Request Expressions

 

        Results from clients can be used as part of an expression. The syntax for retrieving a result from a client is exactly the same as sending an event to a client (see § 5.10.1, page )):  

expression -> name ( arg, arg, )

expr -> [ expr ] ( arg, arg, )

If the event is sent to a client as part of an expression, the Glish interpreter waits on the result. When the result is received, it is used in the evaluation of the expression. If no result is needed, the event is simply sent to the client and the interpreter continues.
