Autocompletion in VScode editor for CoolProp

[Amir Aslanov]

Hello everyone, I have issues with autocompletion for CoolProp in Python

VScode refuses to provide suggestions in editor area, is it suppose to be like that? Completion works prefectly fine in jupyter interactive window

Does it have something to do with CoolProp being originally written in C++? I stumbled upon this issue on GitHub with similar problem in question

As I understood with little additional research on stub files in python — for autocompletion to work I must write/generate stub file with type annotations for CoolProp and use it for type checking. Is this the best approach? Are there better options?

Issue is demonstrated in the attached screenshots along with version information for python, CoolProp and VScode

Completion works for other packages :


No suggestions for CoolProp : 

Autocompletion works for jupyter interactive window :

Thanks for help

Yes, because they operate fundamentally differently. VS Code does not import and do introspection on imported things, rather they rely only on the presence of stubs. Jupyter under the hood does the import and figures out what is possible. Getting stubs to be generated properly is not a small endeavor and I think especially not straightforward for cython (upon which the Python interface of CoolProp is based).

Got it, thanks for reply, I think I'll try to fiddle with it for a while and share my findings if anything meaningful emerges out of it
