Textwrap for javascript/nodejs. Correctly handles wide characters (宽字符) and emojis (😃). Optionally break words when wrapping strings.
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.
sh
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:
$3
js
var Smartwrap = require('smartwrap');
var exampleText1 = '宽字符';
console.log(Smartwrap(exampleText1,{
width: 2
}));
`- Output:
宽
字
符
$3
js
let exampleText2 = "break at word"console.log(smartwrap(exampleText2,{
width: 10,
breakword: false //default
}))
`- Output:
break at
word
$3
js
console.log(smartwrap(exampleText2,{
width: 10,
breakword: true
}))
`- Output:
break at w
ord
