parenthesis

Parse parentheses from a string, return folded arrays.

var parse = require('parenthesis')

// Parse into nested format
parse('a(b[c{d}])')
// ['a(', ['b[', ['c{', ['d'], '}'], ']'], ')']

// Parse into flat format with cross-references
parse('a(b[c{d}])', {
	brackets: ['()'],
	escape: '\\',
	flat: true
})
// ['a(\\1)', 'b[c{d}]']


// Stringify nested format
parse.stringify(['a(', ['b[', ['c{', ['d'], '}'], ']'], ')'])
// 'a(b[c{d}])'

// Stringify flat format with cross-references
parse.stringify(['a(\\1)', 'b[c{d}]'], {flat: true, escape: '\\'})
// 'a(b[c{d}])'
