Controlling fasl location

[Paul Bowyer]

Hello Helmut,

I found this link on the slime-developer mailing list and I wondered if 
it is usable and if so, how would I implement it? I don't have a lot of 
experience fiddling with slime's internals.
http://article.gmane.org/gmane.lisp.slime.devel/8378/match=fasl

Is there some other convenient way to set the location for fasl files 
from within a slime session so that when I do a compile/load, the fasl 
goes to the same location as the output from asdf. Currently the output 
from asdf goes to one place, and the output from compile/load goes to my 
source directory.

I'm looking for a simple function call that would pass a pathname or 
would return to the default if no pathname was passed or maybe just a 
variable that I can set from within a slime session that would do the 
job. I only want this to to happen for some projects and not happen for 
others that don't yet use asdf.

Thanks,

Paul Bowyer
