Hello. I'm using latest CVS slime with emacs 22.0.50.1 (from the latest emacs-snapshot debian package). When ansi-color-for-commit-mode is on, M-x slime barfs (i'm attaching the backtrace). Invoking slime again, and reusing the inferior-lisp, things work ok. I can reliably reproduce this behaviour with emacs -nw -q (the same happens without -nw) and then (add-to-list 'load-path ...) (require 'slime) (slime-setup) (require 'ansi-color) (ansi-color-for-commit-mode-on) (slime) The error happens also if i use sbcl instead of cmucl. Unfortunately, i'm not privy enough with slime.el or ansi-color.el to grok from the backtrace what's going on, so any help will be appreciated. Thanks, jao -- We shall do a much better programming job, provided we approach the task with a full appreciation of its tremendous difficulty, provided that we respect the intrinsic limitations of the human mind and approach the task as very humble programmers.
