Either way, this will generate mthesaur.elc, which ;; will be loaded instead of mthesaur.el. ;; ;; mthesaur.el was tested with GNU Emacs 21.3.1. ;; ;; ;; Using mthesaur ;; -------------- ;; ;; To lookup the word at the cursor, or to lookup the phrase in the ;; marked region, type: ;; ;; C-c t ;; ;; To be prompted to enter a word or phrase to be looked up, type: ;; ;; C-u C-c t ;; ;; The normal history manipulation commands (M-p, M-n, etc.) work as ;; expected at the minibuffer prompt. Even the words/phrases that were ;; added via `C-c t' will be in the history list. ;; ;; The 'C-c C-t' key sequence behaves identically to 'C-c t' except the ;; search results are appended to the end of the previous search results ;; instead of overwriting them. ;; ;; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; (eval-when-compile (require 'thingatpt) (require 'cl)) (defvar mthesaur-file (expand-file-name (substitute-in-file-name "D:/Pub/site-lisp/mthesaur.txt")) "*Location of the thesaurus file (mthesaur.txt).")
