我试图清理一下我主题中的代码，删除一些未使用的代码，基本上以正确的方式做事，以减少加载时间等。

目前我有以下代码：

add_action(\'after_setup_theme\', \'rm_theme_setup\');

// start theme setup
function rm_theme_setup() {
    add_action(\'init\', \'rm_head_cleanup\'); // * 1) calling the function below
    add_action(\'wp_head\', \'rm_remove_recent_comments_style\', 1);
    add_filter(\'gallery_style\', \'rm_remove_gallery_style\');

    rm_add_theme_support(); // * 2) calling the function to add theme support
}

1) This is the wp_head cleanup part: 基本上，我在上面的theme\\u setup函数中调用这个函数。这是正确的做事方式吗？

function rm_head_cleanup() {
    remove_action(\'wp_head\', \'feed_links_extra\', 3);
    remove_action(\'wp_head\', \'feed_links\', 2);
    remove_action(\'wp_head\', \'rsd_link\');
    remove_action(\'wp_head\', \'wlwmanifest_link\');
    remove_action(\'wp_head\', \'index_rel_link\');
    remove_action(\'wp_head\', \'parent_post_rel_link\', 10, 0);
    remove_action(\'wp_head\', \'start_post_rel_link\', 10, 0);
    remove_action(\'wp_head\', \'adjacent_posts_rel_link_wp_head\', 10, 0);
    remove_action(\'wp_head\', \'wp_generator\');
    remove_action(\'wp_head\', \'wp_shortlink_wp_head\');
    add_filter(\'style_loader_src\', \'rm_remove_wp_ver_css_js\');
    add_filter(\'style_loader_tag\', \'rm_clean_style_tags\');
    add_filter(\'script_loader_src\', \'rm_remove_wp_ver_css_js\');
}

2) 后来在代码中我有了这个函数，to add theme support. 当您检查主题设置功能时，我只是这样做：rm\\u add\\u theme\\u support（）；。这是正确的方法吗，还是我应该复制此功能中的所有内容并将其粘贴到theme\\u设置？

function rm_add_theme_support() {
add_theme_support(\'post-thumbnails\');

// remove the default thumbnails
update_option(\'thumbnail_size_h\', 0);
update_option(\'thumbnail_size_w\', 0);
update_option(\'medium_size_h\', 0);
update_option(\'medium_size_w\', 0);
update_option(\'large_size_h\', 0);
update_option(\'large_size_w\', 0);

// set_post_thumbnail_size(200, 200, true);
add_image_size(\'rm-slide\', 960, 500);
add_image_size(\'rm-service-image\', 380, 9999);
add_image_size(\'rm-service-thumbnail\', 80, 60, true);

add_theme_support(\'menus\');

register_nav_menus(
    array(
        \'main-nav\' => \'Main menu\'
    )
);

}

感谢所有的帮助，希望这不是太多的代码。
