2868 * an unordered HTML list.
2870 * The 'total' argument is the total amount of pages and is an integer. The
2871 * 'current' argument is the current page number and is also an integer.
2873 * An example of the 'base' argument is "http://example.com/all_posts.php%_%"
2874 * and the '%_%' is required. The '%_%' will be replaced by the contents of in
2875 * the 'format' argument. An example for the 'format' argument is "?page=%#%"
2876 * and the '%#%' is also required. The '%#%' will be replaced with the page
2879 * You can include the previous and next links in the list by setting the
2880 * 'prev_next' argument to true, which it is by default. You can set the
2881 * previous text, by using the 'prev_text' argument. You can set the next text
2882 * by setting the 'next_text' argument.
2884 * If the 'show_all' argument is set to true, then it will show all of the pages
2885 * instead of a short list of the pages near the current page. By default, the
2886 * 'show_all' is set to false and controlled by the 'end_size' and 'mid_size'
2887 * arguments. The 'end_size' argument is how many numbers on either the start
2888 * and the end list edges, by default is 1. The 'mid_size' argument is how many
2889 * numbers to either side of current page, but not including current page.
2891 * It is possible to add query vars to the link by using the 'add_args' argument
2892 * and see {@link add_query_arg()} for more information.
2894 * The 'before_page_number' and 'after_page_number' arguments allow users to
2895 * augment the links themselves. Typically this might be to add context to the
2896 * numbered links so that screen reader users understand what the links are for.
