How to interact with a running lisp instance? I have been trying to figure<br>
this out. I know this is being done with slime. Does any one have any good<br>
pointer on this. I am thinking of writing a web application and would like<br>
to be able to update it on the fly for updates and bug fixes.<br>

...an interesting idea.<br>
<br>
Years ago (1984), I had dinner with Nils Nilsson (AI pioneer) and he mentioned the idea that he wanted to build a system that once alive would never be powered down again - in his view a minor but necessary prerequisite of an AI system.<br>
<br>
It will be interesting to see what people will say about how to do this.<br>

I run a Lisp webapp from detachtty. It leaves a Unix socket around so you<br>
can talk to the fake tty later. I have done live-updates using this.<br>

<br>
Whether you pass functions as functions or symbols in various places can<br>
have an impact on your ability to do a live update (symbols being an<br>
indirect reference, are more conducive).<br>

Hi Steve,<br>
<br>
when I am running server-style lisp applications, I actually do start<br>
swank (the lisp side of slime) in it and at any time I wish, I can<br>
connect with slime to it and interact.<br>
<br>

The following blog post describes how to get Hunchentoot running on a Linux<br>
box with Swank running so that you can connect to the Lisp instance running<br>
the webserver through Slime:<br>

The best generic answer is probably the following:<br>
if you have started something at the REPL, you can interrupt the<br>
process (Ctrl-C or something like that)<br>
and bet a "break" prompt, from which you can do everything you can do<br>
from the regular prompt: load/compile files,<br>
define functions, fix bugs &c &c &c.<br>
Then you should be able to continue the process you just interrupted.<br>
<br>
A less generic answer would be to start an extra thread which would be<br>
listening on a port and then you can connect to that port to get a<br>
lisp prompt without interrupting all the other processes currently<br>
running.<br>
Then you can do everything (load/compile files, define functions, fix<br>
bugs &c &c &c) and the lisp should be able to figure out which<br>
processes have to be stopped for which actions (e.g., a process using<br>
CLOS might have to be stopped while low-level MOP stuff is redefined).<br>
You (and the lisp implementors) have to be careful, of course, about<br>
the safe points when things can be interrupted and watch out for the<br>
little things like if you interrupt lisp inside a recursive function F<br>
and redefine F, or if you redefine F by connecting to a separate<br>
thread, then you don't know whether the recursive calls to F will be<br>
using the new or the old definition of F unless you disassemble the<br>
old definition of F and find out whether the recursive call is<br>
compiled as a jump (old definition will be used) or as a (FUNCALL #'F)<br>
(also old definition) or as a (FUNCALL 'F) (new definition will be<br>
used).<br>
