TextFile

The interface between GNU Emacs and Sun windows consists of the program
etc/emacstool, the Lisp programs lisp/sun-*.el and lisp/term/sun.el,
and the C source file src/sunfns.c.  It is documented with a man page,
etc/emacstool.1.

To enable use of these files and programs, define the configuration
switch HAVE_SUN_WINDOWS in src/config.h before compiling Emacs.
The definition of HAVE_SUN_WINDOWS must precede the #include m-sun2.h
or #include m-sun3.h.

This software is based on SunView for Sun UNIX 4.2 Release 3.2,
and will not work "as is" on previous releases, eg 3.0 or 3.1.

Using Emacstool with GNU Emacs:

   The GNU Emacs files lisp/term/sun.el, lisp/sun-mouse.el,
lisp/sun-mouse-fns.el, and src/sunfns.c provide emacs support for the
Emacstool and function keys.  If your terminal type is SUN (that is,
if your environment variable TERM is set to SUN), then Emacs will
automatically load the file lisp/term/sun.el.  This, in turn, will
ensure that sun-mouse.el is autoloaded when any mouse events are
detected.  It is suggested that sun-mouse and sun-mouse-fns be
included in your site-init.el file, so that they will always be loaded
when running on a Sun workstation.  

   The file src/sunfns.c defines several useful functions for emacs on
the Sun.  Among these are procedures to pop-up SunView menus, put and
get from the SunView selection [STUFF] buffer, and a procedure for
changing the cursor icon.  If you want to define cursor icons, try
using the functions in lisp/sun-cursors.el.

   The file lisp/sun-mouse.el includes a mass of software for defining
bindings for mouse events.  Any function can be called or any form
evaluated as a result of a mouse event.  If you want a pop-up menu,
your function can call sun-menu-evaluate.  This will bring up a
SunView walking menu of your choice.

   Use the macro (defmenu menu-name &rest menu-items) to define menu
objects.  Each menu item is a cons of ("string" . VALUE), VALUE is
evaluated when the string item is picked.  If VALUE is a menu, then a
pullright item is created.  

   This version also includes support for copying to and from the
sun-windows "stuff" selection.  The keyboard bindings defined in 
lisp/sun-mouse-fns.el let you move the current region to the "STUFF"
selection and vice versa.  Just set point with the left button, set
mark with the middle button, (the region is automatically copied to
"STUFF") then switch to a shelltool, and "Stuff" will work.  Going the
other way, the main right button menu contains a "Stuff Selection"
command that works just like in shelltool.  [The Get and Put function
keys are also assigned to these functions, so you don't need the mouse
or even emacstool to make this work.]

GNU Emacs EXAMPLES:
   See definitions in lisp/sun-mouse-fns.el for examples.

   You can redefine the cursor that is displayed in the emacs window.
On initialization, it is set to a right arrow.  See lisp/sun-cursors.el
for additional cursors, how to define them, how to edit them.

BUGS:
    It takes a few milliseconds to create a menu before it pops up.
Someone who understands the GNU Garbage Collector might see if it
is possible for defmenu to create a SunView menu struct that does
not get destroyed by Garbage Collection.

   An outline of the files used to support Sun Windows and the mouse.

etc/SUN-SUPPORT.
    This document.

etc/emacstool.1:
    Added: an nroff'able man page for emacstool.

etc/emacstool.c:
    Encodes all the function keys internally, and passes non-window 
system arguments to emacs.

etc/emacs.icon:
    The "Kitchen Sink" GNU Emacs icon.

src/sunfns.c:
    This contains the auxilary functions that allow elisp code to interact
with the sunwindows, selection, and menu functions.

lisp/sun-mouse.el:
    Defines the lisp function which is called when a mouse hit is found
in the input queue.  This handler decodes the mouse hit via a keymap-like
structure sensitive to a particular window and where in the window the
hit occured (text-region, right-margin, mode-line).  Three variables
are bound (*mouse-window* *mouse-x* *mouse-y*) and the selected function
is called. 
    See documentation on "define-mouse" or look at lisp/sun-mouse-fns.el
to see how this is done.
    Defines two functions to pass between region and sun-selection
    Defines functions for interfacing with the Menu.
During menu evaluation, the variables *menu-window* *menu-x* *menu-y* are bound.

lisp/sun-mouse-fns.el
    The definition of the default menu and mouse function bindings.

lisp/sun-cursors.el
    Defines a number of alternate cursors, and an editor for them.
    The editor is also a demonstration of mouse/menu utilization.

lisp/term/sun.el
    Sets up the keymap to make the sun function keys do useful things.
Also includes the setup/initialization code for running under emacstool,
which makes "\C-Z" just close the emacstool window (-WI emacs.icon).

Subject: Making multi-line scrolling really work:

In your .defaults file, include the line:
/Tty/Retained	"Yes"
That way, the terminal emulator can do text moves using bitblt, 
instead of repaint.

If that's not enough for you, then tell unix and emacs that 
the sun terminal supports multi-line and multi-character insert/delete.  
Add this patch to your /etc/termcap file:
