A node rewrite of perls Text::Balanced Balanced Brackets module
Homepage Repository npm Download
npm install balanced-brackets@1.2.0
This is a pertial rewrite of the perl Text::Balanced module, especially for balanced brackets.
const BalancedBrackets = require('balanced-brackets');
let balanced = new BalancedBrackets(str);
let obj = balanced.extractBracketed(strOfBrackets [, prefix]);
balanced-brackets takes a string in it's constructor, generally one containing brackets, and then calls extractBracketed with a string of brackets to find e.g. '(){}<>[]' and an optional prefix regex of things to ignore before search for the brackets. The function will return an object:
{
extracted: ,
remainder: ,
skipped: ,
}
The object keeps it's place in the string, meaning you can find more than one set of brackets within the string, by looping over the function:
const BalancedBrackets = require('balanced-brackets');
const balanced = new BalancedBrackets('(abcd) 123 (efgh)');
while (true) {
let obj = balanced.extractBracketed('()', /[a-z0-9\s]*/i);
if (!obj.extracted) {
break;
} else {
actual.push(obj.extracted);
}
}
Where obj would be an array of:
[
(abcd),
(efgh)
]
