Well, FWIW, here's my old code.  I probably should clean up before
posting and provide some config instead of hard-coded values,  but...


[%
    # pager.tt
    #
    # Creates stash entries: (all localized)
    #   page_nav.summary    = "Viewing: 41 - 50 of 200"
    #   page_nav.previous   = "Previous" link if exists
    #   page_nav.next       = "Next" link if exists
    #   page_nav.pages      = list of pages as html

    RETURN UNLESS pager.last_page > 1;




    page_nav.summary = loc( [
        '<em>Viewing Page:</em> [_1] of [_2]',
        pager.current_page,
        pager.last_page,
    ] );



    # Create url object to modify

    USE u = URL(c.uri_path, c.req.parameters );


    IF pager.current_page > 1;
        lnk = u( p = pager.current_page - 1);
        label = loc('Previous');
        page_nav.previous = "<a href='$lnk'><em>$label</em></a>";
    END;


    IF pager.current_page < pager.last_page;
        lnk = u( p = pager.current_page + 1);
        label = loc('Next');
        page_nav.next = "<a href='$lnk'><em>$label</em></a>";
    END;

    # Set start and end position of sliding window
    IF pager.current_page <= 6;
        page_start = 1;
        page_end   = 10;
    ELSE;
        page_start = pager.current_page - 5;
        page_end   = page_start + 9;
    END;

    SET page_end = pager.last_page IF page_end > pager.last_page;


    pg = [];  # list of pages

    FOR num IN [ page_start .. page_end ];

        IF num == pager.current_page;
            pg.push( '<em>' _ num _ '</em>' );
            NEXT;
        END;

        lnk = u( p = num);
        pg.push( "<a href='$lnk'>$num</a>");
    END;

    page_nav.pages = pg;

[% BLOCK formatted_page_nav %]
    <div class="pager">
        <p>
            [% page_nav.summary %]
        </p>
        <ol>
            [%- "<li>$page_nav.previous</li>" IF page_nav.previous %]
            [%- FOR p = page_nav.pages %]
                <li>[% p %]</li>
            [%- END %]
            [%- "<li>$page_nav.next</li>" IF page_nav.next %]
