(** * Load paths.
A load path is a physical path in the file system; to each load path is
associated a Coq [DirPath.t] (the "logical" path of the physical path).
*)
type t
(** Type of loadpath bindings. *)
val physical : t -> CUnix.physical_path
(** Get the physical path (filesystem location) of a loadpath. *)
val logical : t -> DirPath.t
(** Get the logical path (Coq module hierarchy) of a loadpath. *)
val get_load_paths : unit -> t list
(** Get the current loadpath association. *)
val get_paths : unit -> CUnix.physical_path list
(** Same as [get_load_paths] but only get the physical part. *)
val get_accessible_paths : unit -> CUnix.physical_path list
(** Same as [get_paths] but also get paths that can be relatively accessed. *)
val add_load_path : CUnix.physical_path -> bool -> DirPath.t -> unit
(** [add_load_path root phys log] adds the binding [phys := log] to the current
loadpaths. The [root] flag indicates whether this loadpath has to be treated
as a root one. *)
val remove_load_path : CUnix.physical_path -> unit
(** Remove the current logical path binding associated to a given physical path,
if any. *)
val find_load_path : CUnix.physical_path -> t
(** Get the binding associated to a physical path. Raises [Not_found] if there
is none. *)
val is_in_load_paths : CUnix.physical_path -> bool
(** Whether a physical path is currently bound. *)
val expand_path : DirPath.t -> (CUnix.physical_path * DirPath.t) list
(** Given a relative logical path, associate the list of absolute physical and
logical paths which are possible expansions of it. *)
val expand_root_path : DirPath.t -> CUnix.physical_path list
(** As [expand_path] but restricts to root loadpaths. *)
