How to truncate a string in a Golang template

Question

In golang, is there a way to truncate text in an html template?

For example, I have the following in my template:

{{ range .SomeContent }}
 ....
             


        

Answer 1

str := "xxxx"
n := 2
if len(str) > n {
    fmt.Println(str[:n])
}

lest say we need quarter of ascii string

str[:len(str)/4]
