regexp/no-obscure-range ​

💼 This rule is enabled in the ✅ plugin:regexp/recommended config.

disallow obscure character ranges

📖 Rule Details ​

The character range operator (the - inside character classes) can easily be misused (mostly unintentionally) to construct non-obvious character class. This rule will disallow all non-obvious uses of the character range operator.

🔧 Options ​

{
  "regexp/no-obscure-range": ["error",
    {
      "allowed": "alphanumeric" // or "all" or [...]
    }
  ]
}

{
  "regexp/no-obscure-range": ["error",
    {
      "allowed": "alphanumeric" // or "all" or [...]
    }
  ]
}

This option can be used to override the allowedCharacterRanges setting.

It allows all values that the allowedCharacterRanges setting allows.

"allowed": "alphanumeric" ​

"allowed": "all" ​

"allowed": [ "alphanumeric", "😀-😏" ] ​
