[slime-devel] *read-default-float-format* with C-c C-k, , load-system, etc.

[Dirk Gerrits]

Hi,

I'm not 100% sure this is a SLIME question, an ASDF question, or a
Common Lisp question, but I'll ask it here anyway.

In my program I'd like to have *read-default-float-format* be long-float
instead of the default single-float.  To accomplish this, I added 
  (eval-when (:compile-toplevel :load-toplevel :execute)
    (setq *read-default-float-format* 'long-float))
to package.lisp, which should be the first file to be compiled/loaded by
ASDF.  

Now if I do a ,load-system in the SLIME REPL, everything is fine:
*read-default-float-format* evaluates to long-float during compilation
and also does in the REPL.  However, if I open one of my files, and add
(defun foo () 50.0), do a C-M-x to compile it, and then call (foo) in
the REPL, I get 50.0f0 instead of 50.0d0.  C-c C-k doesn't help either,
and C-x C-e on the 50.0 also produces a single-float.  If I then save
the file and do another ,load-system, then (foo) in the REPL /will/
return 50.0d0, as expected.

How can I get C-M-x, C-c C-k and C-x C-e to use long-floats too?  Am I
doing something wrong that causes them to behave differently from
,load-system?  I'm using SLIME and Emacs from CVS, and have set
inferior-lisp-program and slime-multiprocessing to "sbcl" and t,
respectively.

Kind regards,
