if-empty-object

Summary: Empty object following if

Category: Bugs

Avoid

package policy

import rego.v1

allow if {}

Rationale​

An empty rule body would previously be considered an error by OPA. With the introduction, and use of the if keyword, that is no longer the case. In fact, empty {} is not considered a rule body at all, but rather an empty object, meaning that if {} will always evaluate. This is likely a mistake, and while hopefully caught by tests, should be avoided.

Configuration Options​

This linter rule provides the following configuration options:

rules:
  bugs:
    if-empty-object:
      # one of "error", "warning", "ignore"
      level: error
