forked from 12to11/12to11
6c7801f0fd
* 12to11.c (XLMain): Initialize primary selections. Transfer between X and Wayland programs is still incomplete. * Imakefile (SRCS, OBJS): Add primary selection related objects and sources. (primary-selection-unstable-v1.h): (primary-selection-unstable-v1.c): New targets. * README: Update what is not supported. * compositor.h: New prototypes. * data_device.c (XLDataDeviceSendEnter): Handle resource allocation failures. * mime1.awk: Update generated code for changes in target entry structures. * seat.c (SetFocusSurface): Handle focus change for primary selections as well. (FindSurfaceUnder): Cut off fractional portion instead of rounding the given coordinates, so the correct surface is found when the cursor is moved just inside the rightmost pixel. * surface.c (XLSurfaceRunFrameCallbacks): Handle timestamp overflow. * xdata.c (struct _TargetMapping): Rename atom to atom_flag, and use it to store flags. (MappingAtom, MappingFlag, MappingIsNextDuplicate, MappingSetFlag) (MappingUnsetFlag, MappingIs): New macros. (struct _TargetMappingTable): New structure. (Duplicate): New definition. (direct_transfer): Update duplicate types. (mapping_table): New hash table. (HashMimeString, SetupMappingTable): New functions. (FindTranslationForMimeType, Receive): Use the target mapping table to look up targets instead. (CheckDuplicate): New function. (SendOffers): Call CheckDuplicates. (XLInitXData): Set up duplicate relationship between UTF8_STRING and is conversion entry, and the targets mapping table.

This is a tool for running Wayland applications on an X server,
|
|
preferably with a compositing manager running.
|
|
|
|
It is not yet complete. What is not yet implemented includes support
|
|
for the primary selection, touchscreens, input methods, device
|
|
switching in dmabuf feedback, and the viewporter protocol extension.
|
|
|
|
There are also problems with output reporting in subsurfaces.
|
|
|
|
It is not portable to systems other than recent versions of GNU/Linux
|
|
running the X.Org server 1.20 or later, and has not been tested on
|
|
window (and compositing) managers other than GNOME Shell.
|
|
|
|
It will not work very well unless the compositing manager supports the
|
|
EWMH frame synchronization protocol.
|
|
|
|
Building and running this tool requires the following X protocol
|
|
extensions:
|
|
|
|
Nonrectangular Window Shape Extension, version 1.1 or later
|
|
MIT Shared Memory Extension, version 1.2 or later
|
|
X Resize, Rotate and Reflect Extension, version 1.3 or later
|
|
(this will soon be 1.4, once support for multiple GPU
|
|
systems is fully implemented)
|
|
X Synchronization Extension, version 1.0 or later
|
|
X Rendering Extension, version 1.2 or later
|
|
X Input Extension, version 2.3 or later
|
|
Direct Rendering Interface 3, version 1.2 or later
|
|
X Fixes Extension, version 1 or later
|
|
|
|
In addition, it requires Xlib to be built with the XCB transport, and
|
|
the XCB bindings for MIT-SHM and DRI3 to be available.
|
|
|
|
The following Wayland protocols are implemented to a more-or-less
|
|
complete degree:
|
|
|
|
'wl_output', version: 2
|
|
'wl_compositor', version: 5
|
|
'wl_shm', version: 1
|
|
'xdg_wm_base', version: 5
|
|
'wl_subcompositor', version: 1
|
|
'wl_seat', version: 7
|
|
'wl_data_device_manager', version: 3
|
|
'zwp_linux_dmabuf_v1', version: 4
|
|
'zwp_primary_selection_device_manager_v1', version: 1
|
|
|
|
With the main caveat being that zwp_linux_dmabuf_v1 has no real
|
|
support for multiple-provider setups (help wanted).
|
|
|
|
Window decorations are also not supported, even though they fit in
|
|
nicely with X window management.
|
|
|
|
It would also be nice to have pinch gesture support.
|
|
|
|
This directory is organized as follows:
|
|
|
|
Imakefile - the top level Makefile template
|
|
libraries.def - files for libraries that don't provide Imakefiles
|
|
*.xml - Wayland protocol definition source
|
|
*.c, *.h - C source code
|
|
|
|
Building the source code is simple, provided that you have the
|
|
necessary libwayland-server library, wayland-scanner, pixman, XCB, and
|
|
X extension libraries installed:
|
|
|
|
xmkmf # to generate the Makefile
|
|
make # to build the binary
|
|
|
|
Running the binary should be simple as well:
|
|
|
|
./12to11
|
|
|
|
Wayland programs will then run as regular X windows.
