9wm Version 1.1
Copyright 1994 David Hogan.
What is 9wm?
9wm is an X window manager which attempts to emulate the Plan 9 window
manager 8-1/2 as far as possible within the constraints imposed by X.
It provides a simple yet comfortable user interface, without garish
decorations or title-bars. Or icons. And it's click-to-type. This
will not appeal to everybody, but if you're not put off yet then read
on. (And don't knock it until you've tried it).
One major difference between 9wm and 8-1/2 is that the latter provides
windows of text with a typescript interface, and doesn't need to run a
separate program to emulate a terminal. 9wm, as an X window manager,
does require a separate program. For better 8-1/2 emulation, you should
obtain Matthew Farrow's "9term" program (ftp://ftp.cs.su.oz.au/matty/unicode),
version 1.6 or later (earlier versions don't cooperate with 9wm in
implementing "hold mode"). Of course, you can run xterm under 9wm as well.
What is 9wm not?
9wm is not a virtual window manager. It is not customisable to any
great extent. It is not large and unwieldy, and doesn't use the X
toolkit. Requests to make it any of these things will be silently
ignored (or flamed if I have had a bad day :-) If you want tvtwm
or mwm, you know where to get them...
Where do I get it?
The latest version of 9wm is held at ftp://ftp.cs.su.oz.au/dhog/9wm
9wm was written by David Hogan (firstname.lastname@example.org), a postgraduate
student at the Basser Department of Computer Science, University
of Sydney (http://www.cs.su.oz.au/basser_home.html).

How do I compile/install it?
Assuming your system is correctly configured, you should only need to
run xmkmf to generate the Makefile, and then run make or make install.
make install.man should copy the manpage (9wm.man) to the appropriate
If the make fails, complaining that the function _XShapeQueryExtension
does not exist, try removing the "-DSHAPE" from the Imakefile, and
run xmkmf and make again.
If you don't have imake, or it is misconfigured, or you would prefer
not to use it, try copying the file "Makefile.no-imake" to "Makefile",
then edit the definitions in this Makefile to suit your system. This
may require defining suitable compilation flags for your system
(normally imake does this for you). For instance, on AIX you must
include "-DBSD_INCLUDES" in CFLAGS.
How do I use it?
See the manual page for details. You should probably read the
man page for 9term as well.
What if I find a bug?
Please mail all bug reports to email@example.com, so
that I can incorporate fixes into the next release. If you can
tell me how to fix it, all the better.
9wm tries hard to emulate 8-1/2, but isn't 100% compatible. If
you are an experienced 8-1/2 user, please be patient with it.
Multi-screen displays (aka "Zaphod Mode") are not supported. Fixing
this requires major changes to the source, so don't expect to see
this fixed for some time.
One intentional difference between 9wm and 8-1/2 is in the behaviour
of the menu when the last hidden item is unhidden. Under 8-1/2, when
the menu is next used, it pops up with "New" selected. Under 9wm,
the (new) last menu item will be selected. This is a feature. It
may be confusing if you frequently switch between 9wm and 8-1/2.
If you don't like this feature, email me for the one line fix.
There have been some problems encountered when resizing 9term on
some platforms. This turns out to be a problem in 9term (actually
in libXg, to be precise). Newer versions of 9term should be
immune to this, see firstname.lastname@example.org if your 9term needs fixing.
Some client programs do wierd things. One of these is Frame Maker.
It appears that if it has a modal dialog on the screen, then if any
of its windows are current, all keypresses are redirected to the
modal dialog. This is not 9wm's fault -- Frame Maker is doing this.

Thanks to Rob Pike for writing the original 8-1/2 program (and
before that, mux) which inspired the writing of 9wm.
Thanks to John Mackin, whose gwm "wool code" for emulating mux
was also an inspiration: I used it (and hacked it) until I got
too frustrated with gwm's large memory requirements and lack of
speed (sorry Colas!), and decided to write a dedicated program.
Thanks to Matthew Farrow for writing 9term.
