Worf - Wayland Optimized Run Facilitator

Worf is yet another style launcher, heavily inspired by wofi, rofi and walker. Worf is written in Rust on top of GTK4.

It started out as a drop in replacement for wofi, so styles and config in most part (should) be compatible, with a few exception documented below. Worf has more features than wofi though, so there won't be 100% compatibility. Broken compatibility with wofi is not considered a bug, but issues regarding that will be accepted if you would rather use worf than wofi.

It supports various modes:

• Math
• DRun
• File
• Ssh
• Run
• Emoji
• Auto

Auto mode tries to detect the desired mode automatically, to achieve this some modes require a prefix in the search. The standard view will show ssh and drun, for other modes the following prefixes are available:

• ssh (optional)
• ? web search
• /, $ or ~ for files

Additional functionality compared to Wofi

• Window switcher for hyprland and bitwarden client (see examples)
• All arguments expect show are supported by config and args

New config / command line options

• fuzzy-length: Defines how long a string must be to be considered for fuzzy match
• row-box-orientation: Allows aligning values vertically to place the label below the icon

Styling

Styling names and classes are inspired by wofi, so most of the documentation and styling is the same

Setup

Hyprland

Allow blur for Worf

layerrule = blur, worf

Library

The launcher and UI can be used to build any launcher, as the ui, config and run logic is available as a separate crate. This library is not available publicly yet as the interface is not stable enough.

Wofi compatibility

Breaking changes

• Runtime behaviour is not guaranteed to be the same and won't ever be, this includes error messages and themes.
• Themes in general are mostly compatible. Worf is using the same entity ids, because worf is build on GTK4 instead of GTK3 there will be differences in the look and feel.
• Configuration files are not 100% compatible, Worf is using toml files instead, for most part this only means strings have to be quoted
• Color files are not supported
• line_wrap is now called line-wrap
• Wofi has a C-API, that is not and won't be supported, but Worf can be used as a rust library.
• Most boolean options now need true or false as argument, as Worf is using the same struct for config and command line arguments and this is the only way to merge both data sources

Dropped arguments / config values

• mode, use show
• dmenu, use show
• D, arguments are the same as config in worf, no need to have this flag.
• dark, dark setting from theme is used now.
• filter-rate, worf is fast enough not to need this debounce

Dropped configuration options

• stylesheet -> use style instead
• color / colors -> GTK4 does not support color files
