Exception in the `startup.py` tries to open a random command line file
- PythonScript: 3.0.20.0
I have an extension to the Notepad++.
In the extension I have using the startup.py to parse an extra command line looking like this:
notepad++.exe -nosession -multiInst -z --custom_parameter_1 -z "<path-to-custom-file-list>" -z --custom_parameter_2 -z custom_parameter_3
The startup.py has a code:
...
with open(path_to_custom_file_list, 'rb') as file_list:
...
...
Which throws the exception:
FileNotFoundError: [Errno 2] No such file or directory: "<path-to-custom-file-list>"
This is ok, as long the file does not exist.
But, then Notepad++ tries to create a new file with the dialog box:
Create new file
"
-z --custom_parameter_2 -z custom_parameter_3" doesn't exist. Create it? Yes No
This is not expected. The Notepad++ should not proceed to open anything. Just open an empty tab instance would be enough.
I suspect the Notepad++ tries to detect the rest of the command line after a random file parameter as a path to a file.
Suggestion: May be command line cleanup in the default exception handler would be enough.
@andry81 The user manual states: The only intended and supported use for this option is for the Notepad Replacement syntax.. Thus, don't do what you're doing with -z.
You could try -pluginMessage="text for plugin(s)" instead...

It works as expected. Don't see a problem here.
The problem is with a not catched exception, which alters the behavior.

Ok, but not sure how far anyone here will attempt to carry support along, for an unsupported usage.

Well, are you trying to catch it in the Python? Really, you don't show much of anything in your writeup of this issue.
