[slime-devel] setting heap size for SBCL for use with SLIME
Hi, I'm wondering if anyone knows how to configure SLIME to increase SBCL's heap size. I found the question http://stackoverflow.com/questions/7181183/how-to-configure-sbcl-to-use-more... but the listed answer doesn't work for me, namely, putting (setq inferior-lisp-program "sbcl --dynamic-space-size 1024") in ~/.emacs. The default value is 512Mb. I'm using the following function to determine the heap size. This code was posted by Nikodemus Siivola on SBCL help, see http://comments.gmane.org/gmane.lisp.steel-bank.general/1914 (define-alien-variable ("dynamic_space_size" dynamic-space-size-bytes) unsigned-long) (defun heap-n-bytes () (+ dynamic-space-size-bytes (- sb-vm::read-only-space-end sb-vm::read-only-space-start) (- sb-vm::static-space-end sb-vm::static-space-start))) Please CC me on any reply. Thanks. Regards, Faheem

As long as you're not using slime-lisp-implementations in your ~/.emacs, setting inferior-lisp-program should work. If you're using slime-lisp-implementations, you have to modify this variable because slime ignores inferior-lisp-program if slime-lisp-implementations is not nil: (setq slime-lisp-implementations '((sbcl ("sbcl" "--dynamic-space-size" "1024")))) -- Dirk

Hi Dirk, Thanks for the reply. I'm not aware of setting slime-lisp-implementations anywhere. I do have some third-party slime code in my .emacs, but it doesn't mention slime-lisp-implementations. How can I check whether I am using slime-lisp-implementations? Regards, Faheem

Just evaluate the variable slime-lisp-implementations, e.g. with M-x eval-expression. If it's nil or not bound then it will not be used. Helmut

Hmm. it returns (("sbcl" ("sbcl")) ("clisp" ("clisp")) ("ecl" ("ecl")) ("cmucl" ("cmucl"))) What does this mean? Regards, Faheem

The variable is documented here http://common-lisp.net/project/slime/doc/html/Multiple-Lisps.htm. or just use M-x describe-variable. If you just want to set the heap size put this in your .emacs: (setq slime-lisp-implementations '((sbcl ("sbcl" "--dynamic-space-size" "1024")))) If you want to figure out who or what sets it's to the value it has, also check /etc/emacs/site-lisp/ or /usr/share/emacs/site-lisp/ Helmut

Hi Helmut, Thanks very much for your helpful answers. I tried this out and it worked, though I used (setq slime-lisp-implementations '(("sbcl" ("sbcl" "--dynamic-space-size" "1024")) ("clisp" ("clisp")) ("ecl" ("ecl")) ("cmucl" ("cmucl")))) instead. I also added an answer to http://stackoverflow.com/questions/7181183/how-to-configure-sbcl-to-use-more... I quoted from you and Dirk Sondermann. I hope that's Ok. Regards, Faheem

A tangent, but: as of late last year you can just use SB-EXT:DYNAMIC-SPACE-SIZE. Cheers, -- nikodemus
