There is a lot you can do just with rofi … yes, this fork works with Wayland, and with a just a bit of gluing together, you can get completely functional applications … e.g., https://github.com/svenstaro/rofi-calc, I am in the process (patches welcome!) with writing a pinentry program just with bash at https://git.sr.ht/~mcepl/pinentry-rofi (for some reasons all pinentry programs are written in something weird, so it pulls unwanted dependencies to the host system on MicroOS).

I’m sure most folks are aware of the list on Are we Wayland yet?, which has a lot of great apps. Most of the standard desktop ones are already included with Manjaro Sway edition. However, one glaring omission was a calculator app (bc is of course included and usable on the terminal, but can be rather cumbersome for complex calculations).

Today, I stumbled across a very nice alternative: speedcrunch. So far it’s been working great natively on Sway thanks to being based on the latest qt5-tools. Nice fast keyboard-based interface with the option to use a GUI keypad, binary (“Bitfield”) input, support for expressions, functions, mathematical constants, smart completion, complex numbers, and more!

Really much happier with this app when compared to the more basic gnome-calculator, and even GNU bc (“basic calculator” or “bash calc” as I like to call it).
