+## Cursor Cloud specific instructions
+
+**Demo server**: Start with `npm start` (port 3000). The demo server uses node-pty to spawn real shell sessions over WebSocket. Integration tests auto-start it via Playwright's `webServer` config, so you don't need to start it manually for `npm run test-integration`.
+
+**Build before testing**: Always run `npm run build && npm run esbuild` before `npm run test-unit`. Integration tests also need `npm run esbuild-demo-client` and `npm run esbuild-demo-server`. The update script handles this automatically on session start.
+
+**No external services**: This project has zero external dependencies (no databases, Docker, or APIs). Everything runs locally with Node.js.
+
+**TypeScript compiler**: The project uses `tsgo` (native TypeScript compiler preview) rather than standard `tsc`. It's installed via the `@typescript/native-preview` package.
+
+**Lint only changed files**: Prefer `npm run lint-changes` over `npm run lint` when iterating on code changes — it's significantly faster.

  A constructor setting, thus you would have to anticipate, whether (multiple) terminals in your page gonna do lots of concurrent decoding. Since this is normally not the case and the memory usage is only temporarily peaking, a rather high value should work even with multiple terminals in one page.
 - `storageLimit`  
  A constructor and a runtime setting. In conjunction with `storageUsage` you can do runtime checks and adjust the limit to your needs. If you have to lower the limit below the current usage, images will be removed in FIFO order and may turn into a placeholder in the terminal's scrollback (if `showPlaceholder` is set). When adjusting keep in mind to leave enough room for memory peaking for decoding.
- `sixelSizeLimit`  
-  A constructor setting. This has only a small impact on peaking memory during decoding. It is meant to avoid processing of overly big or broken SIXEL sequences at an earlier phase, thus may stop the decoder from entering its memory intensive task for potentially invalid data.

Daniel Imms	ddf2b7d091	Merge pull request #5969 from Tyriar/import-no-cycle-5897-2 Add oxlint import/no-cycle and break existing src/common cycles	2026-05-31 15:13:58 -07:00
Daniel ImmsandCursor	5684f95c8e	Colocate circular list types in CircularList.ts The import/no-cycle refactor had moved IInsertEvent, IDeleteEvent, and ICircularList into Types.ts, with CircularList.ts re-exporting the event types from there. That split the list abstraction from its implementation and pulled Types into the circular-list dependency graph. Define IInsertEvent, IDeleteEvent, and ICircularList in CircularList.ts alongside the CircularList class. CircularList.ts now depends only on Lifecycle and Event, not Types.ts. Remove those definitions from Types.ts (and the unused Emitter import). Update callers to import list types from CircularList: - buffer/Types.ts (IBuffer.lines) - DecorationService.ts (buffer line insert/delete handlers) - browser TestUtils.test.ts (mock buffer lines) Types.ts no longer imports or re-exports circular-list types, preserving the acyclic Types -> buffer/CircularList boundary. Co-authored-by: Cursor <cursoragent@cursor.com>	2026-05-31 14:37:01 -07:00
Daniel ImmsandCursor	cd3dcc52b2	Colocate buffer types in buffer/Types.ts The import/no-cycle refactor had moved IBuffer, IBufferSet, and related cell/line types into src/common/Types.ts, with buffer/Types.ts only re-exporting them. That inverted the natural module boundary and made buffer code depend on the top-level types hub. Define buffer-owned types in buffer/Types.ts instead: - CharData, IExtendedAttrs, IAttributeData, ICellData, IBufferLine - IMarker, IBuffer, IBufferSet, BufferIndex Restore UnderlineStyle to buffer/Constants.ts (used by IExtendedAttrs) and remove those definitions from Types.ts. buffer/Types.ts imports only what it needs from outside the buffer layer: ICircularList and ICharset from Types, IDisposable from Lifecycle, IEvent from Event, and UnderlineStyle from Constants. Types.ts does not import buffer/Types.ts, so the previous Types <-> buffer cycle stays broken. Update imports across common, browser, headless, addons, and tests to use common/buffer/Types for buffer types rather than common/Types.

Daniel ImmsandCursor	56a7195487	Add oxlint import/no-cycle and break existing src/common cycles Enable oxlint's import/no-cycle rule (import plugin) so circular module dependencies are caught in CI, similar to eslint-plugin-import/no-cycle and biome no-import-cycles discussed in the issue. Relocate shared types and dependencies to remove cycles under src/common: - Types.ts: host IInsertEvent, IDeleteEvent, IParams, UnderlineStyle, IBuffer, and IBufferSet; drop imports from CircularList, buffer/Types, parser/Types, and Services - CoreTerminal.ts: define and export ICoreTerminal - ServiceRegistry.ts: define IServiceIdentifier (break Services registry loop) - UnicodeService: stop constructing UnicodeV6; CoreTerminal registers the default v6 provider after service creation - buffer/Types.ts and parser/Types.ts: re-export moved types for callers Fixes https://github.com/xtermjs/xterm.js/issues/5897 Co-authored-by: Cursor <cursoragent@cursor.com>	2026-05-31 10:08:04 -07:00

Daniel ImmsandCursor	59d1ec7bf0	Migrate linting from ESLint to Oxlint (Fixes #5690 ) Replace the primary lint pipeline with oxlint and oxlint-tsgolint for type-aware TypeScript rules, preserving existing rule behavior from eslint.config.mjs via @oxlint/migrate and targeted jsPlugins (@stylistic/eslint-plugin, eslint-plugin-jsdoc as jsdoc-js, oxlint-plugin-eslint for no-restricted-syntax and object-curly-spacing). Keep a hybrid ESLint pass (eslint.config.naming.mjs) only for @typescript-eslint/naming-convention until tsgolint implements it (oxc-project/tsgolint#186). Legacy eslint.config.mjs and eslint.config.typings.mjs remain for reference but are no longer used by npm scripts. Add .oxlintrc.json for src/addons/demo/test and .oxlintrc.typings.json for typings/ (syntax-only, no --type-aware). Update lint, lint-fix, lint-api, and lint-changes to run oxlint first, then naming ESLint. Platform binaries install via oxlint-tsgolint optionalDependencies on Linux, macOS, and Windows.

Daniel ImmsandCursor	5d8da19c44	Keep path mappings for addons after core migration Follow-up to https://github.com/xtermjs/xterm.js/issues/5896 / PR #5966. Converting addons to ../../../src/common relative imports broke unit tests: esbuild emits addon code under addons//out-esbuild/ without mirroring the shared tree, so Node could not load TypeScript sources at runtime (Cannot find module '../../../src/common/Lifecycle'). Core src/, test/, and headless continue to use relative imports with no common/ path mappings. Addons keep the prior model until build layout can share out-esbuild the same way as the main package. Changes: - Restore common/* and browser/* paths in addon src/test/benchmark tsconfigs - Revert addon imports to common/ and browser/ path-mapped specifiers - Restore NODE_PATH=out-esbuild in bin/test_unit.js for Mocha resolution - Restore webpack resolve.alias on addons that bundle against out/ Fixes CI test-unit failures on remove-path-mappings-5896.

Daniel ImmsandCursor	17ad33dc3d	Remove TypeScript path mappings in favor of relative imports Fixes https://github.com/xtermjs/xterm.js/issues/5896 TypeScript path mappings for common/, browser/, and headless/* were not rewritten in emitted JavaScript, which forced webpack resolve aliases and NODE_PATH workarounds so runtime could resolve modules. That added build complexity and broke tooling such as ESLint import/no-cycle. Changes: - Convert ~750 imports across src/, addons/, and test/ to relative paths - Remove common/browser/headless paths and src catch-all mappings from tsconfigs (keep @xterm/addon-* demo and addon typings paths) - Remove webpack resolve.alias for common, browser, headless, and vs - Drop NODE_PATH from unit tests, benchmarks, and VS Code launch config - Fix addon-image IIPImageStorage to import ./Types after removing catch-all * Verified: npm run build, esbuild, package, package-headless Co-authored-by: Cursor <cursoragent@cursor.com>	2026-05-31 09:16:10 -07:00
