## Summary of the Pull Request Updates the vendored Monaco Editor from 0.47.0 (Mar 2024) to 0.52.2 (Dec 2024). ## PR Checklist - [x] **Communication:** Discussed in #46692 review - [x] **Tests:** Headless-browser smoke tests pass (syntax highlighting, custom languages, context-menu hack, addAction registration) - [x] **Dev docs:** No doc changes needed (update process unchanged) ## Detailed Description ### What changed | Area | Detail | |------|--------| | `src/Monaco/monacoSRC/min/` | Replaced with `monaco-editor@0.52.2` from npm | | NLS layout | `editor.main.nls.*.js` / `simpleWorker.nls.*.js` removed upstream → `vs/nls.messages.*.js` added | | New language | `typespec` shipped upstream (+1 language, 100→101 total) | | `monacoSpecialLanguages.js` | Inline grammar snapshots (cpp/xml/razor/vb/ini/shell) refreshed from 0.52.2 shipped files | | `monaco_languages.json` | Regenerated; all PowerToys custom languages + extension mappings intact | ### Supply-chain verification - npm tarball SHA-512 verified against registry SRI: `sha512-GEQWEZmfkOGLdd3XK8ryrfWz3AIP8YymVXiPHEdewrUq7mh0qrKrfHLNCXcbB6sTnMLnOZ3ztSiKcciFUkIJwQ==` - Vendored tree hash-verified file-by-file (103 files, all match) ### Why 0.52.2 and not 0.55.1 (latest)? Monaco 0.53+ completely restructured the `min/` bundle: flat hashed chunks instead of per-language AMD modules, `vs/platform/actions/common/actions` removed, `vs/basic-languages/<id>/<id>` modules eliminated. PowerToys' `index.html` (context-menu stripping via MenuRegistry) and `monacoSpecialLanguages.js` (language cloning via AMD require) depend on these internals. **0.52.2 is the last release compatible without a glue-code rewrite.** The 0.55.x port is tracked separately. ## Validation Steps Performed - [x] Tarball SRI integrity verified against npm registry - [x] Vendored tree == tarball (SHA-256 per file, 103/103 match) - [x] `monacoSpecialLanguages.js` passes Node.js syntax check - [x] Headless smoke test (Edge via puppeteer-core): editor creates, tokenization paints (5+ classes), `addAction` entries register, `MenuRegistry` context-menu hack works - [x] Same smoke test passes identically on 0.47.0 baseline (no regressions) - [x] `monaco_languages.json`: 101 languages, all custom IDs present (reg, gitignore, srt, cppExt, xmlExt, txtExt, razorExt, vbExt, iniExt, shellExt) ## Related - Supersedes automation approach in #46692 (which has fatal bugs; will close separately) - 0.55.x port tracked as follow-up issue Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: b6bd2181-eff3-4f2a-b25e-dcd1065ead6a
