Feedback: Using Output as the Next Input
by Dan 03 May '15

03 May '15

Howdy, A class is instantiated and produces output in a data structure (array, collection, dictionary, ...). Upon each later (maybe months later) instantiation, the previous output is needed as input. What is the best way to do this for modest (not huge) output? Some possibilities: Externally - file out and file in Within the class - compile class methods containing the output; save with Montecello I'm interested in how to dynamically compile a class method. Can Browser be invoked dynamically? In studying Browser and friends, it looks complicated. Am I missing something or attempting something foolish or ...? - Dan

I see there are over 700 packages out there for the choosing. A great variety. It's unfortunate that not all run on the current release of Squeak but maybe with a little work... ;) > > Would users find saving the image as... to be the expected way of > doing things? > > > > - Dan > > Depends on who your users are.

The output is a dictionary and the rules specify that no pair can be the same as previous (up to 3) instances. There are other rules and often hundreds of iterations take place before all pairs obey all the rules. It might be used, as it is in our family, to draw names for Christmas. The person who runs the program distributes the results to those on the list. - Dan

Help needed

I get an app that I made in Squeak. I would like to print the content of some OrderedCollection but don't know how to do that. I thought to us a FileStream but never worked with Stream before any clue or reference is welcome. My objectif is to print a list of my orderedCollection. I want a hard copy... Raymond Asselin
