental completion support, API is _unstable_

completion_canditates qualid will return the list of global references that have qualid as a prefix. UI usually will want to compose this with shortest_qualid_of_global

Mapping a full path to a global reference

Sourceval global_of_path : Libnames.full_path -> Names.GlobRef.t

Source

val extended_global_of_path : 
  Libnames.full_path ->
  Globnames.extended_global_reference

These functions tell if the given absolute name is already taken

Sourceval exists_cci : Libnames.full_path -> bool

Sourceval exists_modtype : Libnames.full_path -> bool

Sourceval exists_module : Names.DirPath.t -> bool

Sourceval exists_dir : Names.DirPath.t -> bool

Sourceval exists_universe : Libnames.full_path -> bool

These functions locate qualids into full user names

Sourceval full_name_modtype : Libnames.qualid -> Libnames.full_path

Sourceval full_name_module : Libnames.qualid -> Names.DirPath.t

Reverse lookup

Finding user names corresponding to the given internal name

Returns the full path bound to a global reference or syntactic definition, and the (full) dirpath associated to a module path

Sourceval path_of_abbreviation : Globnames.abbreviation -> Libnames.full_path

Sourceval path_of_global : Names.GlobRef.t -> Libnames.full_path

Sourceval dirpath_of_module : Names.ModPath.t -> Names.DirPath.t

Sourceval path_of_modtype : Names.ModPath.t -> Libnames.full_path

Sourceval path_of_universe : Univ.UGlobal.t -> Libnames.full_path

A universe_id might not be registered with a corresponding user name.

raises Not_found
if the universe was not introduced by the user.

Returns in particular the dirpath or the basename of the full path associated to global reference

Sourceval dirpath_of_global : Names.GlobRef.t -> Names.DirPath.t

Sourceval basename_of_global : Names.GlobRef.t -> Names.Id.t

Sourceval pr_global_env : Names.Id.Set.t -> Names.GlobRef.t -> Pp.t

Printing of global references using names as short as possible.

raises Not_found
when the reference is not in the global tables.

The shortest_qualid functions given an object with user_name Coq.A.B.x, try to find the shortest among x, B.x, A.B.x and Coq.A.B.x that denotes the same object.

raises Not_found
for unknown objects.
