W.I.P. Hot key daemon for X.Org
License: GNU General Public License v3.0
Hotkeys are stored in a tree. The tree (currently) looks like this:
#[derive(Clone)]
pub enum KeyTree {
// A and B after each other separately
// On interpretation: A should be true
// On interpretation again: B should be true
Sequence(Box<KeyTree>, Box<KeyTree>),
// A and B should be true at the same time
All(Box<KeyTree>, Box<KeyTree>),
// A or B should be true at a time (not exclusive)
Any(Box<KeyTree>, Box<KeyTree>),
// the key should be pressed by the user
Single { key: xcb::Keysym, replay: bool },
}
The problem: The user presses keys and the app should match the keys with the current KeyTree (subject to change).
The idea is to create a state machine, that has the KeyTree and its current state. It should be owned by the Binding
(binding.rs) struct or the Binding
(binding.rs) struct could be the machine itself. The machine will get every xcb::Keysym
(the key), and it should return None
or Some(usize)
, where the usize
will be the order number of the matched item in an Any
subtree.
For e.g: super + {c, s}
if let Some(i) = state_machine.process_key() {
match i {
1 => run_chromium(),
2 => run_slack(),
}
}
