Re: [Pharo-users] [Modeling with Pharo] How to model a simple human interaction.

by aryehof

Your using an object-oriented language, why not use an object /domain model/? Consider that Kristen Nygaard stated that an object-oriented "program execution is regarded as a physical model, simulating the behavior of either a real or imaginary part of the world." By physical model, he really is meaning a "direct model" where you /directly /represent the concepts of your problem domain as objects that interact with each other. Sure, you could use a state machine, but why build a model (your domain problem) on top of a model (a state machine) using a paradigm intended to support a different way. State machines are a favored way to model process and state in functional programming. A domain model would separate the user interaction from your domain problem itself. You would model an Order that knows a User and one or more Images. Anyway, hopefully some food for thought. -- Aryeh -- View this message in context: http://forum.world.st/Modeling-with-Pharo-How-to-model-a-simple-human-inter… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] crash.dmp of OSSubProcess on Pharo 6.0

That VM is (was) a 6.0 alpha.

Mariano, yes I was using the 64 bit pharo. I downloaded the 32 bit pharo 6.0 and it works just fine. Thanks.

Hi John, Was this using 64bits flavor ? If true, can you try with 32 and let me know? I ask because I know OSSubprocess doesn't work on 64 bits yet, but to fix this I need some pull requets merged in the VM...

Re: [Pharo-users] [Moose-dev] dynamic interaction with Mondriam

by Alexandre Bergel

Hi! Simply using Mondrian is complicated to do this (Mondrian is not made to produce interactive & dynamic visualizations). Instead, it would be great that you could try DataStudio, which is exactly designed for this kind of situations. You can load DataStudio by using a dedicated plugin: You can try some examples: | c | c := CAArtwork new. c doAction: (CAAddElementAction new argument: (1 to: 7)). c doAction: (CAAddEdgeAction new argument: [ :e | e + 1 ]). c doAction: (CASwitchLabelAction new). c doAction: (CAShapeSizeAction new argument: 30). c doAction: (CAGridLayoutAction new). ^ c view Here another example: | c | c := CAArtwork new. c doAction: (CAAddElementAction new argument: (Collection withAllSubclasses)). c doAction: (CAAddEdgeAction new argument: #subclasses). c doAction: (CAShapeHeightAction new argument: [ :cls | cls numberOfMethods max: 5 ]). c doAction: (CAShapeWidthAction new argument: [ :cls | cls numberOfVariables * 5 max: 5 ]). c doAction: (CAShapeNormalizedColorAction new argument: [ :cls | cls numberOfLinesOfCode ]). c doAction: (CATreeLayoutAction new). c doAction: (CAAddGroupAction new argument: [ :cls | '*Array*' match: cls name ]). c doAction: (CASwitchLabelAction new). ^ c view You will end-up with something like: Let me know how it goes...
