Kernel#autoload

(::interned _module, ::String filename) -> ::NilClass

autoload(const, filename) → nil

static VALUE
rb_f_autoload(VALUE obj, VALUE sym, VALUE file)
{
    VALUE klass = rb_class_real(rb_vm_cbase());
    if (!klass) {
        rb_raise(rb_eTypeError, "Can not set autoload on singleton class");
    }
    return rb_mod_autoload(klass, sym, file);
}

Registers filename to be loaded (using Kernel::require) the first time that const (which may be a String or a symbol) is accessed.

Example

autoload(:MyModule, "/usr/local/lib/modules/my_module.rb")

If const is defined as autoload, the file name to be loaded is replaced with filename. If const is defined but not as autoload, does nothing.
