27 ;; -- #### figure out how init.el and custom.el interact and put

|
|
|
31 ;;; This is a sample init.el file. It can be used without
|
|
|
32 ;;; modification as your init.el or .emacs. In older versions of
|
|
|
33 ;;; XEmacs, this file was called .emacs and placed in your home
|
|
|
34 ;;; directory. (Under MS Windows, that directory is controlled by the
|
|
|
35 ;;; HOME environment variable and defaults to C:\. You can find out
|
|
|
36 ;;; where XEmacs thinks your home directory is using
|
|
|
37 ;;;
|
|
|
38 ;;; ESC : (expand-file-name "~")
|
|
|
39 ;;;
|
|
|
40 ;;; . This means type ESC, then colon, then the following text, then hit
|
|
|
41 ;;; return.) In more recent versions of XEmacs, this file has migrated to
|
|
|
42 ;;; the .xemacs/ subdirectory and is called init.el. Other files are
|
|
|
43 ;;; also located here, such as custom.el (the auto-generated file
|
|
|
44 ;;; containing Customization options that you saved when using
|
|
|
45 ;;; Options->Save Options).
|
|
|
46
|
|

47 ;;; Changes to your init.el file will not take effect until the next

151 ;; newer versions of XEmacs but not older ones. The reason is that it

|

|
|
|
155 ;; the function with a different name -- typically, prefix it with the
|
|
|
156 ;; name of your module, which in this case might be `Init-'. For
|
|
|
157 ;; `emacs-version>=' we make an exception because (a) the function has
|
|
|
158 ;; been around a long time, (b) there isn't really any other
|
|
|
159 ;; functionality that is paired with it, (c) it's definition hasn't
|
|
|
160 ;; changed and isn't likely to, and (d) the calls to `emacs-version>='
|
|
|
161 ;; or its renamed replacement would be scattered throughout the code
|
|
|
162 ;; below, and with a replacement name the code would become
|
|
|
163 ;; significantly less portable into someone else's init.el file. (BUT
|
|
|
164 ;; NOTE BELOW: We do follow the procedure outlined above with renaming

165 ;; in a different case where the specifics are much different.)

170 ;; rearrange everything whenever I wanted to make any corrections to
