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.

dmenu \- dynamic menu

.RB [ \-w
.IR windowid ]
.P
.BR dmenu_run " ..."
.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 \-b
dmenu appears at the bottom of the screen.
.TP
.B \-f
dmenu grabs the keyboard before reading stdin if not reading from a tty. This
is faster, but will lock up X until stdin reaches end\-of\-file.
.TP
.B \-i
dmenu matches menu items case insensitively.
.TP
.BI \-l " lines"
dmenu lists items vertically, with the given number of lines.
.TP
.BI \-h " height"
dmenu uses a menu line of at least 'height' pixels tall, but no less than 8.
.TP
.BI \-m " monitor"
dmenu is displayed on the monitor number supplied. Monitor numbers are starting
from 0.
.TP
.BI \-p " prompt"
defines the prompt to be displayed to the left of the input field.
.TP
.BI \-fn " font"
defines the font or font set used.
.TP
.BI \-nb " color"
defines the normal background color.
.IR #RGB ,
.IR #RRGGBB ,
and X color names are supported.
.TP
.BI \-nf " color"
defines the normal foreground color.
.TP
.BI \-sb " color"
defines the selected background color.
.TP
.BI \-sf " color"
defines the selected foreground color.
.TP
.B \-v
prints version information to stdout, then exits.
.TP
.BI \-w " windowid"
embed into windowid.
.SH USAGE
dmenu is completely controlled by the keyboard. Items are selected using the
arrow keys, page up, page down, home, and end.
.TP
.B Tab
Copy the selected item to the input field.
.TP
.B Return
Confirm selection. Prints the selected item to stdout and exits, returning
success.
.TP
.B Ctrl-Return
Confirm selection. Prints the selected item to stdout and continues.
.TP
.B Shift\-Return
Confirm input. Prints the input text to stdout and exits, returning success.
.TP
.B Escape
Exit without selecting an item, returning failure.
.TP
.B Ctrl-Left
Move cursor to the start of the current word
.TP
.B Ctrl-Right
Move cursor to the end of the current word
