jonschlinkert/split-string: Split a string on a given character or characters, with support for escaping.

Easy way to split a string on a given character unless it's quoted or escaped.

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

Install with npm:

$ npm install --save split-string

const split = require('split-string');

console.log(split('a.b.c'));
//=> ['a', 'b', 'c']

// respects escaped characters
console.log(split('a.b.c\\.d'));
//=> ['a', 'b', 'c.d']

// respects double-quoted strings
console.log(split('a."b.c.d".e'));
//=> ['a', '"b.c.d"', 'e']

Type: Array|Boolean

Default: []

Description

Tell split-string not to split inside any of the quote characters specified on the quotes option. Each character signifies both the "opening" and "closing" character to use.

// default behavior
console.log(split('a.b."c.d.e.f.g".h.i'));
//=> [ 'a', 'b', '"c', 'd', 'e', 'f', 'g"', 'h', 'i' ]

// with quotes
console.log(split('a.b."c.d.e.f.g".h.i', { quotes: ['"'] }));
//=> [ 'a', 'b', '"c.d.e.f.g"', 'h', 'i' ]

// escaped quotes will be ignored
console.log(split('a.b.\\"c.d."e.f.g".h.i', { quotes: ['"'] }));
//=> [ 'a', 'b', '"c', 'd', '"e.f.g"', 'h', 'i' ]

// example of how to exclude non-escaped quotes from the result
let keep = (value, state) => {
  return value !== '\\' && (value !== '"' || state.prev() === '\\');
};
console.log(split('a.b.\\"c.d."e.f.g".h.i', { quotes: ['"'], keep }));
//=> [ 'a', 'b', '"c', 'd', 'e.f.g', 'h', 'i' ]

Type: Object|Boolean

Default: {}

Description

By default, no special significance is given to bracket-like characters (such as square brackets, curly braces, angle brackets, and so on).

// default behavior
console.log(split('a.{b.c}.{d.e}'));
//=> [ 'a', '{b', 'c}', '{d', 'e}' ]

When options.brackets is true, the following brackets types are supported:

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

For example:

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

Alternatively, an object of brackets may be passed, where each key is the opening bracket and each value is the corresponding closing bracket. Note that the key and value must be different characters. If you want to use the same character for both open and close, use the quotes option.

Examples

// no bracket support by default
console.log(split('a.{b.c}.[d.e].f'));
//=> [ 'a', '{b', 'c}', '[d', 'e]', 'f' ]

// tell split-string not to split inside curly braces
console.log(split('a.{b.c}.[d.e].f', { brackets: { '{': '}' }}));
//=> [ 'a', '{b.c}', '[d', 'e]', 'f' ]

// tell split-string not to split inside any of these types: "<>{}[]()"
console.log(split('a.{b.c}.[d.e].f', { brackets: true }));
//=> [ 'a', '{b.c}', '[d.e]', 'f' ]

// ...nested brackets are also supported
console.log(split('a.{b.{c.d}.e}.f', { brackets: true }));
//=> [ 'a', '{b.{c.d}.e}', 'f' ]

// tell split-string not to split inside the given custom types
console.log(split('«a.b».⟨c.d⟩.[e.f]', { brackets: { '«': '»', '⟨': '⟩' } }));
//=> [ '«a.b»', '⟨c.d⟩', '[e', 'f]' ]

Type: function

Default: Function that returns true if the character is not \\.

Function that returns true when a character should be retained in the result.

Example

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

// keep all characters
console.log(split('a.b.\\c', { keep: () => true })); //=> ['a', 'b\.c']

Type: string

Default: .

The character to split on.

Example

console.log(split('a.b,c', { separator: ',' })); //=> ['a.b', 'c']

Optionally pass a function as the last argument to tell split-string whether or not to split when the specified separator is encountered.

Example

// only split on "." when the "previous" character is "a"
console.log(split('a.b.c.a.d.e', state => state.prev() === 'a'));
//=> [ 'a', 'b.c.a', 'd.e' ]

The state object exposes the following properties:

input - (String) The un-modified, user-defined input string
separator - (String) the specified separator to split on.
index - (Number) The current cursor position
value - (String) The character at the current index
bos - (Function) Returns true if position is at the beginning-of-string
eos - (Function) Returns true if position is at the end-of-string
prev - (Function) Returns the previously scanned character
next - (Function) Returns the next character after the current position
block - (Object) The "current" AST node.
stack - (Array) AST nodes
