OpenEXR - Python IntelliSense about openexr

[meshula]

Do you know why Intellisense can't autocomplete on OpenEXR? It sounds like a good thing to support if it doesn't require special maintenance. I don't know if anyone on the team has experience with Python and Intellisense.

My guess is that the file does not exist in *.py format.

For Imath it exists as Imath.py, but for OpenEXR it does not.

I created a simple python wrapper to solve this problem. I hope this project helps you in your decision making.

Although I haven't done much testing, I confirmed that it works well within the range I need (reading and writing files, extracting metadata, and intellisense support).

I don't know if this is the best way to support intellisense (there may be a way to expose it automatically).

However, I think OpenEXR is a very stable project.
And the number of interfaces exposed in the Python runtime environment is small.
Therefore, I think this method will also be easy to maintain.

Your solution does look easy to maintain, thanks for putting it together.

I'm not a Python expert, so please forgive my basic questions.

• Is this something we could incorporate into our project to solve the problem, or is it an example?
• will this benefit other systems, such as LSP, or environments like PyCharm?
• Is the problem solvable at the cpython level (or should we be investigating the problem at the c level?)

This is a project I created for my convenience, but since it's just a simple wrapper, I think it can be integrated into your project without any problems.

• will this benefit other systems, such as LSP, or environments like PyCharm?

As a result of the experiment, PyCharm reads the cython file and creates an OpenEXR.py file. (It automatically generates python code, just like automatically generating a document with code and comments.)
Therefore, in PyCharm, intellisense works for the methods in OpenEXR and I was able to read them.
But PyCharm failed to read the file completely.
I knew the name of each method, but I couldn't tell what the parameters were.
ex: It is written as InputFile(*args, **kwargs), so it is impossible to guess what the parameters are.

• Is the problem solvable at the cpython level (or should we be investigating the problem at the c level?)

In order for all IDEs to support this, it is assumed that the code must exist as *.py rather than solving it at the C or CPython level.

Thanks @404Vector !

@reinecke is there any guidance from the OpenTimelineIO project on this? I think OTIO went through a couple of iterations to get this working across the board.
