dwm - dynamic window manager |
||||
---------------------------- |
||||
dwm is an extremely fast, small, and dynamic X11 window manager. |
||||
|
||||
|
||||
Requirements |
||||
------------ |
||||
In order to build dwm you need the Xlib header files. |
||||
|
||||
|
||||
Installation |
||||
------------ |
||||
Edit config.mk to match your local setup (dwm is installed into |
||||
the /usr/local namespace by default). |
||||
|
||||
Afterwards enter the following command to build and install dwm (if |
||||
necessary as root): |
||||
|
||||
make clean install |
||||
|
||||
|
||||
Running dwm |
||||
----------- |
||||
Add the following line to your .xinitrc to start dwm using startx: |
||||
|
||||
exec dwm |
||||
|
||||
In order to connect dwm to a specific display, make sure that |
||||
the DISPLAY environment variable is set correctly, e.g.: |
||||
|
||||
DISPLAY=foo.bar:1 exec dwm |
||||
|
||||
(This will start dwm on display :1 of the host foo.bar.) |
||||
|
||||
In order to display status info in the bar, you can do something |
||||
like this in your .xinitrc: |
||||
|
||||
while true |
||||
do |
||||
echo `date` `uptime | sed 's/.*://; s/,//g'` |
||||
sleep 1 |
||||
done | dwm |
||||
|
||||
|
||||
Configuration |
||||
------------- |
||||
The configuration of dwm is done by creating a custom config.h |
||||
and (re)compiling the source code. |

.SH NAME |

dmenu \- dynamic menu |
||||
.SH SYNOPSIS |
||||
.B dmenu |
||||
.RB [ \-v ] |
||||
.RB [ \-t |
||||
.IR title ] |
||||
.SH DESCRIPTION |
||||
.SS Overview |
||||
.B dmenu |
||||
is a generic, highly customizable, and efficient menu for the X Window System, |
||||
originally designed for |
||||
.BR dwm (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 dmenu |
||||
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 dmenu |
||||
terminates. |
||||
.SS Keyboard Control |
||||
.B dmenu |
||||
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 dmenu |
||||
returns |
||||
.B 0 |
||||
if Enter is pressed on termination, |
||||
.B 1 |
||||
if Escape is pressed. |
||||
