The opts module

This module contains a bunch of commonly used options. It covers settings for the various Widgets of Duat, most notably the Buffer widget, which is where editing takes place.

        // Allow scrolling until the Buffer shows only scrolloff.y lines.

        opts.main_align = std::fmt::Alignment::Right;
        // Place the LineNumbers on the right of the Buffer, instead of on the left.
        opts.on_the_right = false;
    });

    // Sets a Kakoune style "one line" footer
    opts::one_line_footer(false);

    // Place the footer on top, instead of on the bottom of the screen.
    opts::footer_on_top(false);

    // Default options for the StatusLine widget
    opts::set_status(|pa| {
        // If on one line footer mode:
        let mode = mode_txt();
        let param = duat_param_txt();
        status!("{AlignRight}{name_txt} {mode} {sels_txt} {param} {main_txt}");
        // If on regular mode (default):
        let mode = mode_txt();
        let param = duat_param_txt();
        status!("{mode} {name_txt}{Spacer}{sels_txt} {param} {main_txt}")
    });

    // Default options for the LogBook widget
    opts::set_logs(|opts| {});

    // Default options for the Notifications widget
    opts::set_notifs(|opts| {});
