problema di base
Sto cercando una soluzione per enumerare tutte le applicazioni installate su un (Mac) del sistema OS X, vale a dire tutte le applicazioni in bundle registrati LaunchServices.enumerare tutte le applicazioni installate sul OS X
approccio semplice che non ha funzionato
(Si prega di notare: lsregister possono essere trovati sotto /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister).
Attualmente sto usando l'output di lsregister -dump | grep -E '^.*[ \\t]*path:[ \\t]+(\/.*)$' | grep -Eo '\/.*', che ha qualche problema:
.appfasci con a capo (\n, valida su UNIX) non vengono gestiti correttamente (Questo problema sarebbe risolvibile da scrittura un parser appropriato)lsregisternon gestisce correttamente il nome file (ad esempio contenente RTL mark).lsregistersembra ignorare i file con il marchio RTL nel loro nome. Se lo si desidera, è possibile creare un file con RTL nel suo nome eseguendo il seguente comando.python -c 'import shutil; shutil.copytree(u"/Applications/TextEdit.app", u"/Applications/ThisIsAWeird\u202EApp.app")'Dopo aver fatto questo, sarà
lsregister -dump | grep ThisIsAWeirdnon rivelarlo. Ma quando si fa clic con il pulsante destro su un file di testo e si passa a "Apri con", i servizi di avvio e il Finder continueranno a supportare tale file.
Basta enumerare tutti i file in /Applications e altre directory non funziona perché LaunchServices è a conoscenza di pacchetti applicativi in cartelle arbitrarie e ho anche bisogno di queste applicazioni.
Altro approch che io non sono riuscito a lavorare
A quanto pare, c'è una funzione API privata chiamata _LSFindApplications che fa esattamente quello che devo fare, ma non riesco a farlo funzionare e non ha trovato alcuna documentazione non ufficiale su internet. (La prova esiste: nm /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/LaunchServices | grep __LSFindApplications$)
UPDATE: metodo system_profiler, inoltre, non sembra funzionare
Fino ad ora ho anche se il metodo system_profiler come suggerito da @Anoop funziona ma oggi ho scoperto che lsregister raccoglie ancora su più binari. Alcuni o mancanti su tutte le macchine, alcuni sembrano mancare solo in system_profiler quando hai montato un volume esterno con un'altra installazione di OS X. Ecco un elenco di cosa manca nell'output di system_profiler (ma è presente in lsregister) su uno dei miei macchine

So che questo è possibile perché RCDefaultApp lo fa ma non so come. – zneak
