Add type stubs

[tooruu]

Please consider adding type stubs. Without static type information, it feels like walking in total darkness: no auto-completion, no types, no parameters, nor return values—nothing. It is very easy to introduce bugs, and you just can't predict what will happen in the code.

I made my own stubs based on PythonScript docs and Scintilla docs, but due to the lack of details and my zero prior experience with stubs, especially for code that interfaces with C++, I'm afraid they can't be fully correct without some help.

Let me know if you are interested in adding my type stubs to the project. I can open a pull request with the necessary changes for you to review.

Afaik boost::python offers no possibility to create the pyi files automatically from the C++ sources. Another problem could be how to use PythonScript and where to place the resulting Npp.pyi file. Currently I create my stubs file by querying the Npp object itself.

@chcg
I'm not sure, but can we have a workflow action which starts Npp and the file would be created via the startup.py?

I place Npp.pyi in the Scripts directory of the plugin, where all script files reside. This way the IDE picks it up automatically during development.

but if you use e.g. a local Python installation and pyls, then the search path knows nothing about PythonScript directories.

Which IDE?
The IDE I'd like to see do this (auto-completion, types, parameters, return values) is N++ itself. :-)

Which IDE?

PyCharm/VSC. IMO Notepad++ serves another purpose, and it's not worth making an IDE out of it.

[Ekopalypse]

Now I'm confused, PythonScript is a Notepad++ plugin and its only purpose is to be used with Notepad++. So... why would someone use VSC, for example, to write a script to be used with Notepad++?

I do my PythonScripting development with N++; PS dev doesn't really have power IDE features (e.g. debug), but it could more easily have the stuff being discussed in this issue. There are some other efforts underway, e.g. LSP...

@Ekopalypse What is necessary to create such a pyi file? I think it is sufficient to create it together with my local runs of https://github.com/bruderstein/PythonScript/blob/master/PythonScript/src/CreateWrapper.py when syncs from N++ are done.

@chcg - thank you for your continued commitment to the PythonScript project.

To create the stubs file, I use this script.

Without your recent changes, this would create an incorrect file.

Also, if you look at the code, you'll notice that NppReMatch is ignored because it looks like it's not being used by any Npp method.

Let me know if there is anything else I can help you with.
