Nola for VS Code

Language support for Nola — a TypeScript superset (.tsi) where a configured LLM resolves ask ..`prompt` extractors at run time.

Features

• Syntax highlighting for .tsi: infer / ask keywords, extractor templates, ask with <provider> routing.
• Diagnostics — Nola parse errors and TypeScript errors, reported at the original .tsi positions.
• Hover, completion, go-to-definition inside .tsi files.
• Plain TypeScript interop — .ts files that import .tsi modules get full types; go-to-definition from .ts lands on the original infer function (via a bundled tsserver plugin).
• Debugging — the "Nola: Launch File" configuration snippet runs a .tsi entry under the Nola loader; breakpoints bind in .tsi source, stepping into an infer function works, and debug hover evaluates ..-contextual parameters.

Getting started

The extension expects a project using the nola-lang toolchain:

npm create nola-lang@latest my-app

The scaffold's editor step writes .vscode/launch.json (the debug configuration) and recommends this extension. In an existing project, run npx nola init and pick VS Code at the editor step.

For the language server and tsserver plugin to see your types, keep .tsi files inside a directory-style tsconfig include (the scaffold's ["src"] already does).

Debugging

Add the Nola: Launch File snippet from "Add Configuration…" in launch.json, or use the one the scaffold wrote. It runs node --import nola-lang/register with source maps wired so breakpoints and stepping stay in .tsi source.
