dcode is LangChain's terminal AI coding agent, published to PyPI as deepagents-code. Pin the full langchain/langgraph dependency closure as resource blocks so brew install works offline and reproducibly.
The sdist requires compiling a WASM guest module against a proprietary WASI SDK tarball fetched from GitHub at build time, which isn't something a Homebrew resource build should attempt. Upstream already ships a portable py3-none-any wheel with the WASM blob embedded, invoked through the wasmtime dependency at runtime.
wasmtime's sdist build script downloads a prebuilt C-API tarball from GitHub releases at build time rather than compiling from source, which defeats the point of pinning a resource. Use the platform-specific wheels PyPI already publishes instead.
Pillow (a transitive dependency via the media extra) requires jpeg and zlib headers to build from source, plus freetype for font rendering support; mirror the same set the aider-chat formula uses.
Drops the full-URL workaround now that the tap lives in a homebrew-<name>-prefixed repo, enabling the short `brew tap` form.
Removes the rust/jpeg-turbo/freetype build dependencies by pinning each resource to its prebuilt wheel (per-platform where a package ships native extensions) instead of building from source, matching how pip/uv normally install these packages. Pins cryptography to 48.0.1 since 49.0.0 dropped macOS Intel wheels. forbiddenfruit has no published wheel but is pure Python, so it still builds instantly with no extra dependency. Validated end-to-end: a fresh Python 3.12 venv installing all 132 pinned resources plus the main wheel passes `pip check` clean and `dcode --version` runs correctly.
Runs `brew install --build-from-source` + `brew test` on all four platform combinations the formula's resource blocks target: macOS arm64/Intel and Linux arm64/x64.
Avoids the Intel macOS "larger runner" tier for this check; the arm64 macOS runner plus both Linux architectures still cover the formula's non-macOS-Intel resource branches.
The workflow needs to live on main to be picked up properly (e.g. workflow_dispatch only appears once a workflow exists on the default branch), which isn't merged yet. Moving it to its own branch/PR.
