Step 1: Initialize the pager.

import (

)

// ...total number of records under consideration
count := 100

// ...number of records per page
limit := 10

// ...current page number
number := 1

// ...size of the sliding window of page numbers
//    (on either side of the current page)
numbers := 3

// ...URL syntax
//    (%d will be replaced with the page number in context)
url := "/%d/"

p = pager.NewPager(count, limit, number, numbers, url)

Step 2: Use it in your view.

query := "SELECT * FROM ... WHERE ... ORDER BY ... LIMIT %d OFFSET %d"
query = fmt.Sprintf(query, p.Records.Limit, p.Records.Offset)

Step 3: Use it in your template.

<div>
    <p class="pagination pull-right">
        Showing {{ $.p.Records.From }} to {{ $.p.Records.To }} of {{ $.p.Records.Total }}
        records
    </p>
    <ul class="pagination">
        <li {{ if eq $.p.Pages.Number 1 }}class="disabled"{{ end }}>
            <a href="{{ $.p.GetURL $.p.Pages.First }}">
                <span>&laquo;</span>
            </a>
        </li>
        <li {{ if eq $.p.Pages.Number $.p.Pages.Previous }}class="disabled"{{ end }}>
            <a href="{{ $.p.GetURL $.p.Pages.Previous }}">
                <span>&lt;</span>
            </a>
        </li>
        {{ range $.p.Pages.Numbers }}
            <li {{ if eq $.p.Pages.Number . }}class="disabled"{{ end }}>
                <a href="{{ $.p.GetURL . }}">

            </li>

            </a>
        </li>
        <li {{ if eq $.p.Pages.Number $.p.Pages.Last }}class="disabled"{{ end }}>
