RegExp.prototype.flags

An ES6 spec-compliant RegExp.prototype.flags shim. Invoke its "shim" method to shim RegExp.prototype.flags if it is unavailable.Note: RegExp#flags requires a true ES5 environment - specifically, one with ES5 getters.

This package implements the es-shim API interface. It works in an ES5-supported environment and complies with the spec.

Most common usage:

var flags = require('regexp.prototype.flags'); var assert = require('assert');

assert(flags(/a/) === ''); assert(flags(new RegExp('a')) === ''); assert(flags(/a/mig) === 'gim'); assert(flags(new RegExp('a', 'mig')) === 'gim');

if (!RegExp.prototype.flags) { flags.shim(); }

assert(flags(/a/) === /a/.flags); assert(flags(new RegExp('a')) === new RegExp('a').flags); assert(flags(/a/mig) === /a/mig.flags); assert(flags(new RegExp('a', 'mig')) === new RegExp('a', 'mig').flags);
