Re: Network Communications Information Missing From Docs

[address@hidden]

I posted a small TCP (and I suspect UDP) example a while ago, that works for me.

Assuming that the old 'legacy' daytime stream server runs on tcp port 13 (as an 
example).

$ gst daytime.st 
Loading package ObjectDumper
Loading package Sockets
'Sat Jun  6 10:30:16 2020'

As Derek indicated last june, the key issue is the namespace support.

The class below is Sockets.Socket where Sockets. is the package name and Socket 
the class name:

$ cat daytime.st 

Eval [

PackageLoader fileInPackage: 'Sockets'.

s _ Sockets.Socket remote:(Sockets.SocketAddress createLoopbackHost) port:13.
(s upTo: Character cr) printNl.
s close.
