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. | |||||
