Controlling fasl location

[Max Mikhanosha]

Here is what I been using for a few years, C-c C-k output goes to the
same place as asdf.  Note I don't remember why it does this through
find-symbol, but I it could be that Slime not always had the
*FASL-PATHNAME-FUNCTION* thing, and I wanted it to work on both new
and old slime.. You can probably convert find-symbol to defvar or
such.


;; Make C-c C-k in SLIME also use the correct directory
(let (fasl-finder-sym)
  (when (and (find-package :swank)
             (setq fasl-finder-sym
                   (find-symbol "*FASL-PATHNAME-FUNCTION*" :swank))
             (null (symbol-value fasl-finder-sym)))
    (set fasl-finder-sym
         (lambda (path options)
           (declare (ignore options))
           (let ((fasl-path
                   (asdf:apply-output-translations (compile-file-pathname path))))
             (when fasl-path
               (ensure-directories-exist fasl-path)
               fasl-path))))))
