— Scheme Procedure: load filename

Load filename and evaluate its contents in the top-level environment. The load paths are not searched. If the variable %load-hook is defined, it should be bound to a procedure that will be called before any code is loaded. See documentation for %load-hook later in this section.

— Scheme Procedure: load-from-path name

Load a Scheme source file named NAME, searching for it in the directories listed in %load-path, and applying each of the file name extensions listed in %load-extensions.

— Scheme Procedure: primitive-load filename
— C Function: scm_primitive_load (filename)

Load filename and evaluate its contents in the top-level environment. The load paths are not searched; filename must either be a full pathname or a pathname relative to the current directory. If the variable %load-hook is defined, it should be bound to a procedure that will be called before any code is loaded. See documentation for %load-hook later in this section.

— Scheme Procedure: primitive-load-path filename
— C Function: scm_primitive_load_path (filename)

Search %load-path for filename and load it into the top-level environment. If filename does not name a loadable file, signal error.

— Scheme Procedure: %search-load-path filename
— C Function: scm_sys_search_load_path (filename)

Search %load-path for filename, which must be readable by the current user. If filename is found in the list of paths to search or is an absolute pathname, return its full pathname. Otherwise, return #f. Filenames may have any of the optional extensions in the %load-extensions list; %search-load-path will try each extension automatically.

— Variable: %load-hook

A procedure to be run whenever primitive-load is called. If this procedure is defined, it will be called with the filename argument that was passed to primitive-load.

          (define %load-hook (lambda (file)
                               (display "Loading ")
                               (display file)
                               (write-line "....")))
          
          (load-from-path "foo.scm")
          -| Loading /usr/local/share/guile/site/foo.scm....

— Scheme Procedure: current-load-port
— C Function: scm_current_load_port ()

Return the current-load-port. The load port is used internally by primitive-load.

— Variable: %load-extensions

A list of default file extensions for files containing Scheme code. %search-load-path tries each of these extensions when looking for a file to load. By default, %load-extensions is bound to the list ("" ".scm").
