Catala Model Tree (VS Code Extension)

A lightweight VS Code extension for exploring Catala catala-metadata declarations in a normal VS Code session.

It displays a tree of:

Normal Local Install

This extension can be built as a local .vsix and installed into your regular VS Code instance. Publishing to the Marketplace is not required.

Open tools/catala-model-tree-vscode.
Install dependencies:
```
npm install
```
Build the extension:
```
npm run package
```
Install the generated .vsix into your normal VS Code:
```
code --install-extension catala-model-tree-0.2.1.vsix
```
Or use VS Code → Extensions → ... → Install from VSIX...
In the Catala workspace where you want to use it, run Catala Model Tree: Open from the Command Palette.

Use the Rebuild button to re-parse files after model changes.

The package script uses a pinned local vsce dependency instead of npx, so packaging is reproducible once dependencies are installed.
The default package path uses --no-dependencies, which is appropriate here because the shipped extension runtime is the compiled out/ bundle plus static assets, not the development toolchain.
npm run package:full is available if you ever want to test the standard dependency-traversal path.

catalaModelTree.modelFiles: glob patterns (workspace relative) for Catala files to parse.
- Default: src/**/*.catala_en
catalaModelTree.includeScopes: include scope declarations (default true).
catalaModelTree.includeStructures: include structure declarations (default true).
catalaModelTree.includeEnums: include enumeration declarations (default true).
catalaModelTree.rootScopes: optional list of scope names to include. Empty = all.
catalaModelTree.theme: auto, dark, or light.

This parser is intentionally simple and relies on regexes. It is meant to be fast and easy to extend.
It only reads catala-metadata declarations (declaration enumeration/structure/scope).
