split-string 
Split a string on a character except when the character is escaped.
Why use this?
Although it's easy to split on a string:
console.log('a.b.c'.split('.'));
//=> ['a', 'b', 'c']
It's more challenging to split a string whilst respecting escaped or quoted characters.
Bad
console.log('a\\.b.c'.split('.'));
//=> ['a\\', 'b', 'c']
console.log('"a.b.c".d'.split('.'));
//=> ['"a', 'b', 'c"', 'd']
Good
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 to learn how to choose the separator or retain quotes or escaping.
Install
Install with npm:
$ npm install --save split-string
Install with yarn:
$ yarn add split-string
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']
Options
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 arraytok.idx(number) the current index in the stringtok.str(string) the entire stringtok.arr(array) the result array
