Datascript Language Support for VS Code

A Visual Studio Code extension that brings syntax highlighting, basic formatting, and editor-friendly defaults to the Datascript DSL.

Features

• TextMate grammar for Datascript keywords, Mongo DSL operators, comments, strings, numbers, and built-ins.
• Document formatter that normalizes indentation and block structure (Ctrl+Alt+F or Datascript: Format Document).
• Inline configuration setting (datascript.format.indentSize) to align formatter indentation with project style.

More language services (diagnostics, hover docs, completions) are planned.

Development

npm install
npm run watch

In another terminal launch VS Code in extension development mode, pointing to the extension folder:

code --extensionDevelopmentPath "path\to\datascript\vscode-extension"

Open a .ds file, trigger the formatter, and live edits will rebuild thanks to the watch task.

Building & Packaging

• npm run build – compile TypeScript into dist/.
• npm run package – create a .vsix distributable using @vscode/vsce.

To publish, ensure you have a Personal Access Token (VSCE_PAT) for the Marketplace, then run:

npx @vscode/vsce publish

Testing

Formal integration tests are not wired yet. Future work will reuse @vscode/test-electron to spin up a headless VS Code and validate formatting + grammar expectations.

Repository Integration

This folder lives inside the main Datascript repo. Remember to regenerate the docs (docs/) or runtime pieces in tandem when language changes affect syntax highlighting/formatting.
