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

```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 in Node.js 10, 12, 14, and 16.<br>
Compatible with regjsparser v0.7.0’s AST.
