Generate regular expressions from [regjsparser][regjsparser]’s AST.
``sh`
npm i regjsgen
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);
Tested in Node.js 10, 12, 14, and 16.
Compatible with regjsparser v0.7.0’s AST.
