That allows you to not run unnecessary parts of your script for better performance.
For example, Argos has an environment variable that tells you if the widget is open or not. There are also some differences compared to Argos. However…Ĭolors don’t seem to work on the dropdown menus, which may be the desktop manager forcing theme colors, so your mileage might vary. A small button will let you open network management. It will turn color if it is slow or unable to ping. Now you’ll get a ping time from Google on your bar. # get an integer to compare (bash doesn't like floats)Įcho ": $OUTPUT ms | refresh=true color=$COLOR" bash="'/usr/bin/systemsettings kcm_networkmanagement'" terminal=false OUTPUT=$( ping -c 1 -q | grep ^rtt | cut -d ' ' -f 4 | cut -d '/' -f 1 )Įcho "Error click to refresh | refresh=true color=orange" bash="'/usr/bin/systemsettings kcm_networkmanagement'" terminal=false Suppose you want to ping google on demand. You can also add a r efresh=true attribute to a text line to make clicking it run the script again. For example, a script of will run every 10 seconds but haddemo.2m.sh will run every two minutes. You can also name the script with a repeat interval. If you set a refresh interval on the configuration screen, the script will run that often. Of course, the real interesting thing is when you can make items change. Now the panel will look a bit snazzier and if you click the little chain link icon, you’ll visit your favorite website. Replace the one line that says Hello Hackaday with this:Įcho "Hello Hackaday | image='$ICON' href=" However, each line of text can have a pipe character and some attributes to spruce things up and add function. When you click, you’d see something like this: Excitement A bit snazzierĪs it is, this isn’t very exciting. If you put the Kargos widget on a panel and set it to read your script, you’ll wind up with just the text Hello Hackaday on your panel. In the simplest case, you’d have the script output a line of text that will appear on the panel, a separator, and then one or more lines of text that will appear when you click on the widget. For Kargos, you can set that interval in two different ways that we’ll talk about later. In general, the script will run periodically.

When you install the widget, you have to point it to a script. But you can expect to do some experimenting either way. Since I use KDE, I’m going to focus on Kargos, and I’ll point out a few things about Argos as I go. It isn’t clear if this is by design or some interaction with the KDE desktop which is always changing. Part of the problem, too, is the documentation is terse and you sometimes have things that work but not in every case. You really want to install from a clone of the GitHub, not from the release package or from the KDE repository for plasmoid. This is partly because the version in the KDE repositories is out of date and even if you grab the latest release off GitHub, it is still out of date with the documentation. To exacerbate that problem, the documentation for Kargos seems to be wrong.

Obviously, too, if you use a complied program that could pose a problem on the Mac unless you recompile. The bad news is that each has its own differences and quirks. The good news is that, in theory, you could write a script that would run under all three systems. If you use KDE (like I do) then you’ll want Kargos, which is more or less a port of Argos and adds a few things of its own. It is largely compatible with XBar, although there are a few things that it adds that are specific to it. That’s fine for the Mac, but what about Linux? If you use Gnome, there is a very similar project called Argos. The output printed from the program controls what appears on the widget using a simple markup-like language. You can write any kind of program you like - shell script, C, whatever. That program places a widget on your menu bar that can display anything you want. Turns out there is an easy answer and it was apparently inspired by, of all things, a tool from the Mac world. Most desktops support the notion of widgets, but developing them is a real pain, right? And even if you develop one for KDE, what about the people using Gnome? If you click on it, you get expanded status and can even issue some commands. You have a microcontroller that reads a number of items - temperatures, pressures, whatever - and you want to have a display for your Linux desktop that sits on the panel and shows you the status.
