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 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.

||||
