spacious_hex2rgb( $hexstr)

Hi from germany,

I’d kindly like to ask you, if you could probably add a wrapper around this function, so that I could overwrite it in a child theme:

if(! function_exists('spacious_hex2rgb')):
function spacious_hex2rgb( $hexstr) {
    ...
}
endif;

I like the Spacious Theme a lot, so I use it for projects frequently. But every now and then I run into trouble with your function, so I normally overwrite it with this more complex one:

function spacious_hex2rgb($color, $opacity = 0.85) {

    $default = 'rgb(0,0,0)';

    //Return default if no color provided
    if(empty($color)){
          return $default;
    }

    //Sanitize $color if "#" is provided
    if ($color[0] == '#' ) {
        $color = substr( $color, 1 );
    }

    //Check if color has 6 or 3 characters and get values
    if (strlen($color) == 6) {
            $hex = array( $color[0] . $color[1], $color[2] . $color[3], $color[4] . $color[5] );
    } elseif ( strlen( $color ) == 3 ) {
            $hex = array( $color[0] . $color[0], $color[1] . $color[1], $color[2] . $color[2] );
    } else {
            return $default;
    }

    //Convert hexadec to rgb
    $rgb =  array_map('hexdec', $hex);

    //Check if opacity is set(rgba or rgb)
    if($opacity){
        if(abs($opacity) > 1){
            $opacity = 1.0;
        }
        $output = 'rgba('.implode(",",$rgb).','.$opacity.')';
    } else {
        $output = 'rgb('.implode(",",$rgb).')';
    }

    //Return rgb(a) color string
    return $output;
}

With every theme update I have to fix that again, which is a bit annoying ??

Thanks for your effort and for considering my suggestion.
