Release 2.3

Release 2.3 comprised the following changes to Release 2.2:

• The new activate and deactivate statements allow control of executing whenever bodies (§ 7.5.4, page ).

• The whenever_stmts(agent), active_agents(), current_whenever(), and last_whenever_executed() built-in functions provide information regarding which agents generate what events, to be used in conjunction with activate and deactivate (§ 10.9, page ).

• Each host now runs at most one copy of the Glish daemon glishd. The Glish interpreter periodically probes the daemon and generates events if connectivity is lost or regained, or if the daemon terminates (§ 16.2, page ).

• A new agent record, ``system'', manages information about the general environment where a script runs. It also generates events indicating that the environment has changed. (See § 10.11, page .)

• The ``version'' global has been removed, as it's now subsumed by ``system.version''.

• An ``include'' directive supports including the contents of one Glish source file inside another (§ 4.15, page ).

• When running Glish interactively, you can now create clients and set up ``whenever'' statements to respond to their events.

• You can use ``=='' and ``!='' operators to compare record, function, agent, and opaque values (§ 4.4, page ).

• The Glish interpreter now allows only one filename on the command line (since the ``include'' directive can be used to access multiple sources). Because of this change, you no longer need the special "-" argument to delimit the end of source filenames and the beginning of script arguments. See § 13.1, page .

• A new program (not a Glish client), tell_glishd, is available for controlling the Glish daemon on a given host (tell_glishd was removed).
