Motivation

Sometimes, strings contain data that's structured in such a way, that the relevant piece of information is between two - usually symmetrical - delimiters characters (parenthesis, brackets...)

When trying to extract it, you're thinking... cool, let's use a regex

After 30 minutes of failed attempts, you decide to look it up on stackoverflow, where someone - several people actually - casually suggest to use something like (?:(?<=().+?(?=))|(?<=[).+?(?=])), like a random monday morning. sigh

Have you ever done this? Well, I have. So I decided to roll up my own non-regexp function to just do that, and never have to think about it again.

Unbracket

Default usage

Meet the unbracket package. A simple "unbracketter" without regexp that just works

const unbracket = require("unbracket")
const string = "I don't (really) think that you should do this (crazy) thing"
const thoughts = unbracket.withParenthesis(string) // ["really", "crazy"]

API

The API contains all the common delimiters along with custom one

unbracket.withBrackets(<String>)
unbracket.withCurlyBraces(<String>)
unbracket.withRafters(<String>)
unbracket.withCustom(<String>, OPENING_DELIMITER, CLOSING_DELIMITER)

Limitations

Unbracket has zero opinion on how to deal with nested delimiters:

const unbracket = require("unbracket")
const string = "GroupA(Jean, Jack(Gold, Man)), GroupB(Ben)"
const thoughts = unbracket.withParenthesis(string) // ["Jean, Jack(Gold, Man)", "Ben"]
