Description

bemenu is a dynamic menu for tty(4) (using ncurses(3)), X11 and Wayland, inspired by dmenu(1).

It reads a list of newline-separated items from standard input and then presents them as a list, where the user can select one or more of them. When pressing <carriage-return>, the selected items are printed to standard output (one per line) and bemenu exits.

Entering text will filter the items to those that match the input. If the number of items exceeds the size of the list, the items will be paginated.

bemenu-run is a special-case invocation of bemenu, where the input is the list of executables under PATH and the selected items are executed.

Options

-h,  --help

Print a help message to standard output and exit.

-C,  --no-cursor

Disable all cursor events.

-I,  --index <index>

-T,  --no-touch

-v,  --version

Print the bemenu version number to standard output and exit.

Always fork(2) before executing the selections. Disabled by default when using the terminal backend.

--ifne

Only display menu if there are items.

--single-instance

Force a single menu instance.

--no-exec

Print the selected items to standard output instead of executing them.

--scrollbar none|always|autohide

Specify when to show a scrollbar for vertical lists:

noneNever display a scrollbar (the default).
alwaysAlways display a scrollbar.
autohideOnly display a scrollbar when the number of items exceeds the number of lines.
-e,  --vim-esc-exits

Exit bemenu when pressing escape in normal mode for vim bindings.

-N,  --vim-normal-mode

Start in normal mode for vim bindings.

-F,  --filter

Filter items for a given string before showing the menu. Affects --ifne and --accept-single

Backend options

These options are only available on backends specified in the parentheses:

-b,  --bottom (Wayland, X11)

The list will appear at the bottom of the screen.

-c,  --center (Wayland, X11)

The list will appear at the center of the screen. (wx)

-f,  --grab (Wayland, X11)

Show the bemenu window whilst reading the items.

-B,  --border (Wayland, X11)

Specify the width of the border in pixels around the menu.

--bdr (Wayland, X11)

Specify the border color.

-R,  --border-radius (Wayland, X11)

Specify the radius of the border around the menu (0 = no curved borders).

-H,  --line-height <height> (Wayland, X11)

Specify the height in point size to make each entry.

--ch (Wayland, X11)

Specify the height of the cursor (0 = scales with line height).

--cw (Wayland, X11)

Specify the width of the cursor.

-m,  --monitor <index> (Wayland, X11)

Specify the monitor index where the list should appear. Monitor indices start at zero. The interpretation of the given argument depends on the utilized backend. With X11 and Wayland, a value of ‘-1’ or focused indicates that the current monitor should be used (the default). With Wayland, the index should be a string specifying a specific monitor name. The value ‘-2’ or all indicates that the list should appear on all monitors.

-n,  --no-overlap (Wayland)

Set the bemenu window to be on top of any other panels.

-M,  --margin <margin> (Wayland, X11)

Specify the margin (empty space) in pixels to leave between menu and vertical view borders. bemenu will reduce it's size to fit in space between gaps.

--hp (Wayland, X11)

Specify the horizontal padding for the entries in single line mode.

-W,  --width-factor <factor> (Wayland, X11)

Specify the relative width factor as a floating point number. It makes sense to set it between 0 and 1 to define how much of the screen width bemenu will use. However, bemenu will still respect margin, so if resulting size is greater than space between gaps, bemenu will ignore factor and use available space instead.

--fn <name [size]> (Wayland, X11)

Specify the font family name and size to be used. For more options, consult the Pango Reference Manual for pango_font_description_from_string().

The following options control the colours for various parts of the list for the Wayland and X11 backends. Each takes an argument in the form of:

#RGB[A]

where R, G, B and A are hexadecimal integers from 00–FF that control the red, green, blue and alpha-transparency channels.

--tb <color> Title background.

--tf <color> Title foreground.

--fb <color> Filter background.

--ff <color> Filter foreground

--cb <color> Cursor background.

--cf <color> Cursor foreground

--nb <color> Normal background.

--nf <color> Normal foreground.

--hb <color> Highlighted background.

--hf <color> Highlighted foreground.

--fbb <color> Feedback background.

--fbf <color> Feedback foreground.

--sb <color> Selected background.

--sf <color> Selected foreground.

--ab <color> Alternating background color.

--af <color> Alternating foreground color.

--scb <color> Scrollbar background.

--scf <color> Scrollbar foreground.
