[Reported to the author 060520] Currently the function slime-repl-merge-histories appears to be buggy in not deleting duplicates, and maintaining order. For example: ELISP> (slime-repl-merge-histories '(1 2 3 4 5) '(2 3 4 8)) (8 1 5 2 3 4) ELISP> (slime-repl-merge-histories '(1 2 3 4 5 1 2 3 4 5) '(2 3 4 8)) (8 1 5 1 5 2 3 4) I believe the desired result is: (2 3 4 8 1 5) so M-p in a fresh repl will pick the last (latest) item from the previous repl session. I believe the following Changelog entry applies, |2005-10-11 Stefan Kamphausen <skampi@gmx.net> and would suggest a simpler function that uses delete-duplicates (for strings): (defun slime-repl-merge-histories (old-hist new-hist) "Merge entries from OLD-HIST and NEW-HIST." (remove-duplicates (append new-hist old-hist) :test 'string= :from-end t)) -- Madhu -- ======================================================================= Open system or closed system, enlightenment or ideology, those are the questions.
