| 13 | An ES6 spec-compliant `RegExp.prototype.flags` shim. Invoke its "shim" method to shim RegExp.prototype.flags if it is unavailable.
|
|---|
| 14 | *Note*: `RegExp#flags` requires a true ES5 environment - specifically, one with ES5 getters.
|
|---|
| 15 |
|
|---|
| 16 | This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES5-supported environment and complies with the [spec](http://www.ecma-international.org/ecma-262/6.0/#sec-get-regexp.prototype.flags).
|
|---|
| 17 |
|
|---|
| 18 | Most common usage:
|
|---|
| 19 | ```js
|
|---|
| 20 | var flags = require('regexp.prototype.flags');
|
|---|
| 21 |
|
|---|
| 22 | assert(flags(/a/) === '');
|
|---|
| 23 | assert(flags(new RegExp('a') === '');
|
|---|
| 24 | assert(flags(/a/mig) === 'gim');
|
|---|
| 25 | assert(flags(new RegExp('a', 'mig')) === 'gim');
|
|---|
| 26 |
|
|---|
| 27 | if (!RegExp.prototype.flags) {
|
|---|
| 28 | flags.shim();
|
|---|
| 29 | }
|
|---|
| 30 |
|
|---|
| 31 | assert(flags(/a/) === /a/.flags);
|
|---|
| 32 | assert(flags(new RegExp('a') === new RegExp('a').flags);
|
|---|
| 33 | assert(flags(/a/mig) === /a/mig.flags);
|
|---|
| 34 | assert(flags(new RegExp('a', 'mig')) === new RegExp('a', 'mig').flags);
|
|---|
| 35 | ```
