diligent-drsn-packager 0.1.0

Prebuilt Diligent Engine RenderStatePackager CLI, distributed as a per-platform binary wheel

Diligent RenderStatePackager

Prebuilt Diligent Engine RenderStatePackager command-line tool, distributed as a per-platform Python binary wheel on PyPI. It compiles declarative render states (.drsn + HLSL) into a DeviceObjectArchive at build time, so an application can unpack pipeline states at runtime through IDearchiver instead of compiling shaders on startup.

The wheel ships only the native executable — install it and run the tool, with no need to build the packager (and all of DiligentCore + Dawn) from source.

Platform	Wheel tag	Serialized backends
Windows x64	win_amd64	Direct3D11, Direct3D12, Vulkan, WebGPU
macOS arm64	macosx_11_0_arm64	Vulkan, WebGPU
Linux x64	manylinux_2_28_x86_64	Vulkan, WebGPU

Installation

pip install diligent-drsn-packager
diligent-drsn-packager --help

The wheel is independent of the Python ABI (py3-none-<platform>) and works with any Python 3.8+.

Cloning the Repository

To build from source, clone with submodules:

git clone --recursive https://github.com/MikhailGorobets/Diligent-RenderStatePackager.git

If you cloned without --recursive, run git submodule update --init --recursive.

Repository Structure

Path	Description
CMakeLists.txt	Builds only the Diligent-RenderStatePackager executable
src/diligent_drsn_packager/	Python wrapper: get_executable_path() and a CLI passthrough
pyproject.toml, setup.py	Packaging into a platform-tagged binary wheel
bootstrap.sh	Init submodules, build, stage the binary
.github/workflows/	CI — build wheels (build.yml), publish to PyPI (publish.yml)
DiligentCore, DiligentTools	Pinned submodules

Build and Run Instructions

Requires CMake 3.19+, Ninja and a C++20 toolchain. On Linux also install X11/xcb development headers (a configure-time dependency of DiligentTools' NativeApp): apt install libx11-dev libxcb1-dev or dnf install libX11-devel libxcb-devel.

./bootstrap.sh            # init submodules, build, stage the binary
python -m build --wheel   # produce dist/*.whl
pip install dist/*.whl

Usage from CMake

Resolve the executable from the installed wheel at configure time:

find_package(Python3 COMPONENTS Interpreter REQUIRED)
set(_pfx "${CMAKE_BINARY_DIR}/_drsn_packager")
execute_process(COMMAND "${Python3_EXECUTABLE}" -m pip install --target "${_pfx}"
                "diligent-drsn-packager==0.1.0")
execute_process(
    COMMAND "${Python3_EXECUTABLE}" -c
            "import sys;sys.path.insert(0,r'${_pfx}');import diligent_drsn_packager as p;print(p.get_executable_path())"
    OUTPUT_VARIABLE PACKAGER_EXE OUTPUT_STRIP_TRAILING_WHITESPACE)
# e.g. ${PACKAGER_EXE} -o RenderStates.bin --vulkan --webgpu -s Shaders -r RenderStates -i Lib.drsn

Version Compatibility

A DeviceObjectArchive is bound to DiligentCore's serialization format (header ArchiveVersion); an archive only loads in a runtime built from a compatible DiligentCore commit. The wheel records the commit it was built from in diligent_drsn_packager.__diligentcore_sha__. When the submodules are bumped, release a new wheel version and pin to it in the consumer.

Release

Set the version in pyproject.toml, then tag:

git tag v0.1.0 && git push --tags

publish.yml builds every platform wheel and uploads them to PyPI via Trusted Publishing (OIDC). Configure the PyPI project's trusted publisher (this repository, environment pypi) beforehand.
