From 95cfe33fa50b0b5992ead1d471bc3483b15266b5 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sun, 12 Apr 2026 04:04:16 +0000 Subject: [PATCH 1/3] Package MicroQuickJS as a WASI 0.2 Component Implemented a complete WASI 0.2 WebAssembly Component wrapper for MicroQuickJS. This includes: - `microquickjs.wit`: WIT interface defining JS evaluation and value manipulation (including resource management). - `glue.c`: C glue layer bridging WIT to the MicroQuickJS C API, implementing singleton context, rooting/unrooting of values, and WASI compatibility stubs. - `Makefile.wasi`: Dedicated build system supporting both wasip1 (with reactor adapter) and wasip2 targets, with optional wasm-opt post-processing. - `.gitignore`: Updated to include build artifacts. - Property-based tests in `tests/property_tests.js`. The component provides a lightweight, predictable static memory footprint (4 MiB arena) and supports persistent global state across multiple eval calls.
