smartwrap

Textwrap for javascript/nodejs. Correctly handles wide characters (宽字符) and emojis (😃). Optionally break words when wrapping strings.

Why?

I needed a javascript package to correctly wrap wide characters - which have a "length" property value of 1 but occupy 2 or more spaces in the terminal.

Example Usages:

Terminal:

npm i -g smartwrap
echo somestring you want to wrap | smartwrap --width=3 --paddingLeft=1

Output:

 so
 me
 st
 ri
 ng
 yo
 u
 wa
 nt
 to
 wr
 ap

Node module:

Wide Character Wrapping

var Smartwrap = require('smartwrap');
var exampleText1 = '宽字符';
console.log(Smartwrap(exampleText1,{
  width: 2
}));

• Output:

宽
字
符

String Wrapping

let exampleText2 = "break at word"

console.log(smartwrap(exampleText2,{
  width: 10,
  breakword: false //default
}))

• Output:

break at
word

Breaking Words When Wrapping Strings

console.log(smartwrap(exampleText2,{
  width: 10,
  breakword: true
}))

• Output:

ord
