[Risolto] aiuto per applet javascript

Messaggioda shouldes » martedì 1 maggio 2012, 18:17

Avrei bisogno dell'auito di un programmatore che ci capisca di javascript.
Spiego un po' la situazione.
Ubuntu 12.04 LTS installata da netinstall.
Per la gestione dell'audio mi sono affidato a alsa+xfce4-volumed+volumeicon+xfce4-mixer.
Tutto funziona.
/etc/xdg/autostart:

Codice: Seleziona tutto
[Desktop Entry]
Type=Application
Exec=volumeicon
Hidden=false
NoDisplay=false
X-GNOME-Autostart-enabled=true
Name=volumeicon
Comment=
Icon=multimedia-volume-control


Codice: Seleziona tutto
[Desktop Entry]
Type=Application
Exec=xfce4-volumed
Hidden=false
NoDisplay=false
X-GNOME-Autostart-enabled=true
Name=xfce4-volumed
Comment=
Icon=xfce4-keyboard


org.gnome.settings-daemon.plugins.media-keys:
Volume down → disabilitato (ci pensa xfc4-volumed con tanto di notifica in tema %)
Volume up → disabilitato (ci pensa xfc4-volumed con tanto di notifica in tema %)
Volume mute → disabilitato (ci pensa xfc4-volumed con tanto di notifica in tema e simboletto)

configurazione di volume icon, che appare perfettamente nell'area di notifica di Cinnamon e si comporta come la vecchia applet volume di gnome (volendo si può anche configurarla proprio identica), prima di pulseaudio:
Codice: Seleziona tutto
[StatusIcon]
stepsize=1
lmb_slider=false
mmb_mute=false
onclick=xfce4-mixer
theme=White Gnome

[Hotkeys]
up_enabled=false
down_enabled=false
mute_enabled=false
up=XF86AudioRaiseVolume
down=XF86AudioLowerVolume
mute=XF86AudioMute

[Alsa]
card=hw:0


Ora sorge il problema, exaile... si vede quasi mai nell'area di notifica causa grave bug di cinnamon, rhythmbox... dopo che hanno deciso di rimuovere il plugin tray icon non spunta proprio, ho scaricato dei plugin da github per avere rhythmbox nell'area di notifica, stando attento che non mancassero pacchetti necessari, ma non funziona.

L'idea era di modificare la sound-applet, rimuovendo tutto quello che ha a che fare con pulseaudio, nella speranza che si avvii e funzioni perfettamente.
Io faccio da cavia, ma mi serve qualcuno che sia in grado di farlo.
Al momento non funziona affatto, quindi mi basterebbe anche un funzionamento parziale.

I file da modificare sono questi:
Codice: Seleziona tutto
{
 "uuid": "sound@cinnamon.org",
 "name": "Sound",
 "description": "Cinnamon sound applet",
 "icon": "stock_volume"
}

il primo è semplice, gli cambio nome e gli metto l'icona di rhythmbox.
Poi c'è questo per il quale mi serve assistenza:

Dovrei abolire tutto ciò che appartiene a pulseaudio e ai controlli di sistema (volume) e lasciare solo la funzione media-player, anche solo per rhythmbox va più che bene.

Al momento tramite tasto XF86AudioMedia rhythmbox ritorna (si ripristina la finestra) e tramite tasti XF86AudioPlay/Pause/Previous/Next riesco a controllarlo, ma mi pare di avere il sistema castrato.

Teoricamente è molto semplice, basterebbe snellire il file, ma non ho mai avuto a che fare con roba del genere.
Se vi servono chiarimenti su qualcosa, che non sia programmazione in javascript, sono a completa disposizione.
Intanto provo a farla io qualche modifica e se ci riesco vi aggiorno.

prima avevo molti più errori.
Non so se è normale, ma il primo avvio del player non posso farlo dall'applet, la prima volta devo avviare con il tastino o dal menù.

Re: aiuto per applet javascript

Messaggioda shouldes » mercoledì 2 maggio 2012, 0:02

Questa è la versione attuale, è perfettamente funzionante l'applet, ma andrebbe corretta.
Io mi sono limitato ad eliminare un sacco di roba immaginando la funziona che svolgesse.
Ora ci sono un bel po' di righe in meno e un bel po' di righe di errore nel log della sessione.
Vorrei eliminare questi errori dal log, anche se non ci sono problemi di funzionamento.
