[feature] pagination for posts summary

[kwladyka]

Currently there is a way to do prev / next but not 0, 1, 2, ...

    <div id="prev-next">
        {% if prev-uri %}
        <a class="button left" href="{{prev-uri}}">&laquo; Prev</a>
        {% endif %}
        {% if next-uri %}
        <a class="button right" href="{{next-uri}}">Next &raquo;</a>
        {% endif %}
    </div>

I would like to add numbers between prev and next like in the example below.

To make it possible we need to add data to Selmer with page index, URL, is page active.

Here is a Hugo example:

{{ if gt $paginator.TotalPages 1 }}
<nav>
    <ul class="pagination justify-content-center" style="flex-wrap: wrap">
        <li class="page-item{{ if not $paginator.HasPrev }} disabled {{ end }}">
            <a class="page-link" href="{{ if $paginator.HasPrev }}{{ $paginator.Prev.URL }}{{ end }}">
                <span aria-hidden="true">&laquo;</span>
            </a>
        </li>
        {{ range .Paginator.Pagers }}
        <li class="page-item{{ if eq . $paginator }} active{{ end }}"><a class="page-link" href="{{ .URL }}">{{ .PageNumber }}</a></li>
        {{ end }}
        <li class="page-item{{ if not $paginator.HasNext }} disabled {{ end }}">
            <a class="page-link" href="{{ if $paginator.HasNext }}{{ $paginator.Next.URL }}{{ end }}">
                <span aria-hidden="true">&raquo;</span>
            </a>
        </li>
    </ul>
</nav>
{{ end }}

This is the part which Cryogen doesn't have:

        {{ range .Paginator.Pagers }}
        <li class="page-item{{ if eq . $paginator }} active{{ end }}"><a class="page-link" href="{{ .URL }}">{{ .PageNumber }}</a></li>
        {{ end }}

So we need something in that taste.

Could you use :extend-params-fn to add the pagination data you want so that you could use it in your Selmer templates? See http://cryogenweb.org/docs/customizing-cryogen.html
