CodeWorld是一個教育性的，基于Web的編程環境。用Haskell中的一個變種開發。它包括：

• 一套基于Web的工具，讓學生輕松地創建自己的電腦繪圖，動畫和游戲。
• 電腦游戲一個簡單的數學模型，設計靈感來自gloss。
• 能夠讓學生運行和使用他們的作品就在Web瀏覽器中，使用GHCJS作為一個編譯器。

構建和部署

Building CodeWorld is, unfortunately, an involved process at the moment. Here are the approximate step by step instructions to get an example working:

1. Install GHC 7.8, since it's required for GHCJS.
2. Get a patched version of cabal (https://github.com/ghcjs/cabal) and then git checkout ghcjs to switch to the GHCJS branch, and finallycabal install both the Cabal and cabal-install packages.
3. Get GHCJS itself (https://github.com/ghcjs/ghcjs) and cabal install.
4. Run ghcjs-boot --dev.
5. Check out ghcjs-dom (https://github.com/ghcjs/ghcjs-dom) and install it with cabal install --ghcjs.
6. Check out ghcjs-canvas (https://github.com/ghcjs/ghcjs-canvas) and install it with cabal install --ghcjs.
7. Install the codeworld-base package from this project: cd codeworld-base && cabal install --ghcjs.
8. Build codeworld-server from this project: cd codeworld-server && cabal build
9. Get a Google API key, and store it in web/clientId.txt.
10. Run the server: cd codeworld-server && ./run.sh 8080.

You can now access the CodeWorld system at http://localhost:8080.
