Filtering Shortcodes not working

[CorneliusIV]

I tried to use this example from the Readme but it does not seem to work.

    add_filter('shortcode_atts_accordion', 'set_accordion_shortcode_defaults', 10, 3);
    function set_accordion_shortcode_defaults($atts) {
        // Override the openfirst setting here
        $atts['openfirst'] = true;
        return $atts;
    }

Is shortcode_atts_accordion hook correct, I do not see any reference to it in the code?

That snippet uses the shortcode_atts_(shortcode) filter built into Wordpress.

Admittedly I haven't tested this in several years so I have no idea if it still works.

@philbuchanan thanks I didn't even realize that. Let me look into that some more.
