Path to configuration file, see fuzzel.ini(5) for details.

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

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

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.

Comma separated list of primary font, and fallback fonts, in FontConfig format. See FONT FORMAT. Default: monospace.

Allow fuzzel to use bold fonts.

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

Prompt to use. Default: > .

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.

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

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

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

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

Example: Adwaita.

Default: hicolor.

Do not render any icons.

Hide application list until something is typed.

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 input. Render all typed text as CHARACTER. If CHARACTER is omitted, a * will be used.

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

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

Horizontal margin away from the anchor point in pixels. Default: 0.

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

Vertical margin away from the anchor point in pixels. Default: 0.

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

Select the first entry that matches the given string (case insensitive).

The (maximum) number of matches to display. This dictates the window height. Default: 15.

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

Number of spaces a tab is expanded to. Default: 8.

Horizontal padding between border and icons and text. In pixels, subject to output scaling. Default: 40.

Vertical padding between border and text. In pixels, subject to output scaling. Default: 8.

Vertical padding between prompt and match list. In pixels, subject to output scaling. Default: 0.

Background color. See COLORS. Default: fdf6e3ff.

Text color. See COLORS. Default: 657b83ff.

Text (foreground) color of prompt character(s). See COLORS. Default: 586e75ff.

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

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

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.

The color to use as background of the currently selected application. See COLORS. Default: eee8d5ff.

The text color of the currently selected application. See COLORS. Default: 586e75ff.

The color of matching substring(s) of the currently selected application. 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.

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

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

The corner curvature, subject to output scaling. Larger means more rounded corners. 0 disables rounded corners. Default: 10.

The color of the border. See COLORS. Default: 002b36ff.

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

Defines how what you type is matched. See fuzzel.ini(5) for details. The default is fzf.

Do not sort the result.

Display the match count.

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

Search strings shorter than this will not by fuzzy matched. Default: 3.

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

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

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.

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.

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

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.

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.

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

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.

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.

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

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

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:

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

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

Exit immediately, without showing the UI, if stdin is empty. dmenu mode only.

Log level, used both for log output on stderr as well as syslog. Default: warning.

Enables or disables colorization of log output on stderr.

Disables syslog logging. Logging is only done on stderr.

Show the version number and quit

• 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)

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

Lock file, used to prevent multiple fuzzel instances from running at the same time.
