Features
- Asynchronous plugin result loading
- No runtime settings (not a bug, but a feature)
- 5M memory on coldstart, 20M memory when all plugins are loaded
- Very quick startup (compared to some other graphical launchers
Configuration
All configuration at this moment is done by editing source files. This will be changed in the future to XMonad-style configuration.
Plugins
To configure the plugins, edit plugins :: [Plugin] in src/Main.hs. You should be able to just edit the list of plugins to disable the unneeded ones. All of plugins are enabled by default.
Triggers
Apply trigger to a plugin to make it the only plugin shown when query starts with a trigger, and apply triggerStrict to show a plugin only when it's triggered.
Window
Edit configuration top-level binding in src/Main.hs. The Configuration type constructor's field names should be self-explanatory.
Building
Nix
nix build should do everything for you.
Cabal
cabal new-run works for me. If it doesn't, add an issue!
