For instance, activating ;; the show-paren-mode for Mathematica buffers can be done as follows: ;; (setq mathematica-m-mode-hook (function (lambda () (interactive) ;; (setq mathematica-m-mode-hook-done 1) ;; (show-paren-mode) ;; ))) ;;;; Notes to the Maintainer: ;; bugs/todo: ;; change history: ;; June 21, 2004: fix for (goto-char eline); I moved it after the pop-to-buffer command. ;; June 17, 2004: ;; fix to get the rigth window-width for the Mathematica process buffer. ;; ;; June 16, 2004: ;; 3. respects the window layout of the user: ;; uses pop-to-buffer, and no longer switch-to-buffer. ;; we set pop-up-windows, a configuration variable for pop-to-buffer, to nil. ;; 2. dabbrev friend buffers configured ;; 1. indentation modified ;; 0. ;; changed to dabbrev-expand, ;; since dabbrev-completion bugs the user with a list of possible completions in a new window. ;; May 24, 2004: write a mode help text (appears with C-h m). ;; May 24, 2004: dabbrev support in the *mathematica* shell buffer, too. ;; Feb 1, 2003: add indentation support. ;; Jan 30, 2003: ;; support Mathematica's nested comments. ;; comment delims in strings, ie " (* ", don't count. ;; Jan 28, 2003: removed debug support. ;; removed indentation support. ;; Jan 27, 2003: Started from mma.el,v 1.32 2000/06/27 16:05:19 ;; Author: Tim Wichmann ;;;; Code: (defconst mathematica-m-version "June 2004" "The version of mathematica.el.
