:book: Usage

<!--USAGE_SECTION_START-->

Add regexp to the plugins section of your eslint.config.js configuration file (you can omit the eslint-plugin- prefix) and either use one of the two configurations available (recommended or all) or configure the rules you want:

The recommended configuration

The plugin.configs.recommended config enables a subset of the rules that should be most useful to most users. See lib/configs/rules/recommended.ts for more details.

// eslint.config.js
import regexpPlugin from "eslint-plugin-regexp"

export default [
    regexpPlugin.configs.recommended,
];

Advanced Configuration

Override/add specific rules configurations. See also: http://eslint.org/docs/user-guide/configuring.

// eslint.config.js
import regexpPlugin from "eslint-plugin-regexp"

export default [
    {
        plugins: { regexp: regexpPlugin },
        rules: {
            // Override/add rules settings here, such as:
            "regexp/rule-name": "error"
        }
    }
];

Using the all configuration

The 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. See lib/configs/rules/all.ts for more details.
