required_if global validator

[Liwoj]

required_if validator is mentioned in rules package README and in most translation files but it is actually nowhere to find.

Was it actually removed and what I see is just some remnants of the past ?

Thanks

For anyone interested, this is my own TS implementation (note that some types in use are actually Vee-validate internal types I was forced to replicate in my own project):

/**
 * Rule that makes a field required if another field is set to a certain value.
 * @param otherField - name of the field to compare with
 * @param valueOfOtherField - value of the other field that forces the current field to be required
 */
export function required_if(otherField: string, valueOfOtherField: unknown): GenericValidateFunction {
  return (value: unknown, ctx: FieldValidationMetaInfo) => {
    if (isEmpty(ctx.form[otherField]) || ctx.form[otherField] !== valueOfOtherField)
      return true

    return required(value, ctx)
  }
}
