keep slime alive

[Jens Teich]

I use SBCL and SLIME to set up a webserver with Edi Weitz'
Hunchentoot. How do I keep this process alive when closing
the emacs session?

Run your sbcl under slime and connect to it from emacs:

screen -S lisp sbcl

Then type:

(asdf:operate 'asdf:load-op :swank)
(swank:create-swank-server 4005)

You can now detatch your process by typing "C-a C-d". You can also
leave it open if you like.

Then start emacs and type M-x slime-connect to connect to the swank
process.

I'm sitting in front of a Windows Laptop connected to the Linux Server
via Putty.

First tried in the shell

| jens@h968740:~/lisp> screen -S lisp sbcl
| Cannot open your terminal '/dev/pts/2' - please check.

Then tried this within emacs with 

| M-x shell
| screen -S lisp sbcl
| (load "asdf.lisp")

two style warnings, ok

| (asdf:operate 'asdf:load-op) :swank)

...
debugger invoked on UNDEFINED FUNCTION in thread ... function
ASDF::MODULE-PROVIDE-ASDF

Thanks in advance for further hints.

ssh direct intoo your account (i.e. don't use su jens).

Seems the way you logged in when you started this emacs session was
sufficient to start screen, even though I never started screen from
within emacs.

Where do you have slime installed? There whould be a swank.asd in the
path specified by asdf:*central-registry*

I have established a symbolic link, so this should not be the problem.

Is it correct to execute the screen command within emacs-shell?

So can you start swank now?

I've never done it, but it should work if you can exit the eshell and
emacs and reconnect to it later. I usually run the screen command from
the shell. On my web-server I start screen from a crontab entry
(@reboot) and launch allegroserve when it starts up.

This problem is solved, I changed the user with su. After this I cannot
use screen. So starting the terminal with the correct user is the solution.

But the other problem remains.

I don't think so! In the first instance the *shell* buffer is not a  
good terminal emulation (M-x terminal RET can bring something  
better), secondly screen manages simple (hardware) terminals, that  
only exist once to give you many of them, and finally GNU Emacs  
allows you to have more than one *shell* or *terminal* buffer! GNU  
Emacs is the manager.

Yes (as I said initially don't su jens)

This is not related to screen.

It appears to be a problem with asdf, can you load other asd files or
is it just swank?

Yes I can load other asd files.

The difference between 'the other' packages and swank is that the other ones
are directly in my home directory and swank is in something like /usr/local/slime.
Could it be a problem that I have no writing permission there?

Problem solved.

Replaced (load "asdf.lisp") with (require :asdf) thanks to c.l.l.

Every step of the above ones works now fine. But I'm still unable to
logout and keep the process alive. Sorry if I should have mentioned
that earlier.

logout: there are stopped jobs

Are you sure you don't have any other processes running?


I'll show an example:

: itx ~; slogin roadrunner
Last login: Wed Jul 25 21:48:52 2007 from itx.home.gustad.com
: roadrunner ~; screen -S usenettest sbcl
(asdf:operate 'asdf:load-op :swank)

CL-USER> (defvar *usenet-test* 'hello)
*USENET-TEST*
CL-USER> 

M-x slime-disconnect
C-x C-c

: roadrunner ~; exit
logout
Connection to roadrunner closed.

: itx ~; slogin roadrunner
: roadrunner ~; screen -r usenettest
*USENET-TEST*

HELLO
(swank:create-swank-server 4005)

C-a C-d

emacs &
M-x slime-connect
