1dwm - dynamic window manager
2----------------------------
3dwm is an extremely fast, small, and dynamic X11 window manager.
4
5
6Requirements
7------------
8In order to build dwm you need the Xlib header files.
9
10
11Installation
12------------
13Edit config.mk to match your local setup (dwm is installed into
14the /usr/local namespace by default).
15
16Afterwards enter the following command to build and install dwm (if
17necessary as root):
18
19 make clean install
20
21
22Running dwm
23-----------
24Add the following line to your .xinitrc to start dwm using startx:
25
26 exec dwm
27
28In order to connect dwm to a specific display, make sure that
29the DISPLAY environment variable is set correctly, e.g.:
30
31 DISPLAY=foo.bar:1 exec dwm
32
33(This will start dwm on display :1 of the host foo.bar.)
34
35In order to display status info in the bar, you can do something
36like this in your .xinitrc:
37
38 while true
39 do
40 echo `date` `uptime | sed 's/.*://; s/,//g'`
41 sleep 1
42 done | dwm
43
44
45Configuration
46-------------
47The configuration of dwm is done by creating a custom config.h
48and (re)compiling the source code.

1.TH DMENU 1 d-0.0
2.SH NAME
3dmenu \- dynamic menu
4.SH SYNOPSIS
5.B dmenu
6.RB [ \-v ]
7.RB [ \-t
8.IR title ]
9.SH DESCRIPTION
10.SS Overview
11.B dmenu
12is a generic, highly customizable, and efficient menu for the X Window System,
13originally designed for
14.BR dwm (1).
15It supports arbitrary, user defined menu contents.
16.SS Options
17.TP
18.B \-v
19prints version information to stdout, then exits.
20.TP
21.BI \-t " title"
22displays
23.I title
24above the menu.
25.SS Usage
26.B dmenu
27reads a list of newline-separated items from stdin and creates a menu.
28When the user selects an item or enters any text and presses Enter, his choice
29is printed to stdout and
30.B dmenu
31terminates.
32.SS Keyboard Control
33.B dmenu
34is completely controlled by the keyboard. The following keys are recognized:
35.TP 2
36Any printable character
37appends the character to the text in the input field. This works as a filter:
38only items containing this text will be displayed.
39.TP 2
40Left/Right (Control-p/Control-n)
41select the previous/next item.
42.TP 2
43Tab (Control-i)
44copy the selected item to the input field.
45.TP 2
46Enter (Control-j)
47confirm selection and quit (print the selected item to stdout).
48.TP 2
49Shift-Enter (Shift-Control-j)
50confirm selection and quit (print the text in the input field to stdout).
51.TP 2
52Escape (Control-[)
53quit without selecting an item.
54.TP 2
55Backspace (Control-h)
56remove enough characters from the input field to change its filtering effect.
57.TP 2
58Control-u
59remove all characters from the input field.
60.SS Exit codes
61.B dmenu
62returns
63.B 0
64if Enter is pressed on termination,
65.B 1
66if Escape is pressed.
