i3

A while back I posted an instruction on how to change the font size in urxvt (terminal emulator) on the fly. In that post, I used a perl extension from https://github.com/simmel/urxvt-resize-font. Tonight, I tried to setup this extension on a brand new laptop running Fedora 28. For some reason, it doesn’t work at all. Luckily, I found another perl extension which works quite well. Here’s how I got it working on this Fedora 28, with Sway tiling windows manager (instead of i3 because I run Wayland with this Fedora 28)....

urxvt or unicode-rxvt is a terminal simulator like Gnome-terminal or Konsole. Recently I’m trying to switch to use i3 (i3-gaps), a tiling windows manager, and urxvt is good compliment to i3. Unlike Gnome-terminal or Konsole, the font name and size for urxvt are configured in ~/.Xresources. To make change to font size, for example, I’d edit ~/.Xresources, reload it with xrdb ~/.Xresources, and finally close and re-open urxvt itself. Though there is no built-in function to allow changing font size on the fly, urxvt allows us to do this via extensions....
