This pages provides information about the PNtalk system. You may find the latest release, documentations, and news here. The authors would be grateful for obtaining a feedback about using the PNtalk system, new ideas or the system improvement.
PNtalk for Squeak
PNtalk can be distributed under MIT LICENCE. The software depends on other software packages (available on SqueakMAP) distributable under the SqueakL+MIT license.
open FileList browser and install the PNtalk.sar file
the PNtalk is ready to use now – open the help window (use command 'PNtalkSystem welcome')
How to use prepared image:
unzip the archive
run the image (squeak file.image)
the PNtalk is ready to use now – there are opened basic windows (MyRepository and help)
Multilevel system: This example shows using different levels (nets) and their synchronization by synchronous ports. The class WfTest describes the implementation of this problem in PNtalk (see the image, PNtalk-Core-Documentation category).
