🛠 Developer Guide

Running Quality Tests

The project includes a dedicated test suite for verifying linter logic and type inference.

cd pine-script-extension/server
npm run build
node out/test/test_runner.js

Note: New test cases should be added to pine-script-extension/server/test/cases.json.

Updating Built-in Metadata

To update function signatures or return types in the linter:

1. Edit pine-script-extension/server/scripts/update_core_params.js.
2. Run the script:

   cd pine-script-extension/server/scripts
   node update_core_params.js

Regenerating the Parser (Tree-Sitter)

If you modify the grammar:

cd tree-sitter-pinescript
npx tree-sitter build --wasm
cp tree-sitter-pinescript.wasm ../pine-script-extension/server/wasm/
