I'm starting out with GtkD and have this function:

void main(string[] args) {
    Main.init(args);
    auto game = new GameWindow();
    Main.run();
}

and this method:

    void quit(Widget widget) {
        Main.quit();
    }

When I run dscanner --styleCheck it reports:

./src/app.d(10:10)[warn]: Variable game is never used.
./src/app.d(22:22)[warn]: Parameter widget is never used.

These are correct. However, is it possible to switch them off individually?

(In Python you can switch off lint checks using a special text in a comment at the end of the line.)

Yes you can but in the present case the analysis is right because you can write

    void main(string[] args) {
        Main.init(args);
        new GameWindow();
        Main.run();
    }

and for the other

    void quit(Widget) {
        Main.quit();
    }

or even

    void quit() {
        Main.quit();
    }

Otherwise here is an example of how you can tune the different checks:

Thank you, I made the code changes and am reading the docs you linked to.

With DLS, you can use @suppress in comment:

void quit(Widget widget) // @suppress(dscanner.suspicious.unused_parameter)
{
    Main.quit();
}

more info: https://code.dlang.org/packages/dls

Simply install the extension to your editor.
