Wipple is an educational programming language designed by Wilson Gramer. With Wipple, you can make art and music, explore math and science, design video games, and more.

You write Wipple code in the Wipple Playground, an interactive, collaborative, online coding platform. The playground works on any device with no setup required. With 80 lessons and guides, there’s something for everyone.

Wipple code is natural to read and write, and the language is designed to grow with you. Under the hood, Wipple is a powerful functional programming language with an expressive type system, but when you're just getting started, these features work invisibly. When you make a mistake, Wipple provides helpful, customizable error messages that guide you toward the solution.

The Wipple project is split across several folders. The compiler is written in Rust (via WebAssembly), and the playground is written in React. The documentation is published using mdBook.

You can use these commands to build and test Wipple locally. Make sure you have task installed.

# Build and install the compiler and VSCode extension from source
task install

# Run tests
task test

# Serve the website at http://localhost:8080
# (you will need a '.env' file in 'web'; see '.env.example')
task web:serve

Once you have wipple in your PATH, you can run an example program with these commands:

cd example
echo 'show "Hello, world!"' > src/test.wipple
wipple run

You should see Hello, world! in the console.
