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:
```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:
### Wide Character Wrapping
```js
var Smartwrap = require('smartwrap');
var exampleText1 = '宽字符';
console.log(Smartwrap(exampleText1,{
width: 2
}));
```
- Output:
```
宽
字
符
```
### String Wrapping
```js
let exampleText2 = "break at word"
console.log(smartwrap(exampleText2,{
width: 10,
breakword: false //default
}))
```
- Output:
```
break at
word
```
### Breaking Words When Wrapping Strings
```js
console.log(smartwrap(exampleText2,{
width: 10,
breakword: true
}))
```
- Output:
```
break at w
ord
```
## Options
```sh
--breakword Choose whether or not to break words when wrapping a string
[default: false]
--errorChar Placeholder for wide characters when minWidth < 2
[default: �]
--minWidth Never change this unless you are certin you are not using
wide characters and you want a column 1 space wide. Then
change to 1. [choices: 1, 2] [default: 2]
--paddingLeft Set the left padding of the output [default: 0]
--paddingRight Set the right padding of the output [default: 0]
--splitAt Characters at which to split input [default: [" ","\t"]]
--trim Trim the whitespace from end of input [default: true]
--width, -w Set the line width of the output (in spaces)
[required] [default: 10]
```
