Superkaramba

Introduzione

Come precedentemente indicato:

[Articolo e-zine]

[Superkaramba] è, in termini semplici, uno strumento che ti permette di creare facilmente eye-candy interattivi sul tuo desktop KDE. Attualmente, solo su linux è ufficialmente supportato.

SuperKaramba è uno strumento basato su karamba che permette a chiunque di creare e gestire facilmente piccoli widget interattivi su un desktop KDE. I widget sono definiti in un semplice file di testo che può essere aumentato con codice Python per renderli interattivi. Qui sono solo alcuni esempi di ciò che si può fare:

   * Mostra le informazioni di sistema come CPU, la riproduzione di MP3, ecc
   * Crea barre degli strumenti personalizzate che lavorano in ogni modo immaginabile.
   * Creazione di piccoli giochi virtuali o animali che vivono sul tuo desktop.
   * Mostra le informazioni da Internet, come il meteo e headlines.

Questo pacchetto è parte di KDE, come una componente del modulo KDE utilità.

Come consigliato nel sito ufficiale, per poter scaricare nuovi temi dovete andare a cercarli su kde-look.org, qui potrete trovare di tutto, dalle GUI per visualizzare le risorse alle dock-bar.

Installare Superkaramba

KDE3

# apt-get install superkaramba

KDE4

# apt-get install plasma-scriptengine-superkaramba

Utilizzo

Eseguire il comando

$ superkaramba

La finstra che si aprirà vi mostrerà diverse opzioni, tra queste vi è la possibilità di scaricare diversi oggetti da Kde.look, oppure aprire un tema scaricato o avviare un tema già caricato in superkaramaba ma non attivo.

Karamba003.jpeg

Consiglio di disabilitare la tray icon di superkaramba che reputo inutile.

Con un click del pulsante destro all'interno di un plasmoide di superkaramba si aprirà il menu delle opzioni

Karamba001.jpeg

da qui sarà possibile accedere al menù di superkaramba

Modifiche al tema

Con molta probabiltà alcune cose non funzioneranno a dovere al primo avvio di un tema.

Il fatto è dovuto alla non corretta configurazione dei parametri, infatti questi non vengono riconosciuti in automatico e sono legati a quanto scritto e testato dell'editore del tema.

I problemi più comuni sono legati alla scheda di rete (eth0 al posto di eth1 o altro), oppure al riconoscimento degli HD e delle partizioni montate che non hanno la stessa ubicazione e/o nome diverso(hda,sda,....), in questo caso occorre editare il file .theme.

Usate l'editor di testo che preferite e applicate le modifiche dovute, al salvataggio del file il tema si aggiornerà automaticamente.

Dipendenze importanti

Per poter visualizzare correttamente gli output karamba necessita di alcuni software a cui si appoggia.

Ecco un breve elenco degli indispensabili:

  • hddtemp
  • smartmoontol
  • sensors

Per le temperature delle GPU pare che solo i driver propietari di ATI e NVidia diano risultati.

bar

Displays a bar, like a progress bar, at the desired position. The bar is drawn using the image supplied by the path option. Images with transparency can be used. If the w and h options are not defined, the size of the bar equals the image size. By default, the bar goes from left to right, but a vertical (down-up) behavior is possible with the vertical option.

h - The height of the bar [optional].

path - The path to the bar image (relative to the config file, absolute location on the filesystem, or a http address).

vertical - If true, the bar gets vertical: bottom-up. default: vertical=false

value - The value of the bar. default: value=0

Tips

Warning.png ATTENZIONE

La funzione interval, che spesso se non indicata specificatamente impone tempi molto brevi di default nella sincronizzazione dei dati.

Su alcuni dati di scarsa utilità usare dei tempi lunghi, sempre espressi in millisecondi in modo da risparmiare risorse.



Il consumo della CPU nell'esecuzione di superkaramba dipende molto da questi tempi, si consiglia perciò di dilatare i tempi di esecuzione di ciò che si ritiene poco utile, come ad esempio il priprio IP locale che difficilmente cambierà, ha un tempo di default di 2500.

Per il resto seguite le vostre esigenze, sapendo ora che più breve sarà il tempo di aggiornamento del sensore, maggiore sarà il consumo di CPU.

Miscellaneous

clickarea

Defines a clickable area. Click in the area and the specified proram is executed. A double click is required if the window is not locked. The clickarea is used as a meter, i.e., sensors can be connected.

x - Horizontal position of the area's upper left corner.

y - Vertical position of the area's upper left corner.

w - The width of the clickarea.

h - The height of the clickarea.

preview - If preview=true, a rectangle will shown around the area.

onclick - The program that will be run when the area is clicked.

%v will be replaced with a possible sensor value.

Example:

clickarea x=0 y=0 w=100 h=10 onclick="kdialog --msgbox 'CPU load: %v'" sensor=cpu

defaultfont

The purpose of the defaultfont is to reduce the amount of parameters when using the text tag. Text labels after a defaultfont tag, in the theme file, will use the default parameters if the label has unspecified parameters.

The default is ignored if the text label has its own values. You don't need to specify all font parameters. Multiple defaultfont tags are allowed. Any previous defaults will be deleted.

Example:

defaultfont shadow=2 color=255,0,0
text x=0 y=0 value="test"
defaultfont font="times" fontsize=10 color=255,0,0
text x=0 y=40 value="test" font="arial"
text x=0 y=80 value="test" color=0,0,0

<group>, </group>

Items can be grouped together with the group tag. This will make it easier to move several items and at the same time keep the distances to each other. It is possible to have groups in groups.

x - Horizontal position of the group's upper left corner.

y - Vertical position of the group's upper left corner.

Example:

<group> x=20 y=20
text x=0 y=0 value="test1"
text x=10 y=10 value="test2"
</group> x=20 y=20

theme

Themes can be loaded from inside a theme using the theme tag. It is possible to create a theme that only loads other themes.

path - The path to the desired theme file.

example: theme path=noatun.theme
