Plasma/Krunner

KRunner, Plasma masaüstü için yapılmış bir başlatıcıdır. Küçük komut satırı benzeri bu alanın temel işlevi, programları çalıştırmak olsa da, kullanıcının birçok görevi tamamlamasında yardımcı olacak "çalıştırıcılar" ile geliştirilebilir.

Özellikler

Bu tamamlanmamış liste, KRunner kullanımının bazı temel örneklerini sunmaya çalışıyor. Daha fazlasını KRunner içerisindeki '?' simgesine basarak keşfedebilirsiniz.

Uygulamaları başlat ve durdur

Uygulamaları, basitçe isimlerini yazarak çalıştırabilirsiniz. Eşleşmeleri aramaya başlayabilmek için en az üç karakter girmelisiniz. Eşleştirmeler, uygulamalar menünüzdeki uygulamalardan bulunacaktır.

Örnekler:

Giriş	Çıkış
gwe	(Gwenview) çalıştır

KRunnerı, uygulamaları sonlandırmak için de kullanabilirsiniz. kill ve ardından sürecin adını yazdığınızda KRunner, uygulamayı kapatmak (SIGTERM) veya zorunlu çıkmak (SIGKILL) için seçeneklerinizi görüntüleyecektir. KRunner (en az üç karakter girildiğinde) çalışan uygulamalar arasında kısmi eşleme yapacaktır.

kill anahtar sözcüğünün, "Uygulamaları Sonlandır" olarak değiştirilebileceğini unutmayın. Bu, süreç No'su alan kill kabuk komutu ile çakışmayı önlemek içindir.

(Kabuk) komutlarını çalıştır

Uygulamalar menüsünde listelenen uygulamalara ek olarak, KRunner ikilileri çalıştırmak da dahil olmak üzere kabuk komutlarını çalıştırmada kullanılabilir. Bir komut girerken, KRunnerın kısmi komutlar kabul etmeyeceğini veya otomatik tamamlama önermeyeceğini unutmayın.

Buna benzer bir komut çalıştırmak, ek seçenekleri görüntüleyen bir ingiliz anahtarı görüntüleyecektir. Bir uçbirim oluşturup komutu orada çalıştırabilir (eğer komutunuz metin çıktısı görüntülüyor ve okumak istiyorsanız kullanışlı olabilir) veya programı farklı bir kullanıcı olarak çalıştırabilirsiniz (kullanıcının adını ve parolasını yazarak).

Örnekler:

Giriş	Çıkış
ls ~/Belgeler	~/Belgeler içeriklerini listeler (tercihen uçbirimde)
cp ~/Belgeler/dosyam ~/dosyam	dosyam dosyasını ~/Belgeler dizininden ~/ dizinine kopyalar
mplayer filmim.mkv	mplayer içerisinde filmim.mkv'yi oynatır

Bu arada, eğer komut satırı sizin için ise, man sayfalarına bütünleştirmeyi takdir edebilirsiniz. Sadece komutun önüne # yazın ve kolay okunabilirlik için biçimlendirilmiş man sayfasını tarayıcınızda açın.

Örnekler:

Giriş	Çıkış
#ls	ls için kılavuzu tarayıcıda açar

Web sitelerinde gezin

Bir web sitesini öntanımlı tarayıcınızda açmak için sadece adresini yazmanız yeterli. Hatta Konqueror içerisindeki yer imi adını bile yazabilir ve KRunner'ın sizin için açmasını sağlayabilirsiniz. Eğer bu siteyi geçmişte ziyaret etmişseniz, KRunner, tarayıcınızın geçmişinden de sonuçları getirebilir.

Örnekler:

Gİriş	Çıkış
yerİmim	yer iminizi tarayıcınızda açar
kde.org	KDE ana sayfasını tarayıcınızda açar
http://userbase.kde.org/	tarayıcınızda KullanıcıEvi sayfasını açar

KRunner Konqueror web kısayollarınızı zaten biliyor. Doğrudan kullanmaya başlayabilirsiniz.

Örnekler:

Giriş	Çıkış
gg:KDE	Google'da KDE araması yapar
wp:krunner	Vİkipedi'de krunner araması yapar

KRunner also provides options to download files from the web using KGet by providing their URL.

Additional runners exist for fast searching on Wikipedia, Wikitravel and KDE Techbase.

Dosya, klasör ve aygıtları açın

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

Oturum, pencere, masaüstü ve etkinliklerle çoklu görevler

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

Be on time

You can get the current date or time by typing in the keywords date or time. Selecting the result will copy it to your clipboard so you can paste it elsewhere. The format of the date and time respects your system settings.

Examples:

Input	Output
date	Today's date is ...
time	The current time is ...

You can even get the date and time at another location by specifying the time zone or the city listed in the TZ database.

Examples:

Input	Output
time UTC	The current time in UTC is ...
time oslo	The current time in Europe/Oslo is ...
time kolkata	The current time in Asia/Kolkata is ...

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.
