Loading

• current-load: parameter for a procedure that takes a filename to load and returns the value (or values; see Chapter 2) of the last expression read from the file. This load handler is called by load, load-relative, load/use-compiled, and load/cd. The default load handler reads expressions from the file (with compiled expressions enabled) and passes each expression to the current evaluation handler. The default load handler also treats a hash mark on the first line of the file as a comment (see section 14.3). The current load directory for loading the file is set before the load handler is called (see section 14.1).
• current-load-extension: parameter for a procedure that takes a filename to load as a dynamic extension (see section 14.7) and returns the extension's value(s). The default load extension handler loads an extension using operating system primitives.
• current-load-relative-directory: parameter for a complete directory pathname or #f. The current load-relative directory is set by load, load-relative, load/use-compiled, load/cd, load-extension, and load-relative-extension to the directory of the file being loaded. This parameter is used by load-relative, load/use-compiled and load-relative-extension (see section 14.1). When a new pathname is provided to the parameter procedure current-load-relative-directory, it is immediately expanded (see section 11.2.1) and the result must be a complete pathname for an existing directory.
