Release 2.4

Release 2.4 comprised the following changes to Release 2.3:

• Glish now has a mechanism for synchronous request/reply events:

      result := request a->b( 1:10 )
  

  sends a b event to a with value 1:10 and then waits for a to reply. The value of a's reply is stored in result. Note that request is a new keyword, which may cause incompatibilities (syntax errors) with existing scripts that have variables with that name. (See § 7.4, page  for details.)

• The ``event-send'' statement now takes an optional send keyword. That is, you can write

      foo->bar( args )
  

  instead as

      send foo->bar( args )
  

  The belief is that using send will lead to more readable scripts, and the plan is to gradually phase in send as a mandatory keyword.

• The Client library now includes a member function:

      int Client::HasEventSource()
  

  which returns true if a Glish client has any input source (either a connection to the Glish interpreter, or by reading from stdin), and false if it has no input source (due to using -noglish) (Chapter 15, page ).

• The [] expression now returns a truly empty array (§ 3.1.4, page ).
