slime + clisp + emacs: server disconnects
by Stuart Little 25 Jul '19

25 Jul '19

I am running - emacs 26.2 - slime 2.24 - clisp 2.49 on Linux. Running M-x slime in emacs with 'inferior-lisp-program' set to 'clisp' starts slime fine. I can usually run one evaluation (like say (+ 2 3)), whereupon any other action (pressing 'enter', say) will result in a disconnect: Lisp connection closed unexpectedly: connection broken by remote peer The inferior-lisp buffer reads as follows after the disconnect: --- buffer starts --- (progn (load "/home/chirvasitua/quicklisp/dists/quicklisp/software/slime-v2.24/swank-loader.lisp" :verbose t) (funcall (read-from-string "swank-loader:init") :from-emacs t) (funcall (read-from-string "swank:start-server") "/tmp/slime.19223")) i i i i i i i ooooo o ooooooo ooooo ooooo I I I I I I I 8 8 8 8 8 o 8 8 I \ `+' / I 8 8 8 8 8 8 \ `-+-' / 8 8 8 ooooo 8oooo `-__|__-' 8 8 8 8 8 | 8 o 8 8 o 8 8 ------+------ ooooo 8oooooo ooo8ooo ooooo 8 Welcome to GNU CLISP 2.49 (2010-07-07) <http://clisp.cons.org/> Copyright (c) Bruno Haible, Michael Stoll 1992, 1993 Copyright (c) Bruno Haible, Marcus Daniels 1994-1997 Copyright (c) Bruno Haible, Pierpaolo Bernardi, Sam Steingold 1998 Copyright (c) Bruno Haible, Sam Steingold 1999-2000 Copyright (c) Sam Steingold, Bruno Haible 2001-2010 Type :h and hit Enter for context help.

I have sbcl too (switched to it after the clisp shenanigans started upon upgrading to v2.24): It does *not* crash, and I'm perfectly happy using sbcl. I was just impelled by curiosity to try and figure out what's wrong on the clisp side.

slime meta-dot in ASDF sources [cross-post from ASDF-devel]
by Mark H. David 19 Jul '19

[The main ASDF dev Robert Goldman answered this partly in ASDF-devel mailing list, but in doing so led me to believe the SLIME devs would know more, hence the crosspost. -MHD] How do ASDF developers using emacs with SLIME deal with doing meta-dot (meta-.) on function names in ASDF sources. Out of the box, mostly when I meta-. just goes to one big top-level form that starts like this (with-upgradability () (define-condition invalid-source-registry (invalid-configuration warning) Thanks for clues, -Mark
