Overview

Clogs: Shoes, worn over libui.

Shoes is _why the lucky stiff's tiny Ruby GUI toolkit. Clogs implements the Shoes drawing and layout model on top of libui, a small cross-platform native widget library, so Shoes programs run on plain CRuby -- no browser engine, no JVM, one small native dependency.

The Shoes API itself comes from Lacci, the display-independent half of Scarpe. Clogs is a Lacci display service: Lacci owns the DSL and the drawable tree, Clogs owns the pixels. Run an app with:

SCARPE_DISPLAY_SERVICE=clogs ruby my_app.rb

or simply require "clogs" before Shoes.app.
