As far as I know, no. At least no Wayland developer provided any feedback on gnome-accessibility, gnu-accessibility or any other of the accessibility-related mailing lists I'm subscribed to. Anyway, we have Wayland in consideration. Some historic context: We had a brief thread about this on 2010. It started on gnome-accessibility-list: https://mail.gnome.org/archives/gnome-accessibility-list/2010-November/msg00054.html Although it also touched gnome-shell mailing lists. https://mail.gnome.org/archives/gnome-shell-list/2010-November/msg00040.html Due this conversation, we include Wayland as one of the things to talk about in the first ATK/AT-SPI2 hackfest, and we created a bug to track it: https://bugzilla.gnome.org/show_bug.cgi?id=649556 But the conclusions of the Hackfest didn't provide too much light: https://bugzilla.gnome.org/show_bug.cgi?id=649556#c1 So we know basic things, like that we want X/Wayland totally transparent to ATK, and that probably AT-SPI2 will need to take that into account, but we lack the details. Why we didn't do anything else here? Well, basically because we are already overwhelmed with other stuff. > > In particular, the accessibility infrastructure will need to be fully > supported on systems that run Wayland without an X server. Unfourtunately, that means that current GNOME accessibility infrastructure will not work on Wayland right now. > The latest Wayland > update that I've read mentions keyboard handling as one of the aspects of > Wayland development that is still in flux, hence there may be opportunities > for those who understand the requirements of AT-SPI 2, Orca etc. in this area > to > make their requirements known before the relevant APIs are set. One of the current problems big problems is related to key events. In a short, as XEvIE is dead, we can't track key events directly from X server, so we are doing a key snooping on the application, and forwarding it via DBUS. This is not really performant, can have some collateral effects, and is the only remaining thing that makes X not really transparent to ATK. Since we started to talk about that, I have asking about how this could be done on Wayland. As you mention that key handling is still in flux, I guess that it is a good moment to ask. > http://lwn.net/Articles/491509/ Thanks for the link, I will read it shortly. > > I know that it will remain possible to run X as a Wayland client, but, given > the current thinking of X and Wayland developers, the norm will be for desktop > environments to use Wayland directly without an X server. > Yes, you are right. It seems that Wayland is the future (not sure if middle or long term yet), so it is good to really think about it.
