`semantic[clause-predicate]`

A clause without WHEN, found by validateContract.

compileSource reports this case earlier, as unsupported[forbid-form] or unsupported[ensure-form]. It appears when validateContract is called directly on a parsed contract.

Example

Through validateContract

CONTRACT Claim {
  ENFORCEMENT_MODE: enforced
  CONTEXT {
    ENTITIES Request {
      count: int
      region: string
      ready: bool
      ratio: float
    }
    CONSTANTS {
      zero: int == 0 [SOURCE:POLICY]
      cap: int == 25 [SOURCE:POLICY]
    }
  }
  TRIGGER {
    grant()
  }
  GUARANTEE {
    ENSURE grant() WHEN Request.ready == true [SOURCE:must_be_ready]
  }
  PROHIBITION {
    FORBID grant [SOURCE:over_cap]
  }
}

rejected semantic[clause-predicate] at 22:5 FORBID predicate required

compileSource reports unsupported[forbid-form] for this source instead, because that check comes first.

Fix

Through validateContract

CONTRACT Claim {
  ENFORCEMENT_MODE: enforced
  CONTEXT {
    ENTITIES Request {
      count: int
      region: string
      ready: bool
      ratio: float
    }
    CONSTANTS {
      zero: int == 0 [SOURCE:POLICY]
      cap: int == 25 [SOURCE:POLICY]
    }
  }
  TRIGGER {
    grant()
  }
  GUARANTEE {
    ENSURE grant() WHEN Request.ready == true [SOURCE:must_be_ready]
  }
  PROHIBITION {
    FORBID grant WHEN Request.count > cap [SOURCE:over_cap]
  }
}
