Vyper for VS Code (alpha)

This extension brings the Vyper smart contract language for Ethereum to Visual Studio Code (a mix between editor and IDE). Like Vyper itself (and even more so) this extension is alpha software and should just be used to toy around with vyper. Compatibility with later versions cannot be guaranteed.

This extension is basically the result of hacking the Python highlighting support together with the ability to call command line tools from the Go extension and displaying the results of the StdError in a user-friendly way.

Features

• Provides the Vyper: Build Contract command that when called on a saved file shows the actual build errors.
• Syntax Higlighting for Vyper (*.vy, *.v.py) files inclusive Vyper specific types like int128.
• Build on Save
