Nametab (p.rocq-runtime.9.1.0.doc.rocq-runtime.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.

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

Specializations for extended references

These functions operate on XRefs but are about a subset of extended_global_reference for convenience.

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.

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

These functions globalize user-level references into global references, like locate and co, but raise GlobalizationError for unbound qualid and UserError for type mismatches (eg global_inductive when the qualid is bound to a constructor)

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

Sourceval global_inductive : Libnames.qualid -> Names.inductive

These functions declare (resp. return) the source location of the object if known

Sourceval set_cci_src_loc : Globnames.extended_global_reference -> Loc.t -> unit

Sourceval cci_src_loc : Globnames.extended_global_reference -> Loc.t option

Nametab generators
