Function `dmd.staticcond.evalStaticCondition`

Semantically analyze and then evaluate a static condition at compile time. This is special because short circuit operators &&, || and ?: at the top level are not semantically analyzed if the result of the expression is not necessary.


						
				bool evalStaticCondition
				(
				

				  dmd.dscope.Scope* sc,
				

				  Expression original,
				

				  Expression e,
				

				  out bool errors,
				

				  dmd.root.array.Array!(dmd.expression.Expression)* negatives = null
				

				);

Parameters

Name	Description
sc	instantiating scope
original	original expression, for error messages
e	resulting expression
errors	set to `true` if errors occurred
negatives	array to store negative clauses

Returns

true if evaluates to true
