Theme Tag functionality [Info]

[grappler]

"The theme tags in style.css and description must match the what the theme actually does in respect to functionality and design."

Add checks for

• buddypress - I am not sure what the best check is here.
• featured-images add_theme_support( 'post-thumbnails' );
• custom-header add_theme_support( 'custom-header' );
• custom-background add_theme_support( 'custom-background' );
• custom-menu register_nav_menus()
• editor-style add_editor_style()
• flexible-header "Uses ‘flex-height’ and/or ‘flex-width’ parameter of add_theme_support( 'custom-header' );"
• post-formats add_theme_support( 'post-formats' );
• theme-options add_action( 'customize_register' );
• threaded-comments wp_enqueue_script( 'comment-reply' );

Some more:

• translation-ready - load_theme_textdomain or load_child_theme_textdomain
• rtl-language-support - Check for rtl.css
• featured-image-header - This requires add_theme_support( 'post-thumbnails' ) and add_theme_support( 'custom-header' )

Those are good for info checks but they require manual checks to see if all of the strings are internationalized and that the rtl.css is not empty.

I agree that featured-image-header requires add_theme_support( 'post-thumbnails' ) but not add_theme_support( 'custom-header' ) . The theme author just needs to output the featured image in the header.
