> Split a string on a character except when the character is escaped.
|
|
|
|
Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
|
|
|
|
## Install
|
|
|
|
Install with [npm](https://www.npmjs.com/):
|
|
|
|
```sh
|
|
$ npm install --save split-string
|
|
```
|
|
|
|

|
|
Although it's easy to split on a string:
|
|
|
|
```js
|
|
console.log('a.b.c'.split('.'));
|
|
//=> ['a', 'b', 'c']
|
|
```
|
|
|
|
It's more challenging to split a string whilst respecting escaped or quoted characters.
|
|
|
|
**Bad**
|
|
|
|
```js
|
|
console.log('a\\.b.c'.split('.'));
|
|
//=> ['a\\', 'b', 'c']
|
|
|
|
console.log('"a.b.c".d'.split('.'));
|
|
//=> ['"a', 'b', 'c"', 'd']
|
|
```
|
|
|
|
**Good**
|
|
|
|
```js
|
|
var split = require('split-string');
|
|
console.log(split('a\\.b.c'));
|
|
//=> ['a.b', 'c']
|
|
|
|
console.log(split('"a.b.c".d'));
|
|
//=> ['a.b.c', 'd']
|
|
```
|
|
|
|
See the [options](#options) to learn how to choose the separator or retain quotes or escaping.
|

|
## Usage
|
|
|
|
```js
|
|
var split = require('split-string');
|
|
|
|
split('a.b.c');
|
|
//=> ['a', 'b', 'c']
|
|
|
|
// respects escaped characters
|
|
split('a.b.c\\.d');
|
|
//=> ['a', 'b', 'c.d']
|
|
|
|
// respects double-quoted strings
|
|
split('a."b.c.d".e');
|
|
//=> ['a', 'b.c.d', 'e']
|
|
```
|
|
|
|
**Brackets**
|
|
|
|
Also respects brackets [unless disabled](#optionsbrackets):
|
|
|
|
```js
|
|
split('a (b c d) e', ' ');
|
|
//=> ['a', '(b c d)', 'e']
|
|
```
|
|
|
|
## Options
|
|
|
|
### options.brackets
|
|
|
|
**Type**: `object|boolean`
|
|
|
|
**Default**: `undefined`
|
|
|
|
**Description**
|
|
|
|
If enabled, split-string will not split inside brackets. The following brackets types are supported when `options.brackets` is `true`,
|
|
|
|
```js
|
|
{
|
|
'<': '>',
|
|
'(': ')',
|
|
'[': ']',
|
|
'{': '}'
|
|
}
|
|
```
|
|
|
|
Or, if object of brackets must be passed, each property on the object must be a bracket type, where the property key is the opening delimiter and property value is the closing delimiter.
|
|
|
|
**Examples**
|
|
|
|
```js
|
|
// no bracket support by default
|
|
split('a.{b.c}');
|
|
//=> [ 'a', '{b', 'c}' ]
|
|
|
|
// support all basic bracket types: "<>{}[]()"
|
|
split('a.{b.c}', {brackets: true});
|
|
//=> [ 'a', '{b.c}' ]
|
|
|
|
// also supports nested brackets
|
|
split('a.{b.{c.d}.e}.f', {brackets: true});
|
|
//=> [ 'a', '{b.{c.d}.e}', 'f' ]
|
|
|
|
// support only the specified brackets
|
|
split('[a.b].(c.d)', {brackets: {'[': ']'}});
|
|
//=> [ '[a.b]', '(c', 'd)' ]
|
|
```
|
|
|
|
### options.sep
|
|
|
|
**Type**: `string`
|
|

|
**Example**
|
|
|
|
```js
|
|
split('a.b,c', {sep: ','});
|
|
//=> ['a.b', 'c']
|
|
|
|
// you can also pass the separator as string as the last argument
|
|
split('a.b,c', ',');
|
|
//=> ['a.b', 'c']
|
|
```
|
|
|
|
### options.keepEscaping
|
|
|
|
**Type**: `boolean`
|
|
|
|

|
|
//=> ['a', 'b.c']
|
|
|
|
split('a.b.\\c', {keepEscaping: true});
|
|
//=> ['a', 'b\.c']
|
|
```
|
|
|
|
### options.keepQuotes
|
|
|
|
**Type**: `boolean`
|
|
|
|
**Default**: `undefined`
|
|
|
|
Keep single- or double-quotes in the result.
|
|
|
|
**Example**
|
|
|
|
```js
|
|
split('a."b.c.d".e');
|
|
//=> ['a', 'b.c.d', 'e']
|
|
|
|
split('a."b.c.d".e', {keepQuotes: true});
|
|
//=> ['a', '"b.c.d"', 'e']
|
|
|
|
split('a.\'b.c.d\'.e', {keepQuotes: true});
|
|
//=> ['a', '\'b.c.d\'', 'e']
|
|

|
|
### options.keepDoubleQuotes

|
|

|
|
|
split('a.\'b.c.d\'.e', {keepSingleQuotes: true});
|
|

|

tok.split = false;
|
|
}
|
|
});

console.log(arr);
