Small questions about Dangerzone 0.10.0

[DeltaEpsilon19498]

For context, I am currently running an Ubuntu-based Linux distribution.

I notice that in the Dangerzone GUI, I can either move the unsanitized document to an unsafe directory, OR I can move the sanitized document to a safe directory. I do not seem to have the option to do both. Is there a reason for this? Does dangerzone-cli have more flexibility regarding this?

I also notice that for the option to open the document after sanitization, on my current system it is only giving me the option to open the document in my web browsers. I would like the option to open it in my flatpacked Evince instead. Is there any way to get Dangerzone to recognize it as an option?

By the way, I used to use Okular instead. I notice that in Okular, the sharpness/quality of the pdf writng/images is noticably worse after sanitization. But Evince does not appear to have this problem. I have not brought it up before, since presumably it would be classified as an Okular issue, not a Dangerzone issue.

It's currently not possible to do that with the GUI, you're right. The CLI offers to option for you to specify the location of the output. Here's the current --help:

sage: dangerzone-cli [OPTIONS] [FILENAMES]...

Options:
  --output-filename TEXT        Default is filename ending with -safe.pdf
  --ocr-lang TEXT               Language to OCR, defaults to none
  --archive                     Archives the unsafe version in a subdirectory
                                named 'unsafe'
  --debug                       Run Dangerzone in debug mode, to get logs from
                                gVisor.
  --set-container-runtime TEXT  The name or full path of the container runtime
                                you want Dangerzone to use. You can specify
                                the value 'default' if you want to take back
                                your choice, and let Dangerzone use the
                                default runtime for this OS
  --linger                      Do not stop the Podman machine VM that
                                Dangerzone uses to run containers, after the
                                conversions have completed. This is useful if
                                you want to run multiple conversions in a row,
                                since the startup of the VM takes some time.
                                If you choose to let the Podman machine
                                linger, you will need to stop it manually with
                                `dangerzone-machine stop`. This option affects
                                only Windows/macOS platforms.
  --version                     Show the version and exit.
  --help                        Show this message and exit.

I also notice that for the option to open the document after sanitization, on my current system it is only giving me the option to open the document in my web browsers. I would like the option to open it in my flatpacked Evince instead. Is there any way to get Dangerzone to recognize it as an option?

On Linux, we're doing the following to find the PDF readers:

• Looking for .Desktop files that define the application/pdf mimetype. We look in /usr/share/applications , /usr/local/share/applications and ~/.local/share/applications.
• Using xdg-mime query default application/pdf to get the default one

We could look in your XDG_DATA_DIR instead to help discover these. I've created an issue about this at #1413

About Okular, I think you should open an issue there to provide them more information, if you're willing to.

And @NielDuysters just fixed it in the latest main. The fix will be out when 0.11.0 happens.

I will test it when the dangerzone is updated. In the meantime, I will look into if I can fix it myself in the settings...

Actually, dangerzone does detect evince as my preferred document reader already. It just does not display it as an option in the GUI. Here is some terminal output.

But in my GUI, it only gives me the options of Brave Web Browser, Chromium Web Browser, Firefox, and Librewolf. I am not a programmer, so I do not know if the recent change you made for version 0.11 fixes this.

As for the okular situation, I just checked, and it looks fine now. Maybe they fixed it already in a recent update.
