split-string

Split a string on a character except when the character is escaped.

Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your :heart: and support.

Install

Install with npm:

$ npm install --save split-string

Why use this?

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

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:

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,

{
  '<': '>',
  '(': ')',
  '[': ']',
  '{': '}'
}

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

// 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

Default: .

The separator/character to split on.

Example

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

Default: undefined

Keep backslashes in the result.

Example

split('a.b\\.c');
//=> ['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

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

Type: boolean

Default: undefined

Keep double-quotes in the result.

Example

split('a."b.c.d".e');
//=> ['a', 'b.c.d', 'e']

split('a."b.c.d".e', {keepDoubleQuotes: true});
//=> ['a', '"b.c.d"', 'e']

options.keepSingleQuotes

Type: boolean

Default: undefined

Keep single-quotes in the result.

Example

split('a.\'b.c.d\'.e');
//=> ['a', 'b.c.d', 'e']

split('a.\'b.c.d\'.e', {keepSingleQuotes: true});
//=> ['a', '\'b.c.d\'', 'e']

Customizer

Type: function

Default: undefined

Pass a function as the last argument to customize how tokens are added to the array.

Example

var arr = split('a.b', function(tok) {
  if (tok.arr[tok.arr.length - 1] === 'a') {
    tok.split = false;
  }
});
console.log(arr);
//=> ['a.b']

Properties

The tok object has the following properties:

• tok.val (string) The current value about to be pushed onto the result array
• tok.idx (number) the current index in the string
• tok.str (string) the entire string
• tok.arr (array) the result array
