i decided to make a sample.emacs that's really useful -- lots of stuff that users really want and no stuff that's really annoying or useless, at least not by default. i also added lots of explanatory comments, which should really help beginning Lisp coders out. i'm attaching the result so far. i'm interested in seeing other people's init.el files so i can mine other interesting stuff. please feel free to mail me. i'm especially interested in code that enables various packages. [eventually i hope to make an `enable-behavior' function so you can turn on and off these features just by giving a name, without having to utter lots of obscure incantations.] -- ben I'm sometimes slow in getting around to reading my mail, so if you want to reach me faster, call 520-661-6661.

(Under MS Windows, that directory is controlled by the ;;; HOME environment variable and defaults to C:\.

In more recent versions of XEmacs, this file has migrated to ;;; the .xemacs/ subdirectory and is called init.el. Other files are ;;; also located here, such as custom.el (the auto-generated file ;;; containing Customization options that you saved when using ;;; Options->Save Options). ;;; Changes to your init.el file will not take effect until the next ;;; time you start up XEmacs, unless you load it explicitly with ;;; ;;; M-x load-file RET ~/.xemacs/init.el RET ;;; ;;; There is a great deal of documentation on customization in the ;;; XEmacs User's Manual. You can read this manual with the online ;;; Info browser: Select Help->Info (Online Docs)->XEmacs User's ;;; Manual (if there is such an entry), or ->Info Contents (or type ;;; `C-h i') and then *middle-click* the XEmacs entry.  ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;; Basic Customization ;; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ;; TIP: Control-L characters are ignored in Lisp files and are the ;; standard way of indicating major section divisions. You can enter ;; such a character using C-q C-l. ;; Define a variable to indicate whether we're running XEmacs/Lucid ;; Emacs. (You do not have to defvar a global variable before using ;; it -- you can just call `setq' directly. It's clearer this way, ;; though. Note also how we check if this variable already exists ;; using `boundp', because it's defined in recent versions of ;; XEmacs.) (or (boundp 'running-xemacs) (defvar running-xemacs (string-match "XEmacs\\|Lucid" emacs-version))) ;; Define a function to make it easier to check which version we're ;; running.

(It's good ;; style to do this, in case some improvement was made to the ;; already-existing function -- otherwise we might subsitute an older ;; definition and possibly break some code elsewhere.) ;; ;; TIP: At this point you may be wondering how I wrote all these nice, ;; long, nicely-justified textual stretches -- didn't I go crazy ;; sticking in the semicolons everywhere and having to delete them and ;; rearrange everything whenever I wanted to make any corrections to ;; the text? The answer is -- of course not! Use M-q. This does all ;; the magic for you, justifying and breaking lines appropriately and ;; putting any necessary semicolons or whatever at the left (it ;; figures out what this ought to be by looking in a very clever ;; fashion at what's already at the beginning of each line in the ;; paragraph). You may need `filladapt' set up (it's done below in ;; this file) in order for this to work properly.
