@babel/plugin-transform-unicode-property-regex

信息

此插件包含在 @babel/preset-env 中，在 ES2018 中

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

此插件转换正则表达式字面量以支持 \p{...} 转义。它不会修补 new RegExp 构造函数，因为它的参数不能静态地预先转换：要处理函数/类的运行时行为，你需要改用 polyfill。

¥This plugin transforms regular expression literals to support the \p{...} escapes. 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.

这是一个在线演示。

¥Here’s an online demo.

安装​

¥Installation

npm install --save-dev @babel/plugin-transform-unicode-property-regex

用法​

¥Usage

¥With a configuration file (Recommended)

babel.config.json
{
  "plugins": ["@babel/plugin-transform-unicode-property-regex"]
}

通过 CLI​

¥Via CLI

Shell
babel --plugins @babel/@babel/plugin-transform-unicode-property-regex script.js

通过 Node.js API​

¥Via Node.js API

JavaScript
require("@babel/core").transformSync(code, {
  plugins: ["@babel/plugin-transform-unicode-property-regex"],
});

转译为 ES6/ES2015：

¥To transpile to ES6/ES2015:

JavaScript
require("@babel/core").transformSync(code, {
  plugins: [
    [
      "@babel/plugin-transform-unicode-property-regex",
      { useUnicodeFlag: false },
    ],
  ],
});

选项​

¥Options

  • useUnicodeFlag（默认为 true）

    ¥useUnicodeFlag (defaults to true)

当使用 false 禁用时，转换会将 Unicode 正则表达式转换为非 Unicode 正则表达式以获得更广泛的支持，同时删除 u 标志。有关详细信息，请参阅 https://github.com/mathiasbynens/regexpu-core#useunicodeflag-default-false。

¥When disabled with false, the transform converts Unicode regexes to non-Unicode regexes for wider support, removing the u flag. See https://github.com/mathiasbynens/regexpu-core#useunicodeflag-default-false for more information.
