Plug-ins for Compositing WMs
this text is solely about a idea for a project.
The KDE4 site [1] has given their reasoning on why to reject Compiz.
Expectedly Gnome will jump in similiar wording. I just want to raise one
point about compositing effects/plug-ins. Plug-ins form a great users
space to interact with ideas and code.
It is correct stated that Compiz exposes too much details about its
internals into plug-ins. So its hard to reuse compiz plug-in code for say
kwin.
Anyway the underlying logic is pretty simple.
Shaders are small text files.
The desktop has a visible and virtual size, workspaces, monitor outputs,
windows, subwindows, edges, a task bar, shortcuts, a property system
(Xorg Xatom's) and some more.
So from a logical point of view it could be possible to write one
plug-in for serveral compositing engines.
What I, as a plug-in author, would find great is a project, which
developes a common script language and implements native plug-ins for each
of those window managers acting as a script host.
Based on a simple and common logic script authors could write text only
plug-ins. Obviously shaders are very likely to be part of such a system or
possibly OpenCL if mature enough.
I know coming with code or a detailed proposal is nicer. But if someone
searches for a nice Summer of Code project, that might become one.
