Nue for Visual Studio Code

Syntax highlighting and formatting support for the current Nue language.

Literally do not expect anything else from this extension at the moment.

Formatting

The extension looks for nue on the extension host's PATH unless nue.executablePath overrides it.

{
 "nue.executablePath": "/absolute/path/to/nue",
 "[nue]": {
  "editor.defaultFormatter": "NueLanguage.nue-vscode",
  "editor.formatOnSave": true
 }
}

For Remote SSH or containers, the executable must be available on that workspace's extension host.

Preview

Open this repository in VS Code and press F5 to launch Preview Nue highlighting. The development window opens the representative Nue source example.

Use Developer: Inspect Editor Tokens and Scopes to inspect the grammar scopes and the colours chosen by your current theme.

Check and package

Development checks use Node.js 22 or newer:

npm ci
npm test
npm run package

Packaging creates a vsix file, which can be installed with Extensions: Install from VSIX..., or:

code --install-extension ./nue-vscode-a.b.c.vsix

Optionally check tokenisation against a Nue compiler checkout:

NUE_SOURCE_ROOT=/path/to/nue npm test

This reads its examples and standard packages; it does not execute their code.

Set NUE_EXECUTABLE to enable the optional real compiler process check in npm test. For the full editor check, set it along with VSCODE_EXECUTABLE (the VS Code application executable) and run npm run test:editor.
