Can not launch okular installed with Flatpack, even with an alias added to .bashrc

[Gabriel-p]

I've installed Okular via Flathub (https://flathub.org/apps/details/org.kde.okular), and then I added the following alias to my .bashrc file:

alias okular='flatpak run org.kde.okular'

and also to my .zshrc file. This works fine, and I am able to launch Okular via terminal with the okular command.

But LatexTools is not able to launch Okular after compiling the PDF (which it did just fine with the old version installed through apt-get). The console shows this error:

I'm guessing ST does not read .bashrc, so you need to create a script somewhere on your path that runs "flatpak run org.kde.okular" and is called "okular"

As I recall, Okular was actually the software I used to test the Command Viewer, which you can read about in the docs. The example at the bottom of the page should give you some idea about how to use it.

@ig0774 Okular does work without issues if I install it via sudo apt install okular. The problem is with the flathub installation of Okular. Then ST+LateXTools does not seem to be able to find it, even if an alias is added to .bashrc.

Managed to fix it using:

// ------------------------------------------------------------------
// Viewer settings
// ------------------------------------------------------------------
    // OPTION: "viewer"
    // Specifies which viewer to use
    "viewer": "command",

    // OPTION: "viewer_settings"
    "viewer_settings": {
        // Platform-specific settings:
        "linux" : {
            // See README or third-party documentation
            "view_command": "flatpak run org.kde.okular"
        }
    }
