Module Load_path

module Load_path: sig .. end

Management of include directories.

This module offers a high level interface to locating files in the load path, which is constructed from -I command line flags and a few other parameters.

It makes the assumption that the contents of include directories doesn't change during the execution of the compiler.

val add_dir : string -> unit

Add a directory to the end of the load path (i.e. at lowest priority.)

val remove_dir : string -> unit

Remove a directory from the load path

val reset : unit -> unit

Remove all directories

module Dir: sig .. end

type auto_include_callback = (Dir.t -> string -> string option) -> string -> string

The type of callback functions on for init ~auto_include

val no_auto_include : auto_include_callback

No automatic directory inclusion: misses in the load path raise Not_found as normal.

val init : auto_include:auto_include_callback -> string list -> unit

init l is the same as reset (); List.iter add_dir (List.rev l)

val auto_include_otherlibs : (string -> unit) -> auto_include_callback

auto_include_otherlibs alert is a callback function to be passed to Load_path.init and automatically adds -I +lib to the load path after calling alert lib.

val get_paths : unit -> string list

Return the list of directories passed to add_dir so far.

val find : string -> string

Locate a file in the load path. Raise Not_found if the file cannot be found. This function is optimized for the case where the filename is a basename, i.e. doesn't contain a directory separator.

val find_uncap : string -> string

Same as find, but search also for uncapitalized name, i.e. if name is Foo.ml, allow /path/Foo.ml and /path/foo.ml to match.

val add : Dir.t -> unit

Deprecated.

Old name for Load_path.append_dir

val append_dir : Dir.t -> unit

append_dir d adds d to the end of the load path (i.e. at lowest priority.

val prepend_dir : Dir.t -> unit

prepend_dir d adds d to the start of the load path (i.e. at highest priority.

val get : unit -> Dir.t list

Same as get_paths (), except that it returns a Dir.t list.
