Linking python script to add-on main code

Add-ons Development
#1

Hello. I would like to use api win32 for creating an hidden file on win os. It seems not possible using js / nodejs. With python, importing the api, it is possible (with SetFileAttributes routine and FILE_ATTRIBUTE_HIDDEN parameter).

So how can I link a python script to the main js code? Can you please give me some reference about this matter? I ve found nothing on the web.

You can use js-ctypes - https://github.com/Noitidart/ostypes/issues/1

And then you can use CreateFile and then OS.Constants.Win.FILE_ATTRIBUTE_HIDDEN -

It might be possible with OS.File.setPermissions I’ll check.

You should have 0 need for python. Here aresome docs on js-ctypes:

I don’t recall how, but I’m pretty sure you can use nsIFile. Although the new methods for file system is OS.File and nsIFile is getting deperecated in various scopes.

This is how you do it with OS.File:

OS.File.setPermissions(
        OS.Path.join(OS.Constants.Path.desktopDir, 'my hidden file.txt'),
          {
            winAttributes: {
                hidden: true
            }
        }
)
.then(x => console.log('success:', x), y => console.error('failure:', y));

This will set the file on the deskto named my hidden file.txt to be hidden. Here are the other winAttributes:
