.TH WMIIMENU 1 wmii-4
.SH NAME
wmiimenu \- window manager improved 2 menu
.SH SYNOPSIS
.B wmiimenu
.RB [ \-v ]
.RB [ \-t
.IR title ]
.SH DESCRIPTION
.SS Overview
.B wmiimenu
is a generic, highly customizable, and efficient menu for the X Window System,
originally designed for
.BR wmii (1).
It supports arbitrary, user defined menu contents.
.SS Options
.TP
.B \-v
prints version information to stdout, then exits.
.TP
.BI \-t " title"
displays
.I title
above the menu.
.SS Usage
.B wmiimenu
reads a list of newline-separated items from stdin and creates a menu.
When the user selects an item or enters any text and presses Enter, his choice
is printed to stdout and
.B wmiimenu
terminates.
.SS Keyboard Control
.B wmiimenu
is completely controlled by the keyboard. The following keys are recognized:
.TP 2
Any printable character
appends the character to the text in the input field. This works as a filter:
only items containing this text will be displayed.
.TP 2
Left/Right (Control-p/Control-n)
select the previous/next item.
.TP 2
Tab (Control-i)
copy the selected item to the input field.
.TP 2
Enter (Control-j)
confirm selection and quit (print the selected item to stdout).
.TP 2
Shift-Enter (Shift-Control-j)
confirm selection and quit (print the text in the input field to stdout).
.TP 2
Escape (Control-[)
quit without selecting an item.
.TP 2
Backspace (Control-h)
remove enough characters from the input field to change its filtering effect.
.TP 2
Control-u
remove all characters from the input field.
.SS Exit codes
.B wmiimenu
returns
.B 0
if Enter is pressed on termination,
.B 1
if Escape is pressed.
.SH ENVIRONMENT
.TP
WMII_FONT
The X11 font used to display each item in the menu.
.br
Default: fixed
.TP
WMII_NORMCOLORS
The foreground, background, and border colors of a label. Syntactically, three blank-separated color values of the form #RRGGBB are expected.
.br
Default: #222222 #eeeeee #666666
.TP
WMII_SELCOLORS
Like WMII_NORMCOLORS, but for the selected label.
.br
Default: #ffffff #335577 #447799

.TH WMIIR 1 wmii-4
.SH NAME
wmiir \- window manager improved 2 remote
.SH SYNOPSIS
.B wmiir
.RB [ \-a
.IR address ]
.I action
.I file
.br
.B wmiir
.B \-v
.SH DESCRIPTION
.SS Overview
.B wmiir
is a client to access the filesystem of
.BR wmiiwm (1)
from the command line or from shell
scripts. It can be used to configure
.BR wmii (1).
.SS Options
.TP
.BI \-a " address"
Lets you specify the address to which
.B wmiir
will establish a connection. If this option is not supplied, and the
environment variable WMII_ADDRESS is set,
.B wmiir
will use this value as its address. Currently, the address can only be a
unix socket file or a tcp socket. The syntax for
.I address
is taken (along with many other profound ideas) from the Plan 9 operating
system and has the form
.BR unix!/path/to/socket
for unix socket files, and
.BR tcp!hostname!port
for tcp sockets.
.TP
.B \-v
Prints version information to stdout, then exits.
.TP
The syntax of the actions is as follows:
.TP
.B write
Writes the supplied data from stdin to
.IR file,
overwriting any previous data. The data to be written is arbitrary
and only gains meaning (and restrictions) when it is interpreted by
.BR wmiiwm (1).
See
.B EXAMPLES
below.
.TP
.B create
Creates file or directory but does not write any data. If the file exists,
nothing is done.
.TP
.B read
Reads file or directory contents
.TP
.B remove
Removes file or directory tree
.SH ENVIRONMENT
.TP
WMII_ADDRESS
See above.
.SH EXAMPLES
.TP
.B wmiir read /
This prints the root directory of the wmii filesystem. For more information
about the contents of this filesystem, see
.BR wmiiwm (1).
.TP
.B echo -n quit | wmiir write /ctl
Write 'quit' to the main control file of the wmii filesystem, effectively
leaving wmii.
.TP
.B echo -n view 2 | wmiir write /ctl
Bring into view all clients tagged '2'. To learn about clients and
tags, see
.BR wmiiwm (1).

\title{Improved GUI concepts for experienced users}
\author{Anselm R. Garbe\\ \small garbeam at gmail dot com}
\maketitle \thispagestyle{empty}
\begin{abstract}
This article presents the motivation and concepts of the dynamic
window manager wmii and the graphical toolkit liblitz for the
\it{X Window System}.
\end{abstract}
%-------------------------------------------------------------------------
\section{Motivation}
Most common graphical user interfaces are designed after the WIMP\cite{wimp}
paradigm, which has dominated the desktop environment
landscape since late 1980s. While research has been done on alternative
user interfaces, often the focus targeted more in ease of use and low
learning curves for new computer users rather than in efficiency and
power of abstraction.
The main reason has been the economical success of computers
in the normal consumer market, which consists of unexperienced users mainly.
Our motivation is to change this situation and to provide a graphical
user interface for experienced users, though we know that this market is
a niche.
There has been done rarly research in the non-wimp GUI landscape for years.
Back in 80s and early 90s there has been some research in
this area for the Plan 9\cite{plan9} operating system at Bell Labs.
Most recent research has been done by individuals only, like Tuomo Valkonen with
his Ion\cite{ion} project and Lars Bernhardsson with his
LarsWM\cite{larswm} project.
The approaches found in the Plan 9 operating system are interesting, because
on the one hand they cancelled the Unix tradition to work in Teletype emulators
and on the other hand, they didn't followed the WIMP paradigm propagated by Apple,
IBM or Microsoft. This makes Plan 9 the most unique approach compared to the
classical WIMP world.
The main aspects of an improved GUI consists of two things, a powerful
window management approach and a sane and simple widget set which fits well
into this window management approach.
In the area of improved window management concepts there has been done more
research, thus there appeared several different approaches. But the area
of improved widget sets which form powerful applications with a simple widget
set has been ignored for long time. Instead, the WIMP world introduced many
widgets which seem to focus on eye-candy, like progress bars, but don't
fix the essential problems with WIMP toolkits.
