# 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`.
