Application launcher yofi configuration

Application launcher (application launcher), usually used to quickly locate and launch other programs in the computer. For example, Albert Launcher and Synapse in Linux, Alfred in macOS, etc. After pressing the Super shortcut key in the Gnome environment, the function is similar.

The launcher generally has a fuzzy search function. This article introduces yofi, a lightweight launcher written in rust and suitable for the wanyland environment. The popularity of rust writing has increased, and the author is still actively maintaining it. At present, it seems that not many people use it. When I wrote this article, Google couldn’t find relevant information in Chinese, so I accidentally filled the gap in the Chinese world. I did a little bit of work, and my merit +1.

1. Download, compile and install

  • Download the source code
1 git clone
  • Compile and install

The application of rust, cargo compilation, save worry and effort, just wait for the executable file to be generated. The generated binary is in the target/release/ directory,

1➜ cargo run --release
2➜ yofi git:(master) ls
3  Cargo.lock Cargo.toml flake.lock flake.nix LICENSE rust-toolchain src target
4➜ yofi git:(master) ls -al target/release/yofi
5  -rwxrwxr-x 2 mephisto mephisto 11454816 Mar 17 14:54 target/release/yofi
6➜ yofi git:(master) file target/release/yofi
7  target/release/yofi: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/, BuildID[sha1]=83e34f2d6952622f6767b088083ed045c5 3ca4df, for GNU/Linux 3.2.0, with debug_info, not stripped
  • make a soft link

Convenience for subsequent upgrades

1sudo ln -s /home/mephisto/github/yofi/target/release/yofi /usr/bin/yofi
  • Bind a shortcut key

If you are in the Gnome environment: Settings/Keyboard/Coustom Shortcuts Set shortcut keys according to your preferences.


Gnome yofi settings

Press F8 to search and start the corresponding program, and the ones with the highest frequency of use will be displayed first.

Gnome yofi

If you are a Sway environment:

1➜ ~ grep yofi ~/.config/sway/config
2     #yofi lancher
3     bindsym F8 exec yofi apps

It means to bind the F8 shortcut key to execute the yofi apps command


sway yofi

I mainly use Gnome and sway two environments, others will not be introduced.

Some readers may have doubts, since Gnome's Super key has a similar effect, why bother. Sir, this is wrong. Not everyone uses Gnome. For example, when using the sway environment, Gnome is not easy to customize. You can change it as you want, and there are functions such as blacklist. For details, refer to [yofi wiki](https:/ /

2. Personalized configuration

Mainly customize the style after yofi calls out, such as window size, font, rounded corners, and color.

Remember to find a good-looking icon set, it is definitely worth it, and the appearance is also very important. I chose Papirus because it looks good, and there are many and complete icons.

Personal Configuration is for reference only:

  1➜  ~ cat ~/.config/yofi/yofi.config  
  2# Width/height of the app in pixels
  3width = 800  
  4height = 512
  6# If set forces usage of basic window instead of Layer Shell wayland protocol
  7force_window = false
  9# if unset, renders window centered
 10# window_offsets = [500, -50] # in format [top_offset_pixels, left_offset_pixels]
 12# Similar to CSS border-radius for main window, for more details see corner_radius
 13# for [input_text]
 14corner_radius = "0"
 16# font = "DejaVu Sans"

 55# Corner radius is the arc radius for the surrounding input box.
 56# Similar to border-radius in CSS but only in pixels.

 96theme = "Papirus"
