The behavior of require when called with only one argument is
implementation-defined. In CMUCL, functions from the list
*module-provider-functions* are called in order with the
stringified module name as the argument. The first function to return
non-NIL is assumed to have loaded the module.
By default the functions module-provide-cmucl-defmodule and
module-provide- cmucl-library are on this list of functions, in
that order.
This is a list of functions taking a single argument.
require calls each function in turn with the stringified
module name. The first function to return non-NIL indicates
that the module has been loaded. The remaining functions, if any,
are not called.
To add new providers, push the new provider function onto the beginning of this list.
Defines a module by registering the files that need to be loaded when the module is required. If name is a symbol, its print name is used after downcasing it.
This function is the module-provider for modules registered by a
ext:defmodule form.
This function is the module-provider for CMUCL’s libraries, including Gray streams, simple streams, CLX, CLM, Hemlock, etc.
This function causes a file to be loaded whose name is formed by
merging the search-list “modules:” and the concatenation of
module-name with the suffix “-LIBRARY”. Note that both the
module-name and the suffix are each, separately, converted from
:case :common to :case :local. This merged name will be probed with
both a .lisp and .fasl extensions, calling LOAD if it exists.
