+
+In-browser playground for Ruff. Available [https://ruff.pages.dev/](https://ruff.pages.dev/).
+
+## Getting started
+
+- To build the WASM module, run `wasm-pack build --target web --out-dir playground/src/pkg` from the
+  root directory.
+- Install TypeScript dependencies with: `npm install`.
+- Start the development server with: `npm run dev`.
+
+## Implementation
+
+Design based on [Tailwind Play](https://play.tailwindcss.com/). Themed with [`ayu`](https://github.com/dempfi/ayu).

Martin Fischer	e9ec2a7b36	Add `use test_case::test_case;` to CONTRIBUTING.md I previously tried adding the #[test_case()] attribute macro and got confused because the Rust compilation suddenly failed with: error[E0658]: use of unstable library feature 'custom_test_frameworks': custom test frameworks are an unstable feature which is a quite confusing error message. The solution is to just add `use test_case::test_case;`, so this commit adds that line to the example in CONTRIBUTING.md to spare others this source of confusion.	2022-12-30 07:13:48 -05:00
