Sorting slices

The sorting of data is a very common task. The Go standard library simplifies the sorting by the sort package. This recipe gives a brief look at how to use it.

How to do it...

1. Open the console and create the folder chapter11/recipe07.
2. Navigate to the directory.
3. Create the file sort.go with the following content:

        package main

        import (
          "fmt"
          "sort"
        )

        type Gopher struct {
          Name string
          Age int
        }

        var data = []Gopher{
          {"Daniel", 25},
          {"Tom", 19},
          {"Murthy", 33},
        }

        type Gophers []Gopher

        func (g Gophers) Len() int {
          return len(g)
        }

        func (g Gophers) Less(i, j int) bool {
          return g[i].Age > g[j].Age
        }

        func (g Gophers) Swap(i, j int) {
          tmp := g[j]
          g[j] = g[i]
          g[i] = tmp
        }

        func main() {

          sort.Slice(data, func(i, j int) bool {
        ...
