dmenu - dynamic menu
|
||||
====================
|
||||
dmenu is an efficient dynamic menu for X.
|
||||
|
||||
Personal Adjustments
|
||||
--------------------
|
||||
This build has a history feature, can open a terminal window
|
||||
if command ends in "!" and is adjust to fit bar padding used in dwm.
|
||||
|
||||
|
||||
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
