Expressionist

Simple helper to perform basic preparations on strings to use them in Regular Expressions.

Getting started

Installation

$ npm install --save @konfirm/expressionist

Usage

const Expressionist = require('@konfirm/expressionist');

Expressionist.ungroup

Replace potential capture groups with non-capture groups, while leaving existing non-capture groups ((?:...)) and lookaheads (positive ((?=...)) and negative ((?!...))) intact.

const ungrouped = Expressionist.ungroup('(hello(world))');

console.log(ungrouped);  //  '(?:hello(?:world))

Expressionist.escape

Escape all characters with a special meaning in Regular Expressions so that these can be matched exactly

const escaped = Expressionist.escape('[email protected]');

console.log(escaped);  //  'john\.doe\+label@example\.com'
