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. | |||
