Varvara's Bicycle Release

Bicycle is an interactive Uxntal playground.

Bicycle is a companion application to Left, designed to evaluate little Uxntal programs. Bicycle lets you vizualize source code next to its equivalent bytecode and the resulting Uxn state.

To launch Bicycle as a companion application, you need just pipe the left.rom instance of uxnemu to the one of bicycle.rom:

uxnemu left.rom | uxnemu bicycle.rom

Left can send both a selection of text to be evaluated, or the entire working tal file, by pressing ctrl+p. The result should be instantly displayed in the Bicycle window.

As an alternative, to experiment with Uxntal you can also use the web-based REPL.
