Trimming the ends of a string
User input is usually messy, including additional spaces before or after the text that matters. This recipe shows how to use the string trimming functions for this purpose.
How to do it...
Use the strings.Trim family of functions, as shown here:
package main
import (
"fmt"
"strings"
)
func main() {
fmt.Println(strings.TrimRight("Break-------", "-"))
// Break
fmt.Println(strings.TrimRight("Break with spaces-- -- --", "- "))
// Break with spaces
fmt.Println(strings.TrimSuffix("file.txt", ".txt"))
// file
fmt.Println(strings.TrimLeft(" \t Indented text", " \t"))
...
