Local use without a published extension

VS Code (manual install)

1. Copy to a local extensions folder:

   mkdir -p ~/.vscode/extensions/n6-local
   cp -r syntaxes ~/.vscode/extensions/n6-local/

2. Create ~/.vscode/extensions/n6-local/package.json:

   {
     "name": "n6-local",
     "version": "0.0.1",
     "engines": { "vscode": "^1.60.0" },
     "contributes": {
       "languages": [{ "id": "n6", "extensions": [".n6"] }],
       "grammars": [{
         "language": "n6",
         "scopeName": "source.n6",
         "path": "./syntaxes/n6.tmLanguage.json"
       }]
     }
   }

3. Restart VS Code → .n6 files highlight automatically.
