λauncher

λauncher is a GTK launcher application built with Haskell and gtk-gi-declarative.

Screenshots

Search for "hello world" on duckduckgo

All results for "firefox" (command launcher, calculator, window switcher)

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!
