Unable to associate file extensions with a bdist_msi

[kbasaran]

I have an application which is able to open files from command line. It uses argparse to get the file name.
https://github.com/kbasaran/Linecraft/blob/0.1.2/main.py

    parser.add_argument('infile', nargs="?", type=argparse.FileType('r'), action="store",
                        help="Path to a '*.lc' file. This will open a saved state.")

I try to associate the application to '*.lc' files in Windows, using a .msi installer.
https://github.com/kbasaran/Linecraft/blob/0.1.2/setup.py

bdist_msi_options = {
    "extensions": [{
                    "extension": "lc",
                    "verb": "load state",
                    "executable": "main.exe",
                    }]
                   }

Unfortunately, while the executable from the build still opens files passed to it in command line, double clicking on a '*.lc' file does not work. It doesn't even start the application. I look forward to your advice on this.

Please, check this sample: https://github.com/marcelotduarte/cx_Freeze/tree/main/samples/msi_extensions

The verb should be "open", "print", "view", ...

OK thank you. This way it does start the application.
Yet the filename doesn't seem to get passed to it as an argument. I added a debug line to print the 'args.infile' and it returns None.

In the sample cited, in the README,
4. optionally arguments, e.g. "%1" for proper quoting, but any other program arguments can be passed (see sample),

and in the setup.py has the use of argument, so in your case:
"argument": '"%1"',

[kbasaran]

Yes, the argument solved my problem. I had followed this sample and assumed argument was not necessary: https://github.com/marcelotduarte/cx_Freeze/blob/main/samples/msi_extensions/setup.py. But I should have tried it anyways. Thank you for your time.
