Hi Jaroslav, On Sun, Dec 01, 2019 at 05:04:50PM +0900, Takashi Sakamoto wrote:Since Audio Mini Conference 2018, I continued to work for alsa-gi[1] in my local to integrate toward better I/O libraries. However I realized that its basic design includes some disadvantages to produce useful APIs. I rethink the design and realize it better to wrap each of structures in <sound/asound.h> simply. Then, I restart it as alsa-gobject[2]. At present, master branch includes a library, `libalsactl0` for the most of I/O features in ALSA control interface, which is compatible with GObject mechanism and GObject introspection. Jaroslav, would you please delete the alsa-gi repository and fork the master branch from my alsa-gobject repository, then apply enough configurations to the new repository? My repository includes four branches as well for ALSA hwdep/rawmidi/timer/seq interfaces. The most of features in each interface is already available via included libraries but under heavy development. I already start to test them with Python 3 (PyGObject) and they seem work well. I also test them with Rust bindings generated by gtk-rs/gir[3] tool. Near future I also publish Rust crates for further convenience. For your interests, this Python 3 script is a sample to listen one event from ALSA control character device. This simple program is not terminated voluntarily or by sending UNIX signal, thus please generate control event by alsamixer or amixer: ``` #!/usr/bin/env python3 import gi gi.require_version('GLib', '2.0') gi.require_version('ALSACtl', '0.0') from gi.repository import GLib, ALSACtl class MyCard(ALSACtl.Card): def __init__(self, card_id, ctx, dispatcher): super().__init__() self.open(card_id) self.create_source().attach(ctx) self.__dispatcher = dispatcher def do_handle_disconnection(self): self.__dispatcher.quit() def do_handle_elem_event(self, elem_id, events): # Print the first event and quit event loop. print(elem_id.get_iface().value_nick, elem_id.get_device_id(), elem_id.get_subdevice_id(), elem_id.get_name(), elem_id.get_index(), events.value_nicks) self.__dispatcher.quit() ctx = GLib.MainContext.new() dispatcher = GLib.MainLoop.new(ctx, False) card = MyCard(0, ctx, dispatcher) dispatcher.run() ``` [1] https://github.com/alsa-project/alsa-gi [2] https://github.com/takaswie/alsa-gobject [3] https://github.com/gtk-rs/girWould I expect your arrangement for this project, or should I continue to develop it apart from alsa-project?
You're the only developer for this thus I'll shift the repos in the ALSA project on github. You should also write to README that this project is not using alsa-lib, thus the extra abstraction interfaces from alsa-lib cannot be used. Or do you plan to build gobjects on top of alsa-lib, too?
Thanks, Jaroslav
