Workbench

PyPI Python CI Documentation License

Workbench is a native Qt 6.8 technical-art application for editing Slang programs, inspecting compiler/reflection results, and seeing changes through QRhi without an export/relaunch loop.

Run Workbench

For a zero-install launch on Python 3.11–3.13:

uvx miskeyed-workbench

The equivalent command is pipx run miskeyed-workbench. For a persistent command, use pipx install miskeyed-workbench or uv tool install miskeyed-workbench.

Platform support

Platform Wheel Python Default backend CI runtime validation
Windows x64 ✅ Packaged 3.11–3.13 D3D11 ✅ D3D11 + Vulkan/SwiftShader on Py3.11
Linux x64 ✅ Packaged 3.11–3.13 Vulkan ✅ Vulkan/lavapipe on Py3.11
macOS arm64 ✅ Packaged 3.11–3.13 Metal ✅ Metal on Py3.11
macOS x86_64 ✅ Packaged 3.11–3.13 Metal ✅ Metal on Py3.11

Supported is the intended product contract. Packaged means a wheel is published. Tested means installed-package and native contracts run. Runtime validated means the named QRhi backend recorded a draw in the release matrix. See the detailed installation and platform support.

What Workbench is

It currently ships two contributions inside one document-centric shell:

  • Render Toy binds open documents to a Scene pass and a Post pass;
  • Shader Toy binds one document to a minimal fullscreen shader consumer.

Both share the workspace, editor, reflection-driven Inspector, deterministic time model, and native rendering services. ANARI host work remains opt-in research and is not a shipped UI mode.

Why Qt, Slang, and QRhi?

  • Slang supplies language semantics, modules, in-process compilation, reflection, entry points, and generated backend code.
  • Qt supplies the native application/widget lifecycle and Shiboken exposure.
  • QRhi supplies one native rendering seam across D3D11, Vulkan, and Metal.

C++ owns lifecycle, synchronization, command submission, resources, and Python exposure. There is no Python-owned renderer and no runtime slangc or qsb subprocess.

The distribution is miskeyed-workbench; the developer/library import is miskeyed.workbench. Wheels target CPython 3.11–3.13 on Windows x86_64, Linux x86_64, and macOS arm64/x86_64.

Platform and backend status

Auto selects D3D11 on Windows, Vulkan on Linux, and Metal on macOS; Windows may also request Vulkan with --rhi vulkan. The release matrix separately records whether each wheel built, installed in a fresh environment, passed installed-package contracts, and rendered through a QRhi backend. The active runtime backend is independent of the HLSL/GLSL/SPIR-V/Metal target selected in the Generated viewer.

Build from source

Requirements are CMake 3.24+, C++20, Qt/PySide/Shiboken 6.8.x, Slang, and Python 3.11–3.13. Set CMAKE_PREFIX_PATH to the Qt development SDK and SLANG_ROOT to the Slang SDK, then build without isolation:

python -m pip install --no-build-isolation -e . -v

The matching shiboken6-generator comes from Qt's package index rather than PyPI; the base dependencies alone are not enough for a source build.

Learn and contribute

Canonical screenshots and Sphinx HTML are generated deployment artifacts rather than repository inputs. On a built Windows checkout, reproduce the complete site with:

python -m pip install -r src/docs/requirements.txt
python -m ci.build_docs --output build/documentation/site

Pull requests upload the complete site as a read-only review artifact. Trusted same-repository PRs also publish that artifact to /dev/; fork PRs never publish. A release run publishes the immutable /0.3.0/ snapshot to the generated docs branch and updates the public root to redirect to that stable version.
