\u00c8 stata presentata la biblioteca GUI Cosmoe, che supporta l'esecuzione su Linux in ambienti basati su Wayland. Cosmoe consente di creare programmi con interfaccia grafica in linguaggio C++, utilizzando API in stile library class del sistema operativo BeOS per la creazione dell'interfaccia. La biblioteca offre la possibilit\u00e0 di eseguire direttamente su Linux programmi che utilizzano le API di BeOS. Il codice del progetto \u00e8 distribuito con licenza MIT. <\/p>\n

Cosmoe offre un set di classi C++ che consentono di creare interfacce utente in modo facile e veloce. Da un lato, Cosmoe \u00e8 sostanzialmente pi\u00f9 semplice e compatto rispetto a toolkit come GTK e Qt, ma dall'altro consente di creare interfacce con un aspetto pi\u00f9 moderno rispetto a leggeri come FLTK e Xforms. Su sistemi obsoleti, Cosmoe permette di ottenere un consumo di risorse molto ridotto, mentre su quelli moderni consente di spremere la massima prestazione dall'hardware grazie all'uso intenso del multithreading. \u00c8 fornita una collezione di esempi di applicazioni che utilizzano Cosmoe per la creazione di interfacce, tra cui un emulatore di terminale, un editor di stili e semplici giochi. <\/p>\n

La biblioteca \u00e8 basata su una versione leggera e senza necessit\u00e0 di componenti server (app_server, registrar) derivata dal codice sorgente del progetto Cosmoe Classic, convertito per funzionare su compositori server<\/a>, utilizzando il protocollo Wayland. Il progetto Cosmoe Classic ha lavorato per portare l'ambiente Haiku OS per funzionare sopra il kernel Linux e ha utilizzato il rendering dell'interfaccia in una finestra creata con la libreria SDL. Lo sviluppo di Cosmoe Classic \u00e8 stato ripreso l'anno scorso dopo un'interruzione di diciassette anni. <\/p>\n

Attualmente, il progetto \u00e8 stato riorientato dallo sviluppo di un fork del sistema operativo Haiku verso la creazione di una biblioteca separata per la realizzazione di applicazioni grafiche per Linux. A questo stadio, lo sviluppo \u00e8 in fase alpha, con la biblioteca che gi\u00e0 supporta circa il 95% di tutte le funzionalit\u00e0 delle API di BeOS. Tra le limitazioni pi\u00f9 importanti, si segnala l'assenza di supporto per istanze di tipo BBitmap non legate allo schermo, necessarie per l'accelerazione hardware del rendering, e la mancanza di prontezza dell'API BFilePanel, che genera dialoghi per l'apertura e il salvataggio di file.
