IronPython Stubs

Stubs for common IronPython CLR assemblies. These stubs are intended to be used by the autocomplete engine of editors like Atom, Sublime, and Visual Studio Code.

Why IronPython Stubs?

If your are writing python code that targets IronPython, and using modules loaded through the Common Language Runtime (clr), your editor's autocomplete engine (which runs on regular python) will not be able to access those non-native modules. In other words, modules/or packages loaded through clr.AddReference() are not available on your autocomplete engine.

The workaround here is simple: Use IronPython to crawl through these libraries, and create 'stubs' or 'mock objects'. These 'stubs' can then be used by the CPython autocomplete engine. The stubs include doc strings as well as constructor/function/method signatures.

This repository contains the code to create these stubs, and also stores an a version of them that can be used by autocomplete-python.




The wiki has step-by-step instructions for setting up your stubs for Atom, Sublime, Vim, Visual Studio Code.

Generate Stubs - Examples

ipy -m ironstubs make RhinoCommon ipy -m ironstubs make --all ipy -m ironstubs make DSCoreNodes --folder="DSCore" --directory="C:/Program Files/Dynamo/Dynamo Core/1.3"

Process Stubs


Known Issues

  • Performance is not great for some of the larger classes. If you know how this can be improved please let me know.
  • Some of the function/constructor signatures are missing or incorrect. This is a problem with Generator3. Please send a PR or let me know if you have a fix.
  • Overloaded Methods do not show correct arguments


This project is a fork of the repository started by Gary Edwards on Gitlab. Thank you for your work Gary - and thank you Ehsan for pointing me to it.

It uses PyCharm's Generator3 to create the stubs.
