hints.\n- Enforces a consistent style of regular expressions.\n- Find hints for writing optimized regular expressions.\n- 80 plugin rules for regular expression syntax and features.\n\nYou can check

plugins section of your `eslint.config.js` configuration file (you can omit the `eslint-plugin-` prefix)\nand either use one of the two configurations available (`recommended` or `all`) or configure the rules you want:\n\n### The recommended configuration\n\nThe `plugin.configs.recommended` config enables a subset of [the rules](#white_check_mark-rules) that should be most useful to most users.\n*See [lib/configs/rules/recommended.ts](https://github.com/ota-meshi/eslint-plugin-regexp/blob/master/lib/configs/rules/recommended.ts) for more details.*\n\n```js\n// eslint.config.js\nimport regexpPlugin from \"eslint-plugin-regexp\"\n\nexport default [\n regexpPlugin.configs.recommended,\n];\n```\n\n### Advanced Configuration\n\nOverride/add specific rules configurations. *See also: [http://eslint.org/docs/user-guide/configuring](http://eslint.org/docs/user-guide/configuring)*.\n\n```js\n// eslint.config.js\nimport regexpPlugin from \"eslint-plugin-regexp\"\n\nexport default [\n {\n plugins: { regexp: regexpPlugin },\n rules: {\n // Override/add rules settings here, such as:\n \"regexp/rule-name\": \"error\"\n }\n }\n];\n```\n\n### Using the all configuration\n\nThe `plugin.configs.all` config enables all rules. It's meant for testing, not for production use because it changes with every minor and major version of the plugin. Use it at your own risk.\n*See [lib/configs/rules/all.ts](https://github.com/ota-meshi/eslint-plugin-regexp/blob/master/lib/configs/rules/all.ts) for more details.*\n\n\u003c!--USAGE_SECTION_END--\u003e\n\n## :white_check_mark: Rules\n\n\u003c!-- begin auto-generated rules list --\u003e\n\nπŸ’Ό Configurations enabled in.\\\n⚠️ Configurations set to warn
