From 28273eb74074e74f3e94d2db822db092290bc64e Mon Sep 17 00:00:00 2001 From: giles Date: Tue, 31 Mar 2026 17:44:11 +0000 Subject: [PATCH] Fix component-source SSR override, add SX island tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit component-source from data/helpers.sx was overriding the native OCaml version. The SX version calls env-get with wrong arity (1 arg vs required 2), producing empty source. Re-bind the native version in SSR overrides after file loading. Note: source code still not visible because highlight function returns empty — separate issue in the aser rendering pipeline. Also adds: - spec/tests/test-reactive-islands.sx — 22 SX-native tests for all 14 reactive island demos (render + signal logic + DOM) - tests/node/run-sx-tests.js — Node runner for SX test files - tests/node/test-reactive-islands.js — 39 Node/happy-dom tests Co-Authored-By: Claude Opus 4.6 (1M context) --- hosts/ocaml/bin/sx_server.ml | 25 +++ spec/tests/test-reactive-islands.sx | 225 +++++++++++++++++++++++++++ tests/node/run-sx-tests.js | 83 ++++++++++ tests/node/test-reactive-islands.js | 229 ++++++++++++++++++++++++++++ 4 files changed, 562 insertions(+) create mode 100644 spec/tests/test-reactive-islands.sx create mode 100644 tests/node/run-sx-tests.js create mode 100644 tests/node/test-reactive-islands.js diff --git a/hosts/ocaml/bin/sx_server.ml b/hosts/ocaml/bin/sx_server.ml index 0e4eed5c..7cbec7d4 100644 --- a/hosts/ocaml/bin/sx_server.ml +++ b/hosts/ocaml/bin/sx_server.ml @@ -2140,6 +2140,31 @@ let http_mode port = let bind name fn = ignore (env_bind env name (NativeFn (name, fn))) in bind "effect" (fun _args -> Nil); bind "register-in-scope" (fun _args -> Nil); + (* Re-bind component-source — data/helpers.sx overrides the native version + with an SX version that calls env-get with wrong arity.
