Application aware layer switching 🔁 with kanata ⌨️ and sway 💨

Additional features:

Current layer text overlay

• Using sdl2 for rendering just text, is overkill
• [ ] Find a more lightweight alternative
• Is there any better way of showing current-layer information?
• [ ] Maybe some sway prompt using ipc?

TODO 📔

• [ ] Configuration

  • [ ] List of registered apps that have specific layers
    • [x] Currently getting from file system (~/.config/keyboard/apps/*)
    • [ ] Get from config file?
  • [ ] Aliases and patterns for application names

• [ ] Refactor the code

• [ ] Don't rely on swaymsg, make universal

  • [x] Now using swayipc
  • [ ] Make it work on other than sway?

• [x] Whitelist/blacklist

• [ ] Make the overlay a compile time feature

• [ ] Fork kanata and apply the logging patches

How it works ⚙️

1. You have a main layer, this will be used by default.
2. You have a ~/.config/keyboard/apps/org.telegram.desktop layer. When telegram is focused it sends the window name (org.telegram.desktop in this case) to kanata. Kanata switches to this layer. NOTE: If it can't find the corresponding file in /apps it fallbacks to the default layer (main)

• Create a file and include it in your kanata configuration
  • NOTE: The name of the file should match what sway returns

Dependencies

• SDL2 for the overlay window, optional (todo)

How to run 🏃

git clone https://github.com/veyxov/qanata
cd qanata/
cargo run -- --port 7070

Visualize statistics generated from kanata

python script for generating heatmap for key presses

How to run:

./run_stats.sh --file path/to/kanata/log

# Current format: actual_key_presses|layer|resulting_key_press

Bugs 🐞

• [x] ~~Panics if there are no windows in current workspace (when the wallpaper is visible)~~
• [x] Overheats the CPU when sway is locked; Fixed in commit

Caution: This is very experimental and raw. Needs a lot of work to make usable
