dmenu - dynamic menu
 | 
			
		||||
====================
 | 
			
		||||
dmenu is an efficient dynamic menu for X.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
Requirements
 | 
			
		||||
------------
 | 
			
		||||
In order to build dmenu you need the Xlib header files.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
Installation
 | 
			
		||||
------------
 | 
			
		||||
Edit config.mk to match your local setup (dmenu is installed into
 | 
			
		||||
the /usr/local namespace by default).
 | 
			
		||||
 | 
			
		||||
Afterwards enter the following command to build and install dmenu
 | 
			
		||||
(if necessary as root):
 | 
			
		||||
 | 
			
		||||
    make clean install
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
Running dmenu
 | 
			
		||||
-------------
 | 
			
		||||
See the man page for details.

.SH DESCRIPTION
 | 
			
		||||
.B dmenu
 | 
			
		||||
is a dynamic menu for X, which reads a list of newline\-separated items from
 | 
			
		||||
stdin.  When the user selects an item and presses Return, their choice is printed
 | 
			
		||||
to stdout and dmenu terminates.  Entering text will narrow the items to those
 | 
			
		||||
matching the tokens in the input.
 | 
			
		||||
.P
 | 
			
		||||
.B dmenu_run
 | 
			
		||||
is a script used by
 | 
			
		||||
.IR dwm (1)
 | 
			
		||||
which lists programs in the user's $PATH and runs the result in their $SHELL.
 | 
			
		||||
.SH OPTIONS

.TP

.B \-f

		||||
is faster, but will lock up X until stdin reaches end\-of\-file.
 | 
			
		||||
.TP
 | 
			
		||||
.B \-i
 | 
			
		||||
dmenu matches menu items case insensitively.

		||||
.TP
 | 
			
		||||
.BI \-sf " color"
 | 
			
		||||
defines the selected foreground color.
 | 
			
		||||
.TP
 | 
			
		||||

Files which pass all tests are printed to stdout. If no files are given, stest
 | 
			
		||||
reads files from stdin.
