Saving runtime clojure image

[Jozef Wagner]

Hi,

I've read in some old discussion (
http://groups.google.com/group/clojure/browse_thread/thread/5259280f2fd8c8a5/
) that
"Clojure cannot save a runtime image the way SBCL and other Lisps
can."

Is this still true or is it possible to save-lisp-and-die? If not, are
there plans for such functionality or it is inherently impossible to
do such thing in clojure?

With such functionality, I could do some REPL hacking, save the
runtime state and later get back to it.

Best,
Jozef

Not provided by the underlying platform, the JVM.

But one could consider recording your interactions with the REPL, and having an option to replay them at startup.

With time, your REPL will start slower and slower and slower .... though.

And even with an "history replay" feature, there will be times when the replay is not sufficient (since you cannot totally control the I/O environment: date/time, file/network resources, etc.)

and serialized continuations ? could they be used to save a "image" of
a moment of a execution to return to it lately?
