Wayland Protocols 1.46 Released With New Experimental Additions

([Wayland] 5 Minutes Ago Wayland Protocols 1.46)


Wayland Protocols 1.46 released this evening with new experimental protocols for text improvements as well as refinements to the color management protocol for HDR.

Wayland Protocols 1.46 brigns a new appendix and clarifications for the color-management-v1 protocol. A missing protocol error for color-representation-v1 is also added.

The experimental additions are for expanding on the existing text-input and input-method protocols. This experimental text-input protocol is text-input-unstable-v3. Dorota Czaplejewicz started it based on the existing text-input protocol with a goal of improving this protocol. Dorota is being funded by NLNet support.

Similarly, the new xx-input-method-v2 protocol is being worked on by Dorota and so far includes a new popup interface based on XDG-Popup. The existing popup interface of input-method (stable) was deemed "limited and inadequate for actual use."

Besides the refinements to the color management protocol and the new experimental work happening, Wayland Protocols 1.46 is a fairly small release. Details for those interested via the [1]mailing list announcement .

=== ALL USERS PLEASE NOTE ========================

CAR and CDR now return extra values.

The function CAR now returns two values. Since it has to go to the trouble
to figure out if the object is carcdr-able anyway, we figured you might as
well get both halves at once. For example, the following code shows how to
destructure a cons (SOME-CONS) into its two slots (THE-CAR and THE-CDR):

(MULTIPLE-VALUE-BIND (THE-CAR THE-CDR) (CAR SOME-CONS) ...)

For symmetry with CAR, CDR returns a second value which is the CAR of the
object. In a related change, the functions MAKE-ARRAY and CONS have been
fixed so they don't allocate any storage except on the stack. This should
hopefully help people who don't like using the garbage collector because
it cold boots the machine so often.
