Although its syntax may seem strange at first, have patience;
.CW rc
was designed this way on purpose. Once its (few, but powerful) features are internalized,
.CW rc
simply gets out of the way.

Creating an

function with the same name as your prompt allows you to easily double-click to select at the end of a previously typed line and then
.CW send
it using the mouse button 2 menu (see the discussion of
.CW rio
menus, below). This can be used to approximate a form of command history (see also the commands

Add something like this to your

In
.CW rc
the
.CW ;
character forces the end of a line and is treated as a noop when it appears alone, so it is also possible to create a simple prompt that would require no special prompt function in order for the prompt to be effectively ignored when selecting and sending:
.P1
prompt=\'; \'
.P2
Obviously, the prompt can be named however the user sees fit.

.CW rio
is the Plan 9 window system. More accurately,
.CW rio
multiplexes input devices with and serves a file interface to a series of rectangles, inside the boundaries of which are drawn an arbitrary arrangement of pixels. Controlling the rectangles is more straightforward, and at the same time more flexible, than what is commonly expected from most "window managers."

To effectively use
.CW rio ,
you need a three button mouse. If you only have a two button mouse you can emulate the middle button by holding down the

Select an item by releasing the button over the menu item. Rio uses the same button that started an action throughout that operation. If you press another button during the action the operation is aborted and any intermediate changes are reversed.
Each menu acts as a action verb selector which then requires an object (i.e. window) to be picked to indicate which window the verb is to act on. A further mouse action may then be required.

.SH
8.2.2 - Window control
.R
.ihtml h3
Clicking on a window brings it to the front.
You can directly change the shape of a window by clicking and dragging on the edge or corner of the window
border. Mouse button 1 or 2 will allow you to drag the edge or corner to a new size, and mouse button 3 will allow you to
move the window.
The mouse button 3 menu contains a list of all windows that are corrently obstructed by other windows. Selecting a label tops the window.
The pop-up menu remembers the last command chosen, so as a shortcut you can just press and release button
3 without moving the mouse between pressing and releasing to select the previous command again.
In addition,
.CW rio
serves a variety of files for reading, writing, and controlling windows. Some of them are virtual versions of system files for dealing with the display, keyboard, and mouse; others control operations of the window system itself. These files, as well as the
.ihtml a <a href="http://man.9front.org/1/rio">
.CW window(1)

command, allow for controlling windows programmatically by reading and writing text strings. Thus simplifying the automated opening and placement of various windows with user scripts.

Text in a

The special file
.CW /dev/text
(for the current window), or \f(CW/dev/wsys/\fIn\f(CW/text\fR (for window \fIn\fR) contains all text that has already appeared in the window. The contents of this file may serve as a primitive form of command history (and may be acted upon using standard command line tools), but are lost when the window is closed.

By default, a

window will fill up with text and then block, obviating the need for a separate pager program (though the
.ihtml a <a href="http://man.9front.org/1/p">
.CW p(1)
.ihtml a
pager program still ships with the system).
Endless scrolling may be enabled by selecting
.CW scroll
from the mouse button 2 menu.
The
.CW up
or
.CW down
arrow keys and
.CW pgup
or
.CW pgdwn
keys may be used to scroll up or down in consistently measured increments.
Holding down the
.CW shift
key and pressing the up or down arrow key will scroll a single line in the respective direction.
9front's
.CW rio
supports mousewheel scrolling. The heuristic employed is roughly the same as that of clicking in the scrollbar on the left of the window: when the mouse pointer is near the top of the window the scrolling increment is small, while as the mouse pointer approaches the bottom of the window the scrolling increment grows progressively larger. Presently this behavior is limited to
.CW rio ,
.CW sam ,
and
.CW mothra
but may later be extended to other programs.
.B Note:
While the behavior of the arrow and page keys is fairly consistent between programs, mousewheel scrolling is not. So far,
.CW shift
+
.CW up
or
.CW down
is only supported in
.CW rio
windows.

Rob Pike,

.QS
the clean appearance of the screen comes mostly from laziness, but the
color scheme is (obviously) deliberate. the intent was to build on an
observation by edward tufte that the human system likes nature and
nature is full of pale colors, so something you're going to look at all day
might best serve if it were also in relaxing shades. renee french helped me with
the specifics of the color scheme (she's a professional illustrator and my
color vision is suspect), once i'd figured out how i wanted it to look.
there are still some features of the color system that i put in that i think no
one has ever noticed. that's a good thing, in my opinion; the colors should
fade away, if you'll pardon the expression. having used other systems with
different approaches to color screens, most especially windows XP (extra pukey),
i think tufte was right.

The color scheme was an attempt to honor a point made originally

> functioning cursor keys would still be a speed benefit.
This feels true but is false. There were some fascinating experiments
done a few years ago in which people were given a long, tedious
editing task. Some of the people were keyboard fans, some were mouse
fans. Both folks were asked to do the task two ways, in random order,
once using the mouse to do the editing, once using cursor keys etc.
Regardless of their predilections, which was stated up front, after
the experiment everyone who did the task agreed that it was faster to
use the keyboard than the mouse to complete the task. Everyone.
Here's the kicker: everyone was wrong. They were being timed, and in
fact the reverse was true. Although they thought the keyboard was
faster, doing the task using the mouse was faster for everyone, by a
substantial fraction.
The explanation, besides the obvious that arrow keys are actually
pretty slow if you're going more than a line or character, is that
people feel the mouse wastes time because you need to grab it and move
it, but it's time well spent. The part of the brain that uses
keyboard commands to move the cursor is a higher-order function, and
thinking and planning how to use the keys to get to the destination
blocks thinking about the editing task at hand. But using the mouse
is done by a lower-order part of the brain, which keeps the editing
part of the brain clear. There's less task switching going on when
you use the mouse, so you work more efficiently.
If you don't believe me, the story is here:
http://www.asktog.com/readerMail/1999-12ReaderMail.html
Thanks to some forgotten 9fan who mentioned this a while back.
I didn't know about these experiments when I said, long ago, that
using arrow keys to point at a display is like telling someone how to
go somewhere by giving directions, while using a mouse is like
pointing at a map. In fact, I never used a screen editor until I had
a mouse, for just this reason.

8.4.7 - secstore
.R
.ihtml h3
Typing in lots of passwords over and over again is annoying.
Secstore authenticates to a secure-store server using a
password and optionally a hardware token, then saves or
retrieves a file. This is intended to be a credentials
store (public/private keypairs, passwords, and other
secrets) for a
.CW factotum .

FQA 7.4.3.1 - Adding users to secstore
.R
.ihtml a
to add users.
Once a user has been added to
.CW secstored ,
the user may add to the file read by
.CW factotum
at startup. To do so, open a new window and type
.P1
% ramfs -p; cd /tmp
% auth/secstore -g factotum
secstore password: [user's secstore password]
% echo \'key proto=apop dom=x.com user=ehg !password=hi\' >> factotum
% auth/secstore -p factotum
secstore password: [user's secstore password]
% read -m factotum > /mnt/factotum/ctl
.P2
and delete the window. The first line creates an ephemeral
memory-resident workspace, invisible to others and automatically
removed when the window is deleted. The next three
commands fetch the persistent copy of the secrets, append a
new secret, and save the updated file back to secstore. The
final command loads the new secret into the running
.CW factotum .
The
.CW ipso
command packages this sequence into a convenient
script to simplify editing of files stored on a secure
store. It copies the named files into a local
.CW ramfs
and
invokes
.CW \$editor
on them. When the editor exits,
.CW ipso
prompts the user to confirm copying modifed or newly created
files back to secstore. If no file is mentioned,
.CW ipso
grabs all the user's files from secstore for editing.
By default,
.CW ipso
will edit the secstore files and, if one of
them is named factotum, flush current keys from
.CW factotum
and load the new ones from the file.

.CW linuxemu
is a program that can execute Linux/i386 ELF binaries on Plan 9. Semi-modern web browsers and other Linux programs may be run using
.CW linuxemu
(if necessary, in conjunction with the
.CW equis
X11 server).
.html - <p>Download it here: <a href="http://plan9.stanleylieber.com/src/linuxemu3.tgz">linuxemu3.tgz</a><p>The equis X11 server is available from <a href="http://9front.org/extra/">9front.org/exra/</a>, or <a href="http://www.quanstro.net/magic/man2html/1/contrib">contrib(1)</a>).
.B Note:
.CW linuxemu
can only be run on a Plan 9 system booted with a
.CW 386
kernel and binaries.
BOOTSTRAP
To run
.CW linuxemu ,
you need a Linux root file system packed into a tarball:
.ihtml a <a href="http://felloff.net/usr/cinap_lenrek/mroot-linuxemu.tbz">
http://felloff.net/usr/cinap_lenrek/mroot-linuxemu.tbz
.ihtml a
.ihtml a <a href="http://plan9.stanleylieber.com/linuxemu/mroot.tgz">
http://plan9.stanleylieber.com/linuxemu/mroot.tgz
.ihtml a
The
.CW mroot-linuxemu.tbz
version contains no symlinks and can be extracted with plain Plan 9 tools
.CW bunzip
and
.CW tar .
The
.CW mroot.tgz
version contains the same Debian Sarge base as
.CW mroot-linuxemu.tbz ,
but with several additional packages pre-installed:
.ihtml ul <ul>
.IP
9base
dmenu-4.1.1
dwm-5.8.2
gcc 3.3.5
linux-kernel-headers
mercurial 0.9.4
opera 10.11
python 2.3.5
xlib-dev
.LP
.ihtml ul
and more.
You can create your own
.CW mroot
with
.CW debootstrap
on Debian Linux, or help write an installer that unpacks and installs an alternative distribution on Plan 9... In any case,
.CW linuxemu
is not hardwired to any Linux distribution!
RUNNING
Use the provided
.CW linux
script to chroot into your Linux
.CW mroot .
The
.CW linux
script is neccesary because for Linux programs to run, shared
libraries from your
.CW mroot
have to appear in its
.CW /lib
and
.CW /usr/lib
directories, while configuration files are expected to be in
.CW /etc .
The script will build a private namespace and then bind the Linux
.CW mroot
over the Plan 9 root. The original Plan 9 namespace is mounted within
.CW linuxemu
under
.CW /9 .
Assuming
.CW mroot
is located in the current directory, start
.CW linuxemu
like this:
.P1
linux -r ./mroot /bin/bash -i
.P2
If the
.CW -r
option is omitted, the Linux
.CW mroot
defaults to
.CW /sys/lib/linux
on the Plan 9 machine.
In the Linux
.CW mroot ,
.CW /etc/resolv.conf
should be changed to match your network nameserver. In addition,
.CW /etc/apt/sources.list
should be updated to a working Debian mirror. Sarge packages can still be accessed at:
.CW
deb http://archive.debian.org/debian-archive/debian sarge main
.R
EXAMPLES
Linux X11 programs may be used in conjunction with the
.CW equis
X11 server. For example, to run the Opera web browser under your Linux
.CW mroot ,
start
.CW equis
in a
.CW rio
window, start
.CW linuxemu
in another
.CW rio
window and then from within
.CW linuxemu :
.P1
dwm & # X11 window manager
opera & # web browser
.P2
Opera should (eventually) appear in the
.CW equis
window. A window manager (this example uses dwm) is recommended so that X11 programs interact with window resources properly.
DEBUGGING
If
.CW linuxemu
crashes, use acid to figure out whats going on:
.P1
mk acid
acid -l linuxemu.acid <pid>
.P2
Then you can issue the following commands:
.P1
ustk()
.P2
dump a (userspace) stacktrace for the current thread:
.P1
umem(Current()) dump the memory mappings
ufds(Current()) dump the filedescriptor table
utrace(Current()) dump the internal tracebuffer
(enabled by -d option)
.P2
Use
.CW xasm()
and
.CW xcasm()
for disassembly for Linux code.
Read:
.ihtml a <a href="http://man.9front.org/1/acid">
.CW acid(1)
.ihtml a
You can also enable full trace logging:
.P1
linux -r ./mroot -dd /bin/bash -i >[2]/tmp/linuxemu.log
.P2
This slows
.CW linuxemu
down considerably. In case of race conditions, it often happens that the bug disapears when doing full trace logging!

.ihtml h3
ACPI is enabled with the presence of
.CW *acpi=
boot parameter.
This will create the
.CW /dev/acpitbls
file that can be used to read the systems acpi tables. Specifying
.CW *acpi=0
will make acpi tables accessible thru the file but not use it in the kernel.

More than one person has claimed to have ported

to Plan 9, but no code has ever been made public. Please stop telling unsuspecting newbs that
.CW git
is available for Plan 9.
In the meantime, someone wrote a shell script wrapper that attempts to replicate some basic
.CW git
actions by downloading a zip file from the repository and performing operations on it.
