# DMENU FEANOR CUSTOM BUILD
## dmenu is a dynamic menu for X, originally designed for dwm. It manages large numbers of user-defined menu items efficiently. It is a very powerful tool that allows you to pipe information into it. This makes dmenu a perfect utility to incorporate into your scripting.
## The patches used in this build include:
- dmenu-border -- adds border around dmenu window
- dmenu-center -- centers dmenu in the middle of screen (-c)
- dmenu-fuzzyhighlight -- fuzzy matches gets highlighted
- dmenu-fuzzymatch -- adds support for fuzzy-matching
- dmenu-grid -- adds a flag (-g) to specify the number of grid columns
- dmenu-lineheight -- adds a flag (-h) to set the minimum height of dmenu lines
- dmenu-morecolor -- creates a color option for use the entries adjacent to the selection
- dmenu-mousesupport -- basic mouse support
- dmenu-numbers -- Displays number of matched and total items in top right corner
- Mouse functionality
## Mouse actions supported:
- Left-mouse click:
- On prompt and input field: clear input text and selection.
- In horizontal and vertical mode on item: select and output item (same as pressing enter).
- In horizontal mode on arrows: change items to show left or right.
- Ctrl-left-mouse click: multisel modifier.
- Right-mouse click: close.
- Middle-mouse click:
- Paste current selection.
- While holding shift: paste primary selection.
- Scroll up:
- In horizontal mode: same as left-clicking on left arrow.
- In vertical mode: show items above.
- Scroll down:
- In horizontal mode: same as left-clicking on right arrow.
- In vertical mode: show items below.
## Available flags
- [-l lines]
- [-g columns]
- [-p prompt]
- [-fn font]
- [-m monitor]
- [-h height]
- [-nb color]
- [-nf color]
- [-sb color]
- [-sf color]
- [-nhb color]
- [-nhf color]
- [-shb color]
- [-shf color]
- [-w windowid]
- [-c] for centering
An example: dmenu_run -c -bw 2 -l 20 -g 4 -p 'Run: '
This launches dmenu_run with -c (centered), -bw (border width), -l (number of vertical lines) and -g (number of grid columns).
## Installing dmenu on Arch Linux
All you need to do is to download this repository. Then run the following command:
```
sudo make
sudo make clean install
```

Subject: [PATCH] Add an option which defines the lineheight
Despite both the panel and dmenu using the same font (a Terminus 12),
dmenu is shorter and the panel is visible from under the dmenu bar.
The appearance can be even more distracting when using similar colors
for background and selections. With the option added by this patch,
dmenu can be launched with a '-h 24', thus completely covering the panel.

.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 \-c
dmenu appears centered on 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 \-g " columns"
dmenu lists items in a grid with the given number of columns.
.TP
.BI \-l " lines"
dmenu lists items in a grid 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
.BI \-nhb " color"
defines the normal highlight background color.
.TP
.BI \-nhf " color"
defines the normal highlight foreground color.
.TP
.BI \-shb " color"
defines the selected highlight background color.
.TP
.BI \-shf " color"
defines the selected highlight 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

.RI [ file ...]
.SH DESCRIPTION
.B stest
takes a list of files and filters by the files' properties, analogous to
.IR test (1).
Files which pass all tests are printed to stdout. If no files are given, stest
reads files from stdin.
.SH OPTIONS
.TP
.B \-a
Test hidden files.
.TP
.B \-b
Test that files are block specials.
.TP
.B \-c
Test that files are character specials.
.TP
.B \-d
Test that files are directories.
.TP
.B \-e
Test that files exist.
.TP
.B \-f
Test that files are regular files.
.TP
.B \-g
Test that files have their set-group-ID flag set.
.TP
.B \-h
Test that files are symbolic links.
.TP
.B \-l
Test the contents of a directory given as an argument.
.TP
.BI \-n " file"
Test that files are newer than
.IR file .
.TP
.BI \-o " file"
Test that files are older than
.IR file .
.TP
.B \-p
Test that files are named pipes.
.TP
.B \-q
No files are printed, only the exit status is returned.
.TP
.B \-r
Test that files are readable.
.TP
.B \-s
Test that files are not empty.
.TP
.B \-u
Test that files have their set-user-ID flag set.
.TP
.B \-v
Invert the sense of tests, only failing files pass.
.TP
.B \-w
Test that files are writable.
.TP
.B \-x
Test that files are executable.
.SH EXIT STATUS
.TP
.B 0
At least one file passed all tests.
.TP
.B 1
No files passed all tests.
.TP
.B 2
An error occurred.
