Using regex in rules

The following classes of rules support regex:

• *-allowed-list
• *-disallowed-list
• *-pattern

As does the ignore* secondary options.

Enforce a case

You can use the regex that corresponds to your chosen case convention:

• kebab-case: ^([a-z][a-z0-9]*)(-[a-z0-9]+)*$
• lowerCamelCase: ^[a-z][a-zA-Z0-9]+$
• snake_case: ^([a-z][a-z0-9]*)(_[a-z0-9]+)*$
• UpperCamelCase: ^[A-Z][a-zA-Z0-9]+$

For example, for lowerCamelCase class selectors use "selector-class-pattern": "^[a-z][a-zA-Z0-9]+$".

All these patterns disallow CSS identifiers that start with a digit, two hyphens, or a hyphen followed by a digit.

Enforce a prefix

You can ensure a prefix by using a positive lookbehind regex.

For example, to ensure all custom properties begin with my- use "custom-property-pattern": "(?<=my-)".
