KRunner est le lanceur construit sur le bureau Plasma. Bien que sa fonction de base est de lancer des programmes à partir d'une sorte de mini ligne de commande, ses fonctionnalités peuvent être enrichies à l'aide des « runners » pour permettre à l'utilisateur de réaliser un grand nombre de tâches.

Note
Vous pourriez avoir besoin d'installer des paquetages additionnels à KRunner suivant votre distribution pour utiliser certaines des fonctionnalités listées ici.


Fonctionnalités

Cette liste malheureusement incomplète tente de présente quelques exemples basiques de l'utilisation de KRunner. Découvrez-en davantage en cliquant sur l'icone '?' dans KRunner.

Démarrer et arrêter des applications

Vous pouvez lancer des programmes en tapant simplement le nom de l'application que vous voulez lancer. Vous devez taper au minimum trois caractères pour commencer la recherche. Les correspondances seront trouvées parmi les applications dans votre menu applications.

Exemples:

Entrée Sortie
gwe (démarre Gwenview)

Vous pouvez également utiliser KRunner pour tuer des applications. Saisissez le mot-clé tuer suivi du nom du processus and KRunner vous proposera le choix entre fermer l'application (SIGTERM) ou la forcer à quitter (SIGKILL). KRunner fera correspondre les noms partiels des processus (au moins trois caractères) parmi les processus qui tournent.

Notez que le mot-clé tuer peut être modifier dans le runner « Terminer des applications ».

Issue (shell) commands

In addition to applications listed in the applications menu, KRunner can also be used to run shell commands, including launching binaries. Note that when entering shell commands, KRunner will not accept partial commands or offer command auto completion.

Running a command like this brings up a wrench icon which offers additional options. You can choose to spawn a terminal and run the command there (this can be useful if your command produces text output that you want to read), or choose to run the program as a different user (by providing the username and password of that user).

Examples:

Input Output
ls ~/Documents lists contents of ~/Documents (preferably in a terminal)
cp ~/Documents/myFile ~/myFile copies myFile from ~/Documents to ~/
mplayer myMovie.mkv plays myMovie.mkv in mplayer

Incidentally, if the command line is your thing, you may appreciate the built in integration to man pages. Simply type a command name preceded by a # to open the man page formatted for easy readability in your browser.

Examples:

Input Output
#ls opens the manual for ls in a browser

Naviguer sur les sites web

Vous pouvez simplement saisir l'URL du site web pour l'ouvrir dans votre navigateur par défaut. Vous pouvez même saisir le nom d'un marque-page de [[Special:myLanguage/Konqueror|Konqueror] ] et KRunner l'ouvrira pour vous. Si vous avez visité le site web dans le passé, KRunner peut aussi aller vous chercher des résultats à partir de l'historique du navigateur.

Exemples:

Entrée Sortie
monSignet ouvre le signet dans un navigateur
kde.org ouvre la page d'accueil de KDE dans un navigateur
http://userbase.kde.org/ ouvre Userbase dans un navigateur

KRunnerconnait déjà vos raccourcis web dans Konqueror, donc vous pouvez directement démarrer en les utilisant.

Exemples:

Entrée Sortie
gg:KDE recherche « KDE » sur Google
wp:krunner recherche « krunner » sur Wikipédia

KRunner fournit également des options pour télécharger des fichiers depuis le web via KGet en fournissant leur URL.

Des runners supplémentaires existent pour rechercher sur Wikipédia, Wikivoyages et KDE Techbase.

Open files, folders and devices

KRunner can also open files and directories on your local machine for you. If you want to browse remote machines, you can do that, too. Notice how KRunner uses kioslaves for ssh (fish:) and samba (smb:).

Examples:

Input Output
file:/home/ opens file:///home/ (the Home directory) in Dolphin
file:myMovie.mkv opens /home/myMovie.mkv
fish:you@server.com opens fish:/you@server.com/ via fish (file over ssh) protocol
smb:myWindowsBox opens smb:/myWindowsBox via Samba

If you don't know the path to a file, simply type the name of the file. If the file is a recently opened document, KRunner will list it for you. If you have the Nepomuk subsystem installed, you can also search your computer for the file by its indexed contents. KRunner will also open folders you've bookmarked in Dolphin (in your Places sidebar) if you type their name in. What's more, if you want to access devices on your system (both mounted and unmounted), you can do that, too. KRunner will even provide device-specific options.

Examples:

Input Output
Home opens the Home directory in Dolphin
myFlashDrive shows options to mount or open the contents of myFlashDrive

Multitask with sessions, windows, desktops and activities

Several KDE applications allow you to save and load sessions. KRunner allows you to launch these sessions. You can either type in the name of the application or directly type in the name of the session. Runners exist for opening sessions saved in Kate, Konqueror, Konsole, etc.

KRunner is a multitasker's dream. If you have too many windows open, just type in the title of the window and switch directly to it. You can similarly type in the name of a virtual desktop and switch directly to it. If you roll with activities, switch activities by typing their name in. KRunner will find a match as soon as you type three characters in.

KRunner will even switch desktop sessions for you. Type in the keyword switch or new session to start a separate X session. You can switch back and forth between sessions by using the switch keyword.

Examples:

Input Output
Desktop 1 switches the virtual desktop to Desktop 1
myWorkActivity switches the activity to myWorkActivity
switch shows options to switch to an existing session or start a new one

Several plasma widgets can be launched as windowed applications. You can simply type the name of a widget and KRunner will launch a window for you.

Talk to people

Type in the name of a contact in your KAddressBook to get a list of options to contact them. Typing in an email address into KRunner will open a KMail composer window. You can also search through contacts in your Kopete contact list.

The addressbook and kopete runners don't seem to be working in SC 4.8.

Examples:

Input Output
kde@mail.kde.org compose a mail to the KDE mailing list
myContact show options to contact myContact

Listen to some music

You can control any modern audio player such as Amarok using krunner. You can use several keywords (all configurable) to play, pause or skip songs. Typing in the name of an artist, album or song that is in Amarok's library will let you either play immediately, play next (queue) or play at the end (append) of the current playlist. You can use keywords to increase or decrease the volume of the player, or even to mute or quit it.

Examples:

Input Output
play song search plays a song immediately
pause pauses Amarok or your designated music player
next plays next song in playlist

Soyez à l'heure

Vous pouvez connaitre la date et l'heure actuelle en tapant les mots-clés date ou time. Sélectionner le résultat le copiera dans votre presse-papier de manière à ce que vous puissiez le coller n'importe où. Le format de la date et de l'heure respecte vos réglages système.

Exemples:

Entrée Sortie
date La date d'aujourd'hui est ...
time L'heure actuelle est ...

Vous pouvez même connaitre la date et l'heure d'un autre endroit en indiquant le fuseau horaire ou la ville listée dans la base de données TZ.

Exemples:

Entrée Sortie
time UTC L'heure actuelle dans UTC est ...
time oslo L'heure actuelle dans Europe/Oslo est ...
time calcutta L'heure actuelle dans Asie/Calcutta est ...

There is a runner for interfacing with Korganizer and fetching events, but it doesn't seem to be working in SC 4.8.

Calculator

KRunner features a very versatile calculator that can be called by starting or ending a calculation with an = sign. In addition to basic arithmetic, you can call scientific functions like sqrt(), sin(), log(), etc. A list of the supported functions is here. Note that trigonometric functions like sin(), cos(), etc expect the angle in radians. KRunner understands pi in expressions.

Examples:

Input Output
32*12 = 384
= sqrt(4) + 32*sin(30*pi/180) 18

KRunner can also handle symbolic mathematics and perform integration and differentiation on expressions

Examples:

Input Output
= integrate( -x/y^2, y ) -x/y
diff( log(x) ) = 1/x

You can also use KRunner to solve polynomial functions to find its roots.

Examples:

Input Output
= solve( x^2 + 4*x - 21 = 0 ) [7, -3]

KRunner intelligently handles units as part of the calculations. Try the following examples to see how.

Examples:

Input Output
= 2.5 kg * 10 m/s^2 25 N
220 V / 10 A = 22 ohms

Since KRunner understands most units, you can use it to convert them very quickly. Note that unit conversions don't require an = sign.

Examples:

Input Output
30 F -1.11111 degrees C (°C), 273.039 K, ...
27.8 km 1.09449e+06 inches (in), 17.2742 miles (mi), ...
5 gallons in liters 18.9271 liters (l)

KRunner knows currencies, too. Conversions between currencies is done by fetching the exchange rate from the European Central Bank website.

Examples:

Input Output
1 dollar 0.657002 pounds sterling (GBP), 0.742501 euros (EUR), ...
125 euros 110.606 pounds sterling (GBP), 15,785 yen (JPY), ...
30 JPY in RUB 9.40731 rubles (RUB)

Go places

If you have bookmarked locations in the Marble (in OpenStreetMap), KRunner can open the map directly.

Spell checking and special characters

KRunner can tell you whether your spelling is correct and/or suggest corrections. The default keyword to start the spellchecker is spell and can be configured.

Examples:

Input Output
spell linux Suggested words: Linux, lynx, ...

KRunner can also allow you to pick special characters if you can specify the hexadecimal unicode for the character, preceded by a # sign.

Examples:

Input Output
#03b2 β
#00b1 ±

Manage your computer

You can directly open system settings control modules from KRunner. Often, if you want to change something, just type associated terms and KRunner will find the control module with the settings you want.

Examples:

Input Output
keyboard opens the Keyboard settings control module
fonts opens the fonts settings control module
password opens the Password & User account control module

KRunner can also be used to adjust the screen brightness by using the keywords "screen brightness". You can specify a percentage or just turn the brightness halfway or fully down. Additionally, keywords exist to suspend, logout, shutdown or restart your machine.

Examples:

Input Output
screen brightness 100 increases screen brightness to 100%
sleep suspends computer to RAM
lock locks the screen

Usage

Open KRunner

The easiest way to open KRunner is to trigger its global shortcut (Alt+F2, by default). In some activities (e.g. Desktop), you can simply click on the desktop and start typing. In others (e.g. Search and Launch), KRunner may be built into the activity itself.

You can also right-click on your plasma workspace and select Run Command... or just simply launch it from the commandline by typing krunner.

Use KRunner

Use Tab or Shift+Tab to navigate up and down results. Use arrow keys to move between options (if any) in a result. Use Enter (or left click) to select a result.

Discover KRunner

Click on the wrench icon to bring up configuration options where you can enable/disable/configure runners that will process your searches. Additional options are available to change the position on the screen where krunner appears. You can even change the style to a task-oriented interface, if you like.

Clicking on the waveform icon will open the System Monitor.

Clicking on the '?' icon opens a scrollable list that explains the syntax of all the available runners. This is a good way to discover new functionality!

Tips, Tricks and FAQs

You can use KRunner in a special "single runner" mode. While in this mode, krunner will only have one active runner to process your searches. This feature isn't supported by all runners, but quite a few already do. Open the global keyboard shortcuts control module directly from krunner and choose the "Run Command Interface" to see what's available. Set a global shortcut for the mode you want and launch krunner in that mode. You can have as many modes as you can find shortcuts for.
