Noir Language Support for Visual Studio Code

Visual Studio Code extension for working with the Noir programming language.

Features

This extension helps developers write, understand, and improve Noir code by providing:

• Syntax highlighting
• Compile errors and warnings on file save
• Run tests via codelens above each test
• Useful snippets for common code patterns

Requirements

For Language Server Protocol support, we require nargo v0.7.1+ to be in your PATH. You can check this by running nargo --version in your terminal and you can check for the lsp command by running nargo --help.

If you can't put nargo in your PATH, you can set an absolute path in the Nargo Path setting.

Settings

• Noir: Enable LSP (noir.enableLSP) - If checked, the extension will launch the Language Server via nargo lsp and communicate with it.
• Noir: Nargo Flags (noir.nargoFlags) - Additional flags may be specified if you require them to be added when the extension calls nargo lsp.
• Noir: Nargo Path (noir.nargoPath) - An absolute path to a Nargo binary with the lsp command. This may be useful if Nargo is not within the PATH of your editor.
• Noir > Trace: Server (noir.trace.server) - Setting this to "messages" or "verbose" will log LSP messages between the Client and Server. Useful for debugging.

Working on project

The project provides a few useful commands via npm scripts:

• npm run package - Builds the project and packages it into a .vsix file which can be manually installed for testing.
• npm run esbuild - Builds the project with esbuild to output out/extension.js and out/extension.js.map.
• npm run test-compile - Check types with TypeScript. Useful since esbuild doesn't typecheck.
• npm run format - Formats all the code in the repository.
• npm run check-format - Checks the formatting in the repository.
