从 CCL 检索(加载)ed 源代码?

Retrieving (load)ed source code from CCL?

我用 CCL 调用了 (load "code.lisp"),然后不小心删除了 code.lisp。有什么办法可以找回源码吗? CCL 是否在任何地方的内存中?

这是一个非常特殊的功能。这里只针对 Clozure CL。该代码在其他任何地方都不起作用。这在 CCL IDE 中对我有用。它检索某个包中 :internal:external 符号的源代码。对于从其他包继承的符号,它不会这样做(你通常会从包 CLCCL 中获得源代码,这有点太多了)。

(defun retrieve-source-code (&optional (package *package*))
  (do-symbols (s package)
    (multiple-value-bind (symbol where)
                         (find-symbol (symbol-name s)
                                      package)
      (declare (ignore symbol))
      (when (member where '(:internal :external))
        (let ((ds (find-definition-sources s)))
          (when (and ds (listp ds))
            (loop for (nil sn) in ds
              for snt = (source-note-text sn)
              when snt do (progn
                            (terpri)
                            (princ snt)
                            (terpri)))))))))

如您所见,它可以自行检索(以及更多):

? (retrieve-source-code)

(defun retrieve-source-code (&optional (package *package*))
    (do-symbols (s package)
      (multiple-value-bind (symbol where)
                           (find-symbol (symbol-name s)
                                        package)
        (declare (ignore symbol))
        (when (member where '(:internal :external))
          (let ((ds (find-definition-sources s)))
            (when (and ds (listp ds))
              (loop for (nil sn) in ds
                for snt = (source-note-text sn)
                when snt do (progn
                              (terpri)
                              (princ snt)
                              (terpri)))))))))
NIL
