+# Luke's dmenu
+
+Extra stuff added to vanilla dmenu:
+
+- reads Xresources (ergo pywal compatible)
+- alpha patch, which importantly allows this build to be embedded in transparent st
+- can view color characters like emoji (libxft-bgra is required for this reason)
+- `-P` for password mode: hide user input
+- `-r` to reject non-matching input
+- dmenu options are mouse clickable
+
+## Installation
+
+You must have `libxft-bgra` installed until the libxft upstream is fixed.
+
+After making any config changes that you want, but `make`, `sudo make install` it.

+.RB [ \-w

+.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
+.B \-P
+dmenu will not directly display the keyboard input, but instead replace it with dots. All data from stdin will be ignored.
+.TP
+.B \-r
+dmenu will reject any input which would result in no matching option left.
+.TP
+.BI \-l " lines"
+dmenu lists items vertically, with the given number of lines.
+.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

+.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.
