Phoc sends output information *after* changing keyboard surface size. Squeekboard adjusts size on surface events, but not on output in this revision, making it unaware of display size at the time of adjustment, resulting in bad adjustment.
This change hardcodes the proportions again to make it work at least on the Librem5.
This commit is a bit bigger than it could have: Meson changes could have gone in separately from CI and Debian.
This commit looks more complicated than it should reasonably be. Alas, Cargo is a piece of work, and it doesn't let honest people just choose different versions of dependencies, leading to a cascade of misery. Several things were tried to curb the disaster:
- Cargo [feature] supports choosing dependencies, but doesn't support specifying dependency versions
- Cargo has a cfg() syntax in sections for choosing dependencies by build options, but it explicitly doesn't support selecting on features…
- Cargo allows choosing different dependencies based on features, so perhaps dependencies with different versions could live in stub crates pulled in as needed? Nope! If a dependency doesn't exist in the repo (and that's the point here), Cargo throws up its hands.
This means Cargo.toml needs to be generated based on the build type. More misery:
- we lose the simplicity of just doing `cargo.sh` for simple housekeeping like deps updates. HACKING.md was updated to reflect that. Perhaps that's inevitable - build options need to be like this.
- Some flaky adjustments needed in `cargo.sh` because of an additional argument that can be mistaken for an argument to the exec in `cargo run`.
- Specifying a custom `Cargo.toml` means Cargo can no longer find any tests, examples, benchmarks, or binaries, because it searches relative to the directory of `Cargo.toml`, which is now the build dir. Extra care needed to not forget about them now.
As soon as Cargo allows anything better for managing deps versions, the above should be undone in its favor.
Good side is that a couple bugs went away:
- build flags not always making it to Cargo
- arm64 builds were optional while they shouldn't
- test layouts in unit tests are loaded from an explicit directory now
The Bullseye versions of dependencies are canonical now, Buster considered legacy.
The manager is used for sizing the layer surface. It promises never to exceed half the output height.
The selection of the current layout is not being done here, leading to worse behaviour in 1:1 scaling.
In the future, it could be used for sizing the keyboard itself and the suggestion box, as well as decide which layout to use, because layouts should have some sizing hints.
Control and Alt are special in that they aren't expected to switch levels, and so don't need to change what characters are output.
Use in layouts by adding `modifier: Control` or `modifier: Alt` in place of `text: "foo"`.
The latching of the modifier will force the keyboard to emit raw key presses and prevent it from outputting text.
Erasing with zwp_text_input_v3 version 1 requires bytes, and bytes require get_surrounding_text. That, however, is optional. That's a mistake in protocol design.
Easiest to drop this until the mess is solved on the protocol side.
gio::Settings::set_value takes over ownership of the Variant sometimes, but in other cases it doesn't. To prevent this being a problem, the custom Variant is made of the type that will never have its ownership taken.
This is not necessarily consistent with what gtk-rs authors intended.
In practice, the ownership is shared by refcounting, and after the Rust reference is dropped, one taken by Settings survives.
Locking is not determined by button state any more, but rather based on the view active at the moment. If pressing/locking a key results in the current view being active, the key is active. If locking a key results in the current view, the unlock view is activated.
This ensures that the layout type information is accessible to the state manager when new layout information arrive.
The should be thought of as a stopgap measure. A proper solution would be to separate the state properly, and probably turn layout information coming from random places into messages that some object (thread?) collects and displays.
