I figured it might be potentially useful to describe what I'm hoping to do. I want to make a sequencing engine capable of sequencing deferred function calls, which is not hard to do when the interpreter is loaded as I can store lists in some structure that the clock part traverses. But I'd like it to be possible for a user at a repl to do something like insert an anonymous function on the timeline in order to make closures around other bits of state and have them captured for execution in a loop or whatever. So the tricky bit is how to store this such that one could close the session and reopen it, restoring those anon functions in their lists. So I guess this would mean being able to restore the environment and any function defs in that env. I think in common lisp this is called saving lisp images?
One possibility I thought of in case storing state like that just not practical would be to have some mechanism where the repl events could be replayed from a log, but I would think the ability to save the interpreter would be better. thanks iain On Wed, Aug 12, 2020 at 11:50 AM Iain Duncan <[email protected]> wrote: > Thanks Bill, I'd certainly be interested in hearing your thoughts on it. > > iain > > On Wed, Aug 12, 2020 at 11:48 AM <[email protected]> wrote: > >> There isn't a built-in way to save s7's state.
