Dedent

Removes common leading whitespace from multiline strings. Inspired by textwrap.dedent in Python.

Usage / example

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(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.

Functions

func Dedent

func Dedent(text string) string

Dedent removes any common leading whitespace from every line in text.

This can be used to make multiline strings to line up with the left edge of the display, while still presenting them in the source code in indented form.

Example

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(s))
fmt.Println("-------------")
fmt.Println(s)

Output:

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.
