I needed a decent calculator emulator 🌈 on the command-line, to invoke via i3wm. I haven't found anything so far. But I guess xcalc will have to do for now.
Here is a collection of some themes for the x.org calculator, still very crude!
All questions regarding xcalc should be directed at the Xorg mailing list
The xcalc code repository can be found at freedesktop.org
-
place themes in .xres or anywhere else you wish.
-
call them by placing something like this inside your .Xresources
! SOURCE PROGRAM SPECIFIC FILES !
#include "/home/<user>/.xres/xcalc/theme1"
- Remember to invoke xrdb
xrdb .Xresources
