[48d74cb] | 5 | ;;; .emacs-singular - Emacs initialization file to use for |

| 6 | ;;; Singular interactive mode. |
---|
[f7ffaa] | 7 | ;;; |
---|
[48d74cb] | 8 | ;;; How you use this file very much depends on your attitude |
---|
| 9 | ;;; towards Emacs: |
---|
| 10 | ;;; |
---|
| 11 | ;;; 1) If you are going to use Emacs solely as frontend to |
---|
| 12 | ;;; Singular you do not have to worry at all about this file. |
---|
| 13 | ;;; 2) If you are already an experienced Emacs user you may |
---|
| 14 | ;;; want to copy this file's contents to your .emacs file. |
---|
| 15 | ;;; 3) If you are planning to become an experienced Emacs user |
---|
| 16 | ;;; you may use this file as starting point for your .emacs |
---|
| 17 | ;;; file, that is, for your Emacs initialization file. Simply |
---|
| 18 | ;;; copy it to your home directory and rename it to ".emacs" |
---|
| 19 | ;;; (without the quotes, of course). Then edit it as |
---|
| 20 | ;;; described below. |
---|
| 21 | ;;; |
---|
| 22 | ;;; In cases 2) and 3) you should be careful what exactly to copy |
---|
| 23 | ;;; to your .emacs file. In general, you need the following: |
---|
| 24 | ;;; |
---|
| 25 | ;;; o the hook-customizations with `add-hook'; |
---|
| 26 | ;;; o the pre-customized settings with `custom-set-variables' and |
---|
| 27 | ;;; `custom-set-faces'; |
---|
| 28 | ;;; o the code which creates menus for starting Singular; |
---|
| 29 | ;;; o the code which loads singular.el (located at the end of |
---|
| 30 | ;;; this file) you have to replace by something else, for |
---|
| 31 | ;;; example, an `autoload'. |
---|
| 32 | ;;; |
---|
| 33 | ;;; Here is how the Singular customization in your .emacs may |
---|
| 34 | ;;; look like: |
