# 🔧 Options

{
    "san/no-unused-vars": ["error", {
        "ignorePattern": "^_"
    }]
}

ignorePattern ... disables reporting when your definitions of s-for directives or scope attributes match your ignorePattern Regular expression. default null, will ignore nothing

# 🚀 Suggestion

When your ignorePattern set to ^_, we could provide a suggestion which add a prefix_ to your variable and no more eslint error
