-3.0: Customization - Emacs Lisp and .emacs
-==========================================
-
-Q3.0.1: What version of Emacs am I running?
--------------------------------------------
-
- How can `.emacs' determine which of the family of Emacsen I am using?
-
- To determine if you are currently running GNU Emacs 18, GNU Emacs 19,
-XEmacs 19, XEmacs 20, or Epoch, and use appropriate code, check out the
-example given in `etc/sample.emacs'. There are other nifty things in
-there as well!
-
- For all new code, all you really need to do is:
-
- (defvar running-xemacs (string-match "XEmacs\\|Lucid" emacs-version))
-

-
-Q3.0.2: How can I evaluate Emacs-Lisp expressions?
---------------------------------------------------
-
- I know I can evaluate Elisp expressions from `*scratch*' buffer with
-`C-j' after the expression. How do I do it from another buffer?
-
- Press `M-:' (the default binding of `eval-expression'), and enter
-the expression to the minibuffer. In XEmacs prior to 19.15
-`eval-expression' used to be a disabled command by default. If this is
-the case, upgrade your XEmacs.
-

-
-Q3.0.3: `(setq tab-width 6)' behaves oddly.
--------------------------------------------
-
- If you put `(setq tab-width 6)' in your `.emacs' file it does not
-work! Is there a reason for this? If you do it at the EVAL prompt it
-works fine!! How strange.
-
- Use `setq-default' instead, since `tab-width' is all-buffer-local.

-
-Q3.0.4: How can I add directories to the `load-path'?
------------------------------------------------------
-
- Here are two ways to do that, one that puts your directories at the
-front of the load-path, the other at the end:
-
- ;;; Add things at the beginning of the load-path, do not add
- ;;; duplicate directories:
- (pushnew "bar" load-path :test 'equal)
-
- (pushnew "foo" load-path :test 'equal)
-
- ;;; Add things at the end, unconditionally
- (setq load-path (nconc load-path '("foo" "bar")))

- To add directories using Unix shell metacharacters use

-
-Q3.0.5: How to check if a lisp function is defined?
----------------------------------------------------
-
- Use the following elisp:
-
- (fboundp 'foo)
-
- It's almost always a mistake to test `emacs-version' or any similar
-variables.
-
- Instead, use feature-tests, such as `featurep', `boundp', `fboundp',
-or even simple behavioral tests, eg.:
-
- (defvar foo-old-losing-code-p
- (condition-case nil (progn (losing-code t) nil)
- (wrong-number-of-arguments t)))
-
- There is an incredible amount of broken code out there which could
-work much better more often in more places if it did the above instead
-of trying to divine its environment from the value of one variable.

-
-Q3.0.6: Can I force the output of `(face-list)' to a buffer?
-------------------------------------------------------------
-
- It would be good having it in a buffer, as the output of
-`(face-list)' is too wide to fit to a minibuffer.
-
- Evaluate the expression in the `*scratch*' buffer with point after
-the rightmost paren and typing `C-j'.
-
- If the minibuffer smallness is the only problem you encounter, you
-can simply press `C-h l' to get the former minibuffer contents in a
-buffer.

-
- For XEmacs 19.14 and previous:
-
- John Mann <mannj@ll.mit.edu> writes:
-
- You have to go to Options->Frame Appearance and unselect
- `Frame-Local Font Menu'. If this option is selected, font changes
- are only applied to the *current* frame and do *not* get saved
- when you save options.
-
- For XEmacs 19.15 and later:
-
- Implement the above as well as set the following in your `.emacs'
-
- (setq options-save-faces t)

-
-Q3.0.9: What is `Customize'?
-----------------------------
-
- Starting with XEmacs 20.2 there is new system 'Customize' for
-customizing XEmacs options.
-
- You can access `Customize' from the `Options' menu or invoking one
-of customize commands by typing eg. `M-x customize', `M-x
-customize-face', `M-x customize-variable' or `M-x customize-apropos'.
-
- Starting with XEmacs 20.3 there is also new `browser' mode for
-Customize. Try it out with `M-x customize-browse'

-3.1: X Window System & Resources
-================================
-
-Q3.1.1: Where is a list of X resources?
----------------------------------------
-
- Search through the `NEWS' file for `X Resources'. A fairly
-comprehensive list is given after it.
-
- In addition, an `app-defaults' file is supplied, `etc/Emacs.ad'
-listing the defaults. The file `etc/sample.Xdefaults' gives a set of
-defaults that you might consider. It is essentially the same as
-`etc/Emacs.ad' but some entries are slightly altered. Be careful about
-installing the contents of this file into your `.Xdefaults' or
-`.Xresources' file if you use GNU Emacs under X11 as well.

- You can test the return value of the function `(device-class)', as
-in:
-
- (when (eq (device-class) 'color)
- (set-face-foreground 'font-lock-comment-face "Grey")
- (set-face-foreground 'font-lock-string-face "Red")

---------------------------------------------------------------
-
- In Lucid Emacs 19.6 I did `(set-screen-width CHARACTERS)' and
-`(set-screen-height LINES)' in my `.emacs' instead of specifying
-`Emacs*EmacsScreen.geometry' in my `.Xdefaults' but this does not work
-in XEmacs 19.13.

- In XEmacs 19.11 I specified `Emacs*EmacsScreen.geometry' in my
-`.emacs' but this does not work in XEmacs 19.15.

-
- Add the following line to your `.emacs':
-
- (setq frame-title-format "%S: %f")

- A more sophisticated title might be:
-
- (setq frame-title-format

OLWM grabs the `help' key, and retransmits it to the appropriate

Generally, the simplest way is to define a key as Multi_key with
xmodmap, e.g.
- xmodmap -e 'keycode 0xff20 = Multi_key'
+ xmodmap -e 'keycode 0xff20 = Multi_key'
You will need to pick an appropriate keycode. Use xev to find out
the keycodes for each key.

Once you have Multi_key defined, you can use e.g.
- Multi a ' => á
- Multi e " => ë
- Multi c , => ç
+ Multi a ' => á
+ Multi e " => ë
+ Multi c , => ç
etc.
Also, recent versions of XFree86 define various AltGr-<key>
combinations as dead keys, i.e.
- AltGr [ => dead_diaeresis
- AltGr ] => dead_tilde
- AltGr ; => dead_acute
+ AltGr [ => dead_diaeresis
+ AltGr ] => dead_tilde
+ AltGr ; => dead_acute
etc.
Running `xmodmap -pk' will list all of the defined keysyms.

modifier keys like Control and Meta as well.

+3.10: Text Selections
+=====================
+
+Q3.10.1: How can I turn off or change highlighted selections?
+-------------------------------------------------------------
+
+ The `zmacs' mode allows for what some might call gratuitous
+highlighting for selected regions (either by setting mark or by using
+the mouse). This is the default behavior. To turn off, add the
+following line to your `.emacs' file:
+
+ (setq zmacs-regions nil)
+
+ Starting with XEmacs-20.2 you can also change this with Customize.
+Select from the `Options' menu `Customize->Emacs->Editing->Basics->Zmacs
+Regions' or type `M-x customize <RET> editing-basics <RET>'.
+
+ To change the face for selection, look at `Options->Customize' on
+the menubar.

+
+Q3.10.2: How do I get that typing on an active region removes it?
+-----------------------------------------------------------------
+
+ I want to change things so that if I select some text and start
+typing, the typed text replaces the selected text, similar to Motif.
+
+ You want to use something called "pending delete". Pending delete
+is what happens when you select a region (with the mouse or keyboard)
+and you press a key to replace the selected region by the key you typed.
+Usually backspace kills the selected region.
+
+ To get this behavior, add the following lines to your `.emacs':
+
+ (cond
+ ((fboundp 'turn-on-pending-delete)
+ (turn-on-pending-delete))
+ ((fboundp 'pending-delete-on)
+ (pending-delete-on t)))
+
+ Note that this will work with both Backspace and Delete. This code
+is a tad more complicated than it has to be for XEmacs in order to make
+it more portable.

+-----------------------------------------------------

+not able to see what's underneath. How do I turn it off?
+
+ Put the following in your `.emacs':
+
+ (setq isearch-highlight nil)
+
+ Starting with XEmacs-20.2 you can also change this with Customize.
+Type `M-x customize-variable <RET> isearch-highlight <RET>'.
+
+ Note also that isearch-highlight affects query-replace and ispell.
+Instead of disabling isearch-highlight you may find that a better
+solution consists of customizing the `isearch' face.

+ This has been fixed by default starting with XEmacs-20.3.
+
+ With older versions you can turn this feature (if it indeed is a
+feature) off like this:
+
+ (defadvice scroll-up (around scroll-up freeze)
+ (interactive "_P")
+ (let ((zmacs-region-stays t))
+ (if (interactive-p)
+ (condition-case nil
+ ad-do-it
+ (end-of-buffer (goto-char (point-max))))
+ ad-do-it)))
+
+ (defadvice scroll-down (around scroll-down freeze)
+ (interactive "_P")
+ (let ((zmacs-region-stays t))
+ (if (interactive-p)
+ (condition-case nil
+ ad-do-it
+ (beginning-of-buffer (goto-char (point-min))))
+ ad-do-it)))

+4.0: Reading Mail with VM
+=========================
+
+Q4.0.1: How do I set up VM to retrieve mail from a remote site using POP?
+-------------------------------------------------------------------------
+
+ Use `vm-spool-files', like this for example:
+
+ (setq vm-spool-files '("/var/spool/mail/wing"
+ "netcom23.netcom.com:110:pass:wing:MYPASS"))
+
+ Of course substitute your actual password for MYPASS.

+
+Q4.0.2: How do I get VM to filter mail for me?
+----------------------------------------------
+
+ One possibility is to use procmail to split your mail before it gets
+to VM. I prefer this personally, since there are many strange and
+wonderful things one can do with procmail. Procmail may be found at
+`ftp://ftp.informatik.rwth-aachen.de/pub/packages/procmail/'.
+
+ Also see the Mail Filtering FAQ at:
+`ftp://rtfm.mit.edu/pub/usenet/news.answers/mail/filtering-faq'.

+------------------------------------
+
+ My mailbox lives at the office on a big honkin server. My regular

+mail at home without storing it here and I'd like to use xemacs and VM
+at home... Is there a recommended setup?

+
+ There are several ways to do this.
+
+ 1. Set your display to your home machine and run dxpc or one of
+ the other X compressors.
+
+ 2. NFS mount your desktop machine on your home machine and
+ modify your pop command on your home machine to rsh to your
+ desktop machine and actually do the pop get's.
+
+ 3. Run a POP server on your desktop machine as well and do a
+ sort of two tiered POP get.
+
+ William Perry <wmperry@monolith.spry.com> adds:
+
+ Or you could run a pop script periodically on your desktop
+ machine, and just use ange-ftp or NFS to get to your mailbox. I
+ used to do this all the time back at IU.

+
+Q4.0.9: rmail or VM gets an error incorporating new mail.
+---------------------------------------------------------
+
+ Quoting the XEmacs PROBLEMS file:
+
+ rmail and VM get new mail from `/usr/spool/mail/$USER' using a
+ program called `movemail'. This program interlocks with
+ `/bin/mail' using the protocol defined by `/bin/mail'.
+
+ There are two different protocols in general use. One of them
+ uses the `flock' system call. The other involves creating a lock
+ file; `movemail' must be able to write in `/usr/spool/mail' in
+ order to do this. You control which one is used by defining, or
+ not defining, the macro `MAIL_USE_FLOCK' in `config.h' or the m-
+ or s- file it includes.
+
+ *IF YOU DON'T USE THE FORM OF INTERLOCKING THAT IS NORMAL ON YOUR
+ SYSTEM, YOU CAN LOSE MAIL!*
+
+ If your system uses the lock file protocol, and fascist
+ restrictions prevent ordinary users from writing the lock files in
+ `/usr/spool/mail', you may need to make `movemail' setgid to a
+ suitable group such as `mail'. You can use these commands (as
+ root):
+
+ chgrp mail movemail
+ chmod 2755 movemail
+
+ If your system uses the lock file protocol, and fascist
+ restrictions prevent ordinary users from writing the lock files in
+ `/usr/spool/mail', you may need to make `movemail' setgid to a
+ suitable group such as `mail'. To do this, use the following
+ commands (as root) after doing the make install.
+
+ chgrp mail movemail
+ chmod 2755 movemail
+
+ Installation normally copies movemail from the build directory to
+ an installation directory which is usually under `/usr/local/lib'.
+ The installed copy of `movemail' is usually in the directory
+ `/usr/local/lib/emacs/VERSION/TARGET'. You must change the group
+ and mode of the installed copy; changing the group and mode of the
+ build directory copy is ineffective.
