Installation

You'll first need to install ESLint:

npm i eslint --save-dev

Next, install eslint-plugin-ascii-x:

npm install eslint-plugin-ascii-x --save-dev

Usage

Add ascii-x to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
    "plugins": [
        "ascii-x"
    ]
}

Then configure the rule.

{
    "rules": {
        "ascii-x/ascii": "error"
    }
}

Rules

🔧 Automatically fixable by the --fix CLI option.

Planned Features
