* 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 logical : t -> Names.DirPath.t

Get the logical path (Coq module hierarchy) of a loadpath.

val physical : t -> CUnix.physical_path

Get the physical path of a loadpath

val pp : t -> Pp.t

Print a load path

val get_load_paths : unit -> t list

Get the current loadpath association.

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 with a physical path. Raises Not_found if there is none.

val find_with_logical_path : Names.DirPath.t -> t list

get the list of load paths that correspond to a given logical path

val locate_file : string -> string

Locate a file among the registered paths. Do not use this function, as it does not respect the visibility of paths.

type library_location =
  1. | LibLoaded
  2. | LibInPath

Locate a library in the load path

type locate_error =
  1. | LibUnmappedDir
  2. | LibNotFound
type 'a locate_result = ('a, locate_error) result

Locates a library by implicit name.

  • raises LibNotFound

    if there is no corresponding file in the path

val try_locate_absolute_library : Names.DirPath.t -> string
Extending the Load Path
type vo_path = {
  1. unix_path : string;
    (*

    Filesystem path containing vo/ml files

    *)
  2. coq_path : Names.DirPath.t;
    (*

    Coq prefix for the path

    *)
  3. implicit : bool;
    (*

    implicit = true avoids having to qualify with coq_path

    *)
  4. has_ml : bool;
    (*

    If has_ml is true, the directory will also be added to the ml include path

    *)
  5. recursive : bool;
    (*

    recursive will determine whether we explore sub-directories

    *)
}

Adds a path to the Coq and ML paths

val add_vo_path : vo_path -> unit
