Here’s how I recommend using the class.
<ol>
<li>Either activate this plugin, or include the class in your own plugin file.</li>
<li>When you start to render the page with the post list, instantiate the pagination class, using an argument array if you’d like: $pargs = array( ‘get_per_page_key’ => ‘perpage’, ‘get_paged_key’ => ‘current_page’, ‘per_page’ => 15 ); $pagination = new BBG_CPT_Pag( $args );</li>
<li>When constructing your query arguments (for query_posts() or WP_Query), you can use the class to get your pagination arguments out of the $_GET parameters. For instance: $args = array( … ‘posts_per_page’ => $pagination->get_per_page, ‘paged’ => $pagination->get_paged … ); query_posts( $args );</li>
<li>After firing the query, use the <code>setup_query()</code> method to populate the rest of the class. If you used <code>query_posts()</code>, you don’t need an argument: $pagination->setup_query(); If you use <code>new WP_Query</code>, you’ll have to pass the query object: $my_query = new WP_Query; $pagination->setup_query( $my_query );</li>
<li>Then you can use all sorts of fun methods, like $pagination->paginate_links(); $pagination->currently_viewing_text();</li>
</ol>

Boone's Pagination

A handy, extensible class for paginating your custom post type lists.

This plugin is primarily aimed at theme developers, and intends to ease the 
creation of semantic, usable pagination controls for WordPress listings pages, such as 
arhive, author, category, search, tag listings etc.
Inspired by <a href="https://codex.wordpress.org/The_Loop" rel="nofollow ugc">The Loop</a> and <a href="https://codex.wordpress.org/Function_Reference/WP_Query" rel="nofollow ugc">WP_Query</a>, this plugin stays out of the theme 
developer’s way, allowing her to create the markup needed by providing the 
following template tags:
<ul>
<li><code>pp_has_pagination</code> – determines whether the current ‘view’ has any pagination to display, i.e. whether the content being browsed spans more than 1 page</li>
<li><code>pp_the_pagination</code> – initiates the pagination context, should be called at the beginning of each loop iteration</li>
<li><code>pp_rewind_pagination</code> – resets the pagination context, so that the pagination loop can be iterated over multiple times</li>
<li><code>pp_is_current_page</code> – for use in the pagination loop, returns a boolean indicating whether the current loop iteration is for the current page</li>
<li><code>pp_has_previous_page</code> – for use in the pagination loop, returns a boolean indicating whether there is a previous page, e.g. when at page 1, there is no previous page</li>
<li><code>pp_has_next_page</code> – for use in the pagination loop, returns a boolean indicating whether there is a next page, e.g. when at page N of N, there is no next page</li>
<li><code>pp_the_page_permalink</code> – for use in the pagination loop, echos the permalink for the current page</li>
<li><code>pp_the_previous_page_permalink</code> – for use in the pagination loop, echos the permalink for the previous page</li>
<li><code>pp_the_next_page_permalink</code> – for use in the pagination loop, echos the permalink for the next page</li>
<li><code>pp_the_first_page_permalink</code> – for use in the pagination loop, echos the permalink for the first page</li>
<li><code>pp_the_last_page_permalink</code> – for use in the pagination loop, echos the permalink for the last page</li>
<li><code>pp_the_page_num</code> – for use in the pagination loop, echos the page number of the current page being iterated over</li>
</ul>
For example, the following arrangement of template tags would provide a rudimentary pagination control:
<pre><code><?php if (pp_has_pagination()) : ?>
 <div class="pagination">

 
 <?php pp_the_pagination(); if (pp_has_previous_page()) : ?>
 <a href="<?php pp_the_previous_page_permalink(); ?>" class="prev">newer stories</a>
 <?php else : ?>
 newer stories
 <?php endif; pp_rewind_pagination(); ?>

 
 <?php while(pp_has_pagination()) : pp_the_pagination(); ?>
 <?php if (pp_is_current_page()) : ?>
 <?php pp_the_page_num(); ?>
 <?php else : ?>
 <a href="<?php pp_the_page_permalink(); ?>"><?php pp_the_page_num(); ?></a>
 <?php endif; ?>
 <?php endwhile; pp_rewind_pagination(); ?>

 
 <?php pp_the_pagination(); if (pp_has_next_page()) : ?>
 <a href="<?php pp_the_next_page_permalink(); ?>" class="next">older stories</a>
 <?php else : ?>
 older stories
 <?php endif; pp_rewind_pagination(); ?>

 </div>
<?php endif; ?>
</code></pre>
The template tags on offer by this plugin provide the theme developer with an 
unlimited array of possibilities for marking up the pagination control in a 
semantic manner.
