Adding to this list requires explicit user approval — same gate as the TypeScript exemptions above. | Path | Banned thing(s) used | Rationale | Unblock condition | |---|---|---|---| | `packages/affinescript-cli/mod.js` | `process.platform`/`process.arch`/`process.env`, `node:fs/promises`, `node:child_process`, `Bun.spawn`, `Bun.file`, `Bun.write` | The shim is the **compiler-distribution front door**. Its consumers — LSP installers, IDE extensions, CI scripts wiring AffineScript into a build pipeline — overwhelmingly live in Node and Bun ecosystems, not Deno. Forcing them to install Deno solely to fetch+verify+exec a binary defeats the shim's "ergonomic install" purpose. The branches are guarded by single-line runtime detection at module load; nothing else in the repo depends on this pattern. | None — this is the intended steady state. The shim's whole job is to be runtime-agnostic. | +| `editors/vscode/test/**/*.js` | `node:*`, Mocha, `@vscode/test-electron` (Electron-based VS Code download + launch) | The **in-editor smoke harness** for issue #139 — loads the compiled `out/extension.cjs` in a real VS Code extension host and asserts activation, command registration, `restartLsp` cycling, and `deactivate` teardown. The VS Code extension host is npm/Node-native; `@vscode/test-electron` (the official runner) downloads a real Electron VS Code and launches it under `xvfb-run`. No Deno equivalent exists, and the test cannot be expressed in any other runtime. Scope is strictly `editors/vscode/test/` — no production code uses Node. | None — this is the intended steady state, paralleling the `affine-vscode-publish.yml` workflow that already uses npm at publish time (#104). | Browsers and Cloudflare Workers are NOT supported and never will be (the shim's purpose — fetch, save to disk, exec a native binary — cannot be done in a sandboxed JS runtime). The JSR runtime-compatibility checkboxes for this package should be: Deno ✅, Bun ✅, Node ✅, Workers ❌, Browsers ❌. diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 06b1cfbd..82935278 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -85,3 +85,37 @@ jobs: - name: Lint with odoc run: opam exec -- dune build @doc continue-on-error: true + + vscode-smoke: + # In-editor end-to-end smoke test for the .affine VS Code extension + # (issue #139).
