@babel/plugin-transform-unicode-property-regex
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.
安装
¥Installation
- npm

用法
¥Usage
使用配置文件(推荐)
¥With a configuration file (Recommended)
{
"plugins": ["@babel/plugin-transform-unicode-property-regex"]
}
通过 CLI
¥Via CLI
babel --plugins @babel/@babel/plugin-transform-unicode-property-regex script.js

¥Via Node.js API
require("@babel/core").transformSync(code, {
plugins: ["@babel/plugin-transform-unicode-property-regex"],
});
转译为 ES6/ES2015:
¥To transpile to ES6/ES2015:
require("@babel/core").transformSync(code, {
plugins: [
[
"@babel/plugin-transform-unicode-property-regex",
{ useUnicodeFlag: false },
],
],
});
选项
¥Options
-
useUnicodeFlag
(默认为true
)¥
useUnicodeFlag
(defaults totrue
)
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.
