- (current-load [proc]) gets or sets 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 [proc]) gets or sets 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 [path]) gets or sets 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 converted to an immutable string;
the result must be a complete pathname for an existing directory.
- (use-compiled-file-kinds [kind-symbol]) gets or sets a symbol, either
'all, 'non-elaboration, or
'none, indicating whether load/used-compiled
(and thus require-library) recognizes compiled files. If
the value of this parameter is 'all, then
load/use-compiled recognizes compiled files as described in
section 14.1. If the value is 'none, then
load/use-compiled ignores compiled files. If the value is
'non-elaboration, then load/use-compiled recognizes
compiled files except for .zo files that start with 'e
followed by a space, which is a special annotation installed by
compile-file (see section 15.2.5) to indicate that a file
contains elaboration-time expressions.
