Prerequisite

Usage

By default, multiline detects indentation by looking at the first non-empty line. Notice that the first empty line is dropped from the output to let you to start the first line with the indentation level you like.

const multiline = require('multiline-string')()

const s = multiline(`
            1. xxx
              a. yyy
            2. zzz
            `)

console.log(s)
// => "1. xxx\n  a. yyy\n2. zzz"

If you want to start your string with an empty line, you can do:

const s = multiline(`

            Line 1
            Line 2
            `)
// => "\nLine 1\nLine 2\n"

You can also give marginMark to identify the start of each line to include indentation in the resulting text.

const multiline = require('multiline-string')({ marginMark: '|' })

const s = multiline(`
            |  Usage: my-command file
            |
            |    -v, --version    Show version
            |    -h, --help       Show help information
            |`)

console.log(s)
// => "  Usage: ...\n\n    -v, --version ..."
