Krunner is exactly like that lovely, lovely 80s futuristic Dystopian sci-fi movie with Arnold and Jesse, except that is different in every single way. Now, for those of you who’ve fiddled with KDE before, possibly on a roof, hihi, then Krunner is not a stranger. It’s a familiar and useful application available in the desktop framework set of default tools. Only now we have Plasma at our disposal, and we need to give it a fresh new try.

This is also a good opportunity to expose any problems and bugs that may exist, as Plasma is still being shaped and molded, developed and tweaked, improved and bettered. With some tough love from readers and reviewers, it will only get more successful. Today, we will play with Krunner, and see its awesome powers. Indeed, Plasma is becoming my favorite desktop, and this is another great opportunity to gloat and fanboyize.

Let the tour begin

So what do you do with this fine beast called Krunner? First, you invoke it. This is done by using a key combo, or from the system menu. But using Alt + Space sounds fancier. Then, you start doing pretty much anything you can think of.

The Sound of Music

You can play music from Krunner. Invoke programs, play songs by specifying their path, or even use special commands to control Amarok or other media players. This will probably appeal to power users more than an average person, but wait, we’re just getting started.

Shell commands

If you’re into geeky stuff, then there’s nothing as cool as shell commands. Indeed, Krunner can execute shell commands. This means you don’t need to invoke Konsole directly, and you can do whatever you want from a single, unified interface. For example, you can play all media files of a certain format. But then, you have dedicated commands for that.

Manage applications

Start a program, they say. Kill a program, they say. Both options are available. When it comes to killing processes, you can specify signals, and of course, you have the whole repertoire of shell commands at the tip of your fingers.

Web browsing

If you’re really lazy, and you don’t feel like starting a browser on your own, you can access web pages through Krunner. Eventually, you should see the page loaded in the default browser. This functionality does not work in Vivid beta, but it does work in the recently, freshly released Netrunner 15 Prometheus. Lovely jubbly.

And more …

Is this the whole list? Hardly. Krunner can also interact with the desktop, like switch between virtual desktops, start a new session, send emails, search through contacts in Kopete, check date and time in multiple timezones, access Marble bookmarks, change system settings, and still more.

Plugins

In general, most of the stuff should work. But some of it’s still not yet ready. For example, I was not able to do any fancy mathematical calculations, which should be included in any desktop assistance software. The basic stuff works. Indeed, compare this to Cortana. And with the right kind of API, I see no reason why powerful computational knowledge engines like Wolfram-Alpha might not be used.

For most other plugins, you have a fair degree of freedom in configuring the options to your liking. You can setup the magic word used for spell checking and thesaurus, or maybe use special commands to control the media player of choice. The default program is indeed Amarok, and you have a bunch of cool commands at your disposal.

For the spellchecker, you can also enable the module to autodetect languages, automatically check words written into the Krunner text field, ignore special words like the names of programs used by Plasma, and more. This is quite handy.

Not all is perfect …

I may have hinted just earlier that some of the stuff is broken. This is indeed the case. On KDE, Krunner currently has more features and options, and it’s also more configurable. This will have to be resolved by the time Plasma 5 becomes mainstream, because otherwise, Krunner will become neglected and unused, and that would be a shame.

So, improvements

So what can be done to make Krunner into a stellar product? I believe that additional online integration should be considered, similar to what Ubuntu tries to do with its Launcher and scopes. Of course, this needs to be voluntary, opt in and such. Privacy and alike.

The functionality also must be intelligent and non-intrusive. Just read my Windows 10 review, and all the Cortana/search examples to get a feeling of how you shouldn’t be doing this. The basic idea is brilliant, but it is muddied by a wrong attempt to wed the desktop with the cloud.

That does not mean we should shun the cloud, as a technology and concept. But there must be a very delicate way online searches and calculations are introduced to the desktop, without harming the flow and harmony of everyday use. But also imagine the possibilities. If someone is inclined to use Krunner for literally everything, then a shopping plugin would do most nicely. And the same goes for books, weather, travel, social networks and sharing, and more.

But you all know how slippery the slope of this benign and hopeful attempt really is. One moment, you try to help people, and the next, they curse you for invading on their private lives and for pushing useless stuff down their throats. The same could, and probably will happen, if and when Plasma goes live, so to speak. Again, the possibility should not be discarded. It must be considered. And since Plasma 5 seems to be the most sensible desktop around, then I believe its developers will have the right insight to make Krunner and online integration just as sensible and smart.

Krunner should also be used for updates, as well as software and games purchases. Krunner can really be useful for people that want to stream movies and music, and many other cool things. The question is, where do you stop, because it can soon outgrow the desktop itself, gain intelligence and self-awareness, and then we’re fighting machines.

To sum it up, I believe Plasma 5 devs should take a bold step forward and begin a careful experiment with how clever and intrusive Krunner can really be without destroying the spirit of the desktop or dumbing down the users. With some patient work, it might just be possible to derive the golden formula that makes this desktop environment the future of computing. It could combine everything. Convenience, financial gain, ease of use, privacy. And that would make it the killer app of the Linux world. Once and for all.

Conclusion

Krunner is a hidden gem of the KDE and Plasma framework. True, all of what you see here has been around for many years. However, with the birth of Plasma 5, this little assistants gets a new meaning and importance, and it has the potential to revolutionize Linux.

It can be what it is, a program that indexes stuff, does some intelligent calculations, suggests a few useful things, and allows you to control your desktop and programs. Or it could be much more. With extra plugins, and some careful online focus, Krunner could become the most useful piece of the Plasma framework. Best yet, it can learn from the mistakes implemented in Unity, and then work around them. Given the sensibility I’ve witnessed in Plasma so far, there’s a good chance this could happen in a way that exceeds similar attempts, be it Linux, Windows or anything else. How about that? Anyhow, you have a new toy, so start playing. My fanboy rant is done for today.
