Removes common leading whitespace from multiline strings. Inspired by textwrap.dedent in Python.
Imagine the following snippet that prints a multiline string. You want the indentation to both look nice in the code as well as in the actual output.
package main
import (
"fmt"
"github.com/lithammer/dedent"
)
func main() {
s := `
Lorem ipsum dolor sit amet,
consectetur adipiscing elit.
Curabitur justo tellus, facilisis nec efficitur dictum,
fermentum vitae ligula. Sed eu convallis sapien.`
fmt.Println(dedent.Dedent(s))
fmt.Println("-------------")
fmt.Println(s)
}To illustrate the difference, here's the output:
$ go run main.go
Lorem ipsum dolor sit amet,
consectetur adipiscing elit.
Curabitur justo tellus, facilisis nec efficitur dictum,
fermentum vitae ligula. Sed eu convallis sapien.
-------------
Lorem ipsum dolor sit amet,
consectetur adipiscing elit.
Curabitur justo tellus, facilisis nec efficitur dictum,
fermentum vitae ligula. Sed eu convallis sapien.MIT
