Boolean operations

Pulsar supports boolean operations such as and, or but the syntax is a bit different than in other languages. Instead of operators, you use functions:

{[ if @and(var1, var2) ]}
  Executes when both var1 and var2 == true
{[/]}

You can also chain boolean operations, using functions inside functions:

{[ if @and(var1, @or(var2, var3)) ]}
  Executes when var1 == true and one of var2, var2 == true
{[/]}

The following boolean functions are available:

And

and results to true when all statements were true. and is a variadic function, and it can take as many parameters as you want:

{[ if @and(true, true, true, true, false) ]}
  Never executes because one of the statements was false
{[/]}

Or

or results to true when at least one of the statements is true. or is a variadic function, and it can take as many parameters as you want:

{[ if @and(false, false, false, true, false) ]}
  Executes because one of the statements was true
{[/]}

Not

not negates the boolean value, meaning true becomes false and vice versa.

{[ if @not(false) ]}
  Executes because false was negated to true
{[/]}

Note from developers: We are planning to add support for true operators as soon as possible, so consider this a workaround. For more complex logic, you should opt to use javascript helpers instead.

There are engine-related challenges with supporting operators that need to be solved before they can be implemented, especially about precedence controlled with brackets (var1 && var2) || var3 , as brackets are currently exclusively used for function invocations.
