@babel/plugin-transform-dotall-regex

信息

This plugin is included in @babel/preset-env, in ES2018

This plugin transforms regular expression literals to support the /s flag. It does not patch the new RegExp constructor, since its arguments cannot be pre-transformed statically: to handle runtime behavior of functions/classes, you will need to use a polyfill instead.

Example

In

JavaScript

/./s;

Out

JavaScript

/[\0-\uFFFF]/;

In

JavaScript

/./su;

Out

JavaScript

/[\0-\u{10FFFF}]/u;

Here’s an online demo.
