Generate regular expressions from [regjsparser][regjsparser]’s AST.

## Installation

```sh

npm i regjsgen

## API

### `regjsgen.generate(ast)`

This function accepts an abstract syntax tree representing a regular expression (see [regjsparser][regjsparser]), and returns the generated regular expression string.

```js

const regjsparser = require('regjsparser');

const regjsgen = require('regjsgen');

// Generate an AST with `regjsparser`.

let ast = regjsparser.parse(regex);

// Modify AST

// …

// Generate `RegExp` string with `regjsgen`.

let regex = regjsgen.generate(ast);

```

## Support

Tested on Node.js 16 and 18.


Compatible with regjsparser v0.10.0’s AST.
