This reduces the impact of keyboard groups on the Keyboard.zig
implementation and otherwise improves consistency with patterns used
elsewhere in rivers code.
There are also two small changes to the riverctl interface:
- keyboard-group-add-keyboard is renamed to keyboard-group-add
- keyboard-group-remove is added to support removing keyboards from a
group.
This was removed a while back because it was buggy and I didn't know
of anyone using it. Since refactoring it is now trivial to implement
and I know of at least one person using it, so I don't mind reviving it.
e.g. `riverctl map -layout 0 normal Super Y spawn foot`
When this mapping is checked against a pressed key, layout 0 will be used to translate the pressed key instead of the currently active layout.
The number denotes to an index of the layouts set with
`XKB_DEFAULT_LAYOUT`.
Repeating mappings are created using the -repeat option to the map
command:
% riverctl map normal $mod+Mod1 K -repeat move up 10
- repeating is only supported for key press (not -release) mappings
- unlike -release, -repeat does not create distinct mappings: mapping a
key with -repeat will replace an existing bare mapping and vice-versa
Resolves#306
This code is complex and increases maintenance burden but doesn't
add any functionality, only eye-candy.
Futhermore, neither I nor any of the core contributors use it.
There may be a place in river for such eye-candy down the line, in which
case this code could be revived. Currently river is early enough in its
development that our focus should be on core functionality instead.
This protocol involves far too much accidental complexity. The original
motivating use-case was to provide a convenient way to send arbitrary
data to layout clients at runtime in order to avoid layout clients
needing to implement their own IPC and do this over a side-channel.
Instead of implementing a quite complex but still rigid options protocol
and storing this state in the compositor, instead we will simply add
events to the layout protocol to support this use case.
Consider the status quo event sequence:
1. send get_option_handle request (riverctl)
2. roundtrip waiting for first event (riverctl)
3. send set_foo_value request (riverctl)
4. receive set_foo_value request (river)
5. send foo_value event to all current handles (river)
6. receive foo_value event (rivertile)
7. send parameters_changed request (rivertile)
8. receive parameters_changed request (river)
9. send layout_demand (river)
And compare with the event sequence after the proposed change:
1. send set_foo_value request (riverctl)
2. receive set_foo_value request (river)
3. send set_foo_value event (river)
4. send layout_demand (river)
This requires *much* less back and forth between the server and clients
and is clearly much simpler.
Options are now all global but may be overridden per-output. If an
output local value is requested but none has been set, the global value
is provided instead. This makes for much better ergonomics when
configuring layout related options in particular.
