I haven't used any kind of bar/panel for about two years now, the only things that I regularly use (that you usually would place on your panel) are date and time, but I call it from the terminal. Now I'm in the process of switching to dwm from bspwm, and I thought about hacking some small UNIX-like panel just for a change, I think lemonbar should be a good candidate (basically draws your shell scripts to a window/panel), but I now have a problem, I can't come up with the script which would update different functions at a different interval, I don't want to "curl -s ipinfo.io/ip" every 0.2sec in the main loop. I don't know how to fix this, or if this is doable in shell scripting at all, couldn't find any examples online.
