Plasma/Krunner/pt-br

KRunner (iniciado com Alt-F2 ou Alt-SPACE) é um iniciador integrado ao Plasma Desktop. Enquanto sua funcionalidade básica é iniciar programas de um tipo de mini-linha-de-comando, sua funcionalidade pode ser extendida por "runners" para ajudar o usuário completar suas tarefas.

Nota

Talvez você precise instalar pacotes de addons KRunner adicionais dependendo da sua distrubuição para usar algumas das funcionalidades listadas aqui. Note que um grande número de addons ativos possa deixar a ativação do KRunner mais lenta, ajuste isso clicando no ícone de "configurações" a esquerda da caixa de texto.

Funcionalidades

Essa lista tenta apresentar alguns exemplos básicos de como usar o KRunner. Descubra mais clicando no ícone '?' no KRunner.

Inicie e pare aplicações

Você pode iniciar programas apenas digitando o nome das aplicações que você quer iniciar - ou mais simples ainda: aperte a seta pra baixo para listar os programas mais usados recentemente que você digitou antes.

Você talvez digite um único caractere e KRunner vai começar a encontrar resultados. Resultados são encontrados das aplicações do seu menu de aplicativos customizável (para isso, botão direito no menu).

Examples:

Input	Output
gwe	(inicia Gwenview)

Você pode usar o KRunner para encerrar aplicações também. Digite a palavra-chave kill seguido pelo nome do processo e KRunner vai disponibilizar opções para fechar a aplicação (SIGTERM) ou sair forçadamente (SIGKILL). KRunner irá buscar por nomes de processo parciais nas aplicações rodando.

Note que a palavra-chave kill pode ser mudada no runner "Encerre Aplicações" para evitar confusão com o comando shell kill que aceita IDs de processos.

Instalação Direta

Caso você esteja procurando por uma aplicação ainda não instalada, KRunner irá sugerir uma lista de aplicações que correspondem com sua busca. como o KRunner foi integrado ao Plasma Software Center, Discover, apresentará uma lista de aplicativos, permitindo que você prossiga com a instalação direta.

Inicie comandos (shell)

Além de aplicações listadas no menu de aplicações, KRunner também pode ser usado para rodas comandos shell, isso inclui iniciar binários. Note que quando escrevendo comandos shell, KRunner não aceitará comandos parciais ou autocompletar automaticamente.

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).

Examplos:

Input	Output
ls ~/Documentos	lista os conteúdos de ~/Documentos (preferencialmente por um terminal)
cp ~/Documentos/meuArquivo ~/meuArquivo	copia meuArquivo de ~/Documentos para ~/
mplayer meuFilme.mkv	toca meuFilme.mkv no 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 # or man:/ to open the man page formatted for easy readability in your browser.

Examples:

Input	Output
#ls	opens the manual for ls in a browser
man:/grep	opens the manual for grep in a browser

Busque websites

Você pode simplesmente começar a digitar a URL de um website que você quer abrir no seu navegador padrão. Você talvez até digite o nome de um favorito e KRunner irá abri-lo para você. Se você já visitou o website antes, KRunner pode pegar resultados do histórico do seu navegador também.

Examplos:

Input	Output
meuFavorito	abre o favorito no navegador
kde.org	abre a homepage do KDE no navegador
http://userbase.kde.org/	abre Userbase no navegador

KRunner already knows your Web Shortcuts, found in Plasma System Settings, so you can directly start using them.

Examples:

Input	Output
gg:KDE	searches Google for KDE
wp:krunner	searches Wikipedia for krunner

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.

Abra arquivos, pastas e dispositivos

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 enabled "File Search" provided by Baloo daemon, 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

Multitarefa com seções, janelas, áreas de trabalho e atividades

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
new session	starts a new session

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.

Fale com pessoas

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

Escute alguma música

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

Sempre em ponto

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.

Calculadora

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 also supports combinatorics functions, like perm() or comb().

Examples:

Input	Output
= perm(10,5)	30240
= comb(10,5)	252

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 )	[3, -7]

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)

Viage

Se você tem lugares favoritos no Marble (no OpenStreetMap), KRunner pode abrir no mapa diretamente.

Correção de escrita e caracteres especiais

KRunner pode te dizer quando sua escrita está correta e/ou sugerir correções. A palavra-chave padrão para iniciar a correção ortográfica é spell e pode ser configurado.

Exemplos:

Input	Output
spell linux	Palavras sugeridas: Linux, lynx, ...

'KRunner também permite você escolher caracteres especiais se você especificar o unicode hexadecimal do caracter, precedido por um sinal #.

Exemplos:

Input	Output
#03b2	β
#00b1	±

Gerencie seu computador

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
restart	restarts computer
shutdown	shutdowns computer

Usage

Open KRunner

The easiest way to open KRunner is to trigger its global shortcut (Alt+Space or 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/Ctrl+j or Shift+Tab/Ctrl+k 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 '?' 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.
