storycad

Python wrapper around the StoryCAD .NET API (StoryCADLib.Services.API.StoryCADApi). Hosts the CLR in-process via pythonnet and exposes a Pythonic, snake_case surface; errors surface as StoryCADError instead of OperationResult<T> sentinels, and async (Task<T>) methods are joined inline.

The wheel bundles a published build of StoryCADLib under storycad/runtime/, so end users do not need the .NET SDK — only the .NET 10 runtime (the wheel is built with --self-contained false).

Prerequisites

• Python 3.10+
• .NET 10 runtime installed on the host (https://dotnet.microsoft.com/download)
• A supported platform (pip picks the matching wheel automatically): Linux x64, Linux arm64, macOS arm64, Windows x64.

Install

pip install StoryCADLib

Quick example

from storycad import StoryCAD

sc = StoryCAD()
guids = sc.create_empty_outline("My Story", "Author", "0")
overview = next(e for e in sc.get_all_elements() if e.element_type == "StoryOverview")
hero = sc.add_element(sc.item_type.Character, overview.uuid, "Hero")
sc.write_outline("/tmp/my_story.stbx")

Building from source

git clone https://github.com/storybuilder-org/StoryCAD
cd StoryCAD/bindings/python
./build-wheel.sh   # runs dotnet publish, stages runtime, then python -m build

The script detects your host RID, publishes StoryCADLib for the matching framework-dependent target, and produces a platform wheel under dist/.

Known limitations

• Async methods are joined synchronously on the calling thread — no real asyncio integration yet.
• Wheels are platform-specific; you need a wheel built for your OS + arch.
• StoryCAD is GPL-3.0-or-later. Bundling its DLL into a wheel inherits that license; any project that ships this wheel must comply.
