go get github.com/Unknwon/paginater
The following code shows an example of how to use paginater:
package main
import "github.com/Unknwon/paginater"
func main() {
// Arguments:
// - Total number of rows
// - Number of rows in one page
// - Current page number
// - Number of page links to be displayed
p := paginater.New(45, 10, 3, 3)
// Then use p as a template object named "Page" in "demo.html"
// ...
}demo.html
{{if gt .Page.TotalPages 1}}
<div class="pagination">
<div class="page-container clearfix">
{{$prefix:=.PageListURL}}
{{if .Page.HasPrevious}}<div class="page-link-prev fl"><a href='{{printf "%s%v" $prefix .Page.Previous}}'></a></div>{{end}}
<div class="page-links fl">
{{range .Page.Pages}}
{{if le .Num 0}}
{{else}}
{{if .IsCurrent}}
<strong>{{.Num}}</strong>
{{else}}
<a href='{{printf "%s%v" $prefix .Num}}'>{{.Num}}</a>
{{end}}
{{end}}
{{end}}
</div>
{{if .Page.HasNext}}<div class="page-link-next fl"><a href='{{printf "%s%v" $prefix .Page.Next}}'></a></div>{{end}}
</div>
</div>
{{end}}Possible output:
[First](1) [Previous](2) ... 2 3(current) 4 ... [Next](4) [Last](5)
As you may guess, if the Page value is -1, you should print ... in the HTML as common practice.
