HISTORY  view on Meta::CPAN

It provides a high level interface to select(), and a very high level
interface to TCP client and server socket operations.  It does not fork.

Face is the start of a curses-based UI framework that can run alone
or use Serv as its main loop.

The code and a rough draft of the documentation are available from
<http://www.shadow.net/~troc/perlstuff.html>.  If this code is useful
to anyone, I'd sure like to know.

There are tied hash packages that implement object naming
and message passing between named objects within the same
process.  The packages allow invocations like:

  $msg{'desktop,paint'} = 1;
  $msg{'name entry,value'} = 'J. K. Cohen';
  $active_flag = $msg{'active checkbox,value'};

The packages also do broadcasting to subsets of the object
dictionary.  Hash stores and fetches are sent to or taken
from all the objects that match the supplied name.  So to
clear the value of all objects that have 'entry' in their
names:

  $msg{'entry,value'} = '';

That clears 'name entry' and 'age entry' and 'salary entry'
and ....

Anyway, the names could be extended to work across sockets
in the presence of a standard select/event loop:

  $gnats_queue = $msg{'//somewhere.com:4242/stickynote/gnat?count'};
  print "gnat has $gnats_queue unread sticky notes.\n";

  $message = 'hello, world!';
  $msg{'//somewhere.org:4242/stickynote/merlyn?queue'} = $message;

Man pages for ObjDict::Names and ObjDict::Messages are
on-line at <http://www.nexi.com/troc>.  The code is inside
a larger package, Serv+Face, at
<http://www.shadow.net/~troc/perlstuff.html>.

Just some ideas to ponder.
