architecture about goose HOT 2 OPEN

Started by the user on a tty or by the display manager

I don't know exactly what it does, but some wayland window managers work better when started like this:

dbus-run-session goose

We should investigate what does this allow...

from goose.

Server:

• A long-running, standalone piece, written in C
• Started by the user on a tty or by the display manager
• Retains the true state of all that pertains to window management (not sure if there exists any other kind of state -- maybe mouse cursor position, but even that may get taken up by the underlying wayland software)
• State can be modified and queried from the outside, almost everything, like: states of windows, frames, outputs; positioning and ordering methods; configurables; etc.
• All outside communication to be done through either dbus, sockets + json, or plumbing?

(Server) State of environment:

• Available inputs, outputs, and other system information

(Server) State of windows:

• Open windows (and their programs)
• Their size, position, focus, order
• Their grouping, tagging, marking

(Server) State of management:

• Stuff currently in play, in relation to the "m" part of "wm"
• What is visible; how windows are laid out; rules, mechanisms, tactics; etc.

(Server) State of configuration:

• User specified stuff, colors, rules, log level, paths, etc.

(Server) State of input mapping:

• Keys/mouse-buttons do what

(Server) History:

• List of past window management events
• For purposes of undo, redo

Main client:

• A user-modifiable script, written in Tcl, that can send messages to the server in order to perform queries or modifications on the fly
• A set of script words (a Tcl library, an API) is provided by the server that hides most of the details of the message protocol

Overview client:

• A window management configurer that is mostly redundant (with the main client), but additionally provides an overlaid graphical means of control
• Hopefully doable in Tk, but wondering how then to achieve neat visual effects

Miscellaneous clients:

• Bars, pagers, Tk widgets, etc. that likely will be in the purview of end users
