This file exists solely to respond to /search URL with the related search layout template.

No content shown here is rendered, all content is based in the template layouts/page/search.html

Setting a very low sitemap priority will tell search engines this is not important content.

This implementation uses Fusejs and mark.js

Initial setup

Search depends on additional output content type of JSON in config.toml ``` [outputs] home = [“HTML”, “JSON”] ```

string`

Numbers

Typical types

num := 3          // int
num := 3.         // float64
num := 3 + 4i     // complex128
num := byte('a')  // byte (alias for uint8)

Other Types

var u uint = 7        // uint (unsigned)
var p float32 = 22.7  // 32-bit float

Arrays

// var numbers [5]int
numbers := [...]int{0, 0, 0, 0, 0}

Pointers

func main () {
  b := *getPointer()
  fmt.Println("Value is", b)

func getPointer () (myPointer *int) {
  a := 234
  return &a

a := new(int)
*a = 234

Pointers point to a memory location of a variable. Go is fully garbage-collected.
