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: <20>]
|
||
--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"]]
