Ubuntu Manpage: fuzzel - Wayland app launcher and picker

NAME

       fuzzel - Wayland app launcher and picker

SYNOPSIS

       fuzzel [OPTIONS]...

DESCRIPTION

As a launcher, fuzzel lists all available XDG applications in a searchable window.

With the --dmenu flag, fuzzel works like a general-purpose picker like dmenu, rofi or fzf. Options to
choose from are provided on the STDIN and the selected option is printed to STDOUT.

The search box supports Emacs-like key bindings.

Many things can be configured with fuzzel.ini(5) or command line options:

--config=PATH
Path to configuration file, see fuzzel.ini(5) for details.

--check-config
Verify configuration and then exit with 0 if ok, otherwise exit with 1.

--cache=PATH
Use a custom cache location. Fuzzel uses this file to cache the most commonly launched applications
(to be able to sort them at the top).

You can also use this option to enable caching of dmenu entries. It is recommended that you use a
separate cache file for each "type" of dmenu invocation; i.e. one for the browser history, another
for emojis etc.

Set to /dev/null to disable caching.

Default: XDG_CACHE_HOME/fuzzel

-o,--output=OUTPUT
Specifies the monitor to display the window on. Autocompletion is available for zsh and fish, or you
can list the available outputs with wlr-randr or with Sway using swaymsg -t get_outputs.

Example: DP-1

Default: Let the compositor choose output.

-f,--font=FONT[,FALLBACK1,FALLBACK2,...]
Comma separated list of primary font, and fallback fonts, in FontConfig format. See FONT FORMAT.
Default: monospace.

--use-bold
Allow fuzzel to use bold fonts.

-D,--dpi-aware=no|yes|auto
When set to yes, fonts are sized using the monitor's DPI, making a font of a given point size have
the same physical size, regardless of monitor.

In this mode, the monitor's scaling factor is ignored; doubling the scaling factor will not double
the font size.

When set to no, the monitor's DPI is ignored. The font is instead sized using the monitor's scaling
factor; doubling the scaling factor does double the font size.

Finally, if set to auto, fonts will be sized using the monitor's DPI if all monitors have a scaling
factor of 1. If at least one monitor as a scaling factor larger than 1 (regardless of whether the
fuzzel window is mapped on that monitor or not), fonts will be scaled using the scaling factor.

Note that this option typically does not work with bitmap fonts, which only contains a pre-defined
set of sizes, and cannot be dynamically scaled. Whichever size (of the available ones) that best
matches the DPI or scaling factor, will be used.

Also note that if the font size has been specified in pixels (:pixelsize=N, instead of :size=N), DPI
scaling (dpi-aware=yes) will have no effect (the specified pixel size will be used as is). But, if
the monitor's scaling factor is used to size the font (dpi-aware=no), the font's pixel size will be
multiplied with the scaling factor.

Default: auto

-p,--prompt=PROMPT
Prompt to use. Default: > .

--prompt-only=PROMPT
Same as --prompt, but in --dmenu mode it also:
• does not read anything from STDIN
• sets --lines to 0

In non-dmenu mode it behaves exactly like --prompt.

--placeholder=TEXT
Text to display as placeholder in the input box. Default: empty.

--search=TEXT
Initial search/filter string. This option pre-fills the input box with the specified string, letting
you pre-filter the result.

-i
Ignored; for compatibility with other, similar utilities (where -i means "case insensitive search").

--icon-theme=NAME
Icon theme to use. Note that this option is case sensitive; the name must match the theme's folder
name.

Example: Adwaita.

Default: hicolor.

-I,--no-icons
Do not render any icons.

--hide-before-typing
Hide application list until something is typed.

-F,--fields=FIELDS
Comma separated list of XDG Desktop entry fields to match against:

• filename: the .desktop file's filename
• name: the application's name (title)
• generic: the application's generic name
• exec: the applications's executable, as specified in the desktop file. Note: may include command
line options as well.
• keywords: the application's keywords
• categories: the application's categories
• comment: the application's comment

Default: filename,name,generic

--password=[CHARACTER]
Password input. Render all typed text as CHARACTER. If CHARACTER is omitted, a * will be used.

-T,--terminal=TERMINAL ARGS
Command to launch XDG applications with the property Terminal=true (htop, for example). Example:
xterm -e. Default: not set.

-a,--anchor=ANCHOR
Set window anchor, i.e. where on screen the window will be displayed. You can choose one from:

• top-left
• top
• top-right
• left
• center
• right
• bottom-left
• bottom
• bottom-right

Default: center

--x-margin=MARGIN
Horizontal margin away from the anchor point in pixels. Default: 0.

Note: this option has no effect when anchor=center, top or bottom.

--y-margin=MARGIN
Vertical margin away from the anchor point in pixels. Default: 0.

Note: this option has no effect when anchor=center, left or right.

--select=STRING
Select the first entry that matches the given string (case insensitive).

-l,--lines=COUNT
The (maximum) number of matches to display. This dictates the window height. Default: 15.

-w,--width
Window width, in characters. Margins and borders not included. Default: 30.

--tabs=COUNT
Number of spaces a tab is expanded to. Default: 8.

-x,--horizontal-pad=PAD
Horizontal padding between border and icons and text. In pixels, subject to output scaling. Default:
40.

-y,--vertical-pad=PAD
Vertical padding between border and text. In pixels, subject to output scaling. Default: 8.

-P,--inner-pad=PAD
Vertical padding between prompt and match list. In pixels, subject to output scaling. Default: 0.

-b,--background=HEX

--placeholder-color=HEX
Text (foreground) color of the placeholder string. See COLORS. Default: 93a1a1ff.

--input-color=HEX
Text (foreground) color of input string. See COLORS. Default: 657b83ff.

-m,--match-color=HEX
The color of matching substring(s). As you start typing in the search box, the matching part in each
application's name is highlighted with this color. See COLORS. Default: cb4b16ff.

-s,--selection-color=HEX
The color to use as background of the currently selected application. See COLORS. Default: eee8d5ff.

-S,--selection-text-color=HEX
The text color of the currently selected application. See COLORS. Default: 586e75ff.

-M,--selection-match-color=HEX

search box, the matching part in each application's name is highlighted with this color. See COLORS.
Default: cb4b16ff.

--counter-color=HEX
The color of the match count stats printed at the right-hand side of the input prompt. See COLORS.
Default: 93a1a1ff.

-B,--border-width=INT
The width of the surrounding border, in pixels (subject to output scaling). Default: 1.

-r,--border-radius=INT
The corner curvature, subject to output scaling. Larger means more rounded corners. 0 disables
rounded corners. Default: 10.

-C,--border-color=HEX
The color of the border. See COLORS. Default: 002b36ff.

--show-actions
Include desktop actions in the list. Desktop actions are alternative actions some desktop entries
have. Examples include "New Window", "New Document", etc.

--match-mode=exact|fzf|fuzzy
Defines how what you type is matched. See fuzzel.ini(5) for details. The default is fzf.

--no-sort
Do not sort the result.

--counter
Display the match count.

--filter-desktop=[no]
Filter the visible desktop entries based on the value of XDG_CURRENT_DESKTOP. If the optional
parameter is "no", explicitly disables filtering.

--fuzzy-min-length=VALUE
Search strings shorter than this will not by fuzzy matched. Default: 3.

--fuzzy-max-length-discrepancy=VALUE
Maximum allowed length difference between the search string, and a fuzzy match. Larger values result
in more fuzzy matches. Default: 2.

--fuzzy-max-distance=VALUE
Maximum allowed levenshtein distance between the search string, and a fuzzy match. Larger values
result in more fuzzy matches. Default: 1.

--line-height=HEIGHT
Override line height from font metrics. In points by default, but can be specified as pixels by
appending 'px' (i.e. --line-height=16px). Default: not set.

--letter-spacing=AMOUNT
Additional space between letters. In points by default, but can be specified as pixels by appending
'px' (i.e. letter-spacing=5px). Negative values are supported. Default: 0.

--layer=top|overlay
Which layer to render the fuzzel window on. Valid values are top and overlay.

top renders above normal windows, but typically below fullscreen windows and lock screens.

overlay renders on top of both normal windows and fullscreen windows. Note that the order is
undefined if several windows use the same layer. Since e.g. lock screens typically use overlay, that
means fuzzel may or may not appear on top of a lock screen.

Default: top

--no-exit-on-keyboard-focus-loss
Do not exit when losing keyboard focus. This can be useful on compositors where enabling "focus-
follows-mouse" causes fuzzel to exit as soon as the mouse is moved over another window. Sway (at
least up to, and including 1.7) exhibits this behavior.

--launch-prefix=COMMAND
Command to launch XDG applications with. If set, fuzzel will pass the Desktop File ID of the chosen
application (see the Desktop Entry specification) in the FUZZEL_DESKTOP_FILE_ID environment
variables. Default: not set.

--list-executables-in-path
Include executables from the PATH environment variable. Applies to the normal application mode, not
the dmenu mode.

--render-workers=COUNT
Number of threads to use for rendering. Set to 0 to disable multithreading. Default: the number of
available logical CPUs (including SMT). Note that this is not always the best value. In some cases,
the number of physical cores is better.

--match-workers=COUNT
Number of threads to use for matching. Set to 0 to disable multithreading. Default: the number of
available logical CPUs (including SMT). Note that this is not always the best value. In some cases,
the number of physical cores is better.

--delayed-filter-ms=TIME_MS
Time, in milliseconds, to delay refiltering when there are more matches than --delayed-filter-limit.
Default: 300.

--delayed-filter-limit=N
When there are more matches than this, switch from immediate refiltering to delayed refiltering (see
--delayed-filter-ms). Default: 20000.

-d,--dmenu
dmenu compatibility mode. In this mode, the list entries are read from stdin (newline separated). The
selected entry is printed to stdout. If the input string does not match any of the entries, the input
string is printed as is on stdout.

Alternatively, you can symlink the fuzzel binary to dmenu. Fuzzel will then start in dmenu mode,
without the --dmenu argument.

Fuzzel also supports icons, using Rofi's extended dmenu protocol. To set an icon for an entry, append
\0icon\x1f<icon-name>. Example:

echo -en "Firefox\0icon\x1ffirefox" | fuzzel --dmenu

--dmenu0
Like --dmenu, but input is NUL separated instead of newline separated. Note that in this mode, icons
are not supported.

--index
Print selected entry's index instead of its text. Index values start with zero for the first entry.
dmenu mode only.

-R,--no-run-if-empty
Exit immediately, without showing the UI, if stdin is empty. dmenu mode only.

--log-level={info,warning,error,none}
Log level, used both for log output on stderr as well as syslog. Default: warning.

--log-colorize=[{never,always,auto}]
Enables or disables colorization of log output on stderr.

--log-no-syslog
Disables syslog logging. Logging is only done on stderr.

-v,--version
Show the version number and quit

CONFIGURATION

       fuzzel will search for a configuration file in the following locations, in this order:

           •   XDG_CONFIG_HOME/fuzzel/fuzzel.ini (defaulting to ~/.config/fuzzel/fuzzel.ini if unset)
           •   XDG_CONFIG_DIRS/fuzzel/fuzzel.ini (defaulting to /etc/xdg/fuzzel/fuzzel.ini if unset)

       An  example configuration file containing all options with their default value commented out will usually
       be installed to /etc/xdg/fuzzel/fuzzel.ini.

       For more information, see fuzzel.ini(5).

LOCALIZATION

       Fuzzel uses the localized strings from the .desktop files by default. To disable this,  run  fuzzel  with
       LC_MESSAGES=C.

FONT FORMAT

       The  font  is  specified  in  FontConfig  syntax.  That  is, a colon-separated list of font name and font
       options.

       Examples:
       •   Dina:weight=bold:slant=italic
       •   Arial:size=12

COLORS

       All colors must be specified as a RGBA quadruple, in hex format, without a leading '0x'.

       EXAMPLES:
       •   white: ffffffff (no transparency)
       •   black: 000000ff (no transparency)
       •   black: 00000010 (semi-transparent)
       •   red: ff0000ff (no transparency)

       The default color scheme is Solarized.

FILES

       $XDG_CACHE_HOME/fuzzel
           Stores a list of applications and their launch count. This allows fuzzel to sort frequently  launched
           applications at the top.

       $XDG_RUNTIME_DIR/fuzzel-$WAYLAND_DISPLAY.lock
           Lock file, used to prevent multiple fuzzel instances from running at the same time.
