Wing Examples

This directory contains a collection of Wing examples of the kinds of apps you can build in Wing! Check out the Wing Contributor's Handbook for a guide on on how to add your own example.

The examples in the tests directory are examples specifically used for testing the compiler. tests/valid are examples that should compile successfully, and tests/invalid are examples that should fail.

The examples in proposed are examples that may not yet work in the current version of Wing, but we want to make them work in the future!
