This is so one doesn't have to wonder if the ;; target is north or south in the buffer. ;; ;; The philosophy is that `wrap-search' mostly shouldn't be ;; used for searching - that is possible as well, of course, ;; using the same command - rather, it is used to quickly ;; navigate a buffer. ;; ;; To use the package without keyboard shortcuts isn't ;; recommended. Instead, do for example ;; ;; (global-set-key "\C-s" #'wrap-search) ;; (global-set-key "\C-r" #'wrap-search-again) ;; ;;; Code: (let ((prev-str "unspecified search string") (prev-case) (prev-rev) (prev-beg) (prev-end) ) (defun wrap-search-again () (interactive) (wrap-search prev-str prev-case prev-rev prev-beg prev-end) ) (declare-function wrap-search-again nil) (defun wrap-search-show-default () (truncate-string-to-width prev-str 10 nil nil t) ) (declare-function wrap-search-show-default nil) (defun wrap-search (str &optional case rev beg end) "Search for STR.
